Sneaking Suspicions — Carolyn Coman

The return of Ray any Ivy, the unforgettable characters from The Big House. When Ray and Ivy's father, Dan, proposes a road trip to visit a long-lost relative, neither of them is particularly excited. Then he shows them the giant ruby he discovered in a hollowed-out book in the library. So they load up the limousine and with Veddy, their trusted chauffeur, they hit the road. They don't get far before the plans change and Ivy has lots of doubts about what's going on. Is Dan on the up-and-up? Is the ruby real? How they meet Wolfgang the counterfeiter, race each other on a roller coaster,explore a real gem mine, and end up stranded in the middle of a swamp surrounded by alligators makes a rollicking romp of a story.
