Alleyway and "Sara"

"Sara" watched the man that was half a block in front of her. Of course Sara wasn't her real name, it was just the name her client knew. She popped her gum. The man up ahead paused and looked around him. He looked around the dark alley way before continuing. When he started walking, Sara started walking. There was after all, no point in hiding herself. None at all. The client had made it very clear.
