⚠️ 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
After finishing a historical court document, Lucy feels sick and chilled. The document records a husband’s testimony about his wife Marianne, whom he murdered because her strange behaviors—spooking animals, knowing things she should not, showing unnatural appetites, being impervious to pain, and smelling like a corpse—convinced him she was a changeling. Lucy immediately sees that Sarah has exhibited many of these same symptoms: animals fear her, she lacks appetite, has begun cursing, and seems changed. Though Lucy initially tries to dismiss the parallels as coincidence, the weight of evidence forces her to accept that Sarah may not be her sister.
She copies the document four times: for Arthur, the university, Michael, and herself, tucking the last copy into her pocket. Michael recites a vulgar limerick he claims to have found in a pamphlet, but Lucy suspects he made it up. She becomes tearful, overwhelmed by love for her twin despite Sarah’s current state. On the drive back to Zwartwater, she longs to see Sarah.
When she returns, Lucy rushes to Sarah’s room without knocking. She finds Sarah in bed with Katje, who is drugged and in pain from her womb. Sarah is performing oral sex on Katje; her face is smeared with blood. Lucy is shocked and retreats. In her own room, she re-reads the court document and fully acknowledges that something has taken possession of her sister. Determined to confront it, she takes a long pin from her sewing kit to test whether the entity is impervious to pain. She goes to Sarah’s room and knocks.

Character Development
- Lucy: Moves from denial to reluctant acceptance of a supernatural explanation. Her love for Sarah drives her to confront the entity, but she is also jealous and humiliated by being ignored during the intimate scene. She shifts from passive observation to active planning, taking a pin as a tool for proof.
- Sarah (the entity): Revealed to be sexually aggressive, consuming blood, and indifferent to Lucy’s presence. Her behavior aligns with the bog woman’s description, reinforcing the changeling/possession theory.
- Michael: Shows a lighthearted side with his limerick, but Lucy’s memory reveals a history of resentment over his jealousy of Sarah’s intelligence. He remains unaware of the deeper horror.
- Katje: Passively participates while drugged, her role as an invert and her attachment to Sarah complicate the scene. She is a victim of both her condition and the entity’s appetite.
- Mrs. van Dijk: Limited to the archive scene, where she assists Lucy and confirms the document’s relevance.
Themes, Symbols, or Motifs
- Changeling Folklore: The court document directly invokes the belief that a changeling replaces a human. This chapter forces Lucy to consider that Sarah has been replaced by the bog woman.
- Blood and Appetite: Sarah’s mouth is smeared with blood, linking her to the bog woman who had a stone in her mouth. The act of “drinking” blood suggests a parasitic or vampiric hunger.
- Madness as a Tool: Lucy notes that once a woman is deemed mad, any behavior can be dismissed as a symptom. She fears being labeled mad herself if she reveals the truth.
- Evidence vs. Belief: Lucy struggles to trust her logical mind against mounting supernatural evidence. Her decision to test with a pin shows she now seeks physical proof.
- Sexuality and Power: The scene with Katje blends desire, dominance, and blood consumption, subverting Victorian expectations of female passivity. Sarah’s role is aggressive and consuming.
Why This Chapter Matters
This is the turning point of the novel. Lucy abandons rational explanations and fully accepts a supernatural cause for Sarah’s condition. The discovery of the bog woman’s identity provides a concrete historical link, while the intimate scene with Katje confirms the entity’s unnatural appetites. Lucy’s preparation of the pin sets up a direct confrontation, raising the stakes for the next chapter. The chapter also deepens Lucy’s emotional complexity: she loves Sarah fiercely yet feels wounded by her rejection.
Study Questions and Answers
-
Why does Lucy initially reject the idea that Sarah is a changeling? Lucy is a rational thinker who believes changelings belong to superstition or madness. She prefers to attribute Sarah’s behavior to her near-burial and recovery. Only the accumulation of specific parallels from the court document forces her to reconsider.
-
How does the scene with Katje and Sarah challenge Lucy’s understanding of her sister? Lucy sees Sarah engaged in a sexual act that is both intimate and violent, with blood on her face. The entity ignores Lucy entirely, making her feel insignificant. This challenges Lucy’s image of Sarah as her twin and confidante, suggesting the entity has no connection to her.
-
What does the pin symbolize in Lucy’s plan? The pin represents Lucy’s shift from passive observation to active intervention. It is a tool to test imperviousness to pain, the trait that the husband noted in Marianne. The pin also connects to the sewing kit Sarah made for her, linking Lucy’s childhood to her current desperate measures.
