Few, if any, tidbits of the content of the Duke of Sussex’s long-awaited memoir have so far emerged. “It’s juicy, that’s for sure,” a source told US website Page Six, with another adding: “There’s some content in there that should make his family nervous.” From the prince, the palace, the publishers Penguin Random House and the Pulitzer Prize-winning ghostwriter, JR Moehringer, there was silence. However, royal watchers expect it to be a serious book, not to be dismissed easily. Novelist and journalist Moehringer, who wrote the autobiography of former world No. 1 Andre Agassi, “is a powerful and psychologically probing writer, so we can expect a powerful and psychologically probing book,” said historian and royal biographer Robert Lacey . Agassi’s book “is deep, serious, a forensic demolition of his upbringing that goes beyond the normal ghost-written books,” Lacey added. “It makes me think there’s no point in even guessing what skeletons he’s going to uncover because he’s a skeleton exhumer. He’ll do the business.” A publishing source told the Sun: “The manuscript is complete and has gone through all the legal processes. It was also done by Harry’s hands. The publication date has been pushed back once, but it’s on track for the end of the year.” Harry only said when he announced his literary memoir last year that it would be “the highs and the lows, the mistakes, the lessons learned … a first-hand account of my life that is accurate and absolutely true.” But there are hints of what might come in Oprah Winfrey and other interviews she’s given. He told Dax Shepard on the Armchair Expert podcast, for example, about the “genetic pain” of being brought up in the House of Windsor and that Prince Charles treated him “as he was treated”. Lacey wonders if Moehringer’s pen can be traced to those words. “One would expect a book that sets new standards in royal analysis. hope [Moehringer ] will also analyze the institution. In Agassi, not only did he tear down Agassi’s parenting and upbringing, but he hit the professional tennis world hard. So you would expect the same kind of double-edged attack in what he writes about Harry and the monarchy,” Lacey said. “He doesn’t write books that can easily be dismissed as scandalous, they have substance.” Moehringer’s heated interviews with Harry will likely have mostly taken place before the Sussexes publicly reconciled with the royal family for the platinum jubilee, “almost in a fit of rage, with the funds locked up some time ago,” he said. Lacey. “So Harry himself may regret what he finds out he said – given that the Sussexes seem to have denied their animosity towards the family.” No member of the royal family appears to have seen the manuscript. However, it can be assumed that anything deemed defamatory – especially in light of accusations of racism leveled by the couple – will undergo a strict legal process before publication. Royal watchers expect it to cover controversial areas of his upbringing, his mother’s death, his allegedly less-than-easy relationship with the Duchess of Cornwall and Harry and Meghan’s emotionally charged exit from the royal family with all its tensions with the palace guard in time. The couple’s version of the bullying allegations against Meghan may also be affected. “But we can also expect total respect and deference to the Queen, that will prove his loyalty to his grandmother and the monarchy, and that will be his line of defense, I imagine, and then everyone else on the battlefield is a legitimate target.” , Lacey said. He hopes it will shed light on the Queen’s role as William and Harry’s foster mother after Diana’s death. “I would also be fascinated by what Harry thinks he got from his uncle and aunts – [Diana’s siblings ]– at this difficult time,” Lacey said. If publication is on track for the fall, Harry would be up against Michelle Obama’s new autobiography. Subscribe to First Edition, our free daily newsletter – every morning at 7am. BST Harry said he is writing the book: “not as the prince I was born, but as the man I became.” Buckingham Palace is unlikely to comment in detail on any allegations contained therein unless absolutely necessary. An indication of how she might handle any fallout can be found in the Queen’s famous statement after the couple’s interview with Oprah, in which she said: “Memories may differ.”
