The Catcher Was A Spy by Nicholas Dawidoff

The Mysterious Life of Moe Berg

A scrupulous portrait of an enigmatic American who lived two lives: a major-league catcher known for his inscrutable demeanor and a highly educated, polyglot operative recruited by wartime intelligence to penetrate Nazi scientific projects. The narrative traces his improbable trajectory from Ivy League graduate and professional athlete to OSS agent sent to assess — and, if ordered, neutralize — the German atomic program, while exploring the contradictions of his personality, the moral ambiguities of espionage, and the secrecy that shrouded his postwar years.
