Dexter returns to US TV screens for season six this September and Showtime have today released some fabulous sneak peek pictures of it’s upcoming episodes.

As well as all our old favourite characters, fans can get their first glimpse of Dexter newcomers Edward James Olmos – who will play this season’s bad guy and Colin Hanks – who takes on the role of Travis, a highly intelligent young expert on ancient artefacts.

Manny Coto, executive producer has recently revealed that viewers can look forward to Dexter returning to his same old self this season, saying that he has finally stopped grieving for his dead wife Rita.

It has also been reported that he will be a ‘more evolved serial killer’, when the season jumps forward a year.
