When word spreads that Tom Robinson has been shot while trying to escape from prison, Jem struggles to come to terms with the injustice of the trial and of Tom Robinson’s fate. After making a variety of threats against Atticus and others connected with the trial, Bob Ewell assaults Scout and Jem as they walk home one night, but Boo Radley saves the children and fatally stabs Ewell. The sheriff, knowing that Boo, like Tom Robinson, would be misunderstood and likely convicted in a trial, protects Boo by saying that Ewell tripped and fell on his own knife. After sitting and talking with Scout briefly, Boo retreats into his house, and Scout never sees him again.
