Read & listen: Nabokov's "The Vane Sisters" & Girl in a Coma's "Sybil Vane Was Ill"

Nabokov's second to last short story, published in 1951. Features a device Nabokov said could "only be tried once in a thousand years of fiction." A fantastically unreliable narrator, word games, seances, planchettes, wacky women, and a paragraph to pay attention to:

     Speaking  of  old men, one should add that sometimes these
posthumous auspices and interventions were  in  the  nature  of
parody.  Cynthia  had  been on friendly terms with an eccentric
librarian called Porlock who in the last  years  of  his  dusty
life  had  been  engaged  in examining old books for miraculous
misprints such as the substitution of l for the second h
in the word "hither." Contrary to Cynthia, he cared nothing for
the thrill of obscure predictions; all he sought was the  freak
itself, the chance that mimics choice, the flaw that looks like
a  flower;  and  Cynthia,  a  much  more  perverse  amateur  of
misshapen or illicitly connected words, puns,  logogriphs,  and
so  on, had helped the poor crank to pursue a quest that in the
light of the example  she  cited  struck  me  as  statistically
insane.  Anyway, she said, on the third day after his death she
was reading a magazine and had just  come  across  a  quotation
from  an  imperishable  poem  (that  she,  with  other gullible
readers, believed to have been really composed in a dream) when
it dawned upon her that "Alph"' was a prophetic sequence of the
initial letters of Anna Livia Plurabelle (another sacred  river
running  through,  or  rather  around, yet another fake dream),
while the additional h  modestly  stood,  as  a  private
signpost,  for the word that had so hypnotized Mr. Porlock. And
I wish I could recollect that novel or  short  story  (by  some
contemporary  writer,  I  believe)  in  which,  unknown  to its
author, the first letters of the words in  its  last  paragraph
formed,  as  deciphered  by  Cynthia,  a  message from his dead
mother.
