The Basis for a New Showtime Original Series Starring Michael C. Hall Meet Dexter Morgan a polite wolf in sheep’s clothing. He’s handsome and charming but something in his past has made him abide by a different set of rules. He’s a serial killer whose one golden rule makes him immensely likeable: he only kills bad people. And his job as a blood splatter expert for the Miami police department puts him in the perfect position to identify his victims. But when a series of brutal murders bearing a striking similarity to his own style start turning up Dexter is caught between being flattered and being frightened?of himself or some other fiend.
