Summary

On Saturday, 16 February 2019, Lucy is inside Cliff House when police arrive. She freezes, convinced they have come to report that Jessica’s body has been found. She imagines her sister at the bottom of a cliff, washed up by the sea. The officers knock impatiently, and Lucy forces herself to open the door. Two officers—a man and a woman in fluorescent rain jackets—enter and sit on the couch, moving aside Jess’s diary and a blanket. Lucy stands before them, bracing for the news that Jess is dead.

The female officer asks if she can call Lucy “Jessica.” Lucy’s panic lifts when she realizes they are looking for Jess, not reporting her death. She identifies herself and asks if Jess is okay. The officers explain they are investigating a case involving Cameron Hennessey, Jess’s former partner. His car was found nearby, and they need to question him. They ask when Lucy last saw her sister; Lucy confesses she has not seen Jess in over a year and arrived unannounced on Tuesday to find Jess gone. Neighbor Melody said Jess had left.

The male officer asks if the name Cameron Hennessey means anything to Lucy. Lucy lies, saying no, though she knows the name from Jess’s diary. The officers leave a card and depart as thunder crashes. After they go, Lucy examines her feet and notices the skin between her toes is thicker and webbed. She peels off a scaly patch to reveal a bluish layer. Lucy realizes Jess might have run away with—or from—Cameron.

Character Development

Lucy experiences a surge of terror when the police arrive, revealing her deep fear that Jess is dead. Her relief when she learns Jess is still missing is followed by anxiety about what Jess might have done. Lucy’s instinct to protect Jess (“that instinct for the truth”) competes with her need to lie when asked about Cameron Hennessey. Her physical transformation—webbed toes—intensifies, linking her psychological state to the novel’s themes of metamorphosis. The chapter shows Lucy becoming increasingly entangled in Jess’s secrets and her own bodily changes.

Jessica remains absent but looms large through the police investigation. The officers’ questions suggest Jess may be involved with a man of interest to the police, deepening the mystery of her disappearance.

Cameron Hennessey is introduced as a suspect or person of interest. The image of his car found nearby implies he and Jess may be together—or that something violent has occurred.

Themes, Symbols, or Motifs

Transformation and the Sea: Lucy’s webbed feet and bluish skin evoke marine life, symbolizing her gradual shift away from humanity. The sea is described as an animal rejecting its young, reinforcing a motif of alienation and unnatural change.

Truth vs. Lies: Lucy lies to the police about knowing Cameron, choosing loyalty to Jess over honesty. Her internal conflict highlights the novel’s exploration of secrets and self-preservation.

The House as a Character: Cliff House’s decay—mould, tarp-covered hole, clutter—reflects Jess’s troubled life and Lucy’s own instability. The officers’ disgusted glances emphasize the house’s isolating, oppressive atmosphere.

Police Investigation as a Catalyst: The arrival of authority figures forces Lucy to confront her sister’s disappearance and her own complicity in hiding the truth. The investigation raises stakes and introduces external conflict.

Why This Chapter Matters

This chapter transforms the novel’s central mystery from a personal disappearance to a police investigation, raising the stakes and introducing a new suspect, Cameron Hennessey. Lucy’s lie demonstrates her commitment to Jess despite the risk, and her physical changes accelerate, linking her transformation directly to Jess’s world. The chapter also reveals that Jess’s absence is more deliberate than accidental, and that Lucy’s own past (Ben, her reasons for coming) remains unresolved.

Study Questions and Answers

Why does Lucy initially think the police are there to report Jess’s death?
Lucy has been living with anxiety and guilt about her sister. When she hears the knock, her mind immediately jumps to the worst-case scenario, imagining Jess’s body found at sea. This reaction stems from her fear that she failed to act in time.
What does the officers’ visit reveal about Jessica’s situation?
The officers are looking for Cameron Hennessey, Jess’s ex-boyfriend, and suspect Jess may be with him. This suggests Jess is either entangled in an investigation or has left voluntarily with Cameron. The mention of “reasonable cause” and “suspect” indicates something serious—possibly a crime—has occurred.
How does Lucy’s physical transformation relate to the events of this chapter?
After the police leave, Lucy notices her toes have become webbed and bluish, echoing earlier hints of change. This transformation parallels her psychological shift: lying to protect Jess and facing the police push her further from normal human experience, aligning her with the sea and the novel’s mythical elements.
