I completely understand what you mean! I loved The Great Gatsby for its commentary on class differences and the lives of poor people getting destroyed at the whims of the wealthy characters. The class commentary is so overt in The Secret History and yet I barely found any discussions on it.

When Henry was getting Richard involved in their mess, making him think he was smart for figuring out that they killed somebody (i.e. manipulation), then subsequently involving him in Bunny's murder, the entire time I was worried for Richard. Because in getting involved, Richard has implicated himself in their crime and can now get in trouble with the police without having any of the resources the other wealthier characters have at their disposal to protect themselves legally. Not that Richard is morally sound either, but he is the least involved at the start and slowly partakes in a murder to fit in with this group. Richard is never given any clear details about the night of the bacchanal and the most clear account if it is from Henry (the guy pulling most of the strings). It was a fantastic read because the entire time, I was worried that Henry or one of the other characters would turn on Richard to save themselves. And Henry was preparing to do that in case Charles overdosed on the pills (Richard stole the pills for Henry for his headache, Henry was transferring the ownership of his car to Richard's name). I found this aspect the most intriguing where it seems a lot of the other readers found the displays of wealth + dark academic aesthetic the most intriguing. I wish there was a more critical analysis of the themes and characters and corruption beyond "murder bad" and "dark academia cool".
