Death in the Spires by KJ Charles

I don't, like, take notes when I read the occasional murder mystery, but all the same, I'd like the record to show that on page 85, I began to wonder if it will become relevant that ( spoiler? )

and in my experience KJC is sufficiently deliberate that I feel like that's more likely than not to be A Thing.

[eta: p. 168: I think I know who did it. (I'm almost certainly wrong.)]

[eta2: In fact I couldn't have been more wrong! But I dug it the most anyway. Oddly nostalgic, though obvs my own Oxford experience involved neither undergraduates nor murders.]
