Girl of His Dreams. (Brunetti 17), Paperback/Donna Leon

One rainy morning Commissario Brunetti and Ispettore Vianello respond to an emergency call reporting a body floating near some steps on the Grand Canal. Reaching down to pull it out, Brunetti's wrist is caught by the silkiness of golden hair, and he sees a small foot - together he and Vianello lift a dead girl from the water.
