"The existence of such a passport," continued Max, "would seem to point to the fact that all the members of this organisation are not known personally to one another. At the same time those invited or expected at present _may_ be known to Ah-Fang-Fu or to whoever acts as concierge. You see? Expected or otherwise, I assume that 'Le Balafre' would be admitted--and at night I shall pass very well for 'Le Balafre'--somewhat damaged as a result of my encounter with the late Charles Malet, but still recognisable!" "And I?" "You will be 'franked' in. The word of 'Le Balafre' should be sufficient for that! Of course I may be conducted immediately into the presence of the Chief--'The Scorpion'--and he may prove to be none other than Miguel, for instance--or my Algerian acquaintance-- or may even be a 'she'--the fascinating Zara el-Khala! We do not know. But I _think_--oh, decidedly I think--that the cowled one is a male creature, and his habits and habitat suggests to me that he is a Chinaman." "And in that event how shall you act?" "At once! I shall hold him, if I can, or shoot him if I cannot hold him! Both of us will blow police-whistles with which we shall be provided and Inspectors Dunbar and Kelly will raid the premises. But I am hoping for an interval. I do not like these inartistic scrimmages! The fact that these people foregather at an opium-house suggests to me that a certain procedure may be followed which I observed during the course of the celebrated 'Mr. Q' case in New York. 'Mr. Q.' also had an audience-chamber adjoining and opium den, and his visitors went there ostensibly to smoke opium. The opium-den was a sort of anteroom." "Weymouth's big Chinese case had similar features," said Inspector Dunbar, who re-entered at that moment carrying a leathern grip. "If you are kept waiting and you keep your ears open, doctor, that's when your knowledge of the lingo will come in useful. We might rope in the whole gang and find we hadn't a scrap of evidence against them, for except the attempt on yourself, Dr. Stuart, there's nothing so far that I can see to connect 'The Scorpion' with Sir Frank Newcombe!" "It is such a bungle that I fear!" cried Max. "Ah! how this looped-up lip annoys me!" He adjusted the bandage carefully. "We've got the place comfortably surrounded," continued Dunbar, "and whoever may be inside is booked! A lady, answering to the description of Mlle. Dorian, went in this evening, so Sowerby reports." Stuart felt that he was changing colour, and he stooped hastily to inspect the contents of the bag which Dunbar had opened. _"Eh bien!"_ said Gaston Max. "We shall not go empty-handed, then. And now to transfigure you, my friend!" CHAPTER VII IN THE OPIUM DEN
