Across the partition is the plane’s first class. Three of its four seats are occupied by Australian fat-cat businessmen. In the fourth is an Indian woman in a sari. She’s getting all the attention from the staff. Who could she be? I try to get a clue from her reading: The Economist, Business Week and Milton Friedman. She seems to have an entourage too: a man and a woman, both in business class. Who could she be? I decide not to probe further: sometimes in life it’s better to leave some mysteries hanging in the air.
