The astonishing true story of the Berlin Tunnel, one of the West’s greatest espionage operations of the Cold War—and the dangerous Soviet mole who betrayed it. Its code name was “Operation Gold,” a wildly audacious CIA plan to construct a clandestine tunnel into East Berlin to tap into critical KGB and Soviet military telecommunication lines. The tunnel, crossing the border between the American and Soviet sectors, would have to be 1,500 feet (the length of the Empire State Building) with state-of-the-art equipment, built and operated literally under the feet of their Cold War adversaries. Success would provide the CIA and the British Secret Intelligence Service access to a vast treasure of intelligence. Exposure might spark a dangerous confrontation with the Soviets. Betrayal in Berlin is Steve Vogel’s in depth account of the operation. He vividly recreates post-war Berlin, a scarred, shadowy snake pit with thousands of spies and innumerable cover stories. It is also the most vivid account of George Blake, perhaps the most damaging mole of the Cold War.  Steve talks to host Jim Fausone about this amazing story.
