‘We could talk to them. But what we have is a lot of surmise and maybe some circumstantial evidence. I am not sure how seriously they would take us – especially when they hear who we are accusing. How does it sound to you: “The most powerful media baron on planet Earth murdered my sister and then tried to bump me off too”? They’re going to think my grief has driven me mad. Remember that’s what I thought – and I’m me!’

‘We’ve got motive. We’ve got the beginnings of a paper trail.’

‘Do we really have that? Let’s take stock. First, that dynamite briefing from Rep was so off the record that if the police approach him he’ll deny all knowledge of me. Jeremy will never co-operate with an enquiry because he’s worried his mum will find out he’s gay. The Polish security contractor has vanished – and to all intents and purposes never existed. And the one bit of incriminating evidence we have is something we stole while breaking and entering into a private house. If we go to the police now, the most likely outcome is that we’ll be charged with burglary and that will be that.’

There is an old lady four seats away on Jess’s side of the train who gives me a funny look and I realise I have been talking too loudly. Lowering my voice, I say, ‘We can’t go to the police, or write anything, until we have demonstrable evidence of the hole in the pension fund and that it was Breitner who paid off Deyna.’

Jess has stopped clicking the pen and is giving me a sceptical look. ‘We’re going to struggle to obtain any of that.’

‘No one said this job was easy. But I do have a sort of plan.’ I explain about the safe in the Globe’s newsroom. ‘I have to get inside it.’

‘That’s not the craziest idea you’ve ever had,’ she says. ‘But it’s close. And how exactly does it actually help us prove anything?’

‘There will be a record of someone removing a large sum of money around the time that Clare was killed. I need to see who took the cash.’

‘I get that. But how on earth are you going to get into the safe?’

‘Our friend Kevin’s going to open it for me.’

‘Kevin Wilkinson? Why would he do that?’

‘Because he thinks I’m working with him on a story he’s desperate to publish.’

‘Namely?’

‘Namely that Kendall is rogering Jeremy.’

‘You’re going to hang that poor boy out to dry?’

‘Nah. Probably not. But there’s no harm in Kevin thinking I am.’

Out of instinct, I pull out my phone. No signal down here, but we’ll be back at street level soon.

‘No need to call Kevin.’

‘Why not?’

‘I’ve got a better idea.’
