In a panorama around me, the sky is melting: reds and oranges into inky blue and nighttime. I stare through the surely colour-distorting, anti-UV-tinted, floor-to-ceiling window-walls. Out past the skyscrapers and into the blurred green-grey horizon beyond. My fingers feel numb but my face is hot, and prickles. I log out of my workstation, pack up my handbag and head towards the lifts.
