Heidi Möhring was skull-smashed on her terrace after a trip to Salzburg with neighbor friend Bärbel. Hansen must leave must of the investigation to Stadler as his rich Hamburg shipping family expects him to entertain short-visiting cousin Wiebke, who soon wanders off to flirt with gentleman innkeeper Jo Caspar. Heidi's niece Lena Obermayer inherits a fortune, covering her recently failed business. She declined neighbor Rainer Bichler's marriage proposal. Instead of robbery traces, a baroque golden signet ring is found, part of a major robbery from a jewelry fair in Traunstein the previous day, so maybe Heidi Möhring and friend's trip was a cover to commit it. A stranger was seen ringing at Heidi Möhring's door, and a strange empty coffer is found.
