“You are the only lead,” Stephen said. “Every other avenue has been tried. The paper and the package that was sent to the BBC . . . analyzed over and over. Paper and box and wrapping from Ryman’s stationers—one of thousands they sell every year. Not particularly helpful, as he obviously didn’t buy it—an invisible man can’t walk into a shop and buy a box—so we couldn’t trace it at the point of sale. CCTV turned up nothing, as is now well-known. No physical evidence at any crime scene to tie back to the killer—again, obvious to us, baffling to the lab. We only had you. From you, we at least knew he wasn’t the original Jack the Ripper, because of his appearance . . .”

I think he saw that none of this was helping, so he shut up.

“The plan is simple,” he said. “You stay at Wexford, and we stay near you. Very near you. If he comes anywhere near you—”

“He came near me tonight,” I said.

“So we double our protection,” Stephen said. “It won’t happen again. But now you know, and you have to listen to us, and you have to trust us.”

“What can you do?” I said, my voice shaking. “If he comes near me, what can you do about it?”

Callum opened his mouth to speak, but Stephen shook his head.

“We take care of it,” Stephen said. “The details are covered under the Official Secrets Act. You can be angry. You can be upset. You can be whatever you want. But the truth is, we’re the only people who can keep you safe. And we will keep you safe. It’s not only our job, but now he’s hurt our friend, and that happens to bother us quite a lot.”

“I could go home,” I said.

“Running away won’t help. Going home probably wouldn’t even deter him, if he’s serious. The ghosts we’ve encountered operate basically in the same manner as humans in terms of general locomotion. While most tend to haunt one place, there are plenty that have much larger territories. The Ripper seems comfortable moving around the East End. There’s no reason I can think of that he wouldn’t be able to travel.”

He didn’t sugarcoat it. The bluntness was oddly calming.

“So you stay where we can do something about it,” he went on. “And you try to live your life as normally as you can.”

“Like you two?” I asked.

It was a bit of a low blow, but Callum laughed.

“I think she’s getting it,” he said.

IT WAS ALMOST THREE IN THE MORNING WHEN STEPHEN dropped me off at Wexford, but there were lots of lights on in the windows. I saw people looking out as I stepped from the police car.
