The body of a young woman is found on the shores of Lake Constance. The next day, her superior, the biotech luminary and Nobel Prize winner Bernd Eschenbach, is discovered dead in the lake - bound hand and foot. The old legend, according to which delinquents once received their just punishment by being tied up and thrown into the lake off the gallows island near Lindau, is given a new twist. A mysterious case begins for police sergeant Annika Wagner and her colleague Martin Keller. And Robert Anders is also drawn deep into the investigation, as the victim was an old school friend of his.
