As was mentioned in the previous post, the narrator of the story is the adult Jean Louise "Scout" Finch. Jean Louise tells the story of how her older brother, Jem, broke his arm when he was nearly thirteen years old. She recalls the incidents leading up to Jem's injury in retrospect and recounts her childhood as an adult. In the opening chapter of the novel, Jean Louise writes,
When enough years had gone by to enable us to look back on them, we sometimes discussed the events leading up to his accident (Lee 5).
This comment gives the reader insight into the fact that the narrator is much older than she is depicted throughout the story. In addition to Jean Louise's opening statements, the story incorporates erudite diction. Scout uses words like "apoplectic" and "philippic" to describe various situations and people. These words would not have been used by a child and indicate that an adult is retelling the story. Another clue that proves an adult Jean Louise is telling the story takes place at the end of Chapter 9. Jean Louise says,
But I never figured out how Atticus knew I was listening, and it was not until many years later that I realized he wanted me to hear every word he said (Lee 56).
