Autopsy: A Scarpetta Novel

I checked out this book with high expectations, having read other books by Cornwell, only to find such a jumble of poorly written pages that I gave up on it about a quarter of the way through. My main complaint is that paragraph after paragraph, page after page, sentences that should stand on their own are connected by the conjunction "and". Where on earth were her proofreaders? Where was her editor? Where, for goodness sake, was Patricia Cornwell, the best-selling writer? The Patricia Cornwell I've read and loved before wouldn't come near this mess. Worst of all, why did the book ever reach the shelves?
