Character Development

Grace: Her guilt deepens as she confronts her past failure to act on signs of Marguerite’s abuse. She is also physically and emotionally drained, struggling with headaches and wine consumption. Her decision whether to involve social services reveals her protectiveness versus her fear of government intervention. Marguerite: Physically frail and mentally declining, she blends past and present. Her memory selectively retains her abusive husband while erasing a later happy relationship. Her whispered fear and the deal she offers (“You do something for me, I do something for you”) hint at buried secrets. Stuart (mentioned): Remains an off-page menace, defined by enormous hands and violent control. Nick Riley (briefly recalled): His arrival “staggered” Grace, suggesting a fraught personal history.

Themes, Symbols, or Motifs

Memory and Forgetting: Marguerite’s inability to remember her kind later partner while remaining haunted by her abuser underscores how trauma can warp memory. The island’s lack of memory contrasts with human scars.
Domestic Abuse: The chapter revisits Grace’s complicity in ignoring bruises that “did not explain” the fingerprint-shaped marks. Marguerite’s insistence on “c’est vrai” reflects years of covering up violence.
Guilt and Responsibility: Grace blames herself for being distracted and not pressing Marguerite further. Her hesitation to call social services shows her conflicted sense of duty.
Storms as Metaphor: The literal storms that reshaped the island parallel the destructive events in people’s lives – Julian’s disappearance, Marguerite’s marriage – leaving “scars” visible only to those who remember.

Why This Chapter Matters

This chapter provides critical backstory on Marguerite, linking her to the island’s history and to Grace’s past as a doctor. It exposes Grace’s moral failure and suggests that unresolved issues from years ago may connect to present mysteries, including Vanessa’s arrival and Julian’s disappearance. The final reference to Vanessa’s scars ties Marguerite’s story to the larger plot, raising questions about what Grace might have missed in other cases.

Study Questions and Answers

1. Why does Grace feel guilty about her first encounter with Marguerite?
Grace saw fingerprint-shaped bruises on Marguerite’s neck and arms but accepted her story of a fall because she was distracted by Nick Riley’s sudden arrival. She now believes she should have asked more questions and reported the abuse.

2. What does Marguerite mean when she says “L’isle ne se souvient pas”?
She means the island does not remember – unlike people, the landscape lacks memory of past events. Grace interprets this as a meandering riddle, but it underscores Marguerite’s own decaying recollections and the idea that past trauma is not recorded by the environment.

3. How does the chapter contrast Marguerite’s two relationships?
Marguerite fixates on Stuart, the abusive husband, while having entirely forgotten the gentle farmer she loved after Stuart went to prison. Grace finds this cruel – that fear of the brute survives while happiness fades.
