I don’t know about wellness retreats. The ‘Raynor Winn’ brand is pretty tarnished, so while I suppose it’s possible they could do it by themselves in a house they owned, I’m not sure anyone with a suitable venue for hire or an interest in investing in a wellness business is going to be crazy about being associated with a known conwoman and thief.
I don’t know how well Bill Cole is known in Cornwall generally, but I’d assume local people will be aware of the Walkers’ moonlight flit from Haye Farm, and other people with minor collateral damage like the Treen and St Ives’ campsites and the cafe with the (imaginary) sweary, unpleasant owner and Ruth Saberton, and the young couple who did the actual cider making at Haye, all of whom would know the Walkers as business poison.
And, if they did do wellness stuff entirely by themselves, unless it’s so lowkey it’s almost not there, they’d be pumping money into something for a very uncertain return. They’ve only got SW’s royalties now, as far as we know, unless they made some v savvy investments, they’re paying rent, and OWH is looking doubtful. Gigspanner aren’t going to have her back, and I’d be surprised if Arvon or any other opportunity for teaching writing would touch her with a barge pole now.
And even aside from the money stuff, would SW really risk someone asking awkward questions about theft and neurological conditions during a breath work session or a seaweed bath?
