Silicon Valley is an espionage innovator—it has been since its inception. During the dawn of the high-tech age, an engineer named James Harper begins his industrious climb. But as Silicon Valley blossoms into what it is today, so too does the dark side of all this newfound wealth and ambition—right as the cold war reaches its final crescendo. As Harper works to build his fortune, his ambition endangers his nation’s safety. He sells nuclear secrets to the Soviet Bloc—intelligence that might still help Moscow in a nuclear exchange today. It would become the chase of a lifetime for San Francisco’s FBI spy hunters. In this series, we’ll walk you through a maze. One of nuclear spying, technology theft, and double agents, and the too wild-to-be-believed events that placed James Harper at the center of this story. And you’ll hear that story from James Harper–the Soviet Bloc spy–himself. Spy Valley is a Project Brazen production.

Thanks for listening to Spy Valley. If you’re looking for a new podcast to follow, we think you’ll enjoy Agent of Betrayal: The Double Life of Robert Hanssen. Listen here for a special preview of the series. Amid the nuclear threat of the Cold War, America's prized secrets were falling into the hands of its sworn enemy—the Kremlin. The FBI's hunt for the leak led to an astonishing discovery—the mole was one of its own, special agent Robert Hanssen. For two decades, Hanssen masqueraded as a devoted patriot while ruthlessly selling out his country, trading classified intelligence to the Soviet Union and later Russia, in exchange for cash and diamonds. He was a whirlwind of contradictions—a self-proclaimed patriot and a traitor; a family man who sexually betrayed his wife; an ardent man of God and a sinner. In this CBS News limited series, CBS News Chief Washington Correspondent Major Garrett delves into the double life of Robert Hanssen and unravels the chilling truth about the most damaging spy in FBI history. Listen to Agent of Betrayal: The Double Life of Robert Hanssen wherever you get your podcasts.
