This book investigates the role played by William Donovan, the OSS mission in London and the Carpetbaggers, the US Squadron which was sent to RAF Tempsford to be trained by the 'Moon Squadrons' before undertaking their own missions from Harrington. Not only does it describe the work of pilots and crew members, it also details some of the missions and gives insight into their social life. It includes the story of Owen Johnson and Elizabeth Devereaux Rochester, the first American agents to be parachuted into France, and Juup Kappius, Hilde Meisel and Ann Bayer, the first OSS agents to be sent into Germany before the invasion.
