I know nothing of Turganev, honestly. I have read The Idiot and felt it was a little “less” than usual Dostoyevski, but I can highly recommend White Nights, a collection of short stories. I usually think of Dostoyevski as shining in long descriptions, but in White Nights he goes the other way and etches scenes with a minimal amount of details and still hitting the nail on the head. Notes from the Underground doesn’t have a good translation in my mother tongue, so I did not read it yet. Now that my English knowledge is good enough, I could look for a good English translation, but there are just too many books to read… what to read next is always a tough choice.
