"The Forsyte Saga" by John Galsworthy (1867-1933). I'm probably going back a bit further than you had intended, but I don't see how this thing won a Nobel Prize. - I shouldn't say that: It probably won a Nobel Prize because it was the world's first soap opera: He marries Her, but She sleeps with Him, and one woman steals another woman's man, but somehow we all manage to get over it and have no hard feelings by the end. Sorry but, Nobel Prize or not, I need something with a little more depth.
I should also note that I do not use awards and prizes to gauge what I read. But if something is given a world-class award, I think it should be just that: world-class.
