Example Input: Last year I found this book and once I opened it I could not put it down. Bugliosi is excellent at bringing the details to life on the page. Not only do we get a first hand account of the trial, but he also explains much of the legal process in very clear and understandable terminology. I am now a fan of his work and will be reading everything I can of his.
Example Output: Positive
