Cheers aristo, I probably wouldn't have noticed the title last week! and yes "probably" is an example of litotes.
I haven't started it yet as I've been asked by a mate to help his son with his choice of book for English at school. It could have been worse, Scott's "Waverley" which I last read 20+ years ago. Not sure I want to read it as a crit though.
From the snippet you've provided (not that I had any doubts beforehand) I know I will enjoy it. I also noticed the free flowing and inherent deadpan style when I was browsing pre-purchase.
