Cynthia had been on friendly terms...

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 preverse 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 throgh, 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. -- "The Vane Sisters" (1951), Vladimir Nabokov
