"You can imagine my anxiety, gentlemen. I was quite at a loss to know what to do when my cousin told me the story of your adventures with that bunch of opium smugglers. That was late last night, and not wishing to disturb you, I put off my call until this morning. If you can find my intended, you will probably also solve the mystery of the disappearance of your partner. It is up to you." "Oh we will take up your case, of course, Mr. Lung," said Old King Brady. "Have you any idea what the motive for all this can be? Any starting clew to give us?" "None whatever. I am just as much in the dark over the matter as you are." "Suppose this Wang Foo wanted to marry the princess?" "Would he box her up and treat her as he has if he loved her?" put in Harry, speaking for the first time. "Listen," said Ah Lung, "Chinamen are not all fiends, as you may think." "I don't think so," retorted Harry. "There are white fiends as well as yellow fiends." "You are more liberal-minded than most of your race," replied the Chinaman, "but we will leave the white fiends out of the question. Yellow ones there certainly are in this town, and I greatly fear that it is into their hands the princess has fallen." "Is there money coming to the man who marries her?" demanded Old King Brady, abruptly. "That's just it. There was $20,000 of what you call dowry to go with the princess. As you are probably aware, among my people women rarely carry with them dowry. On the other hand, men who want to marry have to pay for their wives--buy them, you call it, though I never could understand where the difference comes in between paying for husbands, as is done right along in America. However, that is not the point. In this case it is different. The Princess Skeep Hup had in her own right $10,000, given to her by her mother. As our women do not take care of their own money matters, that money was to come to me. It was sent to me by mail in the form of a draft on the Bank of California, and I have it now, so that can't be the reason for kidnaping the princess, you see." "All of which makes the mystery additionally puzzling," said Old King Brady. "But now listen, you, Mr. Lung. There is but just one thing certain in this case outside of the fact that a voice from that box told Miss Montgomery that the Princess Skeep Hup was inside, which I, knowing her knowledge of Chinese, believe." "So do I," declared Ah Lung, emphatically. "I know Miss Montgomery by reputation, and can well believe it. But this one thing you speak of!" "Is the fact that the matter was managed by opium smugglers. If we can catch on to who these people were we may stand some chance of success in our chase after this Chinese princess." Ah Lung sat silent for some time. "What you say is true," he said at last. "I could help you in that if----" "Well, if?" "If I could feel sure that the Secret Service people would not interfere with me." "In other words, Lung & Lung sometimes deal in smuggled hop."
