I remember a story about a guy (maybe a writer?) who is writing (on a typewriter) a warning letter to someone, about the fact that the letter “e” is now missing from our alphabet. As the story progresses, more letters disappear, making it increasingly difficult to communicate.
I thought it was a King story. It is definitely not Misery, where the typewriter is merely broken. I’ve looked throught the plots of a list of King short stories that I found earlier, and it’s not there. (I’ll find it again if anyone requests it.)
