Theodora “Theo” Tenpenny knows a lot about artwork. Her grandfather was an artist and worked as a security guard at the Metropolitan Museum of Art. Then, he passed away and left her a note telling her to “look under the egg.” What egg? Did he mean the painting that hangs in his art studio? It has a large egg on it. When she accidentally spills water on this painting, she finds that there is another painting; one that looks like it should be in a museum. How did her grandfather get this painting?  Did he do something illegal? Theo doesn’t know what to do. With the help of a new friend, Theo decides she must figure out what her grandfather did to get this painting and also clear his name if she needs to. This mystery has many twists and turns as well as some great information about art, World War II, and a special group called the Monuments Men.
