Rusty Shovels

He is known simply as "Digger". A young woman vanishes and a week later an open grave is discovered in a neighboring cemetery with her name on it. But there is no body, and curiously, no dirt left behind from the open grave. It is a baffling case that attracts the attention of an up and coming FBI agent named James Hunt, who follows a series of these disturbing and mysterious cases throughout the course of his career. The cases mount and eventually become the longest unsolved cases in FBI history. Yet not a single victim is found. Is Digger an actual serial killer or something from beyond the grave? Perhaps James Hunt will find out or perhaps Digger find him?
