Benjamin Cunningham is a journalist, writer and PhD candidate at the Universitat de Barcelona. His book “The Liar: How a Double Agent in the CIA Became the Last Honest Man of the Cold War” during 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, Koecher posed as a Czechoslovak asylum seeker and arrived in the US as a Communist sleeper agent. After parlaying a doctorate from Columbia into a job at the CIA, Koecher proceeded to operate as a double agent at the height of the Cold War.
