Buckingham Palace confirmed on Monday that King Charles III, Britain’s monarch, is being treated for cancer. Prince Harry — estranged from his family — flew from Los Angeles to London on Tuesday for a visit with his father that lasted around 45 minutes.

In his dreadful memoir, Spare, which I reviewed for the magazine, Prince Harry detailed that in 2021 his father begged him and his brother, “Please, boys — don’t make my final years a misery.”

Now is the time for Harry to take that request seriously, starting with a full apology.
