Dom is excited to join her friend, Steph, for a mini vacation. They are going to visit Steph's grandmother in Virginia, where Dom hopes they can continue to have a lot of fun adventures. As soon as they arrive, they find that Gran's neighbors have lost their goat! There are some mysterious footprints near the goat pen that lead to the marsh. Dom decides to use the methods of her favorite detective, Sherlock Holmes--observing the basics, using all her senses, and talking it through with her trusty friend--to try and bring the little goat back home.
