Place has always been an intrinsic element in the detective story from the Paris of Poe’s Murders in the Rue Morgue (despite the fact that his knowledge of the city came from an exhibition and not reality) to the London of Holmes to the village of Miss Marple to San Francisco of Hammett. In many cases it is as important a component as the detective character itself, or at least the detective is so entwined in his or her geography as to be impossible to conceive without it. This aspect of the detective novel probably reached if not its penultimate then its most obvious demonstration in Raymond Chandler’s Philip Marlowe and has continued through the LA detective tradition that Chandler founded (with considerable outside help from Hammett). The liveliness of that tradition together with the fact that Los Angeles is home to Hollywood have made it the most mapped city in public consciousness.
