Jet attends the Woodstock Halloween Fair, clashes with ex‑boyfriend JJ Lim, deals with intense family drama involving brother Luke, sister‑in‑law Sophia and baby Cameron, meets local officials Gerry Clay, Sergeant Jack Finney and Chief Lou Jankowski, survives a drunken‑clown altercation, returns home, eats cookies, and is brutally killed in her own house, triggering an emergency 911 call.
Jet awakens in a hospital, learns she suffered multiple head blows causing a subdural hematoma, a rare clivus fracture with a bone fragment pressing on her basilar artery, and discovers she also has polycystic kidney disease that weakens her arterial walls; doctors warn an aneurysm will form and offer a high‑risk surgery with <10% survival chance.
Jet awakens in a hospital after being violently attacked. Doctors reveal a subdural hematoma, a rare clivus fracture with a bone fragment compressing her basilar artery, and polycystic kidney disease that weakens her vessels, warning of an imminent aneurysm and offering a high‑risk surgery with less than 10 % chance of survival. The police—Detective George Ecker, Sergeant Jack Finney, and Chief Lou Jankowski—interrogate her, learning that her iPhone 14 and Apple Watch are missing and extracting the watch passcode “0709.” Dr. Lee diagnoses Jet with anomic aphasia affecting word retrieval. Her mother Dianne Mason, father Luke, and brother (implied by “Scott”) pressure her to consent to the operation, but Jet rejects the immediate surgery, choosing to delay in order to have the promised seven days to live and solve her own murder.
Jet and the police inspect the house crime scene; spatter analysis shows three head blows—two while standing, one on the floor—indicating a tall, right‑handed attacker; the side/back door was likely left unlocked for entry; the attack occurred between 10:40 pm and 11:00 pm; Reggie the dog survived; Jet’s iPhone and watch are missing; the doorbell camera captured only the victim’s arrival, not the assailant; investigators note the weapon has not been recovered and the scene is cleared for cleaning.
Jet determines the attack occurred at 10:46 pm using her Apple Watch heart‑rate spike, discovers her iPhone was turned off at 10:56 pm on River Street near the Elm Street Bridge (less than five minutes from her house), and sees an apologetic text from ex‑boyfriend JJ at 10:58 pm. She gives detectives the watch passcode “0709,” confirms the murder was opportunistic and likely committed by someone she knows who brought the weapon, and the police move to canvass the River Street area.
Jet spends the night obsessively reviewing her Ring doorbell footage, watching multiple motion‑detector alerts (10:39 p.m., 11:05 p.m., 8:33 p.m., etc.) and noting that the killer never appears on camera. She records her observations in a notebook (crossed‑out app ideas, “Who murdered me?”), logs the timestamps, and replays videos of Billy’s frantic rescue attempt, the paramedics, and a bizarre Halloween‑fair clip featuring costumed teens. She investigates a “cookie mystery” involving Sophia’s deliveries, reconstructs the timeline of Sophia’s two trips to the house, and briefly searches brain‑aneurysm symptoms before deciding not to read further. The chapter adds concrete evidence that the murderer entered unseen, that Jet believes the assailant is someone she knows, and that she is actively using the Ring dashboard and her notebook to piece together the night’s events.
Jet rejects the family‑pressured emergency brain surgery, denounces her parents’ coercion, and storms out after her mother pushes funeral catalogs on her. She drives to Billy’s apartment, begs to stay, and Billy reluctantly agrees to let her crash there.
Jet discovers a fraudulent $30,000 loan taken out against her 1986 Ford F‑150, indicating identity theft that may be tied to her recent attack. She learns Billy keeps a spare key under the front‑door mat and obtains it, then decides to follow the River Street location where her phone was turned off, using the key to leave the house and pursue the new lead.
Jet receives a threatening loan‑demand letter revealing a recent $30,000 loan taken out in her name; detectives find a synthetic red wig hair at the crime scene, indicating the killer wore a red wig (potentially linking to ex‑boyfriend JJ); Jack Finney shows Jet the hair evidence; Ecker reports no eyewitnesses from River Street and a fruitless grid search; Jet’s mother files a missing‑person report; Jet warns LightFi about seizing her truck.
Jet and Billy examine the red wig hair recovered from the murder scene, connecting it to suspect JJ/Andrew Smith; they decide to obtain photographs from Owen Clay to verify the wig, Billy administers first‑aid for Jet’s leaking head wound, and they plan to report their findings to the police the following morning.
Jet and Billy go to Gerry Clay’s house on Pleasant Street, compel his teenage son Owen to give them 628 unedited Halloween Fair photos; they spot a red wig on JJ Lim in the photos and the same wig on Andrew Smith, linking the wig to the murder and naming Andrew a suspect; Jet threatens Owen about his hidden porn files and destroys a parking ticket she finds on her windshield.
Jet and Billy interrogate Andrew Smith at Dr. Mandrake’s Dive Bar, learning that Sergeant Finney left Jet’s apartment at 10:29 PM; Andrew reveals his daughter Nina’s suicide, his mother Dianne’s conflict with the Mason family, that Luke sold Andrew’s house and that the Mason family home is being demolished for a new McMansion; Andrew discloses that Chief Lou Jankowski’s wife, Nell Jankowski, will buy Mason Construction, and that Jet’s father (Scott Mason) plans to sell the company to Nell rather than to Luke, giving Andrew a motive against Jet’s family; Jet and Billy consider searching Andrew’s apartment for her iPhone and realize they were looking at the wrong street (North vs River Street).
Jet and Billy breach the Mason Construction site on North Street, smash newly poured concrete and recover Jet’s iPhone and the murder‑weapon hammer hidden in the foundations. A confrontation erupts with foreman Jimmy and brother Luke; police arrive and Detective Ecker warns about chain‑of‑custody issues. Jet pressures her family for a list of all Mason Construction workers, expanding the suspect pool to include Andrew Smith and anyone with knowledge of the site’s concrete schedule.
Jet and Billy learn the murder weapon is a hammer that only comes in a North‑American 60‑piece tool set, narrowing the suspect pool. Jet dresses in Billy’s flannel and goes to his bar gig, where she meets Chief Jankowski’s wife Nell, who confirms that Jet’s father plans to sell Mason Construction to her, giving Andrew Smith a clear motive. The bar scene also deepens Jet and Billy’s personal revelations and their strained family histories.
Jet uncovers that Sophia and Luke falsified their alibis, decides to obtain a list of Mason Construction employees and to contact Henry—JJ’s injured brother—for leads, and is met with a gun pointed at her when she forces entry to the house.
Henry appears with a gun, lies about his employment at Mason Construction and about JJ’s whereabouts, and refuses to help Jet; Jet’s ongoing brain‑aneurysm fears and her worsening health are highlighted; a hallucinatory “doubling” episode shows Jet’s mental breakdown; after a brief nap in Billy’s bedroom Jet discovers her right arm is completely paralyzed and, with Billy’s help, they rush her to the hospital.
