I wanted to crush the bag in my hand till it crumbled to dust and vanished, till even the image of it was squashed out of my mind. Quigley said, “I knew you’d got thick as thieves, yourself and young Curran, but I never guessed you were sharing that much.” The snigger again. “So I’m wondering, now: did the young lady get this off you, or off Curran?”

Somewhere far inside my mind, one corner was moving again, methodically as a machine. Twenty-five years’ worth of working my arse off to learn control. Friends have slagged me for it, newbies have rolled their eyes when I gave them the speech. Fuck them all. It was worth it, for that conversation on a drafty landing when I held it together. When this case sets its claws scrabbling circles around the inside of my skull, the only thing I have left to tell myself is that it could have been worse.

Quigley was loving this, every second, and I could use that. I heard myself say, cool as ice, “Don’t tell me you forgot to ask her.”

I had been right: he couldn’t resist. “Holy God, the drama. Wouldn’t give me her name, wouldn’t give me any information on where and how she came into possession of this here—when I put the pressure on, just gently, like, she went only hysterical. I’m not joking you: she pulled out a great clump of her hair by the roots, screamed at me that she was going to tell you I’d done it. Now, I wasn’t worried about that—any sensible man would take the word of an officer over the say-so of some young one—but the girl’s mad as a bag of cats. I could have got her talking easily enough, but there was no point: I couldn’t rely on a word she said. I’m telling you, it doesn’t matter how tasty she is, that one belongs in a straitjacket.”

I said, “Shame you didn’t have one handy.”

“I’d have been doing you a favor, so I would.”

The squad-room door slammed open above us and three of the lads headed down the corridor towards the canteen, bitching colorfully about some witness who had suddenly developed amnesia. Quigley and I pressed back against the wall, like conspirators, until their voices faded. I said, “What did you do with her instead?”

“I told her she needed to get a hold of herself and she was free to go, and off she flounced. Gave Bernadette the finger on the way out. Lovely.” With his arms folded and his chins tucked in sourly, he looked like a fat old woman bitching about wanton modern youth. That icy, detached corner of me almost wanted to smile. Dina had scared the shit out of Quigley. Every now and then, the crazy comes in useful. “Your girlfriend, is she? Or a little treat you bought for yourself? How much do you think she’d have wanted for this yoke, if she’d found you this morning?”
