How far will two women go to survive a war? Having suffered a traumatic experience in the Blitz, Edie feels utterly disillusioned with life in wartime London. The chance to work with the Secret Operations Executive (SOE) helping the resistance in Paris offers a fresh start. Codenamed ‘Yvette’, she’s parachuted into France and met by the two other members of her SOE cell. Who can she trust? Back in London, Vera desperately needs to be made a UK citizen to erase the secrets of her past. Working at the foreign office in charge of agents presents an opportunity for blackmail. But when she loses contact with one agent in the field, codenamed Yvette, her loyalties are torn.
