A young American girl is found dead in Gota Kanal, Swedens largest channel. Since there are hardly any clues or evidence at all it seems as if the murder cant be solved. Martin Beck and his men are assigned to the case. Soon they find a likely suspect and together with a police woman they begin a cat and mouse game to catch him.
