Raskolnikov talks himself into the idea that some people are above the ordinary rules, kills a pawnbroker to prove he is one of them, and then cannot live with it. What I did not expect is that nobody ever argues him out of the theory. He is still half-defending it at the end. It is having done it that breaks him, not being talked round.
The other thing that stuck was Porfiry, the detective. He works out very early that it was him and then just keeps turning up and having friendly conversations, letting the pressure do the work. Reading it I kept wanting him to make an arrest and he never does.
I went in expecting something impenetrable and it is mostly people talking in small flats and on staircases. It moves.
