Sanguine gave a little sigh. “Let me make it easy on you. It’s something to do with a prisoner, isn’t it?”

Jethro nodded. “An escaped prisoner.”

“Why, that just happens to be one of my favourite kind. The escaped prisoner in question wouldn’t happen to be Springheeled Jack, now would it?”

“You... you know?”

“Of course we know. Why d’you think we’re in town? Now, a guy like you, Jethro, an up-and-comer, if you will, he’d be inclined to keep abreast of developments in the search for said escaped prisoner, now wouldn’t he?”

“He would. I mean, I would. Yes. Please don’t kill me.”

“Let’s not get ahead of ourselves. Jack’s on the run, and you folk are closing in on him. I wanna know where the search is being concentrated. And don’t bother lying. As you can see, some facts I already know, so you better be sticking to them ’less you want me in a bad mood.”

Jethro swallowed, and did his best to stand a little straighter. “Let me go. You let me go and then I’ll tell you. You can’t... you can’t threaten me. I have the information you want and… and you’re not going to kill me before I tell you. You’re just trying to scare me.”

“People scare better when they’re dying.”

Jethro stopped trying to stand straight. “The East End,” he croaked. “Spitalfields. We have it closed off. Nothing can get by the cordon without us knowing about it. He’s trapped. He’s got no way out.”

Sanguine grinned. “Jethro, you have been a most helpful captive.”

“Are you... are you going to let me live?”

Sanguine’s grin grew wider. “Not even remotely.”

With Jethro, the second Jethro, lying dead in the alley amid the junk and the debris of London, the ground cracked and crumbled beneath Sanguine’s feet and he sank into the cold embrace of the earth. He moved down to absolute pitch-black, to a darkness no human eye could penetrate, and he watched the dirt and rock shift before him, the individual grains undulating in streams, like a school of fish, flowing round him and allowing him through.

He stopped for a moment, listening to the vibrations that spoke to him louder than any voice, then burrowed sideways. He slowed as the ground parted, opened for him like a door, and harsh light spilled in against his sunglasses. Sanguine had no eyes to hurt, and he stepped on to the train platform, feeling the wall close up behind him. The platform was almost empty, five people waiting there, not one of them having noticed his arrival.
