The apartment where Dashiell Hammett wrote "The Maltese Falcon" was once in the boundaries of the Tenderloin at the corner of Hyde and Post. Both the movie and book were based in San Francisco's Tenderloin. There is also an alley in what is now Nob Hill, named for the book's author (Dashiell Hammett). It lies outside the Tenderloin because the boundary was defined with borders different from today's. Some locations, such as Sam Spade's apartment and John's Grill, also no longer lie in the Tenderloin because local economics and real estate have changed the character and labeling of areas over time.
