Chris gave voice to her thoughts. ‘Thing is though, Bill, the shot that killed Russell Fox was a clean one. SOCO didn’t find any other stray bullets and the pathologist reckons he died instantly. And a gun like that, well, it’s a lot of trouble to go to for a prison spat.’

Clare nodded. ‘Yeah, it’s a good point. Do we know anything about Zac’s previous? I know he did time for an assault but was there anything firearms-related?’

Bill shook his head. ‘Sorry, boss. No idea. I can look, though.’

‘We’re looking for a marksman,’ Chris said. ‘But it could be Zac supplied the weapon.’

‘I think we’ll bring him in,’ Clare said. ‘Chris, can you get onto the cops in Leven please? See if they know where he is.’

‘Way ahead of you,’ Bill said. ‘I’ve got an address for him. And there’s another thing…’

‘Go on.’

‘Sara said something about a car being nicked at the weekend.’

Clare’s brow furrowed.

‘I remember that,’ Chris said. ‘You were away at your posh wedding. A BMW X5, wasn’t it?’

‘Yeah, that’s it,’ Bill said. ‘Nice car. No sign of it so far but word is Zac’s stealing vehicles to order.’

‘Bit of a stretch, Bill. Lots of cars go missing.’

‘But they don’t all pick up a speeding ticket in Leven.’

Clare looked at him. ‘You’re joking?’

He grinned. ‘Nope. Largo Road in Leven. Early hours of Saturday morning.’

‘The same one stolen from St Andrews?’

‘Yup.’

Clare shook her head. ‘I don’t get it, Bill. Surely a seasoned thief like Zac would be watching out for speed cameras?’

Bill shrugged. ‘Maybe. But chances are a car like that’s heading abroad. By the time the ticket arrives at the registered keeper’s address it’ll be long gone.’

‘Shipping container?’ Chris asked.

‘Either that or broken down for parts then shipped. Easier to manage like that.’

Clare frowned. ‘But surely these cars have trackers?’

‘They do,’ Bill said. ‘But the thieves use jamming devices. And you know what policing priorities are these days. Car theft’s way down the list.’

‘Insurance companies cough up, so problem solved,’ Chris added.

Clare shook her head. ‘Not right, though, is it?’

‘No argument there, boss,’ Bill said. ‘Want a copy of the speeding photo?’

‘Please. Then get on to Leven and tell them to bring him in.’

‘That phone number Samantha Reynolds gave us,’ Chris said, as Clare was packing up for the night.

She looked up. ‘Yeah?’

‘No luck. Burner phone. No way of tracing it.’

Clare sighed. ‘No real surprise there. Any word on Val Docherty’s whereabouts?’

‘Still in Edinburgh.’

Clare’s brow furrowed. ‘Was it Barnton?’
