In Nancy Drew: The Haunted Carousel, Nancy must investigate a series of mishaps--including a missing horse and a malfunctioning roller coaster--that have occurred at the Captain's Cove Amusement Park. While the park is closed, you'll guide Nancy as she interacts with several workers still at the site, including the park's bookkeeper, the chief engineer, the security officer, and the park's art director. Nancy can only discover the truth behind the haunted carousel after solving a series of puzzles and avoiding several deadly traps.
