What I read
Finished Amnesty, and I think that was a good ending: not descending into grimdark but not fluffy-bunnies either, in keeping with the general tenor and a small note of hope.
Also finally finished The Strange Case of Harriet Hall and really, this is yet another 'neglected Golden Age detective novelist' that one can see why, really.
Catherine Dain, Dead Man's Hand (1997), which is the one where our protag has reached a place where the reader can see that perhaps the author did not quite know where to go next, which is the problem when you have a protag who changes and grows and is affected by the things that happen... I also started Dain's Angel in the Dark (A New Age Mystery #1) (1999), which failed to grab me and went into the donation bag. (Apparently there was a #2 in this series which I shall not be seeking out.)
And then I fell down an Amanda Cross rabbit hole, no, I don't know why, it just happened, they were on the shelf and I succumbed, I'm not even reading them in any particular order: Honest Doubt (2000), The Edge of Doom (2002), An Imperfect Spy (1995), The Puzzled Heart (1998), A Trap for Fools (1989), The Players Come Again (1990). And my sense is that Cross/Carolyn Heilbrun was having fun with these and being playful and not caring if they adhered to the Detective Club rules or even had a murder in them and was using that strategy of writing in genre so that she could do the late C20th version of 'o, it is only a novel' while having plots in which noxious professors get defenestrated, women bond &/or find life after unsatisfactory marriage, etc.
On the go
Amanda Cross, Poetic Justice (1970) - this must be one, I think, I bought somewhere like Sisterwrite or Compendium Books, way back in the day.
Charlotte Lennox still on the go.
Apart from more Amanda Cross, I have, I think, somewhere, a couple of collections of Heilbrun's essays.
