A new episode of Dexter will be airing this weekend on October 10 and Showtime has released a sneak peek and a synopsis for the episode.

After weeks of mourning and transitioning to single fatherhood, Dexter (Michael C. Hall) is back to his old serial killing ways.  He attempts to hire a nanny for Harrison so he can continue to stalk and kill his next victim.  His latest target is Boyd Fowler (Shawn Hatosy), a "road kill janitor" with a proclivity for killing young women and disposing of their bodies in the Florida swamps.

But this seemingly hapless civil servant proves to be a more complex and sinister adversary, leaving Dexter with more questions than answers. Meanwhile, Debra, who takes the lead on a bizarre double homicide, is displeased when Batista suggests bringing in an annoying rookie officer who has her own theories on the case. Things heat up for Dexter when Quinn notices strange similarities between Trinity Killer suspect ‘Kyle Butler’ and Dexter Morgan.
