"Not one," she said. "Three. Three , Mr. Dresden. I only got one vision when they tried to kill the President. I got two for that disaster at NASA, and for the earthquake inLaos . I've never had three before. Never had something appear so clearly …"

I closed my eyes to think about this. Again, my instincts told me to help the girl, smash the bad ghost or whatever, and walk off into the sunset. If she was indeed afflicted with Cassandra's Tears, my actions could do more than save her life. My faith could change it for the better.

On the other hand, I'd been played for a sucker before. The girl was obviously a competent actress. She had shifted smoothly to the role of willing seductress, when she thought I had been asking for sex in payment. That she would immediately make that conclusion based on my own fairly neutral statement said something about her, all by itself. This wasn't a girl who was used to playing things fair and square. Unless I was grossly misreading her, she had bartered sex for goods and services before-and she was awfully young to be so jaded about the entire matter.

The entire Cassandra's Tears angle was a perfect scam, and people had used it before, among the circles of the magically endowed. The story required no proof, no performance on the part of the person running the scam. All she would need would be a smidgen of talent to give her the right aura, maybe enough kinetomancy to tilt the dice a little on their way down. Then she could make up whatever story she wanted about her supposed prophetic gifts, put on a little-girl-lost act, and head straight for the local dummy, Harry Blackstone Copperfield Dresden.

I opened my eyes to find her watching me. "Of course," she said. "I could be lying. Cassandra's Tears can't be analyzed or observed. I could be using it as an excuse to provide a reasonable explanation why you should help a lady in distress."

"That's pretty much what's going through my mind,Lydia , yeah. You could just be a small-time witch who stirred up the wrong demon and is looking for a way out."

She spread her hands. "All I can tell you is that I'm not. I know that something's coming. I don't know what, and I don't know why or how. I just know what I see."

"Which is?"

"Fire," she whispered. "Wind. I see dark things and a dark war. I see my death coming for me, out of the spirit world. And I see you at the middle of it all. You're the beginning, the end of it. You're the one who can make the path go different ways."

" That'syour vision? Iowa has less corn."

She turned her face away. "I see what I see."
