Showtime's latest poster and trailer for Season 8Dexter teases the death of Michael C. Hall's title character. While the story line is certainly "under wraps" until the season premiere, "A Beautiful Day", Dexter Morgan himself is seen under a sheet of plastic wrap in this one-sheet. Does this mean that Miami Metro's blood splatter expert will finally meet his maker, after sending so many others to the grave? We'll see when the final season debuts Sunday, June 30 at 9 PM ET on Showtime. In the meantime, check out the video, which also includes footage from Showtime's new series Ray Donovan, and this ominous promo art.
