Die dunkle Seite der Bucht

Joe Prohaska, a former detective superintendent from Stuttgart, lives in a tiny village in Istria, where he retired after early retirement. When he receives an anonymous parcel with reference to a murder case that he had worked on many years ago, there can be no question of calm. The culprit had sworn revenge on him at the time. Now he's free again. Prohaska does not believe that the man could become dangerous for him, but he tells Inspector Rossi about it. But Rossi has no time, because on the beach of Punta Corrente the corpse of a stranger washed up. Prohaska decides to get to the bottom of the package himself. He has to take the official photos at a wedding first. But when shortly after the wedding ceremony the groom disappears without a trace, Prohaska suspects that he is once again in the wrong place at the wrong time.
