Complete Chapter Summary

Lucy Goedhart begins her train journey from an unnamed location to the village of Zwartwater, where her twin sister Sarah lives. The morning has been plagued by minor disasters: a horse threw a shoe, delaying her departure, and her boot heel snapped, spraining her ankle. On the train, a fellow passenger dumps luggage in Lucy’s lap, causing her to drop her book and scatter Sarah’s letters. While retrieving them, Lucy is reminded of a childhood memory with her Aunt Adelheid, who showed the twins a worm. Sarah tore the worm in half, leaving Lucy’s piece to die. Lucy internalised this as a metaphor for herself—the weak imitation next to Sarah’s vitality.

A spider appears, and Lucy traps it in an envelope to release later. The passenger kills it with her umbrella. Relieved when the woman leaves, Lucy reads Sarah’s letter. The letter describes the discovery of a bog body on the Schatteleyn property. Sarah details how peat cutters unearthed a naked body staked through the knees, elbows, shoulders, and neck, with a large stone forced into its mouth. Despite the workers’ superstitious fears, Sarah convinced them to continue by offering double pay. She attempted to remove the stone, cutting her hand on the corpse’s broken teeth. She confesses to a “morbid” thought about the body being thirsty rather than hungry. The letter ends with Sarah asking Lucy’s opinion on whether to allow an autopsy.

Disturbed, Lucy looks at her reflection in the train window and is startled by her own gaunt expression, fearing Sarah may indeed be mad.

Character Development

Lucy Goedhart: Her anxiety and sense of inferiority to Sarah are established. The worm memory reveals her long-held belief that she is a “weak imitation” of her twin. She is deeply unsettled by the letter but also loyal, travelling alone despite her fears.
Sarah Schatteleyn: Through her letter, Sarah is portrayed as intellectually curious, brave, and morbidly fascinated. She challenges superstitious workers and insists on scientific study. Her casual confession of a “morbid” thought hints at psychological fragility.
Aunt Adelheid (memory): Shown as eccentric and encouraging of scientific curiosity; her love of insects and worms contrasts with the twins’ differing responses.
Michael Schatteleyn: Sarah’s husband, supportive of the discovery but less emotionally involved; he arranges payment and transport of the body.
Arthur: A doctor eager to perform an autopsy, representing rationalist science.
Mr. Hooiman: The groundskeeper, who advises re-burial and respects local superstitions.

Themes, Symbols, or Motifs

Twinship and Identity: The torn worm symbolises Lucy’s fear that she is the “dead” half—a passive, lesser version of Sarah. The mirror reflection underscores their interchangeability and Lucy’s dread of inheriting Sarah’s supposed madness.
The Bog Body as a Mirror: The ancient corpse becomes a catalyst for both scientific curiosity and supernatural dread. Sarah’s description of its “beautiful” face from certain angles blurs the line between life and death, beauty and horror.
Superstition vs. Science: Workers cross themselves and fear a restless spirit; Arthur and Michael push for autopsy. Sarah occupies a middle ground—she dismisses superstition yet feels an inexplicable connection to the body.
Morbidity and the Female Body: Sarah’s cut hand and the body’s sexlessness (genitals consumed by the bog) echo female bodily vulnerability. The stone in the mouth suggests silencing or forced submission.
Memory and Trauma: Lucy’s childhood worm memory shapes her self-perception. The reader is shown how past events continue to influence present fears.

Why This Chapter Matters

This chapter establishes the central mystery—the bog body—and the twin dynamic that will drive the story. Sarah’s letter presents the first tangible evidence of her deteriorating mental state, while Lucy’s journey physicalises her emotional distance from her sister. The worm memory foreshadows themes of cleavage and loss, suggesting that Lucy may need to face whether she and Sarah are truly separate or dangerously intertwined. The chapter also introduces key secondary characters (Michael, Arthur) and sets up the conflict between rational investigation and superstitious fear.

Study Questions and Answers

How does Lucy’s memory of the worm relate to her view of herself and Sarah?
Lucy remembers that her half of the torn worm died while Sarah’s continued to wriggle. She directly concludes that she is “a weak imitation of the real thing” compared to Sarah. This memory surfaces when letters are scattered, reinforcing her belief that she is the lesser twin—passive, unnoticed, and doomed to be left behind.
What does Sarah’s reaction to cutting her hand on the bog body’s teeth reveal about her state of mind?
Sarah describes the incident as a “strange turn” and admits to a “morbid” fancy about the body being thirsty. She attributes this to the sun and shock, but the casual, almost playful tone in her letter suggests an unsettling fascination with pain and death. This hints at psychological instability beneath her scientific curiosity.
Why does the chapter include the spider incident and the passenger’s violent reaction?
The spider highlights Lucy’s compassion (she carefully traps it to release later) and her composure under minor stress. The passenger’s disproportionate fear and violence contrast with Lucy’s calm, reinforcing Lucy’s isolation and her ability to handle unsettling situations—a trait she will need when confronted with Sarah’s darker experiences.
