The 18th installment of Leon's wickedly entertaining series featuring Commissario Guido Brunetti (after 2008's The Girl of His Dreams) focuses on garbage, illuminating the author's ongoing concern about the environment. Venice contends with polluted canals and a huge chemical complex. Trash litters Naples' streets. Incinerators in south Italy are full, and trucks laden with toxic waste travel the roads. Brunetti becomes an ecological expert when an investigator with the carabiniere wants him to look into illegal hauling that has resulted in a truck driver's murder. On a personal level, Brunetti's father-in-law asks him to investigate a potential business partner, Maurizio Cataldo. But Brunetti, who's devoted to his wife and children, is more intrigued by Cataldo's much younger second wife, whose once beautiful looks were ruined by a face lift. Leon flawlessly melds the two plot threads as she parallels her characters' vulnerability with that of Venice.
