A Witness Dismissed

Tansy’s Discredited Story
The official account
Eric Wardle explains that police rejected Tansy Bestigui’s claim that she heard a man arguing with Lula. Investigators believed the soundproofed windows made her account impossible and concluded she had invented details while using cocaine.
A false certainty
Strike notices that a witness can lie about circumstances and still report something real. Tansy’s changing explanations weaken her credibility, but do not establish that no argument occurred.
The Balcony Photograph

A View from Outside
The overlooked image
Strike tells Freddie Bestigui that a photographer captured a woman crouching on the balcony outside the Bestiguis’ flat. He has no photograph in hand, but his inference is based on the changing appearance of the building’s frontage.
A witness’s real location
The image gives a possible explanation for how Tansy could hear and see events that police thought she could not. Strike uses the claim to pressure Freddie into reconsidering his wife’s account and his own actions that night.
The Water on the Stairs

A Physical Trace
A remembered slip
While reenacting his search of Lula’s flat, Derrick Wilson recalls slipping on droplets of water on the stairs. He had not mentioned the detail before because it seemed insignificant at the time.
The roses matter
Strike links the drops to roses carried from the middle flat. The trace supports a route from the flat to Lula’s door and helps explain how an intruder could approach without being recognized as an ordinary visitor.
