Death of the Singing Fish

On a picturesque island, in a sugar-white house, in the middle of a large private lake in the Alps, the body of a young woman is found, just as private detective Karel Schwarz and his beautiful assistant Maria are vacationing with friends on a golf course nearby. No one is claiming the corpse, especially not the owner of the romantic nature area, who obviously doesn't even know her. The Swiss police are clueless, so they turn to a pair of Czech detectives out of familiarity. They identify the murdered girl almost immediately because they recognize her as one of the actresses from a popular Czech television series. It soon becomes clear that her mysterious death is far from the only one.
