[EX Q]: Like all of her Scarpetta mystery novels, Patricia Cornwell has proven again that she must have been one dynamite of a Coroner when she was practicing. She has a wealth of information in her books and it is so interesting to follow as she progresses to solving the mystery. I've never enjoyed reading as much as when I pick up a Cornwell novel.
[EX A]: Positive

[EX Q]: why am I being asked to review a product I didn't purchase. Need to fix the system or allow me to delete the request.
[EX A]: Negative

[EX Q]: I am pleased with this item. It would be helpful if it were slightly longer for my torso, but everyone is different of course.I wear it a lot and it has held up well. It is rubbery, so a base layer is important or you may break out when your body perspires.
[EX A]:
Positive
