‘Oh God, you’re right.’ Sara could hear his voice in her head, telling her about it. ‘I’m pretty sure he mentioned the Cloud.’ She looked again at the ruined office. ‘He’s just made sure there’s no physical evidence, hasn’t he? Nothing that can link him directly with the site. But it’s still there somewhere.’ She sighed, despondent. ‘When he was employed, he worked on a government project to track down criminal sites on the dark web, so he knows all their software tools and how to avoid them. We’ve got to find him and make him destroy it, because I’m not sure anyone else is going to be able to. Not quickly, anyway.’

‘Yeah, and how are we going to do that?’ Hailey threw up her hands, frustrated. ‘We don’t know where he’s gone, or if he’s planning on coming back. And even if he said he’d destroyed it, I wouldn’t believe him.’

Sara wiped her hands over her face, wincing when she touched the tender spot where Matt had punched her. ‘Bloody hell, Hailey. I can’t believe he’s the same man I married.’ She leant against the wall as an unwelcome thought popped into her head, another blow to her battered self-respect.

‘I’m just wondering about the Matt and Fiona situation.’ She looked up at the fluffy clouds drifting across the sky before focusing on her sister again. ‘I know we’re sort of friends, but she keeps her cards close to her chest. Doesn’t give out much information about what she’s up to, while she just hoovers up all the details of what’s going on in everyone else’s life. In fact, she makes it her business to know. And she does love it when you owe her a favour. It’s like…’ She stopped talking, a sudden moment of clarity illuminating her thoughts like a searchlight. ‘Oh my God, that’s it.’

Hailey scowled at her. ‘What’s it? What are you talking about?’

‘Something James said earlier. I haven’t told you, have I? He was so scared when he saw me, basically had me chased out of the ward, but not before he’d let slip that the person behind this scheme persuaded him to take me with him on the weekend because it would be doing them a favour.’ She nodded, sure she’d got it right. ‘He was scared to be seen talking to me. Which makes me think he was warned off. Whatever happened to him in the quarry, I don’t think it was an accident.’

‘Christ, Sara.’ Hailey ran a hand through her hair, frowning. ‘What have we got ourselves into?’
