The incredible story of the greatest female spy in history, from one of Britain’s most acclaimed historians, Ben Macintyre.
In a quiet English village in 1942, a devoted wife and mother-of-three known to her neighbours as Mrs Burton seemed to epitomize rural British domesticity. Far from a British housewife however, ‘Mrs Burton’ – born Ursula Kuczynski, and codenamed ‘Sonya’ – was a German Jew, a dedicated communist, a colonel in Russia’s Red Army and a highly-trained spy. From planning an assassination attempt on Hitler in Switzerland to spying on the Japanese in Manchuria and helping the Soviet Union build the atom bomb, Sonya conducted some of the most dangerous espionage operations of the twentieth century.
