Duncan Chaplain Lee was an unlikely traitor. A Rhodes Scholar, patriot, and descendent of one of Americas 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 Stalins most valuable moles in U.S. intelligence, passing the KGB vital information on everything from the D-Day invasion to Americas 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, Perry's book 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.
