Inspired by Nancys clue gathering, Amy hones her own sleuthing skills when one of her mothers patients, a Saint Bernard puppy, disappears. The mystery is lighta trail of fresh paw prints makes it obvious the dog hasnt wandered farbut Amys plan to retrieve the runaway pup reveals sharp thinking. The puppys grateful owner recruits Amy and her friends to help her open an animal shelter in her barn, which they name the Critter Club, setting the stage for future escapades. Despite a few clichés (Light bulbs went off in her head), Barkleys writing is crisp, with punchy dialogue, concise sentences, and a swift pace.
