adventure; but he did not wish to force its arrival; and he wished to remain normal, and let the animals remain normal, so that, when it came, it would be unattended by excitement or by any straining of the attention. Many experiments had made him wise. And, for the rest, he had no fear.
Accordingly, after a time, he did fall asleep as he had expected, and the last thing he remembered, before oblivion slipped up over his eyes like soft wool, was the picture of Flame stretching all four legs at once, and sighing noisily as he sought a more comfortable position for his paws and muzzle upon the mat.
It was a good deal later when he became aware that a weight lay upon his chest, and that something was pencilling over his face and mouth. A soft touch on the cheek woke him. Something was patting him.
He sat up with a jerk, and found himself staring straight into a pair of brilliant eyes, half green, half black. Smoke’s face lay level with his own; and the cat had climbed up with its front paws upon his chest.
The lamp had burned low and the fire was nearly out, yet Dr. Silence saw in a moment that the cat was in an excited state. It kneaded with its front paws into his chest, shifting from one to the other. He felt them prodding against him. It lifted a leg very carefully and patted his cheek gingerly. Its fur, he saw, was standing ridgewise upon its back; the ears were flattened back somewhat; the tail was switching sharply. The cat, of course, had wakened him with a purpose, and the instant he realised this, he set it upon the arm of the chair and sprang up with a quick turn to face the empty room behind him. By some curious instinct, his arms of their own accord assumed an attitude of defence in front of him, as though to ward off something that threatened his safety. Yet nothing was visible. Only shapes of fog hung about rather heavily in the air, moving slightly to and fro.
His mind was now fully alert, and the last vestiges of sleep gone. He turned the lamp higher and peered about him. Two things he became aware of at once: one, that Smoke, while excited, was pleasurably excited; the other, that the collie was no longer visible upon the mat at his feet. He had crept away to the corner of the wall farthest from the window, and lay watching the room with wide-open eyes, in which lurked plainly something of alarm.
Something in the dog’s behaviour instantly struck Dr. Silence as unusual, and, calling him by name, he moved across to pat him. Flame got up, wagged his tail, and came over slowly to the rug, uttering a low sound that was half growl, half whine. He was evidently perturbed about something, and his master was proceeding to administer comfort when his attention was suddenly drawn to the antics of his other four-footed companion, the cat.
And what he saw filled him with something like amazement.
Smoke had jumped down from the back of the arm-chair and now occupied the middle of the carpet, where, with tail erect and legs stiff as ramrods, it was steadily pacing backwards and forwards in a narrow space, uttering, as it did so, those curious little guttural sounds of pleasure that only an animal of the feline species knows how to make expressive of supreme happiness. Its stiffened legs and arched back made it appear larger than usual, and the black visage wore a smile of beatific joy. Its eyes blazed magnificently; it was in an ecstasy.
At the end of every few paces it turned sharply and stalked back again along the same line, padding softly, and purring like a roll of little muffled drums. It behaved precisely as though it were rubbing against the ankles of some one who remained invisible. A thrill ran down the doctor’s spine as he stood and stared. His experiment was growing interesting at last.
He called the collie’s attention to his friend’s performance to see whether he too was aware of anything standing there upon the carpet; and the dog’s behaviour was significant and corroborative. He came as far as his master’s knees and then stopped dead, refusing to investigate closely. In vain Dr. Silence urged him; he wagged his tail, whined a little, and stood in a half-crouching attitude, staring alternately at the cat and at his master’s face. He was, apparently, both puzzled and alarmed, and the whine went deeper and deeper down into his throat till it changed into an ugly snarl of awakening anger.
Then the doctor called to him in a tone of command he had never known to be disregarded; but still the dog, though springing up in response, declined to move nearer. He made tentative motions, pranced a little like a dog about to take to water, pretended to bark, and ran to and fro on the carpet. So far there was no actual fear in his manner, but he was uneasy and anxious, and nothing would induce him to go within touching distance of the walking cat. Once he made a complete circuit, but always carefully out of reach; and in the end he returned to his master’s legs and rubbed vigorously against him. Flame did not like the performance at all: that much was quite clear.
For several minutes John Silence watched the performance of the cat with profound attention and without interfering. Then he called to the animal by name.
“Smoke, you mysterious beastie, what in the world are you about?” he said, in a coaxing tone.
The cat looked up at him for a moment, smiling in its ecstasy, blinking its eyes, but too happy to pause. He spoke to it again. He called to it several times, and each time it turned upon him its blazing eyes, drunk with inner delight, opening and shutting its lips, its body large and rigid with excitement. Yet it never for one instant paused in its short journeys to and fro.
He noted exactly what it did: it walked, he saw, the same number of paces each time, some six or seven steps, and then it turned sharply and retraced them. By the pattern of the great roses in the carpet he measured it. It kept to the same direction and the same line. It behaved precisely as though it were rubbing against something solid. Undoubtedly, there was something standing there on that strip of carpet, something invisible to the doctor, something that alarmed the dog, yet caused the cat unspeakable pleasure.
“Smokie!” he called again, “Smokie, you black mystery, what is it excites you so?”
Again the cat looked up at him for a brief second, and then continued its sentry-walk, blissfully happy, intensely preoccupied. And, for an instant, as he watched it, the doctor was aware that a faint uneasiness stirred in the depths of his own being, focusing itself for the moment upon this curious behaviour of the uncanny creature before him.
There rose in him quite a new realisation of the mystery connected with the whole feline tribe, but especially with that common member of it, the domestic cat—their hidden lives, their strange aloofness, their incalculable subtlety. How utterly remote from anything that human beings understood lay the sources of their elusive activities. As he watched the indescribable bearing of the little creature mincing along the strip of carpet under his eyes, coquetting with the powers of darkness, welcoming, maybe, some fearsome visitor, there stirred in his heart a feeling strangely akin to awe. Its indifference to human kind, its serene superiority to the obvious, struck him forcibly with fresh meaning; so remote, so inaccessible seemed the secret purposes of its real life, so alien to the blundering honesty of other animals. Its absolute poise of bearing brought into his mind the opium-eater’s words that “no dignity is perfect which does not at some point ally itself with the mysterious”; and he became suddenly aware that the presence of the dog in this foggy, haunted room on the top of Putney Hill was uncommonly welcome to him. He was glad to feel that Flame’s dependable personality was with him. The savage growling at his heels was a pleasant sound. He was glad to hear it. That marching cat made him uneasy.
Finding that Smoke paid no further attention to his words, the doctor decided upon action. Would it rub against his leg, too? He would take it by surprise and see.
He stepped quickly forward and placed himself upon the exact strip of carpet where it walked.
But no cat is ever taken by surprise! The moment he occupied the space of the Intruder, setting his feet on the woven roses midway in the line of travel, Smoke suddenly stopped purring and sat down. It lifted up its face with the most innocent stare imaginable of its green eyes. He could have sworn it laughed. It was a perfect child again. In a single second it had resumed its simple, domestic manner; and it gazed at him in such a way that he almost felt Smoke was the normal being, and his was the eccentric behaviour that was being watched. It was consummate, the manner in which it brought about this change so easily and so quickly.
