The Ending in Brief: What Actually Happens

The novel's climax unfolds in two violent set pieces. First, at Kai's wedding, Matthew DuPont—the professor who has been stalking Maya and threatening her family—is confronted by Maya's husband Nate, who punches him. That night, Matthew is murdered. Maya becomes the prime suspect after her phone, footprints, and husband's car are found at the scene.

The second set piece occurs when Maya, drugged by her longtime friend Cecily St. Clair, wakes in a remote cabin. Cecily reveals she has been Matthew's lover for a decade and that she helped him cover up Lila Jones's death years earlier. She intends to burn the cabin with Maya inside, framing her for Matthew's murder. Maya escapes through a window after Marta—the housekeeper who had been threatened by Matthew—knocks Cecily unconscious with a shovel.

Cecily's body is later found burned on her family's property, and the police believe she died in the fire she set. But the real resolution comes three weeks later: Maya scatters Naomi's ashes in the ocean and receives a text from Margaret St. Clair—Naomi's guardian—that reads, “We did it ;).” Maya realizes Margaret killed Matthew, and she thanks her, suppressing her questions.

Resolved and Unresolved Threads

Resolved:

Who killed Naomi? The novel strongly implies Matthew DuPont killed her, though it's never explicitly confirmed on the page. His alibi collapses, and he had motive—Naomi was investigating his crimes.
Who killed Lila Jones? The video shows Matthew and Cecily dragging her body, confirming their role in her death, which had been ruled an accident.
What happened to Greystone? The society's crimes are exposed through Amy's article and Daisy's leaked video, leading to public fallout.
Maya's guilt: She acknowledges her silence and complicity, but the ending suggests she's learning to live with it.

Unresolved:

Margaret's exact method of killing Matthew is never shown. Maya suppresses her questions, leaving the details ambiguous.
The fate of Greystone itself—whether it's disbanded or simply rebrands—is left open.
Maya's legal exposure for her past involvement in the drug scheme and cover-up is never addressed.

How the Themes Land

The ending drives home the novel's central themes:

The corrupting influence of elite secret societies: Greystone's power to silence victims and protect its members is broken only by external leaks and a vigilante act.
The burden of guilt and silence: Maya's guilt over her role in Lila's death and her failure to warn Naomi is a weight she carries into the final pages.
The protective bond between sisters: Maya's determination to uncover the truth about Naomi's death is the engine of the plot, and her final act of scattering ashes is a release.
The outsider's struggle for belonging: Maya's initial desire to join Greystone—despite her misgivings—mirrors her lifelong search for acceptance.
Justice versus self-preservation: Maya chooses to thank Margaret for killing Matthew, a morally ambiguous act that prioritizes personal closure over legal justice.

The Author's Note and What It Adds

The book closes with an author's note, not an epilogue. Lauren Ling Brown clarifies that Greystone and Sterling Club are fictional, and she explains her personal inspiration: growing up multiracial and feeling like an outsider. She notes that the story explores how a small corrupt organization can contaminate a well-intentioned one. This note reframes the ending as a cautionary tale about privilege and complicity, rather than a simple thriller resolution.

Reasonable Interpretations

Margaret as a vigilante: Her killing of Matthew is presented as a protective act—she was Naomi's guardian and had warned Matthew to stay away. Maya's gratitude suggests she sees it as justice, not murder.
Maya's moral compromise: By thanking Margaret, Maya implicitly endorses extrajudicial violence. The novel doesn't condemn her, leaving readers to judge.
Cecily as a tragic figure: She loved Matthew and was manipulated by him, but her willingness to kill Maya shows she was complicit, not merely a victim.
The fire as symbolic: Cecily's death by fire—the same method she used to try to kill Maya—suggests poetic justice, though the novel never explicitly frames it that way.

Reader Questions and Answers

1. Did Matthew kill Naomi?

The novel strongly implies it. His alibi for the time of Naomi's death collapses, and he had motive—Naomi was investigating his crimes. However, the text never shows the act itself, so it remains an implication rather than a confirmed fact.

2. Why did Cecily help Matthew cover up Lila's death?

Cecily was in love with Matthew and had been having an affair with him since college. She tells Maya, “Matthew has meant everything to me for the past ten years.” Her loyalty to him outweighed any moral qualms.

3. What happened to Lila Jones?

Lila was a Greystone member who planned to expose the society's crimes. She was killed during a ski trip, and the video shows Matthew and Cecily dragging her body, confirming their involvement. Her death was originally ruled an accident.

4. Why didn't Maya go to the police earlier?

Maya was complicit in covering up Lila's assault and death—she had helped drug Matthew and had accepted money from Greystone. She feared exposure and prison, so she stayed silent for years.

5. Is there an epilogue?

No. The book ends with an author's note, not a traditional epilogue. The final chapter (Chapter 69) serves as the resolution, with Maya scattering ashes and receiving Margaret's text.

6. What does the epigraph about secret societies mean?

The epigraph quotes a trustee who says secret societies will inevitably be used for evil. This sets up the novel's central critique of Greystone and its corrupting influence, which the ending confirms.
