Summary
The chapter opens with Samuel waiting on two crucial pieces of evidence. The warrant to examine Libby Jones's bank records takes a full twenty-four hours to obtain, but in the meantime the arborist's report arrives. It confirms that the trees overhanging number sixteen Cheyne Walk—London planes, trees of heaven, and Persian silk—are the exact species that formed the mulch found attached to Birdie Dunlop-Evers's remains. This provides the proof Samuel needs that Birdie's body was kept on the roof of the house.
Samuel and Donal return to Cheyne Walk to join the forensic team, including investigator Saffron Brown. At the bottom of the garden, past a tree with a circular bench, they find small white bones in a flower bed. Saffron quickly reassures them they are cat bones, not human. She then points out the rectangle of soil where the herb garden once stood and identifies the large terra-cotta pots where Atropa belladonna was grown—the poison used by the house's owners and the mystery man in the 1994 deaths.
Back at the station, Samuel and Donal re-examine the original police reports. The first responders were PCs Robbin and Shah, followed by a crime scene team and a family liaison officer named Felicity Measures, who dealt with the baby found at the scene. The two older Lamb children, Henry and Lucy, were never traced. The reports describe the house as having a somewhat cultlike history. The suicide note was initialed by the dead: ML, HL, and DT. A missing person search for someone with the initials DT matching the mystery corpse was conducted but abandoned three years later without success.
Samuel recalls Miller Roe's 2015 Guardian article, which also hit a dead end on DT. The article's final line mentioned a possible lead: a family man who arrived from France in 1988 at age forty-two with his wife and two children, never heard from again. A missing person report was only filed in 2006 when his mother was near death, but the police could not trace him. Samuel tries to contact Miller Roe but finds his flat in South Norwood locked and empty; an upstairs neighbor says Roe mostly lives with his girlfriend.
The financial report finally arrives. Libby Jones received £7.45 million into her current account and on the same day transferred £2.48 million each to two accounts: one belonging to Miss Marie Valerie Caron and the other to Mr. Phineas Thomson. The name Phineas triggers a memory—Samuel flips through his notebook and finds 'I AM PHIN,' the words Donal discovered scrawled on a skirting board at Cheyne Walk. The graffiti that once meant nothing now means everything.
Samuel instructs his colleague Maura to investigate both recipients thoroughly, including their social media presence. Then he and Donal drive to St. Albans. Libby is not at her flat, so they go to Northbone Kitchens, the showroom where Dido works. Dido is guarded and unhelpful, claiming she has no idea where Libby is and denying ever hearing the name Phineas Thomson. Samuel notices her lying tics—her gaze drifting to the ceiling, a shoulder rolling forward, her teeth clenching before she speaks. He takes a business card from the showroom counter and, after leaving, tells Donal they are going to Dido's house, using the address printed on the card.

Character Development
Samuel's investigative confidence grows noticeably in this chapter. He experiences a warm feeling of euphoria when the arborist's report arrives, and later, alone at his desk, he cannot contain his excitement over the financial report—shouting, punching the air, and spinning in a circle. His instinct to check Dido's business card for her address shows a sharper, more proactive side to his detective work.
Dido emerges as a more significant figure. Her guarded demeanor and obvious lying tics—the ceiling gaze, the shoulder roll, the clenched jaw—reveal that she knows more than she is admitting. Samuel suspects she is protecting Libby, and her denial about Phineas Thomson is clearly false.
Saffron Brown provides a brief but memorable presence, guiding Samuel and Donal through the forensic discoveries with evident relish for the gothic narrative unfolding at Cheyne Walk.
Themes, Symbols, or Motifs
Forensic evidence as narrative: The chapter shows how physical evidence—tree species, cat bones, terra-cotta pots—builds a story that police reports and journalism could not. The arborist's report is the first hard proof linking Birdie's remains to the house.
Hidden identity: The initials on the suicide note (ML, HL, DT) and the untraced DT figure underscore the theme of people who vanish without a trace. The financial trail reveals two new names—Marie Valerie Caron and Phineas Thomson—who may be Libby's long-lost siblings.
The 'I AM PHIN' motif: The graffiti that seemed meaningless now becomes a key clue, connecting the Cheyne Walk house to Phineas Thomson. The motif suggests identity asserted in a hidden place.
Deception: Dido's lies, Miller Roe's absence, and the abandoned missing person search all reinforce the theme of concealment. The chapter repeatedly shows people who know more than they reveal.
Why This Chapter Matters
This is a pivotal chapter in the investigation. The arborist's report provides the first conclusive link between Birdie Dunlop-Evers's remains and the Cheyne Walk property, while the financial report reveals that Libby has been distributing her inheritance to two individuals—one of whom, Phineas Thomson, is directly connected to the 'I AM PHIN' graffiti. The chapter also deepens the DT mystery by introducing a possible identity for the third corpse, and it positions Dido as a potential obstacle or ally in locating Libby. Samuel's decision to go to Dido's house sets up the next stage of the investigation.
Study Questions and Answers
1. What does the arborist's report prove, and why is it significant?
The arborist's report confirms that the trees overhanging number sixteen Cheyne Walk—London planes, trees of heaven, and Persian silk—are the same species that formed the mulch found attached to Birdie Dunlop-Evers's remains. This proves her body was kept on the roof of the house, establishing a direct physical link between the property and the remains.
2. Why does the name Phineas Thomson matter to Samuel?
Samuel connects the name Phineas to the 'I AM PHIN' graffiti that Donal found scrawled on a skirting board at Cheyne Walk. The graffiti, which previously seemed meaningless, now appears to be an assertion of identity by someone connected to the house and to Libby's financial transfers.
3. How does Samuel know Dido is lying about Phineas Thomson?
Samuel observes Dido's physical tics when she denies knowing Phineas: her gaze detaches and reaches for the ceiling, one shoulder rolls forward, and she clenches her teeth before speaking. These cues convince Samuel she is about to lie, and her denial is therefore unreliable.
