Temporary Perfections — Gianrico Carofiglio

The electrifying best-selling crime thriller from Italy, available for the first time in English. An instant sensation and number-one best seller since its publication, Temporary Perfections is the fourth crime novel by former Italian prosecutor Gianrico Carofiglio to feature Guido Guerrieri. A lawyer practicing in Bari, in southwest Italy, Guido Guerrieri is hired by an old colleague to work a missing-persons case that the police have failed to solve. Manuela Ferraro disappeared six months ago after spending a September weekend at a beach resort; as Guerrieri digs deep into her life and activities, he stumbles into a sinister drug ring and the real truth about why Ferraro vanished.
Simultaneously thoughtful and suspenseful, this is crime fiction at its best.
