In a 35-year unpublished longitudinal study, I have confirmed her theory.

Add Bulgaria too. I liked Illusions but a good friend of mine was simply in love with it, bought and gave copies to everyone. And for his birthday last year I almost gave him a signed copy of the Seagull I saw at a local second hand bookshop in LA. I hesitated because of the price and when I came back it was gone.
