The redhead girl is a character introduced about halfway into the book. She is impulsive, in that she decides to take Jaromil as a lover after her friend leaves Prague to get married. Later, in a short chapter near the end of the book, the narrator reveals that at the same time, the red-head girl has a middle-aged man as a lover, who she sees once a month, and possibly other lovers. The red-head girl makes up the story that her brother Jan is about to defect and flee from the country. She tells this to Jaromil because she wants to keep him from breaking up with her. Little does she know that Jaromil will tell the story to the police, and she and her brother will be arrested.
