⚠️ 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

Lucy takes the ring from Mr. Hooiman to save him a walk, then brings it to Mrs. van Dijk. After cleaning it, Mrs. van Dijk identifies a posy ring with the Latin inscription Et ipse dominabitur tui (“He shall rule over you”). Katje recognises the phrase from Genesis 3:16. Mrs. van Dijk explains posy rings were exchanged by lovers from the late Middle Ages to the 17th century. Lucy deduces the ring belonged to a Catholic woman because of the Latin inscription and the small size. She plans to show the ring to Michael and visit the local archive to discover the bog woman’s identity, hoping that solving the mystery will cure her sister. Mrs. van Dijk warns Lucy that knowledge does not cure madness and gives her an ultimatum: after the archive trip, Lucy must decide whether to remain as her companion or stay with Sarah.

Themes, Symbols, or Motifs

Knowledge vs. Madness: Mrs. van Dijk argues that learning the bog woman’s story will not cure Sarah, contrasting Lucy’s belief that facts can dispel obsession. This raises questions about the limits of reason.
The Posy Ring as Symbol: The ring’s intimate inscription (“He shall rule over you”) evokes themes of control, submission, and hidden relationships. Its discovery suggests the bog woman may have been bound by love or coercion, echoing Sarah’s own sense of being possessed.
Gender and Authority: Lucy must ask Michael to chaperone her at the archive, highlighting the era’s restrictions on women. Mrs. van Dijk’s authority as employer and older woman also pressures Lucy.
Duty vs. Care: Lucy is torn between her paid role as companion and her unpaid duty as a sister. Mrs. van Dijk’s ultimatum forces a choice between financial security and family loyalty.

Why This Chapter Matters

Chapter 13 provides the first concrete datable clue about the bog woman—a 17th-century posy ring—and narrows the investigation timeline. It also exposes Lucy’s central motivation: she is not merely curious but believes solving the murder will heal Sarah. Mrs. van Dijk’s pragmatic warning introduces doubt about whether knowledge truly conquers madness, setting up a thematic conflict that will likely intensify. Finally, the ultimatum raises the stakes for Lucy’s personal journey, making her next decisions critical for both the plot and her character arc.

Study Questions and Answers

1. What does the inscription on the ring reveal about the bog woman and the person who gave it to her?
The Latin inscription Et ipse dominabitur tui quotes Genesis 3:16, a verse about wifely submission. This suggests the giver expected obedience from the wearer, and because the ring is small and the inscription is in Latin, Lucy reasons the wearer was a Catholic woman. The ring’s style places it in the 17th century, providing a possible time frame for the bog woman’s life and death.

2. Why does Mrs. van Dijk warn Lucy not to pursue the mystery?
Mrs. van Dijk believes that knowing facts about the bog woman will not cure Sarah’s madness. She argues that insanity has no “rhyme nor reason” and that time, not investigation, may heal Sarah. She also fears Lucy’s obsession will harm both sisters and points out that Lucy’s duty as a paid companion is being neglected.

3. How does Mrs. van Dijk’s ultimatum affect Lucy’s position in the story?
Mrs. van Dijk tells Lucy she must choose between remaining as her companion or staying at the estate to care for Sarah. This forces Lucy to confront conflicting loyalties: financial security versus family devotion. It also raises the stakes for the archive visit, as Lucy’s future—and Sarah’s—hinges on what she discovers there.
