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.
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..
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.
