Darkness at Noon - Arthur Koestler

Darkness at Noon's hero is an aging revolutionary, imprisoned and psychologically tortured by the Party to which he has dedicated his life. As the pressure to confess preposterous crimes increases, he relives a career that embodies the terrible ironies and human betrayals of a totalitarian movement masking itself as an instrument of deliverance. Almost unbearably vivid in its depiction of one man's solitary agony, it asks questions about ends and means that have relevance not only for the past but for the perilous present.
