Full Plot Summary
The film Mr. Wong, Detective (1938) begins with a scene in San Francisco, where the leader of the Dayton Chemical Company, Simon Dayton, shows up at the house of a private detective, James Lee Wong, in a near state of panic. Dayton tells of burglaries, threats and efforts to spy on him and he is convinced that somebody wants him dead because of some strong new poison gas his company intends to export to foreign countries.
Wong accepts to investigate it and scheduling a meeting with Dayton in his office the following day. By the time Wong arrives at Dayton Chemical the building is already in crisis. Manager of the office Russell, secretary Myra Ross, and chemist Carl Roemer have been fighting Dayton and the police have been summoned to quell the disturbance.
Roemer, a scientist who actually developed the gas, barged in with a gun demanding fair payment and recognition, claiming Dayton stole his formula. Once Roemer has been pushed out and officers arrive, Wong joins Captain Sam Street of the SFPD to check on Dayton.
Dayton’s office door is locked from the inside. When it is opened, they find Dayton dead at his desk, with no visible injuries. The attending doctor suggests a heart attack, and Street is quick to assume that Roemer’s earlier outburst makes him the obvious killer.

Wong looks closer. On the floor near Dayton’s body he notices tiny fragments of glass. After testing them and examining the office ventilation, he concludes that Dayton was killed by a small hollow glass globe filled with poison gas—the same gas Dayton’s company intends to export. Someone triggered the globe inside the sealed office, making the death look natural from the outside.
While Street continues to press Roemer based on his anger and motive, Wong widens the suspect field. Dayton’s partners, Theodore Meisel and Christian Wilk, would inherit his share of the highly profitable business and might prefer to control the gas formula themselves. Myra Ross appears loyal but has access to Dayton’s papers and schedule, and there are hints that not everyone in the office is telling the whole truth.
At the same time, there are signs of international intrigue. A shadowy figure named Baron Von Krantz, actually Anton Mohl, and an elegant woman using names like Olga Petroff and Countess Dubois are watching the company’s shipments and staff. These foreign agents fear the gas may be used against their own people and are trying either to stop the shipment or control the formula.
As Wong digs deeper, more deaths follow. Associates connected to Dayton and the gas project die under similar circumstances, with locked spaces and mysterious collapses pointing again to the glass‑globe gas method. Each new body complicates the puzzle: motives range from revenge and financial gain to political sabotage.
Wong quietly examines each crime scene, checks laboratories and shipping records, and interviews suspects with calm courtesy, while Captain Street chases more obvious leads and pushes heavily on Roemer. Myra Ross unofficially sides with Wong, helping him gather documents and offering insight into office politics.
In the final act, Wong pieces everything together. He discovers how the gas globes were placed and triggered in locked rooms, who had both the technical knowledge and access, and how the foreign agents intersect with the greed of Dayton’s circle. In a classic drawing‑room reveal, Wong assembles the suspects, explains the mechanism of the murders, dismisses the red herrings, and identifies the real killers whose scheme combines industrial espionage with personal profit.
Captain Street finally accepts Wong’s conclusions, the guilty parties are arrested or neutralized, and the deadly formula is secured. The film closes with Wong returning to his quiet routines, the model of a polite, methodical detective ready for his next case—setting up the sequels that follow.
Genre and Key Themes
Mr. Wong, Detective 1938 film sits firmly in the crime‑mystery genre, blending a locked‑room puzzle with a light espionage angle. It belongs to the “gentleman detective” tradition, where a cultured, observant sleuth solves crimes by thinking more clearly than everyone else.
Key themes include:
- Brain over brawn: Wong cracks the case by being patient, thinking like a forensicist, and staying close up instead of throwing his gun around.
- Appearance is deceitful: The most emotional and loud suspect (Roemer) does not necessarily kill and respectable businessmen can conceal the most sinister intentions
- Fear of modern weapons: The formula of poison gas also represents the 30s nervousness of chemical warfare and the fact that science can be turned into an instrument of wealth or politics.
- Prejudice and respect: Wong is a respected figure, even by the adversaries, despite being stereotyped in a casual manner in the past: he is shown as an educated, polite, and quietly authoritative individual who enjoys respect even among opponents.
- Reason as justice: When all is said and done the intelligent reasoning will clear up misunderstandings, vindicate the innocent, and uncover intricate conspiracies.
These concepts make the movie, Detective full movie feel more than a typical B-movie, despite the fact that the production is basic.

Movie Review
The film Mr. Wong, Detective (1938) is a well-acted, small-budget mystery that is lifted out of its small-budget origins primarily by the acting of Boris Karloff and a genuinely fascinating central mystery.
- Performance: Karloff portrays Wong as quiet, accurate, and confident without using overdone accents and providing the character with solemn weight. Grant Withers is well cast as Captain Street, who is unassailable, impatient, and Maxine Jennings is light and airy, as Myra Ross. Evelyn Brent also brings a twist to the story as the woman of changing identities regarding the spy ring.
- Plot and pacing: William Nigh maintains the story as straight forward, largely fast moving and follows the crime scene to clue with minimum of filler. It might be that some of the viewers feel that Wong is observing rather than acting, but that Nash, almost C.S.I., approach of doing things is part of his charm as a thinker and not as a fighter.
- Novelty and design: The locked-room poisoning using globes of glass gas is a nice hook and the additional elements of business competition and foreign spies ensure that the stakes are fascinating. The fans of these genres may even guess some of the solution in advance, but the resolution scene at the end also provides the satisfaction that would be found in a 1930s detective story.
- Production values: With it being a Monogram film, sets and camera work are not extravagant, but the background of the San Francisco and interior of offices fulfil their purpose. The simplicity of the style used in the film gives it a light and easy to follow style that allows contemporary audiences who find the movie under the free classic movies or through the public domain webpage to find the movie.
Contemporary viewers can also observe and wonder at the practice of having a white actor as an Asian protagonist of the time. In that contentious context, Karloff is playing Wong in a reserved and dignified manner.
All in all, Mr. Wong, Detective (1938) film may be considered a nice piece of late-1930s film noir: it is not a flashy one but still rather intelligent, well-timed, and accompanied by one of the most familiar faces of the classic Hollywood.
