The codebreakers who unraveled the Soviet spy network. In 1943, a 22-year-old teacher named Gene Grabeel arrived at a mysterious Army facility outside Washington, where she was given drawers full of meaningless five-digit numbers and asked to sort them. Though she didn't know it at the time, turns out those numbers were Soviet intelligence cables protected by a cipher thought to be mathematically unbreakable. She and her colleagues would eventually crack open the Venona project—and pull off perhaps the biggest counter-espionage breakthrough of the Cold War.
