Countess Elizabeth Bathory

This book was vague about the real life details of the Hungarian Countess Elizabeth Bathory AKA “the blood countess” or “Bloody Countess” so I found it disappointing to read.
Some people believe she was a vampire, a possible witch but she was definitely a real person, that was sadistic and evil due to learning about torture methods and witchcraft by one of her servants Darvulia.
This book is more of a reference book rather than a informative account of the life of Elizabeth Bathory, so I will read other books that are more detailed to find out more about her.
I don't understand why more accurate accounts of her life were not translated into English, since I would be interested in reading about it.

This book is just a overview of the life and what possibly lead Elizabeth Bathory to torture, mutilate and murder/bathe in the blood/possibly drink the blood of servants that were peasants or nobility for her own sick and sadistic pleasure. I would recommend this book to anyone that has never heard of Elizabeth Bathory, and they don't know anything about her or Vlad Tepes (Prince of Wallachia, Transylvania in Romania)
I didn't receive the version of the book that I wanted (Elizabeth Bathory in a red dress, the pages were printed in a waythat it isn't aligned properly so that is another reason I was disappointed with this book) :/
