Consequently it was no surprise to the detectives to have this Chinaman at once allude to it.

"Mr. Brady," he began, "I want you if you will to take up an important matter for our firm, which you will find upon investigation, if you are not already aware of it, stands high in San Francisco commercial circles."

Old King Brady had heard of the firm of Lung & Lung, and said so. He doubted, however, if he cared to take up a case for them.

"It is work you are already engaged in," replied Ah Lung quickly. "It concerns the Chinese princess, Skeep Hup, who disappeared along with your Miss Montgomery the other day."

"What do you know about that?" demanded Old King Brady, "and who told you?"

"My information comes through my cousin, who is interpreter at police headquarters," replied Ah Lung. "I am prepared to tell you what I know of the Chinese princess. I suppose the information will interest you in any case."

"It certainly will," said the old detective. "Fire away, Mr. Lung. This puts altogether a different face on the matter."

"It is this way," continued Ah Lung. "I have had frequent occasion in the course of business to visit China, and, being a merchant, am allowed to come and go as I please. When in Pekin, some three years ago, I was introduced to this Chinese princess, as you have called her. She is not actually a member of the Imperial family, but the daughter of a very wealthy Mandarin. I fell in love with her, and it was finally arranged that we should marry. It was my intention to go to China after her, but the illness of my brother Wun prevented it, so she started to come to me. I supposed her to be a passenger on the Manchuria, the last steamer in from China. I was so informed by letters I received, but when I went to meet her at the wharf, I was surprised to learn that her name was not on the passenger list. Both the purser and the steward informed me that she had not been seen on the steamer.

"I immediately cabled to China, but it was only to be told that she had started for Shanghai with the intention of taking passage on the Manchuria, and that it was supposed by the family that she had done so. She traveled from Pekin in company of a man named Wang Foo, a cousin of hers. This person was to return to Pekin after seeing the princess off. He had failed to put in an appearance at the time the answer to my cablegram was sent, nor had anything been heard from him.

"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."
