Golf coach Toni Brendel is found dead on the Berchtesgaden golf course. Everything points to murder. Toni Brendel, who wanted to influence the future of the golf club with ambitious construction plans, did not have only friends. Club president Julius Greiner, who wanted to prevent Toni's plans and whose reputation was damaged by Toni's slander, is just as much a suspect as Toni's betrayed wife Pia Brendel and his mistress Franziska Schachtner.

In the course of the investigation, many motives and clues emerge, but there is no evidence. Only after Toni's past has been examined more closely and Beissl has resorted to an unconventional criminalistic ruse can the perpetrator be unmasked.

The owner of a newly renovated hotel is found dead. He fell to his death from the window of his office. The safe in the office has been broken into. Everything points to a robbery-murder. Beissl and Jerry quickly come up with a possible motive: the victim consistently refused to pay the tradesmen involved in the renovation.

Beissl and Jerry are confident that they will find the murderer among the cheated craftsmen. One of the victims increasingly becomes the focus of the investigation: a master carpenter who is a friend of Beissl's. But the resolute boss of the painting company is also under suspicion. Did she take the money from the safe? Both firmly reject the suspicions. But what if it wasn't one of the craftsmen? The hotel's long-time concierge also comes under scrutiny in the investigation.
