Spy tells, for the first time, the full, authoritative story of how FBI agent Robert Hanssen, code name grayday, spied for Russia for twenty-two years in what has been called the "worst intelligence disaster in U.S. history"--and how he was finally caught in an incredible gambit by U.S. intelligence.

David Wise, the nation's leading espionage writer, has called on his unique knowledge and unrivaled intelligence sources to write the definitive, inside story of how Robert Hanssen betrayed his country, and why.

Spy at last reveals the mind and motives of a man who was a walking paradox: FBI counterspy, KGB mole, devout Catholic, obsessed pornographer who secretly televised himself and his wife having sex so that his best friend could watch, defender of family values, fantasy James Bond who took a stripper to Hong Kong and carried a machine gun in his car trunk.
