Foundling | Tortoise Investigates

The Observer

Summary

Foundling is a captivating investigative podcast from Tortoise that takes listeners on a deep dive into the mysteries hidden behind public narratives. Rather than focusing on a single, linear story, the series acts as a home for high-stakes, long-form journalism that peels back the layers of human secrets, fractured identities, and the tension between personal memory and verifiable truth. The show is defined by its two distinct investigative arcs. One strand follows the poignant and heartbreaking mystery of Jess, a woman abandoned as a newborn in 1987, as she works with host Lucy Greenwell to uncover the identity of the mother who left her behind. This journey balances the emotional weight of trauma with the grit of a police procedural as they reconstruct the past. In parallel, reporter Chloe Hadjimatheou leads a rigorous investigation into the lives of Raynor and Moth Winn, the authors behind the blockbuster memoir The Salt Path. Here, the focus shifts to the intersection of literature and reality, questioning the accuracy of a globally celebrated story and the murky history of the people who wrote it. Whether exploring the origins of a lost child or the potential myths woven into a bestseller, Foundling excels at highlighting the complexities of the human experience. It is a show for those who love investigative storytelling that values persistence, sensitivity, and the pursuit of the truth, no matter how tangled the path to finding it might be.
