Gabriel Syme is a poet recruited to infiltrate the Central Council of Anarchists. In the strange suburb of Saffron Park, he meets Lucian Gregory, an anarchist who celebrates destruction in verse. But Syme is a detective in disguise, and his true mission is to become Thursday among seven revolutionaries who call themselves by the days of the week. As he descends deeper into their ranks, the anarchists grow more brilliant and more terrifying, culminating in Sunday, their enigmatic leader whose power seems to transcend the group itself. What unfolds is a fever-dream of logic and lunacy, a chase through Edwardian London that questions not only who the anarchists are, but whether order and chaos are truly opposites, or perhaps the same thing wearing different masks. The novel builds to an ending so strange and daring it has haunted readers for over a century. This is Chesterton at his most playful and most profound: a thriller that is also a philosophical joke, an allegory about good and evil that refuses to end where you expect.
