‘Can’t wait to meet him,’ I say. ‘Bet he was gone before anyone showed up, yeah?’

‘Oh yeah. When the ambulance got there, the door was locked, no one answering. Uniforms arrived and broke it in, found a woman in the sitting room. Head injuries. Paramedics confirmed she was dead. No one else home, no sign of forced entry, no sign of burglary.’

‘If the guy wanted an ambulance, why’d he ring Stoneybatter station? Why not 999?’

‘Maybe he thought 999 would be able to track down his phone number, but a cop shop wouldn’t have the technology.’

‘So he’s a bloody idiot,’ I say. ‘Great.’ O’Kelly was right about the quays: the Department for Digging Up Random Shit is going at one lane with a jackhammer, the other one’s turned into a snarl that makes me wish for a vaporiser gun. ‘Let’s have the lights.’

Steve scoops the blue flasher out from under his seat, leans out the window and slaps it on the roof. I hit the siren. Not a lot happens. People helpfully edge over an inch or two, which is as far as they can go.

‘Jesus Christ,’ I say. I’m in no humour for this. ‘So how come the uniforms think it’s a domestic? Anyone else live there? Husband, partner?’

Steve scans again. ‘Doesn’t say.’ Hopeful sideways glance at me: ‘Maybe they got it wrong, yeah? Could be something good after all.’

‘No, it’s fucking not. It’s another fucking domestic, or else it’s not even murder, she died from a fucking fall just like the caller said, because if there was a snowball’s chance in hell that it was anything halfway decent, O’Kelly would’ve waited till the morning shift got in and given it to Breslin and McCann or some other pair of smarmy little— Jesus!’ I slam my fist down on my horn. ‘Do I have to go out there and arrest someone?’ Some idiot up at the front of the traffic jam suddenly notices he’s in a car and starts moving; the rest get out of my way and I floor it, round onto the bridge and across the Liffey to the north side.

The sudden semi-quiet, away from the quays and the workmen, feels huge. The long runs of tall red-brick buildings and shop signs shrink and split into clusters of houses, give the light room to widen across the sky, turning the low layer of clouds grey and pale yellow. I kill the siren; Steve reaches out the window and gets the flasher back in. He keeps it in his hands: scrapes a smear of muck off the glass, tilts it to make sure it’s clean. Doesn’t go back to reading.

Me and Steve have known each other eight months, been partnered up for four. We met working another case, back when he was on Cold Cases. At first I didn’t like him – everyone else did, and I don’t trust people who everyone likes, plus he smiled too much – but that changed fast. By the time we got the solve, I liked him enough to use my five minutes in O’Kelly’s good books putting in a word for Steve. It was good timing – I wouldn’t have been in the market for a partner off my own bat, I liked going it alone, but O’Kelly had been getting louder about how clueless newbies didn’t fly solo on his squad – and I don’t regret it, even if Steve is a chirpy little bollix. He feels right, across from me when I glance up in the squad room, shoulder to shoulder with me at crime scenes, next to me at the interview table. Our solve rate is up there, whatever O’Kelly says, and more often than not we go for that pint to celebrate. Steve feels like a friend, or something on the edge of it. But we’re still getting the hang of each other; we still have no guarantees.
