They stop outside the multistorey car park, where Freya left her car earlier that afternoon, and she undoes her seat belt. Sitting in the cathedral grounds seems like a long time ago to Robin; so much has come to pass since then.

Freya opens the car door.

‘Sure you don’t want to come back to mine?’ she asks.

‘No, no. I’ll be fine.’ He forces a smile, and she gets out of his car. He doesn’t particularly want to be alone, but he also doesn’t want to inflict his company on Freya. She must have had enough of him over the past few days.

And as he drives to his house, he realises he hasn’t asked about her, or her case. Have those kids been charged with murder? He knows it was because of her unique slant that they’ve got that kid to confess. She is an incredible detective, and he never acknowledges that fact.

He gets home, parks up and lets himself into his house. The living room is still a state, denuded walls looking back at him accusingly. He will finish it himself, he decides anew. Even if it takes months.

He places his bag on the table and reaches inside, pulling out a memory stick. DC Grey gave it to him as he left the hospital.

‘It’s not relevant to the case,’ he said. ‘But I thought you’d want to see it.’

Robin had looked at it, confused, but before he could ask any more, Grey had been called away.

He makes a cup of tea now and fires up his laptop, putting the memory stick in the side. The computer loads a single video file, and Robin clicks it open.

The inside of the van comes into view. The timestamp in the corner reads 00:54; before the storm. Only Finn is in shot, sitting next to the table. Sharp is holding the camera close to his face; Finn looks embarrassed.

‘So, tell me about Sophie,’ Sharp asks.

‘What’s there to say?’ Finn replies, trying to push the camera away.

‘How did a nerdy old scientist like you get someone as lovely as her?’

Finn laughs. ‘No idea. But I’m a lucky man.’ He pauses. ‘I’m going to ask her to marry me.’

‘No!’ The camera shakes, as Simon leans forward and gives Finn a hug. ‘Good for you, mate.’

‘I’ve no idea if she’ll say yes.’

‘Course she will. So, tell me about her. How did you meet?’

Robin listens, mug of tea in hand, as Finn talks about Sophie, a shy smile on his face. It’s clear how much he loves her; Robin had no idea things were this serious between them.

‘Robin doesn’t like her, though,’ Finn finishes, and Robin feels the familiar flash of guilt.

‘Robin?’

‘My best mate,’ Finn replies. ‘And I can’t blame him. Both Sophie and I behaved like wankers when we saw him last.’
