Comment: because the subject passes  without too much trouble whatsoever. She was a key part of the The Mayerling Incident as the person the Crown Prince originally intended to enter into a suicide pact with. The baroness (with whom he did eventually commit suicide) was his "second choice". The whole thing has been the subject of a number of books, plays, ballets and movies, most named after the hunting lodge, Mayerling, where they died (see Mayerling (disambiguation)). Beyond popular culture dramatisations, the incident (and her part, in addition to her relationship with the Crown Prince) has been covered in detail in a number of books including http://books.google.com.au/books?id=0YDRAAAAMAAJ& ''Rudolph, the tragedy of Mayerling'' by Károly Lónyay (1949) and http://books.google.com.au/books?id=WGhXXGOyGG0C& ''Mistresses: Domestic Scandals of Nineteenth Century Monarchs'' by Betty Kelen (1966). R. H. Bruce Lockhart called her, ''"the real love of his life"'' in http://books.google.com.au/books?id=dXLRAAAAMAAJ& ''Your England'' (1955). There's more than enough there, I think
