I’m not looking at Steve, but I can feel him motionless and watching me. I can’t tell what’s in his head. Steve’s a good guy, but he’s a people-pleaser. With me gone, he could fit right into the squad, if he felt like it. One of the lads, working the decent cases and having a laugh, easy as that.

‘The money’s great,’ I say. ‘And in there, being a woman would actually be a plus. That’s what a lot of these guys want for their wives, daughters: women bodyguards. For themselves, too. Less obvious.’

Steve says, ‘Are you gonna ring him?’

I pull up at the top of Viking Gardens. The cloud’s broken up enough that light leaks through, a thin skin of it coating the slate roofs, the leaning lamppost. It’s the most sunlight we’ve seen all week.

I say, ‘I don’t know.’

I already know Viking Gardens. I live a ten-minute walk away – because I like Stoneybatter, not because I can’t afford anything fancier – and one of the routes I use for my run goes past the top of the road. It’s less exciting than it sounds: a scruffy cul-de-sac, lined with Victorian terraced cottages fronting straight onto patched-up pavements. Low slate roofs, net curtains, bright-painted doors. The street is narrow enough that the parked cars all have two tyres on the kerb.

This is about as long as we can get away with not ringing Breslin, before he shows up at work and the gaffer wants to know what he’s doing there. Before we get out of the car, I ring his voicemail – which may or may not buy us a few extra minutes, but at least it saves me making chitchat – and leave a message. I make the case sound boring as shite, which doesn’t take much, but I know that won’t slow him down. Breslin likes thinking he’s Mr Indispensable; he’ll show up just as fast for a shitty domestic as he would for a skin-stripping serial killer, because he knows the poor victim is bollixed until he gets there to save the day. ‘Let’s move,’ I say, swinging my satchel over my shoulder.

Number 26 is the one down the far end of the road, with the crime-scene tape and the marked car and the white Technical Bureau van. A cluster of kids hanging about by the tape scatter when they see us coming (‘Ahhh! Run!’ ‘Here, missus, get him, he robs Toffypops out of the shop—’ ‘Shut the fuck up, you!’) but we still get watched all the way down the road. Behind the net curtains, the windows are popping questions like popcorn.

‘I want to wave,’ Steve says, under his breath. ‘Can I wave, yeah?’

‘Act your age, you.’ But the shot of adrenaline is hitting me, too, no matter how I fight it. Even when you know trained chimps could do your job that day, the walk to the scene gets you: turns you into a gladiator walking towards the arena, a few heartbeats away from a fight that’ll make emperors chant your name. Then you take a look at the scene, your arena and your emperor go up in smoke, and you feel shittier than ever.
