Plot Summary

In the coastal town of Cape Carnage, Maine, Harper Starling lives a double life. She tends to the gardens of her elderly mentor, Arthur Lancaster, the owner of a local distillery, the landlord of the cottage she lives in, and a prolific murderer now experiencing early Alzheimer’s disease. A serial killer herself, she learns from Arthur and uses their garden to help dispose of their victims. Her life is further complicated by her relationship with Nolan Rhodes, another killer who came to town seeking revenge on Harper, who he believes killed his brother in a hit-and-run four years prior. They developed a sexual and later romantic attachment to one another.

The story opens with Harper dismembering Arthur’s latest victim, a tourist named Peter Evanston. Nolan confronts her, revealing he has discovered that her true identity is actually Autumn Bower, a woman who escaped the infamous serial killer Harvey Mead after Mead gruesomely murdered her boyfriend. Furious that she let him believe she was his brother’s killer, Nolan admits he almost murdered her. Harper confesses that she was at the scene of his accident but fled, adopting the identity of a drunk driver who died in a separate crash that night to escape her traumatic past and keep a promise of secrecy to Arthur. Nolan informs her that the recent deaths of two amateur investigators, Sam Porter and Vinny Meschino, will draw more of their group, the Sleuthseekers, to Cape Carnage, putting Harper in extreme danger. While Harper killed Sam in the previous book to protect Nolan, she didn’t kill Vinny and is shocked at his death.

The town sheriff, Damian Yates, reveals that he killed Vinny in self-defense after being attacked and believes Vinny was responsible for Sam’s death, temporarily deflecting suspicion from Harper and Nolan. Yates recruits Nolan, a former firefighter and Search and Rescue specialist, to lead the official search for Peter Evanston. This new role allows Nolan to misdirect the search party away from Harper and Arthur’s crimes. The two work together to cover their tracks, exhuming 16 bodies from one of Arthur’s old dumping grounds along the Ballantyne River. Their forced proximity deepens their bond, and Nolan confesses his love for Harper, though he asks her not to reciprocate until he has earned her trust. 

As more Sleuthseekers arrive in town, the threat intensifies. An online user named KnightofTruth posts a photo of Harper, taken from behind, on the group’s Discord server, asking for her identity. Wanting to protect Harper, Nolan drowns one of the Sleuthseekers, Charlie. The pressure mounts when Sheriff Yates adds two more missing men to the search: Sean McMillan, whom Harper killed, and Jake Hornell, whom Nolan killed. Yates reveals he has drone footage of Harper speaking with Jake just before his disappearance. Simultaneously, Harper supports Arthur through the challenges of his Alzheimer’s, navigating his fluctuating memory and impulsivity, while his grandson, Lukas, begins exploring long-term care options, a prospect Harper finds deeply painful. She prepares their garden for an upcoming gardening competition, though Nolan secretly helps her and Arthur ensure their topiary looks good, further gaining her trust.

As their relationship blossoms amidst the chaos, Harper and Nolan move in together. To create a plausible explanation for Jake Hornell’s disappearance, they break into a local watersports shop to retrieve his surfboard and wetsuit. Nolan plants a shattered surfboard fin and a fragment of Jake’s bone, which he had secretly kept, on a nearby beach to stage a fatal shark attack. The evidence is soon discovered, and the case is unofficially closed. When the persistent Sleuthseeker Tylor Knightsbridge, who is KnightofTruth, gets too close to her identity, Harper poisons him with a non-lethal dose of one of Arthur’s poisons during the Taste of Terror festival’s chili-eating contest. The poison causes him to bleed from his eyes and vomit blood, landing him in the hospital. Later, at the secret Murder Mash Barn Dance hosted among locals, Nolan reveals he has decided to leave his life in Tennessee to stay in Cape Carnage for her. Overcome with emotion, Harper confesses that she loves him, and they officially commit to a future together.

Throughout the novel, brief interludes reveal Sheriff Yates breaking into Harper’s home, moving pieces on her chessboard and reflecting on his intention to turn her into a more legendary serial killer like him. This reveals him to be La Plume, the mysterious criminal that murdered Arthur’s daughter Poppy. Arthur looked for him for years, not knowing who he is, but La Plume stayed in Cape Carnage under the false identity of Sheriff Yates to observe Arthur, intrigued by his intense grief. Preceding the novel’s climax, he rearranges Nolan’s possessions to find evidence to plant at a later crime, for which he’ll frame Nolan, hoping to drive him and Harper apart. 

During the final judging for the town’s annual gardening competition, on the anniversary of Harper’s escape from Harvey Mead, Arthur experiences a cognitive lapse and accidentally incriminates himself in Peter Evanston’s death in front of the victim’s wife. In the ensuing chaos, the wife’s dog unearths a planted piece of evidence in Arthur’s garden: a bone with a titanium plate belonging to another of Harper’s victims, Bryce Mahoney. Harper manages to sneak the evidence away before it’s noticed but is certain Nolan planted it, as he was the only person she had told about the bone’s location in her freezer. That evening, she confronts him at gunpoint. Her pet raven, Morpheus, speaks her true name, “Autumn,” in a man’s voice—a name she believes only Nolan could have taught the bird. Convinced that his declarations of love are part of a cruel, long-planned revenge for his brother’s accident, she forces him out of her home and her life.

That evening, Yates reveals himself to Arthur as La Plume and attacks him. Arthur slits his own throat rather than let Yates kill him. The next day, Harper discovers Arthur murdered in the manor kitchen. A message is written in his blood on the wall, with a direct quote from a poetic note Nolan had given her. This discovery cements her belief that Nolan is the killer, when in reality Yates memorized the line from belongings in her and Nolan’s cottage. The police investigation, led by Yates, subtly steers suspicion toward Nolan. At Arthur’s funeral, as Harper grieves, Yates arranges for a tow truck to drive past carrying the rusted, barnacle-covered shell of her old van, which she had sunk in the ocean years ago, informing her it was recovered after an anonymous tip.

In the epilogue, Sheriff Yates reveals his true identity to Nolan, whom he has kidnapped and holds captive in a remote cabin. His goal is to systematically destroy Harper’s life, believing that this trauma will force her to shed her current identity and transform into his own “worthy legacy.” The book ends with Yates telling Nolan that Autumn Bower will be the one to kill him.
