Catwoman's tracking skills were indeed superb. Her maneuvers while tailing the car were completely natural, and halfway through, she even broke into another vehicle and switched cars. If Schiller had not had Gray Mist, he could easily have lost her.
Old Gun was cautious enough. He drove around the city in circles, but he still failed to shake Catwoman. Before long, he stopped at the back entrance of a building, then turned several corners on foot. Catwoman kept following behind him, while Schiller followed behind Catwoman.
Old Gun made his way into the underground parking garage of a building and took the elevator upstairs. Catwoman glanced at the elevator's location, then left the parking garage, circled to one side of the building, and counted the floors.
Soon, the lights came on in a window along the thirty-second-floor corridor. Catwoman circled around half the building again and took the freight elevator to the thirty-second floor, with Schiller close behind.
Old Gun passed through the corridor and arrived outside a laboratory. A heavyset Black woman emerged from the lab, and he took the capsules from her hand.
Catwoman stood around the corner in the corridor, watching the scene as she recorded their exchange with her phone camera.
What she did not know was that Schiller stood at one end of another corridor, witnessing everything as well.
And because he had Gray Mist, his hearing was far better than Catwoman's. After Old Gun left, he heard Rose walk into the laboratory while talking on the phone.
"Alright, I understand. I'll arrange for someone to pick them up at the airport tomorrow morning. We don't have time for a welcome banquet, so have them come straight to the laboratory. I want results within a week."
Schiller lay in wait outside the laboratory until morning.
