Believe it or not, I've almost finished!
Rather strange, but very good. I can't outright recommend the series for general consumption due to length (over 1,900 pp.!).
That was televised in a classic series back in the 80s by the Beeb.
I know of the series, but never saw any episodes. Now, having read the whole quartet, I'm amazed it was TV-serialized! Doesn't seem like very telegenic material, and I don't know how they managed to cut it down to a manageable size. Maybe I should check out a DVD or two.
