On a full moon night, an assassin goes in search of his victim. A girl is sexually abused and killed in an embankment on the outskirts of a city. A police inspector, whose wife is confined to a mental ward, draws up his only objective: to find the assassin before he commits another fatal attack. Plenilunio has an electrical narration full of tension, rage, and tenderness. It is a necessary work in which the author reaches a truly overwhelming literary maturity.
