Dexter Morgan first sank his scalpel into the face of a terrified, plastic-wrapped victim on TV screens across the country seven years ago. Since then, Dexter has kept audiences simultaneously creeped out, fascinated, and strangely rooting for its serial killer with a heart of gold. Have there been ups and downs? Of course. No TV series runs for seven seasons without making a few mistakes. But even as reality-TV programs about the underbelly of South Florida continue to multiply, Dexter is still the best illustration of that old saying about Miami: "Sunny days, shady people." Loyal viewers of Dexter have watched plot lines about strippers, mobsters, and religious zealots. They've gotten to know drug addicts, corrupt politicians, and crooked cops. They've seen murders on Ocean Drive, in the Everglades, and even at Jimbo's. And in its final season, which begins June 30, anything could happen. There's a vacuum of power at the Miami Police Department after the death of Capt. Maria LaGuerta; Dexter's sister Deborah, who discovered her brother's "dark passenger" last season, is still dealing with icky yet fascinating romantic feelings for him; and of course, there's the issue of the dozens of people Dexter has killed throughout the series. Will he finally be made to pay for his crimes, or will America's best-loved murderer get the ultimate free pass? One thing is certain: It'll be fun finding out.
