About the medical letters:
I think most of us regret that medical letters apparently needed to be shared by the Winn/Walkers when they are in normal circumstances very private things. In these particular circumstances however a central focus of the books is Moth/Tim's health and Raynor/Sally - and presumably Moth/Tim - chose to publicly share that and to keep on sharing it.
And not just to share it with readers of 3 books but also of magazines and newspapers, watchers of podcasts and TV, audience members at gigs and book events, and with filmgoers. Their story centring on Moth/Tim's health was not going quietly after the film release. In the offing were residential non-fiction writing courses at Arvon, another tour with Gigspanner including the existing album and journal, a fourth book and a new project of some sort of wellness retreats. It has not just been shared for a number of years, it has been successfully monetarised.
So when the nature and severity of Moth/Tim's health issues are questioned - not by idle or cruel gossip but by a respected investigative journalist and newspaper, a number of medical specialists and the apparent initial whistle-blower - this will naturally be of interest and doubts will be raised, particularly for those who had felt invested in their story. It is not only the questions about Moth/Tim's health which are causing these doubts, it is the combination of those with other compelling questions: about the real reason for the loss of the house, the ownership of land and a renovation project in France, Raynor/Sally's theft of over £60,000 (over £100,000 in today's money) from her employer, money owed to others and inaccuracies in the descriptions and timings of the walks (all alleged). All those questions and doubts form a powerful combination. Jason Isaac's heartfelt outburst of 'they were conned!' on BBC1's The One Show seems out of kilter.
As part of Raynor/Sally's statement it was decided to release the medical letters in order to refute the doubts about Moth/Tim's health. She has stated in the books and in interviews that he had been given a clear diagnosis of CBD, that this happened when they lost the house and before they set off to walk the path, that this was terminal, that she expected to lose him in two years and that he was experiencing a raft of both acute and chronic symptoms. I can not see verification of all that in the letters posted. Like many other people, I also genuinely wish Moth/Tim well, whatever the truth is..
I think the medical letters were intended as a mike-drop moment but are instead a bit of a smoking gun. It seems to me that they have shot themselves in the foot with this and other aspects of the statement.
