The Keys to Queens Court — Jeanne Hines

Mistress of terror...

Diane Forrest came as the bride of a man she barely knew to the fabulous mansion of Queenscourt. Industrial tycoon Duke Tarrant had swept her off her feet and wed her with the same burning passion and iron will that had broken down every barrier on his path to success.

Only at Queenscourt did Diane begin to learn the truth about this man she desperately loved, and this place she feared more with every passing night. She was not the first woman in Duke Tarrant's life, and the others had died suddenly, mysteriously, hideously. And she was not the first woman to be mistress of this great house. Another had ruled here before Diane...a heavenly beautiful, demonically possessed woman whom the world said was dead...a woman whose spirit Diane alone knew was alive, and seeking a vengeance straight from hell itself...
