The Sword Is Whet — William Crow Johnson

Sheriff Earl (Tip) Tungate must learn who is behind a series of ghastly murders in normally peaceful Sedalia, Indiana, and stop them. Mysteriously, the FBI and the local prosecutor order him off the first case, but he persists. Then he learns their reasons. These are not just murders, but part of a terrifying terrorist plot aimed at the entire United States, not just Sedalia. And he knows what the FBI doesn't. Only he can stop it.
