The murder code

When Detective Andy Hicks examines the faceless corpse of Vicki Gibson, he clings to his philosophy that every murder has an explanation, even something as senseless as beating a young woman to death with a hammer. The similar murder of a homeless man further tests Hicks' belief and distances him from his pregnant wife. After more bludgeoned bodies appear, a pattern emerges that includes isolated locations, easy prey and a killer dressed in black who sends a letter to Hicks, taunting him that even he won't be able to crack the code the killer has generated.
