The smell of trash assails you as you vault over a low dividing wall and right into a pile of refuse. You stand up in disgust but immediately trot down the dank alley before you; there isn't a second to lose in this desperate flight for your life. Your partner silently shadows you as you stalk to the next street. He may be an impulsive psychopath, but right now you have bigger problems. Your pursuers won't be long before they, too, are knee-deep in trash, but every escape holds a possible enemy. You scan the street, assess the possibilities and start to step out of the alley, prepared to casually blend in with the scurrying pedestrians. Just before your foot hits the pavement, your eyes lock onto the crisp uniform of the Shanghai police force bobbing through the crowd straight in your direction. You turn to vault back over the alley wall but hear the shouting voices of your pursuers on the other side. It seems that escape is impossible: how will you get out of this impossible situation?
