⚠️ 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

Willow rises early, leaves her son James with Alison, and drives to Maeshowe to meet Perez and Dr Grieve. Inside the Neolithic chamber, George Riley’s body has been forced into a small side chamber, arranged as though for burial. Willow interprets the positioning as a personal, almost revulsive act by the killer. Returning to her house, she and Perez review the ferry passenger list Phil has obtained. Many Westray residents were on the mainland the day Riley died. Willow speculates that Tony Johnson’s academic reputation might have been threatened by Archie’s discoveries, giving motive for both murders. Perez notes ice on Riley’s car windscreen suggests he was killed shortly before Perez arrived. Willow decides to fly to Westray to interview witnesses. Phil meets her at the airstrip, and they first visit Rosalie. Rosalie explains she was in Kirkwall delivering jewellery, then drove to Stromness. Willow presses her about whether she stopped near Maeshowe; Rosalie admits she was tempted but did not stop, claiming she was in a hurry to reach the gallery before closing.

Character Development

Willow: Shows her controlling nature by taking charge despite being on maternity leave. She reflects on her need to stay involved, yet also acknowledges Perez’s feelings. Her scene-mask professionalism contrasts with her private doubts.
Perez: Carries guilt for not meeting Riley sooner. He resists bringing in Glasgow police, preferring local knowledge. His note-taking on paper shows his methodical approach.
Rosalie: Initially calm, but becomes defensive when questioned about her route. Her reference to a “snake in paradise” reveals her fear that the idyllic island community has been violated.

Themes, Symbols, and Motifs

Burial and Desecration: The killer’s placement of Riley in the smaller chamber suggests a symbolic return to a tomb, mixing reverence with violence.
Island as Paradise Lost: Rosalie’s comment about the snake echoes the idea of a once-safe place now corrupted by murder.
Archaeology and Truth: The story stones link the two murders; the investigation centres on whether academic dishonesty around them drove the killings.
Movement and Opportunity: The ferry passenger list becomes a key tool, highlighting how the islands’ transport network creates alibis and opportunities.

Why This Chapter Matters

This chapter tightens the connection between Archie’s and Riley’s deaths, introducing a plausible motive tied to Tony Johnson’s archaeological research. Willow’s decision to lead the Westray interviews advances the investigation and reveals Rosalie’s possible involvement. The emphasis on timings (windscreen ice, ferry sailings) narrows the window for the killing, while Willow’s character is deepened through her struggle between maternal duty and professional drive.

Study Questions and Answers

1. Why does Willow think the killer placed Riley’s body in the small side chamber of Maeshowe? She believes the action was not an attempt at concealment but rather a visceral revulsion—pushing the body away, as if the killer felt a need to dispose of it with a personal, violent gesture.

2. How does Perez use the condition of Riley’s car windscreen to estimate the time of death? He notes that the extreme cold froze his own windscreen after an hour. Riley’s windscreen was clear when Perez saw it at the mill, suggesting the car had not been parked there long before he arrived, putting the death shortly before his visit.

3. What is Rosalie’s explanation for being on the mainland, and why does Willow question whether she stopped at Maeshowe? Rosalie says she delivered jewellery to a Kirkwall shop and then drove to Stromness to visit a gallery. Willow points out that the main road passes the Maeshowe footpath; Rosalie admits she was tempted to stop but says she did not, though her hesitation makes her a potential witness.
