OK, an update. In order to verify what I found earlier, I've spent a lot of tonight tediously scrolling through someone's Facebook page which took AGES because they've posted almost daily for the past few years and I needed to go back over a decade. (Plus we have a new kitten that kept trying to swipe my phone!).
Anyway, I got there and the info checks out. I needed to be sure it wasn't a typo in the original thing I found. I think it's pretty big, and it may already be on CH's radar given what she hinted at in the news event. So I'm going to email CH in the morning.
Sorry for the secrecy but with my journalist hat on, I think this info has potential for the basis of a story. To my mind, it certainly seems on a par, if not bigger, than the Bill Cole piece. What I will say is it seems to blow a big hole in the idea of the the walk in 2013 being continuous. Just to be clear, I'm not saying they didn't walk any of the SWCP. What I am saying is the continuous walk, as depicted in TSP (from setting off in Minehead to when Raymoth stop and head Polly's for winter) doesn't align with this new info. It's not a case of quick break either, its a huge gap that throws up a big question mark over when they walked. In doing so, it could undermine the idea of the walk as a journey of redemption narrative, which would not be "unflinchingly honest."
The book's story hangs on 3 crucial pillars: victims of homelessness, Moth's illness, and the walk. We've all seen the first two crumbling before us. I think the final one, without an extraordinary explanation, is about to go the same way.
