He smashed a stone against the glass of the window, and the crash was like an explosion. A splinter of glass cut the back of his hand, but he hardly noticed it. He bent his elbow and broke off the jagged splinters which stuck out from the side, then groped for the window-catch. It sprang back sharply, and he pushed the window up.

It was pitch dark inside the room.

He used his torch for the first time. The beam shone upon oddments of furniture, the mirror of a huge sideboard, and a door. He climbed through, but heard no more screaming. Whoever had carried that lamp must have heard the window crash, but there was only silence. He reached the door, pulled it open and stepped into the passage. A faint glow of light came from upstairs, enough to show him the narrow stairs themselves, the gloomy hall, the glass in the picture-frames hanging on the walls. He put out his torch and stood quite still.

There was no sound, no movement.

Had he heard that scream ?

His teeth were set so hard that his cheeks hurt. He went slowly towards the foot of the stairs. Now that he was more accustomed to the light he could pick out the banisters, the shiny handrail, the dark, blotchy wallpaper.

He must go upstairs; he wasn’t a victim of nerves.

He started up the stairs, keeping close to the wall to avoid creaking boards. The light still glowed, dimly yellow. He reached a small landing and stood quite still, from the first attack of nerves, warning himself to be careful. There were three doors, one of them wide open, and the light came from this room. He stepped softly towards it, and peered inside. It was an empty bedroom; empty, that was, as far as he could see. A huge double bed, with big brass knobs on the posts, stood against one wall. Backing on to the window was a huge Victorian dressing-table with a big centre and narrow wing mirrors. The oil-lamp, without a shade, stood on this, and the light was brighter here because it was reflected from the mirrors.
