⚠️ 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

The chapter opens in the police interview room, where Detective Reyes confronts Irena about the murder weapon. The forensic evidence is damning: blood had dried around the knife on the floor for at least twenty-four hours, Irena's footprints led right past the body to the sink, and the knife had been scrubbed clean and returned to the knife block. Reyes tells her they know it was the murder weapon.

Irena offers a weak denial, then explains she acted out of shock. She says she saw the carving knife on the floor, recognized it as a family piece that had been in the household for decades, and picked it up and washed it out of habit.

Reyes doesn't believe her. He lays out his theory: Irena arrived, found Sheila dead and Fred covered in blood, saw the knife, put on the rubber gloves found under the sink, and scrubbed the knife thoroughly to remove any prints. He believes she was protecting the killer—and that her actions suggest she thinks the killer is one of the children. He warns she could be charged.

Irena remains silent. Reyes then delivers a crucial piece of information: whoever the killer was, they wore gloves, so her interference was unnecessary. Before she leaves, Barr tells her they need her fingerprints for exclusionary purposes.

Irena drives to Catherine's house, dreading the conversation. Ted answers the door, and Catherine and Jenna are waiting. She blurts out an apology and confesses what she did with the knife and that the police now know. Catherine is astonished and angry, asking why she would do such a thing. Jenna answers for her, bluntly: because Irena thinks one of them is guilty. Irena can't meet anyone's eyes. Jenna presses her, asking which one she suspects, but Irena evades the question, apologizing again. The room is charged with tension and dismay.

Meanwhile, Audrey has been watching the police station from the parking lot. She saw Irena leave looking more upset than when she arrived, and watched her sit in her car for a long time as if trying to pull herself together. Audrey briefly leaves her post to use the bathroom and buy a chocolate donut and coffee, then returns in time to see Dan's car pull into the lot. Dan enters the station alone, unaware of her presence.

Dan is brought into the same interview room. Reyes notes his expensive-looking watch and the careless confidence of someone who grew up with money, though Dan seems nervous, fidgeting and clearing his throat. Reyes asks about the sale of Merton Robotics. Dan admits he wasn't happy—he'd worked hard in the company for years expecting it would be his someday, and his father sold it without considering what it meant to him. Reyes sympathizes, and Dan admits his father could be a difficult person.

Reyes then raises Dan's financial difficulty, which Dan doesn't want to discuss. Reyes lays out the motive: a grudge against his father, financial problems, and a very large inheritance. Dan asks if he needs a lawyer. Reyes deflects. Dan rises, says he's not answering any more questions, and knows his rights. Reyes tells him he's free to go but needs to be fingerprinted first.

Character Development

Irena emerges as a deeply conflicted figure. Her decision to clean the knife—whether born of shock, loyalty, or an instinct to protect—has backfired spectacularly. The police now suspect the children, and her confession to Catherine's family has alienated her from the people she was trying to shield. Her inability to meet anyone's eyes and her repeated apologies show a woman who realizes she has made things worse.

Dan Merton reveals more of his resentment toward his father. His admission that he expected to inherit Merton Robotics and felt betrayed by the sale gives the police—and the reader—a concrete motive. His nervousness, fidgeting, and eventual retreat into asserting his rights suggest a man who may be hiding something, or simply a man who realizes how bad things look.

Jenna continues to be the bluntest voice in the family, cutting through Irena's evasions with her direct accusation. Catherine is astonished and angry at Irena's interference. Ted remains a quiet presence, observing.

Audrey shows her persistence, staking out the police station and tracking who comes and goes. Her brief break for a donut and coffee is a small human moment in an otherwise tense chapter.

Themes, Symbols, or Motifs

Family loyalty and its consequences. Irena's decision to clean the knife is an act of loyalty—she wanted to protect whoever killed the Mertons, possibly one of the children she helped raise. But that loyalty has now made the family more suspicious in the eyes of the police.

Suspicion within the family. Jenna's blunt statement—that Irena thinks one of them is guilty—forces the family to confront the possibility that the killer is among them. The tension in Catherine's living room is palpable.

The inheritance motive. Reyes's interrogation of Dan crystallizes the central motive: money. The sale of Merton Robotics, Dan's financial difficulty, and the prospect of a large inheritance create a compelling case against him.

The knife as a symbol. The carving knife, described as a family piece for decades, becomes a symbol of the family's violence and dysfunction. Irena's attempt to clean it—to erase the evidence—mirrors the family's desire to hide its secrets.

Why This Chapter Matters

This chapter significantly narrows the field of suspicion. Irena's tampering with evidence confirms to the police—and to the reader—that someone close to the family is likely responsible. Her confession to Catherine, Jenna, and Ted fractures the family's trust further.

Dan's interrogation establishes a clear motive for him: resentment over the sale of the family business, financial strain, and a large inheritance. While he denies involvement, the pieces are in place for him to become a prime suspect.

The chapter also deepens the mystery of Audrey's role. Her surveillance of the police station suggests she is gathering information, though her purpose remains unclear.

Study Questions

1. Why does Reyes believe Irena cleaned the knife, and what does her action reveal about her suspicions?

Reyes believes Irena scrubbed the knife to remove any fingerprints the killer might have left, protecting the person responsible. He concludes she must suspect one of the children, since she would have no reason to protect a stranger. Her silence when confronted supports this interpretation.

2. What motive does Reyes establish for Dan Merton, and how does Dan respond?

Reyes points to three factors: Dan's grudge against his father for selling Merton Robotics, his financial difficulty, and the large inheritance he now stands to receive. Dan becomes defensive, asks if he needs a lawyer, and refuses to answer further questions before leaving.

3. How does Irena's confession affect the family dynamic at Catherine's house?

Irena's confession shocks and angers Catherine, while Jenna bluntly interprets it as Irena believing one of them is guilty. The family is left in dismay, with Irena unable to meet anyone's eyes. The trust between Irena and the family is severely damaged.
