This second Mr. Wong film was given a bigger budget than the first, actually has some exterior scenes, and is a much more polished production. Boris Karloff is excellent as usual in his suave and quiet manner as the brilliant amateur Chinese detective of San Francisco. In this film, we learn more about him. We discover that he has degrees from both the University of Heidelberg and Oxford University. There is certainly no doubt about his high intelligence and his profound knowledge of Chinese literature and art. He is a connoisseur who is familiar with most types of precious Chinese objects. And hence it is that he is familiar with the background of the object which is at the centre of this story, a precious imperial gem known as The Eye of the Daughter of the Moon. It turns out that in the recent sack of Nanking (today called Nanjing) by the Japanese, numerous priceless gems, jades, and works of art from an Imperial Collection there have been pillaged and made their way into the hands of private collectors. The most priceless of all of these is the gem just mentioned which has been illegally acquired by a rich collector who is very soon murdered. There are two very annoying performances in this film. One is by Grant Withers as the Detective Inspector, shouting and over-acting as usual. The other is Dorothy Tree, who simply can't act at all. However, one ignores these faults in the interest of following the good story. Otherwise it is an excellent film, and lots of villains are to be found.
