Years in insurance and marriage to the joyless Hilda have been no more than death in life to George Bowling. This and fear of another war take his mind back to the peace of his childhood in a small country town. But his return journey to Lower Binfield brings complete disillusionment.
I agree Down and Out in Paris and London follows close behind, and the best of his essays come next.
I think Homage to Catalonia is not a great book, but valuable for the autobiographical insight about Orwell, and how it informed him to write those other, better works.
I would also add that Coming Up For Air is delightful and underrated. Try the audio book. Any middle-aged man can appreciate the quiet understated honesty.
The book shop that Orwell worked in and lived above when he wrote Keep The Aspidistra Flying is now split between a fancy bakery and a hairdresser. I get my hair cut at the hairdresser.
