After the last concert of a long tour, Dr. Kurt Ostbahn retires to his favorite café to relax. He is suddenly dragged into a bizarre criminal case. His vacation then fills with vice, perversion and murder. Of course, this is not just a story; Dr. Kurt Ostbahn experienced everything himself!
The characters are not inventions; they are personal acquaintances of Dr. Ostbahn. Only the names and details have been changed so as to make them barely recognizable. And the story is more exciting than real life.
