It’s the start of term at Winchesterfield-Downsfordvale, and Alice-Miranda and her friends are over the moon to learn about one of the school’s new charity projects—they are going to become the proud carers of a dog rescued from a nearby pound! To add to the excitement, there are whispers of a wedding between their two favorite teachers. Meanwhile, the local village is about to host the country’s largest dog show—however, at the last moment the grounds are deemed unfit for competition. The school is called upon as a replacement venue, and preparations head into overdrive. Along with the dog show come a number of bizarre characters—some are strange, while some are just downright unpleasant. While walking the school’s new dog, Alice-Miranda and Millie stumble upon something very worrying and will have to act fast in order to save the day!
