I couldn’t see Stephen anymore—he was hiding just out of sight up the steps, waiting. I passed through the arch on the right and stepped onto the old platform. It was a large space, with a high vaulted ceiling. The sunken bit where the trains used to pass had been raised up to the platform level, so it was one large room. Part of the space had been converted into a two-level structure with a set of stairs. The rest was chopped up strangely. There were random walls and doorways and halls. The train tunnels were now dark passageways, leading on to more strangely shaped rooms in a place that wasn’t supposed to have any rooms. Heavy bundles of wires, a foot thick or more, ran along the walls and the edges of the floor. There were some posters left over from the days when the station was a bomb shelter, filled with slogans like CARELESS TALK COSTS LIVES and cartoons of Hitler hiding under tables. There were notices about smoking and being courteous to your sleeping neighbors.

A figure emerged from behind one of the walls. Now I understood why people thought ghosts floated. They moved with a strange ease. It looked like they had normal arms and legs that made them walk and reach, but there were no muscles in those arms and legs—no weight, no blood, none of the things that gave ordinary humans their individual ways of moving.

Aside from his silent approach, Newman was disarmingly normal.

“Hi,” I said.

“Don’t stand there in the doorway,” Newman said. “Come through.”

“I’m fine here.”

Newman was carrying what looked like an old-fashioned doctor’s bag. I’d seen these bags. They were Ripper-style prop bags, sold at stands all over the city. He set it down on an old metal worktable and opened it up.

“Well done with your message,” he said. “I’m not sure how you managed it, but it was very effective. ‘The eyes will come to you.’”

He produced a long knife with a thin blade from the bag. He was still far away from me. I’m not good at measuring distances, but it was far enough that if he ran for me, I could still turn and make a break for the stairs. But he made no indication that he intended to run at me. He poked through his bag in a leisurely fashion.

“How many of them are there?” he asked.

“What?”

“Remember some time ago, when we met?” he asked. “When I threw your friend in front of a car? I asked you if you’d ever met anyone like us, and you told me that you knew some . . . I think your words were, ‘some weirdos at home’? You were lying, weren’t you?”

I didn’t reply.
