Summary

The chapter opens in the dark living room, where Wyatt's phone screen illuminates his face. He tells Courtney he knows where Reese is. Using Snapchat's Snap Map feature, he shows her an avatar of Reese that places her only five minutes away. Courtney is unsettled to learn that anyone can see a person's real-time location through the app, though Wyatt explains that users can opt into ghost mode to hide their whereabouts.

Courtney immediately calls Detective Evans, waking him in the early morning hours. She shares the Snap Map screenshot, but Evans tempers her excitement with caution. He explains that Snapchat maps are only as accurate as the last login time and that someone else might have accessed Reese's account. Despite his reservations, he agrees to investigate.

Courtney wakes hours later, disoriented and devastated anew by the reality of Emily and Nolan's deaths. Her phone slides off her chest; she had fallen asleep waiting for Evans to call. When he finally does, he reports the overnight search found nothing. The police now plan a ground search using community volunteers. Courtney resolves to join, leaving Elliott to watch the three children.

Before departing, Courtney notices an unusual number of boats on the lake. She assumes they are fishing until Elliott points out the truth: they are spectators hoping to glimpse the crime scene, snapping photos with morbid hashtags like #crimescene and #murderhouse. Courtney's rage simmers as she remembers how Emily cherished her peaceful mornings on the deck overlooking the lake.

Elliott tries to dissuade her from joining the search, then hesitantly brings up Reese's words to Emily the night of the deaths: "I hate you. I wish you'd die." He implies Reese might have killed her parents and fled. Courtney vehemently rejects this, but privately acknowledges the cheerful child who once played hide-and-seek in her closet has become a defiant, almost unrecognizable teenager. Elliott backpedals, but Courtney sees he remains unconvinced.

Outside, the police officer assigned to the cottage questions Courtney's departure. She asserts her right to leave and heads to her car, feeling watched as she scans the surrounding woods for unseen eyes.

Key Events

Wyatt reveals Reese's location: Using Snapchat's Snap Map, Wyatt pinpoints Reese's avatar and determines she is only five minutes away from the cottage.
Courtney alerts Detective Evans: She calls him in the middle of the night with the Snap Map evidence, but he warns the map may not show Reese's current location or that someone else may have logged into her account.
Police conduct an overnight search: Detective Evans's initial search yields no results, prompting a larger ground search with community volunteers the following morning.
Courtney decides to join the search: Over Elliott's objections and despite the officer's implied reluctance, she insists on participating in the ground search.
Voyeurism on the lake is exposed: Courtney realizes the boats on the lake belong to spectators rubbernecking at the crime scene and posting about it on social media.
Elliott voices suspicion about Reese: He reminds Courtney of Reese's angry outburst at Emily and suggests Reese might be responsible for the deaths and her own disappearance.
Courtney grapples with her changed perception of Reese: She reflects on the contrast between the affectionate child she once knew and the defiant teenager Reese has become.

Character Development

Courtney demonstrates fierce loyalty and proactive determination in this chapter. She does not hesitate to act on Wyatt's lead, pushing past her exhaustion and grief to advocate for her niece. Yet her confidence is tested when Elliott raises the possibility of Reese's guilt. Courtney's internal admission that the "new Reese" is almost a stranger reveals an unsettling doubt beneath her outward defense. Her defiance of both Elliott and the police officer signals a shift toward independent action, even as her fear of being watched underscores her vulnerability.

Elliott emerges as a cautious, perhaps suspicious counterweight to Courtney. His reluctance to join the search and his pointed recollection of Reese's words to Emily suggest he harbors theories he is reluctant to voice fully. His quick concession that Reese "didn't do it" rings hollow, and his inability to meet Courtney's eyes betrays his true thoughts. This tension between the spouses adds strain to an already fractured family dynamic.

Detective Evans proves methodical and protective rather than reactive. His knowledge of Snapchat's limitations prevents a premature, potentially dangerous operation. His insistence that Courtney remain at the cottage—both to care for the children and for her own safety—positions him as a competent, if somewhat paternalistic, authority figure.

Reese remains offstage, but the chapter complicates her portrayal. Wyatt's Snapchat evidence suggests she may be alive and nearby, while Elliott's pointed reminder of her final words to Emily plants the idea that she could be a suspect rather than a victim. Courtney's memory of young Reese playing hide-and-seek—so clever she was "hidden in plain sight"—acquires new, darker resonance.

Themes, Symbols, or Motifs

Technology and the Illusion of Certainty: The Snap Map initially seems like a miraculous solution, offering precise, real-time location data. Detective Evans quickly dismantles this illusion, explaining its unreliability. The chapter highlights the gap between the digital representation of a person and their actual circumstances—a miniature avatar cannot convey danger, coercion, or whether the account holder is even alive.

Hidden in Plain Sight: Courtney's memory of young Reese hiding in her closet, fully dressed in Courtney's clothes, becomes a powerful motif. As a child, Reese's ability to vanish while remaining close mirrored her cleverness. Now, the phrase takes on ominous connotations: Reese may be hiding deliberately, or someone may be concealing evidence in plain view. The boats on the lake, disguised as ordinary fishermen, embody this same dynamic—something sinister masquerading as the mundane.

Voyeurism and Exploitation of Tragedy: The spectators on the lake, photographing the cottage for social media with callous hashtags, represent the invasive public gaze that descends on private suffering. Emily's cherished view of the lake, once a source of solitude and peace, has been corrupted into a vulnerability that strangers exploit for entertainment. This motif reinforces the theme of exposure and the loss of safe spaces.

Doubt and Familial Trust: The chapter directly confronts the possibility of Reese's guilt. Elliott's suspicion and Courtney's defensive reaction expose a fracture in how family members process grief and fear. The question of whether they truly know Reese echoes the larger mystery of the novel: how well can anyone know another person, especially a teenager in crisis?

Why This Chapter Matters

Chapter 15 functions as the first actionable lead in the search for Reese, shifting the narrative from passive shock and grief to active investigation. It introduces the Snap Map as both a tool and a potential red herring, keeping readers uncertain about whether Reese is a victim, a runaway, or something else entirely. The chapter also deepens the thematic preoccupation with visibility and concealment: the lake spectators, the police officer's watchful presence, Courtney's sensation of being observed, and the memory of Reese hidden in plain sight all converge to create an atmosphere of pervasive surveillance. Finally, Elliott's expressed doubt about Reese fractures the united front the family has maintained, injecting interpersonal conflict into an already volatile situation.

Study Questions and Answers

Why does Detective Evans caution Courtney about relying on the Snapchat map, and what does his caution reveal about the investigation's approach?

Detective Evans warns that Snapchat maps are only as reliable as the last time a person logged in and that someone else could have accessed Reese's account. This caution reveals the investigation's commitment to verified evidence over easy assumptions. It also underscores a core tension in the novel: the gap between digital traces and physical reality, a gap that can lead investigators—and readers—astray.
How does Elliott's reference to Reese's angry words at Emily complicate the reader's understanding of Reese's disappearance?

By recalling that Reese told Emily "I hate you. I wish you'd die," Elliott introduces the possibility that Reese may have been involved in her parents' deaths rather than being a missing victim. This shifts the narrative lens, forcing readers to consider Reese not only as a vulnerable teen but as a potential suspect, a duality that Courtney struggles to reconcile with her memories of the affectionate child Reese once was.
What is the significance of the boats on the lake and Courtney's realization about them?

The boats initially appear to be fishermen, but Courtney discovers they are spectators gawking at the crime scene and posting photos with hashtags like #crimescene. This moment underscores the theme of voyeurism and the public's appetite for tragedy as entertainment. It also highlights the erosion of privacy for the grieving family, as Emily's once-peaceful view of the lake has been weaponized by strangers seeking morbid content for social media.
