The memoir recounts a conversation between Harry and his father, King Charles, after Prince Philip's funeral, where William employed a unique reference linked to Princess Diana's death. According to Harry, William urged him, saying, “Harold, you must listen to me! I just want you to be happy, Harold. I swear… I swear on Mummy’s life.’”
The Duke of Sussex describes the profound impact of those words, referring to them as a "universal password" and a "soul-crushing vow" reserved for times of dire need since their childhood. The incident occurred as the father and sons were walking through Frogmore Gardens hours after Prince Philip's funeral.
However, despite the use of the sacred phrase, Harry reveals that the attempt to bridge the emotional gap "didn’t work." The brothers were in a place of deep hurt and doubt, and the powerful words couldn't mend their strained relationship.
"Spare" not only explores these intimate family moments but also revisits Prince Harry's early years in the British Army and his romance with Meghan. The memoir quickly became a bestseller and was named Amazon's "Most Sold" book of 2023.
