Instruct: Classify Amazon reviews into positive or negative sentiment
Query: A far cry from her usual level of entertainment...

If this is what Otto Penzsler feels is "non-stop action," I'm going to have to pay less attention to his reviews. I agree with Amazon's review, which refers to the "plodding pace." I could barely finish this book, and wouldn't have if it weren't Sue Grafton. The plot was so thin I figured it out immediately, and it was so easy to see through Mariah that I couldn't believe Grafton had the nerve to make it so obvious. I have greatly enjoyed all the books in the series up until now, but in my opinion, this is by far the worst. Very difficult to care about any of the colorless characters, and I found it hard to like even Kinsey in this book. If this were Grafton's first novel in the series it would go nowhere. Sorry, Sue!
