A Woman
Tom returned to his booth only five minutes later. But a lot can happen in five minutes. He looked at the screen, expecting to see a deserted metro station with only two or three people minding their own business, but he saw something different. Tom scanned the screen and suddenly noticed a woman. She was standing in the middle of the station, looking around in a confused manner. Tom’s training had taught him to recognize potential security risks, and this seemed like one of them. He knew he had to act quickly and decisively.
