On Wednesday, the seventh of November, I woke around five in the morning. My brain had suddenly clicked back on, and my heart was racing. I sat up and looked around the dark room, examining every formation. That was my nightstand next to my bed. There was my bureau. There was the wardrobe door, slightly open, but not enough for someone to hide behind. There was Jazza, asleep in her bed. I grabbed my hockey stick and stabbed around under my bed, but felt nothing. Then I realized that that wasn’t a very good test for a ghost, so I stood up on the bed and jumped out as quietly as I could, then got down on the floor and looked underneath. No one was there. Jazza shifted, but she didn’t wake.

I took my robe and bath basket and walked quietly down to the bathroom, where I examined every stall and every cubicle before taking my shower, and even then, I kept the curtain partway open. I didn’t care if anyone walked in.

I went to breakfast as soon as it opened, long before Jazza was out of bed. I saw Callum standing on the corner, over by the refectory. He was wearing a dark blue London Underground suit with an orange Day-Glo vest over the jacket, and he had a clipboard. If he had planned on trying to blend in, that wasn’t really working.

“What are you doing?” I said.

“Pretending to survey traffic patterns for a new bus route. I have a clipboard and everything.”

“Did you guys make that up?”

“Course we made it up,” he said. “It was the only thing we could think of to justify my standing in front of a school all day, and the clipboard was the only prop we had. And you shouldn’t be seen talking to me, so keep moving.”

He turned back to his clipboard, ending the conversation. I hurried away from him, feeling stupid.

I was the only person at breakfast at that hour. I tried to eat my normal plate of sausages but could only get down some juice and the bitter, lava-hot coffee. For entertainment, I read the brass plaques on the wall—names of former students and their various achievements. I looked at the stained-glass image of the lamb in the window above me, but that only reminded me that lambs are famous for being led to slaughter, or sometimes hanging out with lions in ill-advised relationships.

I had to know what they could do to stop the Ripper. I had to find out, or I would go insane. I got up, shoved my tray into the rack, and went back outside and right up to Callum.

“I just said—”

“I want to see what you do,” I said.

“You’re looking at it.”

“No, I mean . . . I want to see how you take care of them.”

He kicked at the cobbles.

“I can’t do that,” he said.
