Betrayal is the remarkable story of the last American spy of the cold war: Aldrich "Rick" Ames, the most destructive traitor in the history of the Central Intelligence Agency.

Tim Weiner, David Johnston, and Neil A. Lewis, reporters for The New York Times, tell how the barons of the CIA could not believe that its headquarters harbored a traitor. For years, the Agency was baffled by a wily Russian spymaster who played a high-stakes chess game against the Americans, deceiving the CIA into thinking that there were other moles -- or no moles at all.

It took nearly eight years for the CIA to share the full facts of the scenario with the Federal Bureau of Investigation. Once they knew those facts, the men and women of the FBI tracked Ames day and night for nine months before they arrested him. They tell their story here in astonishing detail for the first time.

The interviews are entirely on-the-record. There are no pseudonyms, anonymous quotes, or invented scenes. The men betrayed by Ames were real people, and the stories of their lives are the true history of the espionage game in the waning years of the cold war.
