"Morphia?" His voice startled her by its harshness. "Don't make a joke of it, Mrs. Carstairs. If I thought you really meant that----"

"But I do--or did." She spoke coolly. "I even went so far as to purchase the means of indulging my fancy."

"You did? But--forgive me--why?"

"Don't we all sigh for oblivion now and then?" She put the question calmly, looking him squarely in the face the while. "I have always understood that morphia is one of the roads into Paradise--a Fool's Paradise, no doubt, but we poor wretches can't always choose our heavens."

"Nor our h.e.l.ls!" He still spoke vehemently. "Yes, there are times in all our lives when oblivion, forgetfulness, seems very desirable, very alluring. But let me entreat you, Mrs. Carstairs, not to seek to enter Paradise by that devil's key!"

Her almond-shaped eyes grew still more narrow as she looked at him.

"I wonder why you speak so impressively," she said slowly. "As a doctor doubtless you are _au fait_ in the subject, yet your vehemence seems to imply----" She paused.

"As a doctor I've seen enough of the havoc the opium fiend plays in the lives of men--and women," he said steadily, "to realize the danger that lies in the insidious habit. I have seen women--women like you"--he had no idea of sparing her--"young, of good position and all the rest of it, who have slid into the deadly thing on the flimsiest of pretexts--and then, too late, have realized they are bound--for life--with fetters which cannot be broken."

"Yet the deadly thing is fascinating, isn't it? Else why do so many fall under its sway?"

"Fascinating?" With an inward shudder Anstice recalled those months after Hilda Ryder's death--those horrible, chaotic months when, in a vain endeavour to stifle thought, to deaden remorse, he had invoked the aid of the poppy, and by so doing had almost precipitated a moral catastrophe which should have been more overwhelming than the first.

"For G.o.d's sake, Mrs. Carstairs, don't become obsessed by that idea. The morphia habit is one degrading slavery of mind and body, and only the miserable victims know how delusive are its promises, how unsatisfactory its rewards. What can you expect from a cult whose highest reward--the only thing, indeed, it has to offer you, is--oblivion?"

Chloe Carstairs did not reply. Instead, she turned away and moved across the room to a small black escritoire which stood against the white wall.

Bending down she opened it, and after pressing a spring, released what appeared to be a secret drawer. From this she lifted out a little packet wrapped in white paper and sealed with red wax, and holding it in her hand she came slowly back to where Anstice stood, made vaguely uncomfortable by her curious, almost secretive manner.

"Dr. Anstice"--she held out the packet--"will you take charge of this for me? It is the key--what you called the devil's key just now--to the Paradise I have never had the courage to enter."

Anstice took the little parcel from her with something of sternness in his face.

"Yes, Mrs. Carstairs. But what, exactly, is this thing?"

"An hypodermic syringe and a supply of morphia," she informed him tranquilly. Then, as he pursed his lips into an involuntary whistle, she went on, with more than a hint of mockery in her manner: "Oh, I came by it quite honestly, I a.s.sure you! I didn't steal it from a doctor's surgery--I bought it at a chemist's shop in London."

"You did?"

"Yes, and I made the young man show me how to use it." She smiled rather ironically. "Naturally I was ignorant in the matter, and I didn't want to make a blunder in its use."

"Really? Well, Mrs. Carstairs, this is your property, but I wish I might persuade you to leave it in my keeping for the present."

"You think it would be safer there?" She looked at him as though considering the matter. "Well, I wonder?"

"You wonder--what?" He spoke dryly.

"Whether it _is_ safer with you. Of course, as a doctor you can get plenty of your own----"

"I shan't be tempted to steal yours for my private use," said Anstice a trifle grimly; and the Fates who rule the lives of men probably smiled to themselves over the fatuity of mankind.

"Well, I gave it to you myself, so you may as well keep it," said Chloe indifferently, as though already tired of the subject; and without more ado Anstice slipped the little white packet into his pocket, and took leave of its former owner before she had opportunity to change her mind on the subject.

He could not dismiss the figure of Chloe Carstairs from his thoughts as he went about his day's work. Intuitively he knew that she was a bitterly unhappy woman, that her life, like his own, had been rent in two by a cataclysm of appalling magnitude, such as visits very few human beings, and he told himself that this woman, too, had been down in the depths even as he had been. And no man, no woman, who has once known the blackness of the abyss, that "outer darkness" in which the soul sits apart in a horror of loneliness, can ever view the world again with quite the clear-eyed vision of the normal human being to whom, fortunately for the sanity of the race, such appalling experiences are mercifully unknown.

On a morning a week later Anstice received a note from Mrs. Carstairs.

"DEAR DR. ANSTICE,"

"My brother has unexpectedly written to offer himself for a couple of nights, and I shall be pleased if you will come to dinner this evening at half-past seven to meet him. I have invited Miss Wayne, so please complete our quartette if you can."

"Sincerely,"

"CHLOE CARSTAIRS."

For some moments Anstice sat inwardly debating the question, the note in his hand.

He had no engagement for the evening. The people of Littlefield, puzzled, perhaps a little piqued, by the aloofness of his manner, rarely invited him to their houses in anything but his professional capacity, though they called upon his services in and out of season; and Sir Richard Wayne and Mr. Carey, the gentle, courtly Vicar of the parish, were the only two men with whom he ever enjoyed an hour's quiet chat over a soothing pipe or cigar.

So that there was no reason why he should hesitate to accept Chloe Carstairs' invitation for that particular evening, yet hesitate he did, unaccountably; and when, after fifteen minutes indecision, he suddenly scribbled and dispatched an acceptance, the messenger had barely gone from his presence before he felt an unreasoning impulse to recall the letter.

What lay at the bottom of his strange reluctance to enjoy Chloe's hospitality he had not the faintest notion. He had no special aversion to meeting her brother, nor was he in any way reluctant to improve his acquaintance with Iris Wayne.... Did his heart, indeed, beat just a shade faster at the thought of meeting her? Yet something seemed to whisper that this invitation was disastrous, that it would set in train events which might be overwhelming in their sequence.

He tried, vainly, to banish the faint premonition of evil which had fallen upon him when he realized it was too late to recall his acceptance. Throughout the day it persisted, and when at length he went to his room to dress for the evening, he felt a strong inclination to excuse himself over the telephone on the plea of an urgent call to whose importance he could not turn a deaf ear.

Such an excuse would, he knew, pa.s.s muster well enough. A doctor can rarely be depended upon, socially, and when he was dressed he went downstairs with the intention of ringing up Cherry Orchard and regretting his inability to make a fourth at Mrs. Carstairs'

dinner-table that night.

Yet at the last moment Fate, or that other Higher Power of which we know too little to speak with any familiarity, intervened to restrain his impulse, and with a muttered imprecation at his own unusual vacillation he turned away from the telephone and went out to his waiting car impatiently.

Arriving at Cherry Orchard, the elderly manservant relieved him of his coat with a deferential smile.

"I think I'm a little late, Hagyard." Anstice glanced at the grandfather clock in the corner. "Or perhaps your clock's a bit forward."

"I daresay it is, sir." Hagyard accepted the suggestion with well-trained alacrity. "Miss Wayne has only been here a moment or two."

He threw open the door as he spoke and Anstice entered the drawing-room with a sudden unwelcome return of his premonition strong upon him.

Yet the room, with its shaded lamps, small wood-fire, and latticed windows open to the sweet spring twilight, looked peaceful enough. As usual there were ma.s.ses of flowers about, tulips, narcissi, anemones; and the atmosphere was fragrant as Anstice went forward to greet his hostess, who stood by one of the cas.e.m.e.nts with her guests beside her.

She came towards him with her usual slow step, which never, for all its deliberation, suggested the languor of ill-health; and as he began to apologize for his late arrival she smiled away his apologies.

"You're not really late, Dr. Anstice, and in any case we should have given you a few minutes' grace."

She stood aside for him to greet Iris, and as he shook hands with the girl Anstice's heart gave a sudden throb of pleasure, which, for the moment, almost succeeded in banishing that uncanny premonition of evil which had come with him to the very gates of Cherry Orchard.

She was very simply dressed in a frock of filmy grey-green chiffon whose colour reminded him of the spiky leaves of a carnation; but he had never seen her look prettier than on that mild spring night; and his eyes unconsciously softened as they dwelt upon her face for one fleeting moment.

Then as Chloe's soft, deep voice, introducing her brother, stole on his ear, he turned to greet the other man; and instantly he realized, too late, the meaning of that presentiment of ill which had haunted him all day; understood why the inner, spiritual part of him had bidden him refuse Chloe Carstairs' invitation to Cherry Orchard that night.

For the man who turned leisurely from the window to greet the new-comer was the man whom he had last seen in a green-walled bedroom in an Indian hotel, the man whom, by a tragic error, he had robbed of the woman he loved, from whom he had parted with a mutual hope that their paths in life might never cross again.

Mrs. Carstairs' brother was the man whom Hilda Ryder had loved, Bruce Cheniston himself.
