Saddle up for this first volume in a spin-off series starring favorite characters from DiCamillo's "New York Times"-bestselling Mercy Watson books. Leroy Ninker has a hat, a lasso, and boots. What he doesn't have is a horse--until he meets Maybelline, and then it's love at first sight.

Visiting a re-creation of a frontier town where they enjoy many cowboy-themed activities, the Aldens are on the case when a vandal commits dangerous pranks that threaten to ruin the Wild West show
