The Nawab and Count Bronowski had to decide whether the princely state should be assimilated into the new India or not.
We learn that Hari Kumar is now offering private tuition, having been released quietly. Merrick had got off scot-free with his maltreatment/imprisonment of Hari because the racial implications would just have made political matters worse.
Susan, Merrick's widow, was convinced he had possessed Pathan clothing to enable him to dress up and spy in the bazaars more effectively. Lots of boys had visited their bungalow, ostensibly looking for servant work.
The riot situation gets worse.
Merrick had been strangled, not killed in a riding accident and the word 'Bibighar' - the name of the garden in which Daphne Manners was raped - was scrawled on the mirror. It was suspected that he had been murdered specifically to rouse racial tensions. Clearly, his Pathan clothes were just part of his homosexual, sado-masochistic lifestyle.
The train to Ranpur/Pangkot with Sarah, Guy, Ahmed Kassim, Susan and her child was stopped and attacked by Hindus. Ahmed and all other Muslims aboard were slaughtered.
Guy goes to see Hari but fails to find him, just leaving his calling-card for him.
As Independence Day approaches the riots continue. Guy flies home, but he has kissed Sarah and asked "Will we see each other again?" She replied, "What is there to see?" and he answered, "A lot." We are being invited to assume, I suppose, that they would get together again once she returns to England.
The final shot is of the "Jewel in the Crown" picture ablaze, symbolising the destruction of India.
I hope that has gone some way to putting you out of suspense!
