I think as rapidly as my aching head will allow. ‘Copper Beech,’ I say, after a moment. ‘Felix was siphoning off funds. And you knew about it? Of course you did: Felix never did anything without you. Except you wouldn’t be able to access the money,’ I add slowly, working it through. ‘Not if they thought Felix had absconded with it. They’d be watching you too closely. But if he was dead, that’d be a different matter. If he was dead, and someone else was arrested for his murder, no one would be looking at either of you. You’d just have to wait for the fuss to die down, and you could disappear and start again. By the time anyone figured it out, you’d be long gone.’

‘This is why I like you,’ Stacey says admiringly. ‘You get it. Going after the pension funds was Felix’s idea. His plan was to leave the country and have me follow him later, but it’s not that easy to slip abroad these days, not with all the facial recognition software out there. Do you know how hard it is to avoid cameras these days? We needed the police to think he was dead, and one single image on CCTV at an airport or train station would have sunk that idea, so Felix came up with the plan to hide down here until things blew over.’

The police aren’t stupid: they’d have been watching Stacey either way. But she and Felix created a false narrative of marital problems that threw all of us off the scent, and I played my part for her perfectly. Who’d suspect them of collaborating in a scam together when they were living apart and consulting divorce lawyers? The physical abuse on both sides: perhaps that was all part of it, too.

Although, I think, casting a glance at Felix’s motionless form on the bed beside me, perhaps not.

‘So what happened?’ I ask, indicating Felix. ‘He can’t have planned for this.’

‘He was never supposed to be down here this long,’ she says. ‘We only meant for him to be here a week or two at most, and then, once everyone stopped looking for him, he was going to slip quietly out of the country. I’d join him later. There’s no future for me here. They want to move me to morning television.’ Her expression darkens. ‘But then Harper stirred everything up with that ridiculous campaign of hers to find him. There was too much attention: from the press, from the police, from that ridiculous Kyper Nation of hers. Felix got impatient. He wanted to call the whole thing off. We … disagreed.’

I can’t hear him breathing. He hasn’t moved once in the entire time Stacey’s been talking.
