Mr. Wong, mestarisalapoliisi

Although most of the production is pretty plain, the basic mystery story in "Mr. Wong, Detective" is rather interesting, and Boris Karloff's good performance as the detective also makes it worth seeing. Karloff brought a human touch to every role that he played, and even though this is an atypical part for him, he is a believable Mr. Wong. Most of the other characters are somewhat nondescript, except for Grant Withers's abrasive police officer, and aside from Karloff the cast is nothing special, but the story itself is enough to hold your interest.

In the story, the detective must patiently solve a mystery from the slightest of clues. Some of the developments strain credibility, but if you can accept the premise, it's an interesting idea and it makes decent use of the details. There are several places where it could have been written better or edited more effectively, but the pacing is pretty good, and as it proceeds, it often gives you what you need to know in order to try to anticipate what happens next.

The climactic sequence is one of the better ones that you'll see in this kind of B-movie. The production values are lower than a Karloff feature deserves, but with a solid story and Karloff in the lead, it's definitely worth seeing.
