Spies

"This important new book . . . based on archival material . . . shows the huge extent of Soviet espionage activity in the United States during the 20th century" (The Telegraph).

Based on KGB archives that have never been previously released, this stunning book provides the most complete account of Soviet espionage in America ever written. In 1993, former KGB officer Alexander Vassiliev was permitted unique access to Stalin-era records of Soviet intelligence operations against the United States. Years later, Vassiliev retrieved his extensive notebooks of transcribed documents from Moscow. With these notebooks, John Earl Haynes and Harvey Klehr have meticulously constructed a new and shocking historical account.

Along with valuable insight into Soviet espionage tactics and the motives of Americans who spied for Stalin, Spies resolves many long-standing intelligence controversies. The book confirms that Alger Hiss cooperated with the Soviets over a period of years, that journalist I. F. Stone worked on behalf of the KGB in the 1930s, and that Robert Oppenheimer was never recruited by Soviet intelligence.

Uncovering numerous American spies who never came under suspicion, this essential volume also reveals the identities of the last unidentified American nuclear spies. And in a gripping introduction, Vassiliev tells the story of his notebooks and his own extraordinary life.
