In 2009 Dexter had a season long arc involving a mass murderer known as "The Trinity Killer." Here in tonight's Castle they had "The Triple Killer." Both men killed in threes. While it is clear that they ripped the storyline from the popular Showtime series, I still have to say that this was a thoroughly entertaining episode of ABC's only real cop show worth watching. Castle was on his game comedically, but thankfully they also had some serious moments in the episode to put over the vitality of this murderer.
Good episode, definitely turned me into a Castle fan with this one.
