Van der Valk is on the case again as a mysterious letter is unearthed alluding to the murder of a man named Cabestan. In the letter, the murderer is named but van der Valk must find out first who this mysterious letter-writer is. What transpires is a tale of deception and adultery as the rich Carl Merckel, the managing director of the Lutz Brothers merchant bank, lays an accusation of cold blooded homicide of which, he claims, his wife had no part to play.
