Recently divorced, Anna decides to cheer herself up by retracing a journey her great grandmother made in the nineteenth century: a Nile cruise from Luxor to the Valley of the Kings. Anna carries with her on the voyage two mementoes of her great-grandmother Louisa: an ancient Egyptian scent bottle, and the diary of that original Nile cruise, which has lain unread for a hundred years. As she follows in Louisa's footsteps, Anna discovers in the diary the chilling secret of the scent bottle and is pursued by the same terrifying spectres as her great grandmother.
