Darkness at Noon
How a true believer in the revolution is brought to confess to crimes he did not commit. Koestler's 1940 novel about Stalinist show trials stages a great philosophical confrontation: the logic of the party versus the last gasp of individual conscience. Rubashov's interrogation scenes rank among the finest dialogue in 20th-century fiction. Modern Library placed it eighth.
Schematic by design: Rubashov, Ivanov, and Gletkin are positions first and people second, and the novel sometimes reads as a Platonic dialogue with cells. Arlova, the one woman, exists to be sacrificed offstage. For eighty years English readers also got a hurried translation by a 22-year-old sculptor; the German original was lost until 2015.
The case for it and the rest of the canon open with Pro.
