Query: Very Disappointing

I have read most of Patricia Cornwell's books and I have a hard time believing that the characters just seem to stand still and don't grow in any way. Marino seems to be a cartoon character built upon every generalization of middle-aged overweight men you ever heard of, Kay Scarpetta just can't be that unaware (we all knew the suspect was outside the door and who was stealing in the morgue). A book about Lucy could be very interesting at this point, she seems to have growth potential. I was disappointed with the overall story and the complete lack of character growth - no one here seems to have learned anything from their past.
