Summary

The chapter opens with Cli on the phone with her sister Leda, confessing that their father found a note from the neighbor she hooked up with and shamed her for it. Cli explains that the neighbor left a note saying something like “had fun last night, let’s do it again,” and their dad discovered it while at the house for pest control. Leda scolds Cli for involving their father and for not handling the house herself. Cli defends herself by mentioning dead mice in the garage, stuck in glue traps, including a mouse head with no body. Leda goes silent, then accuses Cli of reading their mother's book, because the dead-mouse detail matches a scene in Demon of Edgewood Drive. Cli denies it, but internally she knows about the priest coughing up half a mouse in the book. She wonders how Leda would know that detail if she never read it.

Leda shifts the conversation to gossip about Holly, a friend in Boston, who is cheating on her husband with her tennis instructor. Cli defends Holly, saying she sees nothing wrong with being selfish. This triggers a vivid memory of her mother sitting on the stairs at Edgewood, after their father had called her selfish. In the memory, her mother tells Cli that men are never called selfish, only women, and that she should take the word as a compliment. But Cli immediately questions whether this memory is real or something she read in the book. She reflects on how the book might be reshaping her memories, contaminating them, or creating false ones.

After the call, Cli sits on the stairs in the same spot her mother supposedly sat. She hears a strange dragging, scraping noise, then a thud. She investigates and finds a jar of peanut butter on the floor, upside down. She puts it back, wondering if she left it on the edge. The noises return, more intense, and the lights flicker and go out. In the dark, she feels hot skin at her fingertips. The lights come back on, and she finds her sketchpad open on the coffee table to a drawing she doesn't remember making, with the word “Hello” written on it.

The chapter then shifts to the mother's manuscript. Alexandra Barnes, the mother, describes a night after Father John's visit. She felt manic and foolish for thinking a holy man could help. She called her sister Helen, telling her she heard noises in the house and that something was laughing at her. She admits she made up parts of the conversation, including details about Rebecca. She reveals that Rebecca was actually a close friend who didn't shun her after the divorce, but she lied about Rebecca not returning calls because she feared telling her about the hauntings would drive her away. She also admits she didn't say “I love you” to Helen, as that wasn't how they were raised. The chapter ends with Alexandra saying that Father Bernard didn't call her; he showed up at the door the next morning with a Bible and a crucifix, and she needed something punchy to end the chapter.

Character Development

Cli is increasingly destabilized. She tries to rationalize the supernatural events, but her fear is visceral and new. She has no fight-or-flight reflex, having lived in comfort most of her life. Her questioning of her own memory—whether the selfishness speech is real or from the book—shows her growing distrust of her own mind. She also shows a defiant streak, defending Holly's selfishness and embracing the label of “slut” as a form of resistance.

Leda is portrayed as risk-averse and judgmental. She gossips only with Cli because Cli doesn't know her Boston friends. She scolds Cli for involving their father and for not handling the house alone. Her accusation about the book is delivered without anger, which makes it more unsettling. She seems to know more than she lets on.

Alexandra Barnes (the mother) is revealed through her manuscript as a deeply isolated woman. She feels like an outsider, pressing her nose to the window of other people's happiness. She lies to her sister about Rebecca, and she admits to fabricating parts of her own story. Her fear of the house and her sense of hopelessness are palpable. She also reveals a bitter awareness of Catholic misogyny, noting that all women are sinners in the church's eyes.

Themes, Symbols, or Motifs

Slut-shaming and sexual double standards are central. Cli's father shames her for a consensual hookup, while her mother's speech highlights how men are never called selfish, only women. Cli reclaims the word “selfish” as a compliment, and she defends Holly's affair.

Memory versus fiction is a major theme. Cli cannot distinguish between a real memory and a scene from her mother's book. The book seems to be contaminating her recollections, making her question whether any memory is trustworthy.

Belief versus delusion is explored through Cli's thoughts about Veronica's butterfly signs and her own fear of the demon. She wonders if delusion is just an eagerness to believe, and she tries to avoid attributing every noise to a boogeyman, but the events become undeniable.

Supernatural haunting is evidenced by the dragging, scraping, laughing, the hot skin, and the sketchpad with “Hello.” The mother's manuscript also describes noises and a priest who fled.

Unreliable narration is present in both Cli's perspective and the mother's manuscript. Alexandra admits she made up parts of her conversation with Helen, and Cli's memory is suspect.

Isolation and loneliness are shown in Alexandra's confession that she lost everyone in the divorce and felt alone. Cli's own isolation in the house mirrors her mother's.

Reclaiming 'selfish' as a compliment is a direct motif from the mother's speech, which Cli tries to adopt.

Catholic misogyny is referenced in Alexandra's thoughts about Eve and the church's view of women.

Book contaminating memory is a specific concern for Cli, as she wonders if the book is creating false memories.

Self-harm ideation is hinted at in Alexandra's manuscript when she tells Helen that the entity wants her to hurt herself.

Why This Chapter Matters

This chapter deepens the mystery of the house and the mother's book. It blurs the line between reality and fiction, both for Cli and for the reader. The supernatural events escalate from mere noises to a physical touch and a written message, confirming that something is actively present. The shift to the mother's manuscript provides crucial context: Alexandra was already experiencing hauntings and had called for help, but the priest left immediately. The revelation that Alexandra fabricated parts of her story forces the reader to question everything in the manuscript, just as Cli questions her own memories. This chapter also establishes the theme of reclaiming selfishness as a form of empowerment, which may be central to Cli's arc.

Study Questions and Answers

1. How does Cli's conversation with Leda reveal the theme of memory versus fiction?

Cli mentions dead mice in glue traps, and Leda immediately accuses her of reading their mother's book because that detail appears in a scene. Cli denies it but knows the book contains a similar incident. Later, Cli recalls her mother's speech about selfishness, but she can't tell if it's a real memory or something she read. This shows that the book is contaminating her memories, making her question what actually happened.

2. What does the mother's manuscript reveal about her reliability as a narrator?

Alexandra admits she made up parts of her conversation with Helen, including saying “I love you” and claiming Rebecca didn't return her calls. She also says Father Bernard didn't call her; he showed up at the door. These admissions show that the manuscript is not a straightforward account—it's a crafted narrative, and the reader cannot trust every detail.

3. How does the chapter use the supernatural to explore Cli's psychological state?

The noises, the hot skin, and the sketchpad with “Hello” are external manifestations of Cli's internal turmoil. She is already questioning her sanity and her memories, and the supernatural events push her to the edge. Her lack of fight-or-flight response suggests she is unprepared for real danger, and the entity's presence forces her to confront the possibility that the house is truly haunted, not just a product of her imagination.
