What happens in Chapter 4 of To Kill a Mockingbird?
Chapter 4 begins with Scout feeling increasingly disillusioned with school — Miss Caroline's strict teaching methods feel suffocating after a summer spent reading freely with Atticus. One afternoon on her way home, Scout notices something shiny in the knothole of the large oak tree on the Radley property. She reaches in and pulls out two pieces of chewing gum wrapped in foil. Despite Jem's warnings, she chews them and feels fine afterward. Later, she and Jem find a small box in the same knothole that contains two old "Indian-head" pennies — considered lucky coins by local tradition. The children decide to keep the pennies, unsure of who left them. The chapter wraps up with the arrival of summer and Dill's return. The three friends dive into dramatic play, ultimately deciding to act out the story of Boo Radley. During one intense game of "Boo Radley," Scout gets rolled inside a tire that crashes into the Radley front steps. Dazed and shaken, she quickly scrambles away — but not before she thinks she hears laughter from inside the house. Jem fetches the tire, and when Atticus asks what they're playing, the children evade the question, simply saying "just a game."
Analysis
Chapter 4 is where Harper Lee subtly introduces the novel's core themes of gift and mystery. The knothole acts as a threshold — a gap between the familiar world of Maycomb and the mysterious interior of the Radley house. Lee demonstrates her skill in restraint: she never reveals who left the gum or the pennies, allowing the reader to infer much more than Scout does. The tone is intentionally childlike on the surface, but the chapter serves an important structural purpose, planting the seeds for the motif of unseen kindness that will resonate later.
The tire episode shifts the tone dramatically. What starts as carefree summer fun quickly turns unsettling when Scout hears laughter coming from the Radley house. Lee expertly uses Scout's first-person perspective: the laughter is described matter-of-factly, without any dramatic flair, making it feel more eerie than any elaborate Gothic description could. The children's Boo Radley antics add a layer of meta-theatricality — they are acting out a story they only partly believe, blending fear and play until the distinction between the two blurs.
Atticus's brief appearance at the chapter's end is significant. His gentle question about the game isn’t probing, but the children's avoidance shows that childhood myths are already operating beyond adult control. Lee introduces the first hint of the children's moral development not through Atticus's well-known speeches but through a simple, instinctive lie — a clever choice that trusts the reader to catch what the narrator is not yet ready to express.
Key quotes from Chapter 4

Scout's instinctive second-guessing after chewing the Radley knothole gum — a small moment that captures her oscillation between curiosity and the fear Maycomb has taught her.
“Jem said the Indian-heads were real lucky. He said so because they were so old; 1906 was on one of them.”
The children assign talismanic value to the pennies, revealing how Maycomb's folk superstitions shape even the most rational of the Finch children.
“Someone inside the house was laughing.”
Scout's flat, unadorned report after the tire rolls her onto the Radley porch — the chapter's most quietly chilling line, delivered without commentary.
