nd, 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
realized this, he set it upon the arm of the chair and sprang up with a

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 wa
