Memory: The photograph in the pocket unpeeled into a small film when sunlight hit it. It showed two people on a bridge—one with the coat on, one without—both turning toward the camera with expressions that meant: we will not let this city close without taking something with us. Mara recognized the bridge. She followed the trail of the picture through alleys of old cinemas and found a projectionist who, for a favor, fed her a reel of citywide footage from fifty nights before the Fall. The footage was raw: lines of people moving like currents; a mayor shouting about pipelines; fireworks that spelled numbers in languages no one used anymore. Watching made Mara tremble because the footage remembered what the city had left out of its memorial plaques.
