Sally turned towards West. ‘Have they brought Kelly’s wife in yet?’

‘She’s waiting for us in Interview Room 2.’

She nodded. ‘Good. If we’re going to nail this one, we need to make sure we tie up all of the loose ends.’

Her phone rang and she glanced down at the display. It was David. She hadn’t really got time for this but she’d better take it – she’d been a bit rough on him the last time they spoke.

‘Hello.’ She held her hand up to West, who was hovering by the door, and said, ‘You go through, Tom. I’ll join you in a moment.’

She could hear David on the phone, saying, ‘Sal, is that you?’

‘Hi, David, sorry about that. Just had to sort something out.’

His voice sounded strained – anxious. ‘Sal, there’s something you need to know.’

‘Calm down, David. What on earth’s wrong?’

‘It’s Fuller.’

‘Who?’

‘Neil Fuller, the guy who worked as Beth Kinsella’s assistant at Bailsgrove. The guy who we took on as our site assistant. I’ve just been to see Beth’s father. He gave me a tape – a video tape.’ His breathing was ragged. She could barely make out what he was saying.

‘Slow down, David. What are you on about? None of this is making any sense.’

‘I don’t have time to explain. Just listen to me, Sal. I’ve found a tape that Beth Kinsella made. It shows Neil Fuller taking backhanders from Paul Marshall – the developer who owns the site. Fuller who worked for Beth and alongside Jack Tyler. Do you understand, Sal?’

Sally was focused now, fully concentrated on the job in hand and what it meant for her investigation. ‘Right, where are you, David?’

‘I’m in Derbyshire.’

Damn. She was hoping he’d say he was at Bailsgrove. ‘You need to contact site, warn Clare and Jo and the others. Whatever they do, tell them under no circumstances should they approach Fuller.’

‘I’ve already phoned Jo. She said Fuller didn’t turn up for work this morning, and he didn’t ring in either. Clare’s gone down to his house in Gloucester to try to find out what’s wrong with him.’

‘Look, David, I’ve got to go. I’ll ring Mark Stone and get his boys onto it.’

Her brain whirring away at double speed now, Sally abandoned all idea of interviewing Damian Kelly’s wife. Whether Kelly’s wife would provide him with an alibi or not was hardly relevant if there was every chance that Fuller, not Kelly, had killed Jack Tyler, and very possibly Beth Kinsella too. The one thing that Kelly had lacked was a solid motive. But it was all too obvious that Neil Fuller may have had one.
