This film provides examples of:

- Asshole Victim: Helen
- Berserk Button: Buzz really, really dislikes "monkey music".
- Coincidental Broadcast: Johnny is chatting with Joyce over breakfast at a beachside hotel. As Johnny is getting ready to leave, a radio that was completely silent before suddenly pipes up from somewhere offscreen with a report about the death of Helen Morrison.
- Dead Man Writing: Johnny pulls a picture of his son out of a frame, and reveals a note from Helen, telling him that if something happens to her, Harwood's name is actually Bauer, and he's wanted for murder in New Jersey.
- Executive Meddling: The killer was originally supposed to be Buzz, but the U.S. Navy objected to the idea of one of its service members committing a murder and persuaded the studio to have Chandler rewrite the ending.
- Even Evil Has Standards: Leo and a Mook overpower Johnny. The mook goes through Johnny's pockets and finds the incriminating note from Helen. Leo, who didn't approve of the mook lifting the money from Johnny's wallet, promptly clubs the mook over the head and says "There's ethics in this business, the same as any other."
- Gray Rain of Depression: The rain is pouring as Johnny leaves the bungalow after finding out about both Helen's infidelity and the truth of their son's death.

- Pig Latin: "Well well well, unkdray again", says the maid, except Helen isn't drunk, she's dead.
