The possessed Lydia glided from the path of my punch, caught my wrist, and dumped me onto my back. I started to push myself up, but she threw herself astride me, and slammed my head back against the floor, twice. I saw stars.

Lydia stretched above me, purring, and thrusting her hips down against mine. I tried to escape during the moment of gloating, but my arms and legs just didn't respond. She reached down, laying both of her hands almost delicately on my throat, and murmured, "Such a shame. All this time, and you didn't even know who it was after you. You didn't even know who else wanted revenge."

"I guess sometimes you find out the hard way," I slurred.

"Sometimes," Lydia agreed, smiling. And then her hands closed over my throat, and I didn't have any more air.

Sometimes, when you're facing death, it feels like everything slows down. Everything stands out sharply in detail, almost freezes. You can see it all, feel it all, as though your brain has decided, in sheer defiance, to seize the last few moments of life and to squeeze them for every bit of living left.

My brain did that, but instead of showing me my trashed apartment and how I really needed a new coat of paint on the ceiling, it started frantically shoving puzzle pieces together. Lydia. The shadow demon. Mavra. The torment spells. Bianca.

One thing stood out in my mind, a piece that didn't fit anywhere. Susan had been gone for a day or two, where I had barely been able to talk to her. She'd said she was working on something. That something was happening. It fit, somehow, somewhere.

Stars swam in my vision and fire started to spread through my lungs. I struggled to pry her arms off of me, but it was no use-possessed, she was simply too strong to deal with.

Susan had been asking me about something, some insignificant part of the phone conversation we had, between sexual innuendos. What had it been?

I heard myself making a very slight sound, something like, "Gaghk. Aghk." I tried to lever Lydia's weight up and off of me, but she simply rolled with me, taking my weight onto her and then continuing the motion, slamming me to the floor again. My vision began to darken, though I opened my eyes wide. It was like staring down a dark tunnel, looking up at Lydia's blood-filled eyes.

I saw Michael struggle to his knees, his face white as a fresh dusting of snow. He moved toward Lydia, but she turned her head slightly and kicked him, lashing out with one heel. I heard something else snap as the force of the kick drove Michael back.

Murphy had been distracted about something, too. Something she'd hurriedly changed subjects on. Intuition drew a line between them. And then an equal sign.
