Constance Castaigne's name is found written in a copy of The King In Yellow at Coastal State Prison, in the story The River of Night's Dreaming. She was presumably a patient here when it was a private sanitarium, sometime around the end of the nineteenth century. The warden supervisor links the name (or at least the name Castaigne) with a scandal at the turn of the century, though isn't quite sure of the events. A murderess? A suicide?
The character Cassilda Archer escapes and, upon meeting Mrs Castaine and Camilla begins to adopt the role of Constance. Her final actions may repeat the genuine actions of Constance... A murderess? A suicide?
Prior to her murder of Mrs Castaigne the older lady tells 'Constance' that she's dead, to which Cassilda/Constance tells her she found a way back.

The name 'Constance Castaigne' is, of course, the name Constance Hawberk from The Repairer of Reputations would have taken had she married Louis Castaigne. It seems unlikely that this is the same person since, obviously, her own mother would be a Hawberk, not a Castaigne (although both families appear to have been linked to scandals). However, should Mrs Castaigne and her maid be delusion constructs, based upon the discover of the name in a copy of the play, and should Hildred Castaigne's alternate 1920s be a similar delusional construct imagined in the 1890s, there's a chance that the two are the same, that the scandal mentioned is linked, and that Constance suffered some sort of breakdown after her marriage.
