The Third Policeman is Flann O'Brien's comic novel about the nature of time, death, and existence. Told by a narrator who has committed a botched robbery and brutal murder, the novel follows him and his adventures in a two-dimensional police station where, through the theories of the scientist/philosopher de Selby, he is introduced to "Atomic Theory" and its relation to bicycles, the existence of eternity (which turns out to be just down the road), and de Selby's view that the earth is not round but "sausage-shaped." With the help of his newly found soul named "Joe, " he grapples with the riddles and contradictions that three eccentric policeman present to him.
