The climax of the novel undoubtedly comes during the attack on the children by Bob Ewell as they return from the Halloween pageant in Chapter 28. Not only is it the greatest point of dramatic tension and rising action in the novel, where the innocent Jem and Scout are targeted for murder by the evil Ewell, but it also serves several other purposes. It allows the novel's unseen "phantom," Boo Radley, to finally appear for the first time--and in true heroic fashion. It also serves to tie together the two main parts of the novel: The children's fascination with Boo in the early chapters of Part One; and the deserved end received by Bob--the instigator of the false charges of rape that result in the trial of Tom Robinson, the major focus of Part Two of TKAM. It also reveals how Jem received his elbow injury and how "the Ewells started it all," allusions made by the narrator on the first page of the novel but left unanswered until that fateful Halloween night.
