Halloween Fair, Old Wounds

Jet Mason, 27, returns to her small Vermont town for Halloween, still living at home after dropping out of law school. At the town fair, she navigates awkward encounters with her ex-boyfriend JJ, her brother Luke, and former best friend Sophia (now Luke's wife). Family tensions simmer: Jet feels like a failure, Luke is desperate to inherit the family construction business, and Sophia is distant. The night is full of small slights, old resentments, and the sense that Jet is stuck while everyone else has moved on. The fair ends with Jet feeling isolated, her relationships frayed, and a sense of foreboding in the air.

The Attack and Aftermath

After the fair, Jet returns home alone. She's ambushed from behind, struck three times in the head with a hammer, and left for dead. Her dog's screams alert neighbor Billy, who finds Jet bleeding out and calls 911. Jet is rushed to the hospital, barely surviving. When she wakes, she learns she has a rare, fatal brain injury: a bone fragment is pressing on a major artery, and due to her genetic kidney disease, she has only days to live unless she risks a near-hopeless surgery. The family is devastated, and Jet is forced to confront her mortality and the unresolved issues in her life.

Seven Days to Live

Doctors tell Jet she has less than a week before an aneurysm kills her. Surgery offers less than a 10% chance of survival. Her family pressures her to try, but Jet refuses, choosing to live her last days on her own terms. She decides to use her remaining time to solve her own attempted murder, determined to do something meaningful before she dies. Jet's decision fractures her family further, but she is resolute: she will not die without answers.

Jet's Choice: Solve Her Murder

Jet returns home, determined to find her attacker. She examines the crime scene, reviews doorbell camera footage, and interviews family and friends. She enlists Billy, her childhood friend, as her partner. The police focus on JJ, her missing ex, but Jet is unconvinced. She discovers her phone and the murder weapon are missing, and the attacker likely knew the house well. Jet's investigation is both a race against time and a way to reclaim agency over her life.

Crime Scene and Clues

Jet and Billy analyze the timeline using her Apple Watch, pinpointing the exact time of the attack. They discover a synthetic red wig hair at the scene, suggesting the attacker wore a costume. Reviewing Halloween photos, they find two suspects wore red wigs: JJ and Andrew Smith, a bitter, alcoholic neighbor with a grudge against the Masons. Jet also finds her phone was last active near a Mason Construction site, where new foundations were poured the morning after her attack. She suspects the killer hid evidence there.

Family Secrets and Suspects

Jet's investigation reveals that nearly everyone close to her is hiding something. Luke and Sophia lie about their whereabouts the night of the attack. Sophia is caught sneaking into the Mason house, and Jet discovers evidence of identity theft: someone took out a loan in her name. Jet's family is fracturing under the strain, and old wounds—especially the death of Jet's sister Emily years ago—resurface. Jet begins to suspect that the motive for her attack is rooted in family secrets and the future of the family business.

The Red Wig Mystery

Jet and Billy confirm that both JJ and Andrew Smith wore similar red wigs on Halloween. The police focus on JJ, especially after discovering he took out a fraudulent loan in Jet's name. But Jet is skeptical: the timeline and evidence don't fully fit. She also learns that Andrew Smith has a deep grudge against the Masons, blaming them for his daughter's suicide and the loss of his home. The red wig clue keeps the suspect pool open, but Jet senses the real motive is more complex.

The Hammer and the Foundations

Jet and Billy, suspecting the killer hid evidence at the construction site, break into the newly poured foundations. After backbreaking work, they find Jet's phone and the hammer, wrapped in a Mason family dish towel. The police take over, but Jet realizes the killer had to know about the construction schedule—pointing to someone close to the family or business. The police still focus on JJ, but Jet is convinced the answer lies within her own circle.

Poison in the Pills

Jet discovers that Sophia has been tampering with her father's blood pressure medication, replacing it with salt to worsen his kidney disease and force him into retirement. Sophia confesses she did it to help Luke inherit the company sooner. Jet realizes that multiple murder plots are unfolding in her family, and that the attack on her may be connected to the high-stakes battle over the business. The web of lies and betrayals grows ever more tangled.

Sophia's Betrayal

Jet confronts Sophia, who admits to poisoning Jet's father but denies involvement in the attack. Jet also confronts Luke, who is evasive and angry, and seems to be hiding something about the night of the attack. Jet's investigation reveals that Luke has been committing financial fraud at Mason Construction, paying employees off the books and exposing the company to legal ruin. The family's secrets are on the verge of exploding.

The Mason Construction Fire

As Jet and Billy search for more evidence at Mason Construction, the building is set on fire with them inside. They barely escape. The police arrest Jet for arson, based on evidence planted by the real culprit. In jail, Jet writes goodbye letters to her loved ones, believing she will die before she can clear her name or solve her murder. Billy provides an alibi, and Jet is released, but the clock is running out.

Jail, Goodbyes, and Letters

In jail, Jet reflects on her life, her regrets, and the people she loves. She writes heartfelt letters to her family and friends, especially Billy, confessing her feelings and the truth about past mistakes. When she is released, she and Billy race to solve the final pieces of the puzzle, knowing Jet's time is almost up. The urgency is palpable, and every moment is precious.

Emily's Secret

Jet and Billy discover that Jet's sister Emily, who drowned years ago, may have been murdered. Old messages reveal Emily overheard a family secret about Luke's parentage and was planning to tell someone before she died. Jet and Billy realize that the trauma of Emily's death—and the secrets surrounding it—are at the heart of the current violence. The past and present are inextricably linked.

The Truth About Luke

Jet confronts Luke, who confesses to killing Emily in a fit of rage as a teenager, then staging it as an accident with the help of an adult. Luke reveals he is not Scott Mason's biological son, but the son of someone else close to the family. The revelation explains much of the family's dysfunction and the lengths people have gone to protect secrets. Jet realizes the real killer is someone who has always been in the background.

The Real Killer Revealed

Jet and Billy deduce that the real killer is Jack Finney, Billy's father and the longtime neighbor. Jack is also Luke's biological father, the result of an affair with Dianne Mason. Jack killed Jet to ensure Luke would inherit Mason Construction, seeking to give his secret son the life he never had. He staged the evidence to frame JJ and tried to kill Jet again in the fire. The motive is a toxic mix of love, resentment, and a desire to control the family's legacy.

Billy's Confession

As Jet's aneurysm ruptures, she and Billy share a final, emotional goodbye. Billy confesses his love, and Jet assures him she knows he is not the killer. Jet dies in Billy's arms, at peace with her choices and the truth. Billy promises to finish what Jet started and ensure justice is done.

Endings and Beginnings

In the aftermath, Billy confronts his father, extracting a confession and ensuring the truth comes out. Luke, devastated by the revelations, is forced to reckon with his actions. The Mason family is forever changed, but Jet's determination and courage bring long-buried secrets into the light. Billy, carrying Jet's memory and her final letter, begins to heal and look toward the future, honoring Jet's legacy by choosing to live fully.

Characters

Jet (Margaret) Mason

Jet is a 27-year-old woman who feels stuck and unfulfilled, living at home after dropping out of law school. She is sharp, sarcastic, and deeply wounded by her family's expectations and the loss of her sister Emily. Jet's psychological journey is one of reclaiming agency: faced with imminent death, she chooses to solve her own murder, seeking meaning and closure. Her relationships are fraught—resentful of her brother Luke, betrayed by Sophia, and estranged from her mother. Jet's bond with Billy is the emotional core of the story, evolving from childhood friendship to something deeper. Her arc is about confronting the truth, accepting her flaws, and finding peace in her final days.

Billy Finney

Billy is Jet's childhood best friend and neighbor, a kind, sensitive man who has always loved Jet. He is haunted by abandonment (his mother left when he was young) and a sense of inadequacy. Billy is the emotional anchor for Jet, supporting her investigation and providing comfort as her health declines. His own journey is about self-worth and courage: he must confront the truth about his family, his feelings for Jet, and ultimately, his father's crimes. Billy's love for Jet is unwavering, and his grief is profound, but he finds strength in honoring her memory.

Luke Mason

Luke is Jet's older brother, desperate to inherit the family business and prove himself. He is driven, stressed, and increasingly compromised—committing financial fraud and turning a blind eye to Sophia's poisoning of their father. Luke's psychological complexity is rooted in his identity crisis: he is not Scott Mason's biological son, a fact that warps his sense of belonging and worth. His rage and guilt over Emily's death, and his complicity in family secrets, make him both a suspect and a victim. Luke's arc is one of reckoning and, possibly, redemption.

Sophia Mason

Sophia was once Jet's closest friend but is now married to Luke. She is ambitious, image-conscious, and desperate for security. Sophia's betrayal—poisoning Jet's father to hasten Luke's inheritance—stems from her fear of losing status and control. Her relationship with Jet is fraught with jealousy and unresolved hurt. Sophia's actions are both villainous and pitiable, reflecting the corrosive effects of family dysfunction and small-town pressures.

Dianne Mason

Dianne is Jet and Luke's mother, a powerful figure in the town and the family. She is fiercely protective, manipulative, and emotionally distant, especially after Emily's death. Dianne's greatest secret is Luke's true parentage, the result of an affair with Jack Finney. Her inability to confront the past or show vulnerability contributes to the family's unraveling. Dianne's arc is about the cost of denial and the destructive power of secrets.

Scott Mason

Scott is the patriarch of the Mason family, owner of Mason Construction. He is kind but passive, struggling with kidney disease and the burden of family expectations. Scott's reluctance to retire or choose between his children exacerbates family tensions. He is ultimately a victim of Sophia's poisoning and the family's web of lies.

Jack Finney

Jack is Billy's father, longtime neighbor to the Masons, and the biological father of Luke. Outwardly affable and respected, Jack is consumed by resentment and a sense of loss—his affair with Dianne ended after Emily's death, and he feels excluded from the family and the business. Jack's psychological unraveling leads him to murder Jet, frame JJ, and attempt to kill Jet again in the fire, all to secure a legacy for Luke. His actions are driven by a toxic mix of love, envy, and entitlement.

Andrew Smith

Andrew is a bitter, alcoholic neighbor who blames the Masons for his daughter's suicide and the loss of his home. He is a suspect due to his grudge and presence at the fair, but ultimately is not the killer. Andrew represents the collateral damage of the Mason family's actions and the town's economic divides.

JJ Lim

JJ is Jet's ex, initially the prime suspect due to circumstantial evidence and his own financial desperation. He is revealed to be guilty of fraud but not violence. JJ's arc is about regret and the consequences of bad choices, but he is ultimately a victim of the real killer's machinations.

Emily Mason

Emily's drowning years ago is the family's foundational trauma. Her death, initially ruled an accident, is revealed to be a murder committed by Luke and covered up by adults. Emily's secret—overhearing the truth about Luke's parentage—sets the entire chain of events in motion. She is a ghostly presence, her absence shaping every character's psychology.

Plot Devices

Ticking Clock / Terminal Diagnosis

Jet's fatal brain injury gives her a literal deadline: seven days to live. This device creates relentless urgency, heightens emotional stakes, and forces Jet (and those around her) to confront truths they would otherwise avoid. The countdown structure also mirrors the classic "locked room" or "closed circle" mystery, but with the protagonist as both detective and victim.

Unreliable Memory and Family Secrets

The novel uses unreliable memory—especially around Emily's death—to create ambiguity and suspense. Family secrets, hidden motives, and generational trauma are gradually revealed through investigation, old messages, and confrontations. The truth is always just out of reach, distorted by time, guilt, and denial.

Red Herrings and Shifting Suspects

The narrative structure introduces and discards suspects—JJ, Andrew, Sophia, Luke—using costume clues, alibis, and motives. Each new revelation deepens the mystery and implicates someone else, until the final twist reveals the true killer hiding in plain sight.

Symbolism of the House and Inheritance

The Mason house, the construction business, and the act of building (and destroying) are recurring symbols. They represent legacy, belonging, and the destructive power of secrets. The fight over inheritance is both literal (the business) and metaphorical (who gets to define the family's story).

Letters and Final Goodbyes

Jet's letters, written in jail as she faces death, provide emotional closure for the characters and the reader. They allow for confessions, forgiveness, and the articulation of lessons learned. The device also underscores the theme of communication—what is said, unsaid, and left too late.

Analysis

Not Quite Dead Yet is a propulsive, emotionally charged mystery that uses the ticking clock of impending death to strip away pretense and force its characters—and readers—to confront the truths we most fear. Holly Jackson reimagines the classic whodunit as a race against mortality, blending sharp psychological insight with a deeply human story of regret, love, and the longing for meaning. The novel interrogates the corrosive effects of secrets, the ways families wound and protect each other, and the desperate need to matter before time runs out. Jet's journey is both a gripping investigation and a meditation on what it means to live fully: to choose agency, to seek truth, and to love without guarantees. The final twist—that the killer is the trusted neighbor, acting out of twisted love and resentment—underscores the dangers of unexamined loyalty and the generational cycles of harm. Ultimately, the book's lesson is that life's meaning is found not in grand achievements, but in the small, honest moments of connection, courage, and forgiveness. In her last days, Jet finds what she was searching for all along: not just the answer to her murder, but the freedom to live—and die—on her own terms.
