Summary
The chapter opens in June 2019 with Detective Inspector Samuel Owusu and Detective Sergeant Donal Muir driving slowly along the Embankment in London. They have the blue light on, not because of an emergency, but to signal to other drivers why they are travelling at such a slow pace. Samuel holds his phone up, comparing the street ahead to a photograph from a music video.
They pull into Cheyne Walk, where Samuel identifies the house from the video. The property looks nothing like its former self: it is overgrown with creeping plants, the garden is full of rubble, and the windows are grimy and dirt-covered. A man answers the door—Oliver Wolfensberger—accompanied by a large but calm dog. Samuel introduces himself and explains they are investigating a historical murder and believe the property may be connected. Oliver, who has an accent Samuel assumes to be South African, invites them in without hesitation.
Inside, the house is stripped bare and has been virtually derelict for over twenty years. Oliver explains that he and his wife Kate only received the keys a couple of weeks ago and are about to begin a major renovation. Samuel shows Oliver the music video featuring Bridget Dunlop-Evers (known as Birdie) playing the violin. Oliver is excited to recognise the house, though he does not remember the song itself; he notes that his wife, who works in the music industry, would be thrilled to see it.
Oliver then shares what he knows of the house's history. It was left to a young woman named Libby Jones, who inherited it through a trust on her twenty-fifth birthday. Libby's parents had died in the house when she was a baby—Oliver believes it was a suicide pact—and she was found upstairs alone. Libby was adopted and only learned of the house when she came of age. Oliver mentions that the house was on the market for a long time due to its condition and its associations. He also recalls that a long investigative article about the story appeared in the Guardian a few years ago, though he deliberately did not read it. He provides the name of the solicitors who handled the trust.
Samuel asks to look around the house, and Oliver grants him free rein. Samuel and Donal explore the property, noting its poetic symmetry—four bedrooms and four bathrooms on the second floor. Samuel photographs the trees outside for the arboreal forensics expert. On the top floor, Donal spots something scratched into a skirting board: the words “I AM PHIN.” Samuel photographs it.
They climb a ladder to a small roof terrace. Samuel sifts through dead leaves in channels between the pitched roofs and finds mulch underneath. Near a chimney pot, the mulch appears to have been displaced and moved about. He photographs everything.
As they leave, Oliver offers full cooperation and provides the solicitors' details. Back in the car, Samuel tells Donal he is ninety percent certain this is the house where Bridget Dunlop-Evers met her end. Donal agrees it had “that vibe.” Samuel asks Donal to research the Guardian article while he visits the solicitors in Pimlico, and he plans to send the photographs to the tree expert by the end of the day.

Character Development
Samuel Owusu continues to demonstrate his methodical, detail-oriented approach to investigation. He notices the blue light's purpose, compares the street to the video still, photographs trees for forensic analysis, and carefully sifts through mulch with the toe of his shoe. His instinct—the ninety percent certainty—shows a detective who trusts both evidence and intuition. His decision to split tasks with Donal (researching the article versus visiting solicitors) reflects efficient investigative management.
Donal Muir remains the supportive, slightly less formal partner. His observation of the “I AM PHIN” scratching shows he is observant, and his agreement that the house “had that vibe” suggests he shares Samuel's instincts.
Oliver Wolfensberger is presented as open and positive-minded. He lets strangers into his home, expresses excitement about the music video, and explicitly states he wants to “overwrite” the house's bad history. His decision not to read the Guardian article reveals a deliberate avoidance of the property's darker past, even as he buys it.
Themes, Symbols, or Motifs
The derelict house as a repository of secrets. The Cheyne Walk house has been empty for over twenty years, preserving physical evidence—the scratched message, the displaced mulch—that might otherwise have been lost. Its decay mirrors the buried history of the family and the crime.
Family tragedy and inheritance. Libby Jones's story—orphaned as a baby, adopted, inheriting a house tied to her parents' deaths—connects the historical case to the novel's broader themes of family secrets and the weight of inheritance.
Forensic detail. Samuel's attention to trees, mulch, and scratched wood underscores the novel's interest in how physical evidence can unlock old cases. The “I AM PHIN” message is a particularly potent clue, linking the house to a name that may resonate with other characters in the narrative.
The past intruding on the present. Oliver's plan to renovate and “overwrite” the house's history is interrupted by the investigation, suggesting that the past cannot be easily erased.
Why This Chapter Matters
This chapter is pivotal because it confirms the Cheyne Walk house as the likely scene of Bridget's death and introduces two crucial pieces of evidence: the “I AM PHIN” scratching and the displaced mulch on the roof terrace. The former may connect to a character known as Phin (likely Phineas), while the latter suggests recent activity at the house. The chapter also ties together multiple threads of the novel—the historical case, Libby Jones's inheritance, and the Guardian article—setting up the next phase of the investigation. Samuel's ninety percent certainty gives the narrative momentum, and his division of tasks (Donal researching the article, Samuel visiting the solicitors) promises revelations about both the past and the present.
Study Questions and Answers
1. What physical evidence does Samuel find at the Cheyne Walk house, and why is each piece significant?
Samuel photographs the trees around the property for the arboreal forensics expert, which could help establish timelines or link plant material to other locations. He discovers the scratched message “I AM PHIN” on a skirting board, which may identify someone connected to the house. On the roof terrace, he finds displaced mulch near a chimney pot, suggesting that something was recently buried or moved there. Together, these pieces of evidence point to the house as a crime scene and hint at possible burial or concealment.
2. How does Oliver Wolfensberger's attitude toward the house contrast with its history?
Oliver is deliberately positive-minded. He bought the house knowing its tragic history—the parents' deaths, the baby found alone—but chose not to read the Guardian article about it, saying he did not want it to “stain” his consciousness. He describes his plan to renovate and “overwrite” the bad history. This contrast between his forward-looking optimism and the house's dark past highlights the novel's theme of how people choose to engage with (or avoid) difficult histories.
3. What does Samuel's ninety percent certainty reveal about his investigative method?
Samuel's certainty is based on a combination of concrete evidence (the music video matching the house, Oliver's account of the history, the physical clues) and professional instinct. His willingness to state a percentage rather than absolute certainty shows a detective who is confident but not overconfident, and who understands that investigations require both evidence and intuition. His immediate next steps—sending photos to the tree expert, visiting solicitors, and having Donal research the article—demonstrate his systematic approach to converting certainty into proof.
