(If you're caught up, continue below.)
Summary
The chapter opens with Samuel returning to his home in Enfield after four days away. He reflects that his house, once perfectly satisfactory, now feels inadequate after seeing the grand properties connected to the case—he at least needs a new kitchen. He unpacks groceries from Tesco: fresh pasta, broccoli, garlic, and a large tomato, planning a vegetarian meal. He explains his eating habits: he tries to eat meat only once a week, for the planet and for the animals, though he sometimes craves a chicken salad sandwich or a charred burger.
The narrative then shifts to the afternoon's events. Samuel and his colleague Donal had confronted Libby Jones about her bank transactions. They knew she had given away two-thirds of her inheritance, and they pressed her for an explanation. Libby, with flushed cheeks, claimed that Marie Caron and Phineas Thomson were her friends, that they were on holiday without their phones, and that she had given them the money out of generosity. Samuel found this implausible, especially when she admitted they hadn't invited her to join them. He then asked about the graffiti in the house on Cheyne Walk that read “I AM PHIN.” Libby claimed not to have noticed it, and Samuel pointed out the coincidence that this unusual name matched her “very, very good friend.” He also asked why she was staying at Dido's house instead of her own flat, and she said she wanted to let the dog run in Dido's garden. Samuel concluded that it was all lies and planned to bring her to the station the next day for a more formal interrogation.
Back at home, Samuel makes his pasta and watches a detective show, noting that he enjoys them even when they get details wrong. Around nine p.m., he receives a message from Philip Dunlop-Evers, Birdie's relative, asking for updates. Samuel replies that there are no firm updates yet but that tomorrow promises much news: they have a possible last-known address and are trying to track down two people who may have lived in the house when Birdie died.
In the shower, Samuel mentally reviews the case as a three-dimensional sphere, looking for holes and trying to fill them. He recaps what he knows: Birdie Dunlop-Evers, a young woman in the late eighties, lived temporarily in a large house owned by Henry and Martina Lamb, who had three children: Henry Jr., Lucy, and Serenity. Samuel notes the oddity of the children's names—the first two traditional, the last bohemian—and wonders if the cult they died for influenced that choice. Birdie was killed by a blow to the head, mummified in expensive towels, and hidden on a rooftop for years before her remains were thrown into the Thames, likely after Libby inherited the house. Around the same time, Henry and Martina poisoned themselves on the kitchen floor alongside a mysterious man with initials DT. Shortly after, two to six teenagers fled the house and were never seen again. Two were likely Henry and Lucy Lamb; another might be the “PHIN” from the graffiti.
Samuel then has a breakthrough: he connects “Phin Thomson” to the initials DT, theorizing that DT could be Phin's father. He assumes Phin was also resident in the house at the time of Birdie's death and is now in receipt of £2.48 million from the house sale. He turns his attention back to Birdie, remembering she arrived at Cheyne Walk with a boyfriend, Justin Redding, a percussionist. No trace of him was found, and no one remembered seeing him. Samuel considers whether Justin was still there when Birdie died, and despite others' belief that Justin was too soft to be involved, Samuel sees him as a likely culprit. He decides they need to find Justin Redding, who could be the key to everything.
Finally, Samuel thinks about Libby's dog. He recalls her physical tells when she explained the dog's ownership, and he wonders if the dog doesn't belong to her adoptive mother in Spain. If not, then Libby has another person she considers a mother—possibly Marie Caron, the female beneficiary of a third of her inheritance. Could Marie Caron be another of the disappeared teenagers? Samuel's mind loops around the sphere, but he feels he has enough for now. He sets his alarm for five a.m., knowing he has much to do.

Character Development
Samuel emerges as a methodical and intuitive investigator. His personal reflections on his home and eating habits humanize him, showing a man who is both ordinary and deeply engaged in his work. His mental “sphere” metaphor reveals his systematic approach to problem-solving—he visualizes the case as a complete world and seeks to fill its holes. His willingness to challenge Libby's lies and his determination to pursue Justin Redding demonstrate his persistence. The chapter also shows his empathy, as he thinks about the turkeys he's seen on the internet, even while acknowledging his own lapses.
Libby Jones is portrayed as evasive and deceptive, though her lies seem to stem from a need to protect someone or something. Her flushed cheeks and implausible explanations suggest she is not a skilled liar, but she is resolute. Samuel's assessment that “it was all lies” underscores her role as an obstacle to the truth.
Philip Dunlop-Evers appears briefly as a concerned relative, seeking updates and trusting Samuel's assurances. His presence reminds us of the human stakes of the case.
Themes, Symbols, or Motifs
-
Deception and Lies: The chapter is saturated with lies—Libby's fabrications about her friends, her holiday story, and her denial of the graffiti. Samuel's frustration with these lies drives the narrative forward.
-
The Case as a Sphere: Samuel's metaphor of the case as a three-dimensional sphere with holes represents the search for completeness and truth. It symbolizes the complexity of the investigation and the need to connect disparate pieces.
-
The Dog as Clue: The dog's ownership becomes a potential key to uncovering a hidden maternal figure. It symbolizes the domestic and emotional ties that may link Libby to Marie Caron.
-
Holes in the Narrative: The chapter emphasizes gaps in the story—the missing teenagers, the unexplained DT, the vanished Justin Redding. These holes motivate Samuel's investigation.
-
Ethical Consumption: Samuel's vegetarianism, tied to environmental and animal welfare concerns, offers a brief but telling glimpse into his values, contrasting with the moral decay of the case.
Why This Chapter Matters
This chapter is pivotal because it crystallizes Samuel's theories and sets the stage for the next phase of the investigation. The connection between DT and Phin Thomson, the identification of Justin Redding as a key suspect, and the speculation about Marie Caron as a hidden mother all narrow the focus. Samuel's plan to interrogate Libby at the station and his intention to track down Justin and the dog's owner promise significant developments. The chapter also deepens our understanding of Samuel as a character, making the investigation feel personal and urgent.
Study Questions and Answers
1. Why does Samuel believe Libby's explanations are lies, and what evidence supports his suspicion?
Samuel finds Libby's story implausible on multiple counts: she claims to have given two-thirds of her inheritance to friends who are on holiday without phones and who didn't invite her to join them. He also notes the coincidence of the “I AM PHIN” graffiti matching her friend's name, and he questions why she is staying at Dido's house instead of her own flat. Her physical tells—high color in her cheeks—and her evasive answers reinforce his belief.
2. What is Samuel's theory about the initials DT and Phin Thomson?
Samuel connects the mysterious man with initials DT, who died alongside the Lambs, to Phin Thomson. He theorizes that DT was Phin's father, which would explain Phin's presence in the house and his later receipt of £2.48 million from the house sale. This theory fills a hole in the narrative by linking the unknown man to a known beneficiary.
3. How does the dog become a clue in Samuel's investigation?
Samuel recalls Libby's physical tells when she explained the dog's ownership, and he finds it implausible that she would share a dog with her adoptive mother in Spain. He speculates that if the dog doesn't belong to that mother, then Libby has another maternal figure—possibly Marie Caron, who received a third of the inheritance. This leads him to consider whether Marie Caron is one of the vanished teenagers, making the dog a potential link to the past.
