IF LIFE is a spin on fortune’s wheel, Raynor Winn always seems to lose. In her bestselling 2018 memoir “The Salt Path”, Ms Winn recounts a journey she and her husband, Moth—recently homeless and reeling from his diagnosis with a terminal illness—made around Britain’s rugged south-west coastline. In May her “unflinchingly honest, inspiring and life-affirming true story” became a box-office hit, starring Gillian Anderson and Jason Isaacs. And then some pesky journalists pointed out that many details, big and small, seem to have been invented or exaggerated. Alas, poor Ms Winn has since had “vitriol poured on me from all quarters”.
