Strike had never moved in the kinds of circles that dined at Cipriani. It was only as he walked up Davies Street, the sun warm on his back and imparting a ruddy glow to the red-brick building ahead, that he thought how odd it would be, yet not unlikely, if he ran into one of his half-siblings there. Restaurants like Cipriani were part of the regular lives of Strike’s father’s legitimate children. He had last heard from three of them while in Selly Oak Hospital, undergoing physiotherapy. Gabi and Danni had jointly sent flowers; Al had visited once, laughing too loudly and scared of looking at the lower end of the bed. Afterwards, Charlotte had imitated Al braying and wincing. She was a good mimic. Nobody ever expected a girl that beautiful to be funny, yet she was.

The interior of the restaurant had an art deco feeling, the bar and chairs of mellow polished wood, with pale yellow tablecloths on the circular tables and white-jacketed, bow-tied waiters and waitresses. Strike spotted his client immediately among the clattering, jabbering diners, sitting at a table set for four and talking, to Strike’s surprise, to two women instead of one, both with long, glossy brown hair. Bristow’s rabbity face was full of the desire to please, or perhaps placate.

The lawyer jumped up to greet Strike when he saw him, and introduced Tansy Bestigui, who held out a thin, cool hand, but did not smile, and her sister, Ursula May, who did not hold out a hand at all. While the preliminaries of ordering drinks and handing around menus were navigated, Bristow nervous and over-talkative throughout, the sisters subjected Strike to the kind of brazenly critical stares that only people of a certain class feel entitled to give.

They were both as pristine and polished as life-size dolls recently removed from their cellophane boxes; rich-girl thin, almost hipless in their tight jeans, with tanned faces that had a waxy sheen especially noticeable on their foreheads, their long, gleaming dark manes with centre partings, the ends trimmed with spirit-level exactitude.

When Strike finally chose to look up from his menu, Tansy said, without preamble:

‘Are you really’ (she pronounced it ‘rarely’) ‘Jonny Rokeby’s son?’

‘So the DNA test said,’ he replied.

She seemed uncertain whether he was being funny or rude. Her dark eyes were fractionally too close together, and the Botox and fillers could not smooth away the petulance in her expression.

‘Listen, I’ve just been telling John,’ she said curtly. ‘I’m not going public again, OK? I’m perfectly happy to tell you what I heard, because I’d love you to prove I was right, but you mustn’t tell anyone I’ve talked to you.’
