Murder on Marble Row

This story was very convoluted and hard to figure out, although I did guess the ending pretty early. I just didn't know how it would work out. What a messed up family! I kept thinking they could have gone on some crazy talk show if it were a different time. I could just see that family talking to Dr. Phil. I have to say it was weird how Sarah and her mother suddenly seemed like the same character in this book when they have always been very different. Suddenly, Mrs. Dekker is out running around brazenly interrogating people in the sketchier parts of town with Sarah. It was a weird shift. I know they are mother and daughter but suddenly they are acting like twins. I did like the ending after the conclusion of the mystery.
