The Unmasking of Robert Hanssen, the Most Dangerous Double Agent in FBI History.
Robert Philip Hanssen was one of the FBI's most trusted agents, a twenty-five-year veteran who was a devout Catholic and devoted suburban family man, who attended the same church and sent his children to the same school as his boss, bureau director Louis J Freeh.
But as he rose up the ranks to become one of America's foremost counter-intelligence experts, he was also leading another life as a devilishly clever spy for the Russian government, selling secrets that would destroy billions of dollars of painstaking intelligence work and compromise a host of America's most closely guarded national security secrets, including the names of clandestine operatives and the top-secret-survival plan in the event of nuclear attack.
Now, Pulitzer Prize-winning journalist and author David A Vise untangles Hanssen's web of deceit to tell the story of how he avoided detection for decades while becoming the most dangerous double agent in FBI history.
