Supernatural Task Force: The Wolf and the Ancient.

Dave is a member of the Supernatural Task Force of the local police department in Newsport, CA. He is after a vampire who is a killer. Draining the blood of several victims to the point of death, completely unnecessary for a vampire. It's dangerous to hunt a vampire, but Dave has an edge. He is a legendary supernatural, only he doen't know what he is actually dealing with. When he does, he might not be the match for what he encounters.
