His breath came in ragged pants as his shoes splashed through the puddles in the streetlamp lit alley. Just keep running, he thought. Just keep running. If he catches you you're dead. The vague shadow in the corner of his eye was still there- taunting him, playing with him like an orca with a seal, or a young psychopath w/ a poor, unfortunate animal- barely distinguishable from the other shadows of the night.
Another sound of metal on brick dopplered in his ear. Was that a knife? Is he throwing knives at me now? I have to find someplace to hide. Need time to think.
He started rounding corners every chance he got; using fire escapes, jumping fences, ducking in unlocked doors. He didn't know where he was. He didn't care, just so long as the one hunting him wasn't on his trail anymore. No place seemed to be good enough to hide from HIM, so he just kept running. He didn't know how long he ran, but he knew dawn was approaching when he finally collapsed in a heap against a chain link fence at the edge of a vacant lot beside the trainyards.
