After an uneventful search they came down again to the study, and here Dr. Silence discovered Smoke washing his face calmly in front of the fire. The saucer of milk was licked dry and clean; the preliminary examination that cats always make in new surroundings had evidently been satisfactorily concluded. He drew an arm-chair up to the fire, stirred the coals into a blaze, arranged the table and lamp to his satisfaction for reading, and then prepared surreptitiously to watch the animals. He wished to observe them carefully without their being aware of it.
Now, in spite of their respective ages, it was the regular custom of these two to play together every night before sleep. Smoke always made the advances, beginning with grave impudence to pat the dog’s tail, and Flame played cumbrously, with condescension. It was his duty, rather than pleasure; he was glad when it was over, and sometimes he was very determined and refused to play at all.
And this night was one of the occasions on which he was firm.
The doctor, looking cautiously over the top of his book, watched the cat begin the performance. It started by gazing with an innocent expression at the dog where he lay with nose on paws and eyes wide open in the middle of the floor. Then it got up and made as though it meant to walk to the door, going deliberately and very softly. Flame’s eyes followed it until it was beyond the range of sight, and then the cat turned sharply and began patting his tail tentatively with one paw. The tail moved slightly in reply, and Smoke changed paws and tapped it again. The dog, however, did not rise to play as was his wont, and the cat fell to patting it briskly with both paws. Flame still lay motionless.
This puzzled and bored the cat, and it went round and stared hard into its friend’s face to see what was the matter. Perhaps some inarticulate message flashed from the dog’s eyes into its own little brain, making it understand that the programme for the night had better not begin with play. Perhaps it only realised that its friend was immovable. But, whatever the reason, its usual persistence thenceforward deserted it, and it made no further attempts at persuasion. Smoke yielded at once to the dog’s mood; it sat down where it was and began to wash.
But the washing, the doctor noted, was by no means its real purpose; it only used it to mask something else; it stopped at the most busy and furious moments and began to stare about the room. Its thoughts wandered absurdly. It peered intently at the curtains; at the shadowy corners; at empty space above; leaving its body in curiously awkward positions for whole minutes together. Then it turned sharply and stared with a sudden signal of intelligence at the dog, and Flame at once rose somewhat stiffly to his feet and began to wander aimlessly and restlessly to and fro about the floor. Smoke followed him, padding quietly at his heels. Between them they made what seemed to be a deliberate search of the room.
And, here, as he watched them, noting carefully every detail of the performance over the top of his book, yet making no effort to interfere, it seemed to the doctor that the first beginnings of a faint distress betrayed themselves in the collie, and in the cat the stirrings of a vague excitement.
He observed them closely. The fog was thick in the air, and the tobacco smoke from his pipe added to its density; the furniture at the far end stood mistily, and where the shadows congregated in hanging clouds under the ceiling, it was difficult to see clearly at all; the lamplight only reached to a level of five feet from the floor, above which came layers of comparative darkness, so that the room appeared twice as lofty as it actually was. By means of the lamp and the fire, however, the carpet was everywhere clearly visible.
The animals made their silent tour of the floor, sometimes the dog leading, sometimes the cat; occasionally they looked at one another as though exchanging signals; and once or twice, in spite of the limited space, he lost sight of one or other among the fog and the shadows. Their curiosity, it appeared to him, was something more than the excitement lurking in the unknown territory of a strange room; yet, so far, it was impossible to test this, and he purposely kept his mind quietly receptive lest the smallest mental excitement on his part should communicate itself to the animals and thus destroy the value of their independent behaviour.
They made a very thorough journey, leaving no piece of furniture unexamined, or unsmelt. Flame led the way, walking slowly with lowered head, and Smoke followed demurely at his heels, making a transparent pretence of not being interested, yet missing nothing. And, at length, they returned, the old collie first, and came to rest on the mat before the fire. Flame rested his muzzle on his master’s knee, smiling beatifically while he patted the yellow head and spoke his name; and Smoke, coming a little later, pretending he came by chance, looked from the empty saucer to his face, lapped up the milk when it was given him to the last drop, and then sprang upon his knees and curled round for the sleep it had fully earned and intended to enjoy.
Silence descended upon the room. Only the breathing of the dog upon the mat came through the deep stillness, like the pulse of time marking the minutes; and the steady drip, drip of the fog outside upon the window-ledges dismally testified to the inclemency of the night beyond. And the soft crashings of the coals as the fire settled down into the grate became less and less audible as the fire sank and the flames resigned their fierceness.
It was now well after eleven o’clock, and Dr. Silence devoted himself again to his book. He read the words on the printed page and took in their meaning superficially, yet without starting into life the correlations of thought and suggestion that should accompany interesting reading. Underneath, all the while, his mental energies were absorbed in watching, listening, waiting for what might come. He was not over sanguine himself, yet he did not wish to be taken by surprise. Moreover, the animals, his sensitive barometers, had incontinently gone to sleep.
After reading a dozen pages, however, he realised that his mind was really occupied in reviewing the features of Pender’s extraordinary story, and that it was no longer necessary to steady his imagination by studying the dull paragraphs detailed in the pages before him. He laid down his book accordingly, and allowed his thoughts to dwell upon the features of the Case. Speculations as to the meaning, however, he rigorously suppressed, knowing that such thoughts would act upon his imagination like wind upon the glowing embers of a fire.
As the night wore on the silence grew deeper and deeper, and only at rare intervals he heard the sound of wheels on the main road a hundred yards away, where the horses went at a walking pace owing to the density of the fog. The echo of pedestrian footsteps no longer reached him, the clamour of occasional voices no longer came down the side street The night, muffled by fog, shrouded by veils of ultimate mystery, hung about the haunted villa like a doom. Nothing in the house stirred. Stillness, in a thick blanket, lay over the upper storeys. Only the mist in the room grew more dense, he thought, and the damp cold more penetrating. Certainly, from time to time, he shivered.
The collie, now deep in slumber, moved occasionally—grunted, sighed, or twitched his legs in dreams. Smoke lay on his knees, a pool of warm, black fur, only the closest observation detecting the movement of his sleek sides. It was difficult to distinguish exactly where his head and body joined in that circle of glistening hair; only a black satin nose and a tiny tip of pink tongue betrayed the secret.
Dr. Silence watched him, and felt comfortable. The collie’s breathing was soothing. The fire was well built, and would burn for another two hours without attention. He was not conscious of the least nervousness. He particularly wished to remain in his ordinary and normal state of mind, and to force nothing. If sleep came naturally, he would let it come—and even welcome it. The coldness of the room, when the fire died down later, would be sure to wake him again; and it would then be time enough to carry these sleeping barometers up to bed. From various psychic premonitions he knew quite
