Get Rufus!

In the remote Great Smoky Mountains of North Carolina, the sheriff of Jackson County, way back around 1917, had just two words when someone was needed to restore law and order - "get Rufus!" - and Rufus would come a ridin' into Sylva, the county seat, on his female mule, Fred, and then the fur would fly and the bad guys get their comeuppance.

"A delight, dishing up charm, adventure, and a delightful mountain flavor, all at the same time. Bob Terrell knows his way around a story - and there's a female mule named Fred that you're going to lose your heart to."
