I was doing exactly the same thing as Aislinn: getting lost so deep inside the story in my head, I couldn’t see past its walls to the outside world. I feel those walls shift and start to waver, with a rumble that shakes my bones from the inside out. I feel my face naked to the ice-flavoured air that pours through the cracks and keeps coming. A great shiver is building in my back.

Crowley and Steve are both watching me, waiting to see if I’m gonna let Crowley off the hook. Steve’s game is yelping for attention.

‘OK,’ I say. I want to walk out, but I’m not done here. I shove everything else to the back of my mind. ‘OK. We’ll go with that.’

Crowley says – the fear’s vanished; he’s straight back into hyena mode – ‘You mentioned having a bit of news for me.’

‘Oh yeah,’ I say. My focus is back; this is gonna be fun. ‘Have I got a scoop for you. You’re gonna love this.’

Crowley whips out his voice recorder, but I shake my head. ‘Nah. This is non-attributable. It comes from sources close to the investigation. Got it?’ ‘Sources close to the investigation’ means cops. I don’t want McCann and Breslin thinking Lucy’s been talking.

He gets pouty, but I sit back and have a watch of Steve jabbing manically at his phone screen. In the end Crowley sighs and puts the recorder away. ‘I suppose so.’

‘Good man,’ I say, sitting up again. ‘Get a load of this. Aislinn Murray, right?’ Crowley nods, filling up with drool, hoping I’m about to tell him she was raped in creative ways. ‘She was having an affair. With a married guy.’

Crowley’s only delighted to settle for that. He does a man-of-the-world head-shake. ‘I knew she was too good to be true. Knew it. Girls who look like that, my God, they think they can get away with anything. Sometimes – oops, so sorry, Your Highness! – it doesn’t work out like that.’

He’s already rewriting the story in his head, whizzing through his best euphemisms for ‘homewrecking nympho who got what she deserved’. Steve says, ‘It gets better. Guess what her fella does for a living.’

‘Hmmm.’ Crowley pinches his chin and thinks. ‘Well. Obviously a girl like that would have liked money. But I’d hazard a guess that she was even more aroused by power. Would I be right?’

Me and Steve are well impressed. ‘How come you’re not doing our job?’ Steve wants to know. ‘We could do with that kind of smarts on the squad.’

‘Ah, well, not everyone’s the type who can work for The Man, Detective Moran. I think we must be talking about a politician. Let me see . . .’ Crowley steeples his fingers against his lips. He’s got the whole story rolling out in his head, ready for ink. ‘Aislinn’s job wouldn’t have taken her into those circles, so they must have met socially, meaning he’s young enough to be out and about—’
