When I first call Ros Hemmings, I expect her to be surprised. A widow in her 60s living in rural North Wales, she has never received a call from an investigative journalist in London. But instead she tells me: “Oh no, I have a very good idea why you are ringing.” She has been waiting for this call for years.
Hemmings rightly suspected that I wanted to ask her about a woman she knows as Sally Walker. Millions of people around the world know Sally by a different name: Raynor Winn. She is the author and protagonist of one of the most successful British non-fiction books in recent years. The Salt Path traces Raynor and her husband Moth’s 630-mile journey along the sea-swept South West Coast Path.
