He also wrote tons of T.V. and movie critiques; all of which I have have also read. He has a very mordant wit, which I find quite funny.
Hitchcock used quite a few of Dahl's short stories for his show; my favorite one is, IIRC, called :"THE LEG OF LAMB". I don't know if they are still in print, but his stories, in this vein, used to be available in paperback collections; which is what I bought in the late '50s.
I'm not certain just when I bought the Bierce anthology, but I think that it must have been about the same time that you bought it. THE DEVIL'S DICTIONARY was just an excerpt, so I bought the entire book and another one too, at the same time.
Have you ever read any of Jack Finney's books/short stories/novellas? You might enjoy him. His best known is probably INVASION OF THE BODY SNATCHERS, due to all of the movies made from that book. But his other work is also VERY good; though his much awaited sequel to TIME AND AGAIN ( my favorite of his books ) was NOT up to snuff; sadly.
I don’t know Finney, I’ll have to investigate. I see than Audible has some Ellison that I can try. The Dahl that they have are his kid’s books.
