The tool was there, it must now be put to use. My first duty after Sebastian's death was to go through his belongings. He had left everything to me and I had a letter from him instructing me to bum certain of his papers. It was so obscurely worded that at first I thought it might refer to rough drafts or discarded manuscripts, but I soon found out that, except for a few odd pages dispersed among other papers, he himself had destroyed them long ago, for he belonged to that rare type of writer who knows that nothing ought to remain except the perfect achievement: the printed book; that its actual existence is inconsistent with that of its spectre, the uncouth manuscript flaunting its imperfections like a revengeful ghost carrying its own head under its arm; and that for this reason the litter of the workshop, no matter its sentimental or commercial value, must never subsist. Curiously, though, there is something twisted in its logic that makes me doubt V.'s conclusions. It might be his affirmation that the "printed book is the perfect achievement" or, more to the point: that its actual existence in print is in stark contrast to its spectre (the imperfect manuscript).
The burning theme crops up often enough ( the story of Lolita's manuscript saved from the fire; John Shade's backyard "autos-de-fé" and Kinbote's appropriation of his manuscript and discards). Besides we find fictional commentators writing notes to fictional editors which, together with other "uncouth" corrections are printed to become an integral part of the book. We also have VN's own shoe-boxes loaded with index-cards which an interviewer is invited to examine and allowed to reproduce, in part.
What "abime" stares at us and what lies "inside/outside" a "finished" book?
In TRLSK we find a curious situation: V. constantly aludes to a book he is writing about his brother, but the reader doesn't have a chance to see it at all: all he is offered, in print, is a kind of diary standing for V's "perfect achievement". For example (ND, page 23) in chapter Two: 'Write that book, that beautiful book,' she cried as I was leaving, 'make it a fairy-tale with Sebastian for prince. The enchanted prince [...]We parted. It was raining hard and I felt ashamed and cross at having interrupted my second chapter to make this useless pilgrimage".
