Royal biographer Robert Hardman, in an excerpt from his book "The Making of a King: King Charles III and the Modern Monarchy," disclosed that Queen Elizabeth left two letters before her demise. He described her passing as a peaceful slipping away in her sleep, with the Queen being unaware of anything at the time.
Despite these revelations, Hardman hinted at undisclosed aspects of Queen Elizabeth’s death during an interview with GB News. The author explained that he refrained from reporting certain details in his book out of sensitivity. He mentioned a particularly intriguing detail concerning the Queen's last red box, a daily fixture in her life containing papers and matters to be attended to.
As the monarch, Queen Elizabeth was known to take only two days off, her birthday and Christmas Day, with the red box delivered every other day. Hardman shared that on her final day, they opened her last red box, revealing a sealed letter addressed to then-Prince Charles and a private letter to her aide. The contents of these letters remain undisclosed, kept hidden and confidential, adding an air of mystery to the Queen's final moments and the events surrounding her death.
