It was evening when Diana opened drowsy and heavy eyes, a bitter taste in her mouth from the effects of the drug that Saint Hubert had given her. Everything had been laid out in readiness for her waking with the little touches that were characteristic of Zilah's handiwork, but the Arab girl herself was not visible. The lamp was lighted, and Diana turned her head languidly, still half confused, to look at the clock beside her. The tiny chime sounded seven times, and with a rush of recollection she leaped up. More than twelve hours since she had knelt beside him after drinking the coffee that Raoul had given her. She guessed what he had done and tried to be grateful, but the thought of what might have happened during the twelve hours she had lain like a log was horrible. She dressed with feverish haste and went into the outer room. It was filled with Arabs, many of whom she did not recognise, and she knew that they must belong to the reinforcements that Ahmed Ben Hassan had sent for. Two, who seemed from their appearance to be petty chiefs, were talking in low tones to Saint Hubert, who looked worn and tired. The rest were grouped silently about the divan, looking at the still-unconscious Sheik. The restlessness and delirium of the morning had passed and been succeeded by a death-like stupor. Nearest to him stood Yusef, his usual swaggering self-assurance changed into an attitude of deepest dejection, and his eyes, that were fixed on Ahmed Ben Hassan's face, were like those of a whipped dog.

Gradually the tent emptied until only Yusef was left, and at last, reluctantly, he too went, stopping at the entrance to speak to Saint Hubert, who had just taken leave of the two headmen.

The Vicomte came back, bringing a chair for Diana, and put her into it with gentle masterfulness. "Sit down," he said almost gruffly. "You look like a ghost."

She looked up at him reproachfully. "You drugged that coffee, Raoul. If he had died to-day while I was asleep I don't think I could ever have forgiven you."

"My dear child," he said gravely, "you don't know how near you were to collapse. If I had not made you sleep I should have had three patients on my hands instead of two."

"I am very ungrateful," she murmured, with a tremulous little smile.

Saint Hubert brought a chair for himself and dropped into it wearily. He felt very tired, the strain of the past twenty-four hours had been tremendous. He had a very real fear that was fast growing into a conviction that his skill was going to prove unequal to save his friend's life, and beside that anxiety and his physical fatigue he had fought a bitter fight with himself all day, tearing out of his heart the envy and jealousy that filled it, and locking away his love as a secret treasure to be hidden for always. His devotion to Ahmed Ben Hassan had survived the greatest test that could be imposed upon it, and had emerged from the trial strengthened and refined, with every trace of self obliterated. It had been the hardest struggle of his life, but it was over now, and all the bitterness had passed, leaving only a passionate desire for Diana's happiness that outweighed every other thought. One spark of comfort remained. He would not be quite useless. His help and sympathy would be necessary to her, and even for that he was grateful.

He looked across the divan at her, and the change that the last few hours had made in her struck him painfully. The alert, vigorous boyishness that had been so characteristic was gone. Her slim figure drooping listlessly in the big chair, her white face with the new marks of suffering on it, and her wide eyes burning with dumb misery, were all purely womanly. And yet though he resented the change he wished it could have gone further. The restraint she was putting on herself was unnatural. She asked no questions and she shed no tears. He could have borne them both easier than the silent anguish of her face. He feared the results of the emotion she was repressing so rigidly.

There was a long silence.

Henri came in once and Diana roused herself to ask for Gaston, and then relapsed into silent watchfulness again. She sighed once, a long quivering sigh that nearly broke Saint Hubert's heart. He rose and bent over the Sheik with his fingers on his wrist, and as he laid the nerveless hand down again she leaned nearer and covered it with her own.

"His hand is so big for an Arab's," she said softly, like a thought spoken aloud unconsciously.

"He is not an Arab," replied Saint Hubert with sudden, impatient vehemence. "He is English."

Diana looked up at him swiftly with utter bewilderment in her startled eyes. "I don't understand," she faltered. "He hates the English."

"Quand-meme, he is the son of one of your English peers. His mother was a Spanish lady; many of the old noble Spanish families have Moorish blood in their veins, the characteristics crop up even after centuries. It is so with Ahmed, and his life in the desert has accentuated it. Has he never told you anything about himself?"

She shook her head. "Sometimes I have wondered——" she said reflectively. "He seemed different from the others, and there has been so much that I could never understand. But then again there were times when he seemed pure Arab," she added in a lower voice and with an involuntary shiver.

"You ought to know," said Saint Hubert. "Yes!" he went on firmly, as she tried to interrupt him. "It is due to you. It will explain so many things. I will take the responsibility. His father is the Earl of Glencaryll."

"But I know him," said Diana wonderingly. "He was a friend of my father. I saw him only a few months ago when Aubrey and I passed through Paris. He is such a magnificent-looking old man, so fierce and sad. Oh, now I know why that awful frown of Ahmed's has always seemed so familiar. Lord Glencaryll frowns like that. It is the famous Caryll scowl. But I still don't understand." She looked from Saint Hubert to the unconscious man on the divan and back to Saint Hubert with a new trouble growing in her eyes.

"I had better tell you the whole story," said Raoul, dropping back into his chair.

"Thirty-six years ago my father, who was as great a wanderer as I am, was staying here in the desert with his friend the Sheik Ahmed Ben Hassan. A chance acquaintance some years before over the purchase of some horses had ripened into a very intimate friendship that was unusual between a Frenchman and an Arab. The Sheik was a wonderful man, very enlightened, with strong European tendencies. As a matter of pure fact he was not too much in sympathy with the French form of administration as carried on in Algeria, but he was not affected sufficiently by it to make any real difficulty. The territory that he regarded as his own lay too much to the south, and he kept his large and scattered tribe in too good order for any interference to be possible. He was unmarried, and the women of his own race seemed to have no attraction for him. He was wrapped up in his tribe and his horses. My father had come for a stay of some months. My mother had recently died and he wanted to get away from everything that reminded him of her. One evening, shortly after his arrival at the camp, a party of the Sheik's men who had been absent for some days in the north on the chief's affairs arrived, bringing with them a woman whom they had found wandering in the desert. How she had got there, or from what direction she had come, they did not know. They were nearer civilisation than Ahmed Ben Hassan's camp at the time, but with true native tendency to avoid responsibility they thought that the disposal of her was a matter more for their Sheik than themselves. She could give no account of herself, as, owing to the effects of the sun or other causes, she was temporarily out of her mind. Arabs are very gentle with any one who is mad—'Allah has touched them!' She was taken to the tent of one of the headmen, whose wife looked after her. For some days it was doubtful whether she would recover, and her condition was aggravated by the fact that she was shortly to become a mother. She did regain her senses after a time, however, but nothing could make her say anything about herself, and questions reduced her to terrible fits of hysterical crying which were prejudicial in her state of health. She seemed calmest when she was left quite alone, but even then she started at the slightest sound, and the headman's wife reported that she would lie for hours on her bed crying quietly to herself. She was quite young—seemingly not more than nineteen or twenty. From her accents my father decided that she was Spanish, but she would admit nothing, not even her nationality. In due course of time the child was born, a boy."

Saint Hubert paused a moment and nodded towards the Sheik. "Even after the child's birth she refused to give any account of herself. In that she was as firm as a rock; in everything else she was the frailest, gentlest little creature imaginable. She was very small and slender, with quantities of soft dark hair and beautiful great dark eyes that looked like a frightened fawn's. I have heard my father describe her many times, and I have seen the water-colour sketch he made of her—he was quite an amateur. Ahmed has it locked away somewhere. She nearly died when the baby was born, and she never recovered her strength. She made no complaint and never spoke of herself, and seemed quite content as long as the child was with her. She was a child herself in a great number of ways. It never seemed to occur to her that there was anything odd in her continued residence in the Sheik's camp. She had a tent and servants of her own, and the headman's wife was devoted to her. So were the rest of the camp for that matter. There was an element of the mysterious in her advent that had taken hold of the superstitious Arabs, and the baby was looked upon as something more than human and was adored by all the tribe. The Sheik himself, who had never looked twice at a woman before in his life, became passionately attached to her. My father says that he has never seen a man so madly in love as Ahmed Ben Hassan was with the strange white girl who had come so oddly into his life. He repeatedly implored her to marry him, and even my father, who has a horror of mixed marriages, was impelled to admit that any woman might have been happy with Ahmed Ben Hassan. She would not consent, though she would give no reason for her refusal, and the mystery that surrounded her remained as insolvable during the two years that she lived after the baby's birth as it had been on the day of her arrival. And her refusal made no difference with the Sheik. His devotion was wonderful. When she died my father was again visiting the camp. She knew that she was dying, and a few days before the end she told them her pitiful little history. She was the only daughter of one of the oldest noble houses in Spain, as poor as they were noble, and she had been married when she was seventeen to Lord Glencaryll, who had seen her with her parents in Nice. She had been married without any regard to her own wishes, and though she grew to love her husband she was always afraid of him. He had a terrible temper that was very easily roused, and, in those days, he also periodically drank a great deal more than was good for him, and when under the influence of drink behaved more like a devil than a man. She was very young and gauche, failing often to do what was required of her from mere nervousness. He was exigent and made no allowance for her youth and inexperience, and her life was one long torture. And yet in spite of it all she loved him. Even in speaking of it she insisted that the fault was hers, that the trouble was due to her stupidity, glossing over his brutality; in fact, it was not from her, but from inquiries that he made after her death, that my father learned most of what her life had been. It seems that Lord Glencaryll had taken her to Algiers and had wished to make a trip into the desert. He had been drinking heavily, and she did not dare to upset his plans by refusing to go with him or even by telling him how soon her child was going to be born. So she went with him, and one night something happened—what she would not say, but my father says he has never seen such a look of terror on any woman's face as she hurried over that part of her story. Whatever it was she waited until the camp was asleep and then slipped out into the desert, mad with fear, with no thought beyond a blind instinct of flight that drove her panic-stricken to face any danger rather than remain and undergo the misery she was flying from. She remembered hurrying onward, terrified by every sound and every shadow, frightened even by the blazing stars that seemed to be watching her and pointing out the way she had taken, until her mind was numb from utter weariness and she remembered nothing more until she awoke in the headman's tent. She had been afraid to say who she was lest she should be sent back to her husband. And with the birth of the child she became more than ever determined to preserve her secret. The boy should be spared the suffering she had herself endured, he should not be allowed to fall into the hands of his father to be at his mercy when the periodical drinking fits made him a very fiend of cruelty. She made my father and the Sheik swear that not until the boy grew to manhood should Lord Glencaryll be told of his existence. She wrote a letter for her husband which she gave into my father's keeping, together with her wedding ring, which had an inscription inside of it, and a miniature of Glencaryll which she had worn always hidden away from sight. She was very contrite with the Sheik, begging his forgiveness for the sorrow she had caused him and for keeping from his knowledge the fact that she was not free. She loved her husband loyally to the end, but the last few days that she lived the Sheik's devotion seemed to wake an answering tenderness in her heart. She was happiest when he was with her, and she died in his arms with his kisses on her lips. She left her boy in his keeping, and Ahmed Ben Hassan adopted him formally and made him his heir, giving him his own name—the hereditary name that the Sheik of the tribe has borne for generations. His word was law amongst his people, and there was no thought of any opposition to his wishes; further, the child was considered lucky, and his choice of successor was received with unanimous delight. All the passionate love that the Sheik had for the mother was transferred to the son. He idolised him, and the boy grew up believing that Ahmed Ben Hassan was his own father. With the traits he had inherited from his mother's people and with his desert upbringing he looked, as he does now, pure Arab. When he was fifteen my father induced the Sheik to send him to Paris to be educated. With his own European tendencies the Sheik had wished it also, but he could not bring himself to part with the boy before, and it was a tremendous wrench to let him go when he did. It was then that I first saw him. I was eighteen at the time, and had just begun my military training, but as my regiment was stationed in Paris I was able to be at home a good deal. He was such a handsome, high-spirited lad. Men mature very young in the desert and in many ways he was a great deal older than I was, in spite of my three years' seniority. But, of course, in other ways he was a perfect child. He had a fiendish temper and resented any check on his natural lawless inclinations. He loathed the restrictions that had to be put upon him and he hated the restraint of town life. He had been accustomed to having his own way in nearly everything, and to the constant adulation of the tribesmen, and he was not prepared to give to anybody else the obedience that he gave willingly to the Sheik. There were some very stormy times, and I never admired my father in anything so much as his handling of that young savage. His escapades were nerve-racking and his beaux yeux led him into endless scrapes. The only threat that reduced him to order was that of sending him home to the Sheik in disgrace. He would promise amendment and take himself off to the Bois to work off his superfluous energy on my father's horses—until he broke out again. But in spite of his temper and his diableries he was very lovable and everybody liked him.

"After a year with us in Paris my father, always mindful of his real nationality, sent him for two years to a tutor in England, where I had myself been. The tutor was an exceptional man, used to dealing with exceptional boys, and Ahmed did very well with him. I don't mean that he did much work—that he evaded skilfully and spent most of his time hunting and shooting. The only thing that he studied at all seriously was veterinary surgery, which he knew would be useful to him with his own horses, and in which his tutor was level-headed enough to encourage him. Then at the end of two years he came back to us for another year. He had gone to the desert every summer for his holidays, and on each occasion the Sheik let him return with greater reluctance. He was always afraid that the call of civilisation would be too much for his adopted son, especially as he grew older, but although Ahmed had changed very much from the wild desert lad who had first come to us, and had developed into a polished man of the world, speaking French and English as fluently as Arabic, with plenty of means to amuse himself in any way that he wished—for the Sheik was very rich and kept him lavishly supplied with money—and though in that last year he was with us he was courted and feted in a way that would have turned most people's heads, he was always secretly longing for the time when he would go back to the desert. It was the desert, not civilisation that called loudest to him. He loved the life and he adored the man whom he thought was his father. To be the son and heir of Ahmed Ben Hassan seemed to him to be the highest pinnacle that any man's ambition could reach. He was perfectly indifferent to the flattery and attention that his money and his good looks brought him. My father entertained very largely and Ahmed became the fashion—'Le bel Arabe' he was called, and he enjoyed a succes fou which bored him to extinction—and at the end of the year, having written to the Sheik for permission to go home, he shook the dust of Paris off his feet and went back to the desert. I went with him. It was my first visit and the first time that I had experienced Ahmed en prince. I had never seen him in anything but European clothes, and I got quite a shock when I came up on deck the morning that we arrived at Oran and found an Arab of the Arabs waiting for me. The robes and a complete change of carriage and expression that seemed to go with them altered him curiously and I hardly recognised him. Some of his men were waiting for him on the quay and their excitement was extraordinary. I realised from the deference and attention that the French officials paid to Ahmed the position that the old Sheik had made for himself and the high esteem in which he was held. We spent the rest of the day in arranging for the considerable baggage that he had brought with him to be forwarded by the camel caravan that had been sent for the purpose, and also in business for the Sheik in Oran. We spent the night in a villa on the outskirts of the town belonging to an old Arab who entertained us lavishly, and who spent the evening congratulating Ahmed heartily on having escaped from the clutches of the odious French, by no means abashed when Ahmed pointed out that there was an odious Frenchman present, for he dismissed me with a gesture that conveyed that my nationality was my misfortune and not my fault, and in impressing on him the necessity of immediately acquiring a wife or two and settling down for the good of the tribe—all this in the intervals of drinking coffee, listening to the most monotonous native music and watching barbaric dances. There was one particularly well-made dancing girl that the old man tried to induce Ahmed to buy, and he made a show of bargaining for her—not from any real interest he took in her, but merely to see the effect that it would have on me. But I refused to be drawn, and as my head was reeling with the atmosphere I escaped to bed and left him still bargaining. We started early next morning, and were joined a few miles out of the town by a big detachment of followers. The excitement of the day before was repeated on a very much larger scale. It was a novel experience for me, and I can hardly describe my feelings in the midst of that yelling horde of men, galloping wildly round us and firing their rifles until it seemed hardly possible that some accident would not happen. It was Ahmed's attitude that impressed me most. He took it all quietly as his due, and when he had had enough of it stopped it with a peremptory authority that was instantly obeyed, and apologised for the exuberant behaviour of his children. It was a new Ahmed to me; the boy I had known for four years seemed suddenly transformed into a man who made me feel very young. In France I had naturally always rather played elder brother, but here Ahmed was on his own ground and the roles seemed likely to be reversed. The arrival at the Sheik's camp was everything that the most lavish scenic producer could have wished. Though I had heard of it both from my father and Ahmed I was not quite prepared for the splendour with which the Sheik surrounded himself. With Eastern luxury was mingled many European adjuncts that added much to the comfort of camp life. The meeting between the Sheik and Ahmed was most touching. I had a very happy time and left with regret. The charm of the desert took hold of me then and has never left me since. But I had to return to my medical studies. I left Ahmed absorbed in his life and happier than I had ever seen him in Paris. He was nineteen then, and when he was twenty-one my father had the unpleasant task of carrying out Lady Glencaryll's dying wishes. He wrote to Lord Glencaryll asking him to come to Paris on business connected with his late wife, and, during the course of a very painful interview, put the whole facts before him. With the letter that the poor girl had written to her husband, with the wedding-ring and the locket, together with the sketch that my father had made of her, the proofs of the genuineness of the whole affair were conclusive. Glencaryll broke down completely. He admitted that his wife had every justification for leaving him, he spared himself nothing. He referred quite frankly to the curse of which he had been the slave and which had made him irresponsible for his actions when he was under its influence. He had never known himself what had happened that terrible night, but the tragedy of his wife's disappearance had cured him. He had made every effort to find her and it was many years before he gave up all hope. He mourned her bitterly, and worshipped her memory. It was impossible not to pity him, for he had expiated his fault with agony that few men can have experienced. The thought that he had a son and that son her child almost overwhelmed him. He had ardently desired an heir, and, thinking himself childless, the fact that his title and his old name, of which he was very proud, would die with him had been a great grief. His happiness in the knowledge of Ahmed's existence was pathetic, he was consumed with impatience for his son's arrival. Nothing had been said to Ahmed in case Lord Glencaryll should prove difficult to convince and thereby complicate matters, but his ready acceptance of the affair and his eagerness to see his son made further delay unnecessary, and my father sent for Ahmed. The old Sheik let him go in ignorance of what was coming. He had always dreaded the time when his adopted son would have to be told of his real parentage, fearful of losing him, jealous of sharing his affection and resenting anybody's claim to him over his own. And so, with the only instance he ever gave of want of moral courage, he sent Ahmed to Paris with no explanation, and left to my father the task of breaking to him the news. I shall never forget that day. It had been arranged that Ahmed should be told first and that afterwards father and son should meet. Ahmed arrived in the morning in time for dejeuner, and afterwards we went to my father's study, and there he told him the whole story as gently and as carefully as he could. Ahmed was standing by the window. He never said a word the whole time my father was speaking, and when he finished he stood quite still for a few moments, his face almost grey under the deep tan, his eyes fixed passionately on my father's—and then his fiendish temper broke out suddenly. It was a terrible scene. He cursed his father in a steady stream of mingled Arabic and French blasphemy that made one's blood run cold. He cursed all English people impartially. He cursed my father because he had dared to send him to England. He cursed me because I had been a party to the affair. The only person whom he spared was the Sheik; who after all was as much implicated as we were, but he never once mentioned him. He refused to see his father, refused to recognise that he was his father, and he left the house that afternoon and Paris that night, going straight back to the desert, taking with him Gaston, who had arranged some time before to enter his service as soon as his time in the cavalry was up. A letter that Lord Glencaryll wrote to him, addressed to Viscount Caryll, which is, of course, his courtesy title, begging for at least an interview, and which he gave to us to forward, was returned unopened, and scrawled across the envelope: 'Inconnu. Ahmed Ben Hassan.' And since that day his hatred of the English had been a monomania, and he has never spoken a word of English. Later on, when we used to travel together, his obvious avoidance of English people was at times both awkward and embarrassing, and I have often had to go through the farce of translating into French or Arabic remarks made to him by English fellow-travellers, that is, when he condescended to notice the remarks, which was not often. From the day he learned the truth about himself for two years we saw nothing of him. Then the old Sheik asked us to visit him. We went with some misgivings as to what Ahmed's reception of us would be, but he met us as if nothing had happened. He ignored the whole episode and has never referred to it. It is a closed incident. The Sheik warned us that Ahmed had told him that any reference to it would mean the breaking off of all relations with us. But Ahmed himself had changed indescribably. All the lovable qualities that had made him so popular in Paris were gone, and he had become the cruel, merciless man he has been ever since. The only love left in him was given to his adopted father, whom he worshipped. Later I was allowed back on the old footing, and he has always been good to Gaston, but with those three exceptions he has spared nobody and nothing. He is my friend, I love him, and I am not telling you more than you know already."

Saint Hubert broke off and looked anxiously at Diana, but she did not move or meet his gaze. She was sitting with her hand still clasped over the Sheik's and the other one shading her face, and the Vicomte went on speaking: "It is so easy to judge, so difficult to understand another person's temptations. Ahmed's position has always been a curious one. He has had unique temptations with always the means of gratifying them."

There was a longer pause, but still Diana did not move or speak.

"The curse of Ishmael had taken hold of me by then and I wandered continually. Sometimes Ahmed came with me; we have shot big game together in most parts of the globe. A few times he stayed with us in Paris, but never for long; he always wearied to get back to the desert. Five years ago the old Sheik died; he was an exceptionally strong man, and should have lived for years but for an accident which crippled him hopelessly and from which he died a few months afterwards. Ahmed's devotion during his illness was wonderful. He never left him, and since he succeeded to the leadership of the tribe he has lived continuously amongst his people, absorbed in them and his horses, carrying on the traditions handed down to him by his predecessor and devoting his life to the tribe. They are like children, excitable, passionate and headstrong, and he has never dared to risk leaving them alone too long, particularly with the menace of Ibraheim Omair always in the background. He has never been able to seek relaxation further afield than Algiers or Oran——" Saint Hubert stopped abruptly, cursing himself for a tactless fool. She could not fail to realise the significance of those visits to the gay, vicious little towns. The inference was obvious. His thoughtless words would only add to her misery. Her sensitive mind would shrink from the contamination they implied. If Ahmed was going to die, she would be desolate enough without forcing on her knowledge the unworthiness of the man she loved. He pushed his chair back impatiently and went to the open doorway. He felt that she wanted to be alone. She watched him go, then slipped to her knees beside the couch.

She had realised the meaning of Raoul's carelessly uttered words and they had hurt her poignantly, but it was no new sorrow. He had told her himself months ago, callously, brutally, sparing her nothing, extenuating nothing. She pressed her cheek against the hand she was holding. She did not blame him, she could only love him, no matter what his life had been. It was Ahmed as he was she loved, his faults, his vices were as much a part of him as his superb physique and the alternating moods that had been so hard to meet. She had never known him otherwise. He seemed to stand alone, outside the prescribed conventions that applied to ordinary men. The standards of common usage did not appear compatible with the wild desert man who was his own law and followed only his own precedent, defiant of social essentials and scornful of criticism. The proud, fierce nature and passionate temper that he had inherited, the position of despotic leadership in which he had been reared, the adulation of his followers and the savage life in the desert, free from all restraint, had combined to produce the haughty unconventionalism that would not submit to the ordinary rules of life. She could not think of him as an Englishman. The mere accident of his parentage was a factor that weighed nothing. He was and always would be an Arab of the wilderness. If he lived! He must live! He could not go out like that, his magnificent strength and fearless courage extinguished by a treacherous blow that had not dared to meet him face to face—in spite of the overwhelming numbers—but had struck him down from behind, a coward stroke. He must live, even if his life meant death to her hopes of happiness; that was nothing compared with his life. She loved him well enough to sacrifice anything for him. If he only lived she could bear even to be put out of his life. It was only he that mattered, his life was everything. He was so young, so strong, so made to live. He had so much to live for. He was essential to his people. They needed him. If she could only die for him. In the days when the world was young the gods were kind, they listened to the prayers of hapless lovers and accepted the life that was offered in place of the beloved whose life was claimed. If God would but listen to her now. If He would but accept her life in exchange for his. If——! if——!

Her fingers crept up lightly across his breast, fearful lest even their tender touch should injure his battered body, and she looked long and earnestly at him. His crisp brown hair was hidden by the bandages that, dead white against his tanned face, swathed his bruised head. His closed eyes with the thick dark lashes curling on his cheek, hiding the usual fierce expression that gleamed in them, and the relaxation of the hard lines of his face made him look singularly young. That youthful look had been noticeable often when he was asleep, and she had watched it wondering what Ahmed the boy had been like before he grew into the merciless man at whose hands she had suffered so much.

And now the knowledge of his boyhood seemed to make him even dearer than he had been before. What sort of man would he have been if the little dark-eyed mother had lived to sway him with her gentleness? Poor little mother, helpless and fragile!—yet strong enough to save her boy from the danger that she feared for him, but paying the price of that strength with her life, content that her child was safe.

Diana thought of her own mother dying in the arms of a husband who adored her, and then of the little Spanish girl slipping away from life, a stranger in a strange land, her heart crying out for the husband whom she still loved, turning in ignorance of his love for consolation in the agony of death to the lover she had denied, and seeking comfort in his arms. A sudden jealousy of the two dead women shook her. They had been loved. Why could not she be loved? Wherein did she fail that he would not love her? Other men had loved her, and his love was all she longed for in the world. To feel his arms around her only once with love in their touch, to see his passionate eyes kindle only once with the light she prayed for. She drew a long sobbing breath. "Ahmed, mon bel Arabe," she murmured yearningly.

She rose to her feet. She was afraid of breaking down, of giving way to the fear and anxiety that racked her. She turned instinctively to the help and sympathy that offered and went to Saint Hubert, joining him under the awning. Usually at night the vicinity of the Sheik's tent was avoided by the tribesmen, even the sentry on guard was posted at some little distance. Kopec curled up outside the doorway kept ample watch. But to-night the open space was swarming with men, some squatting on the ground in circles, others clustered together in earnest conversation, and far off through the palm trees she caught an occasional glimpse of mounted men. Yusef and the headmen acting under him were taking no risks, there was to be no chance of a surprise attack.

"You must be very tired, Raoul," she said, slipping her hand through his arm, for her need was almost as much for physical as mental support. The frank touch of her hand sent a quiver through him, but he suppressed it, and laid his own hand over her cold fingers.

"I must not think of that yet. Later on, perhaps, I can rest a little. Henri can watch; he is almost as good a doctor as I am, the incomparable Henri! Ahmed and I have always quarrelled over the respective merits of our servants."

He felt her hand tighten on his arm at the mention of the Sheik's name and heard the smothered sigh that she choked back. They stood in silence for a while watching the shifting groups of tribesmen. A little knot of low-voiced men near them opened up, and one of their number came to Saint Hubert with an inquiry.

"The men are restless." Raoul said when the Arab had gone back to his fellows with all the consolation the Vicomte could give him. "Their devotion is very strong. Ahmed is a god to them. Their anxiety takes them in a variety of ways. Yusef, who has been occupied with his duties most of the day, has turned to religion for the first time in his life, he has gone to say his prayers with the pious Abdul, as he thinks that Allah is more likely to listen if his petitions go heavenward in company with the holy man's."

Diana's thoughts strayed back to the story that Saint Hubert had told her. "Does Lord Glencaryll know that you see Ahmed?" she asked.

"Oh yes. He and my father became great friends. He often stays with us in Paris. We are a link between him and Ahmed. He is always hungry for any news of him, and still clings to the hope that one day he will relent. He has never made any further effort to open up relations with him because he knows it would be useless. If there is to be any rapprochement between them it must come from Ahmed. They have almost met accidentally once or twice, and Glencaryll has once seen him. It was at the opera. He was staying in Paris for some months and had a box. I had gone across from our own box on the other side of the house to speak to him. There were several people with him. I was standing beside him, talking. Ahmed had just come into our box opposite and was standing right in the front looking over the theatre. Something had annoyed him and he was scowling. The likeness was unmistakable. Glencaryll gave a kind of groan and staggered back against me. 'Good God! Who is that?' he said, and I don't think he knew he was speaking out loud.

"A man next him looked in the direction he was looking and laughed. 'That's the Saint Huberts' wild man of the desert. Looks fierce, doesn't he? The women call him "le bel Arabe." He certainly wears European clothes with better grace than most natives. He is said to have a peculiar hatred of the English, so you'd better give him a wide berth, Glencaryll, if you don't want to be bow-stringed or have your throat cut, or whatever fancy form of death the fellow cultivates in his native habitat. Raoul can tell you all about him.'

"There was not any need for me to tell him. Fortunately the opera began and the lights went down, and I persuaded him to go away before the thing was over."

Diana gave a little shiver. She felt a great sympathy coming over her for the lonely old man, hoping against hope for the impossible, that she had not felt earlier in the evening. He, too, was wearing his heart out against the inflexible will of Ahmed Ben Hassan.

She shivered again and turned back into the tent with Saint Hubert.
They halted by the couch and stood for a long time in silence. Then
Diana slowly raised her head and looked up into Raoul's face, and he
read the agonised question in her eyes.

"I don't know," he said gently. "All things are with Allah."
