This is a tremendous book. Its the basically the same trope as A Passage To India, Anglo-Indian relationships, but this just flows beautifully.
There is an immense amount of detail but the story flows along so well you don't even notice time. Its told from the point of view of several of the characters so it time shifts but all the dots are connected by the end.
This is the first of what's known as The Raj Quartet and I'm looking forwarded to reading the remaining three volumes.
Burmese Days, A Passage To India and A Jewel in The Crown all books showing fourth rate Englishmen lording it over the "natives', behaving as they imagined the landed gentry would behave.
