Why has Harper Lee separated To Kill a Mockingbird into two parts?Plese explain in detail.
There are two main plots that dominate the novel To Kill a Mockingbird: The children's fascination with the mysterious Boo Radley, which dominates Part One (Chapters 1-11); and the trial of Tom Robinson, which covers most of the first 15 chapters of Part Two. It seems a logical structural form, creating a break between the two primary story lines. Additionally, Part Two (Chapter 12) opens with Scout's description of Jem's growing pains; he is approaching puberty, and the age difference between the still childish Scout and the nearly teenage Jem becomes more obvious. The final portion of the novel (Chapters 28-31) ties together the two plots: Boo Radley finally makes his appearance when he tangles with Bob Ewell, Tom Robinson's accuser.
