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.
