I loved Keye Luke in everything he did and always wanted to see this film. He is good but very subdued in his portrayal of a young James Lee Wong. The Monogram production is really bottom of the barrel and the whole film plays out listessly. Not a terrible film but nothing really to recommend it unless you love this genre.

Obviously, Boris Karloff couldn't convince anyone that he was the Chinese amateur detective James Lee Wong without piling on Chinese schtick. Keye Luke didn't need to do this, and his more natural performance is an amazing relief from all the white guys playing Asians we've seen from Warner Oland's Fu Manchu and Charlie Chan to Christopher Lee's Fu Manchu and Joel Grey's Master Chiun. Wong in this movie is smarter and more knowledgeable, particularly on things Chinese, than the cops, but he's a completely natural and believable figure. (All right, he occasionally does a little bit of proverb schtick when speaking to other Chinese.) Wong's servant is a comic relief character but redeems himself by getting the better of the cops at one point. Lotus Long provides a nice romantic interest. It's too bad this is Luke's only starring role.
