The Lost Treasure of Tuckernuck

Eighty years ago, the founder of Tuckernuck Hall Intermediate School hid a treasure somewhere inside the school. Years later, the school is being shut down, and no one has found it. Until now. When Laurie and Bud stumble upon the first of a series of clues, they join forces to try to find the treasure before the school is demolished and the treasure is lost forever.
