One morning, the alternative practitioner Raffael Lembeck is found dead by his wife Stella on a restored farm near Wolbeck. The victim had obviously fallen in his practice and then bled to death, explains Prof. Boerne at the scene of the crime. Lembeck's alternative treatment methods were particularly popular with women, and wealthy patients even came from abroad. On the other hand, on the neighboring farm, with the family of farmer Moritz Kintrup, he was not always welcome. There are also the three Krien brothers in Wolbeck, who don't really want to reveal what they had to do with the victim.
