Hunter - a short pay-what-you-want SciFi tale

Pyke chased the girl down a street still wet with the afternoon’s rainfall. A thin sliver of moon was glowing behind the thinning clouds, but it wasn’t bright enough to pierce the darkness between thefew street lamps that still worked. The girl was fast. He had to stay close, or she’d escape.
Pyke had let the girl put about 500 feet between them when she ranthrough a bright pool of light and was swallowed by darkness. When she didn’t reappear, Pyke knew he had her, for there was only one place she could have gone. He followed her through a once-ornate gateway into the old city, where the colony had been founded a century before.
Her footfalls echoed off rows of empty windows down narrow streets that seemed to turn back on themselves, an ancient trick intended to confuse invaders. When the Gan arrived, they solved this puzzle by simply bombarding most of the buildings and walls from low orbit until there weren’t many places left to hide. Hunters like Pyke—a second-generation Goa colonist who’d grown up in the old city—knew every twist, every turn, every blind alley and every hidden basement.
It wasn’t the first time Pyke had pushed a rebel into the avenues. In the six months he’d been working for the Gan, he’d let dozens of terrified patriots think they were making their escape into the old city’s maze-like streets, only to trap them in one of its countless dead ends, where he’d have a little fun before turning them over to his masters.
He heard a splash just down the block, followed by a yelp. She must have fallen in a puddle, Pyke thought. Shallow craters were everywhere in these streets; filled with water, they made quite effective traps. Pyke slowed to a jog and grinned. It was only a matter of time now
