Then I closed my eyes, and drew upon the energy gathered in the circle. I brought it into me, molded it, shaped it into the effect I was looking for with my thoughts, fiercely picturing the talisman I'd given Lydia while I did. The energy built and built, a buzzing in my ears, a prickling along the back of my neck. When I was ready, I spread my hands over the two objects, opened my eyes and said, firmly, " Duo et unum." At the words, the energy poured out of me in a rush that left me a little light-headed. There were no sparks, no glowing luminescence or anything else that would cost a special effects budget some money-just a sense of completion, and a tiny, almost inaudible hum.

I picked up the bracelet and put it back on, then took up the tuning fork and smudged the circle with my foot, willing it broken. I felt the little pop of the residual energies being released, and I rose up and fetched my exorcism bag from the Beetle. Then I walked away, down the sidewalk, holding my tuning fork out in front of me. After I'd taken several paces away, I turned in a slow circle.

The fork remained silent until I'd turned almost all the way around-then it abruptly shivered in my hand, and emitted a crystalline tone when I had it facing vaguely northwest. I looked up and sighted along the tines of the fork, then walked a dozen paces farther and triangulated as best I could. The direction change on the way the fork faced when it toned the second time was appreciable, even without any kind of instruments-Lydia must have been fairly close.

"Yes," I said, and started off at a brisk walk, sweeping the tuning fork back and forth, setting my feet in the direction that it chimed. I kept on like that to the far side of the park, where the tuning fork pointed directly at a building that had once been some kind of manufacturing facility, perhaps, but now stood abandoned.

The lower floor was dominated by a pair of garage doors and a boarded-up front door. On the lower two floors, most of the windows had been boarded up. On the third floor, truly bored or determined vandals had pitched stones through those windows, and their shattered edges stood sharp and dusty against the blackness behind them, like dirty ice.

I took two more readings, from fifty feet on either side of the first. All pointed directly to the building. It glowered down at me, silent and spooky.

I shivered.

I would be smart to call Michael. Maybe even Murphy. I could get to a phone, try to get in touch with them. It wouldn't take them long to get here.
