If you want to read more about her, you should certainly consider purchasing the excellent book, Courtesans by Katie Hickman. A fabulously informative yet gossipy read!
Alternatively, you could seek out Cora's very own memoirs (now sadly out of print) - I am so fascinated with her that I have done just this and cannot wait to read it. Sounds as though it may be incredibly scandalous...
The erotic reminiscences of the best known courtesan of the Second Empire, revealing the most intimate secrets of lovers from every level of society-even, she claims, the Emporer Napoleon III himself. Recently William Blatchford discovered these authentic memoirs in the private library of a German collector. Cora Pearl discusses in the most graphic detail the sexual prowess and predilections of lovers famous and humble; tells of her erotic exploits on horseback; invents, then ignores, the motto "jamais avec les domestiques:; and describes her presentation at dinner, cream-decked, as an exquisite final dish.
How marvellous. :)
