Inside, they found Ravenheart, Lim, and two other troopers clustered around a small closed-circuit video monitor. The image showed another building similar to this one, with a crisscross of train tracks and uncoupled railroad cars in the background. From what he'd seen on approach Kyle suspected the area was almost directly across the street. He could see movement on the screen, some figures clustered around one of the doors, given away by the telltale glow of cigarettes. Beyond them, Kyle could just barely make out the front end of what seemed to be a Chicago Transit Authority bus.
