Plot summary

Nancy and her friends are invited on a ghost-hunting tour, visiting various locations reputed to be haunted. They gather clues that point to a more mundane explanation.

Nancy uncovers a gang of thieves that are stealing rare shells from collectors. Some of these shells are no longer rare, such as Conus gloriamaris.[1]

Helen, Nancy's friend from the earliest books in the series, makes a rare appearance. Previously Helen Corning, she is now married to Jim Archer and goes by Helen Archer.[2]
