With shaking fingers but a determined heart he lit the gas, and the first thing in which his eyes corroborated the evidence of his ears was the horrifying detail that the lower portion of the partition bulged unnaturally into his own room. The glaring paper with which it was covered had cracked under the tension and the boards beneath it bent inwards towards him. What hideous load was behind them, he shuddered to think. All this he saw in less than a second. Since the final lurch against the wall not a sound had proceeded from the room, not even a groan or a foot-step. All was still but the howl of the wind, which to his ears had in it a note of triumphant horror. Shorthouse was in the act of leaving the room to rouse the house and send for the police--in fact his hand was already on the door-knob--when something in the room arrested his attention. Out of the corner of his eyes he thought he caught sight of something moving. He was sure of it, and turning his eyes in the direction, he found he was not mistaken. Something was creeping slowly towards him along the floor. It was something dark and serpentine in shape, and it came from the place where the partition bulged. He stooped down to examine it with feelings of intense horror and repugnance, and he discovered that it was moving toward him from the _other side_ of the wall. His eyes were fascinated, and for the moment he was unable to move. Silently, slowly, from side to side like a thick worm, it crawled forward into the room beneath his frightened eyes, until at length he could stand it no longer and stretched out his arm to touch it. But at the instant of contact he withdrew his hand with a suppressed scream. It was sluggish--and it was warm! and he saw that his fingers were stained with living crimson. A second more, and Shorthouse was out in the passage with his hand on the door of the next room. It was locked. He plunged forward with all his weight against it, and, the lock giving way, he fell headlong into a room that was pitch dark and very cold. In a moment he was on his feet again and trying to penetrate the blackness. Not a sound, not a movement. Not even the sense of a presence. It was empty, miserably empty! Across the room he could trace the outline of a window with rain streaming down the outside, and the blurred lights of the city beyond. But the room was empty, appallingly empty; and so still. He stood there, cold as ice, staring, shivering listening. Suddenly there was a step behind him and a light flashed into the room, and when he turned quickly with his arm up as if to ward off a terrific blow he found himself face to face with the landlady. Instantly the reaction began to set in.
