"Demons who've been off the radar for a few hundred years?" I said. "Hmm. Amduscias, Focalor, Dantalian-" I stopped, my gut going cold.

Aratron didn't notice my reaction. "There are more than a few of them, aren't there? It's one of Baal's favorite punishments for underlords who incur his wrath-something, I'm afraid, that isn't very difficult to do."

"It's Dantalian, isn't it?"

He smiled. "Well done."

I struggled not to make the obvious connection, to think of anything but that, hurrying on with more questions. "What did Baal lock him up for? It has to do with that room, doesn't it? With walling in those men?"

Trsiel snorted. "I doubt that was his crime."

Aratron shook his head. "Your prejudices are showing, Trsiel. A cacodemon could indeed be punished for such a thing, though not for the reason you'd find the deed objectionable. Had Dantalian walled up those men against his lord's wishes, he would be punished for his insolence. That, however, was not his error." He looked at me, eyes twinkling. "I doubt it will help your cause, but do you want to hear the story?"

I nodded, brain still numb.

"Excellent. Curiosity for the sake of curiosity is the mark of a true student." He glanced at Trsiel, eyes still sparkling. "You can move closer, Trsiel. I know you want to hear this as much as she does."

Trsiel shrugged, but when Aratron looked away, he slid next to me.

"Now, one of the earls of Glamis was a half-demon. Baal's own child. As Eve knows, even the lord demons have little contact with their offspring. That doesn't keep them from watching from afar, as Balam does, but it is rare for any cacodemon to play a role in his child's life. Glamis, though, sought out that contact, and made a very persuasive argument for Baal to do otherwise, providing him with sacrifices and proving as dutiful a son as any father could want. Eventually, Baal took notice, and when Glamis had his father's attention, he asked for a boon. He would sacrifice a dozen men to Baal, not just killing them, but walling them up. As modes of death go, the only thing more terrible than being buried alive is being buried with others. The… animal instinct eventually asserts itself, providing a veritable feast of chaos."

I remembered those skeletons in the room, and the teeth marks on the bones. When I shuddered, Aratron studied my reaction with the impassive curiosity of a scientist.

"The boon," Trsiel said. "What did he ask in return?"

"Ah, well, it had to do with a lady, as these things often do. A married lady who was proving most resistant to his advances. Glamis, being an avid student of Arthurian lore, took his solution from there."

"He wanted to be able to assume the form of the lady's husband," I said. "That's where Dantalian came in. His specialty is transmigration. Not assuming another form, but possessing one."

Aratron smiled. "That's it exactly. Baal went to Dantalian and demanded that he create something to allow Glamis to inhabit another man's body. This is, of course, a skill every demon possesses." He waved a hand at his current form-probably that of a prison guard. "But for a half-demon it is impossible. Baal charged Dantalian with the task of making it possible. And he did. He created a piece of jewelry."

"An amulet," I whispered. "One that would allow anyone with demon blood to fully possess the body of any living person."

"Very good. You've heard of it, then?"

Before I could answer, Trsiel cut in. "But if Dantalian made the amulet, why did Baal imprison him?"

"Because Glamis never got that necklace. As for why, I fear that is a question only Dantalian and Baal could answer. Some say Dantalian had a follower among the Ogilvies-the clan Glamis walled up. Some say Baal denied him a share of the sacrifice. Whatever the reason, Dantalian changed his mind and secreted away the amulet, and for that, Baal sentenced him to spend five hundred and fifty-five years walled up in that room with the Ogilvies."

"That's what the Nix wants," I said, turning to Trsiel. "Dantalian's Amulet."

And I'd been the one who'd told her about it.

Once we'd taken our leave of Aratron, we returned to Amanda Sullivan's cell and I made my confession to Trsiel.

"That's why she came to Glamis," I said as I finished. "All along I've been trying to figure out what's motivating her, and it's been staring me in the face the whole time. She wants what I want. To be able to act within the living world. She's tired of relying on her partners for her food. That's why she went to Luther Ross. Same reason I've been interested in him, as a way of breaking through that barrier. But that's nothing compared to what she could do with Dantalian's Amulet. And I led her straight to it."

"We don't know that," he said softly.

I didn't argue, but we both knew it was no coincidence. I remembered the young hunter saying he'd seen something move in the woods near where we'd landed, and I remembered the creak in the hallway before Trsiel arrived. She'd been following me, and I'd rewarded her efforts beyond her wildest dreams. As soon as she'd heard of the amulet, who'd made it, and what it did, she'd headed straight for Glamis, where she'd know Dantalian had been exiled.

"If she gets the amulet, that'll make our job tougher," Trsiel said. "But I doubt that will happen. Dantalian isn't about to tell her where it is."

"No? He may not like her very much, but how long do you think it'll take before he decides that telling her-and watching the havoc she'll wreak in human form-is more rewarding than turning her down? We need to find it first."

He nodded. "But the only one who knows where it is-"

"Is the only person we can ask."

"We are not bargaining with a demon." He glanced over at me. "And don't tell me I already have. My deal with Aratron was one-sided. I did something once that, unintentionally, benefited him, and he promised me a favor in return. It wasn't a bargain."

"We aren't going to bargain with Dantalian."

"Good, because-"

"Kristof is. He's a skilled demon negotiator."

Trsiel rolled his eyes, as if this didn't come as a surprise.

"It may not be your way, but we use whatever-and whoever-proves useful."

"If you've done it before, then you can do it. No need to bring in anyone else."

"I said I've dealt with them. I've never negotiated with them. For that, I hired professionals. If you do it right, it's an honest transaction. If you do it wrong, well, then you're screwed, because there isn't a demon alive who won't take advantage of stupidity or naivety. Kris can do it right."

Trsiel leaned against the wall, arms crossed. After a few minutes, he shook his head. "Go and find him, then."

Chapter 34

I FOUND KRISTOF IN HIS OFFICE AGAIN, THIS TIME alone and hard at work, which seemed the perfect excuse to slip off and find another demon mediator. But, as always, the moment I arrived, he knew I was there, and when I tried to retreat, he called me back. His welcome cooled when he realized I was there on business.

Of course, I had to tell him everything, and this confession was ten times tougher than it had been with Trsiel. As much as it hurt to admit to Kristof that, after everything he'd said, I'd turned around and gone back in to ask about the amulet, what hurt worse was the look on his face: raw pain, but not a trace of surprise.

When I finished, I stood there, mouth still half-open, wanting to say so much, but unable to form the thoughts into words. Instead, all that came out was "I fucked up, Kris."
