I've had great sympathy for Laurence Llewelyn-Bowen for a while and was greatly surprised and amused with his (and his wife's) book: A Pinch of Posh. I confess I was expecting a "very serious" book on good manners but as it turns out this a well written, witty book, that will make a great Christmas gift... for the Posh Ones and well... for the not so Posh.
