One of Vargas Llosa's major works, it is a portrayal of Peru under the dictatorship of Manuel A. Odría in the 1950s, and deals with the lives of characters from different social strata.  The ambitious narrative is built around the stories of Santiago Zavala and Ambrosio respectively; one the son of a minister, the other his chauffeur.  A random meeting at a dog pound leads to a riveting conversation between the two at a nearby bar known as the Cathedral (hence the title).  During the encounter Zavala tries to find the truth about his father's role in the murder of a notorious Peruvian underworld figure, shedding light on the workings of a dictatorship along the way.

Fujimori eventually won a landslide victory and would remain president for ten years until he was ousted in 2000. The Perpetual Orgy: Flaubert and Madame Bovary (Spanish: "La orgía perpetua.
