Regency books with "theatre" scenes
I'm working on my own story and have been stuck on my planned "night out at the theatre" scene for *weeks*, so I'm trying to reread some old theatre scenes to get my brain on the right track. A lot of books will mention "going to theatre" or "seeing [blank] at the theatre" but not a lot actually flesh out the theatre scene. I can vaguely recall old scenes that I've read, but can't specifically remember most of the books they come from so I'm unfortunately adrift within my own library.
Are there any books you recall specifically having a well-developed theatre scene?
