I said in my introduction how I was a voracious reader, but fell out of the habit, but have been getting myself back into it - both as a result of the recent (and for me, current) Lockdowns, and because of pressure from my partner! Very welcome pressure, I hasten to add. I've even set up a YouTube channel where I do readings to get me motivated. The most recent story I read for it is an M. R. James one - "A School Story". When I was younger, I loved M. R. James, and returning to him I'm glad to find that I still do!
With horror stories based on atmosphere rather than shock or gore, I think he is one of those writers where "master of the genre" actually means something. He is able to create calm, relaxed atmospheres - often of academia, where he worked - whilst building up, somehow, a disturbing background, so that when the supernatural actually intrudes upon this world, it is - at least to me - more effective than many other more "obvious" writers in the genre. A short story, and I've been reading a fair few horror stories for a Halloween playlist, but I don't seem to tire of M. R. James!
(This is my reading of it - [link removed] - not sure now links outside to such things are regarded here, I'll take it down if it shouldn't be here!)
