Twenty-five years after the end of the World War II, ageing British Special Operations Executive Noah Ainsworth is reflecting on the secret agent who saved his life when a mission went wrong during his perilous, exhilarating years in occupied France. He never knew her real name, nor whether she survived the war. Inspired by her father's wartime exploits, Noah's daughter Charlotte begins a search for answers. What follows is the story of Fleur and Chloe, two otherwise ordinary women who in 1943 are called up by the SOE for deployment in France. Taking enormous risks with very little information or resources, the women have no idea they're at the mercy of a double agent within their ranks who's causing chaos. As Charlotte's search for answers continues, new suspicions are raised about the identity of the double agent, with unsettling clues pointing to her father.

In this episode Gregory Dobbs chats to Kelly Rimmer about the real women that inspired her characters, the secrecy surrounding the Special Operations Executives even after the war had ended, and her passion for exploring the secret lives of real people through historical fiction.
