He picks it up and tips the contents into his palm. His stomach drops. It’s a black memory stick. He’s seen one like this before. He turns slowly, holding it between two fingers.

‘Take it,’ Liv says.

‘What’s on it?’ But he knows. Of course he knows.

Amy had one just like it. With footage from the CCTV of the garage. Footage proving he met with Trevor Stevens mere minutes before he had his fatal car crash.

‘Amy gave it to me,’ Liv confirms. ‘The night she died.’

Lucas has finished feeding and she holds the drowsy baby in one arm, while re-dressing herself with the other. It’s such a surreal conversation to have in these circumstances. Death, murder – and newborn babies.

‘And what have you done with it?’ Robin asks quietly.

‘Nothing,’ Liv replies. She winds Lucas, then deftly swaddles him in a blanket and places him in the carrycot on the floor, before sitting carefully back down on the sofa. ‘And I don’t intend to. This is Amy’s shit, not mine. Having it in my house feels dirty. I don’t want it any more.’

Robin carefully puts it in his pocket. ‘There’s no other copy?’

‘Not as far as I know.’

‘Thank you, Liv.’

But Liv shakes her head. ‘Robin, I don’t know what you did, or what went on between you and Trevor, and I don’t want to know. You and I have spent a bit of time together over the last year or so, and I pride myself on having a good sense about people. And I think you’re one of the good ones.’ Robin shakes his head, but stays quiet. ‘You did the right thing for Jonathan. And you did the right thing for me. That’s all the evidence I need. Okay?’

Robin nods slowly. ‘Okay.’

Liv smiles. ‘Now make me a cup of tea, will you? I’m gasping.’

It’s late by the time Robin leaves. The sky is getting dark, night closing in. He’s stayed with Liv far longer than he intended, taking brief childcare duties while she had a shower (although Lucas slept the whole time, so Robin didn’t have to do anything), then tidying up the mess in her kitchen.

They talked, a bit. Liv mainly gushing about her baby, Robin about the twins. It felt good. Therapeutic even, to see her doing so well.
