Peter Maas presents the true-life thriller about the greatest espionage case in American history - the pursuit, capture, and conviction of the CIA's murderous mole, Aldrich (Rick) Ames. With the full cooperation of the FBI, Maas goes behind the headlines and provides us with an exclusive hour-by-hour, often minute-by-minute, account of how FBI counterintelligence agents, despite set-backs and mishaps, never gave up as they inexorably closed in on Ames and his Colombian-born wife.
