A new book reveals the real reason why the Princess of Wales did not join her husband Prince William at Balmoral shortly after Queen Elizabeth's death on September 8, 2022.

In his new biography, The Making of a King: The Making of a King, author Robert Hardman refutes the theory that Kate was asked to remain in Windsor; rather, that day coincided with the first day Prince George, Princess Charlotte, and Prince Louis started school together at Lambrook Therefore, he claims that Kate chose to remain.

According to the book, Kate believed that one parent should be with the children on such an important day, and William obviously needed to be with his grandmother (although he did not make it to her bedside before she died) and his father, the new King Charles.

In 2022, Meghan Markle was reportedly asked to remain behind while Prince Harry headed to Scotland, and "People" reported that Kate was believed to have been excluded for the same reason. However, according to Hardman, it was Kate herself who made this decision. It was more by luck than judgment, but it made it a lot easier to tell Harry that she was coming alone," one royal aide said in The Making of a King.

In his memoir Spare, Harry recounts Prince Charles asking Princess Meghan to stay: "Prince Charles said I was welcome to stay at Balmoral, but he didn't want Princess Meghan," Harry wrote." He began to lay out his reasons, but they were nonsensical and disrespectful. Don't talk about my wife that way. He clammed up and said, apologetically, that he simply didn't want a lot of people to come. My other wives don't come, and Kate doesn't come. Then I should have just said so."

Harry chartered his own plane, and the news of the Queen's death became public during the flight. In Hardman's book, a palace staff member said that Prince Charles had tried to contact Harry urgently but was unable to reach him. 'Charles had been trying to get in touch with Harry urgently, but was unable to.'

The book also reveals that fortunately the queen breathed her last "very peacefully . . in her sleep. She breathed her last quietly. Sir Edward Young, the Queen's private secretary, who was at Balmoral when the Queen died, wrote in an unpublished note: "She would not have noticed anything. She would have been unaware of anything. There was no pain."

The Making of a King is available now.
