Summary

Sebastian leads David and Stevie on a private tour of his estate, Merryweather. He explains that his family has owned the land since 1675, though he shows little reverence for the history, noting that the current house is a replacement built after two earlier structures were torn down. He reveals that the estate now earns its keep by hosting weddings, events, and film shoots, and that he sometimes works as an extra—once playing a butler with a single line. He mentions his husband, an antiques expert for Sotheby's, who is currently in Vienna appraising items for an auction. Stevie casually asks when the husband left, and Sebastian says last week.

As they walk, Sebastian warns Stevie about a ha-ha—a sunken garden wall designed to keep animals out without interrupting the view. He then points out a fly agaric mushroom, noting its mild psychoactive properties, and then a death cap mushroom, which he describes as deadly and unassuming. He says, “It’s always the quiet ones,” a phrase that lingers with Stevie.

They pass through elaborate gardens designed by his great-grandfather, and Sebastian explains that he partners with an addiction recovery organization, hosting retreats at the estate. He hopes to turn it into a residential treatment center once repairs are complete.

Stevie takes the opportunity to ask about Angela. Sebastian insists Angela wouldn't vanish without telling anyone, and he shows Stevie the text chain from the night of the murder—the same chain Stevie has already seen. Stevie asks about the “button” reference, but Sebastian dismisses it as an autocorrect. He says he last saw Angela at a party at Peter's house a few weeks earlier, where she seemed utterly normal. He left early with Theo.

Sebastian then opens up about his own past. He describes his father, the fifth viscount, as a “bastard” who rejected him for being gay. In response, Sebastian embraced a flamboyant, reckless lifestyle, drinking heavily and using drugs. He studied chemistry at Cambridge but deliberately did the bare minimum to pass, aiming for the lowest grade. After the events of June 1995, he moved to London and spiraled into addiction, eventually ending up in a hospital after a near-fatal overdose. His friends—especially Theo—helped him get clean, and he has remained sober ever since. He reflects that the murder “broke” all of them in some way, and that they remain each other's most important people.

Sebastian then leads them to the woodshed—the site of the murder. He says he can't bring himself to tear it down. The shed is larger than it appears in photos, with a new door and a simple key lock. Inside, it holds a rider mower and hay bales. Stevie notices the ceiling is flat, lower than the building's exterior suggests, implying a crawl space above. She spots a rope pull and asks what's up there. Sebastian says it's just a crawl space, and when Stevie suggests that's where the robbers hid, he insists no one could have—the floor was rotted away and his parents sealed it up. He adds it was later replaced for safety.

Stevie asks to take photos for a school assignment, and Sebastian leaves her and David alone. Stevie closes the door, and with David's help, they pull down the folding ladder and climb into the crawl space. It's a low, dusty space with a small window. Stevie compares photos on her phone: Sooz's photo from the night of the murder shows the window closed, but a police photo from the next day shows it open. She also notices that in a crime scene photo of the ceiling, the rope pull is missing. She concludes that someone accessed the crawl space after the murder—contradicting Sebastian's claim that it was inaccessible. David suggests the police might have opened the window, but Stevie points out that the police reports never mention a crawl space, and they wouldn't have opened a crime scene window and then photographed it. She deduces that the police never knew the space existed.

David asks what this means, and Stevie says it means the crawl space and the window matter. She suggests Sebastian may have lied about the rotted floor. David notes that Sebastian was the one person everyone could see the whole time, so why would he lie? Stevie doesn't have an answer, but as they head back inside, she remarks that they may have left their friends with a murderer.

Character Development

Sebastian emerges as a complex figure. He presents himself as a reformed hedonist, openly discussing his addiction and recovery. His decision to keep the woodshed—despite its dark history—suggests a need to confront the past rather than erase it. Yet his claim about the crawl space being inaccessible is directly contradicted by the evidence Stevie finds, casting doubt on his honesty. His earlier comment about the death cap mushroom (“It's always the quiet ones”) takes on new weight, hinting that he may be more dangerous than he appears.

Stevie demonstrates her detective instincts by noticing the discrepancy between the ceiling and the building's height, and by carefully comparing photos. She uses the tactic of “tell it wrong” to elicit information from Sebastian, showing her growing skill at manipulation. Her final line—about leaving their friends with a murderer—reveals her suspicion has shifted toward Sebastian, even as she lacks a motive.

David provides support and comic relief, but also serves as a sounding board. His question about why Sebastian would lie highlights the logical problem: Sebastian was visible the whole time, so why would he need to lie about the crawl space? This uncertainty deepens the mystery.

Themes, Symbols, or Motifs

Hidden spaces: The crawl space is a literal hidden space, but it also symbolizes the secrets the characters keep. Sebastian's claim that it was sealed mirrors his own attempts to control the narrative.
Deception: Sebastian's lie about the rotted floor—if it is a lie—underscores the theme of deception that runs through the novel. The text chain, the missing rope, and the open window all point to deliberate concealment.
Ordinary as deadly: The death cap mushroom looks harmless but is lethal. The woodshed is an ordinary outbuilding, yet it's the site of a murder. This motif suggests that danger often hides in plain sight.
Trauma and recovery: Sebastian's backstory shows how the murder fractured the group, leading him to addiction and eventual recovery. His work with addiction retreats indicates a desire to heal others, but his possible deception complicates that image.
Past's persistence: The woodshed remains standing, and Sebastian refuses to tear it down. The past is not easily erased; it lingers in physical spaces and in the minds of the survivors.
Opened window clue: The window's change from closed to open is a crucial clue, suggesting that someone revisited the scene after the murder. It points to a deliberate act, not an accident.
Quiet ones: Sebastian's phrase about the death cap mushroom echoes the idea that the most unassuming people or things can be the most dangerous. This could apply to Sebastian himself, or to another character who seems harmless.

Why This Chapter Matters

This chapter is pivotal because it introduces a concrete piece of evidence that challenges the official narrative. Stevie's discovery of the crawl space and the open window suggests that the murder scene was tampered with after the fact. If Sebastian lied about the crawl space being inaccessible, it raises the possibility that he—or someone else—used that space to alter the scene. The chapter also deepens Sebastian's character, making him a more plausible suspect while leaving room for doubt. The final line, “I think we may have left our friends with a murderer,” raises the stakes and sets up the next chapter's tension.

Study Questions and Answers

Why does Stevie suspect Sebastian lied about the crawl space?

Stevie notices that the ceiling is flat and lower than the building's exterior, indicating a crawl space. When she asks about it, Sebastian says the floor was rotted and sealed. But after climbing up, she finds the window was closed in Sooz's photo from the night of the murder, yet open in the police photo from the next day. She also sees that the rope pull is missing in the crime scene photo. Since Sebastian claimed no one could access the space, the only explanation is that he was lying—or that someone else accessed it without his knowledge. 2. What does Sebastian's backstory reveal about his relationship with the other members of the Nine?

Sebastian describes how the murder “broke” all of them, and how he hit rock bottom before his friends helped him recover. He says they are still the most important people in each other's lives. This suggests a deep bond, but also a shared trauma that might motivate them to protect each other—or to hide the truth. His comment that Julian is a “textbook politician” and that Yash has been pining for someone for years hints at unresolved tensions within the group. 3. How does the death cap mushroom function as a symbol in this chapter?

Sebastian points out the death cap mushroom and says, “It's always the quiet ones.” This phrase connects to the woodshed itself—an ordinary, unassuming building that hides a violent history. It also foreshadows the idea that someone who seems harmless—perhaps Sebastian himself—could be deadly. The mushroom's innocuous appearance mirrors the way the truth about the murder may be hidden in plain sight.
