Chapter IX, The Infatuation of Mary Vetsera
Marie Larisch (1858-1940)
Countess Marie Larisch, My Past, G.P. Putnam's Sons (1913), pp. 207-208
Technically, since the Count and Countess Larisch divorced in 1896, the Countess was not so entitled. However, she was created Freiin (Baroness) von Wallersee shortly after her birth and the signature Marie Wallersee appeared on the book cover above the block letters "COUNTESS MARIE LARISCH." She was a member of Bavaria's Wittelsbach family. At the time of writing the book she was married to Otto Brucks.
My Past had the dedication:
Actually, ffoulkes was the ghostwriter.
Mrs. Maude Mary Chester ffoulkes
in gratitude for her kindness in helping me to prepare
these reminiscences for publication
The Countess wrote another biography:
