“Of course, if you want me to.” Making it clear that she was puzzled but determined, she stepped through the doorway and pressed down the switch with a fingertip. “What am I meant to be seeing, Jonathan? It’s just a room.”

“Have a better look,” he said, though he was tempted to believe her: the room was emptier than last time he’d seen it — the bed had been stripped to its stale piebald mattress. His grandmother wouldn’t want to lie on that; perhaps she was hiding in one of the massive wardrobes, though she’d disliked games she considered to be childish. He urged himself into the room and swung around to catch Trudy’s hand again. “Let’s look in-”

His voice froze in his throat as he saw what was crouched behind her in the dimmest corner of the room. It could almost have been a swollen bunch of sticks, except that it was patched with rags of clothes or skin. Lolling on top of it was an object that looked pinched with chill and peeling with damp and distorted by worse than either.

He felt her grow tense and make herself relax. She was beginning to turn her head when the shape in the corner unfolded itself and tottered to its full height. It jerked out a hand with little in the way of fingers, and he thought it was going to fasten on Trudy’s shoulder. The next moment the light was gone, and Trudy clutched at him. “Did you-”
