"Leonid Kravos!" I thundered. I repeated the name, and saw Lydia's eyes fly open wide in shock. "Begone, Kravos! You second-rate firecaller! Begone! Begone!" And with the last word, I stamped my foot down, releasing the power of the exorcism down, into the earth.
Lydia screamed, her body arching, her mouth dropping open wide. Within the whirling vortex, glittering motes of silver and gold light gathered into a funnel, centered on Lydia's gaping mouth. Scarlet energy flooded out of her screaming mouth, and for a moment there was an unnerving overlap of screams - one high-pitched, young, feminine, terrified, while the other was inhuman, otherworldly. More scarlet light lashed forth from Lydia's eyes, stolen away by the vortex's power.
And then with a rush and an implosion of suddenly empty air, the vortex swirled into an infinitely thin line and vanished, dropping down into the floor, lower, deep into the earth.
Lydia let out a low, exhausted cry, and dropped limply to the floor. Thomas, still clutching her, tumbled down with her. Silence fell on the room, but for the four of us, gasping for breath.
Finally, I managed to sit up. "Michael," I called, my voice hoarse. "Michael. Are you okay?"
"Did you stop it?" he asked. "Is the girl all right?"
"I think so."
"Thank God," he said. "It kicked me, got one of my ribs. I'm not sure I can sit up."
"Don't," I said, and mopped sweat from my brow. "Broken ribs could be bad. Thomas? Are you - Hey! What the hell do you think you're doing?"
Thomas lay with his arms around Lydia, his pale, naked body pressed against hers, his lips nuzzling her ear. Lydia's eyes were open, colored naturally again, but not focused on anything. She didn't look conscious, but she was making tiny, aroused motions of her body, her hips, leaning back to him. Thomas blinked up at me when I spoke, eyes still empty and white.
"What?" he asked. "She's not unwilling. She's probably just grateful to me, for my help."
"Get away from her," I snapped.
"I'm hungry," he said. "It won't kill her, Dresden. Not the first time. You'd be dead right now without me. Just let me - "
"No," I said.
"But - "
"No. Get off of her, or you and I are going to have words."
A snarl split the air between us, Thomas's full lips peeling back from his teeth. They looked like human teeth, not vampire fangs. Whiter and more perfect than human teeth, but other than that, normal.
I returned his stare coolly.
Thomas looked away first. He closed his eyes for a moment, and when he opened them again, there were pale rings of color in them once more, slowly darkening. He released Lydia and rolled away from her. His ribs still looked dented, but not as much as before. He got to his feet and wrapped the towel around his hips again, then stalked back toward the bathroom without another word.
I checked Lydia's pulse, blushed, and tugged her shorts back into place. Then I righted the couch and put her back onto it, beneath the blankets. After that, I went to Michael.
"What was that all about?" he asked.
I told him what had happened, in terms as PG rated as possible. He scowled, flicking a glance back toward the bathroom. "They're like that. The White Court. Seducers. They feed on lust, fear, hatred. Emotions. But they always use lust to seduce their victims. They can force them to feel it, indulge in sex. It's how they feed."
"Sex vampires, I know," I muttered. "Still. It's interesting."
"Interesting?" Michael sounded skeptical. "Harry, I wouldn't call it interesting."
"Why not?" I said. I squinted after Thomas, thoughtfully. "Whatever he used, it worked on the Nightmare. Caught it up. That means that it's either some kind of ambient magic, maybe that cold I felt, that works on everything around, or else it's something chemical - like Red Court venom. Something that got to Lydia's body and bypassed the Nightmare's control of her mind, altogether. Pheromones, maybe."
"Harry," Michael said, "I really don't mean to discourage your scholarly pursuits, but would you mind, very much, helping me with these broken ribs."
We took inventory. I had some nasty bruises on my throat, but nothing more. Michael had one rib that was definitely broken, and one more that might have been cracked, tender as it was. I got him wrapped up pretty well. Thomas came out of my room, dressed in some of my spare jogging clothes. They hung off of him, and he had to roll the sleeves and legs of the sweatpants up. He slouched into a chair, his gaze settling on Lydia's sleeping form with a rather disconcerting intensity.
"It all fits now," I told them. "I know what's going on, so I can finally do something about it. I'm going to go to the town house, and get everyone out."
Michael frowned at me. "What fits?"
"It wasn't the demon that crossed over, Michael. We were never fighting the demon. It was Kravos himself. Kravos is the Nightmare."
Michael blinked at me. "But we didn't kill Kravos. He's still alive."
"Dollars to donuts he isn't. I figure the night before the Nightmare's attacks started, he puts together a ritual and takes himself out."
"Why would he do that?"
"To come back as a ghost. To get revenge. Think about it - that's all the Nightmare has been doing. It's been rampaging around, avenging Kravos."
"Could he do that?" Michael asked.
I shrugged. "I don't see why he couldn't, if he had raised a bunch of power, and if he was focused on getting his vengeance and turning himself into a ghost. Especially ..."
"... with the border to the Nevernever as turbulent as it was," Michael finished.
"Exactly. Which means that Mavra and Bianca helped him out, specifically. Hell, they probably put together the ritual that he used. And if someone in federal custody here in Chicago suddenly turned up suicided in his cell, it would cause a big stir in local police - and would be serious news for the media. Which is why Murphy was being so hush-hush, and Susan was so distracted. She was working on a story, finding out what happened. Following up a rumor, maybe."
Thomas frowned. "Let me get this straight. This Nightmare is the ghost of the sorcerer Kravos. The cult murderer in the news several months ago."
"Yeah. The turbulence in the Nevernever let him get made into a badass ghost."
"Turbulence?" Thomas said.
I nodded. "Someone began binding the local spooks with torment spells. They went wild and started stirring the border between the real world and the Nevernever. I figure it was Mavra, working with Bianca. That same turbulence let Kravos hit everyone he could in their dreams. It's how he got to me, and how he got to poor Malone, and how he got to Lydia just now. Lydia knew what he was doing. That's why she never wanted to go to sleep. I didn't see it coming, when he hit me in my dreams. I wasn't ready for a fight, and he kicked my ass."
