I'm familiar with Georges Perec's Oulipo novel "La Disparition," which didn't use the letter E, but I've never heard that Aleister Crowley claimed to have done the same. Curious where that's recorded...
"Hoper Select was already well-liked for its quality pour-over coffee, but its hole-in-the-wall, to-go-only..." (unquote)
The hyphen-to-word ration here is 1 to 3. (7 hyphens; 21 words.) That has GOT to be a record. Aleister Crowley claimed to have writter a book--in English-- without using the letter "e." Think you could do one with only hyphenated-words? "It was a dark-and-stormy mid-night. Of-a-sudden, a crashing-shot rang-out in the Carthusian-abbey..." It's harder than it looks, but you're making strides in that direction.
It might've been in his Autohagiography. It could also be he said Oulipo did it and my memory stumbled.
