Post Street, San Francisco, California (Google Maps ⧉, OpenStreetMap ⧉)

"Spade said: "Mr. Cairo? This is Spade. Can you come up to my place--Post Street--now? . . . Yes, I think it is."

"Post Street was empty when Spade issued into it. He walked east a block, crossed the street, walked west two blocks on the other side, recrossed it, and returned to his building without having seen anyone except two mechanics working on a car in a garage."

"Spade went, partly by way of an alley and a narrow court, from his office‐building to Kearny and Post Streets, where he hailed a passing taxicab."
