On 6th October 1987, a newborn baby is found on the verge of a remote country lane in Suffolk. Police comb the area for clues and appeal for witnesses, but the mother is never found. The baby, Jess, is adopted. Journalist Lucy Greenwell has never forgotten the day when Jess was discovered. She was a child and lived nearby. For decades Lucy has wondered; what happened to Jess, and what could have driven a mother to leave her child in such an isolated place? When Lucy tracks Jess down, she finds a woman already deep in her own search for the truth, and a story far more tangled than either of them expected. What unfolds is a tale of long-held secrets and unintended consequences that spirals out of Jess's control.   Foundling is a six-part original series from Tortoise Investigates and The Observer

The Salt Path was the supposed bestseller debut book by Raynor Winn, selling millions worldwide. So when two more sequels came along with increasingly bold claims on reversing a terminal illness, why did the publisher Penguin not question it more?  Chloe also goes on the hunt for Raynor Winn's fourth  book…her true debut written years before The Salt Path.

Raynor Winn's memoir The Salt Path was a bestseller and literary phenomenon with millions of people captivated by this true story of financial ruin, terminal illness, and healing through nature. Raynor Winn has since published two more books and The Salt Path has been adapted for the big screen, starring Jason Isaacs and Gillian Anderson. At its heart it is a simple tale, of a couple embarking on a 630 mile trek in the face of stark adversity. When faced with nothing, they chose to walk. Then Chloe Hadjimatheou received a tip-off that the memoir may not be the "unflinchingly honest" account it claimed to be. And it led her to ask: how far can you bend the truth before it begins to break?
