Nanny Janet Thompson tells of peeking into the Sandringham drawing room and seeing the Queen in a game of hide-and-seek with six-year-old Andrew and a cheery five-year-old Diana. In her account, Prince Charles, then seventeen, walked in at teatime and asked, “Everything all right? It looks like a good party to me”—a cameo appearance that seems rather poignant now, conjuring up as it does the young heir to the throne’s large well-meaning ears, his fogeyish big brother concern, and his tiny future wife giggling behind a heavy silk curtain.
