It was well after one o'clock in the morning when Dr. Silence turned the lamp out and lighted the candle preparatory to going up to bed. Then Smoke suddenly woke with a loud sharp purr and sat up. It neither stretched, washed nor turned: it listened. And the doctor, watching it, realised that a certain indefinable change had come about that very moment in the room. A swift readjustment of the forces within the four walls had taken place—a new disposition of their personal equations. The balance was destroyed, the former harmony gone. Smoke, most sensitive of barometers, had been the first to feel it, but the dog was not slow to follow suit, for on looking down he noted that Flame was no longer asleep. He was lying with eyes wide open, and that same instant he sat up on his great haunches and began to growl.
Dr. Silence was in the act of taking the matches to re-light the lamp when an audible movement in the room behind him made him pause. Smoke leaped down from his knee and moved forward a few paces across the carpet. Then it stopped and stared fixedly; and the doctor stood up on the rug to watch.
As he rose the sound was repeated, and he discovered that it was not in the room as he first thought, but outside, and that it came from more directions than one. There was a rushing, sweeping noise against the window-panes, and simultaneously a sound of something brushing against the door—out in the hall. Smoke advanced sedately across the carpet, twitching his tail, and sat down within a foot of the door. The influence that had destroyed the harmonious conditions of the room had apparently moved in advance of its cause. Clearly, something was about to happen.
For the first time that night John Silence hesitated; the thought of that dark narrow hall-way, choked with fog, and destitute of human comfort, was unpleasant. He became aware of a faint creeping of his flesh. He knew, of course, that the actual opening of the door was not necessary to the invasion of the room that was about to take place, since neither doors nor windows, nor any other solid barriers could interpose an obstacle to what was seeking entrance. Yet the opening of the door would be significant and symbolic, and he distinctly shrank from it.
But for a moment only. Smoke, turning with a show of impatience, recalled him to his purpose, and he moved past the sitting, watching creature, and deliberately opened the door to its full width.
What subsequently happened, happened in the feeble and flickering light of the solitary candle on the mantlepiece.
Through the opened door he saw the hall, dimly lit and thick with fog. Nothing, of course, was visible—nothing but the hat-stand, the African spears in dark lines upon the wall and the high-backed wooden chair standing grotesquely underneath on the oilcloth floor. For one instant the fog seemed to move and thicken oddly; but he set that down to the score of the imagination. The door had opened upon nothing.
Yet Smoke apparently thought otherwise, and the deep growling of the collie from the mat at the back of the room seemed to confirm his judgment.
For, proud and self-possessed, the cat had again risen to his feet, and having advanced to the door, was now ushering some one slowly into the room. Nothing could have been more evident. He paced from side to side, bowing his little head with great empressement and holding his stiffened tail aloft like a flag-staff. He turned this way and that, mincing to and fro, and showing signs of supreme satisfaction. He was in his element. He welcomed the intrusion, and apparently reckoned that his companions, the doctor and the dog, would welcome it likewise.
The Intruder had returned for a second attack.
Dr. Silence moved slowly backwards and took up his position on the hearthrug, keying himself up to a condition of concentrated attention.
He noted that Flame stood beside him, facing the room, with body motionless, and head moving swiftly from side to side with a curious swaying movement. His eyes were wide open, his back rigid, his neck and jaws thrust forward, his legs tense and ready to leap. Savage, ready for attack or defence, yet dreadfully puzzled and perhaps already a little cowed, he stood and stared, the hair on his spine and sides positively bristling outwards as though a wind played through it. In the dim firelight he looked like a great yellow-haired wolf, silent, eyes shooting dark fire, exceedingly formidable. It was Flame, the terrible.
Smoke, meanwhile, advanced from the door towards the middle of the room, adopting the very slow pace of an invisible companion. A few feet away it stopped and began to smile and blink its eyes. There was something deliberately coaxing in its attitude as it stood there undecided on the carpet, clearly wishing to effect some sort of introduction between the Intruder and its canine friend and ally. It assumed its most winning manners, purring, smiling, looking persuasively from one to the other, and making quick tentative steps first in one direction and then in the other. There had always existed such perfect understanding between them in everything. Surely Flame would appreciate Smoke's intention now, and acquiesce.
But the old collie made no advances. He bared his teeth, lifting his lips till the gums showed, and stood stockstill with fixed eyes and heaving sides. The doctor moved a little farther back, watching intently the smallest movement, and it was just then he divined suddenly from the cat's behaviour and attitude that it was not only a single companion it had ushered into the room, but several. It kept crossing over from one to the other, looking up at each in turn. It sought to win over the dog to friendliness with them all. The original Intruder had come back with reinforcements. And at the same time he further realised that the Intruder was something more than a blindly acting force, impersonal though destructive. It was a Personality, and moreover a great personality. And it was accompanied for the purposes of assistance by a host of other personalities, minor in degree, but similar in kind.
He braced himself in the corner against the mantelpiece and waited, his whole being roused to defence, for he was now fully aware that the attack had spread to include himself as well as the animals, and he must be on the alert. He strained his eyes through the foggy atmosphere, trying in vain to see what the cat and dog saw; but the candlelight threw an uncertain and flickering light across the room and his eyes discerned nothing. On the floor Smoke moved softly in front of him like a black shadow, his eyes gleaming as he turned his head, still trying with many insinuating gestures and much purring to bring about the introductions he desired.
But it was all in vain. Flame stood riveted to one spot, motionless as a figure carved in stone.
Some minutes passed, during which only the cat moved, and then there came a sharp change. Flame began to back towards the wall. He moved his head from side to side as he went, sometimes turning to snap at something almost behind him. They were advancing upon him, trying to surround him. His distress became very marked from now onwards, and it seemed to the doctor that his anger merged into genuine terror and became overwhelmed by it. The savage growl sounded perilously like a whine, and more than once he tried to dive past his master's legs, as though hunting for a way of escape. He was trying to avoid something that everywhere blocked the way.
This terror of the indomitable fighter impressed the doctor enormously; yet also painfully; stirring his impatience; for he had never before seen the dog show signs of giving in, and it distressed him to witness it. He knew, however, that he was not giving in easily, and understood that it was really impossible for him to gauge the animal's sensations properly at all. What Flame felt, and saw, must be terrible indeed to turn him all at once into a coward. He faced something that made him afraid of more than his life merely. The doctor spoke a few quick words of encouragement to him, and stroked the bristling hair. But without much success. The collie seemed already beyond the reach of comfort such as that, and the collapse of the old dog followed indeed very speedily after this.
And Smoke, meanwhile, remained behind, watching the advance, but not joining in it; sitting, pleased and expectant, considering that all was going well and as it wished. It was kneading on the carpet with its front paws—slowly, laboriously, as though its feet were dipped in treacle. The sound its claws made as they caught in the threads was distinctly audible. It was still smiling, blinking, purring.
Suddenly the collie uttered a poignant short bark and leaped heavily to one side. His bared teeth traced a line of whiteness through the gloom. The next instant he dashed past his master's legs, almost upsetting his balance,
