‘And her ex will go absolutely ballistic if she starts dragging the press back into their lives,’ Ursula said, her dark eyes boring into Strike’s. ‘They’re trying to thrash out a settlement. It could seriously prejudice her alimony if that all kicks off again. So you’d better be discreet.’

With a bland smile, Strike turned to Tansy:

‘You had a connection with Lula Landry, then, Mrs Bestigui? Your brother-in-law works with John?’

‘It never came up,’ she said, looking bored.

The waiter returned to take their orders. When he had left, Strike took out his notebook and pen.

‘What are you doing with those?’ demanded Tansy, in a sudden panic. ‘I don’t want anything written down! John?’ she appealed to Bristow, who turned to Strike with a flustered and apologetic expression.

‘D’you think you could just listen, Cormoran, and, ah, skip the note-taking?’

‘No problem,’ said Strike easily, removing his mobile phone from his pocket and replacing the notebook and pen. ‘Mrs Bestigui—’

‘You can call me Tansy,’ she said, as though this concession made up for her objections to the notebook.

‘Thanks very much,’ said Strike, with the merest trace of irony. ‘How well did you know Lula?’

‘Oh, hardly at all. She was only there for three months. It was just “Hi” and “Nice day”. She wasn’t interested in us, we weren’t nearly hip enough for her. It was a bore, to be honest, having her there. Paps outside the front door all the time. I had to put on make-up even to go to the gym.’

‘Isn’t there a gym in the building?’ asked Strike.

‘I do Pilates with Lindsey Parr,’ said Tansy, irritably. ‘You sound like Freddie; he was always complaining that I didn’t use the facilities at the flat.’

‘And how well did Freddie know Lula?’

‘Hardly at all, but that wasn’t for lack of trying. He had some idea about luring her into acting; he kept trying to invite her downstairs. She never came, though. And he followed her to Dickie Carbury’s house, the weekend before she died, while I was away with Ursula.’

‘I didn’t know that,’ said Bristow, looking startled.

Strike noticed Ursula’s quick smirk at her sister. He had the impression that she had been looking for an exchange of complicit glances, but Tansy did not oblige.

‘I didn’t know until later,’ Tansy told Bristow. ‘Yah, Freddie cadged an invitation from Dickie; there was a whole group of them there: Lula, Evan Duffield, Ciara Porter, all that tabloidy, druggie, trendy gang. Freddie must have stuck out like a sore thumb. I know he’s not much older than Dickie, but he looks ancient,’ she added spitefully.

‘What did your husband tell you about the weekend?’

‘Nothing. I only found out he’d been there weeks later, because Dickie let it slip. I’m sure Freddie went to try and make up to Lula, though.’
