created a kind of outlet for the demon’s personality—embodied as an entirely discrete mental entity living right in my own head, presumably in the ninety percent of the brain that humans never use. Or in my case, maybe ninety-five. Lasciel could appear to me, could see what I saw and sense what I sensed, could look through my memories to some degree and, most disturbing, could create illusions that I had to work hard to see through—just as she was now creating the illusion of her physical presence in my car. Her extremely attractive and wholesome-looking and entirely desirable presence. The bitch.
“I thought we had an understanding,” I growled. “I don’t want you coming to see me unless I call you.”
“And I have respected our agreement,” she said. “I simply came to remind you that my services and resources are at your disposal, should you need them, and that the whole of my self, currently residing beneath the floor of your laboratory, is likewise prepared to assist you.”
“You act like I wanted you there in the first place. If I knew how to erase you from my head without getting killed, I’d do it in a heartbeat,” I replied.
“The portion of me that shares your mind is nothing but the shadow of my true self,” Lasciel said. “But have a care, mortal. I am. I exist. And I desire to continue to do so.”
“Like I said. If I could do it without getting killed,” I growled. “In the meanwhile, unless you want me to chain you into a little black closet in my head, get out of my sight.”
Her mouth twitched, maybe in irritation, but nothing more than that showed on her face. “As you wish,” she said, inclining her head. “But if black magic truly is once more rising within Chicago, you may well have need of every tool at hand. And as you must survive for me to survive, I have every reason to aid you.”
“A tiny black box,” I said. “Without holes in the lid. Smelling like my high school locker room.”
Her mouth curled again, an expression of wary amusement. “As you wish, my host.”
And she was gone, vanishing back into the undeveloped vaults of my mind or wherever she went. I shivered, making sure my thoughts were contained, shielded from her perceptions. There was nothing I could do to prevent Lasciel from seeing and hearing everything I did, or from rummaging randomly in my memories, but I had learned that I could at least veil my active thoughts from her. I did so constantly, in order to prevent her from learning too much, too quickly.
That would only help her reach her goal—that of convincing me to unearth the ancient silver coin buried under my lab and sealed within spells and concrete. Within the coin, the old Roman denarius—one of a collection of thirty—dwelt the whole of the fallen angel, Lasciel.
If I chose to ally myself with her, it would get me all kinds of strength. The power and knowledge of a fallen angel could turn anyone into a deadly and virtually immortal threat—at the low, low cost of one’s soul. Once you signed on with one of the literal Hell’s Angels, you weren’t the only one in the captain’s chair anymore. The more you let them help you, the more you surrendered your will to them, and sooner or later it’s the fallen angel that’s calling the shots.
I’d grabbed the coin a heartbeat before a friend’s toddler could reach down for it, and touching its surface had transferred a portion of the personality, the intellect of Lasciel into my head. She helped me survive several nasty days the previous autumn, and her assistance had been invaluable. Which was the problem. I couldn’t allow myself to continue relying on her help, because sooner or later, I’d get used to it. And then I’d enjoy it. And at some point, digging up that coin in my basement wouldn’t seem like such a bad idea.
All of which meant that I had to stay on my guard against the fallen angel’s suggestions. The price may have been hidden, but it was still there. Lasciel wasn’t wrong, though, about how dangerous situations involving true black magic could become. I might well find myself in need of help.
I thought about those who had fought beside me before. I thought about my friend Michael, whose kid had been the one about to pick up the coin.
