He kicks his shoes off and lies on the bed, staring at the ceiling. They haven’t achieved much today; just uncovered more questions and worry. Why was Finn talking about this boy? It was an accident. A horrible one, especially if Finn had been there, but they’d found nothing that linked it to Sharp.

Next to him, his phone rings. It’s a number he doesn’t know and he hesitates before he answers it.

‘Robin? It’s Sophie. Sophie Hall.’

Her voice is high-pitched and breathless. Robin inwardly sighs.

‘Hi, Sophie,’ he says wearily.

‘Josie gave me your number. I need to talk to you. I was interviewed by Detective Craig today.’

‘And how did that go?’ Robin hopes she didn’t show up stoned, although from the frantic tone he guesses she could do with some weed right now.

‘Fine. I mean, I didn’t say anything. But they think Finn did it, Robin. They think he killed Simon.’

Robin frowns. This is hardly news. ‘They wouldn’t have arrested him if they didn’t think that, Sophie. How is Finn?’

‘Same. No change.’ He hears sniffling at the end of the line and feels sympathy for the girl. This is the man she loves, after all. He should be a bit kinder to her. ‘It’s just… they mentioned there’s some camera footage from inside the van, but they can’t find it.’

‘I heard that, too.’

‘But… but shouldn’t they be trying a bit harder to track it down?’ Her voice is getting hysterical again. ‘Isn’t that their job? To find every bit of evidence?’

‘I’m sure that’s—’

‘Can you make sure they are? Phone them, shout at them or something?’

‘For a start, my involvement in the investigation is only as an observer. Any evidence recovered by me would be inadmissible in court. Secondly, Craig is a higher rank than me…’

‘So?’

‘So, she’s in charge. That’s how it works.’ Robin pauses, and he hears her crying again. ‘I’ll call her,’ he says, resigned to his fate. ‘See what I can do.’

Sophie hangs up, and he collapses back on the bed with a sigh. Like he can influence Craig. But he’ll do as he said, and put another call in. Perhaps he could phone DC Grey. The boy seems far easier to bully.

He glances at the clock. It’ll have to wait: he needs to have a shower and change. And he has to admit, he’s looking forward to seeing Sandra. Catching up properly for the first time in twenty-two years.
