Nevsky Prospect and the city of St. Petersburg are most frequently characterized by a high level of mystery. Most obviously there are the examples of women disappearing into alleys and later doorways, followed by intrigued men. Here mystery takes on the air of adventure, which, although sinister in consequence, at first appears fruitful and exciting. A less welcoming form of mystery is presented by Gogol in the final paragraphs of the book. In this instance, the author speaks to us directly and despairingly about the unknowable nature of those who frequent Nevsky Prospect.
