My stomach twisted. One of these days, I’m going to have to learn to keep my mouth shut. Nicodemus had just casually had a young man maimed solely to make a point to me for teasing him about it. I clenched my jaw and resolved to use the incident to remind me exactly the kind of monster I was dealing with here.

“There,” Nicodemus said, turning back to Mab. “I apologize for any inconvenience.”

“Shall we conclude our business?” Mab said. “My time is valuable.”

“Of course,” Nicodemus said. “You know why I have approached you.”

“Indeed,” Mab said. “Anduriel once loaned me the services of his . . . associate. I now repay that debt by loaning you the services of mine.”

“Wait. What?” I said.

“Excellent,” Nicodemus said. He produced a business card and held it out. “Our little group will meet here at sundown.”

Mab reached for the card and nodded. “Done.”

I intercepted her hand, taking the card before she could. “Not done,” I said. “I’m not working with this psychopath.”

“Sociopath, actually,” Nicodemus said. “Though for practical purposes, the terms are nearly interchangeable.”

“You’re an ugly piece of work, and I don’t trust you any farther than I can kick you, which I’m tempted to see how far I can do,” I snapped back. I turned to Mab. “Tell me you aren’t serious.”

“I,” she said in a hard voice, “am perfectly serious. You will go with Archleone. You will render him all aid and assistance until such time as he has completed his objective.”

“What objective?” I demanded.

Mab looked at him.

Nicodemus smiled at me. “Nothing terribly complex. Difficult, to be sure, but not complicated. We’re going to rob a vault.”

“You don’t need anyone to help you with that,” I said. “You could handle any vault in the world.”

“True,” Nicodemus said. “But this vault is not of this world. It is in fact, of the Underworld.”

“Underworld?” I asked.

I was getting a bad feeling about this.

Nicodemus gave me a bland smile.

“Who?” I asked him. “Whose vault are you knocking over?”

“An ancient being of tremendous power,” he replied in his roughened voice, his smile widening. “You may know him as Hades, the Lord of the Underworld.”

“Hades,” I said. “The Hades. The Greek god.”

“The very same.”

I looked slowly from Nicodemus to Mab.

Her face was beautiful and absolute. The chill of the little earring that was keeping me alive pulsed steadily against my skin.

“Oh,” I said quietly.“Oh, Hell’s bells.”

My brain shifted into overdrive.

My back might have been against a wall, but that was hardly anything new. One thing I’d learned in long years of spine-to-brick circumstance was that anything you could do to create a little space, time, or support was worth doing.

I met Mab’s implacable gaze and said, “It is necessary to set one condition.”

Her eyes narrowed. “What condition?”

“Backup,” I said. “I want an extra pair of eyes along. Someone of my choosing.”

“Why?”

“Because Nicodemus is a murderous murdering murderer,” I said. “And if he’s picking a crew, they’re going to be just as bad. I want another set of eyes along to make sure one of them doesn’t shoot me in the back the second I’m not looking—you’re loaning out the Winter Knight, after all. You’re not throwing him away.”

Mab arched an eyebrow. “Mmmm.”

“Out of the question, I fear,” Nicodemus said. “Plans have already been made and there is no room for extraneous personnel.”

Mab turned her head very slowly to Nicodemus. “As I remember it,” she said, her tone arctic, “when you loaned me your service, you brought your spawn with you. I believe this request exhibits symmetry.”

Nicodemus narrowed his eyes. Then he inhaled deeply and inclined his head very slightly in agreement. “I do not have explicit authority over everyone involved. I can make no promises as to the safety of either your Knight or his . . . additional associate.”

Mab almost smiled. “And I can make none as to yours, Sir Archleone, should you betray an arrangement made in good faith. Shall we agree to an explicit truce until such time as your mission is complete?”

Nicodemus considered that for a moment before nodding his head. “Agreed.”

“Done, then,” Mab said, and plucked the card from my fingers. “Shall we go, my Knight?”

I stared hard at Nicodemus and his bloody-mouthed daughter for a moment. Deirdre’s hair rasped and rustled, slithering against itself like long, curling strips of sheet metal.

Like hell was I gonna help that lunatic.

But this was not the time or place to make that stand.

“Yeah,” I said through clenched teeth. “Okay.”

And without ever quite turning my back on the Denarians, I followed Mab back to the elevator.

* * *

At the bottom of the elevator ride, I turned to Mab’s bodyguards and said, “Time for you guys to get out and bring the car around.” When none of them moved, I said, “Okay. You guys filled out some kind of paperwork for how you want your remains disposed of, right?”
