More people vomited, and there was general backing away from Dead Boy. I looked apologetically at Jeremiah.

“Sorry about that. Being dead hasn’t mellowed him at all. He doesn’t get invited out much, you know.”

“Really?” said Jeremiah. “You do surprise me.”

“Nice use of the Voice,” I said to Walker. “But I have to wonder, with the Authorities dead and gone now, who’s powering it? Or should that be What, rather than Who?”

“Life goes on,” Walker said easily. “And I’m still in charge. Because somebody has to be. Certainly I don’t see anyone suitable coming forward to replace me.”

“You’ve always hated the Nightside,” I said. “You told me it was your dearest wish to wipe out the whole damned freak show, before it spilled out over its boundaries to infect the rest of the world.”

“Perhaps I’m mellowing in my old age,” said Walker. “All that matters is that I am still here, preserving order in the Nightside, and with the Authorities gone, I have a much freer hand to go after those who threaten the way things are.”

“I see,” I said. “And would that include people like me?”

“Probably,” said Walker.

“You kidnapped my grand-daughter!” Jeremiah said abruptly, his face ablaze with the power of a new idea, glaring right into Walker’s face. “You walked right past my security and used your Voice to make Melissa leave with you! What is she? Your hostage, your insurance to stop me from taking my rightful place as ruler of the Nightside?”

“That certainly sounds like something I might do,” murmured Walker. “But I don’t need to stop you from taking over. You’re not up to it. And I wouldn’t take your grand-daughter because we both know I’d be the first person you would come after. And I don’t want another war in the Nightside, just yet.”

“You think I’d take your word for it?” snorted the Griffin. “I’ll tear this whole city down to find where you’ve hidden her!”

“Would you swear to me that you had nothing to do with Melissa’s disappearance?” I said quickly to Walker.

“Would you swear it, on my father’s name?”

“Yes, John,” said Walker. “I’ll swear to that, on your father’s name.”

I looked at Jeremiah. “He hasn’t got her.”

“How can you be so sure?” Jeremiah said suspiciously. “Exactly how closely are you two connected?”

“Long story,” I said. “Let’s just say…he knows better than to lie to me.”

Walker nodded politely to Jeremiah, tipped his bowler hat briefly to me, and walked unhurriedly out of the ballroom. No-one said anything, or tried to stop him, not even Jeremiah. Shortly after Walker left, the butler Hobbes arrived with a small army of servants to clean up the mess and restore order to the demolished hedges and rose-bushes trampled by the golems. The party slowly resumed, with much animated chatter over what had just happened. They’d be telling stories about it for years.

Surprisingly, the Griffin didn’t seem at all put out. Once Walker was gone, Jeremiah calmed right down and even started smiling again. “Nothing like a little excitement to get your party talked about,” he said cheerfully. “Look at Mariah, surrounded by all her friends and hangers-on, all of them comforting her and offering to bring her food or drink or anything else she might desire…and she’s loving it. She’s the centre of attention now, and that’s all she ever wanted. Behind the tears and the swoons, she knows all this excitement guarantees her party will be written up in all the right places, and anyone who wasn’t here will be killingly jealous of everyone who was.”

He looked at me thoughtfully. “One of the problems with living as long as we have is that you’ve seen it all, done it all. Boredom is the enemy, and anything new is welcomed, good or bad. Everyone in my family is preoccupied with finding new things to distract and entertain them. I’ve spent centuries fighting and intriguing to gain control of the Nightside, because…it was there. The most difficult task I could set myself, and the biggest prize. Anything less…would have been unworthy of me. And now it infuriates me! That I’m so close to winning it all, and perhaps a bit too late!”

“Because you’re expecting to die soon?” I said bluntly.

“There’s a way out of every bargain,” said Jeremiah, not looking at me. “And a way to break every deal. You only have to be smart enough to find it.”

“Even if it means killing your own grand-children to stay alive?”

He finally looked at me, and surprised me by laughing, painfully. “No. I couldn’t do that. Not even if I wanted to.”

“You have to tell me the truth,” I said. “The whole truth, or I’m never going to get anywhere with this case. Talk to me, Jeremiah. Tell me what I need to know. Tell me about the cellar under this house, for instance, and why no-one but yourself is ever allowed to go down there.”

“You have been digging, haven’t you?” said Jeremiah.

“You do want me to find Melissa, don’t you?”

“Yes. I do. Above everything else, I want that.”

“Then either take me down to the cellar and show me what you’ve got hidden there, or tell me the truth about how you became immortal.”

The Griffin sighed but didn’t seem too displeased by my insistence. “Very well,” he said finally. “Come with me, and we’ll discuss this in private.”

I was half-expecting another privacy field, but the Griffin led me over to a corner of the ballroom, produced a small golden key on a length of gold chain, and fitted the key carefully into a small lock hidden inside a particularly rococo piece of scroll-work. The key turned, and a whole section of the wall swung open, revealing a room beyond. Jeremiah ushered me in, then shut and locked the door behind us. The room was empty, the walls bare, dimly lit by a single light that came on as we entered.

“I keep this room for private business conferences,” said Jeremiah. “It’s specially shielded against all eavesdroppers. You’d be surprised how much business gets done at parties. Hobbes will stand guard outside, to see that we’re not disturbed. So…here I am at last, finally about to tell someone the true story of my beginnings as an immortal. I always thought I’d find it difficult, but now that the moment has arrived I find myself almost eager to unburden myself. Secrets weigh you down; and I have carried this one for so many years…

“Yes, John. I really did make a deal with the Devil, back when I was nothing more than a simple mendicant in twelfth-century London. It wasn’t even particularly difficult. Heaven and Hell were a lot closer to people in those days. I took an old parchment scroll I’d acquired in part payment of an old debt and used it to summon up the Prince of Darkness himself.” He stopped abruptly, looking at his hands as they shook, remembering the moment. “I abjured and bound him to appear in a form bearable to human eyes, but even so, what I saw…But I was so very ambitious in my young days, and I thought I was so clever. I should have read the contract I signed in my own blood more carefully. The Devil is always in the details…

“There is a clause, you see, in that original infernal document, which states that any grand-child of my line, once safely born, cannot be killed by me. Neither can I have them killed, or through inaction allow them to come to harm. On pain of forfeiture of soul. So once I discovered their existence and had them brought before me, all that was left…was to embrace them. In a way I never did, or could, with William and Eleanor. Two grand-children were my death sentence, the sign of my inevitable damnation, but I couldn’t say their existence came as much of a surprise. I did everything I could to ensure I’d never father children, but they came anyway. I could have had them killed, but…a man wants his line to continue, even if he knows it means his end. I’m a ruthless man, John. I’ve destroyed many men in my time. But I never once harmed a child.
