After more than three hours of walking, I look at my watch and realize the tube station closed a long time ago. It’s 1:30 a.m. We return to that UFO of a church. Sandhu hails a black cab, and I plop into the backseat and ask the driver to take me home by the river. I stare out the window and watch the empty sidewalks and streetlamps whirl past. The cab driver asks what I do in my spare time. He shares that he owns a telescope and enjoys looking at the stars and the moon on his off nights. “But there’s just too much light,” he says. “It’s hardly dark at all. You can’t see what you used to.” I know, I say, I know.
