Sophie see's a woman in a window at school and drags two of her friends. The women needs help solving a twenty year old mystery that may reunite her with her estranged daughter. In addition to the mystery there are boy problems, a Great Expectations skit and an evil deacon.
This was a cute little mystery. There wasn't anything super exciting about it. If you think about it enough a couple chapters in and you can figure out who dunnit. The girls are sweet and likable as are many of the other characters (except the bad guy of course.)
My one complaint is that there was math. The girls need to solve a series of puzzles and the whole thing leads to some plane geometry. Oh there were vicious vicious flashbacks. I was not happy.
There is also a slightly religious aspect to the entire thing, however it's mostly from a historical perspective and no one's being beat over the head with anything. All of the parts discussed end up being relevent to the story.
