The Shape of Water — Andrea Camilleri

The goats of Vigata once grazed on the trash-strewn site still known as the Pasture. Now local enterprise of a different sort flourishes: drug dealers and prostitutes of every flavor. But their discreet trade is upset when two employees of the Splendor Refuse Collection Company discover the body of engineer Silvio Luparello, one of the local movers and shakers, apparently deceased in flagrante at the Pasture. The coroner's verdict is death from natural causes -- refreshingly unusual for Sicily. But Inspector Salvo Montalbano, as honest as he is streetwise and as scathing to fools and villains as he is compassionate to their victims, is not ready to close the case -- even though he's being pressured by Vigata's police chief, judge, and bishop.

Picking his way through a labyrinth of high-comedy corruption, delicious meals, vendetta firepower, and carefully planted false clues, Montalbano can be relief on, whatever the cost, to get to the heart of the matter.
