‘Nobody deserves to die, of course,’ he says on a long exhale, ‘but in Rhiannon’s mind, sex offenders and paedophiles were fair game.’

‘Was she raped herself?’ asks Bryan, escalating the chat with admirable aplomb. ‘Was that why she held sex offenders in such particular disdain?’

‘If she was, she never mentioned it in the diaries,’ replies Freddie. ‘It could explain a lot but I have no evidence to suggest that, no.’

‘What about the grandfather?’ calls out an achingly thin woman with red hair three rows from the back. ‘The one she watched die in the river?’

Freddie looks in the woman’s general direction. ‘That can’t be proven, madam. She certainly didn’t divulge such information to me.’

‘What kind of vibe did she give off?’ asks Bryan. ‘Were you scared in her company?’

‘I didn’t know what Rhiannon had done when I met her. I thought she was simply Craig Wilkins’ girlfriend and he was on remand for multiple murder. I thought she was a victim. I felt sorry for her but no, I wasn’t scared of her.’

Bryan’s practically rubbing his crotch by this point. ‘What was it like when you got that mail with her diaries in?’

‘It was an ordinary morning, a few days into the New Year. My husband had gone off to work. I was taking our kids swimming and the postman rang the door. I had a parcel and I left it on the dining table.’

‘You didn’t open it up right away?’

‘No, I assumed it was some books I’d ordered for my husband for his birthday. They were coming from Australia.’

‘Right, right.’

Two mentions now of the husband but the Frow don’t seem to have noticed. One brunette is visibly unbuttoning her blouse.

‘When I got back, I made the kids lunch and we settled down to watch a film – Coco, I think it was. I put the parcel in the wardrobe and forgot it.’

Cue audible gasp.

‘I know, it’s crazy, isn’t it? But my husband’s birthday wasn’t till February so I thought I’d wrap it up nearer the time. About two weeks later, the parcel fell out of the wardrobe while I was packing away some blankets and I opened it to have a look at the books. Instead it was these two handwritten diaries. On the front it said “The True Confessions of Rhiannon Lewis, aged 27/28”.’

Another audible gasp.

‘And it began on New Year’s Eve 2017 with her realising her boyfriend Craig was having an affair. It went on to talk about her life in minute detail, and included the murders of various people. Planning it, doing it, covering it up. I couldn’t believe what I was reading.’

‘Wow, that’s completely amazing.’
