“He’s weird, yeah. He’s not Jesus. He’s not here to give his life for Pat Spain’s sins.”

Richie said, “It’s not just him that’s weird. What about the baby monitors? Those weren’t your man Conor’s doing. And the holes in the walls? There was something going on inside that house.”

I leaned back against the wall with a thump and folded my arms. It might have been just the fatigue, or the thin yellowy-gray dawn smearing the window, but that champagne fizz of victory was well and truly gone. “Tell me, old son: why the hate for Pat Spain? Is this some kind of chip on your shoulder, because he was a good solid pillar of the community? Because if it is, I’m warning you now: get rid of it, sharpish. You’re not always going to be able to find a nice middle-class boy to pin things on.”

Richie came at me fast, finger pointing; for a second I thought he was going to jab me in the chest, but he had enough sense left to stop himself. “It’s got nothing to do with class. Nothing. I’m a cop, man. Same as yourself. I’m not some thicko skanger you brought in as a favor because it’s Take A Knacker To Work Day.”

He was too close and much too angry. I said, “Then act like a cop. Step back, Detective. Get a grip on yourself.”

Richie stared me out of it for another second; then he wheeled away, flung himself back against the glass and shoved his hands deep into his pockets. “You tell me, man: why are you so dead set that it isn’t Patrick Spain? Why the love?”

I had no obligation to explain myself to some jumped-up little newbie, but I wanted to; I wanted to say it, shove it deep into Richie’s head. “Because,” I said, “Pat Spain followed the rules. He did everything people are supposed to do. That’s not how killers live. I told you from the start: things like this don’t come out of nowhere. All that crap the families give the media—‘Oh, I can’t believe he would do this, he’s such a Boy Scout, never done anything bad in his life, they were the happiest couple in the world’—that’s garbage. Every time, Richie, every single time, it turns out that the guy was a Boy Scout except for a record as long as your arm, or he’d never done anything bad except for his little habit of terrorizing the shit out of his wife, or they were the happiest couple in the world except for the minor fact that he was banging her sister. There’s not one hint, anywhere, that any of that applied to Pat. You’re the one who said it: the Spains did their best. Pat was a trier. He was one of the good guys.”

Richie didn’t move. “Good guys break.”

“Seldom. Very, very seldom. And there’s a reason for that. It’s because the good guys have stuff to hold them in place, when the going gets tough. They’ve got jobs, families, responsibilities. They’ve got the rules they’ve been following their whole lives. I’m sure all that stuff sounds uncool to you, but here’s the fact: it works. Every day, it keeps people from crossing over the line.”
