Over the year, Dexter Morgan has squared off against an ice truck killer; a detective that learned his secret; an ambitious, shady lawyer; and a serial-killer family man.
But the title character of Showtime's Dexter will face a new foe on season five, as teased in the poster below: his own guilty conscience, which is a result of Rita's gruesome murder.
The drama returns with new episodes on September 26. Visit our Dexter spoilers section for more insight on what's to come.
