The Mystery at the Moss-Covered Mansion is the eighteenth volume in the Nancy Drew Mystery Stories series published by Grosset & Dunlap, and was first published in 1941. The original text was written by ghostwriter Mildred Wirt Benson, based upon a plot outline from Stratemeyer Syndicate co-owner Harriet Stratemeyer Adams. The book's title was changed to Mystery of the Moss-Covered Mansion when it was revised in 1971, because the story is completely different and not much of the investigation takes place at the title location. In the original, many plots and much investigation all tie back to the same house deep in the forest, while Nancy helps her father locate an heiress, expose an impostor, investigate a murder, and look into strange screams at the mansion; none of the action in the original story took place in River Heights.
