Prince William looks good in uniform and Man-at-Hackett black and white tie (he has grown up wearing it constantly); less certain in his suits, which sometimes look borderline archaic; and variable in casual. But completely comfortable in the Sloane uniform of non-designer jeans and chocolate-brown suede loafers. He'll look fine in Boden.

When you get inside a literary novel you feel that the author, more often than not, just doesn't know enough about things. They haven't been around enough - novelists never go anywhere. Once I discovered true books about real things - books like 'How To Run a Company' - I stopped reading novels.

There was a time when formal clothes were one of life's great pleasures, as well as a way of describing instantly a man's status wealth. Toffs wore the most, the proles the least.

Nobody knows anything. I deal with people in all walks of life, some of whom should have some idea of what they're doing. And they're all clueless. It's astonishing that any bridges stay up, or that planes don't constantly plummet from the sky. It's heartening, in a strange way.

Something rather plain but satisfactory about the interior. And that lovely enamel wotsit in the middle of the steering wheel. A moment of quiet 'because I'm worth it' pride.

Brands are useful ways of short-handing practically anything - look at the way Tom Wolfe first used brand name lists to sharpen up a character and a situation. Look at the most brand-referenced novel, Bret Easton Ellis's 'Glamorama.

I can remember when anything further downtown New York than Canal Street was risky and the whole area still looked like a 70s cop movie location; when the original loft-owners were more dash-than-cash, artistic types.
