Sophie is surprised – and Bärbel explains to her: The reason why Heike and Dietmar have been so distracted lately is the giftedness of their son Kevin. And since he has problems with the "normal" school thanks to his oversized IQ, he is supposed to move into the elite boarding school Lobberich, which is very close to Hengash. Even before Kevin is accepted there as a scholarship holder, his future teacher Dr. Kroy stupidly drops dead: heart attack – at least says Dr. Bechermann, the gynecologist of the district, who is all too often active in the emergency service. However, the autopsy reveals that it is not a natural death, because Kroy's teaching staff contains a huge amount of cocaine, which was apparently not taken consciously. So murder after all. Since Kroy enjoyed great unpopularity, there are also plenty of students and colleagues who could have been trusted with the deed.
