Killer Instinct

A book has been on my mind recently, mostly because I'm currently reading it.  The book in question is Darkly Dreaming Dexter, the book that inspired the hit Showtime series, Dexter.  As of this blog, I'm only about half way through it.  (No spoilers, please.  I'll probably review it at a later date/when I'm done reading it.)  If you don't know the story or series, I'll give you a brief rundown.  The main character is Dexter, a blood splatter specialist for the Miami-Dade Police Department.  If there's blood on a scene, Dexter can tell you how it got there, at least from a scientific standpoint.  However, Dexter also has a dark secret:  he's a serial killer.  He has a bit of a conscience, though, as he only kills people whom he knows are also serial killers.  

I'd say he cut himself shaving, but he obviously still has a beard.
