Moscow Station is a nonfiction book by Ronald Kessler, the author of Spy vs. Spy. It analyzes how the KGB infiltrated the U.S. Embassy in Moscow and stole top-secret codes. It shows how neglect of American security, from the ambassadorial level down, made this possible.
The book looks at the inner workings of two of the most powerful intelligence agencies in the world. It describes how the Soviet Union rigged bugging devices throughout the entire embassy, including the CIA station.
Kessler combines hard evidence with his own theories. He chronicles the Soviet seduction and sexual entrapment of the young Marines guarding the building. He also covers the incompetence and arrogance of the CIA that led to the security breach.
