A hiker is found dead in a remote forest that is popularly known as the "Murder Hole". Opposite the victim is a melting snowman with one eye missing. The start of a series of murders in the forest area near Freudenstadt. The handwriting is always the same: all victims show frostbite, while the left eye is covered with a black gem. The investigative team Maris Bächle and Konrad Diener has Florentin Sneelin in its sights, a reproductive doctor who lives in a romantic moated castle whose ice cellar not only stores champagne. The suspect knew the victims from a stay in a children's home many years ago. The teachers there enforced discipline and order using sometimes sadistic methods. Their wards did the same. There was a strict caste system among the children. Sneelin belonged to the lowest caste. He was a so called "Snow Child", one that his mother wanted "to foist" on his father.

The corpse of a fruit farmer is found in a meadow orchard. It was buried upside down, draped like a scarecrow. The spectacular staging of the murder leads Commissioner Maris Bächle and her colleague Konrad Diener to suspect a personal motive. While the black asylum seeker is quickly suspected as a perpetrator, the Freudenstadt inhabitants speculate behind closed doors about the involvement of earth spirits - of course, just for fun.

She had mysteriously survived there. With the help of the city archivist, the two investigators come across an old legend about forest spirits and an old place of execution in the middle of the forest. The forest court once met in this mystical place. Apparently it is active again.
