Hard Boiled Cartography

How is this for a visual aid?  Boing Boing referred to a post on Strange Maps about a publisher of pulp fiction books that printed maps of the crime scenes on the back covers of the paperbacks:  Maps of Murder.   

Dell Books, the American series of pulp fiction books, featured many genres, but most of all the detective story. A prominent feature were the maps on the back cover, setting the scene for the adventures experienced and crimes committed within the covers. An amazing 577 grand total of ‘Map Backs’ would be published during the lifespan of the series, from 1943 to 1952.

The example above is Rope, which is an excellent movie.  Aside from the interesting plot, every scene in the movie takes place in the apartment, and the movie plays out in real time.  Every minute of film is a minute in the story.  Hitchcock also shot the film in such a way that it appears to be one, long, continuous shot.  There are no cuts or jumps.  A real intense thriller, even though you know who did it from the very start.
