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 re-light the lamp when an audible movement in the room behind made him pause. Smoke leaped down from his knee and moved 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 window-panes, 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 hall-way, 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 necesssary to the invasion of the room that was about to take place, since neither doors nor windows, nor any other solid barriers could interpose an obstacle to what was seeking entrance. Yet the opening of the door would be significant and symbolic, and he distinctly shrank from it.
