Just finished reading Dearly Devoted Dexter and have really enjoyed this novel. If you know the TV series Dexter then you will know about the main character, but if you don't then some explanation is needed.
Dexter is a blood splatter analyst for the police, but his real character comes out at night when he is a serial killer who hunts down and kills other serial killers.
The books a written with quite a light touch and contain some black humour that the TV series doesn't convey.
Well worth reading for fans of mystry novels with a twist, and fans of the TV show.
