Query: Very Gross book

I didn't even know things like this went on. It totally grossed me out.How could anyone with an ounce of self esteem allow "M" to do those things to her. And Nora seemed like a strong, well adjusted heroine, but her decline into S & M, was totally unrealistic to me. The book did keep you guessing however as to who committed the crime, but this book is too "hardcore" for my tastes.
