Professor Zimmer
- Professor Zimmer: When the devil attacks a man or woman with this foul disease of the vampire the unfortunate human being can do one of two things. Either he can seek God through the church and pray for absolution or he can persuade himself that his filthy perversion is some kind of new and wonderful experience to be shared by the favoured few. Then he tries to persuade others to join his new cult.
