Outside, an empty patrol car sat by the low curb. Like the small train that had brought her here, it was more a metal bathtub than a real machine. She looked left and right—no one around, just other cars passing by—so she walked over and climbed in. The car had one wide seat in the front with a single black joystick and brake pedal. The dash held a small terminal. She picked it up and saw the guard’s patrol number.
