 By the end of the novel, Edgar learns (among other things) that he himself has been sleepwalking, that Clithero was indeed not involved in Waldegrave's murder, that Waldegrave was murdered by a Lenni Lenape Indian, perhaps one he himself had killed, and that he and his fiancée are both destined to inherit nothing.In the novel, both Clithero and Huntly are sleepwalkers, although at the beginning of the book Huntly does not realize it.Sleepwalking is prevalent in the story, and Brown uses this device to drive the plot of the novel.
