Charlie Chan in Rio

"Gee, Pop," Jimmy Chan says, "She doesn't look like a murderess." Number two son and his famous father share a table with the local police captain in a Rio nightclub, watching Lola Dean sing and dance—and waiting to arrest her for a murder back in Honolulu.

–Alas, Lola herself is murdered before they get the chance, and the Chans begin sorting through the usual suspects—a couple of romantic rivals, a secretary, a fiancé, a psychic who gives his clients spell-inducing cigarettes and also owns a recording machine….

A solid supporting cast fill their roles nicely, particularly Victor Jory as Marana, the psychic who offers his clients a "psychognosis" and is certainly up to something fishy. Kay Linaker also stands out as the purposeful personal secretary.

Sidney Toler and Sen Yung are excellent as usual as Charlie Chan and son Jimmy. The local policeman is played, as in multiple other Chan films, by Harold Huber—more restrained this time around, he's an actual detective rather than simple comic relief.

Iris Wong is cute as Lola's maid, Lili. Of course, Jimmy tries to impress her with his detective skills—"The case is in the bag. It's a cinch!"—and they have a little romance.

A memorable climax involves Mr. Chan volunteering to undergo Marana's coffee-and-cigarette hypnosis: Chan puffs and puffs, that little smile on his face, nothing happening, while the gathered suspects wait and wait….

No wasted motion in this one—short and sweet. The plot is unexceptional but the production and performances are absolutely solid: for simple entertainment value, this is one of the series' best.
