A Woman's Burden

They mysteries are unravelled slowly and the murder does not happen until you are in the middle of the book. The female main character has a mysterious past, she is saintly and good, very hard to pick the killer as there are several villainous characters, but you wont be surprised! part of the mystery surrounds who will marry who, the disappearance of a will and who is hiding what but I cannot really say much more as I will be spoiling it.
