Mary Zimmerman’s The Secret in the Wings adapts a group of lesser-known fairy tales to create a theatrical work that sets their dark mystery against her signature wit and humor. The play opens as a married couple leave their young daughter, Audrey, with the babysitter for the evening as they head out to a party. The couple sees a genial, avuncular babysitter, but Audrey sees a hideous ogre with a spiny tail who has obvious plans to devour her.
