Originally published in 2005 as: La luna di carta.

The moody Inspector Montalbano is further beset by the existential questions that have been plaguing him of late. But he doesn't have much time to wax philosophical before the gruesome murder of a man--shot at point-blank range in the face with his pants down--commands his attention. Add two evasive, beautiful women as prime suspects, some dirty cocaine, mysterious computer codes, and a series of threatening letters, and things soon get very complicated at the police headquarters in Vigàta.
