The New York Times–bestselling “first-rate spy thriller” of the FBI agent who sold top-secret information to the Russians for more than twenty years (Entertainment Weekly). Drawing from a wide variety of sources in the FBI, the Justice Department, the White House, and the intelligence community, Pulitzer Prize–winning author David A. Vise tells the story of how FBI counterintelligence agent Robert Philip Hanssen employed the very sources and methods his own nation had entrusted to him in a devious game of deceit—simply because he had something to prove. Vise also interweaves the narrative of how FBI director Louis J. Freeh led the government’s desperate search for its betrayer among its own ranks, from the false leads, to the near misses, to its ultimate, shocking conclusion. Fascinating, gripping, and provocative, The Bureau and the Mole is a harrowing tale of how one man’s treachery rocked a fraternity built on fidelity, bravery, and integrity—and how the dedicated perseverance of another brought him to justice. “Absorbing . . . Vise’s account of Mr. Hanssen’s road to becoming a double agent is fascinating.” —Michiko Kakutani, The New York Times
