Summary

The chapter opens with the narrator concealed in a hidden passage inside the library, listening as Detectives Cates and Pilar de León begin questioning Fergus Barnes. Pilar's soothing tone contrasts with Cates's more direct approach, and the narrator notes how tightly wound Fergus appears.

Cates asks why Fergus came to Ashwood Manor. Fergus explains that Kassidy invited him, but the real reason was that Blaine had begged him to come for moral support. Blaine intended to break up with Kassidy at the end of the week, and he wanted his best friend nearby. This revelation hits the narrator hard: a ripple of nerves travels up the narrator's back, followed by a wave of guilt nearly overwhelmed by relief. The narrator reflects that the gold knife ended that threat forever—a chilling admission that confirms the narrator is the killer.

Fergus continues, describing Blaine's recent behavior. Blaine had been acting strangely all semester, disappearing for hours after school and ignoring texts. Fergus suspects Blaine was hooking up with someone he hadn't mentioned. When Cates suggests Chloe Li, Fergus dismisses the idea, saying he knew about Chloe and that Blaine must have been embarrassed by the other girl. The narrator cringes at how well Fergus knows Blaine.

Cates then asks about Fergus's whereabouts before cocktail hour. Fergus says he was walking in the pine forest, but admits no one can confirm his alibi. He describes the evening: cocktails in the drawing room, the butler calling them to dinner, Kassidy going to fetch Blaine, and everyone running upstairs when they heard her scream. Fergus notes that Izzy reached Blaine's room first, moving so fast it seemed like she expected the scream, and that Ellison reached the body first. The narrator bristles at Fergus's implied criticism of Izzy's speed, remembering a time the narrator sprinted to help Fergus at Winter Formal.

Fergus grows emotional, describing Blaine's childhood personality: a big, fun, adventurous kid who pushed Fergus to do reckless things—jumping off high diving boards, riding bikes down steep hills, even stealing money to buy cigarettes. Fergus laughs at the memory, but the mood shifts when Cates asks about drugs. Fergus initially denies that Blaine sold drugs, insisting Blaine didn't need money because his father paid generous child support. The narrator recognizes Fergus's lie, noting that if Fergus is lying, then Marlowe was telling the truth about Blaine being a drug dealer.

Pilar de León gently reframes the question, explaining they only want to establish a motive. Fergus, desperate to pin the murder on an outsider, backtracks and admits Blaine sometimes sold pills to students. He frames it as a public service, citing the stress of Marian and how the drugs helped people study or take the edge off.

After Fergus leaves, Cates mutters with disgust that rich kids always frame dealing drugs as a public service, revealing that his own cousin has been in jail for five years for selling a few ounces of weed. The narrator shifts uncomfortably in the cramped passage, both feet asleep and knees throbbing, and wonders about the legality of eavesdropping on police interviews. But the narrator decides the risk is worth it, needing to hear everything everyone tells the detectives. Cates announces that two interviews remain.

Character Development

The Narrator: This chapter delivers the book's most significant reveal—the narrator is the killer. The narrator's internal monologue shows a calculating mind: guilt and relief intertwine as the threat of Blaine's breakup plan is neutralized. The narrator also displays vanity and resentment, bristling at Fergus's comment about Izzy's speed while remembering a past moment of heroism. The decision to continue eavesdropping despite the legal risk shows the narrator's determination to control the narrative.

Fergus: Fergus emerges as a grieving but unreliable witness. He lies about Blaine's drug dealing initially, then backtracks when the detectives frame it as motive. His desperation to blame an outsider makes him pliable in Pilar's hands. His childhood memories of Blaine reveal a deep friendship, but his inability to act convincingly—the narrator notes he can't lie his way out of a paper bag—makes him a weak link in the investigation.

Detective Cates: Cates's comment about his cousin's imprisonment reveals a personal stake in class disparity. His disgust at Fergus's framing of drug dealing as a public service shows his awareness of how wealth shapes justice.

Pilar de León: Pilar's soothing, therapist-like approach proves effective. She senses Fergus's tension and uses gentle reframing to extract the truth about Blaine's drug dealing, demonstrating sharp investigative instincts.

Themes, Symbols, or Motifs

Eavesdropping and Surveillance: The narrator's hidden position in the passage symbolizes the broader theme of secrets and hidden truths. The narrator is both observer and participant, gathering information while concealing their own guilt.

Guilt and Relief: The narrator's conflicting emotions—guilt over the murder, relief that Blaine's breakup plan is thwarted—reveal the psychological complexity of the killer. The gold knife becomes a symbol of the irreversible act that binds the narrator to the crime.

Class Disparity: Cates's comment about his cousin's imprisonment versus Fergus's framing of drug dealing as a public service highlights how wealth and privilege shape perceptions of crime and justice.

Deception: Fergus's initial denial about Blaine's drug dealing, the narrator's hidden presence, and Blaine's secret relationship all underscore the theme of deception. Everyone is hiding something.

Motive: The chapter establishes two potential motives: Blaine's planned breakup with Kassidy and his drug dealing. Both point to different suspects, complicating the investigation.

Why This Chapter Matters

This chapter is a turning point in the novel. It confirms the narrator as the killer, a revelation that reframes every previous scene. The narrator's internal admission—that the gold knife ended the threat of Blaine telling Kassidy everything—suggests the murder was premeditated and tied to a secret the narrator needed to protect. The chapter also introduces Blaine's drug dealing as a potential motive, giving the detectives (and readers) an alternative suspect pool. Fergus's testimony about Blaine's secret relationship adds another layer of mystery, while Cates's personal comment about his cousin deepens the novel's social commentary. With two interviews remaining, the chapter sets up the next phase of the investigation, raising the stakes for the narrator, who must continue to listen and adapt.

Study Questions and Answers

1. What does the narrator's reaction to Fergus's testimony reveal about the murder?

The narrator's internal admission—feeling guilt nearly overwhelmed by relief upon learning Blaine planned to break up with Kassidy—confirms the narrator is the killer. The gold knife reference ties the narrator directly to the crime. The relief suggests the murder was motivated by a need to prevent Blaine from revealing something, likely connected to Kassidy.

2. How does Fergus's testimony about Blaine's drug dealing complicate the investigation?

Fergus initially denies Blaine sold drugs, then admits it after Pilar reframes the question. This creates a second potential motive for the murder: someone connected to Blaine's drug dealing could have wanted him dead. It also validates Marlowe's earlier claim, making Marlowe a more credible witness. The detectives now have two competing motives to investigate.

3. What does Detective Cates's comment about his cousin reveal about the novel's themes?

Cates's remark—that his cousin has been in jail for five years for selling a few ounces of weed—highlights the class disparity in how drug crimes are treated. Fergus frames Blaine's dealing as a public service, while Cates's cousin faced severe consequences. This contrast underscores the novel's critique of wealth and privilege, showing how the same actions are judged differently based on social status.
