Richard Sorge was dispatched to Tokyo in 1933 to serve the spymasters of Moscow. For eight years, he masqueraded as a Nazi journalist and burrowed deep into the German embassy, digging for the secrets of Hitler’s invasion of Russia and the Japanese plans for the East. In a nation obsessed with rooting out moles, he kept a high profile—boozing, womanizing, and operating entirely under his own name. But he policed his spy ring scrupulously, keeping such a firm grip that by the time the Japanese uncovered his infiltration, he had done irreversible damage to the cause of the Axis.

The first definitive account of one of the most remarkable espionage sagas of World War II, Target Tokyo is a tightly wound portrayal of a man who risked his life for his country, hiding in plain sight.
