Dictionary of Literary Techniques: The Dostoevsky Dash

I'm using The Blue Bookcase's weekly question as an excuse to start writing new entries in my ongoing Dictionary of Fictional Techniques. Head over there to see what other literary devices people find interesting.

The Dostoevsky Dash:

The elision of a proper name or place with a series of dashes. 

Example:

"At the beginning of July, during an extremely hot spell, towards evening, a young man left the closet he rented from tenants in S------y Lane, walked out into the street, and slowly, as if indecisively, headed for the K-----n Bridge."

                 --The first sentence of Crime and Punishment by Fyodor Dostoevsky 

Discussion:

This one has always puzzled me. If a real place, why not name it? If a fictional one, why not give it a fake name? The best answer I have for this little convention is that it signals the line between fact and fiction. To give the name of a real place pulls the narrative toward fact, imposing restraints that the author might not want (for example, does Dostoevsky want us to be thinking of real St. Petersburg locations with such specificity? How does that change our experience of the story).

Conversely, creating fictional places pushes the story away from reality. The psychological realism of Crime and Punishment, and our visceral reaction to it, might be broken if we know that such and such a place doesn't really exist, reminding us, by proxy, that neither do these characters or actions. 

In a way, the Dostoevsky Dash is a kind of Schrodinger's Cat for fiction: it allows the novel to be both fact and fiction at the same time.
