You will begin to ask yourself questions before you are through the first two chapters of this gripping yarn. What was the mystery of the cottage in Devonshire? Why the Chinese atmosphere about the place? What was the curious Eastern odour? And what the voices in the night? Sexton Blake asked himself these same questions, too -and a very curious explanation he found! When you have started this yarn you won't need to worry what to do with the next hour or two of your time.
