Which book by "Sharbani Basu" was about the relationship between Queen Victoria of UK and her Indian servant?

A very good book. My observation on the relationship is Victoria was incredibly lonely after her husband's death and she was a voracious learner. Her Indian servant was both a companion and expanded her knowledge toward her subjects, who she barely knew.

little b, true story indeed

No need for quotation marks around a person’s name unless it’s also the name of a book or movie, etc.

maybe its interesting story about a Queen came to like his Servant

I've not read these books😥😈
