Cassidy falls in love with a graduate student of forensic science at Syracuse University, named Gilbert Edmond, and while she believes that the story of the Duchess was conjured by Sustah’s imagination, Cassidy convinces Gilbert to explore the historical accounting of events from her great-grandmother’s diary. In his dissertation called The Secret Sect of the Double Duchess, Gilbert disproves Sustah’s fantasy world as a child-like misinterpretation of real-life science, astronomy and physics and purports that the Duchess did actually exist. The evidence he uncovers supports the existence of Duchess Marion in historical scraps of documents from France, Canada and the United States. Cassidy and the graduate student obtain the necessary permits to exhume the grave of the Duchess, where they discover the artifacts buried by Bean and supporting DNA evidence that validates once and for all, the authenticity of the story written by her great-grandmother. Sustah’s diary is published as The Bohemians and is widely read as a work of fantasy fiction. Sustah refers to the Duchess as Princess Trikaya in her diary and Marion Chasseresse enters modern culture under this pseudonym.
