This hilarious extravaganza presumes the existence of a secret society of revolutionaries sworn to destroy the world. There are seven members of the Central Anarchist Council who, for reasons of security, call themselves by the names of the days of the week — Sunday, Monday, and so on. But events soon cast a doubt upon their real identities, for Thursday (the Man Who Was Thursday) is not the passionate young poet he appears to be, but a Scotland Yard Detective. Who and what are the others? Chesterton unravels the fantasy in his own inventive and exuberant way and then uses this nightmare of paradox and surprise to probe the mysteries of human behaviour and belief.
