We’re watching Fat Leonard’s case closely. In the meantime, we have a new investigative podcast to share with you: Spy Valley: An Engineer's Nuclear Betrayal. This new series uncovers Silicon Valley’s origins as a laboratory for espionage — and this is a special preview of episode one.

At the dawn of the hi-tech age, Moscow’s spies opened up shop in San Francisco and Silicon Valley. In this podcast, you’ll get to know the group of FBI spy hunters who assembled to stop them—and solve the case of a lifetime. Hosted by national security journalist Zach Dorfman, Spy Valley will walk you through a maze of technology theft, double agents, and unbelievable events that put an American engineer at the center of it all.
