In this remarkable tale Nick Barratt delves into the shadows of the British and Soviet secret services to reveal the shocking story of his great uncle Ernest Holloway Oldham. After serving in the British army during the First World War, Oldham was drafted into the British Foreign Office. Over the course of the next decade Ernest was drawn ever deeper into the underworld of pre-Cold War espionage, towards a double-life that became the darkest of secrets. Enigmatic and gripping this is a journey through post-First World War Europe where agents, special agents and double agents lurked in the darkness, during a period of history when everyone had something to hide.
