Felix Chacaltana Saldivar is a hapless, by-the-book prosecutor living in a small town, six-hundred kilometers from Lima. Until now he has led a life in which nothing exceptionally good or bad has ever happened to him. But when a charred and mutilated body, discovered during Carnival, signals the return of a serial murderer, Saldivar is inexplicably put in charge of the enquiry. As he investigates he must confront what happens to a man, and to a society, when death becomes the only certainty.
