John Silence straightened himself up and drew a long breath. He realised that the performance was temporarily at an end. The collie, meanwhile, who had watched the whole proceeding with marked disapproval, had now lain down again upon the mat by the fire, no longer growling. It seemed to the doctor just as though something that had entered the room while he slept, alarming the dog, yet bringing happiness to the cat, had now gone out again, leaving all as it was before. Whatever it was that excited its blissful attentions had retreated for the moment.
He realised this intuitively. Smoke evidently realised it, too, for presently he deigned to march back to the fireplace and jump upon his master’s knees. Dr. Silence, patient and determined, settled down once more to his book. The animals soon slept; the fire blazed cheerfully; and the cold fog from outside poured into the room through every available chink and crannie.
For a long time silence and peace reigned in the room and Dr. Silence availed himself of the quietness to make careful notes of what had happened. He entered for future use in other cases an exhaustive analysis of what he had observed, especially with regard to the effect upon the two animals. It is impossible here, nor would it be intelligible to the reader unversed in the knowledge of the region known to a scientifically trained psychic like Dr. Silence, to detail these observations. But to him it was clear, up to a certain point—for the rest he must still wait and watch. So far, at least, he realised that while he slept in the chair—that is, while his will was dormant—the room had suffered intrusion from what he recognised as an intensely active Force, and might later be forced to acknowledge as something more than merely a blind force, namely, a distinct personality.
So far it had affected himself scarcely at all, but had acted directly upon the simpler organisms of the animals. It stimulated keenly the centres of the cat’s psychic being, inducing a state of instant happiness (intensifying its consciousness probably in the same way a drug or stimulant intensifies that of a human being); whereas it alarmed the less sensitive dog, causing it to feel a vague apprehension and distress.
His own sudden action and exhibition of energy had served to disperse it temporarily, yet he felt convinced—the indications were not lacking even while he sat there making notes—that it still remained near to him, conditionally if not spatially, and was, as it were, gathering force for a second attack.
And, further, he intuitively understood that the relations between the two animals had undergone a subtle change: that the cat had become immeasurably superior, confident, sure of itself in its own peculiar region, whereas Flame had been weakened by an attack he could not comprehend and knew not how to reply to. Though not yet afraid, he was defiant—ready to act against a fear that he felt to be approaching. He was no longer fatherly and protective towards the cat. Smoke held the key to the situation; and both he and the cat knew it.
Thus, as the minutes passed, John Silence sat and waited, keenly on the alert, wondering how soon the attack would be renewed, and at what point it would be diverted from the animals and directed upon himself.
The book lay on the floor beside him, his notes were complete. With one hand on the cat’s fur, and the dog’s front paws resting against his feet, the three of them dozed comfortably before the hot fire while the night wore on and the silence deepened towards midnight.
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 relight 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 windowpanes, 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 hallway, 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
