Following Simpson's trial and acquittal for the murders of his ex-wife Nicole Brown Simpson and Ron Goldman, Gilbert wrote ""How I Helped O. J. Get Away with Murder: The Shocking Inside Story of Violence, Loyalty, Regret and Remorse"." The book was published by Regnery Publishing in May, 2008, and discusses Gilbert's 18-year-long relationship with Simpson, including the influence of their personal and professional relationship in the lead up to, during, and following the trial. Gilbert revealed that the gloves did not fit because, on his advice, Simpson stopped taking his arthritis medicine, which made his hands swell. Gilbert's book also details Simpson confessing to the killings. Gilbert describes how Simpson, having smoked marijuana, taken a sleeping pill, and while drinking beer, confided to him at his Brentwood home weeks after his trial what happened the night of the murders. Simpson said, "If she hadn't opened that door with a knife in her hand... she'd still be alive." This, Gilbert said, confirmed his belief that Simpson had confessed.
