Reilly, Ace of Spies is a 1983 television miniseries dramatising the life of Sidney Reilly, a Russian Jew who became one of the greatest spies ever to work for the British. Among his exploits, in the early 20th-century, were the infiltration of the German General Staff in 1917 and a near-overthrow of the Bolsheviks in 1918. His reputation with women was as legendary as his genius for espionage.
