First published in 1952, Witness was at once a literary effort, a philosophical treatise, and a bestseller. Whittaker Chambers had just participated in America's trial of the century in which Chambers claimed that Alger Hiss, a full-standing member of the political establishment, was a spy for the Soviet Union. This poetic autobiography recounts the famous case, but also reveals much more. Chambers' worldview--e.g. "man without mysticism is a monster"--went on to help make political conservatism a national force.

Alger Hiss (November 11, 1904 – November 15, 1996) was an American government official accused in 1948 of having spied for the Soviet Union in the 1930s. Statutes of limitations had expired for espionage, but he was convicted of perjury in connection with this charge in 1950.
