The Case of the Empty Crates (Hardcover)

The Air and Space Museum is adding a new exhibit, and Amal Farah and her friends get to attend the grand opening! But before the new exhibit goes live, some of the items go missing. This won't be good-the exhibit is funded by a rich local businessman, and without the objects to show, the exhibit can't open. Did another museum take the object, trying to make up for missing funding? Was it a thief interested in telescopes? Or someone else? Amal and her friends are determined to solve this crazy mystery!
