Summary

Stella Hudson drives away from the Barclay house, still rattled by the darkness she felt inside. As she approaches the gate, an incoming call lights up her Jeep’s console. The caller ID shows it’s from Rollingwood Primary School, the private school Rose attends. Stella has been trying to reach Rose’s teacher all week, so she pulls over by the gate and answers, even though she’s too shaken to concentrate.

The caller is Diane Jackson, the principal of Rollingwood. Stella begins to explain her role in the case, but the principal cuts her off. Jackson tells Stella that Rose “was” a student at Rollingwood—and that she will not be returning. Stella is confused, because both Ian and Beth told her the homeschooling was temporary. The principal clarifies that Rose was not withdrawn by her parents; she was asked to leave. Stella presses for the reason, and Jackson explains that any student bringing a weapon to school faces immediate expulsion. Rose brought a knife to school, and her teacher found it in her backpack. The principal ends the call, suggesting Stella contact Rose’s former school for more information.

Stella sits in her car, stunned. She thinks back to the many ways the Barclay family has kept her away from Rose: Beth ushering her out of the plastic house during their first meeting, Ian’s grim expression when she studied the vegetable gardens, the negotiation required just to take Rose to Lucille’s, and Harriet’s reluctance to let Stella anywhere near Rose’s bedroom. The pieces begin to fit together. This shattered, battling family is united when it comes to the little girl who is obsessed with weapons and hides a book about a sadistic serial killer beneath her pink comforter. They are closing ranks around Rose.

Character Development

Diane Jackson – The principal is a minor but pivotal character. She is professional and firm, unwilling to share more than necessary, but her revelation shatters Stella’s assumptions.

Ian and Beth – Though not present in the scene, their deception is exposed. Stella realizes they conspired to hide Rose’s expulsion, just as Ian had previously colluded with Tina. Their united front, despite their bitter divorce, reveals how far they will go to protect Rose—or to protect themselves.

Harriet – Stella recalls Harriet’s initial warmth but also her refusal to let Stella near Rose’s bedroom. This memory now takes on a darker meaning, suggesting Harriet is part of the family’s effort to keep secrets hidden.

Themes, Symbols, or Motifs

Weapon obsession – The knife Rose brought to school is a concrete symbol of the danger lurking beneath the family’s polished surface. It connects to Rose’s fascination with weapons and the serial killer book hidden under her comforter.

Parental deception – Ian and Beth’s lie about Rose’s schooling is another layer of the web they’ve woven. Stella realizes they are willing to deceive her, and each other, to control the narrative.

Family closing ranks – The chapter’s central motif. Despite their conflicts, the Barclays unite to keep Stella away from Rose, revealing a protective—and potentially sinister—instinct.

Surveillance – Stella’s awareness of the gate camera and her instinct to lock her doors highlight the atmosphere of watchfulness and paranoia that surrounds the family.

Hidden secrets – The expulsion is just one secret; Stella senses there are more. The chapter reinforces the idea that the truth is buried beneath layers of lies.

Uncovering truth – Stella’s role as a fact-finder is pushed forward. The principal’s call gives her a concrete lead, but also raises new questions about Rose’s past and the family’s motives.

Why This Chapter Matters

This chapter is a critical turning point in the novel. Stella’s discovery that Rose was expelled for bringing a knife to school shatters the family’s carefully constructed story. It explains why Ian and Beth were so reluctant to let Stella spend time alone with Rose, and why Harriet guarded Rose’s bedroom. The revelation also deepens the mystery: why would a nine-year-old bring a knife to school, and what does it have to do with Tina’s death? Stella’s realization that the family is closing ranks around Rose sets the stage for her to dig deeper, even as the danger around her intensifies.
