Inspection of the Kentigern Gardens building

The inspection of the Kentigern Gardens building turns the investigation from a contest of accounts into a physical reconstruction. By examining the lobby, security systems, pool access, flat and stairway, Cormoran Strike and Robin Ellacott test what the building made possible—and what a witness might have overlooked. The crucial result is not a dramatic object discovered by searching, but a forgotten bodily memory: Derrick Wilson slipped on drops of water on the stairs. Strike later explains that John Bristow had carried white roses from a neighbouring flat, leaving those drops behind as he went to Lula Landry’s door.

The Building and Its Security

The inspection begins at the heavy, black-painted front door of number 18, Kentigern Gardens, which opens onto a marble lobby. A built-in mahogany desk faces the entrance; the staircase turns out of sight, while the lift and a solid wooden door sit against the opposite wall. Pink oriental lilies fill tall vases, and a mirrored wall reflects the people and fixtures, making the already polished lobby seem larger. The richly finished entrance gives the building the appearance of a private hotel, but Strike’s inquiry focuses on the practical details concealed within that display.

Derrick Wilson first shows Strike and Robin Ellacott the small room for off-duty guards. It contains a table and two chairs, a wall-mounted cabinet for the master keys, and a tiny toilet cubicle. Wilson, in a black uniform with brass buttons, then points out four black-and-white monitors hidden from visitors behind the security desk. They show the restricted street view from the front-door camera, the underground car park, the back garden, and the stationary lift. Two control panels operate communal alarms and the doors to the pool and car park; of the two telephones, one connects to an outside line and the other only to the three flats. The camera coverage is specific, not comprehensive: its four small screens show particular locations, while the later inspection also establishes that the pool itself has no camera.

The facilities behind the wooden door matter because they offer routes and spaces not immediately visible from the lobby. Wilson leads the investigators through the gym, a compact, mirrored room fitted with exercise machines and weights, and then down the marble stairs towards the pool. At the bottom, the chlorine smell gives way to warm, damp air. Wilson confirms that the pool door had not been locked on the night of Lula’s death. The pool is about fifteen metres long, with a covered surface, a mirrored wall, a tropical mural that reaches across the ceiling, a hexagonal jacuzzi and three changing cubicles with lockable doors. Strike’s question about cameras draws a clear answer: there are none there. The building’s security, therefore, has visible gaps as well as monitored points.

Reconstructing Wilson’s Search

Strike does not rely only on Wilson’s earlier description of what happened after he found Lula’s body. He asks Wilson to show, in order, how he searched the flat that night. Wilson recalls entering first, seeing open doors and not touching them. Strike guides him through the rooms with simple questions about what he felt, touched, saw and heard, shifting the interview from a rehearsed account towards a physical reenactment.

As the reconstruction proceeds, Wilson’s posture changes. He demonstrates how he held the doorjambs and leaned into rooms for a quick look. In the only bedroom, he moves at a slow-motion run, drops to his knees to show how he checked under the bed, and remembers that a dress had been crumpled beneath his legs. In the bathroom, he reproduces his turn to look behind the door before hurrying back towards the front entrance. The sequence gives Strike more than a list of rooms: it restores the order, gestures and pace of Wilson’s movements through the flat.

The investigators follow Wilson out and onto the stairs. Robin Ellacott, walking behind the two men, runs into Strike when Wilson suddenly stops; Strike raises a hand to quiet her, sensing that the security guard is absorbed in the memory. Wilson then remembers slipping backwards and landing hard on the stairs. There had been water there, he says, pointing to where the drops fell. He had never told the police: until the reenactment, he had forgotten the incident. Strike repeats the detail, and Wilson confirms that the water was on the stairs. What had seemed like an incidental fall becomes the missing observation that resolves a problem Strike has been carrying through the case.

The Clue in the Water

The importance of Wilson’s memory becomes clearer when set against the police account of the Bestiguis’ flat. Strike had already marked the cocaine left on the side of the bath and, more pointedly, the few seconds after Tansy Bestigui saw Lula fall past the window. Tansy’s accounts shifted, but she consistently maintained that Freddie Bestigui was asleep in bed when the fall occurred. She had shielded her face by pretending to push back her hair when Strike pressed her on the point. Without a plan of the flat, the exact positions of both Bestiguis at the moment Lula fell remained uncertain to him. The inspection does not erase those uncertainties; it supplies a separate, testable clue about the route taken after the death.

During the later confrontation with John Bristow, Strike provides the explanation. Bristow, he says, took several white roses from a vase in Flat Two, dried their ends, though not quite thoroughly enough, left the door ajar and carried them upstairs to his sister’s flat. The roses served as the means of approaching Lula at the door: she had been watching for her long-lost brother, and, seeing the flowers through the peephole, opened the door in excitement. The droplets Wilson found on the stairs were left by the flowers Bristow had carried. Strike’s reconstruction connects a detail initially absent from the witness’s police statement to the movement between flats and the fatal encounter.

What the Inspection Establishes

The inspection matters because it makes the building’s spaces and limitations part of the evidence. The monitors do not cover every interior area; the pool is unobserved by camera, and the staircase turns out of sight from the lobby. The unlocked pool door confirms an available passage into the leisure facilities, while the key cabinet and the guard’s working space establish the practical arrangements of building access. These details help Strike consider possible movement through the premises without mistaking the presence of cameras for complete surveillance.

More directly, the reenactment tests a witness’s recollection against the movements his body can still recover. Wilson had hurried through the flat, checked beneath the bed and behind the bathroom door, then returned to the stairs; his forgotten slip only re-emerges when he physically retraces the route. The sequence shows why Strike asks not merely what Wilson remembers, but what he did at each step. A small trace of water, disconnected from its source when first noticed, acquires meaning when joined to the layout, the route and Bristow’s later movements with the roses.

The scene also demonstrates the investigation’s fair-play logic: the eventual explanation depends on a concrete clue found in the account of the search, not on an unexplained device or a sudden new witness. Wilson’s forgotten observation is recovered in the reader’s presence during the same methodical inspection that gives it significance. The grand lobby and mirrored pool promise a world of wealth and controlled access; the decisive evidence is instead a few drops on a stair, left by flowers and preserved in a guard’s belated memory. Strike’s satisfaction when the connection becomes clear marks the inspection as a turning point: the building has yielded not a complete answer by itself, but the physical link that lets him reconstruct how Bristow reached Lula.
