I came across an old copy of this in my library's stacks. I'm a sucker for old mysteries, and obviously knew of this one by reputation, but let's just say I was still unprepared for the horrific racism and sexism in this book. The plot is very exciting...as long as you are prepared to accept at face value that the fate of the White Race is on the line at the hands of the sinister Chinese, and to read a great deal of pretty outrageous accusations and characterizations along these lines. Should probably be kept out of the hands of the average Trump voter, who would be sadly likely to take the whole thing at face value.
