The Vampire Who Played Dead — J.R. Rain

Two years ago, a woman is murdered in cold blood. Now a son she'd given up for adoption returns to claim his inheritance. To verify his claim, a Dna test is ordered. Except there's one problem. Her grave is empty. Spinoza is a private investigator who specializes in finding the missing. He's good at what he does. Damn good. But he's also a recovering alcoholic and a royal mess. Hired to find the missing body, Spinoza will follow a set of clues that leads him to the unthinkable, a world of nightmares and dreamscapes. A world inhabited by the living and the dead.
