‘How much does it bother you?’ Thorne asked. ‘That nobody’s asking the Mullens for any money. That nobody’s asking for anything.’

‘These cases are never predictable, I’ve learned that much. But yeah, it’s bloody odd.’

‘They’ve had Luke four days already.’

‘Four days, five nights. Mind you, we were worried that they hadn’t got in touch, and then they did.’

Thorne began to do up the buttons on his leather jacket. ‘Something bothers me,’ he said. ‘Something on the tape.’

‘What?’

‘I wish I could tell you. Something’s not right, though; something that he said, or maybe just the way he said it.’

‘It’ll come to you.’

‘Maybe.’

‘It’s old age, mate. That’s Alzheimer’s kicking in.’

Thorne dug down deep for a smile.

‘I’ll catch up with you later on at Arkley,’ she said. ‘See how they’re doing, OK?’

‘Right.’ He took a step backwards, half turned, on his way. ‘What do you make of Mullen?’

‘I think he needs to remember he’s not a copper any more.’

Thorne fastened the top button of his jacket and stuffed his hands into the pockets. Thinking about memory, perfect and fucked-up. Thinking that his memories of the time before he was a copper were getting pushed for space; shunted aside by less pleasant recollections. ‘You ever thought about getting out early?’ he asked.

‘Now and again. What about you?’

‘There’s times I think about it a fair bit.’

‘What sort of times?’ Porter asked.

‘When I’m awake…’

Tony Mullen reached into the fridge for the wine bottle, pulled the glass across the counter-top and poured himself a decent measure. He moved over to where his daughter was making herself a sandwich. Stroked the back of her head as he drank.

Neither had spoken since he’d come into the kitchen a few minutes before, and they continued to stand, each busy in their own way, sharing the space in silence until Juliet Mullen picked up her plate and walked out.

He listened to his daughter’s footsteps on the stairs, to the creak and click of her bedroom door, and to the music which escaped in the few seconds between those final two sounds. He strained to hear the murmur of Maggie’s voice, and, though he could hear nothing, he knew very well that in some room or other of the house his wife would be deep in conversation. She’d been keeping the landline clear for obvious reasons, but somewhere she’d be sitting or lying down with the mobile pressed to her ear; talking it out and talking it through to her family, her friends, anyone willing to listen and pretend they understood what was happening.

He’d spoken when he’d had to. He’d given the necessary information when it had been required of him, but aside from that, he’d said next to nothing. That had always been the way between them if ever there was trouble, if ever the family unit had been threatened in any way. He’d always be the one to go into himself, bottle things up; the one to turn the problem every which way without saying a word while others did the screaming and shouting. Luke was like that, too: never one to get hysterical. Maggie was usually the one that wore her heart on her sleeve and it was never easy to tell what was going on inside Juliet’s head.

It wasn’t very inclusive or touchy-feely, he knew that. It was old fashioned and out of step. He guessed that in some ways it might have been better if they’d all sat around and opened up, if they’d shared, but it wasn’t the way he or his family operated, and you couldn’t help the way you were.

He moved his fingers back and forth across the smooth, cold surface of the counter-top and thought about DI Tom Thorne. The cheeky bastard had given him a hard time the day before, badgered him, even though only one person in that room had made DCI, and only one was ever likely to. He was grateful to Jesmond for laying on the extra men, but Thorne was one he’d have to watch. That type of copper – the ‘bull in a china shop’ type – didn’t solve cases like this one. His son would be freed by doing what was simple and sound, and not by refusing to accept what you’d been told and banging on about how many names were on a fucking list.

Mullen emptied his glass and thought about the name he hadn’t written down. He told himself that it was unimportant; that it was acceptable within the scheme of things; that he’d done it for the right reason. A silly reason perhaps, but one worth the very smallest of lies.

He would have loved to forget the man to whom that name belonged, but it would never slip his mind. It was a name with unhappy connotations, after all. But it was a name – and this was all that really counted – that he knew damn well had nothing to do with his son’s disappearance. With who was holding Luke, or where, or what they wanted. So why did it matter, and what harm could come from leaving one name out of it?

He listened for a minute or two more, then moved back to the fridge.

What harm?

It was a bag. Just a plastic bag, that had done all the damage; was still doing it if assorted shrinks and social workers knew what they were talking about.

Probably one of those really cheap, stripy ones that you picked up at late-night supermarkets and shitty corner shops. The driver of the second car had never gone so far as to describe the bag in court, but that was how she always imagined it. Fluttering across the street and up on to the windscreen, held there by the wind, blinding the driver for that crucial second or two and causing him to swerve. A shapeless piece of jetsam that made him drive into the silver Mercedes coming the other way. That floated up like smoke at the impact, and sent her daddy through the glass.

Cheap and insubstantial. Virtually weightless. Something so terrible coming from nothing…

The boy was dosed-up now and out of it, and Conrad was getting a bit of sleep in the next room. It was the middle of the day, but both their body clocks had gone haywire. The curtains were closed all the time; it could have been morning, noon or night. It didn’t really matter one way or the other. It was boring, that was all. They just had to stay where they were for as long as the whole thing took; until they knew what was happening next.

When she dwelled on what had happened to her father, which was often, she never really thought about the other driver: unsighted and screaming behind the wheel; giving his evidence in a neck-brace; limping away down the steps outside the court while her mother shouted after him. She thought instead – and she knew how irrational it was – about the person who had sold the plastic bag. About the person who had filled it with fruit, or fish, or fuck-all worth talking about, and about all the hands the bag had passed through before it was finally tossed into the gutter. She thought about the people who would never know the part they had played in her father’s death. She imagined all their faces. She gave each one a life, and a family to fill it. And in her darkest moments, of which there were many, she’d take a member of that family away, and watch the life she’d made for someone fall apart.

She walked across to the portable CD player in the corner of the bedroom, turned the music up just a little to drown out the boy’s breathing. She took what she needed from her handbag and sat back down on the floor.

They’d argued again about the usual thing, Conrad doing that low, disappointed voice he saved up for the drug conversations. He told her that she needed to keep a clear head. She pointed out that it was precisely because the situation they were in was so stressful that she needed the lift. He got angrier then, reminded her that she always needed it, and she told him that the last thing she needed was for him to be so self-righteous, and that she’d sort herself out afterwards, when they had the money.
