This book based on a true story is a historical mystery/courtroom drama with a bit of a paranormal twist.

Annie sent to a convent to deliver a child she bore out of wedlock has her baby taken away and as she wakes get back, she will do what it takes to get the money needed. She becomes a "companion" for men in several houses and is called Bessie. She will one day meet Abe Rothschild, a smooth taking man with sweet promises of a better life for her one day.
But she will be betrayed by this man in the study way.

I thought the story was unique in where it took Bessie after Abe's betrayal. Without giving too much away, I would just say that Bessie had a big part in trying to get him to be punished for what he did.
