S3, E8: Guitarist Robert Köhler is found beaten to death in front of the farmhouse where he lives with his girlfriend, Tessa Meidinger. Tessa and Robert were not only a couple in private, they also played together in a band. Tessa was thinking of leaving the group and starting a solo career with the help of the shady music manager Klaus Zimmer. Robert wanted to prevent this at all costs. However, for Zimmer, who is on the verge of bankruptcy, the talented musician is the last chance. Was her decision-making process perhaps accelerated by the murder of Robert? When the inspectors find out that Robert apparently had a secret affair, Tessa herself comes under suspicion. Another band member, drummer Nico Bresnach, also plays a role in the whole story: he had anonymously informed Tessa about Robert's affair. In the end, the whole story turns out to be rather "beastly". It is Tessa's disappeared cat and a talking parrot that lead them to the decisive clue.
