"Duncan Chaplin Lee was one of the highest-ranking moles in the wartime U.S. intelligence apparatus. Lee was chief aide to William "Wild Bill" Donovan, the fabled head of the Office of Strategic Services and grandfather of the CIA. During World War II, Lee's political sympathies and desire to advance the fight against fascism led him to leak highly classified information to the Soviets. J. Edgar Hoover would tirelessly trace Lee's movements in an attempt to prove his guilt. A Very Principled Boy shows just how deeply Soviet spies were entrenched in the American intelligence community at the height of the Cold War" "Duncan Chaplain Lee was an unlikely traitor. A Rhodes Scholar, patriot, and descendent of one of America's most distinguished families, he was also a communist sympathizer who used his position as aid to intelligence chief "Wild Bill" Donovan to leak critical information to the Soviets during World War II. As intelligence expert Mark A. Bradley reveals, Lee was one of Stalin's most valuable moles in U.S. intelligence, passing the KGB vital information on everything from the D-Day invasion to America's plans for postwar Europe. Outwitting both J. Edgar Hoover and Senator Joseph McCarthy, he escaped detection again and again, dying a free man before authorities could prove his guilt. A fast-paced cat-and-mouse tale of misguided idealism and high treason, A Very Principled Boy draws on thousands of previously unreleased CIA and State Department records to reveal the riveting story of one of the greatest traitors of the twentieth century"
