Query: What Happened???

I eagerly awaited the release of this in paper back having read all previous Instinct books! The previous books were so well researched, Jessica was smart, savy and knew her proceedure inside out. Nothing slipped past her and she outsmarted everyone!This book she is like a rookie patrolman. It's like someone else wrote this book and just filled it with shock value murder scenes.Oh Mr. Walker, this is such a disappointment!
