Q1

Why is Boston Blackie arrested at the beginning of the movie?

Blackie is arrested while retrieving stolen gems from a safety deposit box at the Arcade Building. He was doing this as a favor to his friend Ed Barnaby, who had hidden the diamonds there after being paroled. The police suspect Blackie of theft and later of murdering Barnaby, but he is actually trying to help recover the jewels to protect them from criminals.

Foreshadowing: Barnaby's earlier decision to hide the diamonds in a bank box sets the entire plot in motion.

Q2

Where did Ed Barnaby actually hide the real diamonds?

Barnaby hid the real diamonds in a safe deposit box at the Arcade Building. He gave Blackie the key and asked him to retrieve the jewels for his daughter. However, when Blackie arrives at the box, he finds it empty, the crooks had already tortured Barnaby and stolen the diamonds before Blackie could recover them.

Foreshadowing: The empty box creates the central mystery that drives the second half of the movie.

Q3

How did Herschel end up with the real diamonds?

Herschel obtained the real diamonds after his associates Walsh and Beck tortured Ed Barnaby to learn the hiding place. The crooks retrieved the stones from Barnaby's deposit box before Blackie could reach them. Herschel then secretly kept the diamonds for himself rather than turning them over to Walsh, which later leads to Herschel being murdered.

Foreshadowing: Herschel's secret hoarding of the diamonds creates the tension that leads to his death.

Why does Walsh kill Herschel in the movie?

Walsh kills Herschel because he realizes Herschel has been keeping the real diamonds for himself. When Walsh and Beck attempt to exchange fake diamonds for Betty, Herschel returns too soon and the fakes are exposed. Walsh then confronts Herschel about producing the real diamonds, and when Herschel cannot deliver them, Walsh shoots him. Blackie witnesses the murder from hiding.

Foreshadowing: Herschel's greed in keeping the diamonds secret directly causes his downfall.

How do Blackie and Betty escape from the Flamingo Club?

Blackie and Betty escape during a wartime citywide blackout that plunges the area into darkness.

Blackie rigs the radio in Inspector Farraday's stolen car to transmit any conversation to the police. He then coaxes Walsh into talking by pretending to negotiate, getting Walsh to admit to killing Herschel and kidnapping Betty. Once Walsh confesses, Blackie turns him over to the authorities while the police listen in to the broadcast.

Why were fake diamonds used in the exchange for Betty?

Blackie had the Runt borrow a diamond brooch from Dixy Rose Blossom to test whether the stones the crooks possessed were real. Suspecting a switch, Blackie used fake diamonds during the exchange. The crooks didn't realize they were receiving fakes until Herschel returned too soon and exposed the scheme.

Foreshadowing: The fake diamonds plant the seeds for the climactic double cross.

Q8

Why is Dixy Rose Blossom arrested at the end of the movie?

Dixy Rose Blossom is arrested for bigamy during the Runt's interrupted wedding. The police arrest Dixy while the Runt's wedding to her is being postponed due to the chaos of the diamond case. This comic resolution ties up the subplot involving the Runt's troubled engagement.

Foreshadowing: The Runt's engagement has been postponed multiple times throughout the film due to the ongoing criminal events.

After failing to locate the hidden jewels, Walsh and Beck take Betty from Arthur Manleder's apartment where Blackie had placed her for safekeeping. They leave a ransom note demanding the diamonds in exchange for her freedom.

Foreshadowing: Blackie's earlier decision to hide Betty creates the vulnerability the crooks exploit.

Q10

Why does Blackie offer to give the diamonds to Walsh?

Blackie proposes trading the diamonds to Walsh in exchange for the location of Barnaby's body. This is a strategic move to recover his friend's remains for proper burial while also ensuring the diamonds don't fall into the wrong hands. The police close in during this exchange, forcing Blackie and Walsh to flee in Inspector Farraday's car.

Foreshadowing: This sacrifice shows Blackie's loyalty to his friend Barnaby despite the danger.
