I've been trying to finish Crime and Punishment for 20 years lol. Enjoy your reading!I've seen some translations of The Idiot with author name as - Fyodor Dostoyevsky, hence the doubt about the correct spelling of the Author.
Ps: Penguin Classics transliterate the spelling as Dostoyevsky
Both are correct as far as I can tell, it's just that I saw Dostoyevsky on more than one occasion.
