Review: This was the first Patricia Cornwell book I have read. She is a compelling storyteller, and she obviously possesses great knowledge of the subject matter. I do admit to finishing the book in a two-day period, but it was more to get to the inevitable final showdown between Scarpetta and the killer. Scarpetta and some of her cronies are characterized well, but the killer seemed a bit stereotypical. I don't believe in reading ahead and spoiling the surprise, but in this case I skipped some detailed sections to find out how the killer would be stopped in his tracks.Since reading this book, I have read Cause of Death by Cornwell and would rate that book slightly higher than this one. This book is not her best that I've read so far, but it wouldn't prevent me from reading another one.This is a good, focused, and knowledgable writer who does not need to fall back on unbelievable killers and sensantional plot devices to tell an imaginative story.

Review: I first saw this ad before Christmas, and decided to check back later. I have checked 7 times since then and the glasses are never in stock, but I should "Get in line"?I don't shop at Amazon in order to be "in line" for 2 months.Does this stuff exist or is simply a method to get you "on the line"?
