William Green is Ruth Smith's fiancé. He loves Ruth with all his heart. He grew up with not much money. That's why he was so grateful that someone who grew up with plenty of money, like Ruth, chose to be with him. The only downside to him is that he's the murderer in Ruth's dreams. 

William doesn't have many lines, but it might be a little challenging when he is the murderer in Ruth's dreams. 

William has a medium pitched voice. It has some comfort to it except when he's in Ruth's dreams. That part of him sounds crazy and insane.
