Eleanor and Leggett, still searching for her husband Frank, visit a favorite club of Frank's called Man Loh's Oriental Roof Gardens where club dancers Sammy and Susie suggest they try Sullivan's Grotto, a bar across the street. Susie tells Leggett he reminds her of a portrait drawing that Frank had given her and Leggett realizes it must have been Frank's recollection of the killer he had witnessed. This doesn't bode well for the unsuspecting Susie.
They leave the Roof Garden and cross the street to Sullivan's Grotto (below).
Then ... This is Commercial Street in Chinatown looking east from Grant Avenue. The Roof Gardens is the building with the arched doorway on the far left at 776 Commercial.
... and Now, Chinatown mercifully hasn't changed much since then. 776 Commercial is the green building.
Then ... Leggett briefly excuses himself from the bar (below, the door behind him) and sneaks across the street back to the Roof Gardens. He returns with the drawing and tears it up before rejoining Eleanor.
When Leggett returns (below), bar owner Sullivan confides that Frank had just been there before heading off to an Army and Navy store to get a change of clothes.
They leave the bar to the sound of wailing sirens as passersby gather round the body of young Susie who had fallen from the balcony of the Roof Gardens. The ruthless Leggett had silenced her once and for all.
Then ... the passersby are standing in front of the club, 776 Commercial.
