In the quiet English village of Great Rollright in 1945, neighbors knew her simply as Mrs. Burton-a pleasant woman with a slight accent who baked excellent cakes. None suspected that behind this carefully crafted persona was Colonel Ursula Kuczynski of the Red Army-one of the most consequential spies in history. While hanging laundry and tending to her children, she was simultaneously transmitting atomic secrets to Moscow from a radio hidden in her outdoor privy. This extraordinary woman-code-named "Sonya"-had conducted espionage across China, Poland, and Switzerland before settling in Britain, where she ran a network of communist spies inside the country's atomic weapons program. Her intelligence enabled the Soviet Union to build its own nuclear bomb years ahead of schedule, forever altering the Cold War's balance of power. How could one woman-simultaneously mother, housewife, novelist, radio technician, and secret agent-change the course of history while remaining virtually invisible to those around her?
