The cases that Klara Blum, Kai Perlmann and Matteo Lüthi are dealing with in the last Lake Constance "crime scene" are strange and full of mysteries.

If you look at the poisoninginvestigating an investment fraudster, even if you didn't wish him any well-being. When you meet three old wise maidens who could be witches or saints. Lüthi, Perlmann and Blum are investigating in a world where thousands of workers are being burned to death and the culprit is bathing in crocodile tears. What is worth living for is, as Klara Blum says, "that there is justice". And that's not the last word.
