Ok The Hearts Invisible Furies and In Cold Blood are both good. Cold blood is about an actual murder but it’s written by Truman capote, a gay man and he focuses primarily on Perry Smith who is portrayed/very likely attracted to me including his partner in crime, Dick Hitchcock. It is widely hypothesized and hinted at that Perry and Truman capote were in a relationship as well. It’s very good, interesting in general cause murder and you can read into it a lot in regards to Perry. I have both these books and could lend them to you
