Showtime has dropped a new trailer for Dexter as the critically praised series turns 10.

Dexter starred Michael C. Hall in his Golden Globe- and SAG Award-winning role as Dexter Morgan, a complicated and conflicted blood-spatter expert for the Miami Metro police department, with his own twisted sense of justice as he spends his days solving crimes and nights committing them. Named one of the best-written series of all time by the Writers Guild of America, the 2006-13 series featured a ensemble cast including Julie Benz, Jennifer Carpenter, Aimee Garcia, Desmond Harrington, Erik King, C.S. Lee, Geoff Pierson, Lauren Vélez, David Zayas and James Remar.

To mark the show’s 10-year anniversary, Showtime will give fans a chance to vote on their favorite episodes on the premium cabler’s website over a four-week period, culminating in a #Dexter10 Fan Marathon with the top 10 picks on Saturday, October 1. Showtime also will debut a new Dexter mobile game for Android and iOS devices on Halloween.

Produced by Showtime, Dexter was executive produced by John Goldwyn, Sara Colleton, consultant Clyde Phillips, Chip Johannessen, Scott Buck, Manny Coto, Tim Schlattmann, Wendy West, Jace Richdale, Charles H. Eglee, Melissa Rosenberg, Daniel Cerone and Hall. Dexter was developed for television by James Manos Jr.
