Lucy Fly’s arrest and police questioning turn the disappearance of Lily Bridges into a test of how far suspicion, unstable memory, and a convincing story can be mistaken for proof. Taken from her Tokyo office after Lily’s remains have been reported recovered from Tokyo Bay, Lucy eventually describes a murder in vivid detail, then recognizes that she has fabricated the confession. Photographs received by police subsequently undermine the account, and she is released without charges.

Context and Arrest

On the morning of her arrest, an earthquake wakes Lucy several hours before the police arrive. She stresses that the tremor is ordinary in Tokyo and does not mean that it caused or foretold the arrest. Still, her reaction reveals the nervousness that has accumulated since Lily’s death and Teiji’s disappearance: Lucy puts on a cycling helmet, retrieves a flashlight, and checks that her whistle and earthquake-water bottle are nearby before crouching in a corner. She cannot return to sleep easily, and her usual word game, built around different meanings of the Japanese word for earthquake, does not distract her. Memories of sleeping beside Teiji briefly comfort her, but the morning proceeds into an arrest she has already begun to expect.

That afternoon, Lucy is at work translating technical instructions for a new bicycle pump. The routine task has helped occupy her mind amid the recent disasters. When she notices her colleagues looking toward the office entrance, two policemen are there. Lucy tries to get ahead of the humiliation of being arrested in front of an unsupportive audience, telling coworkers that the officers probably only want to ask more questions. They say they are taking her to the station in connection with Lily’s disappearance and ask her to bring her alien registration card. Their explanation that there have been new developments makes Lucy fear that the missing parts of Lily’s body have been found and that the police can formally identify her.

The office has already changed since a copy of the Daily Yomiuri circulated a report that a woman’s torso had been recovered from Tokyo Bay and was believed to belong to Lily. Lucy recalls her colleagues avoiding her after reading it; she cannot tell whether they suspect her of murder or simply do not know how to respond to Lily’s death. The police arrive against that background of public suspicion, although the case has not yet established what happened to Lily.

Questions, Witnesses, and Uncertain Memory

At the station, the questioning focuses on the night Lily disappeared. The investigator says Lucy was, as far as police know, the last person Lily spoke to. Lucy challenges the vagueness of the timeline, asking which night counts as the night of the disappearance, and recalls bringing in her washing when Lily called. She says she remembers nothing after that and supposes she returned to her laundry. A neighbor, however, saw her speaking with Lily outside her front door. Lucy answers that the witness presumably saw what she has just described; the investigator’s patient, expectant manner makes the exchange feel less like a settled account than a search for a confession.

The neighbor supplies another incriminating detail: Lucy appeared to be carrying a bundle. Lucy mocks the report and identifies the likely witness as the woman next door, who vacuums for hours and is her only immediate neighbor. She says she had been angry with Lily, but the reported bundle gives that anger an ominous possible interpretation. The evidence presented by police is circumstantial and dependent on another person’s observations; the questioning does not make the bundle’s identity or purpose certain.

As the interview continues, Lucy cracks her fingers one by one while Kameyama waits. Oguchi picks at the seam of his trouser knee, and Lucy reads his unease as an awareness of the crime she may have committed. Her own recollection of the night remains a blur that, she says, must be recovered bit by bit before she can tell Kameyama what happened. When he changes the subject, her thoughts range from trivial questions to her earlier responsibility for Noah Fly’s death and Mrs. Yamamoto’s death. The sequence links the current interrogation to Lucy’s broader inability to separate what she remembers, what she fears, and what she believes herself capable of doing.

A Confession Made Under Interrogation

After Lucy begins talking, she tells police the story she thinks they want to hear. It has a clear emotional logic: jealousy of Lily, rage at being let down, and an obsessive love for Teiji that prevents Lucy from accepting that the relationship is over. She describes using a pair of stockings as a weapon, catching Lily off guard because Lily still trusts her enough to smile, and dragging Lily’s warm, lifeless body to a hiding place. The account’s fluency and sequence give it the shape of a complete solution to the case, but its apparent completeness is not independent evidence that it is true.

Lucy subsequently states that she did not kill Lily and that the confession was a story she spun. At the same time, she does not claim uncomplicated innocence. She is exhausted and says she no longer trusts herself, recalling how people have slipped through her grasp. She also considers the ways her own choices may have helped bring Lily into danger: she introduced Lily to Teiji, persuaded her not to return to Britain when she wanted to, and wonders whether Lily would have come to her street that night if Lucy had answered the phone. Her formulation, “Not guilty, but not not guilty,” distinguishes legal responsibility for murder from the guilt and regret she attaches to her part in the relationships surrounding Lily.

Lily’s earlier disclosures provide context for her presence in Japan, but do not establish a motive for her murder. She told Lucy that she had left Andy, her possessive former boyfriend, after their engagement collapsed and she wanted to start over. She described his suspicion of men who spoke to or looked at her, and recounted finding a cheap listening device he had hidden in the lining of her handbag. Lily said she had delayed leaving because she expected him to follow her and feared the fights that would result. This history makes her effort to create distance intelligible; it does not verify Lucy’s invented account of the killing.

New Evidence and Release

Lucy’s confession does not lead to charges. Mrs. Katoh hopes Lucy will come and stay at her home in Tokyo, while Lucy agrees partly because she still expects to be convicted. Instead, after a day has passed, Lucy learns she will be released. The case against her is circumstantial, and investigators have found no fingerprint or DNA sample from her on Lily’s body.

A new envelope delivered to police after Lucy’s details appear in national newspapers contains two photographs. The account describes the first: it shows Lily at a McDonald’s near Lucy’s home on the night of the murder, two hours after Lily was seen at Lucy’s front door. A cashier recognizes Lily and recalls that she and a Japanese male friend seemed distressed and had difficulty communicating. Lily leaves her cheeseburger untouched but drinks her Coke. The photograph places her with someone else after her encounter with Lucy, contradicting the confession’s account of Lucy killing her following that visit.

The evidence also separates Lucy’s brief outing from Lily’s death. Police determine that Lucy was outside for only about ten minutes with her stockings over one shoulder, and the neighbor had not reported hearing her go out again that night. The details that had seemed to support a murder narrative—the neighbor’s sighting, the bundle, and Lucy’s own confession—therefore fail to prove that she killed Lily. The photographs do not resolve every circumstance of Lily’s death, but they help explain why the police release Lucy without charges.

Narrative Significance

The arrest sequence sets observation against inference at every stage. A neighbor sees Lucy speaking to Lily and apparently carrying a bundle; police treat these details as reasons to question her, while Lucy offers explanations that cannot initially be checked. She then supplies a far more dramatic account herself, but the confession proves less reliable than the small, external trace of Lily’s presence at the restaurant. The case turns not on how persuasive a story sounds, but on whether it holds against independently obtained evidence.

Lucy’s narration makes that distinction deliberately unstable. She insists that the morning earthquake is merely part of the day’s sequence, yet the tremor’s uncertain warning sound echoes the book’s larger uncertainty about what can be known in advance or reconstructed afterward. In the station, she moves between gaps in memory, fear of her own capacity for harm, and a confession composed to fit what she thinks the investigators want. Her release settles the immediate legal outcome but leaves her moral accounting unresolved: she is not convicted of Lily’s murder, yet she continues to regard her choices and silences as part of the story that led to Lily’s death.
