Summary

Lucy formally resigns as Mrs. van Dijk’s companion, choosing to stay with her sister instead. After a nightmare in which Sarah consumes her, Lucy wakes to find her period has started. Later, Lucy, Katje, and Not-Sarah discuss Not-Sarah’s urgent need to feed. Not-Sarah recounts the story of Aunt Adelheid, who was imprisoned in an asylum after being diagnosed with hysteria and suffering violent treatments. Lucy learns that Aunt Adelheid may have been a “sapphist” and that her incarceration stemmed from her grief after Vera left. The conversation turns to how to feed Not-Sarah without murder. Not-Sarah argues she must eat a human whole to survive, rejecting grave-robbing or waiting for accidents. Lucy resists the idea of murder, leading to a vicious argument in which Not-Sarah calls Lucy disloyal, spineless, and half a person. Lucy retaliates, calling Not-Sarah a parasite, then storms out, leaving Not-Sarah unable to follow.

Key Events

  • Lucy tells Mrs. van Dijk she is resigning. Mrs. van Dijk forbears but chastises Lucy for stringing her along, and the two part on strained but dignified terms.
  • Lucy suffers a nightmare in which Not-Sarah tears open her belly and feeds on her organs; she wakes to find her period has started.
  • Not-Sarah reveals the truth about Aunt Adelheid: she was committed for “madness,” subjected to humiliating “hysteria cures,” and died in an abusive asylum under suspicious circumstances.
  • Not-Sarah explains her feeding requirements: she must consume an entire, fresh human body to regain strength; small amounts of blood only prolong starvation.
  • Lucy suggests body snatching, but Not-Sarah insists only fresh, healthy flesh works.
  • The argument escalates: Not-Sarah accuses Lucy of not truly loving her, Lucy fires back that Not-Sarah is a parasite.
  • Lucy leaves the room, breaking the emotional stalemate.

Character Development

Lucy shows growth by asserting her own will: she quits her job, stands up to Not-Sarah’s manipulation, and finally voices her resentment about being overshadowed. Yet she is still torn between love and self-preservation. Her nightmare reveals deep anxiety about being consumed—literally and figuratively—by her sister.

Not-Sarah (the entity inside Sarah) displays both vulnerability and cruelty. She is physically desperate and emotionally volatile, using guilt and insults to control Lucy. Her revelation about Aunt Adelheid suggests a trauma that parallels her own experience as a parasite, but she uses it to justify her needs rather than to foster empathy.

Katje remains passive and laudanum-numbed, offering only weak peacemaking. Her character is sidelined, highlighting how the conflict now centers on Lucy and Not-Sarah.

Mrs. van Dijk shows dignity and resignation; her brief scene underscores Lucy’s choice to prioritize family over security.

Themes, Symbols, or Motifs Evidenced

  • Parasitic Relationships: Not-Sarah literalizes the metaphor of a family member draining another. Lucy’s nightmare of being eaten from within mirrors her emotional experience of being consumed by her sister’s needs.
  • Medical Abuse and Historical Hysteria: The story of Aunt Adelheid—diagnosed with hysteria, subjected to “cures,” locked away, and likely killed by the asylum—critiques how society pathologized women who defied norms. The parallel to Not-Sarah’s condition is deliberate.
  • Moral Compromise: The central debate (murder vs. letting Not-Sarah starve) forces each character to confront the limits of loyalty. Lucy’s refusal to commit murder is both principled and potentially fatal for Not-Sarah.
  • Sibling Rivalry and Identity: Lucy’s accusation that Not-Sarah is “only half a person” cuts both ways. The argument reveals that Lucy has long felt diminished in Sarah’s shadow. Not-Sarah’s taunt about Michael reinforces the jealousy and competition that predate the parasite.
  • The Body as Site of Conflict: Period onset, the nightmare of disembowelment, and the discussion of cannibalism all center the physical body as the arena where psychological battles play out.

Why This Chapter Matters

This chapter marks a turning point in Lucy’s arc: she actively resists Not-Sarah for the first time, moving from passive devotion to open rebellion. The revelation about Aunt Adelheid deepens the novel’s commentary on Victorian medical misogyny and connects it to the supernatural horror. The moral dilemma about murder crystallizes the story’s central ethical question: what are we willing to sacrifice for those we love? The argument ends without resolution, leaving the reader uncertain whether Lucy will ultimately help Not-Sarah feed or abandon her.

Study Questions and Answers

1. Why does the nightmare about Sarah eating Lucy mirror the chapter’s real conflict? The nightmare is a symbolic projection of Lucy’s fear that loving Sarah means being consumed—her organs replaced by Not-Sarah’s tendrils. This mirrors the real argument where Lucy feels her identity and autonomy are being devoured by her sister’s demands. The dream’s visceral detail (cold sweat, pain) externalizes Lucy’s emotional dread.

2. How does the history of Aunt Adelheid parallel Not-Sarah’s situation? Both are women who defy social norms: Aunt Adelheid for her “sapphist” tendencies and intellectual pursuits, Not-Sarah for being a literal monster. Both are confined and subjected to medical abuse—Aunt Adelheid by doctors who “cure” her hysteria, Not-Sarah by the threat of being dissected by Arthur and Dr. Rosenthaler. The uncertain circumstances of Aunt Adelheid’s death hint at the violent end that could await Not-Sarah if captured.

3. What does Lucy’s final outburst (“you were a parasite long before one ate your brain”) reveal about her character? It shows that Lucy has been harboring resentment for years, feeling that Sarah (even before the parasite) drained her of independence and opportunity. The accusation reframes their relationship not as loving sisterhood but as a pattern of emotional parasitism. This moment is a breakthrough for Lucy, as she finally gives voice to feelings that previously only surfaced internally.
