In the wake of Ellen's disappearance, Dexter fears that Miguel may have strayed from Harry's code and killed her, in spite of what Dexter tried to teach him. Dexter tries to prove that he is still in control to Miguel, but realizes that Miguel had been dishonest from the beginning of their friendship. Rita confronts Miguel about his actions when Sylvia becomes convinced that Miguel is having an affair. Debra realizes that Anton has been kidnapped by The Skinner, whom the police believe to be George King. Unfortunately, the only witness, King's employee Mario, is too afraid to talk to the police.
what seemed to be a slow series 3 has now come together to make another amazing series, different to the previous 2 but not at all dull as I've read in some comments on the web. This is by far the best writing and acting for a series and gives any film based on this genre a real lesson in screen writing. I wasn't sure where the relationship with Miguel Prado was going but it held reason for being there, I just wasn't sure why. The skinner was a very good distraction from the real monster of series 3. MC Hall sure now's a good series when he reads one! I hope there will be another series on the cards. Will Dexter become boring after 3 series? I don't think so, but I'm sure its worth finding out....
