help out a secret history die-hard fan

i am in love with the secret history, and have been for some time. I’ve read the goldfinch, too. I’ve also read If We Were Villains (Kuang), Talented Mr. Ripley (Highsmith), Bunny (Awad), Rabbits (Rifkind), The Group (Eklund), and a more recent publication (or I suppose it’s more fair to say recent translation) called Summerhouse (Karaahmet). I was also a (please reserve judgements) fan of the Saltburn film, mainly for its creepiness but not necessarily graphic “horror”.

Long story short, I like a story that involves very intelligent academic people becoming crazy and following a psychological thriller plot. Any book recommendations are much appreciated as I feel I have read every book of this kind :,)

thank you!!
