'An important piece of intelligence history, hitherto neglected or perhaps deliberately buried'
Sir Richard Dearlove, Chief of MI6 1999-2004
'A highly informative read on the work of intelligence and the exercise of political judgement at a key and tragic moment in history'
Sir John Scarlett, Chief of MI6 2004-9

The forgotten tale of MI6’s top spy in Nazi Germany and his bid to stop the Second World War.

In the world of espionage, where the accounts of renowned spies often dominate the narrative, this is a rare gem – an untold story of a completely unknown spy. Baron William de Ropp, a Baltic German aristocrat, wasn’t just any ordinary spy; he was MI6’s top secret agent in Nazi Germany from 1931 to 1939, managing to escape Berlin just before war broke out. This unsung hero had direct access to Adolf Hitler and an inside track on the Nazi regime. His reports, shrouded in secrecy, had the power to shape British policy toward Germany in a pivotal period of history.

The Spy and the Devil is a riveting tale of espionage, intrigue, and the untold impact of one man’s secret mission on the course of history. A journey into the shadows of Nazi Germany, where a forgotten British spy worked tirelessly to avert catastrophe, and discover the secrets that history almost left behind.

Bill de Ropp’s story has never been published in full before, adding an extra dimension to what is, by any standard, the account of a very remarkable man. Drawing on his years of service in the Foreign Office, Tim Willasey-Wilsey offers an insider’s view of this outstandingly effective but enigmatic British spy.
