"The Run of His Life: The People v. O. J. Simpson" by Jeffrey Toobin is a good one to look into. I enjoyed it thoroughly, and found Toobin to be a great and engaging writer. It also was the basis for the 2016 FX dramatization "The People v. O. J. Simpson: American Crime Story", which I guess is neither here nor there, but does point to its stature. In any case though, Toobin one of those covering the trial when it happened, and turned it into a book after, and it definitely is one of the best regarded works to come out of it, and has weathered the past two decades to remain at the top. I'd point to this re-review by the Guardian for a good take on it.
