Ingmar Brix, the father of Jon's girlfriend Maike, is found hanged from the bell rope in the church tower. It soon becomes clear that it was not a suicide. Neither Maike nor the pastor is suspected of the crime, even though the latter flirts with Nora during the interrogation. School principal Kluger is the focus of Jon and Nora's investigation. He is a former friend of Brix's who bought a lighthouse equipped with multiple telescopes for half a million euros. Jon pays Nora her first compliment, and the two begin to appreciate each other's qualities.
