The Manchurian Candidate, Richard Condon
Published in 1959, Condon's famous political thriller perfectly reflects the paranoia of the Second Red Scare in America. The novel focuses on Raymond Shaw, a Korean War POW and member of a prominent American political family who has been brainwashed by Communists and used as a sleeper agent. The final scenes, set during a national political convention, are some of the most suspenseful ones in 20th-century American literature. The novel was adapted to film twice, although only the first one, starring Frank Sinatra and Angela Lansbury, is worth watching.
