The Chinese Republican is of the mandarin class, but of a new generation which veneers its Confucianism with Western polish. These youthful and unbalanced reformers, in conjunction with older but no less ill-balanced provincial politicians, may be said to represent Young China. Amid such turmoils as this we invariably look for, and invariably find, a Third Party. In my opinion, Dr. Fu-Manchu was one of the leaders of such a party. Another question often put to me was: Where did the Doctor hide during the time that he pursued his operations in London? This is more susceptible of explanation. For a time Nayland Smith supposed, as I did myself, that the opium den adjacent to the old Ratcliff Highway was the Chinaman's base of operations; later we came to believe that the mansion near Windsor was his hiding-place, and later still, the hulk lying off the downstream flats. But I think I can state with confidence that the spot which he had chosen for his home was neither of these, but the East End riverside building which I was the first to enter. Of this I am all but sure; for the reason that it not only was the home of Fu-Manchu, of Karamaneh, and of her brother, Aziz, but the home of something else--of something which I shall speak of later. The dreadful tragedy (or series of tragedies) which attended the raid upon the place will always mark in my memory the supreme horror of a horrible case. Let me endeavor to explain what occurred. By the aid of Karamaneh, you have seen how we had located the whilom warehouse, which, from the exterior, was so drab and dreary, but which within was a place of wondrous luxury. At the moment selected by our beautiful accomplice, Inspector Weymouth and a body of detectives entirely surrounded it; a river police launch lay off the wharf which opened from it on the river-side; and this upon a singularly black night, than which a better could not have been chosen. "You will fulfill your promise to me?" said Karamaneh, and looked up into my face. She was enveloped in a big, loose cloak, and from the shadow of the hood her wonderful eyes gleamed out like stars. "What do you wish us to do?" asked Nayland Smith. "You--and Dr. Petrie," she replied swiftly, "must enter first, and bring out Aziz. Until he is safe--until he is out of that place--you are to make no attempt upon--" "Upon Dr. Fu-Manchu?" interrupted Weymouth; for Karamaneh hesitated to pronounce the dreaded name, as she always did. "But how can we be sure that there is no trap laid for us?" The Scotland Yard man did not entirely share my confidence in the integrity of this Eastern girl whom he knew to have been a creature of the Chinaman's. "Aziz lies in the private room," she explained eagerly, her old accent more noticeable than usual. "There is only one of the Burmese men in the house, and he--he dare not enter without orders!" "But Fu-Manchu?"
