When the Forsyte Saga was on the Swedish television in the sixties, I was young and mostly interested in the historic aspect and the clothing and the intricate love stories.
I read it recently (in Swedish translation), and realized - now in my mature age - that Galsworthy has written a most modern critique of society. The victorian society, of course (which in people's minds lasted into The World War II, despite new technology), but so many aspects apply to our times. The author has a profound understanding of the human nature, and what made the victorians tick. All of us.
