If you're volunteering to watch a Charlie Chan movie, you already have some idea of what's in store, and as this is one of the late ones done at the Poverty Row Studio, Monogram, you may also know it's not heavy on either production values or a complex script.

That said, director Phil Karlson sets up the first five minutes as if this were a dynamic, lurking-in-the-shadows film noir, and immediately slips from dark, shadowy streets into a brightly-lit diner where the juke-box is also a one-way television which connects to a secret room somewhere else in the city; what's not to like? Sounds like the start of a fascinating mystery! Unfortunately, the remainder of the film doesn't develop many more startling innovations or follow up much with the television, getting lost somewhere as the script pages went missing, perhaps

There are, however, character treats along with way, such familiar folks as George Chandler as a cynical soda jerk and familiar-face Addison Richards as a suspicious bank guard; the 64 minutes are well-spent for the average "B" movie fan--but this ain't The Maltese Falcon although almost any hour spent with Charlie Chan can be unadulterated escapism.
