Scene when Bogie chases his "Dead Wife" into the apartment building...
...and the landlady denies anyone living in that flat reminds me of "Vertigo", when Jimmy Steward follows Kim Novak and Ellen Corby reacts the same way.
shareThe straw that broke the camel's back point? When fats Greenstreet suggests they take a different foot route back to the lodge. They come across the logs stacked below similarly to the death scene. Hump is too (bright) to go any further in this charade. It's his victory moment.
Another thing=He would not have chased the sister until said coast was clear. She had no intention of marrying the Drake character. She was waiting for her sister to be found (dead)---so she could feel entitled to Bogart. & vice versa.
