Discworld Noir

Ankh-Morpork is a city surrounded by darkness, where the cold river Ankh flows, where it always rains, and where dwarves and trolls coexist with secret societies, religious fanatics, stupid police captains and bar pianists. It is also the place where a bitterly sarcastic and sharp-eyed private detective named Lewton tries to make a living solving bizarre cases. A mysterious woman named Carlotta hires him to find her lost lover. As he roams the dark city gathering evidence, Lewton must solve the case, confront a sinister conspiracy, and is once again torn between love and despair.
