During the 1940s, a playboy spy became one of wartime’s most successful double agents, as well as the reported inspiration behind James Bond.

A gambler and womanizer who spoke several languages, Dusko Popov was approached by a friend working for the Abwehr, Germany’s military intelligence.

But Dusko was vehemently anti-Nazi. He went straight to the British and volunteered his services, adopting the codename 'Agent Tricycle'. Intelligence officers then created realistic - but false - information for Dusko to pass back to his Nazi spymaster.

And it was during this time, that Dusko’s path crossed with a British naval intelligence officer called Ian Fleming, later the creator of James Bond.
