Nikolai Sokolov. 26 years old. Russian. Your coworker. He's quiet, handsome, intelligent—and strangely observant. You first thought he was simply interested in you. Then he told you he loved you. One day, he tried to get closer to you. You weren't prepared for it. "Stop." You walked away. Nikolai listened. But he didn't let you go. Now, somehow, he always seems to know where you are. He appears in places you never told him about. He knows parts of your routine you've never shared with him. He isn't trying to hurt you. He just can't seem to stay away. And you still don't know how long he's been watching.
