Consider the sociopath. He is friendly. He is personable and likeable. He is very good at gaining your trust. And at any time he will stab you in the back or kill you for personal gain and he will feel no guilt. Now, imagine that the sociopath is a shape changer. In an instant he can be a snake, a bear, a bat. If he wants your car he has no problem with becoming a poisonous spider and biting you for it. If he is hungry he has no compunction against becoming an alligator and eating you. He also cannot be killed. This is a description of Brass. There is only one way to stop him and it involves heeding the ancient folklore of the Cherokees.
