Betrayal in Berlin - The True Story of the Cold War's Most Audacious Espionage Operation

"A riveting and vivid account. ... A remarkable story. ... It reads like a Hollywood screenplay." -Foreign AffairsThe 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.
Yet as the Allies were burrowing into the German soil, a traitor, code-named Agent Diamond by his Soviet handlers, was burrowing into the operation itself.
