In both the novels and the TV series, Dexter is a forensic blood spatter analyst who works for the fictitious Miami-Metro Police Department; in his spare time, he is a vigilante who channels his urge to kill onto other murderers who have escaped the justice system. He follows a code of ethics taught to him in childhood by his adoptive father, Harry Morgan, which hinges on two principles: Dexter can only kill people after finding conclusive evidence that they are guilty of murder, and he must dispose of all evidence so he doesn't get caught.
