We get stuck with how people see us
Remember that children's picture book with the sea-ghosts I was mentioning a few weeks ago? I found it. It's Birdy and the Ghosties (1989); I recognized the cover illustration immediately. What I didn't remember was its author, Jill Paton Walsh. Who is also responsible for The Green Book (1981), which
rushthatspeaks and I both read in elementary school, possibly under its reissue title of Shine, and A Parcel of Patterns (1984), which traumatized us a few years later. Who knew? At this point, I'm just waiting to see what else turns up out of her bibliography—oh, wait, Fireweed's (1970) hers, too. Yes, I have been recommended Knowledge of Angels (1994). What I can't figure out is how she seems to have wound up best known for her Sayers fic.

It's how I discovered her as an adult; she seems to write mysteries lately, both Wimsey and a series of her own. You may be right that it's an angle-of-approach thing.
But she's one of those very versatile writers who probably have different identities in different people's heads, depending how they first happened to come across her.
Assuming they remember . . .
Do read Goldengrove and Unleaving (sometimes published in a single volume) if you get the chance.
I approve of the titles!
