A Thief in the Theater by Sarah Masters Buckey

In this story Kit spends a week of her summer vacation volunteering at the local theater. She also wants to write a newspaper article about a play that's opening soon. But the day before the play is opening, a thief crashes into the play room and ruins the whole set-up. Kit and her friends are on a mission to find where the thief is. I like this book because this book has suspense and mystery.
