Der Bartmeister

Hubert and Girwidz are called to a luxury hotel to investigate property damage; apparently, someone went on a rampage that morning. The guest staying in the room is a beard model who was planning to enter a contest. But now he's lying dead in the bathroom.

The murder weapon is quickly found: a straight razor engraved with a name. But it's Girwidz's name, of all people! He explains that he recently ordered the razor from the blacksmith Heiko Geiß. The blacksmith apologizes for the mix-up. He accidentally gave Girwidz's razor to the Dutch barber Wim van Dijk, one of the judges for the upcoming competition. But the barber is currently on a raft trip down the Isar River. Riedl is to take up the pursuit in plain clothes.

Meanwhile, Hubert and Girwidz question the other judges. Markus Schafbauer, head of an advertising agency, explains that the competition is a farce because, at the request of the client Kimberly Pfeiffer, the winner had long since been decided: the dead man.

When it turns out that Riedl had been walking around all day wearing—of all things—the victim's bathrobe, the investigators finally get on the trail of the mystery.
