Short Summary

Mary Kubica’s Local Woman Missing fractures reality through three first‑person narrators. Sadie, a wife and mother, stumbles on a chilling computer search about her husband’s dead fiancée and a photograph that triggers buried recognition, while her son Otto claims she told him to bring a knife to school. Mouse, a six‑year‑old girl, lives in terror of her cruel stepmother — whom she calls “Fake Mom” — clinging to half‑remembered memories of her real father. Camille, an obsessive stalker, follows a man named Will to a remote island, fantasizing about killing his wife. Their stories collide around the stabbing death of Morgan Baines, a neighbor whose murder haunts the community. As hidden connections surface and memory itself proves suspect, the line between victim and predator blurs, building to a devastating truth.

Full Summary

Local Woman Missing opens with a collage of first‑person fragments that immediately destabilise the reader’s sense of truth. The novel weaves together three main threads, each narrated in a voice that can’t be fully trusted.

Sadie’s world unravels.
Sadie, a wife and mother, is finishing a shift at the optometry clinic on the island where she and her husband Will live with their two boys, Otto and Tate, and Will’s daughter from a previous relationship, Imogen. Driving home, she hears locals gossiping about the murder of Morgan Baines — a woman she barely knew — and is later confronted by Morgan’s widower, Jeffrey Baines. He tells her that Morgan had been frightened before she died and asks if Sadie knows why. Sadie denies any knowledge, though her own thoughts hint at secrets she’s buried.

At home, tension mounts. Imogen is practically a stranger, slipping in and out of the house without notice. Sadie and Will’s marriage has never fully recovered from his affair years earlier, and the scars show. Sadie’s nightmare‑like dreams and a sense of lost time make her question her own mind. While sorting through Will’s belongings, she finds a true‑crime novel containing a photograph of his former fiancée, Erin, who died in a car accident long before Sadie came into the picture. The photo unsettles her, and she realises that Will has since removed it, hiding it from her.

Then, Otto — her younger son — brings a knife to school and says his mother told him to do it. Sadie has no memory of that conversation. Horrified, she begins to wonder if she is losing her mind, or if some buried part of her is capable of violence. The police, already investigating Morgan’s murder, hear eyewitness statements that seem to place Sadie near the crime scene. Mr. Nilsson, an elderly neighbour, swears he saw Sadie arguing with Morgan and tearing out a handful of her hair. Sadie cannot recall any such encounter, but her work schedule from the clinic suggests she was working that day, providing a fragile alibi. Meanwhile, she discovers that someone has been searching the internet for information about Erin — a trail that leads right back to Will’s computer.

Mouse’s hidden torment.
In a separate, seemingly disconnected storyline, a little girl called Mouse tells her own story. She lives with a cruel and controlling stepmother she has named “Fake Mom.” When Fake Mom’s new husband — Mouse’s real father — is around, the woman performs sweetness; the moment he leaves, her mask drops. Fake Mom is emotionally and physically abusive, and Mouse clings to scraps of memory about her real mother and father, desperate to hold onto an identity that feels increasingly erased. The chapter reveals that Fake Mom’s pleasant façade hides a violent temper, and Mouse’s frightened, truncated voice makes the abuse feel immediate and terrifying. Early on, the connection between Mouse’s narrative and the adult storylines is deliberately unclear, but the sense of a child in danger is unshakable.

Camille’s dangerous obsession.
The third first‑person thread belongs to Camille, a woman driven by an all‑consuming fixation on a man named Will. She has stalked him to his island home, letting herself in when no one is around, touching his things, studying his wedding photograph. Camille’s thoughts are darkly candid: she fantasises about eliminating Sadie, about taking Will for herself, about the power she feels when she moves through his private spaces. Her voice is unnervingly rational as she describes her actions, and it becomes clear that she is both a threat and a deeply damaged person whose motives are rooted in a past that the novel slowly excavates.

Criss‑crossing suspicions.
As the narrative progresses, the three perspectives begin to interlock. Sadie’s investigation into Courtney Baines, Jeffrey’s ex‑wife, leads her to break into a car and a house, collecting clues that only confuse her further. She steals keys to sneak into Courtney’s Jeep and later programs the GPS to find Courtney’s home address, convinced that someone close to the Baines family might be the real killer. At the same time, the police bring Sadie in for questioning, showing her photos of the crime scene and pressing her about the missing murder weapon and a bloody washcloth that Sadie thought she saw but that has vanished.

Otto’s knife becomes a symbol of unspoken violence, while the computer search for Erin suggests that Will is keeping secrets from his own wife. Mouse’s voice provides a chilling counterpoint — a child whose entire existence is controlled by an abuser, a figure who, it becomes clear, might intersect with the adult world in a shocking way.

The reveal and its consequences.
Without spoiling the exact twist (see the Ending Explained page for a full breakdown), the novel’s climax pulls the three strands into a single, explosive revelation. Memory gaps, gaslighting, and multiple identities crash together, forcing the reader to reconsider every earlier assumption. Who killed Morgan Baines, and why? What is the true identity of Fake Mom? How are Camille, Sadie, and Mouse linked? The answers are devastating and speak directly to the themes of unreliable narration, childhood trauma, and the ways people reshape reality to survive.

Local Woman Missing is a taut, multi‑layered thriller that refuses to let any narrator stand on solid ground. By the final pages, the book challenges readers to distinguish between what actually happened and what the characters needed to believe to endure.

Ending Overview
