Big Worry in Wonderland

There's big excitement for Nancy, Bess and George and their entire third grade class. They are putting on a production of Alice in Wonderland. They are rehearsing their lines, and all seems to be going well for the opening of the play. But, how can you have a Mad Hatter without a Hat? Nancy can't figure out who took it, and they have to have it back. Seeing somebody reach out for it is not proof of guilt. And, Nancy has troubles of her own because the Mad Hatter wants to help her solve the case -- and Bess and George just don't care for him! Will solving this case break up her wonderful friendships? Nancy had better get out her blue notebook and start eliminating suspects as fast as she can, or there will be even more Big Worry in Wonderland!
