The Jewel in the Crown S01E10 - An Evening at the Maharanee's

Sarah travels to Bombay to meet her father, Colonel John Layton, who has been freed from his prisoner of war camp. Colonel Layton is concerned as to the well-being of a Havildar from his Regiment who apparently joined the Frei Hind, the Nazi version of the Indian National Army who fought with the Japanese. The officer in charge of the case is Major Ronald Merrick and he takes sadistic delight in belittling and degrading the Havildar during interviews.
