That is a good point, I wonder if Christopher is in possesion of his fathers diaries, if any existed, I am sure they are mentioned somewhere, it would have been normal for one of his generation and position to keep some form of diary. I wonder if that is what Tolkien alludes to in the matter of destroying anything. Was there not mention of a second Letters book?, there must have been thousands, I have often wondered to what extent Christopher purged that book of any dubious statement by his father, in much the same way that holy men did at The Council of Nicea, when deciding which books would fit the Judeo/Christian Myth best, therefore omitting the Book of Enoch and such like.
