Girwidz attends a cooking school class and discovers the body of cooking school owner Matthias Brehm in the basement of the house. Dr. Caroline Fuchs determines "death by biogas." This leads the investigation to a local biogas plant. But then Riedl is found unconscious in his car - with a sack of "Wolfratshauser Königsblau" potatoes, the same variety that Brehm also loved to cook with.
