A trio of cousins researching a family history project encounter a leprechaun who gives them a badge to a Magical Mousegate. The Mousegate is in Walt Disney World, and will transport them to an old West Secret Service counterfeiting case. The trio is embedded in the consciousness of the three main characters in the book and follow the case from beginning to end, while experiencing life through their character's eyes, heart and mind. While the Prologue and Epilogue detail the actions of the teens, the rest of the book is a classic old style Western mystery. There are bank robbers, crooked politicians, a love interest, and a shootout. The book would be enjoyable to early to mid-teen readers, boys and girls alike, as well as adults. It is an unusual adventure, since it details the actions of Secret Service operatives while investigating counterfeit currency in the Old West in 1898.
