Ines Fellmann, a young city guide was found dead one morning in Rosenheim. Apparently she was booked for a „Moonshine Tour“ the previous evening. The inspectors Sven Hansen and Korbinian Hofer start investigating. The city guide had a date with restaurateur Ulrich Reiter that evening. It turns out that Reiter had an affair with the victim, so Judith Gerkes, Fellmann’s colleague, comes under suspicion. Did Gerkes, Reiter’s girlfriend kill Fellmann because she was jealous when she found out about the affair?
There are also traces that lead to Brigitte Hartung who retired as a city guide to pursue a career as a writer. When she worked as a city guide she supplied restaurateur Reiter with a lot of tourists and good customers. Did she take money for these favours and did Ms Fellmann find out? Did Reiter or Hartung help to clear things up? During Hofer’s and Hansen’s investigation, they meet Cosima von Windacker again. The PR agent was assigned to modernise the city tours in Rosenheim. After Ms Fellmann’s death she is desperately looking for a replacement and who would be better suited for the job than Marie?
