Acqua Alta by Donna Leon
In this gripping installment of a celebrated mystery series set in Venice, the protagonist, a thoughtful and diligent detective, finds himself embroiled in a complex case that intertwines a brutal attack on a famous opera singer with a sinister burglary at a local museum. As the detective delves deeper into the investigation, navigating the atmospheric and flood-prone streets of Venice, he uncovers a web of deceit, corruption, and long-buried secrets. With the city's unique and treacherous acqua alta (high water) providing both a backdrop and a clue, the detective must use all his skills and local knowledge to solve the case before the rising waters erase all traces of the perpetrator's crimes.
