Thanks for mentioning Henry Green, he wrote nine novels, but earned his living working in the family firm H Pontifex & Sons, starting on the factory floor and becoming managing director eventually. He manages to empathise with the workers to a remarkable degree, for an Eton and Oxford aristocrat. His novels are experimental, not least in their prose style. I'd recommend him for anyone who enjoys Virginia Woolf and who is not put off by modernist fiction with a wider social range. He worked in the Auxiliary Fire Service in the war.
Party Going is a favourite.
