This is what it says on the back: Ashley and I weren`t looking for a mystery when we visited the New York City Ballet. But when we whent backstage for a special tour, a mystery found us! The star ballerina`s sparkling diamond tiara was stolen-right under her nose. She couldn`t perform without it! Luckily the Trenchcoat Twins are always on there toes! We leaped into action to find the ballet bandit before opening night was ruined.
