Agent Sonya by Ben Macintyre

From planning an assassination attempt on Hitler in Switzerland, to spying on the Japanese in Manchuria, to preventing nuclear war (or so she believed) by stealing the science of atomic weaponry from Britain to give to Moscow, Ursula conducted some of the most dangerous espionage operations of the twentieth century.

In Agent Sonya, Britain’s most acclaimed historian Ben Macintyre delivers an exhilarating tale that’s as fast-paced as any fiction. It is the incredible story of one spy’s life, a life that would alter the course of history . . .
