I did wonder that, but thought it might have fallen under the heading of what CH talked about on the AMA as the Walkers’ right to some privacy — that when something she’d discovered didn’t add significantly to what she considered the public interest angle of the story, she left it out. Sign of an ethical journalist.
If I’m remembering rightly from the podcast, those handwritten letters were from SW to her mother after the theft had been found out, and her mother, after a period of estrangement, had allowed her get back in touch by letter. So it’s possible that they cover much the same territory as the ‘confession email’, but are more personal (and painful?) because they’re to the actual victim of the theft?
Or that ‘Anne’ or another relative of SW asked CH not to quote them because they felt they contravened SW’s mother’s privacy or that she’d have hated them being on a podcast? Maybe the older woman whose ‘podcast name’ I’ve forgotten, but who called SW’s mother ‘Auntie’?
Or that their primary importance, in being handed to ‘Anne’ on her mother’s deathbed, along with the email confession, was really as a means of authenticating the email, as from the same source?
That reminds me of another thing from the AMA. That CH had got her copy of Lightly Salted Blackberries from someone to whom SW had sent it because they were mentioned in it. She didn’t want to say more because she hadn’t asked permission.
That’s interesting (1) because it’s part of the normal publication process for memoir (publishers will encourage you to send a copy of the MS to anyone identifiable and mentioned, to check if they’re ok with their portrayal, and to stave off anyone insisting on inaccuracies being expensively altered in subsequent editions, or taking legal action), and also (2) to think about who SW could/would have sent LSB to?
So many of the Walkers’ encounters are either fictional or unidentifiable chance-met people they had no way of contacting (if they even existed), and so many people whom she represents in a hostile way. I mean, imagine ‘Anne’ being sent a copy of LSB and being asked if she’s ok with her portrayal as ‘Polly’!
ETA I’m not suggesting we try to identify who it was, but it’s actually surely a very small pool of people who are not represented with hostility or inaccurately, and for whom SW had contact details to send the LSB MS to?
