I looked up then from my tray into the window of the restaurant. And there, as if it had just fallen from the sky or risen from the ground, was a dress: white and gauzy, fluttering at the straps and hems, like something by Alberta Ferretti. And there was a body in the dress, a long-limbed woman who turned and walked away just as I caught her eye. She seemed to be alone, and tall for someone local.
