Llamas on the Loose — Jeri Massi

Doc Ericson has just started a llama farm, north of Peabody, Wisconsin, and he asks Penny, Jack, and Scruggs to help out. As soon as they get there, however, strange things begin to happen. Who let the llamas run loose? Is somebody trying to make trouble for Doc Ericson and his llamas? And what about that telescope they discovered? Could it be watching them?

When Jean arrives on the scene, Penny and Jack aren't at all sure they want their shy little sister hanging around. But Scruggs has some surprising things to say about that, and they end up working together as a team to solve the mystery.
