‘There was no love lost between Finn and Jacob. Jake was one of the popular kids, even though he was a few years younger than Finn, and he made Finn’s life a misery at that camp.’

Robin frowns. ‘He did?’

‘Yeah, without you there, Finn was fair game. He was always a target for bullies, but they didn’t dare if you were around. I know you punched a few for him over the years,’ she says, with a smile. ‘Finn and Jake got in a fight the day before, and Finn said he wished him dead. So, when Jake died…’

‘He couldn’t possibly have thought it was his fault?’

‘No, but he took it badly. You know Finn. Delicate soul. He didn’t like the thought that Jake had died and he couldn’t make amends. He did nothing but cry for weeks, wouldn’t eat, didn’t go out. Didn’t want to go to the funeral. He missed the start of school, do you remember?’

Robin nods. ‘You said he had glandular fever.’

‘It was as good an explanation as any. I took him to a counsellor, but it didn’t make any difference. And then you started writing him these silly notes, putting them through the door because you said he was infectious. It made him laugh. And your cast came off, and you wanted to play football and wouldn’t take no for an answer.’

‘I was a selfish dick, even then,’ Robin replies, ruefully.

‘No, it was good for him. It got him out of the house. There was you, with your limp after your broken leg. And him, all pale and skinny. You made quite a pair.’

‘And that’s it?’ Robin asks. ‘That’s all there was to it?’

Josie nods. ‘I thought that if DI Craig knew Finn had depression in his past, it would be one more black mark against his name. I should have told you. It was ridiculous.’

‘It’s fine. I should have left it be. I’m sorry,’ Robin apologises.

Josie nods, then her mouth turns down and she looks like she’s going to cry again. ‘What are we going to do, Robin?’ she says.

Robin sighs. ‘Exactly what the doctor said. Get him settled in this therapy unit. Make sure he sees the right people. And you never know what might happen.’

The two of them walk slowly back to Finn’s room, arm in arm. When they get there, Sophie’s by Finn’s bedside, talking quietly to him. They both look up when Josie and Robin arrive.

‘Rob!’ Finn says, all smiles. ‘Haven’t seen you in ages.’

Robin returns the grin. ‘I know, Finn. It’s been too long. Listen, I’ve got to head off. Work is calling. Sophie,’ he says, ‘can I have a word?’

Sophie looks surprised and gets up. They walk out into the corridor.

‘Have you spoken to the doctor?’ Robin asks.
