A woman sat in a hotel bar, watching the door. Her appearance was neat and tidy: white blouse, fair hair tucked behind her ears. She glanced at the screen of her phone, on which was displayed a messaging interface, and then looked back at the door again. It was late March, the bar was quiet, and outside the window to her right the sun was beginning to set over the Atlantic. It was four minutes past seven, and then five, six minutes past. Briefly and with no perceptible interest she examined her fingernails. At eight minutes past seven, a man entered through the door. He was slight and dark-haired, with a narrow face. He looked around, scanning the faces of the other patrons, and then took his phone out and checked the screen. The woman at the window noticed him but, beyond watching him, made no additional effort to catch his attention. They appeared to be about the same age, in their late twenties or early thirties. She let him stand there until he saw her and came over.
