`The most formidable spy in history` - IAN FLEMING `His work was impeccable` - KIM PHILBY `The spy to end spies` - JOHN LE CARRÉ Born of a German father and a Russian mother, Richard Sorge moved in a world of shifting alliances and infinite possibility. In the years leading up to and during the Second World War, he became a fanatical communist - and the Soviet Union`s most formidable spy. Combining charm with ruthless manipulation, he infiltrated and influenced the highest echelons of German, Chinese and Japanese society. His intelligence proved pivotal to the Soviet counter-offensive in the Battle of Moscow, which in turn determined the outcome of the war itself. Drawing on a wealth of declassified Soviet archives, this is a major biography of one of the greatest spies who ever lived.
