>Tolkien’s unpublished letter to John Bush, 12 March 1966. Tolkien writes ‘Thank you for sending me a copy of Dune. I received one last year from Lanier and so already know something about the book. It is impossible for an author still writing to be fair to another author working along the same lines. At least I find it so. In fact I dislike DUNE with some intensity, and in that unfortunate case it is much the best and fairest to another author to keep silent and refuse to comment. Would you like me to return the book as I already have one, or to hand it on?’”.
