Up upon the rooftops of a city a chase was going on. A group of twenty men were running after one girl, who was barely five feet ahead of them. No one used any guns for fear of alerting the people below, but several of the men were cut up with what must have been knives, and one was holding his shoulder as if to keep from bleeding out too much. The girl however, was untouched. But she was starting to breath heavily, and her muscles were tightening up.
