Plot summary

Nancy looks for a flight of the 99 steps in France to solve the mystery of a friend's strange dream. Before Nancy, Bess, and George leave the United States for France, a person calling himself Monsieur Neuf warns Nancy not to pursue her mission.

The girls arrive in Paris and join Nancy’s father, who is trying to find out who or what is causing wealthy financier Monsieur Leblanc to sell large amounts of securities.

Nancy determines that the case she is investigating involving the 99 steps is linked to the case her father is following. Nancy thinks that Monsieur Leblanc could be being blackmailed.

Startling discoveries convince the youth that Mr. Drew's case and her own mystery are linked by the 99 steps, and that a mysterious Arab has a strong hold over Leblanc. Nancy thinks it could be blackmail.

Nancy goes to an area in the Loire Valley to look for more clues, and Nancy, Bess, and George wind up in danger.

<i>The Mystery at the Moss-Covered Mansion</i> Nancy Drew 18, published 1941

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.
