Carl Houseman Code 61, Book 4, (Paperback)

CODE 61: maintain radio silence. someone may be listening.

Investigating the apparent suicide of a colleague's niece, Iowa Deputy Sheriff Carl Houseman is startled to uncover a group that transforms the dark fantasies of vampire legend into grisly reality: they ritualistically drink small amounts of one another's blood. As Carl is drawn deeper into this unnerving world, it becomes clear that the dead woman may have been the victim of a twenty-first-century Dracula.

The prime suspect, Dan Peale, is a sinister presence within the group--a man some say drinks blood and never, ever dies. It's an outlandish, heinous theory, but then suspicions are bolstered by rumors of a card-carrying vampire hunter who is also pursuing Peale. All too soon, Houseman finds himself scrambling to track a vampire--before he kills again.
