Inside an enchanted castle, there’s a closet—a closet with one hundred magical dresses that only Darling Dimple can wear. Each one disguises her as somebody else.

It turns out that Darling needs disguises. A thief is on the loose! Someone is causing an uproar among the servants—moving things around, stealing clothes from the laundry, and even pocketing Princess Mariposa’s jewels. Then Darling and her friend Roger think they spot a ghost roaming the halls. Could the culprit be a spirit? Can Darling and Roger get to the bottom of it all? With the help of the one hundred dresses, there just might be a ghost of a chance.
