The Case of the Portrait Vandal (Museum Mysteries)

There's a vandal in the Capitol City Museum of American History, and he or she is intent on defacing priceless artifacts. Raining Sam, the son of the Head of Educational Programs and local Ojibwe tibe member, is determined to get to the bottom of things before anything else can be destroyed. But when Raining himself is considered a suspect, he and his friends must race against the clock to unmask the real culprit and solve the museum mystery before it's too late.
