Besides the sketches, she has written extensively about Indian rulers at the time (e.g. Ranjit Singh). If you found this interesting, you would love the Empire Podcast... I believe they talk about Emily in the episode on Afghanistan (https://podcasts.apple.com/gb/podcast/79-invading-afghanista...); Dalrymple's book on the subject (Return of a King, https://en.wikipedia.org/wiki/Return_of_a_King) is also a masterfully well researched, delightful read.

+1 to Empire Podcast. They have excellent series on a bunch of empires (well researched with references). Its one of those light, informative, non-boring podcasts: - The British Empire & The Raj - The Ottoman Empire - The Russian Empire - The United States as an Empire etc

William Dalrymple's books are great reads. Makes reading history enjoyable. Highly recommend all his books, particularly his most recent 'The Golden Road'
