Miss Ruffles inherits everything

the long version

"Rich and flamboyant Honeybelle Hensley, the most colorful character in Mule Stop, Texas, dies a suspicious death and enrages the whole town by leaving her worldly fortune to the most undeserving recipient-her dog. The incorrigible Miss Ruffles is a Texas Cattle Cur, not a cuddly lapdog, and when Honeybelle was alive, Miss Ruffles liked nothing better than digging up Honeybelle's famous rose garden after breakfast, chasing off the UPS man before lunch and terrorizing the many gentleman callers who came knocking at cocktail hour. But now Miss Ruffles is in danger, and it's up to Sunny McKillip, the unwilling dogsitter, to keep her safe."--
