When Milton Grone turns up dead in tiny River Bend, Illinois, nearly all the would-be suspects have the perfect alibi: attending Thursday night's town meeting. And as Milton was hardly beloved, plenty of folks had a reason to do him in ...

Grone's next-door neighbor was furious about a fence that encroached on her property, among other wicked deeds. A pair of zealous tree huggers wanted Grone's hide for selling a parcel of pristine land to a water park. Grone's current and ex-wife both wanted a cut of the profits, which Grone seemed unwilling to share. Even the town preacher knew Grone's soul was beyond saving.

Though most of River Bend would rather reward the killer than hang him, Sheriff Biddle's not about to let this one go … and neither is Helen Evans. With a penchant for puzzles and an ear for innuendo, Helen quickly fingers the culprit before Biddle puts the wrong suspect in jail.
