I thought this book was written well and I was reading on this case recently. And I really liked the authors perspective on this case. And I took notes while reading this book and the conclusion of the book was basically a cop or investigator being part of this. The author has a good theory with Shipp being a part of it and I don't doubt he was a part of it. After reading this I feel as though this is a good book to read if you're studying the O.J simpson case. The theory was great but some parts of this theory seems as though it's missing pieces. All though I liked how the author connected the pieces together in a semi accurate way the story makes sense and I do believe that OJ in inoccent.
Most of the contemporary books about this case have at least a detail or two that is of interest, and that's true about Schulman's work as well. However, his theory is just way, way, way too implausible and too poorly-evidenced to be taken seriously, so any such details are really the book's only (meager) value.
