Camilleri, Andrea.  
  
  
    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.
