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 mantelpiece.

Through the opened door he saw the hall, dimly lit and thick with fog. Nothing, of course, was visible⁠—nothing but the hatstand, 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.
