Blood Slide Boxes are objects in the Showtime series DEXTER, Dexter Novels, and Dexter Early Cuts. They served as Trophy Cases that housed the blood slides that Dexter Morgan collected from many of his victims. Box One was used prior to the end of Season Two. It contained forty-six blood slides when it was stolen (confirmed by Dexter in "There's Something About Harry.") Dexter recovers it from Leon Prater's Trophy Collection in "And Justice For All..." of Dexter: Resurrection. Box Two was used from Season Three to Season Seven. It contained forty-three blood slides when it was destroyed. Box Three was used in Dexter: Resurrection. So far, it only contains two blood slides, albeit with two people sharing one of the slides.
