Query: dissapointing

I was very dissapointed in this book. I generally feel that Cornwell writes resonably well with a plot that provides enough twists and turns to keep things interesting for a entertaining read. There was no tense build-up to a surprising or exciting ending, which is what I want in a crime novel. Her writing is generally not bad, but her editor must have been asleep for this one. I don't require perfect writing from the authors I read, but in this book, there were enough instances of awkward sentences and bad grammar that it became distracting. In addition, her characters are becoming thin and tiresome. Elizabeth George is an example of a mystery writer whose characters actually grow from book to book and when I pick up a new book of hers, I'm interested in what will become of the characters next. Ms. Cornwell's characters have become way too predictable and one-dimensional.
