⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.

(Note: This page covers Chapter Twenty-one, told from Jonah's point of view.)

Summary

By Sunday evening, Jonah has missed his ferry back to Hyannis, so the group—Archer, Jonah, Milly, and Aubrey—settles into an unexpectedly normal cookout at Archer's house. Archer grills burgers he found in the gardening shed, and Efram brings Milly and Aubrey over in the resort Jeep after Carson Fine confiscates the keys. Efram declines Archer's invitation to stay, calling it a family thing, but helps arrange chairs before leaving. Milly is still not speaking to Jonah, though her posture seems slightly less cold.

Oona arrives with a foil-wrapped pan of food and greets the girls warmly, expressing sympathy for how they were treated at the gala. She then turns to the autopsy report that Archer received from Dr. Baxter. Aubrey recounts that Mildred (Mrs. Ryan) had a strange reaction when asked about Kayla's death—more alarmed than surprised—but spilled coffee before she could answer. Oona notices a discrepancy: the report lists lorazepam, a sedative, in Kayla's system, but that detail is absent from the family's copy of the report. Milly suggests someone might have drugged Kayla and that Dr. Baxter covered it up, recalling his admission of a “grave injustice.”

Archer remembers that Anders was devastated by Kayla's death, even though she had just dumped him again. Oona recalls that Kayla returned from visiting Anders at Harvard that Thanksgiving, upset, and said she needed to talk to Mrs. Ryan. Milly is shocked to learn that Mrs. Ryan had a son, Matt, who died the year before Kayla. Archer explains that Matt drowned at Cutty Beach during a stormy party where everyone had been drinking. Aubrey reacts with a choking noise, revealing that her father wrote about that beach and that her mother said he never liked the place. Archer recounts the traumatic night: no one realized Matt was missing until too late, and his body wasn't found until the next day. Oona grows pale and expresses guilt, saying she felt responsible for Kayla's death because she got angry instead of helping. Archer tries to comfort her, but Oona's final line suggests she still carries that weight.

Character Development

Jonah remains an observer, feeling guilt over the gala incident and trying to gauge Milly's mood. His narration shows a growing awareness of the family's tangled history, but he stays on the periphery, absorbing information rather than driving the investigation.

Archer emerges as a caretaker—grilling food, comforting Oona, and trying to keep the conversation from spiraling. His recollection of Matt's death is vivid and painful, revealing that he carries trauma from that night as well. He also shows compassion toward Oona, insisting she couldn't have stopped Kayla's drinking.

Milly shifts from cold silence to active theorizing. Her suggestion that Kayla was drugged and covered up shows her sharp, investigative mind, and her shock at learning about Matt Ryan indicates she's piecing together a larger puzzle.

Aubrey has a visceral reaction to the mention of Cutty Beach, linking her father's writing to the tragedy. This moment deepens her connection to the story and hints that her father may have known more than he revealed.

Oona is visibly shaken by the autopsy report and the memory of Kayla's distress. Her guilt is palpable—she admits she got angry instead of helping Kayla, and her trembling hands and pale face show the weight of that regret. Archer's attempt to absolve her doesn't fully land, as her final line suggests she still believes she could have done more.

Themes, Symbols, or Motifs

Hidden Truths and Cover-Ups: The lorazepam discrepancy is the chapter's central revelation, suggesting that someone altered the official record. Dr. Baxter's “grave injustice” comment takes on new meaning, and the idea of a cover-up becomes a driving force.
Guilt and Responsibility: Oona's guilt over Kayla's death mirrors the broader theme of characters blaming themselves for events they couldn't control. Archer's reassurance that “nobody can stop a person who's determined to drink” contrasts with Oona's belief that she should have tried harder.
Interconnected Deaths: The chapter draws a direct line between Matt Ryan's drowning and Kayla's death, both linked to the same circle of friends and the same beach. This motif of repeated tragedy suggests a pattern that may not be coincidental.
Family Secrets: Mildred's alarmed reaction to Kayla's name and the revelation that she had a son who died—a fact Milly didn't know—underscore how much the older generation has hidden from the younger one.
The Beach as a Site of Trauma: Cutty Beach is not just a location but a symbol of unresolved grief and danger, tied to both Matt's death and Aubrey's father's aversion to it.

Why This Chapter Matters

This chapter is a turning point in the investigation. The discovery of lorazepam in Kayla's system—absent from the family's copy—provides concrete evidence of foul play and a potential cover-up. It also connects Kayla's death to Matt Ryan's drowning, suggesting a deeper web of secrets involving the older generation. Aubrey's reaction to Cutty Beach links her father to the tragedy, opening a new line of inquiry. Additionally, Oona's guilt and her memory of Kayla wanting to speak with Mrs. Ryan point toward a crucial conversation that never happened, hinting that Mrs. Ryan may hold key information. The chapter deepens the mystery while also humanizing the characters, showing how the past continues to haunt them.

Study Questions and Answers

What does the lorazepam discrepancy in the autopsy report suggest, and why is it significant?

The discrepancy suggests that Kayla may have been drugged before her death, and that someone—likely Dr. Baxter—altered the official report to hide this fact. This is significant because it transforms Kayla's death from a possible accident or suicide into a potential murder, and it aligns with Dr. Baxter's earlier admission of a “grave injustice.” It also raises questions about who had the power to change the report and why.

How does Aubrey's reaction to the mention of Cutty Beach connect to her father, and what might this imply?

Aubrey chokes when she hears the beach's name, and she reveals that her father wrote about it and that her mother said he never liked the place. This implies that her father has a personal connection to Matt Ryan's drowning—perhaps he was present that night or knows more about what happened. His aversion to the beach suggests unresolved trauma or guilt, making him a potential witness or even a suspect in the larger mystery.

What does Oona's guilt reveal about her character and her relationship with Kayla?

Oona's guilt reveals that she cared deeply for Kayla but feels she failed her by reacting with anger instead of support. She admits she knew Kayla was struggling but didn't help, and she has carried that regret for years. This shows Oona as a compassionate but flawed person, and it also highlights the theme of missed opportunities—had she listened to Kayla, she might have learned what Kayla needed to tell Mrs. Ryan. Her guilt also makes her a sympathetic figure, even as she becomes more entangled in the mystery.
