The Repairer of Reputations

From The Yellow Site

This story is set in a 1920s that never was (the story was written in the 1890s), and is a tale told from the point of view of Hildred Castaigne who, with the help of the 'Repairer of Reputations', Mr. Wilde, seeks to be claimed as The Last King of The Imperial Dynasty of America, and that his cousin Louis Castaigne stands in his way. The story reveals, over time, that Hildred has both read The King in Yellow and suffered a nasty fall, both of which are, it is suggested, in part way responsible for his delusions of grandeur and his attempts to ensure his ascension to the throne.
