Isadora Klein

Tall, queenly, a perfect figure, a lovely mask-like face, with two wonderful Spanish eyes which looked murder at us both.
“She was, of course, the celebrated beauty. There was never a woman to touch her. She is pure Spanish, the real blood of the masterful Conquistadors, and her people have been leaders in Pernambuco for generations. She married the aged German sugar king, Klein, and presently found herself the richest as well as the most lovely widow upon earth. Then there was an interval of adventure when she pleased her own tastes. She had several lovers, and Douglas Maberley, one of the most striking men in London, was one of them.” (Sherlock Holmes)
