This book published in 1996 shortly after the acquittal. It is actually a book about Darden and his life before and after the verdict. So, readers looking for a sustained thesis with supporting details why the jury was wrong should look elsewhere.
This book begins with his childhood and it is only at chapter 10 at page 159 that Darden talks of him getting assigned to assist Marcia in the prosecution. The book is short on details why OJ should be convicted save for some bold assertions, unsupported.
The glove evidence is frankly against the prosecution. The knife murder weapon was never found or produced in court. The lack of bruises on OJ despite the altercations is not explained.
If one is interested in the trial itself, a better book is The run of his life; The people v OJ Simpson by Jeffrey Toobin.
