Murder without a Body - a woman disappears without a trace. An unknown person abducts children from school camps. The police search for many years for the murderers of eight Turks and one Greek. All of these are cases from the daily life of case analyst Alexander Horn - cases in which the police faced significant puzzles and sought advice from him and his team. Alexander Horn illustrates, through the example of sensational criminal cases, how case analysis works systematically, and he explains what goes on in the minds of murderers who commit horrific crimes.
