He can’t talk. I lean in even closer and I say, softly and very clearly, ‘The whole thing was a lie. Every time Aislinn kissed you, every time she slept with you, every time she said she loved you, it took everything she had not to puke. She forced herself to go through all that so she’d have her chance to give you what you deserved.’

McCann’s head is down and swaying. His shoulders are hunched like a bleeding animal’s, trying to stay on its feet.

‘Now do you understand why she kept those photos?’

His breathing, like something out of a hospital ward, in the pretty pastel room.

‘You were right: she was going to take them to your wife, if she couldn’t make you leave on your own. One way or another, Aislinn was going to break up your marriage. And then she was going to welcome you with open arms and tell you that your wife never deserved you to begin with and you were better off with someone who’d treat you right. And once the dust settled, once the divorce papers were filed and your kids hated your cheating guts and there was no way your missus would ever let you in the door again, then Aislinn was going to dump you right on your arse and leave you there in the mess that was your brand-new life.’

Nothing, just that thick breathing. This is it. There’s nothing left of McCann; between us and Aislinn, we’ve taken the lot. If he’s going to talk, it’s from this seething nowhere place we’ve brought him to.

Steve says quietly, ‘You were in love with her. Weren’t you?’

McCann’s head lifts. His eyes move across us like he’s blind. His mouth opens and he takes one shallow breath and holds onto it for a long moment before he says, ‘No comment.’

It stays in the air like a dark spot. The room looks skewed to the point of insane, all those cute colours and smarmy little comforts straining to cover the grinning white interview-room bones – table, chairs, camera, one-way glass – underneath.

Steve says, ‘When you walked in on her getting ready for Rory. Did that hit you out of the blue? Or did you already have your suspicions?’

‘No comment.’

‘Talk to us, man. What did she say? Did she tell you to get out and not come back? Did she laugh at you, for thinking a woman like her could love you? What?’

‘No comment.’

He’s not even trying to look at us, not any more. He’s staring at the wall between our heads, blank-eyed, tuning us out so everything we say is just faraway babble. I’ve seen that look before, on rapists, murderers. The ones we’re never going to break, because they know what they are and they’re not fighting it.

‘Where were you last Saturday evening?’ Steve asks.

‘No comment.’
