The author went to my school and is just a year older than me. We never got to know each other, but I was aware of his story. When he was 13 years old, his insanely rich father got kidnapped for a ransom of 30,000,000 Deutsche Marks and Swiss Franks (around 20 million EUR, adjusted for inflation). Jan, the father, was held in a cellar for around 30 days, while the police went crazy and the emotional rollercoaster of everyone involved was hard to picture. Johann now finally wrote down the whole story from his perspective as a teenager. Makes you feel uneasy.
