When the Japanese or Korean man finished his exercise routine, he retrieved his belongings from the pigeonhole and exited the Fitness Center with Sokolov a few paces ahead of him. They ended up in the elevator lobby together. Sokolov, pretending to be distracted by a phone call, was slow to get on the elevator; the other courteously held the door for him. Sokolov scanned the button panel, reached to hit the button for 21, then hesitated, startled to find that his floor had already been selected. He hit the button again anyway. During the elevator ride, he pretended to lose his connection and, after uttering a couple of mild curses, began fiddling with the buttons, trying to make a new call. He was still doing so when the doors opened and the other man exited. Trailing well behind him, Sokolov ambled down the corridor. The man stopped before the door to Room 2139 and swiped his key card, only to get a red light. Sokolov kept on walking and disappeared around the next corner.
