During the interrogation of an entitled, arrogant man suspected of giving drugs to a young girl who then died, Commissario Guido Brunetti acts rashly, doing something he will quickly come to regret. In the fallout, he begins to doubt his career choices and realises that he needs a break, needs to get away from the stifling problems of his work. Granted leave from the Questura, Brunetti is shipped off by his wife, Paola, to a villa owned by a wealthy relative on Sant’Erasmo, one of the largest islands in the Venetian laguna. There he intends to pass his days rowing, and his nights reading Pliny’s Natural History. The recuperative stay goes according to plan and Brunetti is finally able to relax, until Davide Casati, the caretaker of the house on Sant’Erasmo, goes missing following a sudden storm. Nobody can find him – not his daughter, not his friends, and not the woman he’s secretly been visiting.
