Greenhill Police chief Buck Peters, the deacon of his local church, investigates the murder the "town tramp." The prime suspect is Kip Belton, the police commissioner, whose alibi is that he was with his wife, Lacey, at the time of the killing. There's just one problem with that story. Buck knows it's a lie...because when the murder happened, the Chief was having sex with Lacey in Belton's backyard. And that's only the beginning of Buck's problems.
