From the developer:
Mystery Tales: The Twilight World is a hidden object game for Mac OS. You and your daughter, Nancy, can't resist the lovely hotel just off the highway, especially after a long day on the open road. But just as the two of you get settled, your peaceful pause is shattered by a witch who abducts Nancy. You must travel to the Twilight World to stop the witch before she takes over your daughter's body.
