It is a curious fact that novelists have a way of making us believe that luncheon parties are invariably memorable for something very witty that was said, or for something very wise that was done. But they seldom spare a word for what was eaten. It is part of the novelist’s convention not to mention soup and salmon and ducklings, as if soup and salmon and ducklings were of no importance whatsoever, as if nobody ever smoked a cigar or drank a glass of wine.
