Harper Lee's 'To Kill a Mocking Bird' is a first person narration of Jean'Scout' Louise Finch, where we read the story of Scout and her family. As the protagonist of this story, Scout, starts this story by telling readers about how her brother broke his arm.
Explanation:
Scout was the most loved and commonly addressed nickname of Jean Louise Finch. She was rarely addressed with her real name by any of her family members and people who knew her.
She talks about certain situations where her elder brother Jem broke his arm few years back. She eventually starts telling readers about the history of her family when one of her ancestors fled from England to Alabama where he lived on a farm, named it as Finch Landing. This farm was a primary resource for their family for many years after that, for few generations.
She talks about her father, Atticus, who chose to be a Lawyer and was the first one in the Finch family to not base his primary resource as the farm. He moved to Maycomb to become a Lawyer.
Her father has a brother, Jack, who was a Medicine practitioner in Boston. She also has an aunt, her father's sister Alexandra, who continues to take care of Finch Landing.
She then talks about her mother, who passed away when Jean was two years old. Her memories are very vague in Scout's brain but her elder brother, Jem missed their mother early.
