‘You’ll have to wait,’ he said curtly. ‘Bryony’s busy and Ciara’s going to be hours. You can park yourself in there if you want,’ he pointed towards the right-hand room, where the edge of a tray-laden table was visible, ‘or you can stand around and watch like these useless fuckers,’ he went on, suddenly raising his voice and glaring at the huddle of elegant young men and women who were staring towards the light source. They dispersed at once, without protest, some of them crossing the hall into the room opposite.

‘Better suit, by the way,’ Somé added, with a flash of his old archness. He marched back into the room from which he had come.

Strike followed the designer, and took up the space vacated by the roughly dispatched onlookers. The room was long and almost bare, but its ornate cornices, pale blank walls and curtainless windows gave it an atmosphere of mournful grandeur. A further group of people, including a long-haired male photographer bent over his camera, stood between Strike and the scene at the far end of the room, which was dazzlingly illuminated by a series of arc lights and light screens. Here was an artful arrangement of tattered old chairs, one on its side, and three models. They were a breed apart, with faces and bodies in rare proportions that fell precisely between the categories of strange and impressive. Fine-boned and recklessly slim, they had been chosen, Strike assumed, for the dramatic contrast in their colouring and features. Sitting like Christine Keeler on a back-to-front chair, long legs splayed in spray-on white leggings, but apparently naked from the waist up, was a black girl as dark-skinned as Somé himself, with an Afro and slanting, seductive eyes. Standing over her in a white vest decorated in chains, which just covered her pubis, was a Eurasian beauty with flat black hair cut into an asymmetric fringe. To one side, leaning alone and sideways on the back of another chair, was Ciara Porter; alabaster fair, with long baby-blonde hair, wearing a white semi-transparent jumpsuit through which her pale, pointed nipples were clearly visible.

The make-up artist, almost as tall and thin as the models, was bending over the black girl, pressing a pad into the sides of her nose. The three models waited silently in position, still as portraits, all three faces blank and empty, waiting to be called to attention. The other people in the room (the photographer appeared to have two assistants; Somé, now biting his fingernails on the sidelines, was accompanied by the cross-looking woman in glasses) all spoke in low mutters, as though frightened of disturbing some delicate equilibrium.
