AS dusk sets, a strange silence takes over Punya, the private residence of Karnataka chief minister J.H. Patel. Ensconced alone in his first-floor room, 67-year-old Patel watches a slapstick comedy Kannada teleserial on Bangalore DD. On another day it could be Discovery Channel. Or he could be listening to Kumar Gandharva. Missing from the scene are the regular hangers-on: some ministerial colleagues and friends. And most conspicuous by their absence are the tinkling of glasses and the free-flow of imported scotch whisky.
