A book with long, difficult sentences

I recently tried reading "The Turn of the Screw", and constantly found myself rereading sentences multiple times just to try to understand what they meant. It was a shame, because the action seemed interesting, but I so rarely understood what was going on, as I had to parse through convoluted sentences filled with more commas than I've seen in academic reports. I'd love some recommendations that would help me come to understand this kind of writing and come to appreciate Henry James's prose.
