One of the things that Daniel Petrocelli, the prosecutor in the civil case against OJ realised was that the more OJ speaks the more he condemns himself. OJ's narrative account of his marriage to Nicole is fascinating, because it gives - against his intentions, presumably - a clear insight into his personality. Nicole, according to OJ, was an 'accident waiting to happen'.
The murder confession chapter is also enlightening to anyone still interested in this case. (Guilty, your honour!) OJ invents a kind of blackout at the point of killing Ron and Nicole, but even allowing for that, if one disregards the unsubtle lies and self-justifications of the account, bits of likely truth are clearly there in OJs description and attitude. 'Charlie' helped him kill them. That I don't doubt. Lethal stuff, especially if taken by a violent psychotic.
Worth buying, particularly as the money doesn't go to the murderer.
