You must understand how this author works. He takes everything, and I mean everything that he can find about the case, all court transcripts, all witness testimony, etc. and picks it apart. One word at a time. He doesn't decide the guilt or innocence. He allows the reader to make up their own mind with all of the evidence that he presents.
You will find out stuff that you never heard of, things that weren't allowed to be brought out in court. All of his books are written the same way and I think he is just great.
