While Connie awaits her undeserved punishment, a ghost appears to offer a bargain. The spirit is none other than Scarlett Castiel, a noblewoman once praised for her beauty, lineage, and undeniable charisma-and executed some ten years earlier for her wicked deeds. When Connie accepts this proposal, she is possessed by the infamous spirit who instantly turns the tide on her tormenter, thus saving the hapless girl from her miserable fate.
