âI don't do my job to catch the bad guys. Why would I want to do that? No, my job is to make order out of chaosâ¦â Since first appearing in 2006, Dexter Morgan's double life as Miami Metro's blood spatter analyst by day and vigilante serial killer by night has made Dexter one of television's most compelling antiheroes. Created by our design team, this natural T-shirt features a graphic inspired by the infamous "Bay Harbor Butcher" investigation â one of the defining storylines from the early seasons that fans will recognise instantly.
