In the intervening months, she'd called me in for work several times, and I'd given the best service I could. But it had been cool between us. Professional. Maybe it was time to try to bridge that gap again.

"Look, Murph," I said. "We've never really talked about what happened, last spring."

"We didn't talk about it while it was happening," she said, her tone crisp as autumn leaves. "Why should we start now? That was last spring. It's October."

"Give me a break, Murphy. I wanted to tell you more, but I couldn't."

"Let me guess. Cat had your tongue?" she said sweetly.

"You know I wasn't one of the bad guys. You have to know that by now. Hell's bells, I risked my neck to save you."

Murphy shook her head, staring straight forward. "That's not the point."

"No? Then what is?"

"The point, Dresden, is that you lied to me. You refused to give me information that I needed to do my job. When I bring you in on one of my investigations, I am trusting you. I don't just go around trusting people. Never have." She took a grip on the steering wheel, her knuckles whitening. "Less than ever, now."

I winced. That stung. What's worse, she was in the right. "Some of what I knew … It was dangerous, Murph. It could have gotten you killed."

Her blue eyes fixed on me with a glare that made me lean back against the car door. "I am not your daughter, Dresden," she said, in a very soft, calm voice. "I am not some porcelain doll on a shelf. I'm a police officer. I catch the bad guys and I put their asses away, and if it comes down to it, I take a bullet so that some poor housewife or CPA doesn't have to." She got her gun out of its shoulder holster, checked the ammo and the safety, and replaced it. "I don't need your protection."

"Murphy, wait," I said hastily. "I didn't do it to piss you off. I'm your friend. Always have been."

She looked away from me as an officer with a flashlight walked past the car, shining the light about on the ground as he looked for exterior evidence. "You were my friend, Dresden. Now …" Murphy shook her head once and set her jaw. "Now, I don't know."

There wasn't much I could say to that. But I couldn't just leave things there. In spite of all the time that had gone by, I hadn't tried to look at things from her point of view. Murphy wasn't a wizard. She had almost no knowledge of the world of the supernatural, the world that the great religion of Science had been failing to banish since the Renaissance. She had nothing to use against some of the things she encountered, no weapon but the knowledge that I was able to give her—and last spring I had taken that weapon away from her, left her defenseless and unprepared. It must have been hell for Murphy, to daily place herself at odds with things that didn't make any sense, things that made forensics teams just shake their heads.

That's what Special Investigations did. They were the team specially appointed by the mayor of Chicago to investigate all the "unusual crimes" that happened in the city. Public opinion, the Church, and official policy still frowned at any references to magic, the supernatural, vampires, or wizards; but the creatures of the spirit world still lurked about, trolls under bridges, cradle-robbing faeries, ghosts and spooks and boogers of every kind. They still terrorized and hurt people, and some of the statistics I'd put together indicated that things were only getting worse, not better. Someone had to try to stop it. In Chicago or any of its sprawling suburbs, that person was Karrin Murphy, and her SI team.

She had held the position longer than any of her many predecessors—because she had been open to the idea that there might be more than was dreamt of in Horatio's books. Because she used the services of the country's only wizard for hire.

I didn't know what to say, so my mouth just started acting on its own. "Karrin. I'm sorry."

Silence lay between us for a long, long time.

She gave a little shiver, finally, and shook her head. "All right," she said, "but if I bring you in on this, Harry, I want your word. No secrets, this time. Not to protect me. Not for anything." She stared out the window, her features softened in the light of the moon and distant streetlights, more gentle.

"Murphy," I said, "I can't promise that. How can you ask me to—"

Her face flashed with anger and she reached for my hand. She did something to one of my fingers that made a quick pain shoot up my arm, and I jerked my hand back by reflex, dropping the keys. She caught them, and jammed one of them in the ignition.

I winced, shaking my stinging fingers for a moment. Then I covered her hand with mine.

"Okay," I said. "All right. I promise. No secrets."

She glanced at me, at my eyes for a breath, and then looked away. She started the car and drove from the parking lot. "All right," she said. "I'll tell you. I'll tell you because I need every bit of help I can get. Because if we don't nail this thing, this werewolf, we're going to have another truckload of corpses on our hands this month. And," she sighed, "because if we don't, I'm going to be out of a job. And you'll probably end up in jail."

"Jail?" I said. "Jail? Hell, Murphy. Were you planning on mentioning this to me anytime soon?"

She shot me an irritated scowl, headlights of cars going the opposite way on the highway flaring across her face. "Don't even start with me, Harry. I've had a long month."

A dozen questions tried to fight their way out of my mouth. The one that ended up winning was, "Why didn't you call me in on the other killings, last month?"

Murphy turned her eyes back to the road. "I wanted to. Believe me. But I couldn't. Internal Affairs started riding me about what happened with Marcone and Victor Sells last spring. Someone got the idea that I was in cahoots with Marcone. That I helped to murder one of his competitors and took out the ThreeEye drug ring. And so they were poking around pretty hard."

I felt an abrupt twinge of guilt. "Because I was on the scene. You had that warrant out for me and then had it rescinded. And then there were all those rumors about me and Marcone, after the whole thing was over …"

Murphy's lips compressed, and she nodded. "Yeah."

"And if you'd have tried to tell me about it, it would have been throwing gasoline on the fire." I rubbed at my forehead. And it would have gotten me looked at harder, too, by whoever was investigating Murphy. She had been protecting me. I hadn't even considered what those rumors Marcone had spread might do to anyone besides myself. Way to go, Harry.

"One thing you're not is stupid, Dresden," she confirmed. "A little naive, sometimes, but never stupid. IA couldn't turn anything up, but there are enough people who are certain I'm dirty that, along with the people who already don't like me, they can screw me over pretty hard, given the chance."

"That's why you didn't make an issue out of what Agent Benn did," I guessed. "You're trying to keep everything quiet."

"Right," Murphy said. "I'd get ripped open from ass to ears if IA got word of me so much as bending the rules, much less tussling with one of the bureau's agents. Believe me, Denton might look like a jerk, but at least he isn't convinced that I'm dirty. He'll play fair."

"And this is where the killings come in. Right?"

Instead of answering, she cut into the slow lane and slowed to a leisurely pace. I half turned toward her in my seat, to watch her. It was while I did this that I noticed the headlights of another car drift across a couple lanes of traffic to drop into the slow lane behind us. I didn't say anything about it to Murphy, but kept a corner of my eye on the car.

"Right," Murphy said. "The Lobo killings. They started last month, one night before the full moon. We had a couple of gangbangers torn to pieces down at Rainbow Beach. At first, everyone figured it for an animal attack. Bizarre, but who knew, right? Anyway, it was weird, so they handed the investigation to me."
