Britain 's Special Intelligence Service, commonly called MI6, is not only the oldest and most storied foreign intelligence unit in the world-it is also the only one to open its archives to an outside researcher. The result, in this authorized history, is an unprecedented and revelatory look at an organization that essentially created, over the course of two world wars, the modern craft of spying. Examining innovations from invisible ink and industrial-scale cryptography to dramatic setbacks like the Nazi sting operations to bag British operatives, this groundbreaking history is as engrossing as any thriller-and much more revealing

For over 100 years, the agents of MI5 have defended Britain against enemy subversion. Their work has remained shrouded in secrecy—until now. This first-ever authorized account reveals the British Security Service as never before: its inner workings, its clandestine operations, its failures and its triumphs
