Steve has wandered over to the water cooler and is filling a plastic cup, watching us. Breslin lifts a hand. ‘Whoa whoa whoa. Let’s just stall the ball here. Are you saying you’ve got doubts?’

‘I’m saying I’d like your opinion. If that’s a problem, though, I can live without it.’ I’m right back to wanting to throat-punch the bollix. The fine thread of alliance that built up between the two of us in the interview room lasted all of thirty seconds outside it.

‘Talk to me, Conway. Are you trying to be super-careful, yeah? Make sure you’ve got all your bases covered? Is that what’s going on?’

It’s not a bad technique – make the other person explain herself, you’ve got her on the back foot right there – but this is what I mean about Breslin not being as smart as he thinks: I just saw him use it on Rory, plus it should have occurred to him that, what with me being a detective, I might just know the same tricks he does. I lean a shoulder against the one-way glass, where I can keep one eye on Rory, and stick my hands in my pockets. ‘Do you think we should be?’

Breslin sighs. ‘Well. I guess we’ve got to face it: one of the last things your rep needs is a ding for jumping the gun. But the other last thing you need is a rep for being so indecisive that you’ll let your guy walk rather than put your balls on the line. Are you getting me?’

Steve says, doing mildly bewildered, ‘Hang on a sec. You’re saying you deffo think he did it, yeah?’

Breslin sighs exasperatedly and runs his hands over what’s left of his hair, carefully so he won’t bother it. ‘Well, yeah, Moran. I kind of do. This guy was the victim’s boyfriend, so that’s Strike One. He was actually at the crime scene at the relevant time, he’s not even trying to deny it, so that’s Strike Two. He was wearing non-fibre gloves, same as our killer: Strike Three. He was wearing a black wool overcoat, and we’ve got black wool fibres on the body: Strike Four. And he basically admits that he was getting impatient for his ride, after all the time and money he’d put into this girl, and she wasn’t showing any signs of giving up the goods. That’s a great big Strike Five. I’m not a baseball aficionado, but I’m pretty sure it takes less than that to put a guy well and truly out.’

Steve is sipping his water and nodding through Breslin’s list. ‘I’d say it does, all right,’ he says agreeably. His accent has got stronger. I put on the Thicko Skanger act too, now and then, but I do it for suspects, not for my own squad. Sometimes Steve makes me want to puke. ‘I think I’ll keep an open mind a little longer, but.’
