Too Late To Die - A Dan Rhodes Mystery. Dan Rhodes Mysteries, #1

Jeanne Clinton was a pretty and well-liked woman-though in her younger days she'd been known to be a bit wild. She married an older man and settled down to a quiet, respectable life. Now she's dead, brutally murdered in her home. Dan Rhodes, the thoughtful, hard-working sheriff of Blacklin County, Texas, has enough to worry about already: a rash of burglaries in town and an election coming up against a hotshot opponent.
Now he's got to find a killer among the residents of his little town-a wily killer, bound and determined not to be caught. The deeper Rhodes digs into the hearts and minds of his neighbors, the more secrets he turns up, and the more violence he encounters. But Rhodes doesn't give up easily. And neither does the killer.
