The Laughing Corpse (Anita Blake, Vampire Hunter, Book 2)

Harold Gaynor offers Anita Blake a million dollars to raise a 300-year-old zombie. Knowing it means a human sacrifice will be necessary, Anita turns him down. But when dead bodies start turning up, she realizes that someone else has raised Harold's zombie--and that the zombie is a killer. Anita pits her power against the zombie and the voodoo priestess who controls it. Notice to Hollywood: forget Buffy the Vampire Slayer; Anita Blake is the real thing.
