GK Chesterton's 1908 masterpiece is an intriguing mix of thriller, farce and gothic romance. English original edition. "Whenever possible Chesterton made his points with popular sayings, proverbs, allegories-first carefully turning them inside out". (Time Magazine). The Central Anarchist Council is a secret society sworn to destroy the world. The council is governed by seven men, who hide their identities behind the names of the days of the week. Yet one of their number - Thursday - is not the revolutionary he claims to be, but a Scotland Yard detective named Gabriel Syme, sworn to infiltrate the organisation and bring the architects of chaos to justice. But when he discovers another undercover policeman on the Council, Syme begins to question his role in their operations. And as a desperate chase across Europe begins, his confusion grows, as well as his confidence in his ability to outwit his enemies, unravelling the mysteries of human behaviour and belief in a thrilling contest of wits.
