Circle of treason [electronic resource] : a CIA account of traitor Aldrich Ames and the men he betrayed / Sandra Grimes and Jeanne Vertefeuille

One of the most destructive traitors in American history, CIA officer Aldrich Ames provided information to the Soviet Union that contributed to the deaths of at least ten Soviet intelligence officers who spied for the United States. In this book, the two CIA officers directly responsible for tracking down Ames chronicle their involvement in the hunt for a mole. Considering it their personal mission, Sandra Grimes and Jeanne Vertefeuille dedicated themselves to identifying the traitor responsible for the execution or imprisonment of the Soviet agents with whom they worked. Their efforts eventually led them to a long-time acquaintance and coworker in the CIA's Soviet-East European division and Counterintelligence Center, Aldrich Ames. Not only is this the first book to be written by the CIA principals involved, but it is also the first to provide details of the operational contact with the agents Ames betrayed. Among those agents was GRU Gen. Dmitriy Fedorovich Polyakov, the highest-ranking spy run by the U.S. government during the Cold War. Described as the "Crown Jewel," Polyakov provided the United States with a treasure trove of information during his 20-plusyear history of cooperation. The general's story, along with those of other GRU and KGB officers, including Col. Leonid Georgiyevich Poleshchuk and Col. Vladimir Mikhaylovich Piguzov, and Sergey Vorontsov are revealed for the first time in detailed operational histories by the authors who worked on their cases. The book also covers the aftermath of Ames's arrest, including the Congressional wrath for not identifying him sooner, the FBI/CIA debriefings following Ames's plea bargain, and a retrospective of Ames the person and Ames the spy. Now retired from the CIA, Grimes and Vertefeuille are finally able to tell this inside story of the CIA's most notorious traitor and the men he betrayed.
