The sunset of the mighty English empire cast its blood-red glow over the great Falcon manor of Kingsmead. While the Falcon men were away fighting and dying on the battlefields of World War I, the most ruthless and voracious of the Falcon women were seizing control of the Falcon fate at home.

There was Leah, who had done so much evil in her life, and now was fearful of the satanic forces she had summoned forth but could no longer control. There was her niece, Levanah, mistress of all the black arts, supreme in her power to seduce and corrupt all around her. There were the men who were their helpless pawns, the children who were their pitiful puppets - and the young girl whose uncanny powers and indomitable courage made her the last hope to save the Falcon name and the Falcon honor from the infernal triumph of darkness.
