"Do it again," I said. This time I didn't look at the cross: I watched the vampire. I wasn't able to track his movements — he was too fast — but I caught brief glimpses of him as he darted forward, snatched up the cross, and leaped back.

"So you're not able to move things with your mind?" I asked.

"Of course not." He laughed.

"Then why the click of the fingers?"

"To distract the eye," he explained.

"Then it's a trick," I said. "It's got nothing to do with being a vampire."

He shrugged. "I could not move so fast if I were human, but yes, it is a trick. I dabbled with illusions before I became a vampire, and I still like to practice."

"Could I learn to do it?" I asked.

"Maybe," he said. "You cannot move as fast as I can, but you could get away with it if the object was close to hand. You would have to practice hard — but if you wish, I can teach you."

"I always wanted to be a magician," I said. "But… hold on…" I remembered a couple of occasions when Mr. Crepsley had opened locks with a click of his fingers. "What about locks?" I asked.

"Those are different. You understand what static energy is?" My face was a blank. "Have you ever brushed a comb through your hair and held it up to a thin sheet of paper?"

"Yeah!" I said. "The paper sticks to it."

"That is static energy," he explained. "When a vampire flits, a very strong static charge builds up. I have learned to harness that charge. Thus I am able to force open any lock you care to mention."

I thought about that. "And the click of your fingers?" I asked.

"Old habits die hard." He smiled.

"But old vampires die easy!" a voice growled behind us, and before I knew what was happening, someone had reached around the two of us and pressed a pair of razor-sharp knives to the soft flesh of our throats!
