The famous author Mark Storm's publisher is unhappy with his books and asks him to write books in a more popular genre, crime for example. When Mark Storm comes to his apartment, he finds a burglar, Kurre. He notices that they have a physical similarity and they change identity, which makes it possible for Storm to make empirical studies in the world of crime.
