Having been a fan of Charlie Chan I was not familiar with Mr Wong but to my surprise the story itself was worthy of a Charlie Chan. Over look Boris Karloff as an oriental will allow you to enjoy this film. Film opens fast with a frighten man seeking help from Mr Wong. His murder is a mind bender in the tradition of Chan films as no one can figure out how a man in a locked room is killed with the police right outside of the door. Many suspects and more of the mysterious murders makes this a film "most enjoyable" for the "detective" in each of us.
