|London Book Fair, Earl's Court. Mice in a maze.|
|Has Africa learned it all then?|
Go up on the balcony and watch the fairgoers dither like laboratory mice as they wander up and down the alleyways, searching for a direction; laugh at the Japanese lady who tows a low suitcase through the crowd and fells half a dozen people who do not look down before they move; giggle at the office juniors, out for the day, trying not to fall off their high heels as they negotiate right-angled corners.
But don't go there to do any useful work.
