'I spy': How a prisoner swap helped end decades of tensions between the US and Cuba

An American private contractor arrested in Havana. Cuban intelligence agents serving long prison sentences in the United States. And a spy swap that sets the stage for a historic rapprochement between the US and Cuba. It sounds like a Hollywood thriller but it's all true. The story unfolds in a new eight-part podcast from Audible and Foreign Policy magazine called "I Spy: The US, Cuba and the Secret Deal That Ended the Cold War." Host Marco Werman learns more from the series creator, Dan Ephron, who is the executive editor of Foreign Policy magazine.
