True Believer reveals the life of Noel Field, an American who betrayed his country and crushed his family. Field, once a well-meaning and privileged American, spied for Stalin during the 1930s and '40s. Then a pawn in Stalin's sinister master strategy, Field was kidnapped and tortured by the KGB and forced to testify against his own Communist comrades. How does an Ivy League-educated, U.S. State Department employee, deeply rooted in American culture and history, become a hardcore Stalinist? The 1930s, when Noel Field joined the secret underground of the International Communist Movement, were a time of national collapse: ten million Americans unemployed, rampant racism, retreat from the world just as fascism was gaining ground, and Washington -- pre-FDR -- parched of fresh ideas. Communism promised the righting of social and political wrongs and many in Field's generation were seduced by its siren song. Few, however, went as far as Noel Field in betraying their own country.
