More on the British psyche; Jane Gardam, who wrote "Old Filth" about the Raj orphans ('Filth' stands for "Failed in London Try Hongkong") and "Faith Fox", several others.
The Raj orphans were the children of British stationed in India and similar parts of the empire who at the advanced age of seven or so were sent back to England to board with more or less strangers, so they would grow up to be true British. Rudyard Kipling had a lot to say on this subject too.

Caroline Blackwood wrote several darker novels about the same world, about halfway between Molly Keane and Wuthering Heights. "Great Granny Webster" is the first one that springs to mind.

On a lighter note, a writer named Eva Rice wrote a nice book called "The Lost Art of Keeping Secrets", similar setting and characters but not nearly so dire.
