Sam is wracked with nerves before his wedding, and one of his worries is that there will be a murder. There's always a murder whenever his Aunt Athena, an amateur sleuth and famous mystery author, visits, and when she attends their wedding on Martha's Vineyard it's no different. Now, besides trying to fit in with his new family, he has to contend with an uninvited hurricane, a murder, a haunted inn and not being able to find his dress shoes.
