Due to recent events, Cassandra's nights were even busier as Batgirl than usual, but she still had her usual patrol route to run.
This time it appeared that she was arriving a bit late for some of the action, because someone seemed to have gotten to some muggers before she could. Someone was leaving a trail that was enticing for her to follow. Someone who had a similar crimefighting patrol route.
The trail led her to a rooftop, where a solitary figure in a trenchcoat and hat sat on a perch overlooking the street. He had the body language of a predator looking for prey. She crept up behind him, defenses at the ready, wanting to see how close she could get to him before he knew she was there.
