The Case of the Empty Crates

The Air and Space Museum is adding a new exhibition, and Amal Farah and her friends get to attend the grand opening! But before the new exhibition goes live, some of the items go missing. This won't be good - the exhibition is funded by a rich local businessman, and without the objects to show, the exhibition can't open. Did another museum take it, 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!
