In "White Nights", one of Dostoevsky's masterpieces, the narrator meets Nastenka, the young girl with whom he falls in love, during a night walk.
My question is: from an historical point of view, is it imaginable that a young woman could walk alone during the night in Saint Petersburg in the first half of the nineteenth century (even if, given the geographical position, the night was not dark)? Were the women of that period free to walk alone during the night?
I would appreciate, in particular, any references which describe the social conditions for women in that period in Russia.
