Work turns toxic for a Venice, Italy police detective in this novel in the award-winning, New York Times-bestselling series. Incinerators across the south of Italy are at full capacity, burning who-knows-what and releasing unacceptable levels of dangerous air pollutants, while in Naples, enormous trash piles grow in the streets. In Venice, with the polluted waters of the canals and a major chemical complex across the lagoon, the issue is never far from the fore. Then, after an investigator from the Carabiniere, looking into the illegal hauling of garbage, asks for a favor, Guido Brunetti finds himself in the middle of an investigation into murder and corruption even dirtier than the air and water . . .
