Metropolitan Police

The Metropolitan Police is the force responsible for investigating Lula Landry’s death in London. Its first conclusion—that she had died by suicide—shapes the official account and the early handling of evidence; the later investigation, informed by Cormoran Strike’s independent reconstruction, reveals how assumptions and overlooked details left the circumstances open to question. The force also becomes the authority that eventually arrests John Bristow, whose guilt Strike establishes through a chain of specific, recoverable clues.

Initial Investigation and Its Assumption

The detective in charge was convinced from the outset that Lula’s death was suicide, with her use of lithium offered as the reason. John Bristow tells Strike that the inquiry overlooked matters that had subsequently attracted attention online. That early framing matters because it risks making Lula’s known medication a conclusion in itself: a fact about her health becomes the lens through which the death is read, rather than one element to weigh against the circumstances and evidence.

The case file Strike later examines shows that the official account did not settle every question. In particular, Tansy Bestigui’s changing statements about what she saw and where her husband was at the moment Lula fell left the couple’s precise positions unproven in Strike’s assessment. He also noted the cocaine found in the Bestiguis’ bathroom and Tansy’s insistence that Freddie had been asleep. The Metropolitan Police’s initial view and the unresolved inconsistencies in the statements coexist in the file; the latter do not, by themselves, establish what happened, but they show why the first conclusion could not answer every investigative question.

Scene Response and Evidence

Security guard Derrick Wilson recounts that, after being told of the fall, he took the master key from the back room and went upstairs to Lula’s flat. The police later searched the apartment, and Wilson’s account of the search became a point of close scrutiny when Strike asked him to retrace its order. During that reconstruction, Wilson recalled slipping on water on the stairs—an incident he had forgotten. The detail acquired significance because Strike later connected the drops to water carried out with roses from another flat, making an apparently minor trace part of his account of how the murderer reached Lula’s door.

Wilson describes a scene that quickly drew in a larger public. Plainclothes officers requested keys to the basement gym, pool, and car park; officers were also sent to speak to Tansy and summon backup as neighbors gathered, called others, or took photographs. The street was heavily snowed upon, and when forensic staff arrived, a tent was erected over Lula’s body. The press arrived at about the same time, while police vehicles and cordons closed off part of the street. The account conveys both the practical demands of securing a scene and the media attention that surrounded a death already familiar to the public.

Access, Records, and Reconstruction

The building’s security arrangements became central to reconsidering how someone could have entered and moved through it. Strike observed the keypad at the front door and a camera above it, neither of which Bristow had mentioned. Wilson confirmed that the external code had been changed after Lula’s death because so many Metropolitan Police officers had learned it during the inquiry; it had not changed during the three months Lula lived there. The code was 1966. The building’s monitoring system included views of the entrance, underground car park, back garden, and lift, alongside controls for communal alarms and access to the pool and car park. These systems made the building appear closely watched, but the code’s prolonged use and the temporary absence of the security guard created questions about who could pass through and when.

Strike focused on the quarter-hour after Lula entered the building, when photographers had left and Wilson had abandoned the desk because he was ill. The access problem was not simply whether the front door was locked: a person outside would also have needed to know that the lobby had become temporarily unguarded and to enter using the keypad. Robin Ellacott pointed out the need for the code; Strike considered that it might have become widely known if security staff did not change it regularly. The investigation thus turns a seemingly protected address into an opportunity structure whose safeguards depended on routine, restricted information, and an attendant’s presence.

Strike’s reconstruction ultimately gave the Metropolitan Police a specific reason to search the safe in Bristow’s mother’s home. He explained that Bristow had carried white roses from another flat to Lula’s door, leaving small drops of water on the stairs; Wilson later slipped on them. The flowers also served as a visual lure through the peephole, prompting Lula to open the door. When Bristow insisted there was no proof, Strike answered that the police should already have obtained a warrant to search the safe. This exchange marks the point at which the independent detective’s reconstruction becomes actionable police work rather than a competing theory alone.

Arrest and Continuing Investigation

Ten days after Bristow’s arrest, the Metropolitan Police urgently required Lieutenant Jonah Agyeman to return to Britain from his second tour in Afghanistan. The circumstances of his sister’s death had attracted international attention, and the Army sought to shield him from the press while he was in Britain. The police investigation therefore extended beyond the immediate suspects and scene: it involved locating and speaking with Lula’s half-brother, whose identity and family connection had become relevant to the case.

Strike later tells Jonah that the police had found Rochelle Onifade’s mobile phone in Bristow’s mother’s safe. Bristow had reset the safe’s code so that only he could access it; the number was 030483, the date of Charlie Bristow’s death. The phone’s recovery supplied a concrete piece of evidence against Bristow and connected the safe to the investigation into Rochelle’s murder as well as Lula’s death. The Metropolitan Police’s role in the novel therefore develops from an inquiry constrained by an early conclusion into the force that pursues new evidence, seeks a warrant, arrests Bristow, and recovers an object central to the wider sequence of crimes.
