>I’m studying classics at university and during a modern literature module we studied Jane Eyre. Now I have read it all, written many notes and essays on it and have a pretty good grip on it (not particularly hard when the author is the least subtle author I have ever read).

Right. You've written 'many essays'. 'Least subtle'.

I don't know where to begin here, but the fact that you don't understand vol 3 belies the 'least subtle' notion. Never mind what it says about the 'many essays'.
