Blow darts and air rifles seem to abound in the Charlie Chan series. It seems that those most vulnerable are not protected very well. So often, someone dies with a cop standing guard outside the door. People are able to shoot through windows or off balconies without any trouble. They then escape without a trace. Even if they are caught, the person lies dead. In this one, a Chinese princess has come to see Charlie with what appears to be important information. Birmingham goes to get Charlie and while they are putzing around, the unfortunate lady gets shot with a dart. It turns out that there is some big money involved with airplane contracts. A Chinese ship and some banking mishaps are at the center. Enter another of those dull 1940's policemen and an overly aggressive female beat reporter who has the hots for him and Chan is left having to handle the situation. As usual, Mantan Moreland and Tommy Chan get in the way for the most part. Roland Winters has replaced the late Sidney Toler and doesn't seem to have any chemistry with the secondary characters. Several people die as a result of carelessness. One thing I have noted before is the general insensitivity of Charlie and the gang. But then it's not Shakespeare.
