Sonia's depiction is so expressive; Dostoyevsky was genius in balancing the unspoken and the outspoken that the amplification left to readers was flexible yet with clues.
The tiny motions were captured perfectly, terse and accurate, I can't help comparing his tone to Fitzgerald's, which was cooler and brifer, but powerful enough as well. Every scene is particularly detailed however necessary, you won't find prolicity in any sentence. The main body is conversations, while the author cut in other description timely about characters' psychology, facial expressions and movements.
If I was the playwright or actor, I'd be grateful to Dostoyevsky who had swept all the difficulties away for me to adapt or play.
