Murder on Hiddensee - Damp and Rieder are investigating again! The entrepreneur and art collector Werner Gilde has died on Hiddensee. At the open grave, his widow and son accuse each other of having murdered Gilde. The island police officers Ole Damp and Stefan Rieder initially believe that the dispute is only about the inheritance. After all, Gilde owned a valuable, unique art collection featuring works from the Hiddensee Women Artists' Association. But then his best friend, the island painter Hans Kempe, is found dead by the Bodden shore. In his house, the police discover a forgery workshop. The fraud involving artworks seems to be the motive for the murder. And then it turns out that Gilde was also killed. By poison. Damp and Rieder find themselves back at square one in their investigation. "Black Peter" is the fifth case of the unconventional investigator duo Damp and Rieder.
