"Doctor!" she repeated in an awful whisper. The word meant terror to her. O'Reilly stood amazed. For a second or two neither of them moved.

The woman seemed petrified.

"Dr. Henry, you know," he stammered, finding his tongue again. "I'm in his care. He's in Harley Street."

Her face cleared as suddenly as it had darkened, though the original expression of bewilderment and pain still hung in her great eyes. But the terror left them, as though she suddenly forgot some a.s.sociation that had revived it.

"My home," she murmured. "My home is somewhere here. I'm near it. I must get back--in time--for him. I must. He's coming to me." And with these extraordinary words she turned, walked up the narrow path, and stood upon the porch of a two-storey house before her companion had recovered from his astonishment sufficiently to move or utter a syllable in reply.

The front door, he saw, was ajar. It had been left open.

For five seconds, perhaps for ten, he hesitated; it was the fear that the door would close and shut him out that brought the decision to his will and muscles. He ran up the steps and followed the woman into a dark hall where she had already preceded him, and amid whose blackness she now had finally vanished. He closed the door, not knowing exactly why he did so, and knew at once by an instinctive feeling that the house he now found himself in with this unknown woman was empty and unoccupied.

In a house, however, he felt safe. It was the open streets that were his danger. He stood waiting, listening a moment before he spoke; and he heard the woman moving down the pa.s.sage from door to door, repeating to herself in her low voice of unhappy wailing some words he could not understand:

"Where is it? Oh, where is it? I must get back...."

O'Reilly then found himself abruptly stricken with dumbness, as though, with these strange words, a haunting terror came up and breathed against him in the darkness.

"Is she after all a figure?" ran in letters of fire across his numbed brain. "Is she unreal--or real?"

Seeking relief in action of some kind, he put out a hand automatically, feeling along the wall for an electric switch, and though he found it by some miraculous chance, no answering glow responded to the click.

And the woman's voice from the darkness: "Ah! Ah! At last I've found it.

I'm home again--at last...!" He heard a door open and close upstairs. He was on the ground-floor now--alone. Complete silence followed.

In the conflict of various emotions--fear for himself lest his panic should return, fear for the woman who had led him into this empty house and now deserted him upon some mysterious errand of her own that made him think of madness--in this conflict that held him a moment spell-bound, there was a yet bigger ingredient demanding instant explanation, but an explanation that he could not find. Was the woman real or was she unreal? Was she a human being or a "figure"? The horror of doubt obsessed him with an acute uneasiness that betrayed itself in a return of that unwelcome inner trembling he knew was dangerous.

What saved him from a _crise_ that must have had most dangerous results for his mind and nervous system generally, seems to have been the outstanding fact that he felt more for the woman than for himself. His sympathy and pity had been deeply moved; her voice, her beauty, her anguish and bewilderment, all uncommon, inexplicable, mysterious, formed together a claim that drove self into the background. Added to this was the detail that she had left him, gone to another floor without a word, and now, behind a closed door in a room upstairs, found herself face to face at last with the unknown object of her frantic search--with "it,"

whatever "it" might be. Real or unreal, figure or human being, the overmastering impulse of his being was that he must go to her.

It was this clear impulse that gave him decision and energy to do what he then did. He struck a match, he found a stump of candle, he made his way by means of this flickering light along the pa.s.sage and up the carpetless stairs. He moved cautiously, stealthily, though not knowing why he did so. The house, he now saw, was indeed untenanted; dust-sheets covered the piled-up furniture; he glimpsed through doors ajar, pictures were screened upon the walls, brackets draped to look like hooded heads.

He went on slowly, steadily, moving on tiptoe as though conscious of being watched, noting the well of darkness in the hall below, the grotesque shadows that his movements cast on walls and ceiling. The silence was unpleasant, yet, remembering that the woman was "expecting"

someone, he did not wish it broken. He reached the landing and stood still. Closed doors on both sides of a corridor met his sight, as he shaded the candle to examine the scene. Behind which of these doors, he asked himself, was the woman, figure or human being, now alone with "it"?

There was nothing to guide him, but an instinct that he must not delay sent him forward again upon his search. He tried a door on the right--an empty room, with the furniture hidden by dust-sheets, and the mattress rolled up on the bed. He tried a second door, leaving the first one open behind him, and it was, similarly, an empty bedroom. Coming out into the corridor again he stood a moment waiting, then called aloud in a low voice that yet woke echoes unpleasantly in the hall below: "Where are you? I want to help--which room are you in?"

There was no answer; he was almost glad he heard no sound, for he knew quite well that he was waiting really for another sound--the steps of him who was "expected." And the idea of meeting with this unknown third sent a shudder through him, as though related to an interview he dreaded with his whole heart, and must at all costs avoid. Waiting another moment or two, he noted that his candle-stump was burning low, then crossed the landing with a feeling, at once of hesitation and determination, towards a door opposite to him. He opened it; he did not halt on the threshold. Holding the candle at arm's length, he went boldly in.

And instantly his nostrils told him he was right at last, for a whiff of the strange perfume, though this time much stronger than before, greeted him, sending a new quiver along his nerves. He knew now why it was a.s.sociated with unpleasantness, with pain, with misery, for he recognized it--the odour of a hospital. In this room a powerful anaesthetic had been used--and recently.

Simultaneously with smell, sight brought its message too. On the large double bed behind the door on his right lay, to his amazement, the woman in the dark fur coat. He saw the jewels on the slender neck; but the eyes he did not see, for they were closed--closed, too, he grasped at once, in death. The body lay stretched at full length, quite motionless.

He approached. A dark thin streak that came from the parted lips and pa.s.sed downwards over the chin, losing itself then in the fur collar, was a trickle of blood. It was hardly dry. It glistened.

Strange it was perhaps that, while imaginary fears had the power to paralyse him, mind and body, this sight of something real had the effect of restoring confidence. The sight of blood and death, amid conditions often ghastly and even monstrous, was no new thing to him. He went up quietly, and with steady hand he felt the woman's cheek, the warmth of recent life still in its softness. The final cold had not yet mastered this empty form whose beauty, in its perfect stillness, had taken on the new strange sweetness of an unearthly bloom. Pallid, silent, untenanted, it lay before him, lit by the flicker of his guttering candle. He lifted the fur coat to feel for the unbeating heart. A couple of hours ago at most, he judged, this heart was working busily, the breath came through those parted lips, the eyes were shining in full beauty. His hand encountered a hard k.n.o.b--the head of a long steel hat-pin driven through the heart up to its hilt.

He knew then which was the figure--which was the real and which the unreal. He knew also what had been meant by "it."

But before he could think or reflect what action he must take, before he could straighten himself even from his bent position over the body on the bed, there sounded through the empty house below the loud clang of the front door being closed. And instantly rushed over him that other fear he had so long forgotten--fear for himself. The panic of his own shaken nerves descended with irresistible onslaught. He turned, extinguishing the candle in the violent trembling of his hand, and tore headlong from the room.

The following ten minutes seemed a nightmare in which he was not master of himself and knew not exactly what he did. All he realized was that steps already sounded on the stairs, coming quickly nearer. The flicker of an electric torch played on the banisters, whose shadows ran swiftly sideways along the wall as the hand that held the light ascended. He thought in a frenzied second of police, of his presence in the house, of the murdered woman. It was a sinister combination. Whatever happened, he must escape without being so much as even seen. His heart raced madly.

He darted across the landing into the room opposite, whose door he had luckily left open. And by some incredible chance, apparently, he was neither seen nor heard by the man who, a moment later, reached the landing, entered the room where the body of the woman lay, and closed the door carefully behind him.

Shaking, scarcely daring to breathe lest his breath be audible, O'Reilly, in the grip of his own personal terror, remnant of his uncured shock of war, had no thought of what duty might demand or not demand of him. He thought only of himself. He realized one clear issue--that he must get out of the house without being heard or seen. Who the new-comer was he did not know, beyond an uncanny a.s.surance that it was _not_ him whom the woman had "expected," but the murderer himself, and that it was the murderer, in his turn, who was expecting this third person. In that room with death at his elbow, a death he had himself brought about but an hour or two ago, the murderer now hid in waiting for his second victim. And the door was closed.

Yet any minute it might open again, cutting off retreat.

O'Reilly crept out, stole across the landing, reached the head of the stairs, and began, with the utmost caution, the perilous descent.

Each time the bare boards creaked beneath his weight, no matter how stealthily this weight was adjusted, his heart missed a beat. He tested each step before he pressed upon it, distributing as much of his weight as he dared upon the banisters. It was a little more than half-way down that, to his horror, his foot caught in a projecting carpet tack; he slipped on the polished wood, and only saved himself from falling headlong by a wild clutch at the railing, making an uproar that seemed to him like the explosion of a hand-grenade in the forgotten trenches.

His nerves gave way then, and panic seized him. In the silence that followed the resounding echoes he heard the bedroom door opening on the floor above.

Concealment was now useless. It was impossible, too. He took the last flight of stairs in a series of leaps, four steps at a time, reached the hall, flew across it, and opened the front door, just as his pursuer, electric torch in hand, covered half the stairs behind him. Slamming the door, he plunged headlong into the welcome, all-obscuring fog outside.

The fog had now no terrors for him, he welcomed its concealing mantle; nor did it matter in which direction he ran so long as he put distance between him and the house of death. The pursuer had, of course, not followed him into the street. He crossed open s.p.a.ces without a tremor.

He ran in a circle nevertheless, though without being aware he did so.

No people were about, no single groping shadow pa.s.sed him; no boom of traffic reached his ears, when he paused for breath at length against an area railing. Then for the first time he made the discovery that he had no hat. He remembered now. In examining the body, partly out of respect, partly perhaps unconsciously, he had taken it off and laid it--on the very bed.

It was there, a tell-tale bit of d.a.m.ning evidence, in the house of death. And a series of probable consequences flashed through his mind like lightning. It was a new hat fortunately; more fortunate still, he had not yet written name or initials in it; but the maker's mark was there for all to read, and the police would go immediately to the shop where he had bought it only two days before. Would the shop-people remember his appearance? Would his visit, the date, the conversation be recalled? He thought it was unlikely; he resembled dozens of men; he had no outstanding peculiarity. He tried to think, but his mind was confused and troubled, his heart was beating dreadfully, he felt desperately ill.

He sought vainly for some story to account for his being out in the fog and far from home without a hat. No single idea presented itself. He clung to the icy railings, hardly able to keep upright, collapse very near--when suddenly a figure emerged from the fog, paused a moment to stare at him, put out a hand and caught him, and then spoke:

"You're ill, my dear sir," said a man's kindly voice. "Can I be of any a.s.sistance? Come, let me help you." He had seen at once that it was not a case of drunkenness. "Come, take my arm, won't you? I'm a physician.

Luckily, too, you are just outside my very house. Come in." And he half dragged, half pushed O'Reilly, now bordering on collapse, up the steps and opened the door with his latch-key.

"Felt ill suddenly--lost in the fog ... terrified, but be all right soon, thanks awfully----" the Canadian stammered his grat.i.tude, but already feeling better. He sank into a chair in the hall, while the other put down a paper parcel he had been carrying, and led him presently into a comfortable room; a fire burned brightly; the electric lamps were pleasantly shaded; a decanter of whisky and a siphon stood on a small table beside a big arm-chair; and before O'Reilly could find another word to say the other had poured him out a gla.s.s and bade him sip it slowly, without troubling to talk till he felt better.

"That will revive you. Better drink it slowly. You should never have been out a night like this. If you've far to go, better let me put you up----"

"Very kind, very kind, indeed," mumbled O'Reilly, recovering rapidly in the comfort of a presence he already liked and felt even drawn to.

"No trouble at all," returned the doctor. "I've been at the front, you know. I can see what your trouble is--sh.e.l.l-shock, I'll be bound."

The Canadian, much impressed by the other's quick diagnosis, noted also his tact and kindness. He had made no reference to the absence of a hat, for instance.

"Quite true," he said. "I'm with Dr. Henry, in Harley Street," and he added a few words about his case. The whisky worked its effect, he revived more and more, feeling better every minute. The other handed him a cigarette; they began to talk about his symptoms and recovery; confidence returned in a measure, though he still felt badly frightened.

The doctor's manner and personality did much to help, for there was strength and gentleness in the face, though the features showed unusual determination, softened occasionally by a sudden hint as of suffering in the bright, compelling eyes. It was the face, thought O'Reilly, of a man who had seen much and probably been through h.e.l.l, but of a man who was simple, good, sincere. Yet not a man to trifle with; behind his gentleness lay something very stern. This effect of character and personality woke the other's respect in addition to his grat.i.tude. His sympathy was stirred.

"You encourage me to make another guess," the man was saying, after a successful reading of the impromptu patient's state, "that you have had, namely, a severe shock quite recently, and"--he hesitated for the merest fraction of a second--"that it would be a relief to you," he went on, the skilful suggestion in the voice unnoticed by his companion, "it would be wise as well, if you could unburden yourself to--someone--who would understand." He looked at O'Reilly with a kindly and very pleasant smile. "Am I not right, perhaps?" he asked in his gentle tone.

"Someone who would understand," repeated the Canadian. "That's my trouble exactly. You've hit it. It's all so incredible."

The other smiled. "The more incredible," he suggested, "the greater your need for expression. Suppression, as you may know, is dangerous in cases like this. You think you have hidden it, but it bides its time and comes up later, causing a lot of trouble. Confession, you know"--he emphasized the word--"confession is good for the soul!"

"You're dead right," agreed the other.

"Now if you can, bring yourself to tell it to someone who will listen and believe--to myself, for instance. I am a doctor, familiar with such things. I shall regard all you say as a professional confidence, of course; and, as we are strangers, my belief or disbelief is of no particular consequence. I may tell you in advance of your story, however--I think I can promise it--that I shall believe all you have to say."

O'Reilly told his story without more ado, for the suggestion of the skilled physician had found easy soil to work in. During the recital his host's eyes never once left his own. He moved no single muscle of his body. His interest seemed intense.

"A bit tall, isn't it?" said the Canadian, when his tale was finished.

"And the question is----" he continued with a threat of volubility which the other checked instantly.
