The Black Castle

The Black Castle is a fast-moving tale of battle between brothers. One is seen as evil because he is a vampire, while the other is perceived as good because he is a man of God. But the vampire only does what he has to do to survive while the churchman, an Inquisitor, inflicts pain for the power it confers upon him. Which is the greater evil? And who will win the soul (and body) of a pretty witch?
