There’s That Woman Again

Private detective Bill Reardon is awakened by his dizzy wife Sally, who cannot remember what the string tied to her finger is supposed to remind her of. They discuss their struggling detective agency over breakfast, highlighting their financial difficulties and her memory lapse. Bill receives a call from their only client, Mr. Stone, demanding an explanation for missing an important meeting.

Reardon hurriedly meets with Mr. Stone, the jewelry store manager Mr. Davis, and Mrs. Nacelle to discuss recent robberies at the store. Reardon reveals his belief that Charles Crenshaw, a clerk, is the prime suspect in the thefts. The meeting sets the stage for the investigation into the jewelry store crimes.

Charles Crenshaw arrives at the Reardon agency seeking help because he's being followed and searched. Sally pretends to be a detective to assist in the case. Unbeknownst to Crenshaw, the man following him and searching his apartment is actually Bill Reardon, the detective himself.

Reardon has lunch with Mrs. Nacelle, who reveals that her husband took over the store from Davis due to debt. She hints that Davis resents losing the store and possibly could be the thief, adding suspicion to the case. Their conversation deepens the mystery surrounding the thefts.

Sally overhears her husband Reardon suspecting Crenshaw and leaves the restaurant hastily. She plans to warn Crenshaw by calling the jewelry store clerk, showcasing her concern for the suspect's innocence and her active role in the investigation.

Reardon and his agents arrest Crenshaw, believing he is connected to the jewel thefts. This action demonstrates the ongoing suspicion and the detective's efforts to crack the case based on the evidence and assumptions at that point.

At a nightclub, Davis leaves a note for mob boss Tony Croy, raising suspicions. Croy arrives and inquires about the note, which was actually picked up by someone else. Davis then follows Croy in a cab after leaving the nightclub, hinting at underworld connections.

Davis reads a note revealing a location in the store's filing cabinet and goes to investigate. He is shot by an unseen attacker at the store, suggesting a setup or a trap linked to the note and underlying crimes.

Sally devises a risky plan to retrieve stolen items from the store while Crenshaw is incarcerated, aiming to prove his innocence. She steals jewelry using keys from Mrs. Nacelle's purse, attempting to provide evidence against the real culprit.

Reardon uncovers that Croy and Mrs. Nacelle are married but never divorced. Croy has been blackmailing Mrs. Nacelle to steal jewelry from the store, revealing the motive behind the crimes and the true criminal mastermind.

Mrs. Nacelle tricks Croy into opening a safe rigged to fire a gun, catching him in her scheme. She seeks to eliminate Croy after settling the blackmail, showing her willingness to use violence to secure her secrets.

Back at the store, Bill Reardon demonstrates that Davis was killed by a trick gun concealed inside the file drawer, which was also used in Mrs. Nacelle's home to kill Croy. The evidence implicates Mrs. Nacelle in the murders and thefts.

Reardon and Sally set a trap for Mrs. Nacelle, leading to her final confrontation with the police. The case is solved, with Nacelle's scheme unraveled and justice served, bringing an end to the complex web of deception and crime.
