DARK ACADEMIA
Somehow, British universities and public schools seem to provide a particularly fertile ground for this sort of story:
* Dorothy L. Sayers: Gaudy Night (Oxford University)
* Agatha Christie: Cat Among the Pigeons (private girls' school)
* Nicholas Blake: A Question of Proof (public school)
* Edmund Crispin: The Moving Toyshop (Oxford University)
* James Hilton: Murder at School (public school)
* Michael Innes: Death at the President's Lodging (fictional college)
* P.D. James: Death in Holy Orders (priests' seminary)
* P.D. James: Shroud for a Nightingale (nursing school)
* Elizabeth George: Well-Schooled in Murder (public school)
* Elizabeth George: For the Sake of Elena (Cambridge University)
* Colin Dexter: Inspector Morse series (Oxford University)
* Susanna Gregory: Matthew Bartholomew series (Cambridge University, 14h century)
* Ian Morson: William Falconer series (Oxford University, 13th century)
* Shirley Mckay: Hue and Cry (St. Andrews University, 16th century)
DYSTOPIAN HELLSCAPE
My quartet of must-read dystopian novels has so far consisted of:
* George Orwell: 1984
* Ray Bradbury: Fahrenheit 451
* Aldous Huxley: Brave New World
* Margaret Atwood: The Handmaid's Tale
Obviously, with the impending release of Atwood's The Testaments, there might now be a fifth book to add to that group -- for the moment it's on my TBR.
INTERNATIONAL WOMAN OF MYSTERY
Based on the definition of this square, all U.S. authors are "international for UK readers and vice versa, and both of them are "international" for me. We all have plenty of favorite women writers from both of these countries -- so here are a few from elsewhere (based on MR's definition of this square as an outrcrop of "Terrifying Women"; i.e., writers whose books fit any of the Halloween Bingo categories):
* Zen Cho (Malaysia, UK)
* Donna Leon (Italy, U.S.)
* Dolores Redondo (Spain)
* Silvia Moreno-Garcia (Mexico, Canada)
* Isabel Allende (Chile; now also U.S.)
* Edwidge Danticat (Haiti)

* Karin Fossum (Norway)
