Dexter in the dark

Is evil alive? Dr Jerry Halpern is trying to find out, studying for his PhD on the subject. Dexter Morgan, meanwhile, has a few wicked things of his own to contend with - no least, planning his wedding to Rita to complete his nice-guy disguise. But when a student of Halpern's is found murdered - seemingly sacrificed to an ancient god - and Dex is bought in as forensic analyst to help investigate, he releases he could be dealing with someone a whole lot more sinister than he is. Soon it seems the dark passenger in Dexter's head has gone into hiding. And when something creeps out your friendly neighbourhood serial killer, you know it's serious.
