G. K. Chesterton The Man Who Was Thursday

Sometimes described as thrilling, sometimes as comic, and sometimes as metaphysical or spiritual, The Man Who Was Thursday is perhaps a little of each. The tale begins when an undercover policeman infiltrates a mysterious Anarchist group. As the novel progresses, things become more comic and improbable, and eventually evolve in to a sort of abstract, dreamlike state. Filled with Christian allegory, Thursday is a glittering, fascinating exploration of good versus evil and theology through the lens of adventure, wit, and the surreal.
