To kill a Mockingbird is a novel published in 1960 by Harper Lee and takes place during three years (1933–35) of the Great Depression, in the fictional town of Maycomb, Alabama. It focuses on Jean Louise Finch (Scout), who a six-year-old who lives with her older brother Jeremy their widowed father Atticus. The following excerpt was taken from the Chapter 12:
