Let's dive in.

Summary

Stevie returns to London alone at night, having missed her flight. She takes the Heathrow Express to Paddington, her phone nearly dead. She has just enough battery to send one text message before the train arrives. She navigates the streets on foot, winding her way back to Angela's house.

Izzy is waiting outside, wearing a blue coat and a pom hat, her eyes puffy from crying. Doorknob, Angela's cat, winds around her legs. Izzy greets Stevie with a question about her missed flight, and Stevie admits she'll be in trouble. Stevie explains that she saw something earlier that will make everything make sense, and she needs to look at everything again.

Inside, the house feels abandoned and cold. Doorknob runs around frantically. Stevie immediately goes to the cabinet under the stairs, which is still partway open. She digs through Doorknob's hidden treasures—a dead mouse, a used tea bag, a dirty cotton swab, a tissue—and finds two buttons. One is bright pink, the other silver. She sets them on the coffee table.

Izzy examines them. She thinks the pink one might come off a sweater Angela owns. The silver one has a label that says Stella McCartney. Izzy checks her phone and says Stella McCartney wasn't designing in the nineties, but the button might be from 2001. She thinks she might know what it's from because she borrowed it once.

Stevie is initially disappointed, but she decides to search the house thoroughly. She plugs in her phone, puts on Britpop music, and explores the upstairs. In the bedroom, she notes Angela's neatness—folded cashmere sweaters, shoes in clear boxes, a single book on the bedside table (a biography of Catherine Howard). In the bathroom, she checks the medicine cabinet: floss, deodorant, toothbrush heads, skin cream, nail polish remover, indigestion medicine, birth control pills, cold medicine. No sleeping pills.

In the office, she examines the bookshelves, photographs, and posters from the Nine's shows. She sits in the desk chair and spins, thinking about Angela's box of evidence and how she found Samantha Gravis. She wonders about the connection: Samantha had a blow to the head and sank in shallow water; Angela was full of medicine to make her sleepy; Rosie and Noel suffered. She asks the light fixture, “What did you know?”

Doorknob comes in and rubs against her. She picks him up and writes a list: “A lock, a button, Samantha Gravis.” She feels a sizzling sensation between her eyes. She runs downstairs to the kitchen, where Izzy is washing moldy, curry-stained dishes. Stevie asks to see Angela's text messages again.

Izzy gets the tablet. Stevie scans the exchange: at 9:46 p.m., Angela texts “She had the button.” Theo, Sooz, Yash, Peter, and Sebastian respond with confusion. At 9:55, Theo asks “Ange?” Stevie notes that Angela received a call at 9:53—seven minutes after her last text. She repeats “seven minutes” over and over, almost shaking. She looks around the kitchen in desperation, yelling “What the hell did I see?”

She decides to recreate the scene. She asks Izzy to sit where she was sitting the other night. Izzy recalls they were talking about history—the Tower of London, Guy Fawkes, and Anne Boleyn's execution. Izzy explains that Anne Boleyn had a special swordsman from France, and she had to sit up straight for the sword, unlike an axe execution where you put your head down.

Stevie looks at the two buttons on the coffee table. A sequence of things snaps into place. She realizes, “There's no button.” She explains that the button is the point—there is no button. She asks Izzy if she took out the trash. Izzy says it smelled bad, but it's still in the bins out front.

Stevie rushes outside, pulls out the garbage bags, and brings them inside. She digs through the pungent contents with her bare hands. She finds a small slip of paper stained with curry and dotted with bits of rice. She studies it in silence for several minutes. Then she runs upstairs to Angela's bathroom, examines something, and returns to the living room. She asks Izzy to call a family friend who works at the London Eye. “Because I know what happened,” she says, clutching the filthy piece of paper, “and now I have to prove it.”

Character Development

Stevie is at her most determined and vulnerable in this chapter. She's alone, grieving, and running on instinct. Her decision to return to London without support shows her commitment to solving the case, even at personal cost. Her process of deduction is almost physical—she feels a “sizzling” sensation, repeats “seven minutes” obsessively, and yells at the room. This chapter highlights her ability to synthesize seemingly unrelated details (the button, the lock, Samantha Gravis, Anne Boleyn's execution) into a coherent theory. The moment she realizes “there's no button” is a breakthrough, but she's careful not to articulate it fully, fearing she'll lose the thread. Her final action—clutching the receipt and demanding to prove it—shows her shift from passive observation to active pursuit of evidence.

Izzy serves as a grounding presence. She's grieving Angela, but she trusts Stevie completely, saying “I trust you. Do whatever you have to do.” She provides practical help, identifying the buttons and recalling the conversation about Anne Boleyn. Her willingness to sit in the exact spot and recreate the scene demonstrates her faith in Stevie's process. Izzy's role also underscores the theme of family and loyalty—she's not just a witness but an ally.

Doorknob the cat is more than a pet; he's a symbol of hidden truths. His stash of treasures includes the buttons, and his presence seems to guide Stevie's attention. The cat's actions—running around, rubbing against Stevie—mirror the chaotic energy of the investigation.

Themes, Symbols, or Motifs

Grief and Isolation: Stevie's return to London is marked by loneliness. She has no warm bed, no boyfriend, no friends. The house itself feels abandoned, with cold accumulating in corners and quiet leaking everywhere. This atmosphere reflects Stevie's internal state—she's carrying the weight of Angela's death and the mystery.

The Power of Small Details: The chapter emphasizes that truth often hides in overlooked objects: a button, a receipt, a cat's treasure. Stevie's breakthrough comes from noticing what's not there (no sleeping pills, no button) and what is there (the curry-stained slip). The text messages and the seven-minute gap are also tiny details that become crucial.

The Contrast Between Appearance and Reality: Angela's neat, orderly house contrasts with the chaos of the investigation. The buttons seem like evidence but turn out to be red herrings. The receipt, hidden in garbage, is the real clue. This theme reinforces the idea that things are not always what they seem.

Execution Methods: The conversation about Anne Boleyn's execution—sitting up for a sword versus putting your head down for an axe—becomes a metaphor for the different ways people die in the story. It also hints at the method of the killer, as Stevie connects it to the button and the lock.

Why This Chapter Matters

This is the pivotal chapter where Stevie's investigation shifts from confusion to clarity. The realization that “there's no button” is the key that unlocks the entire mystery. It's a classic detective-story moment: the absence of an expected object becomes more significant than its presence. The discovery of the receipt—a physical piece of evidence—gives Stevie something concrete to prove her theory. The chapter ends on a cliffhanger, with Stevie demanding to call the London Eye contact, setting up the climax. It also deepens the emotional stakes: Stevie is acting alone, risking everything, and her grief for Angela fuels her determination.

Study Questions and Answers

1. Why does Stevie conclude that “there's no button”? What does this realization mean for the case?

Stevie realizes that the button Angela mentioned in her text message (“She had the button”) is not a physical object that exists. The button is a metaphor or a code—perhaps referring to a person or a concept. The absence of the button is the point: it means Angela was referring to something else, and the killer's attention was drawn to that message. This realization leads Stevie to look for other evidence, ultimately finding the receipt that will prove what happened.

2. How does the conversation about Anne Boleyn's execution contribute to Stevie's breakthrough?

Izzy's recollection about Anne Boleyn having to sit up straight for a sword execution, unlike an axe execution where you put your head down, triggers a connection in Stevie's mind. It makes her think about the different ways people die and how the method of execution matters. This ties into the lock, the button, and the river deaths, helping Stevie see that the killer's method is consistent with a specific historical or symbolic pattern.

3. What role does Izzy play in this chapter, and how does she support Stevie's investigation?

Izzy is both a practical helper and an emotional anchor. She identifies the buttons, provides the text messages, and recalls the conversation about Anne Boleyn. She trusts Stevie completely, allowing her to search the house and recreate the scene. Izzy's willingness to call the family friend at the London Eye at the end shows her commitment to helping Stevie prove the truth, even though she doesn't fully understand it yet.
