On a December afternoon during a blizzard, 18-year-old Toby Manx is at the Trail’s End Motel with his girlfriend Gwen Stapleton when he hears a distinctive two-handed knock on their door. He finds neatly folded yoga pants and a T-shirt in the snow, the signature of the “Lake Witch” game, a local courting ritual that began after the 2015 Independence Day Massacre. According to an award-winning paper by high school freshman Galatea Pangborne, the game requires teenagers to chase the person who left their clothes outside as foreplay for sex, explaining it as a way for them to combine trauma recovery with courtship rituals.
Curious to know who is courting him, Toby grabs his letterman jacket and pursues a hooded figure into the storm, wondering if it might be Wynona F. He reflects on his personal philosophy of staying in motion, like a shark, to keep the massacre’s trauma at bay. Gwen opens their room door and sees the abandoned clothes. After spotting the hooded figure near the vending machines and circling back to the motel’s front, Toby notices a massive dark shape in the parking lot resembling a trash truck.
Suddenly, something hot strikes Toby. He is disemboweled and soon dies.
This chapter, structured as Galatea’s report to her history teacher, Mr. Claude Armitage, chronicles serial killer Dark Mill South’s history from 2013 to December 2019. The Ojibwe serial killer operated across Wyoming, Montana, the Dakotas, Colorado, and Idaho under various names: the Eastfork Strangler (who branded victims), the Ninety-Eye Slasher (who used a machete), the Bowman Butcher (who used an axe), and the Rapid City Reaper (who electrocuted hanging victims). Authorities connected these crimes through evidence of left-handedness, eventually dubbing him the Nomad.
In July 2015, during the Elk Bend Massacre in Idaho, Sally Chalumbert attacked and mutilated Dark Mill South, severing his right hand with a shovel before he was captured trying to escape across the Salmon River. He survived electrocution in the water and was taken into custody. Dark Mill South claimed his goal was to kill 38 people to avenge the 1862 mass execution of 38 Dakota men.
After years of trials, Dark Mill South negotiated a plea deal in October 2019 to lead authorities to undiscovered bodies. On Thursday, December 12, 2019, an armored convoy began transporting him from Boise for this trip, which social media dubbed “The Reunion Tour.” A historic blizzard forced them off the interstate onto US Highway 20 toward Proofrock. Galatea reveals the Reunion Tour will end on Friday the 13th after 36 hours and 20 more deaths.
Twenty-two-year-old Jennifer Daniels, formerly known as “Jade,” walks across the narrow, icy top of Glen Dam during a blizzard to visit former Sheriff Angus Hardy in the control booth. Hardy, now the dam keeper, is severely injured from the 2015 massacre and uses a walker. Jennifer wears his old Carhartt jacket, given to her by the current sheriff, Rex Allen. They reconnect over coffee, and Hardy shows her a rare white spirit elk among a herd grazing the burnt ruins of the Terra Nova development.
Deputy Banner Tompkins arrives in a snowcat. He reveals that Sheriff Allen and Deputy Francie are searching for Dark Mill South’s missing convoy. Banner drops Hardy at his house, where Hardy briefly mistakes a photo of Dark Mill South for Jennifer’s father, Tab Daniels. Banner then drives Jennifer home to her house, which has been spray-painted with the words “Camp Blood.” Banner reveals that Hardy took the dam job to be near where his daughter Melanie drowned. Jennifer guesses that Banner became a deputy seeking the hero complex he developed saving Letha Mondragon during the massacre.
Banner and Jennifer receive a frantic emergency call from Cinnamon Baker at the Trail’s End Motel. Cinn reports that Toby Manx has been disemboweled and Gwen Stapleton has been hanged from a tree and mutilated. Trapped in a vehicle by a “monster,” Cinn kicks through the windshield, crawls over Toby’s body, and escapes into the storm. Banner and Jennifer find her stumbling down Main Street.
In another report for Mr. Armitage, Galatea details Jennifer Daniels’s legal ordeal following the 2015 Independence Day Massacre. Jennifer was arrested on July 6 after Tiffany Koenig’s viral phone video showed someone in Jennifer’s custodial coveralls killing people in Indian Lake. This included the apparent murder of Tab Daniels with a machete in a canoe.
Jennifer’s defense evolved through several strategies. She first claimed Stacey Graves, the ghost of a 103-year-old lake legend, was responsible. When that failed, she accused developer Theo Mondragon of prior murders, causing her defense team from the Baker Firm to withdraw. Her state-appointed attorneys then argued that Tab Daniels was already mortally wounded when Jennifer struck him, making her act one of self-defense rather than murder. Enhanced video showed Tab’s face was severely mutilated before Jennifer encountered him.
Retired Sheriff Angus Hardy’s testimony proved crucial: He stated he shot the real killer four times and Jennifer was in his field of view, providing reasonable doubt. On Valentine’s Day 2019, Jennifer was acquitted of Tab’s murder but immediately re-arrested on federal charges for damaging Glen Dam’s control booth. Her lawyers negotiated provisional release in December 2019, contingent on six months without property destruction. Sheriff Rex Allen collected her from Boise on December 10.
Galatea explains why she personally believes in Jennifer’s claim that Theo Mondragon was guilty of murder prior to the massacre: During the massacre, she was saved by Grade Paulson, the general laborer who had golden nails in his back. This was evidence Jennifer claimed proved Theo Mondragon’s guilt but which was officially denied.
On Friday morning, Letha Mondragon-Tompkins, Banner’s wife and Jennifer’s former classmate, picks up Jennifer in her truck. Letha suffers permanent jaw injuries from the 2015 massacre, requiring reconstructive surgery, a liquid diet, and a complex medication regimen. Her one-year-old daughter, Adrienne, sits in the backseat. Letha reveals she named Adrienne after Adrienne King, who played the final girl Alice in Friday the 13th. She asks Jennifer to be Adrienne’s aunt, so that she can provide a better female voice model for Adrienne’s speech development. Jennifer agrees.
Letha and Jennifer discover that Cinnamon Baker has escaped through an unsecured bathroom window in the sheriff’s office. Banner and Jennifer track her footprints through the blizzard and find her trying to reach Pleasant Valley nursing home to warn people. Jennifer insists they take Cinn there for medical care. Banner drops them off before returning to Letha at the station.
Inside Pleasant Valley, Jennifer learns from a desk clerk that two staff members, Mark and Kristen, are missing on break. The clerk directs her to room 428. Jennifer finds Mark dead on the bed, his corpse staged to mimic Kevin Bacon’s death in Friday the 13th. In the bathroom, Kristen’s corpse replicates another kill from the same film. Cinn appears in the doorway, having come to warn her friends, and screams. As staff rush to the scene, the clerk mentions he thought Cinn was visiting her sister. Jennifer is surprised to learn from the clerk that Cinn has a sister.
The narrative immediately establishes its framework of intertextuality by situating acts of violence within the established conventions of the slasher film genre. The murders are staged performances that replicate iconic kills from famous slasher movies. Gwen Stapleton’s death is a direct homage to the opening of Scream, a film known for its self-referential commentary on horror tropes. Similarly, the murders of Mark and Kristen at the nursing home are precise recreations of kills from the original Friday the 13th. This self-awareness extends to the characters themselves; upon hearing the details of Gwen’s murder, Jennifer immediately thinks of “Casey Beck[er]—” (45), the first victim in Scream. By embedding these references, the narrative suggests that the characters’ understanding of their reality is mediated through the fictions designed to terrify them, exploring the porous boundary between lived trauma and its cultural representation.
This exploration of narrative is further developed through the novel’s structure, which juxtaposes conventional third-person prose with stylized, pseudo-academic reports. The chapters attributed to student Galatea Pangborne provide historical context and exposition, framing Proofrock’s violence as a subject for academic inquiry. Her analysis of the Lake Witch game, a local courting ritual born from tragedy, argues that it is a process through which trauma and adolescent social rituals become “intertwined” (2). This detached, sociological lens attempts to impose order on chaos. However, the form of the game itself underscores the theme of The Instability of Truth and Narrative. The reveal at the close of Chapter 4 that Galatea has a personal connection to Jade and the Independence Day Massacre retroactively destabilizes her perceived objectivity. Her scholarly voice is also a performance, a curated narrative demonstrating that even historical accounts are inevitably shaped by individual perspective.
The psychological and physical toll of surviving violence is embodied in the characters of Jennifer Daniels and Letha Mondragon-Tompkins, whose reunion anchors the theme of Female Survival and Self-Determination in the Face of Patriarchal Violence. Jennifer returns to Proofrock as a survivor whose identity has been shaped by a protracted legal battle, rejecting the “Jade” persona she constructed in high school. Letha’s trauma is physically manifest; her jaw, now partially reconstructed, is a constant reminder of her near-fatal injuries. Yet, rather than focus on the trauma of her past, Letha is concerned with constructing a protected future for her daughter, Adrienne. Her desire for Jennifer to become “Aunt Jennifer” is a strategic attempt to build a matriarchal support system, hoping her daughter will grow to be a “fighter” (69). This partnership signifies a conscious effort to reclaim their narratives, pivoting from suffering to resilience, so that they can pass down a legacy of strength rather than fear.
The novel broadens its scope from personal suffering to collective historical grievance with the introduction of Dark Mill South, whose motivations are explicitly tied to Historical Trauma as a Perpetual Cycle of Violence. His goal to kill 38 people is a direct response to the 1862 mass execution of 38 Dakota men, reframing his rampage from a spree of random terror to a calculated act of historical retribution. This backstory prevents him from being a simple, unknowable monster in the slasher tradition and instead positions him as a violent consequence of America’s colonial history. The narrative underscores this connection when the narrator of his chapter quotes a poster in a history classroom: “Blood alone moves the wheels of history” (19). This framing argues that South’s violence is an extension of a foundational national violence.
Ultimately, these chapters establish Proofrock as a space where the past is an active, invasive force that distorts perception and dictates the present. The landscape itself is a repository of trauma; Angus Hardy, for instance, works at the dam to be near where his daughter drowned. This constant presence of history bleeds into the characters’ consciousness, as seen when Hardy momentarily mistakes Dark Mill South’s photograph for that of Tab Daniels. Such moments of confusion illustrate how personal and historical traumas are layered over reality, creating a psychological environment where every event is filtered through the lens of prior violence. In a place so saturated with grief, the narrative suggests, distinguishing between a new threat and the ghosts of the old becomes nearly impossible.
