Through a Glass, Darkly: A Commissario Guido Brunetti Mystery, Paperback/Donna Leon

On a luminous spring day in Venice, Commissario Guido Brunetti and Inspector Vianello play hooky to help get Vianello s friend Marco Ribetti an environmental activist arrested during a protest against toxic waste being dumped into the city s waters released from prison. But on the steps of the police headquarters, they come face-to-face with Ribetti s cantankerous father-in-law, who has been overheard making threats against Ribetti. And when the body of a night watchman is at the father-in-law s glass factory next to an annotated copy of Dante s Inferno, Brunetti must find out if there is a connection between this and whoever is ruining the waters of the lagoon."
