People​ who write unauthorized biographies often get authorized rebuttals. In 2004, when Kitty Kelley published The Family: The Real Story of the Bush Dynasty, the disaster-prone House majority leader Tom DeLay wrote to her publisher, Doubleday, that she was in an ‘advanced stage of her pathological career’. He also claimed that Doubleday was in a state of ‘moral collapse’. Kelley was opposed to authorized books, believing that the art of biography should never be a branch of the public relations industry, and neither should journalism. ‘Approval’ was irrelevant. It could be said that Kelley often took a little too much pleasure in the delinquencies she spotted. She once stole a badge from Christopher Hitchens that said ‘All the Right Enemies’.

Choosing whom to hate is an exact science for the enterprising biographer. With an excessive and portable moral hauteur, the intrepid muckraker tends to find subjects whose awfulness plays well with the awfulness of the period, setting the scene for a well-timed explosion of gossip and dirt. David Beckham, who once had a golden right foot, a sweet face, a high voice and a famous willingness to sit around in branded underpants while being photographed by the world’s press, might have proved a sensational subject all by himself, a walking-and-squeaking reality TV show.
