Camilleri Andrea: The Paper Moon

As he gets older, Inspector Montalbano is plagued by existential questions. But he doesn't have much time to wax philosophical before the gruesome murder of a man - shot in the face at point-blank range with his pants down - commands his attention. Add two evasive, beautiful women as prime suspects, dirty cocaine, dead politicians, mysterious computer codes and a series of threatening letters, and things soon get very complicated at the police headquarters in Vigata.
