Hendricks glanced up at him. He was kneeling behind the victim’s head and lifting it so that it was resting against his legs.

‘Brigstocke gave me the option.’

‘More fool you.’

‘I could have let Kitson take it.’

‘This one’s got your name on it,’ Hendricks said.

‘Why?’

‘Look at her, Tom.’

Emily Walker was… had been early thirties or thereabouts, dark hair streaked with a little grey and a small star tattooed above one ankle. She was no more than five feet tall, her height emphasising the few extra pounds which, judging by the contents of the fridge and the magnet on the door that said ‘ARE YOU SURE YOU’RE HUNGRY?’, she was trying to lose. She wore a thin necklace of brown beads and there was a charm bracelet around one wrist: dice, a padlock, a pair of fish. Her shirt was denim. Her skirt was thin cotton, the same pillar-box red as the varnish on her toenails.

Thorne looked across at the sandal that had been circled on the lino close to the fridge. At the decorative bottle a few feet away, with what looked like balsamic vinegar on the inside and blood and hair caught in a few of the glass ridges on the outside, and beyond, to the light still winking on the front of the washing machine. His hand drifted up to his face, fingers moving along the straight, white scar on his chin. He stared until the red light began to blur, then turned and wandered away, leaving Hendricks cradling Emily Walker’s head and talking quietly into his Dictaphone.

‘There is nothing holding the plastic bag in position over the victim’s head. Assume that the killer kept it in place around the victim’s neck with his hands. Bruises on neck suggest he held it there with a great deal of force until the victim had stopped breathing…’

Holland was standing out on the patio at the rear of the house, watching half a dozen uniforms combing the flower beds. There were arc-lamps out here too, but this was only an initial sweep and more officers would be back at first light to conduct a fingertip search.

‘So, no forced entry then,’ Thorne said.

‘Which means she knew him.’

‘Possibly.’ Thorne could smell cigarettes on Holland, wanted one himself for a second or two. ‘Or she answered the door and he produced a weapon, forced her back inside.’

Holland nodded. ‘Let’s see if we get lucky with the house to house. Looks like the kind of street where there’s plenty of curtain-twitching.’

‘What about the husband?’

‘I only had five minutes before they took him to a hotel up the road,’ Holland said. ‘In pieces, much as you’d expect.’

‘Trying too hard, you reckon?’

‘How d’you mean?’

‘Sounds like he wanted everyone in the street to see just how upset he was. After he’d called us.’

‘You heard the 999 tape?’

‘No.’ Thorne shrugged. ‘Just…’

‘Just wishful thinking?’ Holland said. ‘Right?’

‘Yeah, maybe.’ It was getting a little chillier. Thorne shoved his hands inside the plastic suit and down into the pockets of his leather jacket. ‘Be nice if it was… a simple one.’

‘I can’t see it,’ Holland said.

Nor could Thorne, if he were being honest. He knew only too well how domestic violence could escalate; had seen the ways a jealous boyfriend or a domineering husband could lose it. He blinked, saw the flop of the arm as the body was turned. Spots of pillar-box red against black-and-white squares. Not a simple one…

‘Maybe he was just that upset,’ Holland said. ‘How many of these have we done?’

Thorne puffed out his cheeks. There was no need to answer.

‘Right. And I still can’t imagine what it must be like. Not even close.’

Holland was fifteen years younger than Thorne. He had been working alongside him for more than seven years and though the fresh-faced newbie was long gone, Thorne still relished the glimpses of someone who hadn’t been totally reshaped by the Job. Holland had looked up to him once, had seen him as the kind of copper he would like to become, Thorne knew that. He knew equally that Holland was not the same as he was… not where it mattered, and that he should be bloody grateful for it.

‘Especially when it’s a woman,’ Holland said. ‘You know? I see the husbands and boyfriends and fathers, how it hits them, and it doesn’t matter if they’re hysterical or furious or sitting there like zombies. I’ve got no bloody idea what’s happening inside their heads.’

‘Don’t knock it, Dave,’ Thorne said.

They both looked across at laughter from further down the garden, where one of the officers had obviously stepped in something. Watched as he scraped the sole of his shoe across the edge of the lawn.

‘So, where were you skiving off to earlier, then?’ Holland asked.

‘Sorry?’

‘When all this kicked off.’

Thorne cleared his throat.

Louise had been fine about him taking the job on, when he’d popped into the hospital to drop off her stuff. She was already in bed, working her way through a copy of heat and trying to tune out the incessant chatter of a woman in the bed opposite. He’d asked if she was sure. She’d looked at him like he was being stupid and asked why she wouldn’t be. He’d told her to call if she wanted anything, if she needed him. She’d told him not to worry and said that she could get a taxi back when it was all over, if she had to.

‘Dentist,’ Thorne said. ‘An hour with the Nazi hygienist. The woman’s like something out of Marathon Man. ’

Holland laughed. Said, ‘Is it safe?’

‘I’m telling you.’

‘They remade that film, you know?’ Holland waited for Thorne to take the bait and look at him. ‘But they had to call it Snickers Man.’ He laughed again, seeing that Thorne was doing his best not to.

‘You told Sophie you’re back on the fags?’ Thorne asked.

Holland shook his head. ‘Got a glove compartment full of extra-strong mints.’ He leaned down and spat into a drain. ‘Stupid really, ’cause I’m bloody sure she knows. Just doesn’t want a row, I suppose.’

Holland and his girlfriend were another couple who had been talking about getting out of London, and about Holland giving up the Job. Thorne wondered if that was something else that was not being mentioned for fear of reigniting an argument. He had always been convinced that Holland should stay where he was, but he would never have said so. If Sophie so much as got wind of Thorne’s opinion, she would fight tooth and nail to do the opposite.

So he kept his mouth shut, content that Holland was still there.

‘We’ll get the official ID done first thing in the morning,’ Thorne said. ‘Then bring the husband in for a chat.’

‘Fair enough.’

‘You never know, we might get lucky.’

Holland snorted, nodded across to where the uniformed officer was now working at the sole of his shoe with a twig, flicking out the shit. ‘That kind of lucky,’ he said.

They both looked up as a plane passed low overhead, lights blinking, on its way to Luton. Thorne watched it move fast across a clear sky and swallowed hard. Eight weeks earlier, he and Louise had gone to Greece together for their first proper holiday as a couple. They had spent most days lying by a pool reading trashy books and done nothing more culturally demanding than work out how to ask for beer and grilled squid in the local taverna. They’d both tried hard not to talk about work and had laughed a lot. One day, Louise had rubbed cream into Thorne’s shoulders where he’d got burned, and said, ‘This is as far as it goes for me in terms of non-sexual intimate contact, all right? I’m not into squeezing other people’s blackheads and I will not be wiping your arse if you break both your arms.’

She’d bought the pregnancy testing kit on their final morning there. Used it just before they’d gone out to dinner that last night.

Thorne was sitting in the car when Hendricks came out.

He’d checked his phone and tried both flats, but Louise hadn’t got back yet and there were no messages. He’d listened to the radio for a while then called again to no avail. Louise’s mobile was switched off and Thorne guessed it was too late to ring the hospital.
