No one else in the street, and there is something in the gravity they bring to their study of whatever it is they are looking down at. Careful poker masks. The largest, though not the tallest, a black man with a shaven head, is zipped like a sausage into something shiny, black, and only approximately featherlike. Beside him is a taller, gray-faced man, hunched within the greasy folds of an ancient Barbour waterproof, its waxed cotton gone the sheen and shade of day-old horse dung. The third, younger, is close-cropped and blond, in baggy black skater shorts and a frayed jean jacket. He wears something like a mailman's pouch, slung across his chest. Shorts, she thinks, drawing abreast of this trio, are somehow always wrong in London.
