She was not an easy woman to categorize or to explain. If I've ever known anyone in my life, man or woman, who was unique, it was she. There was nobody like her before or since. Never will be. In every way. In talent, in looks, in character, in temperament. Everything. There sure wasn't anybody who didn't fall under her spell.
