wyvernfriend
This time he's investigating a women's group, there have been some disappearances associated with it and this group seems to be getting their fingers in magic as well. He's authorised to use lethal force, and he does. As well as torture and all sorts of unpleasant things. But somehow he does all this calmly, in a very Dexter way, and the magic is a tool, something that he uses rather like the knife he's fond of.
There are some pretty intense scenes of torture and some sex involved so this one is definitely not for younger people, but he's a compelling character, no matter how unpleasant.
