Leonie Soltau has disappeared - 17 years old, daughter of a wealthy industrialist from Wuppertal, and an exemplary student at a private elite high school. Investigators Sandra Santori and Markus Bellers begin their work, but the more they delve into the case, the greater the mystery becomes: Is there a violent crime involved? Was Leonie the victim of a kidnapping? Was it an act of revenge by a former employee of her father? A dispute within the school? Or did the girl simply want to escape her overprotective parents? Leonie remains missing - no confession letter, no ransom note, no farewell letter, no body. Our author Petra Pallandt takes the reader on a thrilling investigation full of speculation, clues, and surprising twists, where each newly found piece of the puzzle changes the entire picture. The novel takes us back into the past.
