Hello John,
You're quite right — I went up the Normal/Easy Route, first with my father, Tim, then with the Swiss Guide Jean-Noël Bovier.
Tim climbed the Ferpècle Ridge in 1982.
Neither of us have been up the North Arête/Face since it's terrifying and leagues beyond us — as it's beyond most but he very best climbers, I'm sure. A quite amazing feat to have been achieved in 1928.
Very glad you enjoyed the book!
Best Wishes,
Dan
