I imagine that at this point, with no new stories appearing in the Observer for a few weeks, whatever lucky editor had responsibility for On Winter’s Hill is having to make decisions about whether to cancel it, to publish as is with a lengthy additional foreword by SW addressing the allegations, or to commission essentially a new book which addresses them, probably in conjunction with a walk travelogue and more of SW’s characteristic musings about the natural world.
The snag with either of the latter is that it involves SW playing ball and admitting some culpability. If she won’t, and it comes down to simply publishing OWH as it is or not, I imagine the decision would be based on whether they think that it would still turn a profit, ie. If there are enough diehard fans who will say ‘Oh, I heard there was some negative story, but I still like the books’.
And in this case, the publicity people would also have a dilemma. Not only would they have to recast the press releases, blurb material etc away from the ‘unflinching honesty’ take, they would also have to decide whether SW doing publicity (if she was prepared to) would actually have a negative effect on sales. And, whether, if she did do ‘normal’ publicity, she’d crack under accusing questions. Books do sell without an author doing publicity, obviously (Elena Ferrante etc), but would OWH? Would a single, high-profile ‘mistakes were made’ interview with a sympathetic interviewer be enough?
(ETA — I don’t know whether enough is generally known about the contents of OWH for it to be impossible to use the walk in it as the spine for SW musing about her ‘mistakes’? Ie would readers in general know perfectly well that these would have had to be retrofitted to a walk done before CH contacted SW?)
