THE LIAR: How a Double Agent in the CIA Became the Cold War's Last Honest Man

In the mid-1970s, the CIA and KGB watched Karel Koecher closely. They were both convinced he was working for the enemy. And they were both right. Traveling with his wife, Hana, he posed as a Czechoslovak asylum seeker and arrived in the U.S. as a Communist sleeper agent. After getting a job at the CIA, he proceeded to operate as a double agent at the height of the Cold War. Photos.
