The terribly evil Dr. Fu-Manchu returns to London and completely baffles the entertainingly racist British detectives pursuing him. This is the second book in the series, and a lot of fun for two reasons. On one hand it is exciting and melodramatic, and on the other it is a glimpse into the mindset of the author, writing at a time when the "Yellow Peril" was seen as a scientifically proven reality. Reading this book is both an absorbing diversion and an interesting comparison to the hidden racism in our own time.
