⚠️ 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

It is two o’clock in the morning, and Grace is at the kitchen table sorting through a pile of correspondence. She has a stack of letters that Vanessa wrote to her artist friend Frances Levy; these were returned to Grace after Frances died of Covid. Grace categorizes them into a pile for Becker (the investigator) and a private pile. She reads about Vanessa’s affair with Mark, which broke Mark’s wife Dora, and about Frances’s dismissive comment that Grace is a “hanger-on.” Grace is stung but then finds a letter in which Vanessa defends her, calling her a good friend with a real life. Grace places that letter in Becker’s pile. She also adds a letter mentioning Frances’s children.

Photographs among the papers include a 1999 shot of Douglas and Emmeline Lennox. Grace recalls a weekend when Douglas and Vanessa had sex while Grace helped Emmeline cook stew. The next morning, Grace goes for a walk. She finds a Coke can in the woods and notes the ground is undisturbed in one area. On her return, she meets Marguerite, who has been picking mussels. Marguerite warns that a man was watching Grace from the harbor a few days ago. Grace dismisses it as Becker, but Marguerite is afraid. They have coffee together; Marguerite forgets that Vanessa died and asks where “your friend” is.

After Marguerite leaves, Grace turns to the Carlisle letters – her own correspondence with Vanessa from 2003, the year after Julian Chapman disappeared. She reads her letter offering to return if needed, then Vanessa’s reply: “I don’t want you to come back to Eris. You know things you shouldn’t.” Later there is a note saying “I need you. Please, come.” Finally, Grace looks at shopping lists and a desperate scrap: “please help please you help me grace please help me.”

Character Development

Grace shows her methodical side, her pride in her practical work as a medical professional, and her deep emotional attachment to Vanessa. She is hurt by Frances’s mockery but also capable of vindication. Her decision to save every scrap for Becker reveals both loyalty and a need to control Vanessa’s legacy.

Vanessa appears through her letters as a conflicted figure: capable of cruelty (the affair, the rejection) and of genuine affection (defending Grace). Her later plea demonstrates dependence and vulnerability.

Marguerite is a sympathetic figure suffering from dementia, haunted by an abusive ex-husband. She provides a warning about surveillance and a reminder of the island’s isolated, fragile community.

Themes, Symbols, or Motifs

Preservation and memory: Grace’s obsessive sorting and saving of every letter, sketch, and shopping list mirrors the novel’s interest in how we curate the past for others (especially for Becker).
Art vs. real life: Grace contrasts Vanessa and Frances’s “art voice” with her own hands-on medical work. The letters debate whether art should be relevant; Grace values tangible results over aesthetic pretension.
Secrets and knowledge: Vanessa’s statement that Grace “knows things you shouldn’t” directly ties to Julian Chapman’s disappearance, suggesting Grace holds a dangerous secret.
Isolation and dependence: Grace lives alone on Eris; Marguerite is frightened and forgetful; Vanessa needed Grace at the end. The island setting amplifies reliance on a few people.

Why This Chapter Matters

This chapter provides crucial backstory on Grace and Vanessa’s relationship, especially the fracture that followed Julian Chapman’s disappearance. It reveals that Vanessa once rejected Grace because of what Grace knew, then later begged for her help. Grace’s careful archiving for Becker indicates she may be hiding or shaping evidence. The final desperate plea from Vanessa deepens the mystery of what happened in the months before her death, and what role Grace played.

Study Questions and Answers

1. Why does Grace put some letters in a “private” pile?
She separates letters that contain personal matters—like Vanessa’s affair, Frances’s insult, and references to children—because she intends only the art-related and flattering letters for Becker. She wants to control the narrative Becker will see.

2. What does Vanessa’s 2003 letter to Grace reveal about the aftermath of Julian Chapman’s disappearance?
Vanessa writes that she doesn’t want Grace to return because “you know things you shouldn’t.” This implies Grace possesses knowledge about Julian’s fate that Vanessa finds threatening, suggesting Grace may have been involved in or a witness to something that happened to him.

3. How does Grace’s reaction to being called a “hanger-on” reveal her character?
Grace immediately recalls her medical achievements—saving a fisherman’s hand, diagnosing a child’s cancer—and takes pride in her “real life” and community roots. This shows her deep need for validation and her disdain for the art world, while also highlighting the contrast between her practical worth and the ephemeral art she collected.
