Bloody Banquet

Somebody wants Walter dead. Again. He doesn't know who the strangers in town are, or what they are, and he sure as hell has no idea what this 'key' is that they're looking for, but apparently somebody told them he has it, and now it's the key, or his life.
As if life and death wasn't enough to worry about, a forlorn teenager has decided to make Walter her new best friend. Oh, and Percy's gotten in deep with a drug dealer who wants to use Walter's funeral home as a front.
Walter is beginning to understand why most ghouls live like hermits.
