A few years ago, Brian Wedemeyer, an elementary school principal in rural Arizona, is watching a documentary about the murders of Nicole Brown Simpson and Ronald Goldman when a question suddenly pops into his head. He expects to get a quick answer on his cell phone, but it is nowhere to be found.

A former journalist, Wedemeyer does not give up. However, as he painstakingly searches through court transcripts from both criminal and civil trials, he uncovers some unbelievable stories on the other side of O.J.'s MOON. These stories are unknown to most followers of the biggest murder case in America's history because public attention is often fixated on the bright side of the moon—whether or not O.J. did it—You know, the usual ... gloves, DNA, 911 calls and Mark Fuhrman. However, as Wedemeyer will soon learn, there is plenty more to talk about on the flip side of the "Mezzaluna," which stands for crescent moon in Italian. Wedemeyer is the only person outside of law enforcement to interview Tom Lang, Nicole's neighbor from down the street.

Prior to his death in 2021, legendary attorney F. Lee Bailey describes Lang as the "most compelling witness" of the O.J. Simpson murder trial—but, for some reason, never takes the stand. Lang is a very credible witness who was standing on the corner of Bundy Drive and Dorothy Street just minutes before the murders take place. In this book, Lang reveals, first-hand, exactly what he saw that night, and what does happen afterward. Wedemeyer also goes beyond one of many conspiracy theories to figure out exactly what happened to Michael Nigg, a former Mezzaluna waiter who knew Goldman and even hooked him up with a job at the restaurant.

Nigg, who left Mezzaluna for a job at a popular Beverly Hills nightclub, is shot to death by thieves on Sept. 8, 1995 while on a date with his girlfriend. Michael's case receives very little media attention over the years and remains unsolved to this day.
