Dexter – Season 4 Episode 6 : If I Had a Hammer

Armed with the disturbing knowledge that he shares just a little too much in common with Trinity, Dexter sets the wheels in motion to trap him in his own game.  Even more disturbing, this episode also offers yet another gratuitous glimpse of John Lithgow’s tookis.

Having identified the proverbial wolf in sheep’s clothing, Dex begins sitting in on services where Arthur is a deacon in a local parish.  (For those of you playing along at home, Trinity has now been named as “Arthur Miller” — which may be the greatest, most innocuous serial killer name ever.)

Dexter discovers even more about Trinity, lining up the evidence (courtesy of Lundy’s collection of books and papers on his 30-year obsession) and uncovers Arthur Miller’s family history.  Arthur’s 16-year-old sister was killed in a bathtub, his mother fell to her death, and his father was bludgeoned to death.  The string of events left Arthur an orphan with no family — yet another similarity that hits home with Dexter.
