The Defection Of A.J. Lewinter by Robert Littell

A brilliant and influential American foreign-policy analyst unexpectedly defects to the Soviet bloc, setting off a tense scramble among intelligence officers, journalists, and politicians to uncover his motives and the extent of the damage; the story examines Cold War espionage, moral ambiguity, and the personal and political forces that drive a public figure to betray his country.
