When I tried to find out about the "Epiloque" I was referred to the first few chapters of the book, when NN was living in exile and reminiscing. It's a shame that we've all been discussing things "at sixes and sevens" as my mother would say!My book ended the same as yours. All the talk of an epilogue with additional info is just confusing to me, since I haven't seen / read it.
But it's reassuring to know that at least we both read the same book!
