On Titus Oates, Bevington paraphrases BR's comments that he was a "terrible scoundrel" and "one of the really evil men of history."

On T.S. Eliot, she paraphrases BR's comments that he "forsook philosophy for the church".
On David Lloyd George, BR said, "I spent years of my life trying to hate Lloyd George, but without success. He was too lovable, much like Churchill: political scoundrels both, but you could not really dislike them."
On Winston Churchill, BR said, "The first time I saw him I was having my hair cut. The barber pointed to a pink, round-faced Harrow schoolboy in the next chair. 'Do you know who that is?' he asked me. 'That's Randolph Churchill's young cub'."
