What happens in Chapter 15 of To Kill a Mockingbird?
The night before Tom Robinson's trial, Atticus drives to the Maycomb jail to stand guard outside Tom's cell, expecting trouble. Scout, Jem, and Dill secretly follow him and watch from the shadows as a convoy of cars arrives, and a mob of men—many from the Old Sarum community—demands that Atticus hand Tom over. Tension builds until Scout, unable to restrain herself, breaks from the darkness and rushes to her father. Jem and Dill quickly follow her. Atticus tells them to go home, but Jem stands his ground. Scout, unaware of the full danger, spots Walter Cunningham Sr. in the crowd and starts chatting with him about his entailment and his son, who is in her class. Her innocent, one-sided conversation gradually diffuses the mob's threat. Cunningham, embarrassed into recognizing himself as an individual rather than just part of the crowd, tells Scout to say hello to Walter Jr. and then instructs the men to break up. The cars drive away. Mr. Underwood, who has been watching from his window above the Maycomb Tribune office with a double-barrel shotgun, calls down to Atticus that he had him covered the whole time. The family walks home, the crisis quietly resolved.
Analysis
Chapter 15 is the most action-packed moment in the novel before the trial, and Lee builds it with a careful use of dramatic irony: the reader knows the deadly stakes that Scout doesn’t. This gap drives the chapter forward. Scout's narration stays grounded—she notices faces, recognizes a hat, recalls a conversation about entailments—and it’s this refusal to abstract that disarms the mob. Lee makes a sharp point about collective violence: anonymity fuels it, while individuality dissolves it. The moment Scout names Walter Cunningham, linking him to his son, his role as a father, and a specific legal issue, the mob mentality begins to break apart.
Lee's skill shines in her tone management. The chapter starts with the domestic comedy of Maycomb gossip—Heck Tate's visit, the men on the front lawn—before shifting into real menace when night falls at the jail. The change is marked not by melodrama but by Atticus's actions: he folds his newspaper slowly, sets his book aside, and stands. These small gestures carry immense significance.
Mr. Underwood's silent watch from above the street mirrors Atticus's own vigilance, and his revelation at the end of the chapter subtly reframes what we believed we witnessed: the children were never as vulnerable as they thought. The mockingbird motif hovers over Tom's cell, the innocent man safeguarded—just barely—by the thinnest layer of human decency that Scout inadvertently restores.
Key quotes from Chapter 15
“'Hey, Mr. Cunningham. How's your entailment gettin' along?' … I began to feel the remoteness of it all: I was talking to a man I didn't know, in a language I didn't understand, about something I didn't care about.”
Scout addresses Walter Cunningham Sr. directly in the middle of the mob, her social instinct overriding her fear and inadvertently humanising him before the crowd.
“'So it took an eight-year-old child to bring 'em to their senses, didn't it?' said Atticus. 'That proves something—that a gang of wild animals can be stopped, simply because they're still human.'”
Atticus reflects on the night's events with Jem and Scout afterward, articulating the chapter's central moral without sentimentality.
“'I was sittin' up there with a double-barrelled shotgun,' he said. 'Didn't you know I had you covered all the time, Atticus?'”
Mr. Underwood calls down from his window above the Tribune office once the mob has dispersed, revealing his silent, armed watch over Atticus and the children.
