Lessing - 06 - Der kalte Fritte

The billionaire Alonzo Sassen is murdered when his villa in Weimar is broken into. His young wife Lollo shoots the perpetrator - apparently in self-defense. Inspectors Kira Dorn and Lessing observe Lollo, who then looks for work in the "Chez Chériechen" brothel, which is run by Fritjof "Fritte" Schröder. His brother Martin runs a quarry near Weimar with his wife Cleo, which is on the verge of bankruptcy. As a special geological formation, this is one of the two potential locations for the planned "Goethe Geomuseum". This use would save the Schröders financially. But Sassen had announced that he would give the city a piece of land in Weimar's best location, on Frauenplan, so that the museum could be built there.
Was that his death sentence? Their investigations lead Kira Dorn and Lessing to the Bauhaus University. Architecture professor Ilja Bock chairs the jury that decides on the location of the new museum building. He has an affair with his childhood sweetheart Cleo, which puts her in the detectives' crosshairs. When it turns out that Fritte Schröder is at the table at the property roulette and the hate relationship with his brother Martin becomes apparent, the case is heading for an explosive finale.
