“A generation ago,” Nesbit was saying, “a man in my position might argue that the British would remain a part of India always; now, only the most self-deluding burra-sahib would claim that. This country is set on the road to independence, a journey we have the responsibility of assisting and guiding. And as we prepare to step aside, two competitors are jostling to move into the vacuum of power: the Congress Party, which is largely Hindu, and the Moslem League. I’m sure you are fully aware of the deep and abiding mistrust and simmering violence that exists between Hindu and Moslem here. The two religions are essentially incompatible: Moslem views Hindu as a worshipper of idols, Hindu condemns Moslem as unclean cow-killer. And that isn’t even beginning to touch the other parties, the Communists on the one side and the swarajists on the other, who hate and mistrust each other.

I mean to say, we’re happy to allow a proved friend of the Crown a certain amount of leeway when it comes to governing the country his family have ruled for centuries, but one can only turn a blind eye on depravity and despoilment for so long, and buying small children for . . .” Nesbit stopped to study his hands pinkly for a moment. “For purposes best suited to the harem, goes too far. In any event, his age caught him up before the government could step in, and he died in his bed at the age of eighty-four, his only son long dead and his eldest grandson Jimmy just eleven.
