I swallowed. The Astors were Chicago's elite crowd. They carried enough clout around the old town to get a bum would-be private investigator put away for a good long time. And they could afford the best of lawyers.

It's a lousy world, Dresden , the cool little voice told me. And the good guys don't win unless they have an expensive attorney, too. You'd be in jail before you could blink.

My mouth twisted into a bitter smile as one of the uniform cops, a woman, noticed me and cast a long frown in my direction. I turned around and started walking the other way.

"Hey," the cop said. I kept walking. "Hey!" she said again, and I heard brisk footsteps on the sidewalk.

I hurried along into the dark, and stepped into the first alley. The shadows behind a pile of crates created an ideal refuge, and I carried the girl into it with me. I crouched there in the darkness, and waited, while the cop's footsteps came near and then passed on by.

I waited in the dark, and felt all the heaviness and darkness settle into my skin, into my flesh. The girl just shivered and lay against me, unmoving.

"Just leave me," she said, finally. "Go over the bridge. It will let you cross the bridge if I'm not with you."

"Yes," I said.

"So go on. I'll walk up to the police after you're gone. Or something."

She was lying. I'm not sure how I could tell, but I could.

She would go to the bridge.

I'm told that bravery is doing what you need to do, even when you're afraid. But sometimes I wonder if courage isn't a lot more complicated than that. Sometimes, I think, courage is pulling yourself up off the ground one more time. Doing one more set of paperwork, even when you don't want to. Maybe that's just plain stubbornness, I don't know.

It didn't matter. Not to me. I'm a wizard. I don't really belong here. Our world sucks. It might suit the trolls and the vampires and all those nasty, leering things that haunt our nightmares (while we clutch our physics books to our chests and reassure ourselves that they cannot exist), but I'm not a part of it. I won't be a part of it.

I took a breath, in the dark, and asked, "What's your name?"

She was silent for a moment, and then said, in a very uncertain voice, "Faith."

"Faith," I said. I smiled, so that she could hear it. "My name's Harry Dresden."

"Hi," she said, her voice a whisper.

"Hi. Have you ever seen something like this?" I cupped my hand, summoned some of the last dregs of my power, and cast a warm, glowing light into the ring on my right hand. It lit Faith's face, and I could see on her smooth cheeks the streaks of the tears I had not heard.

She shook her head.

"Here," I said, and took the ring from my finger. Then slipped it onto hers, over her right thumb, where it hung a bit loose. The light died away as I did it, leaving us in the dark again. "Let me show you something."

"Battery went out," she mumbled. "I don't have money for another one."

"Faith? Do you remember the very best day of your life?"

She was quiet for a minute. Then she said, her voice a bare whisper, "Yes. A Christmas. When Gremma was still alive. Gremma was nice to me."

"Tell me about it," I urged, quietly, and covered her hand with my own.

I felt her shrug. "Gremma came over Christmas Eve. We played games. She would play with me. And we stayed up, on the floor by the Christmas tree, waiting for Santa Claus. She let me open just one present, for Christmas eve. It was one she'd gotten me."

Faith took a shuddering breath. "It was a dolly. A real baby—dolly. Mother and Father had gotten me Barbie stuff, the whole line for that year. They said that if I left them all in the original boxes that they would be worth a lot of money, later. But Gremma listened to what I really wanted." Then I heard it, the tiny smile in her voice. "Gremma cared about me."

I moved my hand, and a soft, pinkish light flowed up out of the ring around her thumb, a loving, gentle warmth. I heard Faith draw in a little gasp of surprise, and then a delighted smile spread over her mouth.

"But how?" she whispered.

I gave her a smile. "Magic," I said. "The best kind. A little light in the dark."

She looked up at me, studying my face, my eyes. I shied away from the perception of that gaze. "I need to go back, don't I?" she asked.

I brushed a stray bit of hair from her forehead. "There are people who love you, Faith. Or who one day will. Even if you can't see them beside you, right here, right now, they're out there. But if you let the dark get into your eyes, you might never find them. So it's best to keep a little light with you, along the way. Do you think you can remember that?"

She nodded up at me, her face lit by the light from the ring.

"Whenever it gets too dark, think of the good things you have, the good times you've had. It will help. I promise."

She leaned against me and gave me a simple, trusting hug. I felt my cheeks warm up as she did. Aw, shucks.

"We need to go," I told her. "We've got to get across the bridge and meet my friend Nick."

She chewed on her lip, her expression immediately worried. "But the troll."

I winked. "Leave him to me."

The girl didn't feel anywhere near so heavy as I carried her back. I studied the bridge as we approached. Maybe, if I was lucky, I'd be able to sprint across without the troll being able to stop me.

Yeah. And maybe one day I'd go to an art museum and become well-rounded.

Bridges are a troll's specialty. Whether because of some magic or just because of aptitude, you never get across the bridge without facing the troll. That's life, I guess.

I set the girl down on the ground next to me, and stepped out onto the bridge. "All right, Faith," I said. "Whatever happens, you run across that bridge. My friend Nick is going to pull up on the far side any minute now."

"What about you?"

I gave her a casual roll of my neck. "I'm a wizard," I said. "I can handle him."

Faith gave me another look of supreme skepticism, and fumbled to hold my hand. Her fingers felt very small and very warm inside of mine, and a fierce surge of determination coursed through me. No matter what happened, I would let no harm come to this child.

We walked out onto the bridge. The few lights that had been burning brightly earlier were gone. Gogoth's work, doubtless. Night reigned over the bridge and the Chicago river gurgled by, smooth and cold and black below us.

"I'm scared," Faith whispered.

"He's just a big bully," I told her, "Face him down and he'll back off." Which I hoped, very much, was true. We kept walking and skirted wide around the manhole at the apex of the bridge, me keeping my body between Faith and the entrance to the troll's lair.

Gogoth must have been counting on that.

I heard Faith scream again and whirled my head to see the troll's thick, hairy arm stretched up over the edge of the bridge, while the troll clung to its side like some huge and overweight spider. I snarled and stomped his fingers once more, and the troll bellowed in rage. Faith slipped free and I half-hurled her towards the far side of the bridge. "Run, Faith!"

The troll's arm swept my legs out from beneath me and it came surging up over the railing at the side of the bridge, too supple and swift for its bulk. Its burning eyes focused on the fleeing Faith, and more of its slimy drool spattered out of its mouth. It scythed its cleaver through the air and crouched to leap after the child.

I got my feet under me, screamed, and threw myself at the troll's leg, swinging my long legs around to tangle with the creature's. It roared in fury and went down in a tumble with me. I heard myself cackling and decided, without a doubt, that I had at least one screw loose.

The troll caught me by the corner of my jacket and threw me against the railing hard enough to make me see stars.
