A huge figure in the history of British espionage and one of the models for James Bond, Sidney Reilly was born in Russia in 1873. To his employers, the British Secret Service, his background was a mystery yet his immense charisma took him into the epicentre of British establishment. Reilly lived for danger, he spoke seven languages and was rumoured to possess eleven passports and a wife to go with each.

Among his exploits in the early twentieth century were the infiltration of the German General Staff in 1917 and the near overthrow of the Bolsheviks in 1918. His reputation with women was a legendary as his genius for espionage. Reilly: Ace of Spies was adapted into a BAFTA-winning television series in 1983, starring Sam Neill as Reilly and Ian Charleson as RH Bruce Lockhart.
