"All right," I said steadily. "What's changed? Why are you ready to reveal yourselves, over the Apocalypse Door?"

"I told you, it's complicated," Rafe said sullenly. "The Elders now believe that immortality isn't necessarily all it's cracked up to be. Are they, in fact, missing out on something? As in, the greater experiences and possibilities of an afterlife? Don't look at me like that. Don't be so limited in your thinking. They've lived for centuries. They've exhausted all the pleasures of this world, and now they lust after new adventures in the next world. Heaven. Paradise.

Why settle for anything less? But, they're afraid of Hell. After all the things they've done. They believe the Apocalypse Door can be… turned. Reversed. Made over, into a Paradise Door. So they can open it and go straight through into Heaven. After Doctor Delirium and Tiger Tim have served their purposes, we'll take the Door away from them, turn it around, and then all the Elders will go through into Paradise, and explore all the pleasures that may be found there."

He smiled at the Armourer, in a silly sort of way. "I don't know why I'm telling you all this. You slipped me a dose of your truth drug, didn't you?"

"Right into the main feed tube," said the Armourer. "You were so busy boasting you never even noticed."

"Bastard."

"Keep talking," I said. "What happens to the Immortals, after the Elders pass on?"

"Well, to start with, everyone else moves up one place. Promotions all round! The eldest remaining offspring will take control, and the Immortals go on. Forever and ever and ever. We may not be technically immortal, like the Leader and the Elders, but we still live many lifetimes. Some of us are quite keen for the Elders to go through the Door, so we can take over and run things the way we think they ought to be run. It's our time now, and we'll make the world jump…"

"Don't you want to go to Paradise?" I said.

Rafe sniffed loudly. "The Elders might believe in the Door; the rest of us have more sense. They're old and tired, they've lost their appetite for life. We want to make the world dance to our tune, and eat it all up with spoons. Oh, the plans we have… You're really not going to like them."

He giggled happily.

The Armourer and I moved away from the Immortal in his chair, so we could talk quietly together. As a Drood, you learn to believe ten impossible things before breakfast, and have a plan ready to deal with them by lunchtime. But this… was a bit much.

"Is this even possible?" I said to the Armourer.

"Storming Heaven, and forcing your way in?" said the Armourer.

"I doubt it. Theologically flawed, at best. But who knows what living for thousands of years has done to these people's minds? The point is, if they believe it, they could open the Apocalypse Door and let loose all the hordes of Hell, while thinking they were doing something else entirely."

"I can still hear you, you know," said Rafe. "The Elders dictate policy, and leave us poor bastards to carry it out. The Door is a supremely powerful artefact, and that's all that really matters. We will master it, as we have mastered everything else that has come into our possession. We will uncover its true nature and capabilities, and use it to make us even more powerful. Because that's what we do. If the Elders disappear through it-fine. After they've gone, we'll use the Door to blackmail everyone. The governments of the world will do anything, give us anything, as long as we promise not to open the Door."

"I thought you already ran the world," I said.

"Indirectly," said Rafe. "The Elders always believed in keeping to the shadows, lest the world discover just how few of them there were. They ruled by pulling strings; a lot of us youngsters yearn to be more hands on. And get our hands dirty."

He giggled again, while I looked at the Armourer.

"How much more do you think we can get out of him?"

"Don't look at me," said the Armourer. "I haven't used this truth stuff since nineteen sixty-two. I'm surprised it still works. I was just bluffing, to put him in the right frame of mind. It'll take me a couple of days to whip up another batch. And I've no idea what repeated use might do to him. He could tell us everything he knows, from his childhood on, or his brains could start leaking out his ears. Not that I care, after everything he's done. Arrogant little shit. But, I'd ask your questions now, if I were you. While he's still feeling talkative."

I turned back to Rafe. "What other traitors are there, inside the Droods?"

"Wouldn't you like to know?" said Rafe, grinning widely. "Lots and lots… Probably. Not just Immortals, either. We're not the only ones who understood the advantages of having a man on the inside…"

"That could be merely an opinion," murmured the Armourer.

"Just because he believes it's true, doesn't mean it is. I can't believed we're riddled with traitors and informers. I'm sure we'd have noticed…"

"How many Immortals are there, posing as Droods!" I said to Rafe. "I want names!"

"I don't know! None of us know! We're all only ever told what we need to know, just like your field agents." He studied the Armourer, with something of his old cold arrogance back in his face. "Basic security measure. You can't be made to tell what you really don't know."

"Did you kill my mother?" said the Armourer. "Are you responsible, for the murder of the Matriarch?"

"Were you responsible for the death of my Molly?" I said. "Or Sebastian, back during the Hungry Gods War?"

He tried to shrug, inside the restraint of the straps. "Not me personally, but yes… that was all down to us. Don't ask me why. I don't know. Not my mission. I was just told to take advantage of the chaos, grab as much as possible, and then get the hell out of Dodge before my cover was blown."

"Molly," I said. "Tell me about what happened, to Molly."

"Ah yes," said Rafe, smiling unpleasantly. "They did tell me about that. We wanted to see what Doctor Delirium's addition to the Acceleration Drug would do to the Droods, on its own. So one of us dropped a little into the air-conditioning system. It's amaz ing what people will do, what they're capable of, if you give them just a little push in the right direction. Even goody little two-shoes Droods can be made to run wild, if you push the right chemical buttons in their brains. Shame it didn't last longer… but then, you can't have everything."

"You killed my Molly," I said, leaning in close. "You Immortals. I will kill you all, for that. I will cut you down and trample you underfoot, and make you extinct."

Rafe looked at me, but though he met my gaze steadily enough, he had nothing to say. The Armourer took me by the elbow, and pulled me gently away so he could talk to the Immortal.

"How were you able to masquerade as Droods?" he said bluntly. "How could you pretend to have torcs, and armour?"

"Because we did, for a long time," said Rafe. "The Heart remembered the Immortals, and indulged us. I think we amused it. We've been inside the Droods, working both for and against you, for centuries now. Of course, that all changed after the Heart was destroyed. A definite setback there, thanks to you, Eddie. Who knew one man could make so much trouble for everyone?"

"It's a gift," I said. "But flattery will get you nowhere. What did you do, after Ethel gave the family new torcs and new armour?"

"We learned to fake it," Rafe said easily. "We've had centuries to learn how to hide in plain sight. Our scientists produced new torcs, good enough to hide us from Ethel, unless she looked really closely, and why should she? We made it easier on ourselves by only substituting Droods who would probably never be called on to armour up."

"But we're a family," I said. "We're all so close, living on top of each other in the Hall. How could you fool everybody? How could we not notice?"
