Dexter /

Dexter is an American television drama series that centers on Dexter Morgan (Michael C. Hall), a bloodstain pattern analyst for the Miami Metro Police Department who moonlights as a serial killer. The show debuted on October , 2006, on Showtime and the fifth season ended on December 12, 2010. As of December 2, 2010, the show has been renewed for a sixth season. Set in Miami, the show's first season was largely based on the novel Darkly Dreaming Dexter by Jeff Lindsay, the first of his series of Dexter 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. Dexter structures his killing around "Harry's code", a body of ethics and procedures devised by his adoptive father Harry Morgan (who was a Miami cop) to make sure Dexter never gets caught and to ensure that Dexter kills only other killers. Harry also trained Dexter in how to interact convincingly with other people despite his dissociative mental illness, which Harry believed to be psychopathy, arising from Dexter witnessing the brutal murder of his biological mother, Laura Moser.
