‘Please tell me you have something,’ she said.

‘We spoke to Russ Beacham’s mother again and she said that he took his grandparents car a while ago and hasn’t returned it,’ Adrian explained.

‘So, we need to look for this car then. What is it?’ Gary asked.

‘Nothing too fancy, just a silver Ford Focus,’ Adrian said.

‘Oh good, there aren’t many of those around,’ Gary rolled his eyes.

‘It is what it is,’ Adrian shrugged.

‘Do we have any possible ideas about where it might be?’ DCI Kapoor asked.

‘Well, the mother said the last time he’d taken it with Caitlin they drove out to Kennick in it, so I guess anywhere around there might be a good starting place, plus the surrounding area too,’ Adrian said.

‘By surrounding area do you mean Dartmoor? Roughly a thousand square kilometres of land? Brilliant,’ Gary said.

‘Can I get you a coffee or something? You seem unusually irritable,’ Imogen acknowledged.

‘Am I not allowed an off day?’ Gary asked.

Adrian leaned against the wall and folded his arms; he hadn’t dealt with bad mood Gary before, but he imagined it worked a lot like bad mood Imogen, who he had much experience with. If Gary was going to share what was bothering him, he needed the space to do it in. Badgering people for information only ever worked when you had them in an interrogation suite and even then, it wasn’t a given.

Gary opened his laptop and started tapping away. He pulled up several videos on the screens and pressed play on one of them.

‘I’ve got something, too,’ Gary said as the video started playing.

‘What’s this?’ DCI Kapoor asked.

It was Hugh Norris’s office and after a few moments it became apparent that it was the murder. The resolution wasn’t great and it wasn’t from a particularly helpful angle.

‘What do you think it is?’ Gary said, looking at Adrian.

Adrian watched as the murder unfolded in front of him. The killer was wearing a hoodie and his face was covered, so there was no way of telling who it was, but still, this was a great piece of evidence, if only to understand the logistics of the crime.

‘Where did you get this?’ Adrian asked.

‘Gillian Mitchell’s computer. The crime techs didn’t mention there being any hidden cameras in the offices, but there must have been and Gillian had the videos encrypted and hidden inside a ridiculous amount of subfolders – it took me a while to find it. I’ve passed this information on and Karen Bell went to check for the camera. Unfortunately, whoever the cameras belonged to has had them removed. Someone with access. There is more footage though. Most of it’s pretty dull – just a bloke in his office. Still got a fair amount to get through, but I thought you would want to see these.’

Gary pulled up the murders of both Robert Coley and Gillian Mitchell in split windows. Same figure, same coldness.
