Back on the topic of atmospheric Halloween stories, within the Kirby JIMMY OLSEN run, the story in 142-143 definitely fills the bill.
But on top of that, this cover for 142 offers one of my favorite Adams/Kirby collaborations :

Kirby drew this cover for issue 142, but DC didn't like the angle Kirby had Superman posed in the pencil version, so they gave it to Neal Adams to re-draw the Superman figure, which Adams did pencils and inks for, and then the other figures and background were inked by Mike Royer. So it gives a fantastic side-by-side of Adams' and Kirby's styles, in the same cover image.

Here are the original cover pencils before Adams erased and re-drew the Superman figure. It looks in this image like Royer inked these xeroxed pencils (including the original Superman figure by Kirby) sometime after the fact, for a commission.

And here's the unfinished pencils it was inked from :
