He also tells them that the Duke has been driven away by a "officious man" who used an "unknown method" to make the Duke quit. He says that the man is a rookie and that the feudal authorities would not hire "a rookie." The Prefect says that he will make the young man realize how perilous "the underworld is" and that he has "a surefire plan" for him.
