Dexter is an American television drama series, which debuted on Showtime on October 1, 2006. The sixth season premiered on October 2, 2011. The series centers on Dexter Morgan (Michael C. Hall), a blood spatter pattern analyst for the Miami Metro Police Department who moonlights as a serial killer. Set in Miami, the show's first season was largely based on the novel Darkly Dreaming Dexter by Jeff Lindsay, the first of his Dexter series novels. Subsequent seasons have evolved independently of Lindsay's works. It was adapted for television by screenwriter James Manos, Jr., who wrote the first episode.



Who is Dexter Morgan?

Dexter Morgan is a fictional character in a series of novels by Jeff Lindsay, including Darkly Dreaming Dexter (2004), Dearly Devoted Dexter (2005), Dexter in the Dark (2007), Dexter by Design (2009), Dexter Is Delicious (2010) and Double Dexter (2011). In 2006, the first novel was adapted into the Showtime TV series Dexter and its companion web series Dexter: Early Cuts.



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 serial killer who preys on other murderers who have escaped the justice system. He follows an elaborate code of ethics and procedures taught to him in childhood by his adoptive father, Harry Morgan (which he refers to as "The Code" or "The Code of Harry"), which hinges on two principles: Dexter can only kill people after finding evidence that they are guilty of murder, and he must dispose of all evidence so he never gets caught.
