Mr. Alexander looked up at the office building. Surely that was new? He glanced at Ms. Sharp, walking beside him. Ms. Sharp was unperturbed. Should he ask her about the large gray metal box, with the three turrets and smokestack? He was certain that it hadn’t been there earlier this week. It looked like the kind of addition that required contractors with tool belts and large machinery. It must have always been there, because he would have noticed a crane.
Ms. Sharp flicked her eyes sideways at her companion. Why hadn’t she ever noticed that addition? But she was afraid that inquiring would make her seem foolish and unobservant, so she didn’t.
The time-travellers had seen this before, around the globe and throughout history. Just like tying a firecracker to a cat’s tail, but the cat never noticed. Eventually someone would ask, but by then it was always too late.
