New Jersey-born, former opera singer (contralto) and adventurer. She had a passionate but temporary relationship with the King of Bohemia while performing in Warsaw. When she heard the King was about to marry another noblewoman, she kept the photograph they once took together to take revenge on him or to protect herself. She is extremely intelligent and determined; capable of perceiving all the games of a detective. She even followed Sherlock Holmes to Baker Street in the disguise of a man and cheekily bid him good evening. She leaves the country by marrying the lawyer Godfrey Norton, but leaves behind a brilliant victory that leaves Holmes stunned with respect.
