⚠️ 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 (Complete and Chronological)

Margot and Jodie drive to the Waterford Mills storage unit just after midnight. Margot has already scouted the facility and knows Elliott Wallace’s unit number, seventy-four. Before leaving, Jodie retrieves bolt cutters from her garage and two baseball caps to avoid security cameras. Margot buys flashlights and latex gloves at a twenty-four-hour drugstore, explaining they are for avoiding fingerprints.

In the car, Jodie hesitates, suggesting alternatives like calling the manager or going to the police. Margot insists this is the only way because she lacks evidence for a search warrant. She gives Jodie the chance to wait in the car, but Jodie ultimately agrees to help, driven by her desire to prove that Wallace killed three girls and ruined Krissy’s life.

They approach the chain-link fence. Margot climbs over first, then tosses the bolt cutters over and Jodie follows. A passing car startles them but continues on. Outside unit seventy-four, they take turns cutting the padlock. It takes five attempts before the metal loop snaps and the lock falls. Another car approaches, so they hastily slide the door open and hide inside, pulling it shut.

Inside, the darkness is total. They turn on flashlights and survey the unit: a dresser, an old couch, a lamp, and stacks of cardboard boxes. The contents seem banal. Margot and Jodie split the search. Over two hours, they sort through books, clothes, and other ordinary items. Margot finds a copy of Lolita that disturbs her but is not evidence. They freeze at distant sounds, fearing discovery.

Finally, Margot opens the last box. She gasps and calls Jodie over. When Jodie looks inside, she claps a hand over her mouth and whispers, “Oh my god.” The chapter ends without revealing what they found, but the implication is that they have discovered something tied to Wallace’s crimes.

Character Development

Margot shows her determination and willingness to break the law for justice. She balances her personal reasons—wanting to focus on her uncle’s health and create stability for Luke—with the larger goal of stopping Wallace. Her leadership and calm under pressure drive the operation.

Jodie transforms from a hesitant accomplice into a resolute partner. Her initial fear gives way to a shared risk, and her physical effort cutting the lock demonstrates her commitment. Her motivation is deeply personal: Krissy Jacobs, the first victim.

Elliott Wallace remains an off-page presence, but the contents of his storage unit become the focus. His ordinary belongings contrast with the crimes he is suspected of, reinforcing the idea that evil can hide in plain sight.

Themes, Symbols, or Motifs

Desperation and illegality: Margot breaks the law because the official system has failed. Her choice shows how frustration with red tape can push people to extreme measures.
Small-town vulnerability: The storage facility’s outdated security—no barbed wire, likely nonfunctional cameras—reflects the theme of provinciality that Margot exploits.
Mundane hiding the monstrous: The box of classics and Lolita hints at a sophisticated persona masking predatory behavior. The ordinary furniture and clothes suggest that Wallace’s life appears normal.
Teamwork: Jodie and Margot share the physical and emotional burden. Their collaboration emphasizes that individual action is sometimes necessary when institutions lag.

Why This Chapter Matters

Chapter 31 is the climax of Margot’s investigation. It contains the breaking-and-entering sequence that leads directly to the discovery of evidence. The chapter shifts the story from suspicion to actionable proof. It also tests Margot’s ethics and deepens her bond with Jodie. The unresolved cliffhanger—what is in the box—creates urgency for the final chapters.

Study Questions and Answers

Why does Margot decide to break into Wallace’s storage unit rather than wait for a search warrant?
She believes time is running out. Wallace could slip away or harm another child. The police lack enough evidence for a warrant, so she takes matters into her own hands.
How does Jodie’s motivation for helping Margot differ from Margot’s own reasons?
Jodie is primarily driven by the desire for justice for Krissy Jacobs, the first victim whose life “Wallace ruined.” Margot has multiple motives: justice for Wallace’s victims, focus on her uncle’s health, stability for Luke, and a steady job.
What does the copy of Lolita in Wallace’s box suggest about his character?
The book’s themes of an older man’s obsession with a young girl parallel the crimes he is accused of. While not itself evidence, it reinforces the reader’s suspicion that Wallace’s interests are predatory.
