I think she'd got away with so much over such a long period that she must have thought she was safe -- she'd stolen enormous sums of money from vulnerable people, repeatedly, and had bought Martin Hemmings' silence, avoided prosecution, managed to persuade both families not to go to the police about her thefts from TW's parents and her own mother by feigning madness, stonewalling, saying she'd stolen to save TW from depression and despair, and self-lacerating 'confessions' pretending remorse, and still managed to get family to house her afterwards for long periods.
I imagine that she thought that losing their house when the loan from 'James' was called in was (a) terribly unfair, because it's the only negative thing that actually happened to them as a result of years of large scale theft but (b) that as those particular chickens had come home to roost, that was the end of that and no one was going to talk about it, or link it to the appearance of a walking memoir by a 'Raynor Winn'.
And the slightly scary thing is that she was nearly right.
People from her family and the surviving Hemmings did recognise 'Raynor Winn' as Sally Walker, but no one did anything effective about it.
One family member phoned the general reception at PRH, but didn't make contact with anyone who wanted to listen or knew what she was talking about.
One phoned a couple of police stations, but without proof of a crime, and with the people who were her victims unwilling to go to the police or dead, no one was interested in pursuing it.
The Hemmings thought they might still be covered by the NDA.
Individually, Maxine Faramond was getting suspicious at the stream of bailiffs' letters and fines still arriving at Pen y Maes years after the Walkers' left.
Bill Cole, the Walkers' biggest fan, was beginning to smell a rat as his tenants repeatedly refused to make cider, and as TW told him he hadn't long left to live, SW published a book about his miracle cure.
But it wasn't until someone suspicious of TW's evident wellness and who knew their real names (still not identified?) got in touch with an investigative journalist with a nose for a story that any of this cohered, or that most of these people learned of one another's existence, and that the criminal past was put together with the fake illness, the fictional, self-exonerating 'origin story', and the largely fictional walk.
And I still think that if SW hadn't been greedy they might have got away with it all.
If she had been content with the success of the original book which made no firm claims about CBD, and/or had dialled back from the CBD diagnosis in TWS, saying it was clearly a misdiagnosis, and put a note in subsequent editions of TSP saying that the narrative reflected the belief they'd held at the time, and not continually told the media TW was dying, got involved in fake fundraising etc, then I think it's possible they might have got away with it and been able to live in comfortable obscurity on the proceeds, foreign rights, the film option and her various gigs with Gigspanner and teaching writing and a 'wellness' industry thing.
If they said TW was now not dying, hurrah, no one would have been suspicious of this healthy-looking man, and got in touch with a journalist. If they'd obeyed the terms of their lease and made cider, Bill Cole would have continued to be a big fan and defender. If they'd been cleverer about paying old debts, no one would have come after them. If SW had said 'I did stupid things that led to us losing our house' at the start of TSP, there would be much less of a story
So I suppose we should actually be grateful that they were greedy and stupid. That the health claims became more and more exaggerated, that the books kept coming, that they did things like unnecessarily alienating Bill Cole. Otherwise no one would have contacted CH. I'd still have not been able to get beyond a sense that there was something weird about TSP, and discovered when I googled 'Raynor Winn courtcase', nothing emerged at all, and that there was in fact no reference online to Raynor Winn before the publication of TSP.
