作者Harper Lee。于2016年2月过世。 知道这本书其实源于当时作者只写过这一本书，就享誉全球，很另我好奇。不过后来在2015年，她又出了第二本，也是最后一本。 

The characters were basically based on her observation of her own family and neighbors. Especially an event was occurred near her hometown in 1936, when she was 10 years old. 

The book was very serious about issues of rape and racial inequality, and the destruction of innocence during that time.

The story took place during three years between 1933 - 1935 of the Great Depression, at Maycomb, Alabama. A six-year-old girl, Jean Louise Finch (Scout), lived with her older brother, Jem, and their widowed father, Atticus Finch. He was a middle-aged lawyer who had lost his wife when Scour was about 2 years old.

The book started with their neighbor, the Radley family, especially one Radley boy.  There are rumors about his appearance and reasons for remaining hidden. Three kids are fascinated by, and terrified of their neighbor, the Radley. They would like to get him out of his house. But later on they found that someone left them small gifts in a tree outside the Radley place. Still no appears in person. 

Their father Atticus was appointed to defend for Tom Robinson, who had been accused of raping a young white woman, Mayella Ewell. Due to the inequality between the black people and white people, Maycomb's people disapprove Atticus's action and many kids taunt Jem and Scout because of this. Although there were no evidence showed that Robinson raped the young white woman, but the jury convicts him just because he was a black man. The white people cannot let black people won.

Bob Ewell won, but he felt that he was humiliated during the trial. He vowed revenge, by spitting in Atticus' face, trying to break into the judge's house, menacing Tom Robinson's widow. Finally, he attacks Jem and Scout when they walked back from school on a dark night. Turns out, the Radley boy rescued them and Bob Ewell was died. At the end Sheriff Tate convinced Atticus that Bob Ewell fell on his own knife.
