In a little tent pitched in the midst of an Arab camp in the extreme south of Southern Algeria Craven sat writing. A day of intense heat had been succeeded by a night airless and suffocating, and he was wet with perspiration that dripped from his forehead and formed in sticky pools under his hand, making writing laborious and difficult, impossible indeed except for the sheet of blotting paper on which his fingers rested. His thin silk shirt, widely open at the throat, the sleeves rolled up above his elbows, clung limply to his broad shoulders. A multitude of tiny flies attracted by the light circled round the lamp eddying in the heat of the flame, immolating themselves, and falling thickly on the closely written sheets of paper that strewed the camp table, smeared the still wet ink and clogged his pen. He swept them away impatiently from time to time. Squatting on his heels in a corner, his inscrutable yellow face damp and glistening, Yoshio was cleaning a revolver with his usual thoroughness and precision. A ragged square of canvas beside him held the implements necessary to his work, set out in methodical order, and as he cleaned, and oiled and polished assiduously without raising his eyes his deft fingers selected unerringly the tool he required. The weapon appeared already speckless, but for some time he continued to rub vigorously, handling it with almost affectionate care as if loth to put it down; at last with a grunt of demur he reluctantly laid aside the cloth he was using and wrapping the revolver in a silk handkerchief slid it slowly into a leathern holster which his care had kept soft and pliable. Placing it noiselessly on the ground before him he turned his oblique gaze on Craven and watched him for a moment or two intently. Assured at length that his master was too absorbed in his own task to notice the doings of his servant he reached his hand behind him and produced a second revolver, which he began to clean more hurriedly, more superficially than the first, keeping the while a wary eye on the stooping figure at the table. When that too was finished to his satisfaction and restored to his hip pocket, a flicker of almost childlike amusement crossed his usually immobile features and he started operations with an air of fine unconsciousness upon one of a couple of rifles that stood propped against the tent wall near him. Two years of hardships and danger had left no mark upon him, the deadly climate of the region through which he had passed had not impaired his powerful physique, and disease that had ravaged the scientific mission had left him, like Craven, unscathed. With no care beyond his master's comfort, indifferent to fatigue and perils, the months spent in Central Africa had been far more to his taste than the dull monotony of the life at Craven Towers. But with his face turned, though indirectly, toward home—the home of his adoption—Yoshio was still cheerful. For him life held only one incentive—the man who had years before saved his life in California. Where Craven was Yoshio was content.

Outside, the Arab camp was in an uproar. Groups of tribesmen passed the tent continually, conversing eagerly, their raucous voices rising shrill, shouting, arguing, in noisy excitement. The neighing of horses came from near by and once a screaming stallion backed heavily against the canvas wall where Yoshio was sitting, rousing the phlegmatic Japanese to an unwonted ejaculation of wrath as he ducked and grabbed into safety the remaining rifle before the animal was hauled clear with a wealth of detailed Arabic expletives, and he grinned broadly when an authoritative voice broke into the Arabs' clamour and a subsequent sudden silence fell in the vicinity of the stranger's tent.

Regardless of the disturbance resounding from all quarters of the camp Craven wrote on steadily for some time longer. Then with a short sigh he shuffled the scattered sheets together, brushed clear the clinging accumulation of scorched wings and tiny shrivelled bodies, and without re-reading the closely written pages stuffed them into an envelope, and having closed and directed it, leaned back with an exclamation of relief.

The letter to Peters was finished but there remained still the more difficult letter he had yet to address to his wife—a letter he dreaded and yet longed to write. A letter which, reaching her after the death he confidently expected and earnestly prayed for, would reveal to her fully the secret of his past and the passion that had driven him, unworthy, from her. For never during the two years of adventure and peril had death seemed more imminent than now, and before he died he would give himself this one satisfaction—he would break the silence of years that had eaten like a canker into his soul. At last she would know all he had never dared to tell her, all his hopeless love, all his remorse and shame, all his passionate desire for her happiness.

Scores of times during the last two years he had attempted to write such a letter and had as often refrained, but to-night his need was imperative. It was his last chance. In the early hours of the dawn he would ride with his Arab hosts on a punitive expedition from which he had no intention of returning alive. Death that he had courted openly since leaving England would surely be easy to find amid the warring tribes with whom he had thrown in his lot. A curious smile lit his face for an instant, then passed abruptly at the doubt that shook his confidence. Would fate again refuse him release from a life that had become more than ever intolerable?

Haunted as he was with the memory of O Hara San, tortured with longing for the woman he had made his wife, the double burden had become too heavy to bear. He had grasped at the opportunity offered by the scientific mission. The dangerous nature of the country, the fever that saturated its swamps and forests, was known to him and he had gone to Africa courting a death that would free him and yet leave no stain on the name borne by his wife. And the death that would free him would free her too! The bitter justice of it made him set his teeth. For he had left her his fortune and his great possessions unrestrictedly to deal with as she would. Young, rich and free! Who would claim what he had surrendered? Even now, after months of mental struggle, the thought was torment.

But death that had laid a heavy toll on his companions had turned away from him. Disease and disaster had dogged the mission from the outset. The medical and scientific researches had proved satisfactory beyond expectation, but the attendant loss of life had been terrible, and himself utterly reckless and heedless of all precautions Craven had watched tragedy after tragedy with envy he had been hardly able to hide. Immune from the sudden and deadly fevers that had swept the camps periodically with fatal results he had worked fearlessly and untiringly among the stricken members of the mission and the fast dwindling army of demoralised porters who had succumbed with alarming rapidity. With the stolid Japanese always beside him he had wrestled entire nights and days to save the expedition from extermination. And in the intervals of nursing, and shepherding the unwilling carriers, he had ranged far and wide in search of fresh food to supply the wants of the camp. The danger he deliberately sought, with a rashness that had provoked open comment, had miraculously evaded him. He had borne a charmed life. He had snatched at every hazardous enterprise, he had exposed himself consistently to risk until one evening shortly before the expedition was due to start on the return march to civilization, when a chance word spoken by the camp fire had brought home to him abruptly the dependence of the remnant of the mission on him to bring them to the coast in safety. By some strange dealing of fate it had been among the non-scientific members of the expedition that mortality had ranged highest; the big game hunters, though hardier and physically better equipped than the students of the party for hardship and endurance had, with the exception of Craven himself, been wiped out to a man. It had been an unpremeditated remark uttered in all good faith with no ulterior motive by a shuddering fever-stricken scientist writing up his notes and diary by the light of the fire with trembling fingers that could scarcely hold the fountain pen that moved laboriously driven by an indomitable will. A grim jest, horrible in its significance, had followed the startling utterance and Craven had looked with perplexity at the shivering figure with its drawn yellow face from which a pair of glittering eyes burned with an almost uncanny brilliance until the meaning of the man's words slowly penetrated. But the true importance of the suggestion once realised had aroused in him a full understanding of the duty he owed to the men he had undertaken to lead. Of those who could have convoyed the expedition on its homeward march only he remained. Without him the survivors of the once large party might eventually reach safety but it was made clear to him that night how completely his companions relied on him for a quick return and for the management of the train of porters whose frequent mutinies only Craven seemed able to quell. He had sat far into the night, staring gloomily into the blazing fire, smoking pipe after pipe, listening to the multifarious noises of the forest—the sudden distant crash of falling trees, the incessant hum of insect life, the long-drawn howl of beasts of prey hovering on the outskirts of the camp, the soft whoo-whoo of an owl whose cry brought vividly to his mind the cool fragrance of the garden at Craven Towers and the nearer more ominous sounds of muffled agony that came from a tent close beside him where yet another victim of science was gasping his life away.

Hour after hour he sat thinking. There was no getting away from it—it was only despicable that he had not himself recognised it earlier. The narrow path of duty lay before him from which he might not turn aside to ease the burden of a private grief. He was bound to the men who trusted him. Honour demanded that he should forego the project he had formed—until his obligation had been discharged. Loyalty to his companions must come before every selfish consideration. After all it was only a postponement, he reflected with a kind of grim satisfaction. The residue of the mission once safely conducted to the coast his responsibility would end and he would be free to pursue the course that would liberate the woman he loved.

In the chill silence of the hour that precedes the dawn he had risen cramped and shivering from his seat by the dying fire and too late then to take the rest he had neglected, had roused Yoshio and started on the usual foraging expedition that was his daily occupation. And from that time he had been careful of a life which, though valueless to him, was invaluable to his companions. From that time, too, the ill-luck that had pursued them ceased. There had been no more deaths, no more desertions from the already depleted train of carriers. The work had gone forward with continuing success and, six months ago, after a hazardous march through a hostile country, Craven had led the remnant of the expedition safely to the coast. He had waited for some weeks at the African port after the mission had returned to England, and then embarking on a small trading steamer, had made his way northward to an obscure station on the Moroccan seaboard, when by a leisurely and indirect route he had slowly crossed the desert to the district where he now was and which he had reached only a week ago. Twice before he had visited the tribe as the guest of the Sheik Mukair Ibn Zarrarah's younger son, an officer of Spahis whom he had met in Paris, and the warm hospitality shown him had left a deep impression. A sudden unaccountable impulse had led him to revisit a locality where he had spent some of the happiest months of his life. He had conceived an intense admiration and liking for the stern old Arab Chief and his two utterly dissimilar sons; the elder a grave habitually silent man, who clung to the old traditions with the rigid tenacity of the orthodox Mohammedan, disdainful of the French jurisdiction under which he was compelled to live, and occupied solely with the affairs of the tribe and his beautiful and adored wife who reigned alone in his harem, despite the fact that she had given him no child; the younger in total contrast to his brother, a dashing ultra-modern young Arab as deeply imbued with French tendencies as the conservative Omar was opposed to them. The wealthy and powerful old Sheik, whose friendship had been assiduously sought by the French Administration to ensure the co-operation of a tribe that with its far reaching influence might have proved a dangerous element in an unsettled district, shared in his inmost heart the sentiments of his heir, but with a larger and more discriminating wisdom saw the desirability of associating at least one of his family with the Government he was obliged, though grudgingly and half contemptuously, to acknowledge. He had hovered long between prejudice and policy before he reluctantly gave his consent for SaÏd to be placed on the roll of the regiment of Spahis. And the unusual love existing between the two brothers had survived a test that might have proved too strong for its continuance; Omar, bowing to the decision of the autocratic old Chief, had refrained even from comment, and SaÏd, despite his enthusiasm, had carefully avoided inflaming his brother's deeply rooted hatred of the nation the younger man was proud to serve. His easy-going nature adapted itself readily to the two wholly separate lives he lived, and though secretly preferring the months spent with his regiment he contrived to extract every possible enjoyment from the periods of leave for which he returned to the tribe where, laying aside the picturesque uniform his ardent soul rejoiced in and scrupulously suppressing every indication of his Francophile inclinations he resumed with consummate tact the somewhat invidious position of younger son of the house.

The meeting of the young Spahi with Craven in Paris had led to the discovery of similar tastes and ultimately to an intimate friendship. Together in Algeria they had shot panther and Barbary sheep and eventually Craven had been induced to visit the tribe, where he had seen the true life of the desert that appealed strongly to his unconventional wandering disposition. The heartiness of his reception had been unqualified, even the taciturn Omar had unbent to the representative of a nation he felt he could respect with no loss of prestige. To Craven the weeks passed in the Arab camp had been a time of uninterrupted enjoyment and a second visit had strengthened mutual esteem. Situated on the extreme fringe of the Algerian frontier, in the heart of a perpetually disturbed country, the element of danger prevailing in the district was to Craven not the least of its attractions. It had been a source of keen disappointment that during both his visits there had been a cessation of the intertribal warfare that was carried on in spite of the Government's endeavours to preserve peace among the great desert families. For generations the tribe of Mukair Ibn Zarrarah had been at feud with another powerful tribe which, living further to the south and virtually beyond the suzerainty of the nominal rulers of the country, harried the border continually. But, aware of the growing power and resources of Mukair Ibn Zarrarah, for many years the marauders had avoided collision with him and confined their attention to less dangerous adversaries. The apparent neglect of his hereditary enemies had not, however, lessened the old Sheik's precautions. With characteristic oriental distrust he maintained a continual watch upon them and a well organized system of espionage kept him conversant with all their movements. Often during his visits Craven had listened to the stories of past encounters and in the fierce eager faces around him he had read the deep longing for renewed hostilities that animated the younger members of the tribe in particular and had wondered what spark would eventually set ablaze the smouldering fires of hatred and rivalry that had so long lain dormant. And it had been really a subconscious presage of such an outbreak that had brought him back to the camp of Mukair Ibn Zarrarah. His presentiment, the outcome of earnest desire, had been fulfilled, and in its fulfilment attended with horrible details which, had it not been already his intention, would have driven him to beg a place in the ranks of the punitive force that was preparing to avenge an outrage that involved the honour of the tribe. A week ago he had arrived to find the camp seething with an infuriated and passion-swayed people who bore no kind of resemblance to the orderly well-disciplined tribesmen he had seen on his former visits, and the daily arrival of reinforcements from outlying districts had kept the tension strained and swelled the excitement that rioted day and night.

In the barbaric sumptuousness of his big tent and with a calm dignity that even tragedy could not shake the old Sheik had received him alone, for the unhappy Omar was hidden in the desolate solitude of his ravished harem. To the Englishman, before whom he could speak openly the old man had revealed the whole terrible story with vivid dramatic force and all the flowery eloquence of which he was master. It was a tale of misplaced confidence and faithlessness that, detected and punished with oriental severity, had led to swift and dastardly revenge. A headman of the tribe whom both the Sheik and his elder son trusted implicitly had proved guilty of grave indiscretion that undetected might have seriously impaired the prestige of the ruling house. Deposed from his headmanship, and deserted with characteristic vacillation by the adherents on whom he counted, the delinquent had fled to the camp of the rival tribe, with whom he had already been in secret negotiation. This much Mukair Ibn Zarrarah's spies had ascertained, but not in time to prevent the catastrophe that followed. Plans thought to be known only to the Sheik and his son had been disclosed to the marauding Chief, who had long sought an opportunity of aiming an effectual blow at his hated rival, and on one of Omar's periodical tours of inspection to the more remote encampments of the large and scattered tribe, the little caravan had been surrounded by an overwhelmingly superior force led by the hereditary enemy and the renegade tribesman. Hemmed in around the litter of the dearly loved young wife, from whom he rarely parted, Omar and his small bodyguard had fought desperately, but the outcome had been inevitable from the first. Outnumbered they had fallen one by one under the vigorous onslaughts of the attacking party who, victorious, had retired southward as quickly as they had come, carrying with them the beautiful Safiya—the price of the traitor's treachery. Covered with wounds and left for dead under a heap of dying followers Omar and two others had alone survived, and with death in his heart the young man had lived only for the hour when he might avenge his honour. Animated by the one fierce desire that sustained him he had struggled back to life to superintend the preparations for retaliation that should be both decisive and final. To old injuries had been added this crowning insult, and the tribe of Mukair Ibn Zarrarah, roused to the highest pitch of fury, were resolved to a man to exterminate or be exterminated. The preparations had been almost completed when Craven arrived at the camp, and tonight, for the first time, at a final war council of all the principal headmen held in the Sheik's tent, he had seen the stricken man and had hardly recognized in the gaunt attenuated figure that only an inflexible will seemed to keep upright, the handsome stalwart Arab who of all the tribe had most nearly approached his own powerful physique. The frenzied despair in the dark flashing eyes that met his struck an answering chord in his own heart and the silent handclasp that passed between them seemed to ratify a common desire. Here, too, was a man who for love of a woman sought death that he might escape a life of terrible memory. A sudden sympathy born of tacit understanding seemed to leap from one to the other, an affinity of purpose that drew them strangely close together and brought to Craven an odd sense of kinship that dispelled the difference he had felt and enabled him to enter reservedly into the discussions that followed. After this meeting he had gone back to his tent to make his own final preparations with a feeling almost of exhilaration. To Yoshio, more than usually stolid, he had given all necessary instructions for the conveyance of his belongings to England.

Remained only the letter to his wife—a letter that seemed curiously hard to begin. Pushing the writing materials from him he leant back further in his chair, and searching in his pockets found and filled a pipe with slow almost meticulous deliberation. Another search failed to produce the match he required, and rising with a prolonged stretch he bent over the table and lit his pipe at the lamp. Crossing the tent he stood for a few moments in the doorway, but movements did not seem to produce inspiration, and with an impatient shrug he returned to his seat and sat staring gloomily at the blank sheet of paper before him. The flaring light of the lamp illuminated his deeply tanned face and lean muscular figure. In perfect physical condition and bronzed with the African sun, he looked younger than when he had left England. At that moment death and Barry Craven seemed very widely separated—and yet in a few hours, he reflected with a curiosity that was oddly impersonal, the vultures might be congregating round the body that was now so strong and virile. “Handsome Barry Craven.” He had heard a woman say it in Lagos with a feeling of contemptuous amusement—a cynical smile crossed his face as the remark recurred to him and he pictured the loathing that would succeed admiration in the same woman's eyes if she could see what would remain of him after the scavengers of the desert had done their work. The thought gave him personally no feeling of disgust. He had lived always too near to Nature to shrink from contemplation of her merciless laws.

He filled another pipe and strove to collect his wandering thoughts, but the power of definite expression seemed beyond him as there rose in him with almost overwhelming force the terrible longing that never left him—the craving to see her, to hear her voice. Of his own free will he was putting away all that life could mean or hold for him, and in the flood of natural reaction that set in he called himself a fool and revolted at his self-imposed sentence. The old struggle recommenced, the old temptation gripped him in all its bitterness, and never so bitterly as to-night. In the revulsion of feeling that beset him it was not death he shrank from but the thought of eternity—alone. Neither in this world nor in the life everlasting would she be his, and in an agony of longing his soul cried out in anguished loneliness. The yearning for her grew intolerable, a burning physical ache that was torture; but stronger far rose the finer nobler desire for the perfect spiritual companionship that he would never know. By his own act it would be denied him. By his own act he had made this hell in which he lived, of his own making would be the hell of the hereafter. Always he had recognised the justice of it, he did not attempt to deny the justice of it now. But if it had been otherwise—if he had been free to woo her, free to win her to his arms! It was not the least of his punishment that, deep down in his heart, he had the firm conviction that despite her assertions to the contrary, love was lying dormant in her. And that love might have been his, would have been his, for the strength and tenderness of his own passion would have compelled it. She must have turned to him at last and in his love found happiness. And to him her love would have been the crown of life—a life of exquisite joy and beauty, a union of perfect and undivided sympathy. Together they might have made the Towers a paradise on earth; together they might have broken the curse of Craven; together they might have brought happiness into the lives of many. And in the dream of what might have been there came to him for the first time the longing for parenthood, the desire for a child born of the woman he adored, a child who joining in his tiny personality the essentials of each would be a tangible proof of their mutual love, a child who would perpetuate the race he sprang from. Craven's breath came fast with a new and tremendous emotion. Then with terrible suddenness came a lightning flash of recollection, a stabbing remembrance that laid his dream in pieces at his feet. He heard again the low soft sobbing voice, “Are you not glad?” He saw again O Hara San's pleading tear-filled eyes, felt again her slender sorrow-shaken body trembling in his arms, and he bowed his head on his hands in shuddering horror....

Numbed with the pain of memory and self-loathing he was unaware of the renewal of noisy demonstration in the camp that to Yoshio's attentive and interested ears pointed to the arrival of yet another adherent of Mukair Ibn Zarrarah, an adherent of some special standing, judging from the warmth of his reception. Moved by curiosity the Jap rose noiselessly and passing unnoticed by his master vanished silently into the night.

Some little while later the sound of a clear tenor voice calling to him loudly by name sent Craven stumbling to his feet. He turned quickly with outstretched hands to meet the tall young Arab, who burst unceremoniously into the tent and flung himself upon him in boisterous greeting. Gripped by a pair of muscular arms Craven submitted with an Englishman's diffidence to the fervid oriental embrace that was succeeded to his greater liking by a hearty and prolonged English handshake and a storm of welcoming excited and almost incoherent speech. “C'est bien toi, mon vieux! You are more welcome than you have ever been—though I could wish you a thousand miles away, mon ami, but of that, more, later. Dame, but I have ridden! As though the hosts of Eblis were behind me. I was on leave when the messenger came for me—he seems to have been peremptory in his demands, that same Selim. Telegrams despatched to every likely place—one caught me fortunately at Marseilles. Yes, I had been in Paris. I hastened to headquarters and asked for long and indefinite leave on urgent private affairs, all the lies I thought mon colonel would swallow, but no word of war, bien entendu! Praise be to Allah they put no obstacle in my way and I left at once. Since then I have ridden almost without stopping, night and day. Two horses I have killed, the last lies dead of a broken heart before my father's tent—you remember her?—my little Mimi, a chestnut with a white star on her forehead, dear to me as the core of my heart. For none but Omar would I have driven so, for I loved her, look you, mon ami, as I could never love a woman. A woman! Bah! No woman in the world was worth a toss of my Mimi's head. And I killed her, Craven. Killed her who loved and trusted me, who never failed me. My little Mimi! For the love of Allah give me a whisky.” And laughing and crying together he collapsed with a groan on to Craven's bed but sat up again immediately to gulp down the prohibited drink that was almost the last in a nearly depleted flask.

“The Prophet never tasted whisky or he would not have forbidden it to the true believer,” he said with a boyish grin, as he handed back the empty cup.

“Which you are not,” commented Craven with a faint smile. “In the sense you mean, no,” replied SaÏd, swinging his heels to the ground and searching in the folds of his burnous for a cigarette, which he lit and smoked for a few minutes thoughtfully. Then with all trace of his former excitement gone he began to discuss soberly the exigency of the moment, revealing a sound judgment and levelness of mind that appeared incompatible with his seemingly careless and easy-going disposition. It was a deeper studiously hidden side of his character that Craven had guessed very early in their acquaintance.

He talked now with unconcealed seriousness of the gravity of the situation. In the short time he had been with his father before seeking his friend he had mastered the particulars of the projected expedition and, with his European knowledge, had suggested and even—with a force of personality he had never before displayed in the old Sheik's presence—insisted on certain alterations which he detailed now for Craven's benefit, who concurred heartily, for they were identical with suggestions put forward by himself which had been rejected as impossible innovations by the conservative headmen, and conscious of his position as guest he had not pressed them. Then with a sudden change of tone the young Arab turned to Craven in frowning inquiry.

“But you, mon cher, what are you doing in this affair? It was that I meant when I said I wished you a thousand miles away. You are my friend, the friend of all of us, but friendship does not demand that you ride with us to-night. That you would offer—yes—it was only to be expected. But that we should accept your offer—no! a hundred times no! you are an Englishman, a big man in your own country, what have you to do with the tribal warfare of minor Arab Chiefs—voyez vous, I have my moments of modesty! If anything should happen—as happen it very likely will—what will your paternal British Government say? It will only add to my father's difficulties with our own over-lords.” There was a laugh in his eyes though his voice was serious. Craven brushed his objection aside with an indifferent hand.

“The British Government will not distress itself about me,” he said dryly. “I am not of sufficient importance.”

For a few moments the Arab sat silent, smoking rapidly, then he raised his dark eyes tentatively to Craven's face.

“In Paris they told me you were married,” he said slowly, and the remark was in itself ample indication of his European tendencies.

Craven turned away with an abrupt movement and bent over the lamp to light his pipe. “They told you the truth,” he said, with a certain reluctance, his face hidden by a cloud of smoke. “Pourtant, I ride with you to-night.” There was a note of brusque finality in his voice that SaÏd recognised, and he shrugged acquiescence as he lit another cigarette. “It is almost certain death,” he said, with nonchalant oriental calm. But Craven did not answer and SaÏd relapsed into a silence that was protracted. From the midst of the blue haze surrounding him, his earnest scrutiny hidden by the thick lashes that curved downwards to his swarthy cheek, he gazed intently through half-closed eyes at the friend whose presence he found for the first time embarrassing. Fatalist though he was in all things that concerned himself, western influence had bitten deep enough to make him realise that the same doctrine did not extend to Craven. He recognised that self-determination came more largely into the Englishman's creed than into his own. Whether he himself lived or died was a matter of no great moment. But with Craven it was otherwise and he had no liking for the thought that should the morrow's venture go against them his friend's blood would, virtually, be upon his hands! So far had his Francophile tendencies taken him. And the more he dwelt upon the uncomfortable fact the less he liked it. He turned his attention more directly upon the man himself and he noted changes that surprised and disturbed him. The stern weary looking face was not the careless smiling one he remembered. The man he had known had been vividly alive, care-free and animated; one who had jested alike at life and death with an indifferent laugh, but one who though careless of danger even to the extent of foolhardiness had never given any indication of a desire to quit a life that was obviously easy and attractive. But this man was different, grave and abrupt of speech, with an air of tired suffering, and a grim purposefulness in his determination to ignore his friend's warning that conveyed an impression of underlying sinister intent that set the Arab wondering what sting had poisoned his life even to the desire to sacrifice it. For the look on Craven's face was not new to him, he had seen it before—on the face of a French officer in Algiers who had subsequently taken his own life, and again this very evening on the face of his brother Omar. The personalities of the three men were widely different, but the expression of each was identical. The deduction was simple and yet to him wholly inexplicable. A woman—without doubt a woman! In the first two cases it was certainly so, he seemed to know instinctively that here, too, he was not mistaken in his supposition. A puzzled look crept into his fine dark eyes and a cynical smile hovered round his mouth as he viewed these three dissimilar men from the height of his own contemptuous indifference towards any and every woman. It was a weakness he did not understand, a phase of life that held no meaning for him at all. He had never bestowed a second glance on any woman of his own race, the attentions of European women in Paris and Algiers had been met with cold scorn that he masked with racial gravity of demeanour or frank insolence according to circumstances. For him women did not exist; he lived for his horses, for his regiment and for sport. To his strangely cold nature the influence that women exercised over other men was a thing inconceivable—the houris of the paradise of his fathers' creed were to him no incentive to enter the realms of the blessed. A character apart, incomprehensible alike to the warm-blooded Frenchmen with whom he associated and to his own passionate countrymen, he maintained his peculiarity tranquilly, undisturbed by the banter of his friends and the admonitions of his father, who in view of his heir's childlessness regarded his younger son's temperament with growing uneasiness as the years advanced.

The action of the French officer in Algiers had provoked in SaÏd only intolerant contempt but, as he realised tonight, contempt was not possible in the cases of Craven and his brother. He pondered it with a curious feeling of irritation. What was it after all, this emotion of which he was ignorant—this compelling impulse that entered into a man driving him beyond the power of endurance? It was past his comprehension. And he wondered suddenly for the first time why he had been made so different to the generality of men. But introspection was foreign to him, he had not been in the habit of dissecting his own personality and his thoughts turned quickly with greater interest to the man who sat near him plunged like himself into silent reverie. And as he looked he scowled with angry irritation. The Frenchman in Algiers had not mattered, but Omar and Craven mattered very much. He resented the suffering he did not understand—the termination of a friendship he valued, for it was almost inevitable should Craven persist in his decision and the loss of a brother who was dearer to him than he would admit and whose death would mean a greater change in his own life than he cared to contemplate. That through a woman this should be possible! With hearty thoroughness and picturesque attention to detail he silently cursed all women in general and two women in particular. For the seriousness of the venture lay, at the moment, heavily upon him. He was tired and his enthusiasm temporarily damped by the unexpected and incomprehensible attitude of the two men by whom alone he permitted himself to be influenced. But gradually his natural buoyancy reasserted itself, and abandoning as insoluble the perplexing problem, he spoke again eagerly of the impending meeting with his hereditary foes. For half an hour they talked earnestly and then SaÏd rose, announcing his intention of getting a few hours sleep before the early start. But he deferred his going, making one pretext after another for remaining, walking about the little tent in undecided hesitation, plainly embarrassed. Finally he swung toward Craven with a characteristic gesture of his long arms.

“Can I say nothing to deter you from this expedition?”

“Nothing,” replied Craven; “you always promised me a fight some day—do you want to do me out of it now, you selfish devil?” he added with a laugh, to which SaÏd did not respond. With an inarticulate grunt he moved toward the door, pausing as he went out to fling over his shoulder: “I'll send you a burnous and the rest of the kit.”

“A burnous—what for?”

“What for?” echoed SaÏd, coming back into the tent, his eyes wide with astonishment. “Allah! to wear, of course, mon cher. You can't go as you are.”

“Why not?”

The Arab rolled his eyes heavenward and waved his hands in protest as he burst out vehemently: “Because they will take you for a Frenchman, a spy, an agent of the Government, and they will finish you off even before they turn their attention to us. They hate us, by the Koran! but they hate a Frenchman worse. You wouldn't have the shadow of a chance.”

Craven looked at him curiously for a few moments, and then he smiled. “You're a good fellow, SaÏd,” he said quietly, taking the cigarette the other offered, “but I'll go as I am, all the same. I'm not used to your picturesque togs, they would only hamper me.”

For a little while longer SaÏd remained arguing and entreating by turns and then went away suddenly in the middle of a sentence, and for a few minutes Craven stood in the door of the tent watching his retreating figure by the light of the newly risen moon with a smile that softened his face incredibly.

Then he turned back into the tent and once more drew toward him the writing materials.

The difficulty he had before felt had passed away. It seemed suddenly quite easy to write and he wondered why it had appeared so impossible earlier in the evening. Words, phrases, leaped to his mind, sentences seemed to form themselves, and, with rapidly moving pen, he wrote without faltering for the best part of an hour—all he had never dared to say, more almost than he had ever dared to think. He did not spare himself. The tragic history of O Hara San he gave in all its pitifulness without attempting to extenuate or shield himself in any way; he sketched frankly the girl's loneliness and childish ignorance, his own casual and selfish acceptance of the sacrifice she made and the terrible catastrophe that had brought him to abrupt and horrible conviction of himself, and his subsequent determination to end the life he had marred and wasted. He wrote of the coming of John Locke's letter at the moment of his deepest abasement, and of the chance it had seemed to offer; of her own entry into his life and the love for her that almost from the first moment had sprung up within him.

In its entirety he laid bare the burning hopeless passion that consumed him, the torturing longing that possessed him, and the knowledge of his own unworthiness that had driven him from her that she might be free with a freedom that would be at last absolute. But even in this letter which tore down so completely the barrier between them he did not admit to her the true reason of his marriage, he preferred to leave it obscure as it had always been, even should the motive she might attribute to him be the wrong one. He must chance that and the impression it might leave with her. Her future life he alluded to very briefly not caring to dwell on business that was already cut and dried, but referring her to Peters who was fully instructed and on whose advice and help she could count. He expressed no wish with regard to Craven Towers and his other properties, leaving her free to dispose of or retain them as she pleased. He shrank from suggesting in any way that she benefited by his death.

He saw her before him as he wrote. It seemed almost as if the ardent passionate wards were spoken to present listening ears, and as with Peters' letter he did not reread the many closely written sheets. What use? He did not wish to alter or amend anything he had said. He had done, and a deeper peace came to him than he had known since those far away days in Japan.

He called to Yoshio. Almost before the words had left his lips the man was beside him. And as the Jap listened to the minute instructions given him the light that had sprung to his eyes died out of them and his face became if possible more than usually stolid and inscrutable.

“You quite understand?” said Craven in conclusion. “You will wait here until it becomes evident that further waiting is useless. Then you are to go straight back to England and give those letters into Mrs. Craven's own hand.”

With marked reluctance Yoshio slowly took up the two heavy packets and fingered them for a time silently. Then with a sudden exclamation in his own language he shook his head and pushed them back across the table. “Going with master,” he announced phlegmatically, and raised his eyes with a glance that was at once provocative and stubborn. Craven met his direct stare with a feeling of surprise. Only once before had the docile Japanese asserted himself definitely and the memory of it made anger now impossible. He pointed to the letters lying on the table between them. “You have your orders,” he said quietly, and cut short further protests with a quick gesture of authority. “Do as you're told, you obstinate little devil,” he added, with a short laugh. And like a chidden child Yoshio pocketed the letters sullenly. Stifling a yawn Craven kicked off his boots and moved over to the bed with a glance at his watch. He flung himself down, dressed as he was.

“Two hours, Yoshio—not a minute longer,” he murmured drowsily, and slept almost before his head touched the pillow.

For an hour or more, squatting motionless on his heels in the middle of the tent, Yoshio watched him, his mask-like face expressionless, his eyes fixed in an unwavering stare. Then he rose cautiously and glided from the tent.

During the last two years Craven had become accustomed to snatching a few hours of sleep when and how he could. He slept now deeply and dreamlessly. And when the two hours were passed and Yoshio woke him he sprang up, wide awake on the instant, refreshed by the short rest. In silence that was no longer sullen the valet indicated a complete Arab outfit he had brought back with him to the tent, but Craven waved it aside with a smile at the thought of SaÏd's pertinacity and finished his dressing quickly. As he concluded his hasty preparations he found time to wonder at his own frame of mind. He had an odd feeling of aloofness that precluded even excitement. It was as if his spirit, already freed, looked down from some immeasurable height with scant interest upon the doings of a being who wore the earthly semblance of himself but who mattered not at all. He seemed to be above and beyond actualities. He heard himself repeating the instructions he had given earlier to Yoshio, he found himself taking leave of the faithful little Jap and wondering slightly at the man's apparent unconcern. But outside the little tent the strange feeling left him suddenly as it had come. The cool wind that an hour later would usher in the dawn blew about his face dispelling the visionary sensation that had taken hold of him. He drew a deep breath looking eagerly at the beauty of the moon-lit night, feeling himself once more keenly alive, keenly excited at the prospect of the coming venture.

Excitement was rife also in the camp and he made his way with difficulty through the jostling throng of men and horses towards the rallying point before the old Sheik's tent. The noise was deafening, and trampling screaming horses wheeled and backed among the crowd pressing around them. With shouts of acclamation a way was made for the Englishman and he passed through the dense ranks to the open space where Mukair Ibn Zarrarah with his two sons and a little group of headmen were standing. They welcomed him with characteristic gravity and SaÏd proffered the inevitable cigarette with a reproachful glance at his khaki clothing. For a few moments they conversed and then the Sheik stepped forward with uplifted hand. The clamour of the people gave way to a deep silence. In a short impassioned speech the old man bade his tribe go forward in the name of the one God, Merciful and Beneficent. And as his arm dropped to his side again a mighty shout broke from the assembled multitude. Allah! Allah! the fierce exultant cry rose in a swelling volume of sound as the fighting men leaped to their maddened horses dragging them back into orderly ranks from among the press of onlookers and tossing their long guns in the air in frenzied excitement. A magnificent black stallion was led up to Craven, and the Sheik soothed the beautiful quivering creature, caressing his shapely head with trembling nervy fingers. “He is my favourite, he will carry you well,” he murmured with a proud smile as he watched Craven handling the spirited animal. Mounted Craven bent down and wrung Mukair Ibn Zarrarah's hand and in another moment he found himself riding between Omar and SaÏd at the head of the troop as it moved off followed by the ringing shouts of those who were left behind. He had a last momentary glimpse of the old Sheik, a solitary upright figure of pathetic dignity, standing before his tent, and then the camp seemed to slide away behind them as the pace increased and they reached the edge of the oasis and emerged on to the open desert. A few minutes more and the fretting horses settled down into a steady gallop. The dense ranks of tribesmen were silent at last, and only the rythmical thud of hoofs sounded with a muffled beat against the soft shifting sand.

Craven felt himself in strange accordance with the men with whom he rode. The love of hazardous adventure that was in his blood leaped into activity and a keen fierce pleasure swept him at the thought of the coming conflict. The death he sought was the death he had always hoped for—the crashing clamour of the battlefield, the wild tumultuous impact of contending forces, with the whining scream of flying bullets in his ears. To die—and, dying, to atone!

Might that ineffable rest that was promised be even for him? Would his deep repentance, the agony of spirit he had endured, be payment enough? Eternal death—the everlasting hell of the Jehovah of the ancients! Not that, merciful God, but the compassion of Christ:

On that terrible day in Yokohama that seemed so many weary years ago Craven had laid his sin-stained soul in all sincerity and humbleness at the feet of the Divine Redeemer, but with no thought or hope of forgiveness. Always the necessity of personal atonement had remained with him, without which by his reasoning there could be no salvation. That offered, but not until then, he would trust in the compassion that passed man's understanding. And to-night—to-day—he seemed nearer than he had ever been to the fulfilment of his desire. The mental burden that had lain like an actual crushing weight upon him seemed to slip away into nothingness. A long deep sigh of wonderful relief escaped him and he drew himself straighter in the saddle, a new peace dawning in his eyes as he raised them to the starlit sky. Out of the past there flashed into his mind the picture—forgotten since the days of childhood—of Christian freed of his burden at the foot of the Cross, as represented in the old copy of the “Pilgrim's Progress” over which he had pored as a boy, enthralled by the quaint text which he had known nearly by heart and fascinated by the curious illustrations that had appealed to his young imagination.

The years rolled back, he saw himself again a little lad stretched on the rug before the fire in the library at Craven Towers, the big book propped open before him, studying with a child's love of the grotesque the grisly picture of Apollyon whose hideous black-winged form had to his boyish mind been the actual image of the devil, a tangible demon whom he had longed to conquer like Christian armed with sword and shield. The childish idea, a bodily adversary to contend with—it would have been simpler. But the devil in a man's own heart, the insidious inward prompting to sin that unrepelled grows imperceptibly stronger and greater until the realisation of sin committed comes with horrible suddenness! To Craven, as to many others, came the futile longing to have his life to live again, to start afresh from the days of innocency when he had hung, enraptured, over the woodcuts of the “Pilgrim's Progress.” He forced his thoughts back to the present. Death, not life, lay before him. Instinctively he glanced at the man who rode at his right hand. In the cold white moonlight the Arab's face was like a piece of beautiful carved bronze, still and terrible in its fixed intentness. Sitting his horse with evident difficulty, animated by mere strength of will, his wasted frame rigidly upright, his sombre tragic eyes peering steadfastly ahead, he seemed in his grim purposefulness the very incarnation of avenging justice. And as Craven looked at him covertly he wondered what lay hidden behind those set features, what of hope, what of fear, what of despair was seething in the fierce heart of the desert man. Of the dearly loved wife who had been ravished from him there had come no further word, her fate was unknown. Had she died, or did she still live—in shameful captivity, the slave of the renegade who had made her the price of his treachery? What additional horror still awaited the unhappy husband who rode to avenge her? With a slight shudder Craven turned from the contemplation of a sorrow that seemed to him even greater than his own and sought his left hand neighbour. With a quick smile SaÏd's eyes met his. With an easy swing of his graceful body he drew his horse nearer to the spirited stallion Craven was riding but did not speak. The ready flow of conversation that was habitual had apparently forsaken him.

The young Arab's silence was welcome, Craven had himself no desire to speak. The dawn wind was blowing cool against his forehead, soothing him. The easy gallop of the horse between his knees, tractable and steady now he was allowed free rein, was to him the height of physical enjoyment. He would get from it what he could, he thought with a swift smile of self mockery—the flesh still urged in contradiction to his firm resolve. It was a blind country through which they were riding, though seemingly level the ground rose and fell in a succession of long undulating sweeps that made a wide outlook impossible. A regiment could lie hidden in the hollows among the twisting deviating sandy hillocks and be passed unnoticed. And as he topped each rise at the head of the Arab troop Craven looked forward eagerly with unfailing interest. He hardly knew for what he looked for their destination lay many miles further southward and the possibility of unexpected attack had been foreseen by Mukair Ibn Zarrarah, whose scouts had ranged the district for weeks past, but the impression once aroused of an impending something lingered persistently and fixed his attention.

From time to time the waiting scouts joined them, solitary horsemen riding with reckless speed over the broken ground or slipping silently from the shadow of a side track to make a brief report and then take their place among the ranks of tribesmen. So far they told no more than was already known. The wind blew keener as the dawn approached. Far in the east the first faint pinky streaks were spreading across the sky, overhead the twinkling stars paled one by one and vanished. The atmosphere grew suddenly chill. The surrounding desert had before been strangely silent, not so much as the wailing cry of a jackal had broken the intense stillness, but now an even deeper hush, mysterious and pregnant, closed down over the land. For the time all nature seemed to hang in suspense, waiting, watching. To Craven the wonder of the dawn was not new, he had seen if often in many countries, but it was a marvel of which he never tired. And there was about this sunrise a significance that had been attached to no other he had ever witnessed. Eagerly he watched the faint flush brighten and intensify, the pale streaks spread and widen into far flung bars of flaming gold and crimson. Daylight came with startling suddenness and as the glowing disc of the sun rose red above the horizon a horseman broke from the galloping ranks, and spurring in advance of the troop, wheeled his horse and dragged him to an abrupt standstill. Rising in his stirrups he flung his arms in fervid ecstasy toward the heavens. Craven recognised in him a young Mullah of fanatical tendencies who had been particularly active in the camp during the preceding week. That the opposing tribe was of a different sect, abhorred by the followers of Mukair Ibn Zarrarah, had been an original cause of dissent between them, and the priests had made good use of the opportunity of fanning religious zeal.

The cavalcade came to a sudden halt, and as Craven with difficulty reined in his own horse the sustained and penetrating cry of the muezzin rose weirdly high and clear on the morning air, “al-ilah-ilah.” The arresting and solemn invocation had always had for Craven a peculiar fascination, and as the last lingering notes died away it was not purely from a motive of expediency that he followed the common impulse and knelt among the prostrate Arabs. His creed differed from theirs but he worshipped the same God as they, and in his heart he respected their overt profession of faith.

As he rose from his knees he caught SaÏd's eyes bent on him with a curious look in them of interrogation that was at once faintly mocking and yet sad. But the expression passed quickly into a boyish grin as he waved an unlit cigarette toward the fiery young priest who had seized the chance to embark on a passionate harangue.

“When prayer is ended disperse yourselves through the land as ye list,” he murmured, with a flippant laugh at the perverted quotation. “The holy man will preach till our tongues blacken with thirst.” And he turned to his brother to urge him to give the order to remount. Omar was leaning against his horse, his tall figure sagging with fatigue. He started violently as SaÏd spoke to him, and, staggering, would have fallen but for the strong arm slipped round him. And, watching Craven saw with dismay a dark stain mar the whiteness of his robes where a wound had broken out afresh, and he wondered whether the weakened body would be able to respond to the urging of the resolute will that drove it mercilessly, or, when almost within view, the fiercely longed for revenge would yet be snatched from him.

But with an effort the Arab pulled himself together and, mounting, painfully cut short the Mullah's eloquence and gave in a firm tone the desired order.

The swift gallop southward was resumed.

The breeze dropped gradually and finally died away, but for an hour or more the refreshing coolness lingered. Then as the sun rose higher and gained in strength the air grew steadily warmer until the heat became intense and Craven began to look eagerly for the oasis that was to be their first halting place. In full daylight the landscape that by night had seemed to possess an eerie charm developed a dull monotony. The successive rise and fall of the land, always with its limited outlook, became tedious, and the labyrinthine hillocks with their intricate windings seemed to enclose them inextricably. But on reaching the summit of a longer steeper incline that had perceptibly slowed the galloping horses, he saw spread out before him a level tract of country stretching far into the distance, with a faint blue smudge beyond of the chain of hills that SaÏd told him marked the boundary of the territory that Mukair Ibn Zarrarah regarded as his own, the boundary, too, of French jurisdiction. Through a defile in the hills lay the enemy country.

The change was welcome to men and horses alike, the latter—aware with unerring instinct of the nearness of water—of their own accord increased their pace and thundering down the last long shifting slope pressed forward eagerly toward the oasis that Craven judged to be between two and three miles away. In the clear deceptive atmosphere it appeared much nearer, and yet as they raced onward it seemed to come no closer but rather to recede as though some malevolent demon of the desert in wanton sport was conjuring it tantalizingly further and further from them. The tall feathery palms, seen through the shimmering heat haze, took an exaggerated height towering fantastically above the scrub of bushy thorn trees.

Craven had even a moment's doubt whether the mirage-like oasis actually existed or was merely a delusion bred of fancy and desire. But the absurdity of the doubt came home to him as he looked again at the outline of the distant hills—too conspicuous a landmark to allow of any error on the part of his companions to whom the country was familiar.

The prospect of the welcome shade made him more sensitive to the scorching strength of the sun that up till now he had endured without more than a passing sensation of discomfort. He was inured to heat, but to-day's heat was extraordinary, and even the Arabs were beginning to show signs of distress. It was many hours since they started and the pace had been killing. His mouth was parched and his eyeballs smarted with the blinding glare. With the thirst that increased each moment the last half mile seemed longer than all the preceding ride, and when the oasis was at length reached he slipped from his sweating horse with an exclamation of relief.

The Arabs crowded round the well and in a moment the little peaceful spot was the scene of noisy confusion; men shouting, scrambling and gesticulating, horses squealing, and above all the creaking whine of the tackling over the well droning mournfully as the bucket rose and fell. SaÏd swung himself easily to the ground and held his brother's plunging horse while he dismounted. For a few moments they conversed together in a rapid undertone, and then the younger man turned to Craven, a cloud on his handsome face. “Our communication has broken down. Two scouts should have met us here,” he said, with a hint of anxiety in his voice. “It disconcerts our scheme for we counted on their report. They may be late—it is hardly likely. They had ample time. More probably they have been ambushed—the country is filled with spies—in which event the advantage lies with the other side. They will know that we have started, while we shall have no further information. The two men who are missing were the only ones operating beyond the border. The last scout who reported himself was in touch with them last night. From them he learned that two days ago the enemy were forty miles south of the hills yonder. We had hoped to catch them unawares, but they may have got wind of our intentions and be nearer than we expect. The curse of Allah on them!” he added impatiently.

“What are you going to do?” asked Craven with a backward glance at the dismounted tribesmen clustering round the well and busily employed in making preparations for rest and food. SaÏd beckoned to a passing Arab and dispatched him with a hurried order. Then he turned again to Craven. “The horses must rest though the men would go forward at a word. I am sending two scouts to reconnoitre the defile and bring back what information they can,” he said. And as he spoke the two men he had sent for appeared with disciplined promptness and reined in beside him. Having received their brief instructions they started off in a cloud of dust and sand at the usual headlong gallop. SaÏd turned away immediately and disappeared among the jostling crowd, but Craven lingered at the edge of the oasis looking after the fast receding horsemen who, crouched low in their saddles, their long white cloaks swelling round them, were very literally carrying out their orders to ride “swift as the messengers of Azrael.” He had known them both on his previous visits, though he had not recognised them in the dark hours of the dawn when they joined the troop, and remembered them as two of the most dare-devil and intrepid of Mukair Ibn Zarrarah's followers. A moment since they had grinned at him in cheery greeting, exhibiting almost childlike pleasure when he had called them by name, and had set off with an obeisance as deep to him as to their leader.

Incidents of those earlier visits flashed through his mind as he watched them speeding across the glaring plain and a feeling almost of regret came to him that it should be these two particular men who had been selected for the hazardous mission. For he guessed that their chance of return was slight. And yet hardly slighter than for the rest of them! With a shrug he moved away slowly and sought the shadow of a camel thorn. He lay on his back in the welcome patch of shade, his helmet tilted over his eyes, drawing vigorously at a cigarette in the vain hope of lessening the attentions of the swarms of tormenting flies that buzzed about him, and waiting patiently for the desired water before he swallowed the dark brown unsavoury mass of crushed dates which, warm from his pocket and gritty with the sand that penetrated everything, was the only food available. SaÏd was still busy among the throng of men and horses, but near him Omar sat plunged in gloomy silence, his melancholy eyes fixed on the distant hills. He had re-adjusted his robes, screening the ominous stain that revealed what he wished to hide. His hands, which alone might have betrayed the emotion surging under his outward passivity, were concealed in the folds of his enveloping burnous. When the immediate wants of men and horses were assuaged the prevailing clamour gave place to sudden quiet as the Arabs lay down and, muffling their heads in their cloaks, seemed to fall instantly asleep. His supervision ended, SaÏd reappeared, and following the example of his men was soon snoring peacefully. Craven rolled over on his side, and lighting another cigarette settled himself more comfortably on the warm ground. For a time he watched the solitary sentinel sitting motionless on his horse at no great distance from the oasis. Then a vulture winging its slow heavy way across the heavens claimed his attention and he followed it with his eyes until it passed beyond his vision. He was too lazy and too comfortable to turn his head. He lay listening to the shrill hum of countless insect life, smoking cigarette after cigarette till the ground around him was littered with stubs and match ends. The hours passed slowly. When he looked at the guard again the Arab was varying the monotony by walking his horse to and fro, but he had not moved further into the desert. And suddenly as Craven watched him he wheeled and galloped back toward the camp. Craven started up on his arm, screening his eyes from the sun and staring intently in the direction of the hills. But there was nothing to be seen in the wide empty plain, and he sank down again with a smile at his own impatience as the reason of the man's return occurred to him. Reaching the oasis the Arab led his horse among the prostrate sleepers and kicked a comrade into wakefulness to take his place. From time to time the intense stillness was broken by a movement among the horses, and once or twice a vicious scream came from a stallion resenting the attentions of a restless neighbour. The slumbering Arabs lay like sheeted figures of the dead save when some uneasy dreamer rolled over with a smothered grunt into a different position. Craven had begun to wonder how much longer the siesta would be protracted when Omar rose stiffly, and going to his brother's side awoke him with a hand on his shoulder. SaÏd sat up blinking sleepily and then leaped alertly to his feet. In a few minutes the oasis was once more filled with noisy activity. But this time there was no confusion. The men mounted quickly and the troop was reformed with the utmost dispatch. The horses broke almost immediately into the long swinging gallop that seemed to eat up the miles under their feet.

The fiercest heat of the day was passed. The haze that had hung shimmering over the plain had cleared away and the hills they were steadily nearing grew more clearly defined. Soon the conformation of the range was easily discernible, the rocky surface breaking up into innumerable gullies and ravines, the jagged ridges standing out clean against the deep blue of the sky. Another mile and SaÏd turned to him with outstretched hand, pointing eagerly. “See, to the right, there, by that shaft of rock that looks like a minaret, is the entrance to the defile. It is well masked. It comes upon one suddenly. A stranger would hardly find the opening until he was close upon it. In the dawn when the shadows are black I have ridden past it myself once or twice and had to—Allah! Selim—and alone!” he cried suddenly, and shot ahead of his companions. The troop halted at Omar's shouted command, but Craven galloped after his friend. He had caught sight of the horseman emerging from the pass a moment after SaÏd had seen him and the same thought had leaped to the mind of each—the news on which so much depended might still never reach them. The spy came on toward them slowly, his horse reeling under him, and man and beast alike were nearly shot to pieces. As SaÏd drew alongside of them the wounded horse collapsed and the dying man fell with him, unable to extricate himself. In a flash the Arab Chief was on his feet, and with a tremendous effort pulled the dead animal clear of his follower's crushed and quivering limbs. Slipping an arm about him he raised him gently, and bending low to catch the faint words he could scarcely hear, held him until the fluttering whisper trailed into silence, and with a convulsive shudder the man died in his arms.

Laying the corpse back on the sand he wiped his blood-stained hands on the folds of his cloak, then swung into the saddle again and turned to Craven, his eyes blazing with anger and excitement. “They were trapped in the defile—ten against two—but Selim got through somehow to make his reconnaissance, and they finished him off on the way back—though I don't think he left many behind him! Either our plans have been betrayed—or it may be merely a coincidence. Whichever it is they are waiting for us yonder, on the other side of the hills. They have saved us a day's journey—at the very least,” he added with a short laugh that was full of eager anticipation.

They waited until Omar and the troop joined them, and after a short consultation with the headmen it was decided to press forward without delay. Aware that but few hours of daylight remained, Craven deemed it a foolhardy decision, but Omar was deeply stirred at the nearness of the man who had wronged him—for Selim had managed to extract that information from one of his opponents before killing him—and the tribesmen were eager for immediate action. The horses, too, were fresh enough, thanks to the mid-day rest. The troop moved on again, a guard of fifty picked men slightly in advance of the main body.

At the foot of the hills they drew rein to reform for the defile only admitted of three horses walking abreast, and as Craven waited for his own turn to come to enter the narrow pass he looked curiously at the bare rock face that rose almost perpendicularly out of the sand and towered starkly above him. But he had no time for a lengthy inspection, and in a few minutes, with Omar and SaÏd on either hand, he guided his horse round the jutting spur of rock that masked the opening and rode into the sombre shade of the defile. The change was startling, and he shivered with the sudden chill that seemed so much cooler by contrast with the heat of the plain. Hemmed in by sheer sinister looking cliffs, which were broken at intervals by lateral ravines, the tortuous track led over rough slippery ground sprinkled with huge boulders that made any pace beyond a walk impossible. The horses stumbled continually and the necessity of keeping a sharp look-out for each succeeding obstacle drove from Craven's mind everything but the matter in hand. He forgot to wonder how near or how far from the other side of the hills lay the opposing force, or whether they would have time to reform before being attacked or be picked off by waiting marksmen as they emerged from the pass without any possibility of putting up a fight. For himself it didn't after all very much matter one way or the other, but it would be hard luck, he reflected, if Omar did not get a chance at the renegade and SaÏd was shot before the encounter he was aching for—and broke off to swear at his horse, which had stumbled badly for the sixth time.

Omar was riding a pace or two in advance, bending forward in the saddle and occasionally swaying as if from weakness, his burning eyes filled with an almost mystical light as if he saw some vision that, hidden from the others, was revealed to him alone. The dark stain on his robe had spread beyond concealment and he had not spoken since they entered the defile. To Craven, who had never before traversed it, the pass was baffling. He did not know its extent and he had no idea of the depth of the hills. But soon a growing excitement on the part of SaÏd made him aware that the exit must be near and the continued silence argued that the vanguard had got through unmolested. He slipped the button of his holster and freed his revolver from the silk handkerchief in which Yoshio had wrapped it.

A sharp turn to the right revealed the scene of the ambuscade, where in one of the lateral openings Selim and his companion had been trapped. The bodies of men and horses had been pulled clear of the track by the advance guard as they went by a few minutes earlier. The old sheik's horse showed the utmost repugnance to the grim pile of corpses, snorting and rearing dangerously, and Craven wrestled with him for some moments before he bounded suddenly past them with a clatter of hoofs that sent the loose stones flying in all directions.

Another turn to the right, an equally sharp bend to the left, where the track widened considerably, and they debouched abruptly into open desert.

The vanguard was drawn up in order and their leader spurred to Omar's side in eager haste to communicate what was patent to the eyes of all. A little ripple of excitement went through Craven as he saw the dense body of horsemen, still about two miles away, who were galloping steadily towards them. It had come then. With a curious smile he bent forward and patted the neck of his fretting horse, which was fidgeting badly. The opposing force appeared to outnumber them considerably, but he knew from SaÏd that Mukair Ibn Zarrarah's men were better equipped and better trained. It would be skill against brute force, though it yet remained to be seen how far Omar's men would respond to their training when put to the test. Would they be able to control their own headstrong inclinations or would their zeal carry them away in defiance of carefully rehearsed orders?

Word of the near presence of the enemy had been sent back to those who were still moving up the pass, and so far discipline was holding good. The men were pouring out from the yawning mouth of the file in a steady stream, the horses crowded together as closely as possible, and as each detachment arrived it reformed smartly under its own headman.

Watching the rapid approach of the hostile tribe, Craven wondered whether there would be time for their own force to reassemble to enable them to carry out the agreed tactics.

Already they were within half a mile. He had reined back to speak to Omar, when a shout of exultation from SaÏd, taken up by his followers till the rocks above them echoed with the ringing cry, heralded the arrival of the last party. There was no time to recapitulate orders or to urge steadiness among the men. With almost no sign from Omar, or so it seemed to Craven, with another deafening shout that drowned the yelling of the enemy the whole force leaped forward simultaneously. Craven's teeth clenched on his lip in sudden fear for Omar's plan of attack, but a quick glance assured him that the madly galloping horses were being kept in good formation, and that fast as was the pace the right and left wing were, according to instructions, steadily opening out and drawing forward in an extended line. The feeling of excitement had left him, and, revolver in hand, he sat down firmer in the saddle with no more emotion than if he were in the hunting field at home.

They were now close enough to distinguish faces—it would be an almighty crash when it did come! It was surprising that up till now there had been no shooting. Accustomed to the Arabs' usually reckless expenditure of ammunition he had been prepared minutes ago for a hail of bullets. And with the thought came a solitary whining scream past his ear, and SaÏd, close on his left, flung him a look of reproach and shouted something of which he only caught the words, “Frenchman ... burnous.”

But there was no time left to reply. Following rapidly on the single shot a volley was poured in among them, but the shooting was inaccurate and did very little damage. That it had been intended to break the charge and cause confusion in the orderly ranks was apparent from the further repeated volleys that, nearer, did more deadly execution than the first one. But, bending low in their saddles, Mukair Ibn Zarrarah's men swept on in obedience to Omar's command. His purpose was, by the sheer strength of his onset, to cut through the opposing force with his centre while the wings closed in on either side. To effect this he had bidden his men ride as they had never ridden before and reserve their fire till the last moment, when it would be most effectual. And the swift silent onslaught seemed to be other than the enemy had expected, for there were among them signs of hesitation, their advance was checked, and the firing became wilder and more erratic. Omar and his immediate companions appeared to bear charmed lives, bullets sang past them, over and around them, and though here and there a man fell from the saddle or a horse dropped suddenly, the main body raced on unscathed, or with wounds they did not heed in the frenzy of the moment.

The pace was terrific, and when at last Omar gave the signal for which his men were waiting, the crackling reverberation of their rifles had not died away when the impact came. But the shattering crash that Craven had expected did not occur. Giving way before them and scattering to right and left a break came in the ranks of the opposing force, through which they drove like a living wedge. Then with fierce yells of execration the enemy rallied and the next moment Craven found himself in the midst of a confused mÊlÉe where friends and foes were almost indistinguishable. The thundering of horses' hoofs, the raucous shouting of the Arabs, the rattle of musketry, combined in deafening uproar. The air was dense with clouds of sand and smoke, heavy with the reek of powder. He had lost sight of Omar, he tried to keep near to SaÏd, but in the throng of struggling men he was carried away, cut off from his own party, hemmed in on every side, fighting alone. He had forgotten his desire for death, his heart was leaping with a kind of delirious happiness that found nothing but fierce enjoyment in the scene around him. The stench in his nostrils of blood and sulphur seemed to awaken memories of another existence when he had fought for his life as he was doing now, unafraid, and caring little for the outcome. He was shooting steadily, exulting in his markmanship with no thought in his mind but the passionate wish to kill and kill, and he laughed with almost horrible pleasure as he emptied his revolver at the raving Arabs who surrounded him. Drunk with the blood lust of an unremembered past for the moment he was only a savage like them. And to the superstitious desert men he seemed possessed, and with sudden awe they had begun to draw away from him when a further party galloped up to reinforce them. Craven swung his horse to meet the new-comers and at the same moment realised that he had no cartridges left. With another reckless laugh he dashed his empty revolver in the face of the nearest Arab and, wheeling, spurred forward in an attempt to break through the circle round him. But he found retreat cut off. Three men bore down upon him simultaneously with levelled rifles. He saw them fire, felt a sharp searing as of a red hot wire through his side, and, reeling in the saddle, heard dimly their howl of triumph as they raced toward him—heard also another yell that rose above the Arabs' clamour, a piercing yell that sounded strangely different to the Arabic intonation ringing in his ears. And as he gripped himself and raised his head he had a vision of another horseman mounted on a frenzied trampling roan that, apparently out of control and mad with excitement, was charging down upon them, a horseman whose fluttering close-drawn headgear shaded features that were curiously Mongolian—and then he went down in a welter of men and horses. A flying hoof touched the back of his head and consciousness ceased.
