Detective Michael Tabb knows the city of St. Louis inside and out. He has felt its true heart, as much as its dark underbelly: but he does not know who, in both the dark and light - is taking the lives of young girls. He only knows that their burned and broken bodies are washing ashore along the Mississippi River, never to return home. He wears the scars of the one time he got close. Now, he's living in the darkness himself, perhaps too deeply. His physical pain is matched only by the pain he feels each time another young girl goes missing or washes ashore. Self-medicating to both ward away and embrace this killer, he falls farther from his light. Truth be told, the closer he comes to death by his own hand, the closer he gets to solving the murders.
