The Ghost of Grey Fox Inn (Nancy Drew Diaries, Bk. 13) by Keene, Carolyn

Nancy and her friends find themselves at a haunted inn with a mystery to solve in this thirteenth book of the Nancy Drew Diaries, a fresh approach to the classic mystery series.

When Nancy and Bess accompany George to a cousin’s wedding in historic Charleston, South Carolina, they end up staying at an old inn near the family’s home with the rest of the guests. But when they begin hearing strange noises and witnessing unexplained phenomena at night - they soon discover that it’s one of Charleston’s most haunted hotels! When the wedding rings disappear during one of these spooky evenings, Nancy knows she’s got to get to the bottom of this ghostly mystery . . . before there isn’t a happily ever after.
