So, Finn is a drinker, and a serious one at that. How had he not noticed? They’ve been out for dinner, out to bars and clubs over the years and, sure, Finn had been drinking, but so had he. He hadn’t noticed his friend had been particularly the worse for wear. No more than him on some occasions, although that was hardly a recommendation. And the last time they went out, none of them had drunk much at all. He’d been driving and had one glass, Sophie and Finn sharing the rest of the bottle of wine.

But he knows alcoholics can be sneaky. His own sister was killed by a drunk driver, and that man claimed to be going to AA, while still downing bottles of Jack Daniel’s.

His phone rings, and he answers it. It’s Craig.

‘Bring my DC back now. He has work to do.’

Robin scowls, but he does as he’s told.

Robin squints at the tiny video screen. He’s annoyed he isn’t allowed inside, although he grudgingly understands why. Sitting behind the table in the interview room are Craig and DC Grey, and opposite them, Justin White, cameraman for the BBC.

They’ve already completed the first interview with the producer. A posh, officious man with nothing interesting to say. He hadn’t been near the van because it was too small, and only essential staff were meant to be there. Personally, Robin thought he hadn’t been present because he was scared of the storm, but it didn’t matter – he didn’t know anything. He maintained that the whole team had been on the best of terms in the run-up to the shoot, overplaying it so it sounded like the production of the BBC’s Storm Chasers was some sort of weather-obsessed Disneyland.

But Justin White is a different matter. He is constantly shifting his position in the chair, glancing around him.

‘You’re not under arrest,’ Craig is clarifying for the third time. ‘And as my colleague said, you are here on a voluntary basis and free to leave.’

‘But you’re recording me?’

‘Yes, and we’ll give you a copy of the video when you go. Now, can you tell us why you weren’t in the van?’

Justin White’s a good-looking man like Simon was, but rugged, while Dr Sharp was clean-cut. Long hair on top, tied back in a short ponytail, shaved underneath. Stubble. Checked lumberjack shirt and artfully ripped jeans.

He picks up the plastic cup of tea in front of him and takes a gulp.
