⚠️ 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 is alone in Cliff House, reading her mother’s journal. She is deeply shaken by the contents, which hint at a painful past. She imagines her pregnant mother descending to Devil’s Lookout and giving birth in a cave, then abandoning the child. The possibility that the abandoned child was Jess—and therefore not biologically related to Lucy—fills her with anguish. Lucy recalls a night at Jess’s flat in Sydney when she clumsily asked about Jess’s first sexual experience; she now understands that Jess had recently learned the truth of her origins and felt rejected. Lucy wishes she could have handled that conversation with more empathy. Overwhelmed, she is interrupted by a loud knock at the door. A stern voice announces: “Police. Open up.”

Key Events

Lucy finishes a section of the journal and sits in Cliff House’s living room, physically unwell from lack of food and emotional distress.
She visualises her mother at Devil’s Lookout, giving birth alone and abandoning the newborn.
Lucy confronts the possibility that the abandoned baby was Jess, meaning they are not biological sisters.
She reflects on her past conversation with Jess in Sydney, recognising Jess’s defensive reaction as a result of her recent discovery.
Lucy apologises aloud to the empty room, feeling guilt for not understanding sooner.
A police officer bangs on the door, ordering Lucy to open up as rain lashes the house.

Character Development

Lucy: Reaches an emotional turning point. She moves from passive grief to active empathy for Jess, and acknowledges the pain she may have caused by her earlier questions. Her love for Jess is shown to be independent of biology; she insists “they are sisters” regardless of shared blood.
Jess (off-page): Through Lucy’s memories and speculation, Jess’s troubled teenage years take on new context. Her secretive behaviour is now linked to the discovery of her birth story and her isolation.
Mother (off-page): The journal transforms her from a vague presence into a woman who endured trauma in the cave. The chapter humanises her suffering without fully resolving the mystery.

Themes, Symbols, or Motifs

Sisterhood vs. Biology: Lucy’s internal struggle centres on what defines a family. She ultimately affirms that her bond with Jess is not contingent on a shared womb.
The Cave / Womb: The cave at Devil’s Lookout is described as a “red womb,” symbolising both birth and abandonment. It represents hidden female pain and resilience.
Rain and the Sea: The storm outside mirrors Lucy’s internal turmoil. The rain is described as “gunshot loud,” “clattering against her bones,” emphasising her vulnerability.
Memory and Guilt: Lucy revisits her conversation with Jess, wishing for a second chance—a motif of retrospective understanding that runs through the novel.

Why This Chapter Matters

This chapter is the emotional crux of Lucy’s investigation. It confirms the existence of a hidden sister—or a different sister—and forces Lucy to redefine her relationship with Jess. The cliffhanger ending with the police creates urgency and suggests that external forces are closing in. The chapter also deepens the maternal backstory, tying together the novel’s parallel timelines.

Study Questions

Why does Lucy now believe Jess is not her biological sister?
Lucy interprets her mother’s journal to mean that a baby was born in the cave at Devil’s Lookout and then abandoned. She infers that this child was Jess, and therefore they do not share the same mother.
How does Lucy’s perspective on her earlier conversation with Jess change?
She realises that when she asked Jess about losing her virginity, Jess had recently learned her true origins; the question reopened a wound of rejection. Lucy now wishes she had approached Jess with more sensitivity and understanding.
What does the police arrival signify at this point in the story?
It introduces a tangible threat or intervention from the outside world. The police may be investigating Jess’s disappearance, the events at Cliff House, or something related to the journal’s revelations. It marks a shift from introspection to crisis.
