Chapter 5: Piecing Together the Attack

⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.

Summary

As crime-scene cleaners process the house, Jet’s father brings her a sandwich made from freezer bread and “good cheese.” Her mother arrives and again pressures Jet to reverse her decision to die in a week, but Jet refuses.
Jet’s analytical mind takes over: she points out that nothing was missing from the house and that the attacker struck three times, the last blow delivered when she was already incapacitated. She concludes the killer brought the murder weapon and came with the intent to kill—meaning the attacker is someone she knows.

When Detective Ecker tries to leave, Jet stops his car and persuades him to let her help. She asks to see her Apple Watch, enters the passcode, and examines the heart-rate data. A spike to 158 bpm and a sharp drop to 56 bpm pinpoints the time of the attack: 10:46 p.m.

Next, Jet checks her messages. A text from her mother at 10:48 p.m. is innocuous. But a message from ex-boyfriend JJ—saved in her contacts as “Don’t Pick Up”—reads simply “Sorry” and was sent at 10:58 p.m., after the attack. The police grow suspicious of JJ.

Jet remembers she can use Find My Phone. The watch shows her iPhone last connected at 10:56 p.m. on River Street, near the corner of North Street. She writes down the timeline on a sheet of paper:

10:46 p.m. – Time of murder
10:56 p.m. – Phone turned off, last location River Street
10:58 p.m. – “Sorry” text from JJ

While she finishes her notes, Sergeant Jack Finney points out that someone has come to see her. It is Billy Finney, Jack’s son, who has brought Jet’s dog Reggie. Billy explains he found his father’s wallet on The Green and was walking to the house to return it when he heard Reggie screaming and discovered Jet’s body.

Billy hugs Jet—the first person to do so since the attack. Unaware of her prognosis, he says he is glad she survived. Jet apologetically tells him she will be dead in a week. Billy is devastated, stumbling backward with the news.

Jet deduces the killer is someone she knows: nothing was stolen, the weapon was brought to the house, and the third blow was meant to ensure death.
Jet convinces Detective Ecker to involve her in the investigation.
Apple Watch heart-rate data reveals the exact time of the attack: 10:46 p.m.
A message from ex-boyfriend JJ at 10:58 p.m. reads “Sorry,” raising suspicion.
Find My Phone locates Jet’s iPhone at 10:56 p.m. on River Street.

Character Development

Jet: Demonstrates sharp reasoning under pressure, using forensic clues (no robbery, the weapon brought to the scene) to understand the attack. She is proactive and persuasive, convincing Ecker to cooperate. Despite her fatal prognosis, she keeps her sense of humor (“If you’ve gotta die, might as well be funny about it”) and remains determined to solve her own murder.
Detective Ecker: Initially dismissive, he warms slightly to Jet’s help after seeing her insightful interpretation of the evidence. He remains guarded (“Cop speak for: Maybe”).
Billy Finney: Deeply caring and emotional. He is the first person to physically hug Jet, and his devastation when learning she will die shows his genuine affection and hope that was misplaced.
Mom and Dad: Mom continues to push Jet to change her mind, while Dad quietly supports her without pressure.

Themes, Symbols, or Motifs

Evidence vs. Instinct: Jet combines hard data (heart-rate graph, Find My Phone) with logical deduction (the implication of the third blow, the weapon being brought) to advance the investigation over police procedure.
Time and Urgency: The Apple Watch data gives a precise minute; the deadline of “dead in a week” intensifies every discovery. Jet even writes a physical timeline to anchor her own failing memory.
Trust: Jet declares Billy is the one person she trusts not to be the killer, yet she must question others, including her ex-boyfriend and anyone in her circle.
Isolation of the Dying: Jet’s mother cannot accept her decision; Billy’s sorrow reflects how others cannot handle the truth. Jet’s humor becomes a shield against their grief.

Why This Chapter Matters

This chapter marks the real beginning of Jet’s investigation. She moves from being a victim to an active, clever detective. The timeline and evidence she uncovers (time of attack, location of the phone, the “Sorry” text) are foundational clues. Additionally, the emotional blow to Billy raises the stakes: those who love Jet must now grapple with her impending death, and Jet herself must navigate those relationships while racing the clock.

Study Questions

What evidence does Jet use to conclude that the killer is someone she knows, rather than a stranger?
Answer: Jet notes that nothing was stolen from the house, the killer brought the murder weapon with them, and the third blow indicates purpose to kill—not merely to escape. Therefore, the attack was premeditated and targeted, meaning the killer is likely known to her.
How does Jet use the Apple Watch to determine the exact time of the attack?
Answer: She accesses the heart-rate data for Halloween. A spike to 158 bpm (likely from hearing footsteps or the first blow) followed by a sharp drop to 56 bpm (likely loss of consciousness) appears at a specific timestamp. She touches the line to read the time: 10:46 p.m.
Why does the “Sorry” text from JJ at 10:58 p.m. make the police suspicious?
Answer: The text was sent twelve minutes after the attack and same contact’s name is changed to “Don’t Pick Up,” implying a troubled relationship. While Jet suggests the timing is strange because the killer took her phone, the police consider that the text could be symbolic or that JJ might have sent it knowing the phone was still on her person.
