The snakeman stared at me for a very long time. Then he started to rasp and shake. It took me a minute to realize that he was laughing at me. Snakes weren't really meant for laughter. It didn't sit well on a serpentine body.

"You cannot threaten me," he said. "There is nothing you can do to me."

"I see a couple of holy swords here that make me think otherwise."

"No," the Denarian said. He reached up to his forehead and clawed at the sigil there, as if trying to peel off his own skin. The symbol flashed, and then faded, along with the second set of eyes. The whole of him rippled, scales abruptly melting away. For a second, the features of Father Vincent emerged from beneath the scales. Then they too faded away, replaced by a man's pinched and hardened features. He was dark of skin, maybe Moorish, and he wasn't big. Five feet and a little change, and not more than one-fifty. Average height, several centuries ago.

The man lowered his hand and let a slightly tarnished silver coin roll across the floor to Michael's feet. "My name is Quintus Cassius, and I have long been slave to the will of the demon Saluriel." His dark eyes glittered with malice, and his tone dripped with sarcasm. "I beg you for mercy and the chance to mend my ways. How ever can I thank you, Sir Knight, for saving me from that torment."

Shit. He was playing the morality card. I shot a glance at Michael.

The big man frowned at snakeboy Cassius, but didn't miss a beat in drawing out a white handkerchief embroidered with a silver cross, and folding the coin up in it. Michael and Sanya exchanged a long look, and then both of them put away their swords.

"Uh, guys. What the hell are you doing? Dangerous demon murderer here, remember?"

"Harry," Michael said. "We can't. Not if he's surrendered the coin and asked mercy."

"What?" I demanded. "That's stupid."

"Of course it is," Cassius said. Glee danced in his voice. "They know that I am not sincere. They know I will turn on them at the first opportunity. That I will obtain one of the other coins and return to what I have done for centuries."

I stood up, angry enough that the chair fell over. "Michael, if you turn the other cheek on this bastard he'll tear it off your face. You're supposed to be the freaking Fist of God."

"No, I'm not, Harry," Michael said. "The purpose of the Knights is not to destroy those who serve evil."

"Indeed not," Cassius said. Somehow, there was more of a hiss in his voice now than when he'd been a snake. "They're here to save us."

"To save them?" I stared at Michael. "Is he kidding?"
