The murder and kidnapping of a little girl – this is another case of the Viennese murder party. At first, Isabell's father doesn't want to hear about the police. He fears for his daughter's life, and would rather accede to the blackmailer's demands and forfeit the twenty million ransom than endanger the child in any way. Commissioner Moser will have to make a considerable diplomatic effort to convince Mr König of the need for cooperation. Will the terrified father understand that without the help of detectives, the little girl has little chance of survival? But one thing is already clear: by the time the investigation is concluded, everyone involved will have a very hot time.
