He's smart. He's lovable. He's Dexter Morgan, America's favorite serial killer, who spends his days solving crimes and nights committing them.

The name of the main character, "Dexter," is also a Latin word meaning "right hand." The implied complement is the Latin for "left hand," "sinister," reflecting his hidden dark side. In 2010, author Jeff Lindsay confirmed at a book signing in Edinburgh that he chose the name Dexter because it was the opposite of "sinister", reflecting the character's surface normality.
Season 1 was heavily based on Jeff Lindsay's novel called 'Darkly Dreaming Dexter'. The following seasons vaguely reference the sequels of the novel.
