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, and shot out into the room, where he went blundering wildly against walls and furniture. But that bark was significant; the doctor had heard it before and knew what it meant: for it was the cry of the fighter against odds and it meant that the old beast had found his courage again. Possibly it was only the courage of despair, but at any rate the fighting would be terrific. And Dr. Silence understood, too, that he dared not interfere. Flame must fight his own enemies in his own way.
But the cat, too, had heard that dreadful bark; and it, too, had understood. This was more than it had bargained for. Across the dim shadows of that haunted room there must have passed some secret signal of distress between the animals. Smoke stood up and looked swiftly about him. He uttered a piteous meow and trotted smartly away into the greater darkness by the windows. What his object was only those endowed with the spirit-like intelligence of cats might know. But, at any rate, he had at last ranged himself on the side of his friend. And the little beast meant business.
At the same moment the collie managed to gain the door. The doctor saw him rush through into the hall like a flash of yellow light. He shot across the oilcloth, and tore up the stairs, but in another second he appeared again, flying down the steps and landing at the bottom in a tumbling heap, whining, cringing, terrified. The doctor saw him slink back into the room again and crawl round by the wall towards the cat. Was, then, even the staircase occupied? Did They stand also in the hall? Was the whole house crowded from floor to ceiling?
The thought came to add to the keen distress he felt at the sight of the collie's discomfiture. And, indeed, his own personal distress had increased in a marked degree during the past minutes, and continued to increase steadily to the climax. He recognised that the drain on his own vitality
