“So he does, but there’s a wing set aside for the mentally sick,” the blond man explained.

“Oh, yes. The walls are padded. They don’t look like it, but try punching them. It’s quite fun.” He leaned out of bed and hit the wall. His fist made no sound. “It’s rubber, I think. By the way, my name’s Duncan Hopper. You may have heard of my father: Dwight Hopper.”

“I’m Malloy,” I said. “Victor Malloy.”

He cocked his head on one side and regarded me fixedly.

“Who?”

“Malloy.”
