The dead must have their number

In the garden of an old college in Leuven, some playing children find the naked body of a young woman who has been killed in a particularly brutal way. The perpetrator has given her a bizarre attribute, together with a mysterious sentence that suggests that he will not stop at this one victim. Chief Inspector Thomas Berg wonders in vain why the murderer has acted in such a gruesome way and what significance a few numbers have that keep cropping up during the investigation. The case becomes even more incomprehensible when it turns out that the perpetrator has sent a photo of his victim to a local TV station. A few days later, Berg's worst fears are realized when a second woman is found. She has been murdered in the same brutal way and again the body has been provided with a strange attribute and a short sentence. The pressure to solve the murders becomes almost unbearable for Berg and his team, especially when the fear among the population grows that the murderer has no intention of stopping yet.
