The semiotics of her uniform, a Tokyo cop. His ugliness was the stuff of legend. In the dreary chrome of the elevator shaft. They were dropping, losing altitude in a canyon of rainbow foil and sheet steel. The matrix had its own logic. Molly’s Zeiss Ikon rested on her lap as she watched the cityscape flow past.
