The Quest Of The Missing Map (Nancy Drew, Bk. 19)

"No! I won't go there!" seven-year-old Trixie Chatham cries out. "The Ship Cottage is haunted!" Prompted by her concern for the frightened child, Nancy investigates the small studio on the Chatham estate. What the astute young detective discovers leads her to believe that there is a connection between the mysterious occurrences at Ship Cottage and her search for a treasure island. Constantly beset by danger and intrigue, Nancy courageously outwits her enemies and solves one of the most challenging cases in her career as a teen-age investigator.
