The agents were only twenty feet away now. One of them leveled a finger at Zhao.
"Stop! Federal agents!"
Zhao saw the gap between the closing doors. It was starting to close.
He put his shoulder down and lunged like a sprinter hitting the finish line.
He tumbled into the train just as the thick rubber edges closed shut.
*THUD.*
One of the agents slammed into the glass window from the outside, his face twisted in anger. He banged on the door, but the gears were already locked.
The train began to move. Within seconds, it pulled away from the platform, disappearing into the dark tunnel.
Zhao sat on the floor of the moving train, breathing hard, watching the station lights fade into the dark.
Back at the precinct, Pamela looked at screen.
"Signal lost," she whispered, leaning back in her chair. "The satellite can't penetrate that deep. He's off the grid. Move to the next station."
The agents didn't waste a second.
