And so I came at last to the muddled headwaters of the Disputed Narrator Metanovel*. 
 Yes, it was good (with "good" serving as vast understatement of "visionary"). No, I haven't worked through the half of it. I'd be glad to debate about this book with anyone, though. 
 *Later Note: Okay, so Giles Goat-Boy beat this to the punch, maybe, but Barth handled it so badly and boringly that I'm still gonna say that Nabakov defined the tradition.

 Things to seek further (notes to myself, basically): 
 1. Hazel word-flips in the text. "Didactic Katydid" is a weird sort of semi-palindrome, similarly Kinbote / Botkin flips the syllables. Is there an implied connection here besides the obvious Botkin identity issues? Do more of these word flips occur? They must be there for a reason. 
 2. From the first page: "Canto Two, your favorite". I haven't really seen this discussed elsewhere, but who does Kinbote think he is addressing? 
 3. Where are the "Crown Jewels" and does it matter? It's irrelevant as far as plot points go, but again, surely they are incessantly referenced for a reason.
