Chapter 31 Summary: Tracking Carrie via AirTag
⚠️ 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
Lo explains her full theory to Judah, showing that only Carrie’s involvement makes every key-card entry, phone call, and Carrie’s own actions consistent. However, Lo cannot share this with the police without confessing that she helped a wanted criminal flee and possibly commit a second murder. Judah points out that Carrie stole Lo’s suitcase, which contains an AirTag he placed last summer. Using the Find My app, they locate the suitcase in a small house in Woodingdean, near Brighton. Lo decides she must confront Carrie first to hear her side before calling the police, even though she risks prosecution for obstruction. Judah reluctantly agrees to accompany her.
Key Events
- Lo convinces Judah that Carrie is the only person who can explain all the evidence.
- Lo admits she cannot go to the police without incriminating herself for aiding Carrie’s escape.
- Judah reveals he planted an AirTag in Lo’s suitcase, which Carrie later stole.
- They track the AirTag to a modest house in Woodingdean, a town near Brighton.
- Lo insists on confronting Carrie in person before deciding whether to call the police.
- Judah accepts the plan, though he remains skeptical of Carrie’s innocence.
Character Development
- Lo faces a moral and legal dilemma: her desire for justice clashes with her fear of prosecution. Her decision to confront Carrie shows a need for certainty over self-preservation.
- Judah shifts from frustration to practical support, acknowledging that Lo’s reasoning about self‑risk is valid. His willingness to accompany her deepens their partnership.
- Carrie remains an off‑page enigma; the chapter reinforces her evasiveness (she never spoke about family, may not be her real name) but now offers a tangible lead.
Themes, Symbols, or Motifs
- Paranoia and Surveillance: The AirTag, originally a mundane anti‑loss tool, becomes an instrument of pursuit. The map view transforms a person into a blue dot, reducing Carrie to a traceable object.
- Trust vs. Proof: Lo’s need to “hear her side” reflects a desire for direct testimony, even when circumstantial evidence seems overwhelming.
- Consequences of Complicity: Lo’s earlier decision to help Carrie now threatens her own freedom; the chapter underscores that aiding a fugitive has lasting legal repercussions.
Why This Chapter Matters
This is the turning point where passive suspicion becomes active investigation. The AirTag gives Lo (and the reader) a concrete location, shifting the story from a locked‑room mystery to a pursuit. It also forces Lo to choose between protecting herself and seeking the truth, a choice that will shape the novel’s climax.
Study Questions and Answers
-
Why does Lo decide to confront Carrie before contacting the police?
Lo fears that reporting Carrie will also expose her own role in helping Carrie avoid arrest. She wants to be absolutely certain of Carrie’s guilt so that the risk of prosecution is worth it, and she hopes to get Carrie’s full story before involving law enforcement. -
How does Judah’s AirTag solution change the investigation?
It provides a real‑time location for Carrie, who had vanished without a trace. The AirTag transforms a dead end into a lead that can be physically followed, enabling Lo to take direct action rather than relying on police resources. -
What does this chapter reveal about the relationship between Lo and Judah?
Despite earlier tension over Lo’s secrecy, Judah now stands by her. He listens to her reasoning, offers a practical fix, and agrees to accompany her even though he disapproves of her plan. Their partnership is tested but ultimately strengthened.
