The Rabanser case
An author who is working on a detective story for a newspaper asks the po- lice to arrest him since he is danger of committing a murder the following day. His self-denunciation is not taken seriously until the murder is ac- tually committed the next day. The author escapes, new crimes are committed and a chain of mysterious events complicates the police's work. It finally turns out that the author's brother is the criminal. He is caught and the author rehabilitated.
