Nabokovilia in David Mitchell's Cloud Atlas

From David Mitchell's remarkable Cloud Atlas:

Speak, Memory. No, not a word. My neck moves. Hallelujah. Timothy Langland Cavendish can command his neck and his name has come home. November 7. I recall a yesterday and see a tomorrow. Time, no arrow, no boomerang, but a concertina. Bedsores. How many days have I lain here? Pass. How old is Tim Cavendish? Fifty? Seventy? A hundred? How can you forget your age? (354)
