The best way of doing that is to click on "more searches" in the top-right corner of your screen, and search for "waugh" in lists and comments. If no lists show up with "waugh" in the title or description, then you might find such a list by looking at comments with "waugh" in them, and tracing through to the attendant list.
But I've just looked and there don't seem to be any Waugh-specific lists as yet - so go ahead and change that!
You do know that he wrote at least two endings -- the edition I have just returned to the library had a bleak one and a less bleak one. Both bitingly funny. (Although I like the cannabalistic end to the aviatrix in his Ethiopian-inspired novel.)
