“Did I just kill someone?""You can't kill a dead person," Callum said. "Makes no sense.”

“She looks like a jumper to me. Jumpers do that a lot, stand on the edge and stare out. Never kill yourself in a Tube station. Tip number one. You might end up down here forever, staring at the wall."Stephen coughed a little."Just giving advice," Callum said.”

“Boo: "Go talk to her."Callum: "About what?"Boo: "Anything."Callum: "You want me to walk up to her and say, 'Are you a ghost?'"Boo: "I do that."Callum: "I love it when you get it wrong.”

“I dumped out the bag and found what had been inside was a bunched-up police uniform, complete with the vest."Where did you get this?" Boo asked."It's Callum's," he said."What's he wearing?""At the moment, not much of anything. Put it on."I noticed Book perk up a bit at this piece of information.”

“I envisioned huge piles of the Elf Hotel flying off the belt, taking down everybody in sight. I had seen pictures of that Elf Hotel - it had sharp candy-cane spires that could easily impale someone. If anyone was ever going to be killed by an Elf Hotel, it would be my parents.”

“It's us," Stephen said."Oh, thank God," said a voice.Callum emerged from behind the Dumpster. Even with all that was going on, it was hard not to take notice of this: he wore only his underpants and his socks and shoes....I don't think I hid my staring very well either."Go ahead and change," Stephen said, handing me the bag. "I'll go and get the car.""Please be quick," Callum added. "This is not as fun as it appears.”

“I followed your footsteps," he said, in answer to the unspoken question. "Snow makes it easy." I had been tracked, like a bear. "Sorry to make you go to all that trouble," I said. "I didn't have to go that far, really. You're about three streets over. You just kept going in loops." A really inept bear.”
