From a command center in a library parking lot, Nolan coordinates the search for the missing Peter Evanston, Arthur’s latest victim, deliberately sending most volunteers to areas he knows are irrelevant. His primary concern is that Sheriff Yates will expand the search to one of Arthur’s other burial grounds, potentially exposing Harper. Harper arrives at the command center, explaining that her absence would raise suspicion, especially since Nolan is leading the operation.
Nolan confronts her with a photo posted on the Sleuthseekers Discord server, warning that the group is trying to identify her from an image Sam Porter took of her walking away from their argument in a local shop called Maya’s Magical Mixtures, her back to the camera. Sheriff Yates interrupts them, adding two more missing men to the search: Sean McMillan, a tourist, and Jake Hornell, a local. Yates questions Harper about her acquaintance with Hornell, revealing he has Sam’s drone footage of them talking. The search is complicated when Evanston’s widow, Mrs. Evanston, arrives with her dog, Queenie, who shows a surprising and immediate affection for Harper. Before leaving, Yates quietly asks Nolan and Harper if they’ve heard of another man, Bryce Mahoney. Harper says no, but Nolan can tell she’s lying. When Harper again insists on joining the search, Nolan pleads with her to confide in him, but she walks away, leaving him in the dark.
Harper joins a search party at the Lancaster Distillery, the business owned by Arthur’s family. She secretly plans to visit the old grain shed, Arthur’s first burial ground. She is met by Lukas Lancaster, who informs her he has scheduled a tour of a memory care facility for Arthur. As the search begins, Harper slips away to the grain shed. Inside, she climbs the ladder and hides Arthur’s “murder bag”—containing a book about poisons, gravesites, and everyone he’s killed—and Peter Evanston’s clothes in the loft, stuffing them into a hollow between the rafters and the boards lining the roof. She also discovers a Farmer’s Almanac containing a cryptic handwritten note about a sunny landscape.
Her task is interrupted when she overhears Lukas talking with Maxine Yates, the sheriff’s daughter and Lukas’s unrequited childhood love. Maxine reveals she now works for the company developing the land Arthur used to own by the Ballantyne River. Harper tries to act as a wingman for the socially awkward Lukas, but her efforts fail. Later that evening, Harper returns to her cottage and is disturbed to find that the black knight on her chessboard sits in a new position.
Nolan begins journaling notes about Harper, hoping to better understand her. He arrives at Harper’s cottage, and she immediately asks if he moved the chess piece. He admits he did, which assuages her fear. When Nolan asks about Bryce Mahoney, Harper confirms that the human tibia she was carrying in a bag when they first met belonged to him and is now stored in her freezer. Their tense conversation turns into an aggressive, flirtatious encounter.
Harper agrees to perform oral sex on Nolan if he tells her the story of his first kill. As part of a BDSM scene, Nolan binds her wrists with his belt. Amid this, he confesses his true first murder was not Marc Beaumont. He killed Marcus Urkhart, a teenager who had viciously bullied Nolan’s younger brother, Billy, whom Nolan deduced—based on circumstantial evidence—was responsible for a brutal attack that left Billy in a coma. To cover the killing, Nolan broke into the apartment of a registered sex offender, Clinton Taff, stole evidence, and planted it at the scene of Marcus’s death to frame Taff for the murder. After his confession and their sexual encounter, Harper fully accepts his violent past, calling him a villain and telling him she prefers him that way.
In bed with Harper, Nolan scrolls through the Sleuthseekers Discord and sees a user named KnightofTruth post the photo of Harper again, determined to learn her identity. The next morning, he urges her to tell him about her past so they can preemptively counter the Sleuthseekers. He gives her a silver bracelet engraved with “A²BC,” which belonged to her or her boyfriend, Adam. The object causes Harper to break down.
She confesses her deep guilt over Adam’s death. She explains that while they were held captive by a serial killer named Harvey Mead, she pounded on their cellar door to get help for her feverish boyfriend. Instead of help, the noise attracted Mead, who took Adam upstairs and killed him with a chainsaw. Harper believes that if she had waited, they would have been rescued within the hour—though Nolan privately questions her account, wondering who would have come and whether the story she told the police was complete. Arthur interrupts before Nolan can press further. Harper tells Nolan she is afraid to love him for fear of losing him. Nolan reassures her by revealing he has extended his stay in Cape Carnage.
On a future date, August 26th, Sheriff Yates stands alone inside Harper’s cottage. He knows her real name is Autumn Bower, a secret he credits to Sam and Vinny’s investigative work. He reflects on murdering Arthur Lancaster’s daughter, Poppy, nearly 30 years ago, confirming that he is the serial killer La Plume, whom Arthur sought in vain for years. He views Nolan as the last remaining mystery surrounding Harper, believing the layers must be surgically peeled away to force her transformation. Before leaving, he takes the black knight from the b8 square of the chessboard and puts it in his pocket, revealing he has been secretly entering her home and moving the pieces.
Harper and Arthur critique his new garden topiary, which unfortunately resembles a pair of penises. The conversation turns serious, and Harper asks him about his late wife, Vivian. In a moment of lucidity, Arthur tells her that the love they shared was worth all the subsequent grief, encouraging her to embrace love despite the risk of loss.
Later, Harper goes into town and enters Maya’s shop, where she encounters three members of the Sleuthseekers: Emma, Charlie, and Tylor. Hiding her face and trapped in a narrow aisle between the group, she overhears them discussing their investigation into Sam and Vinny’s deaths. Emma shows Maya the photo of Harper from the Discord server, but Maya feigns ignorance. After the group leaves, Maya tells Harper she will always protect locals from outsiders. She also confesses that Jake Hornell used to peep through her window and that she is glad he is missing. Feeling a new sense of belonging and solidarity, Harper tears down Jake Hornell’s missing person poster on her way home.
At the command center, Sheriff Yates notices the fresh knife cut on Nolan’s neck; Nolan dismisses it as a shaving accident, though Harper left it. He later returns to the cottage and finds that Harper has cut her hair into a short bob to disguise her appearance from the Sleuthseekers. He helps her even out the haircut, and they share an intimate, romantic evening. The next morning, before she wakes, Nolan finds a broken men’s watch in her dresser engraved with “To adventure,” which he assumes belonged to her boyfriend, Adam.
Determined to protect her, Nolan drives to the Capeside Inn. He slips behind the front desk and checks the guest registry, confirming that the three Sleuthseekers—Emma, Charlie, and Tylor—are staying in the room adjacent to his. He hides when Emma and Charlie walk through the lobby, identifiable by the Sleuthseeker patches on their backpacks. They discuss Tylor, who isn’t with them. Outside, he sees Carlie standing alone at the edge of the cliff, taking photos of the sunrise. Without hesitation, Nolan sprints toward him and tackles him, sending them both plunging into the ocean below. He holds the man underwater until he drowns, fully committing to killing anyone who poses a threat to Harper.
During a BDSM scene, Nolan confesses to Harper that his first murder was not Marc Beaumont—which he’d previously told her—but Marcus Urkhart, a teenager he killed for brutally attacking his younger brother. This confession begins a slow process of emotional vulnerability and emotional connection that elevates their partnership beyond a shared capacity for violence. His crimes are comparable to hers, but more importantly to Harper in this scene, the reasons behind them are what bond them. By revealing he methodically framed a registered sex offender for the crime, Nolan establishes a parallel between his own vigilantism and Harper’s. His actions are calculated, motivated by a personal code of justice. This act explores The Failures of the Justice System, suggesting that when legal channels are insufficient to punish people who have done harm, individuals may create their own moral frameworks. Harper does not fear or judge him but rather accepts him, reinforcing that his true nature won’t drive her away. She embraces him as a “villain” and declares she “wouldn’t want [him] any other way” (107). They see in each other a reflection of their own darkness, finding validation in their behavior. Nolan thinks on how the satisfaction of killing Marcus blends with the pleasure of sexual activity, symbolizing the deep attachment he and Harper have to violence as well as the relief of vulnerability with another person.
The arrival of three Sleuthseekers—Emma, Charlie, and Tylor—in Cape Carnage injects a new layer of external threat, directly engaging with The Human Cost of True Crime Content. Overheard in Maya’s shop, their conversation reveals a detachment from the gravity of the murders they are investigating; they discuss the deaths of Sam and Vinny in the context of taking holiday time and make plans for karaoke night. This behavior mirrors the real-world phenomenon of individuals treating real-life tragedies as a form of entertainment or morbid tourism. The conflict between the locals and these outsiders is sharpened when Maya lies to protect Harper from the group’s inquiries. Maya’s assertion that “we look after our own” and her confession of relief over Jake Hornell’s disappearance signal a significant shift for Harper (143). No longer an isolated killer, she is accepted as part of a community with its own code of loyalty. Harper’s subsequent act of tearing down Hornell’s missing person poster is a gesture of defiance and solidarity, a public claim of her place within Cape Carnage’s unique moral ecosystem.
Harper’s sudden breakdown after Nolan returns Adam’s bracelet exposes the trauma that underpins her violent identity. Her confession of guilt over Adam’s death at the hands of Harvey Mead reveals the deep psychological wounds she has carried since her escape. Her repeated belief that “It was my fault” for attracting the killer’s attention exposes the core of her self-blame (124), a key component of The Cyclical Nature of Trauma. This vulnerability contrasts with her usual guarded demeanor, showing that her murderous persona is a shield built around an unhealed injury. The subsequent, impulsive decision to cut her hair is a physical manifestation of her desire to shed her past and control her present identity. It is both an act of disguise to evade the Sleuthseekers and a symbolic attempt to sever herself from the long-haired girl who was once a victim. This moment, coupled with her admission that she is “afraid to love” Nolan for fear of loss (127), crystallizes the central internal conflict of her character: the struggle between her need for self-preservation through isolation and her burgeoning desire for connection.
The interlude chapter structurally reframes the narrative by including chapters from the perspective of Sheriff Yates, exploring his hidden identity as La Plume, the true antagonist. His solitary presence in Harper’s cottage confirms he is the one who has been secretly entering her home, an act of physical and psychological violation. His monologue, in which he recalls murdering Poppy Lancaster and coolly observes Harper, dismantles the pretense of a bumbling small-town cop and exposes him as a manipulative predator. This reveal recontextualizes the motif of the chessboard. What Harper feared was a sign of her own deteriorating mental state—“I thought I was going crazy” (103)—is in fact a calculated move in Yates’s psychological game. By stealing the black knight, Yates asserts his control over her environment and her sanity, treating her as a piece in his own deadly strategy. His view of her as a “chrysalis” whose layers he must “surgically peel” away emphasizes his god complex and his desire for power over others (129). The scene adds a new layer to novel’s exploration of The Failures of the Justice System, cementing the novel’s cynical view that true safety cannot be found in established institutions.
