The parting of Mr. and Mrs. Greyne on the following morning was very affecting. It took place at Victoria Station, in the midst of a small crowd of admiring strangers, who had recognised the commanding presence of the great novelist, and had gathered round to observe her manifestations.

Mrs. Greyne was considerably shaken by the event of the previous night. Although, on the discovery of the diary, the house had been roused, and all the servants closely questioned, no light had been thrown upon its migration from the locked drawer to the schoolroom table. Adolphus and Olivia, jerked from sleep by the hasty hands of a maid, could only weep and wan. The powdered footmen, one and all, declared they had never heard of a diary. The butler gave warning on the spot, keeping on his nightcap to give greater effect to his pronunciamento. It was all most unsatisfactory, and for one wild moment Mrs. Greyne seriously thought of retaining her husband by her as a protection against the mysterious thief who had been at work in their midst. Could it be Mademoiselle Verbena? The dread surmise occurred, but Mr. Greyne rejected it.

“Her father was a count,” he said. “Besides, my darling, I don’t believe she can read English; certainly not unless it is printed.”

So there the matter rested, and the moment of parting came.

There was a murmur of respectful sympathy as Mrs. Greyne clasped her husband tenderly in her arms, and pressed his head against her prune-coloured bonnet strings. The whistle sounded. The train moved on. Leaning from a reserved first-class compartment, Mr. Greyne waved a silk pocket-handkerchief so long as his wife’s Roman profile stood out clear against the fog and smoke of London. But at last it faded, grew remote, took on the appearance of a feebly-executed crayon drawing, vanished. He sank back upon the cushions—alone. Darrell was travelling second with the dressing-case.

It was a strange sensation, to be alone, and en route to Algiers. Mr. Greyne scarcely knew what to make of it. A schoolboy suddenly despatched to Timbuctoo could hardly have felt more terribly emancipated than he did. He was so absolutely unaccustomed to freedom, he had been for so long without the faintest desire for it, that to have it thrust upon him so suddenly was almost alarming. He felt lonely, anxious, horribly unmarried. To divert his thoughts he drew forth a Merrin’s exercise-book and a pencil, and wrote on the first page, in large letters, “African Frailty, Notes for” Then he sat gazing at the title of his first literary work, and wondering what on earth he was going to see in Algiers.

Vague visions of himself in the bars of African public-houses, in mosques, in the two-pair-backs of dervishes, in bazaars—which he pictured to himself like those opened by royalties at the Queen’s Hall—in Moorish interiors surrounded by voluptuous ladies with large oval eyes, black tresses, and Turkish trousers of spangled muslin, flitted before his mental gaze. When the train ran upon Dover Pier, and the white horses of the turbulent Channel foamed at his feet, he started as one roused from a Rip Van Winkle sleep. Severe illness occupied his whole attention for a time, and then recovery.

In Paris he dined at the buffet like one in a dream, and, at the appointed hour, came forth to take the rapide for Marseilles. He looked for Darrell and the dressing-case. They were not to be seen. There stood the train. Passengers were mounting into it. Old ladies with agitated faces were buying pillows and nibbling biscuits. Elderly gentlemen with yellow countenances and red ribands in their coats were purchasing the Figaro and the Gil Blas. Children with bare legs were being hauled into compartments. Rook’s agent was explaining to a muddled tourist in a tam-o’-shanter the exact difference between the words “Oui” and “Non” The bustle of departure was in the air, but Darrell was not to be seen. Mr. Greyne had left him upon the platform with minute directions as to the point from which the train would start and the hour of its going. Yet he had vanished. The most frantic search, the most frenzied inquiries of officials and total strangers, failed to elicit his whereabouts, and, finally, Mr. Greyne was flung forcibly upward into the wagonlit, and caught by the contrÔleur when the train was actually moving out of the station.

A moment later he fell exhausted upon the pink-plush seat of his compartment, realising his terrible position. He was now utterly alone; without servant, hair-brushes, toothbrushes, razors, sponges, pajamas, shoes. It was a solitude that might be felt. He thought of the sea journey with no kindly hand to minister to him, the arrival in Africa with no humble companion at his side, to wonder with him at the black inhabitants and help him through the customs—to say nothing of the manners. He thought of the dread homes of iniquity into which he must penetrate by night in search of the material for the voracious “Catherine.” He had meant to take Darrell with him to them all—Darrell, whose joyful delight in the prospect of exploring the Eastern fastnesses of crime had been so boyish, so truly English in its frank, its even boisterous sincerity.

And now he was utterly alone, almost like Robinson Crusoe.

The contrÔleur came in to make the bed. Mr. Greyne told him the dreadful story.

“No doubt he has been lured away, monsieur. The dressing-case was of value?”

“Crocodile, gold fittings.”

“Probably monsieur will never see him again. As likely as not he will sleep in the Seine to-night, and at the morgue to-morrow.”

Mr. Greyne shuddered. This was an ill omen for his expedition. He drank a stiff whisky-and-soda instead of the usual barley water, and went to bed to dream of bloody murders in which he was the victim.

When the train ran into Marseilles next morning he was an unshaven, miserable man.

“Have I time to buy a tooth-brush,” he inquired anxiously at the station, “before the boat sails for Algiers?”

The chef de gare thought so. Monsieur had four hours, if that was sufficient. Mr. Greyne hastened forth, had a Turkish bath, purchased a new dressing-case, ate a hasty dÉjeuner, and took a cab to the wharf. It was a long drive over the stony streets. He glanced from side to side, watching the bustling traffic, the hurry of the nations going to and from the ships. His eyes rested upon two Arabs who were striding along in his direction. Doubtless they were also bound for Algiers. He thought they looked most wicked, and hastily took a note of them for “African Frailty.” Beside his sense of loss and loneliness marched the sense of duty. The great woman at home in Belgrave Square, founder of his fortunes, mother of his children, she depended upon him. Even in his own hour of need he would not fail her. He took a lead pencil, and wrote down:

Saw two Arab ruffians. Bare legs. Look capable of anything. Should not be surprised to hear that they had——

There he paused. That they had what? Done things. Of course, but what things? That was the question. He exerted his imagination, but failed to arrive at any conclusion as to their probable crimes. His knowledge of wickedness was really absurdly limited. For the first time he felt slightly ashamed of it, and began to wish he had gone into the militia. He comforted himself with the thought that in a fortnight he would probably be fit for the regular army. This thought cheered him slightly, and it was with a slight smile upon his face that he welcomed the first glimpse of the GÉnÉral Bertrand, which was lying against the quay ready to cast off at the stroke of noon. Most of the passengers were aboard, but, as Mr. Greyne stepped out of his cab, and prepared to pay the Maltese driver, a trim little lady, plainly dressed in black, and carrying a tiny and rather coquettish hand-bag, was tripping lightly across the gangway. Mr. Greyne glanced at her as he turned to follow, glanced, and then started. That back was surely familiar to him. Where could he have seen it before? He searched his memory as the little lady vanished. It was a smart, even a chic back, a back that knew how to take care of itself, a back that need not go through the world alone, a back, in fine, that was most distinctly attractive, if not absolutely alluring. Where had he seen it before, or had he ever seen it at all? He thought of his wife’s back, flat, powerful, uncompromising. This was very different, more—how should he put it to himself?—more Algerian, perhaps. He could vaguely conceive it a back such as one might meet with while engaged in adding to one’s stock of knowledge of—well—African frailty.

At this moment the steward appeared to show him to his cabin, and his further reflections were mainly connected with the Gulf of Lyons.

Twilight was beginning to fall when, so far as he was capable of thinking, he thought he would like a breath of air. For some moments he lay quite still, dwelling on this idea which had so mysteriously come to him. Then he got up, and thought again, seated upon the cabin floor. He knew there was a deck. He remembered having seen one when he came aboard. He put on his fur coat, still sitting on the cabin floor. The process took some time—he fancied about a couple of years. At last, however, it was completed, and he rose to his feet with the assistance of the washstand and the berth.

The ship seemed very busy, full of almost American activity. He thought a greater calm would have been more decent, and waited in the hope that the floor would presently cease to forget itself. As it showed no symptoms of complying with his desire he endeavoured to spurn it, and, in the fulness of time, gained the companion.

It was very strange, as he remembered afterwards, that only when he had gained the companion did the sense of his utter loneliness rush upon him with overwhelming force: one of the ironies of life, he supposed. Eventually he shook the companion off with a good deal of difficulty, and found himself installed upon planks under a grey sky, and holding fast to a railing, which was all that interposed between him and eternity.

At first he was only conscious of greyness and the noise of winds and waters, but presently a black daub seemed to hover for a second somewhere on the verge of his world, to hover and disappear. He wondered what it was. A smut, perhaps. He rubbed his face. The daub returned. It was very large for a smut. He strove to locate it, and found that it must be somewhere on his left cheek. With a great effort he took out his pocket-handkerchief. Suddenly the daub assumed monstrous proportions. He turned his head, and perceived the lady in black whom he had seen tripping over the gangway on his arrival.

She was a few steps from him, leaning upon the rail in an attitude of the deepest dejection, with her face averted; yet it struck him that her right shoulder was oddly familiar, as her back had surely been. The turn of her head, too—he coughed despairingly. The lady took no notice. He coughed again. Interest was quickening in him. He was determined to see the lady’s face.

This time she looked around, showing a pale countenance bedewed with tears, and totally devoid of any expression which he could connect with a consciousness of his presence. For a moment she stared vacantly at him, while he, with almost equal vacancy, regarded her. Then a thrill of surprise shook him. A sudden light of knowledge leaped up in him, and he exclaimed:

“Mademoiselle Verbena!” “Monsieur?” murmured the lady, with an accent of surprise.

“Mademoiselle Verbena! Surely it is—it must be!”

He had staggered sideways, nearing her.

“Mademoiselle Verbena, do you not know me? It is I, Eustace Greyne, the father of your pupils, the husband of Mrs. Eustace Greyne?”

An expression of stark amazement came into the lady’s face at these words. She leaned forward till her eyes were close to Mr. Greyne’s then gave a little cry.

“Mon Dieu! It is true! You are so altered that I could not recognise. And then—what are you doing here, on the wide sea, far from madame?”

“I was just about to ask you the very same question!” cried Mr. Greyne.
