Anyway, apparently McPhee is still with us.
Oh, I knew he was still alive, as is Trillin. What I meant was, weren't they both among the
New Yorker's most prominent contributors some years ago and now still write occasionally but not very often?
And apparently that is the case, although according to his list of bylines on the site, McPhee has published something there every six months to a year, including as recently as April. Trillin's contributions have dwindled from a few a year in the late teens to about once every year or two now. Both are described as staff writers.
And that author whose name I can't remember? I still haven't remembered it. It's one of those things that usually come to me when I'm not thinking about it.
I think her first name is Margaret, but maybe I'm imaging her--like the McPhee article. 
Lee is probably correct; you must be thinking of Margaret Talbot. I've always liked her, although now I can't remember why. I must have really liked something she wrote a long time ago.

Anyway, looks like she contributes something every few months.
About eight years ago, Talbot wrote something about the singer Kate Bush, which interested me because I'm not very familiar with Kate Bush and only recently discovered her song
Wuthering Heights. WH was one of my favorite books in childhood -- I read it about 12 times, or about the same as
Gone With the Wind and
The Godfather (kind of an odd mixture, I know). Anyway, her song is weird and kind of spooky, better capturing the book's spirit, so to speak (she imagines scenes involving Cathy after her death), than the overromanticized film adaptations, including the recent one with Margot Robbie and Jacob Elordi (which I haven't seen but can tell from the trailer is not very true to the book). I did a quick scan of Talbot's article and see that she mentions the song and video, so I'll read the article later.
