Horowitz and Hawthorne observe a police interview with Akira Anno at the Notting Hill Gate police station. DI Grunshaw and her assistant, Darren, conduct the interview, covering Anno’s background, career, and her marriages to Marcus Brandt and Adrian Lockwood.
Anno admits she poured wine over Richard in a restaurant but claims her threat to hit him with the bottle was a joke. She calls Richard a liar who intimidated her during her divorce from Adrian. For the night of the murder, she says she stayed alone at her cottage near Lyndhurst before traveling to Oxford. Under pressure, she names her dinner companion as her publisher, Dawn Adams. After the interview, Akira recognizes Horowitz, and she becomes enraged that he is writing a book about the case. She threatens to assault him and to bring legal action.
That afternoon, Horowitz and Hawthorne visit Adrian at his house in Edwardes Square, London. Adrian claims his business was struggling during his divorce, which is why the settlement to Akira was small. He suggests Akira had sources of income that she kept hidden during proceedings. He confirms he gave Richard the bottle of wine that became the murder weapon. It was a thank-you gift for Richard’s legal representation of Adrian.
Adrian provides an alibi, stating he was with Davina in Highgate until just after eight o’clock on the night of the murder. He explains that he was introduced to Davina by Richard. He tells them that Davina’s late husband, Charles, was a university friend of Richard but died in a caving accident in which Richard was also present, some years ago in 2007. Adrian reports that a man with distinctive blue glasses broke into his office a few days before the murder. Horowitz notices homeopathic medicines on Adrian’s kitchen counter.
That evening, DI Grunshaw and Darren confront Horowitz at his flat. Grunshaw demands he act as her informant on Hawthorne’s investigation. Shaken, Horowitz conceals the visit when he and Hawthorne meet to speak with Davina.
Davina confirms Adrian’s alibi, saying he left her house at eight o’clock. Her son, Colin, says Richard recently told him he was being followed by a man with “something wrong with his face” (188). Davina recounts the details of the caving accident that killed her husband, naming Gregory Taylor as the third man there with Richard and Charles. She confirms Richard left her £100,000 in his will but she does not know what the number 182 means. After leaving, Horowitz searches Gregory online and finds a news article identifying him as a man who died under a train at King’s Cross the day before Richard’s murder.
The next day, Horowitz and Hawthorne go to the British Transport Police at Euston to investigate Gregory’s death. Detective Constable (DC) James McCoy and Police Constable (PC) Ahmed Salim explain they classify it as a PUT—Person Under a Train—and are treating it as an unexplained accident. They outline Gregory’s movements: He traveled from his home in Ingleton, arrived at King’s Cross the day before Richard’s murder, bought a coffee and a fantasy novel, Prisoners of Blood, and then went to the platform.
Witnesses report that Gregory shouted a warning just before he fell into the path of a train. Grainy CCTV shows him disappear into the crowd moments before his death. The officers add that his widow, Susan, said he was in London to see a friend. Convinced the two deaths are connected, Hawthorne decides they must visit Susan in Ingleton.
Horowitz structures these chapters as a sequence of competing narratives, establishing the unreliability of testimony and expanding on The Search for “Truth” in a World of Secrets and Lies. The explicit titling of Chapters 6 and 7 as “Her Story” and “His Story” signals a deliberate choice to present Akira’s and Adrian’s accounts not as objective fact, but as constructed versions of reality. It also indicates their pairing as characters, not only as ex-partners, but as balancing characters who combine to inform the novel’s moral and social satire. Akira portrays herself as a wronged intellectual, justifying her public outburst as a philosophical act where she uses humor “only to subvert the status quo” (82). Adrian, in contrast, frames her as a “totally self-obsessed and boring” (91) gold-digger. Neither account is presented as definitive; instead, the authorial focus rests on what the construction of each narrative reveals about the character’s motivations. This technique places the reader, alongside the narrator, in the role of an adjudicator, forced to dissect performances of victimhood and innocence. These chapters are an exploration of how individuals weaponize storytelling to control their own image.
Through the characters’ varied reactions to the investigation, Horowitz intensifies the novel’s metafictional commentary and explores Exposing Narrative Construction by Subverting the Ideas of Reality and Fiction. The characters are acutely aware of the narrative being constructed around them and actively seek to influence or escape it. Akira’s fury is directed not at the murder accusation itself but at the prospect of becoming a character in Horowitz’s book, a loss of authorial control she finds intolerable. DI Grunshaw’s physical confrontation with the narrator is a direct attack on his authorial agency; she attempts to co-opt his narrative for her own professional gain, forcibly recasting him from observer to informant. These interactions highlight how individuals use established narrative frameworks—from high literature to police procedurals—to interpret chaotic events, assert control, or justify their actions. The novel becomes a self-aware examination of the ethics of true-crime storytelling and the porous boundary between the logic of fiction and the untidiness of reality.
The initial appearance of the Doomworld books underscores the novel’s motifs of hidden identities and pervasive deception. Gregory’s last act before his death is to purchase a copy of Prisoners of Blood, a book from a fantasy series characterized as containing “extreme levels of violence and pornography” (134). This seemingly incidental detail introduces the Doomworld motif, which functions as a key to a significant secret, embodying the hypocrisy of a character who maintains a public persona starkly at odds with a private reality. It also creates a misleading link between the victim of the train incident and a world of violent fiction, a red herring that temporarily distracts from the true nature of his desperation. The discovery of Gregory’s death at King’s Cross, occurring just a day before Richard’s murder, breaks into the murder mystery, adding a second suspicious death. The reader is here asked to decide whether this parallel death is a distraction or a connection, setting up its later revelation as the epicenter of the central crime, and key to the novel’s argument that The Corrosive Power of Long-Buried Guilt will be shown to have ruined many characters’ lives.
