The Mystery of the Stolen Painting

Ethan and Ella are excited to get to Paris-they've only ever seen pictures of the Eiffel Tower! After arriving, the twins receive an email from their beloved Grandpa Harry. He tells them that there's a secret bakery near the Louvre museum-so secret, in fact, that you need a password to get inside. Lucky for the twins, their dad wants to take them to see some artwork at the Louvre. But while they're browsing paintings at the museum, alarms suddenly go off, the building is evacuated, and tons of police show up outside. A painting has been stolen! And Ethan and Ella are on the case! Can they manage to find the stolen painting and the secret bakery without giving themselves away?
