The only Major League ballplayer whose baseball card is on display at the headquarters of the CIA, Moe Berg has the singular distinction of having both a 15-year career as a catcher for such teams as the New York Robins and the Chicago White Sox and that of a spy for the OSS during World War II. Here, Dawidoff provides a careful and sympathetic biography (Chicago Sun-Times) of this enigmatic man. Photos.From the Trade Paperback edition.
