And then I had it: the last piece of the puzzle. I knew what had happened, where the Nightmare had come from, why it was after me, in particular. I knew how to stop it, knew what its limits were, how Bianca had enlisted it, and why my spells had been so hard-pressed to affect it.

Almost a pity, really. I'd figured things out just in time to die.

Vision faded altogether.

And a moment later, so did the pain in my throat.

Instead of drifting off into whatever lay beyond, though, I sucked in a breath of air, choking and gasping. My vision became red for a moment, as blood rushed back through my head, and then started to clear.

Lydia still crouched over me, up on her knees, straddling me-but she'd released my throat. Instead, she had arched her arms up and back, over her head, to caress Thomas's naked shoulders.

The vampire had pressed up against Lydia's back. His mouth nuzzled her throat, slow kisses, strokes of his tongue that made the girl shudder and quiver. His hands roamed slowly over her body, always touching skin, fingers roaming up beneath the brief Lycra top to caress her breasts. Lydia gasped, blood-filled eyes distant, unfocused, body responding with a slow, sensual grace.

Thomas looked past her, through the dark fall of his hair, to me. His eyes weren't blue-grey anymore. They were empty, white, no color to them at all. I felt cold coming off of him, something I sensed more than felt on my skin, a horrible and seductive cold. He continued, spreading a line of kisses up Lydia's neck, to her ear, making her whimper and shake.

I swallowed, and crawled back on my elbows, dragging my hips and legs out from beneath the pair of them.

Thomas murmured, so softly that I wasn't sure I'd heard him. "I don't know how long I can distract her, Dresden. Quit gawking and do something. I'll put on afternoon theater for you later, if you want to watch that bad." Then his mouth covered the girl's, and she stiffened, eyes flying open wide before they languidly closed, deepening the kiss.

I flushed at Thomas's words, which made my head pound painfully. I rooted around the floor and recovered the candles, still lit, and the bag of salt. I spread the salt in a circle around Lydia and Thomas, as Lydia drew the Lycra shorts down and reached back to grasp at Thomas, to urge him toward her.

Thomas let out a groan of pure anguish and said, "Dresden. Hurry ."
