Blood on Her Tongue Questions and Answers

1. Why does Sarah bite Arthur in Chapter 2?

Sarah bites Arthur because the bog‑woman entity inside her perceives him as a threat—offering water when she craves blood. The bite is both a defensive reflex and the first public sign that Sarah’s illness is not ordinary.
Evidence: In Chapter 2, when Arthur tries to give Sarah water, she refuses, accuses him of trying to feed her, then bites his arm. Lucy and Katje restrain her. The scene establishes that Sarah’s “fever of the brain” has a violent, unnatural edge.
Interpretation: The bite foreshadows the entity’s hunger and its hostility toward those who would treat Sarah’s condition with conventional medicine. It also marks Arthur as both a healer and a target.

2. What is the significance of the tick book and Sarah’s marginalia in Chapter 5?

The book on ticks contains Sarah’s deteriorating handwriting, which shifts from scientific observation to frantic comparisons between parasitic fungi and the bog woman. Lucy reads phrases like “like the BOG WOMAN” scratched into the margin.
Evidence: In Chapter 5, Lucy discovers the book with Sarah’s notes. The later entries are smudged and violent, and the final note next to a paragraph about ticks surviving without blood is scrawled: “like the BOG WOMAN.”
Interpretation: The book acts as a window into Sarah’s unraveling mind. The tick becomes a metaphor for the entity that latches onto a host—and Sarah’s own growing awareness that she is being consumed from within.

3. How does Lucy’s erotic fantasy about Michael in Chapter 5 reveal hidden tensions?

Lucy imagines herself as prey in a dark forest, caught by Michael and left with bite‑marks. The fantasy mixes desire and violence, and it ends with her reaching orgasm while thinking of her sister’s husband.
Evidence: After reading the tick book, Lucy cannot sleep and spins a fantasy in which Michael hunts her; she notes that the bite marks would “damn him when I’m found.”
Interpretation: The scene exposes Lucy’s forbidden attraction to Michael and her sense of guilt—she feels she “deserves” to be taken brutally. This desire later fuels her jealousy and complicity in the affair, adding a layer of emotional betrayal beneath the horror plot.

4. Why does Lucy eat a piece of Sarah’s sloughed skin in Chapter 8?

In a moment of grief‑driven compulsion, Lucy swallows a small piece of Sarah’s skin and holds it under her tongue. The act is a desperate attempt to keep a part of her sister with her after death.
Evidence: Chapter 8 describes how Lucy, while sitting vigil over Sarah’s body, picks up a piece of sloughed skin and “swallowed a small piece of Sarah’s sloughed skin, holding it under her tongue.”
Interpretation: This visceral ritual foreshadows the blood‑bond to come. By literally ingesting her sister’s flesh, Lucy prefigures the later arrangement where she will feed the entity—and blurs the line between mourning, love, and the monstrous.

5. What does the broken mirror in Chapter 9 symbolize?

Lucy accidentally breaks a mirror in Sarah’s room. Michael’s violent reaction and his subsequent sexual advance suggest the mirror represents both fractured identity and Lucy’s guilt.
Evidence: In Chapter 9, Lucy breaks the mirror while grieving. Michael enters, rages, then initiates an intimate encounter that leaves Lucy ashamed. The broken glass also reflects the shattering of Lucy’s orderly world.
Interpretation: In folklore, a broken mirror brings bad luck. Here it marks the point of no return: Lucy’s shameful liaison with Michael occurs right after, and her resolve to burn Sarah’s papers—destroying evidence of madness—signals her moral compromise.

6. Why does Lucy agree to Arthur’s proposal condition in Chapter 10?

Desperate to open the coffin in which Sarah is buried alive, Lucy accepts Arthur’s bargain: she will consider his marriage proposal if he helps her unscrew the lid.
Evidence: In Chapter 10, Arthur insists Lucy hear his proposal before he will act. She assents because she believes Sarah is still alive inside the coffin. He then helps her open it, and Sarah sits up.
Interpretation: Lucy’s agreement is a pragmatic survival move, but it also shows her willingness to trade her autonomy for her sister’s life. Arthur’s manipulation reveals a paternalistic control that will later turn deadly.

7. How does the discovery of the golden ring in Chapter 12 connect to the bog woman’s identity?

Mr. Hooiman finds a 17th‑century posy ring engraved “He shall rule over you” near the bog excavation site. The ring leads Lucy and Mrs. van Dijk to the archive, where they uncover the murder trial of Marianne, the bog woman.
Evidence: Chapter 13 describes Mrs. van Dijk identifying the ring as a posy ring with a Latin inscription from Genesis. Later, at the archive in Chapter 14, they find a 1559 court document detailing how a farmer killed his wife Marianne by forcing a rock into her mouth and sinking her in the bog because he believed she was a changeling.
Interpretation: The ring is a concrete link between the historical Marianne and the present horror. The engraving “He shall rule over you” underscores the patriarchal violence that killed the original woman—a theme of female agency crushed by male authority.

8. Why does Lucy copy the court document four times in Chapter 15?

Lucy painstakingly transcribes the 1559 court document four times, as if by memorizing the facts she can control the narrative and somehow cure her sister.
Evidence: In Chapter 15, after reading the court document, Lucy copies it four times. Michael recites a limerick, and Lucy breaks down, wanting her sister.
Interpretation: The obsessive copying suggests Lucy’s attempt to intellectualize the supernatural. She hopes that by knowing the bog woman’s story she can stop the entity. The repetition also mirrors her own entrapment—she cannot stop repeating the role of the devoted twin.

9. What is the significance of the sewing pin test in Chapter 16?

Lucy pricks Sarah’s arm with a sewing pin to test if she is impervious to pain—a trait of the changeling described in the court document. Sarah does not flinch, and black, rotten blood emerges, confirming possession.
Evidence: In Chapter 16, Lucy returns from the archive and finds Sarah engaged in a sexual/blood‑drinking act with Katje. She retrieves a sewing pin, pricks Sarah, and Sarah only notices later. When the pin draws black blood, Lucy screams that she is not her sister.
Interpretation: The pin is a homely tool turned diagnostic weapon. It echoes the historical trial’s methods for identifying changelings and marks the moment Lucy’s denial shatters. The black blood literalizes the corruption within.

10. How does Not-Sarah explain its possession method in Chapter 17?

Not-Sarah tells Lucy that it hibernated inside the bog woman’s corpse, eating her organs to survive. When Sarah cut her hand on the bog woman’s teeth during the autopsy, the entity entered her bloodstream and eventually consumed her consciousness.
Evidence: In Chapter 17, Not-Sarah describes surviving three hundred years in the bog by eating Marianne’s organs, then sleeping. After Sarah cut her hand, the entity “took possession” and absorbed Sarah’s memories.
Interpretation: This explanation recasts vampirism as a biological parasitism rather than demonic possession. The entity is a creature of pure survival, which makes Lucy’s later moral dilemma—feeding it vs. letting it die—more ambiguous.

11. Why does Lucy refuse to kill for Not-Sarah in Chapter 19?

When Not-Sarah demands fresh human meat to heal, Lucy balks, calling murder “horrible, and a sin, and unnatural.” She suggests waiting for an accident, but Not-Sarah argues that neglect is itself murder.
Evidence: The retrieved evidence from Chapter 19 shows Lucy and Not-Sarah arguing about feeding. Not-Sarah insists she needs a whole fresh body, and Lucy cannot commit murder. Katje suggests finding criminals or willing victims, but Lucy rejects that too.
Interpretation: Lucy’s refusal sets up the central moral tension: her love for her sister (or the entity that wears her face) versus her ingrained ethics. She later compromises by letting Not-Sarah feed on Mrs. van Dijk’s severed fingers, showing the erosion of her principles.

12. What triggers Lucy’s decision to kill Michael in Chapter 24?

Michael insists on committing Not-Sarah to an asylum, echoing the fate of Aunt Adelheid, who died in an asylum under suspicious circumstances. Lucy resolves that she will not let history repeat.
Evidence: In Chapter 24, Michael reads a letter diagnosing Sarah with Cotard’s delusion and dismisses Lucy’s fear of asylum death. Lucy remembers Aunt Adelheid’s death and thinks, “I shall kill you first.” She then gouges out Michael’s eyes and stabs him.
Interpretation: Michael’s authoritarian determination to “save” Sarah by institutionalizing her pushes Lucy past her limits. The murder is both a protective act and the culmination of her pent‑up hatred for the man who abused her and her sister.

13. Why does Lucy kill Arthur in Chapter 25?

After Arthur discovers Michael’s body, he proposes framing Not-Sarah for the murder to eliminate her from Lucy’s life. When Lucy refuses, he becomes enraged, shakes her, and reveals his own possessive desire to control her. Lucy grabs a scalpel from his bag and slits his throat.
Evidence: Chapter 25 shows Arthur arguing that Sarah is a “strangler plant” using Lucy. He declares, “It stops tonight,” and reaches for Lucy. She cuts his throat with a scalpel. The retrieved evidence includes her thought, “If you ever think I’d let you hurt my sister, then you don’t know me at all.”
Interpretation: Arthur’s betrayal—he knew Michael abused Lucy—and his attempt to force her into marriage destroy any remaining trust. Lucy kills not just to protect Not-Sarah but to assert her own agency after a lifetime of being used by men.

14. How does the novel use the concept of changeling versus parasite?

The court document calls the bog woman a changeling, but Lucy redefines the entity as “a kind of tick” or parasite. The novel subverts the folkloric changeling into a biological predator that feeds on identity and flesh.
Evidence: In Chapter 17, Lucy calls it “a tick,” and Not-Sarah agrees there is affinity, describing how its kind attaches to a host and feeds. Earlier, the court trial of J.W. (Chapter 14) frames Marianne as a changeling.
Interpretation: By updating the myth, the story critiques how societies label “other” women as non‑human. The parasite is a literal embodiment of that dehumanization—and it forces Lucy to question whether identity survives when memory and body are consumed.

15. What is the ambiguity of Lucy’s final fate in Chapter 27?

The novel ends with a newspaper article reporting Lucy, Not-Sarah, and Katje missing, speculated to have been claimed by the bog. Before that, the sisters and Katje plan to vanish together, with Not-Sarah proposing they eat Michael’s body and sink Arthur in the bog.
Evidence: In Chapter 27, Not-Sarah gleefully drinks Michael’s blood and suggests consuming his whole body. Lucy confesses her affair, and they plan an elopement. The final newspaper article states the three women are missing.
Interpretation: The open ending leaves Lucy’s humanity unresolved. Has she fully joined the parasite’s world? The reader is left to decide whether her loyalty to “Sarah” justifies cannibalism and murder—or whether the bog has claimed yet another woman’s soul.
