Melina Rosi, the curator of the Phidias Cultural Center in Greece, hires Nancy Drew to assist with the museum's most anticipated event of the year. Persephone in Winter, a play about the myth of Persephone, is being performed in the amphitheater to drum up publicity for the new Life in Ancient Greece exhibit. However, artifacts from the exhibit are mysteriously disappearing. Are these mishaps connected to the amphitheater's upcoming performance, or is an unseen villain pulling strings behind the scenes?
