The Spy Who Came in from the Cold (1963)Read about another entry on the list.
In his cold war novel, adapted as a film starring Richard Burton, John Le Carré sets his denouement in an East German courtroom where the spy Alec Leamas learns the real reason for his mission behind the Berlin Wall. It isn’t strictly speaking a courtroom drama but earns its place for the power of the concluding line of Chapter 23. “And suddenly, with the terrible clarity of a man too long deceived, Leamas understood the whole ghastly trick.” Leamas realises how he has been used by the British Secret Service at just the moment the reader realises: superb.
