The dacoits whom the Chinaman had brought to England originally numbered seven, we learned. As you, having followed me thus far, will be aware, we had thinned the ranks of the Burmans. Probably only one now remained in England. They had lived in a camp in the grounds of the house near Windsor (which, as we had learned at the time of its destruction, the Doctor had bought outright). The Thames had been his highway. Other members of the group had occupied quarters in various parts of the East End, where sailormen of all nationalities congregate. Shen-Yan's had been the East End headquarters. He had employed the hulk from the time of his arrival, as a laboratory for a certain class of experiments undesirable in proximity to a place of residence. Nayland Smith asked the girl on one occasion if the Chinaman had had a private sea-going vessel, and she replied in the affirmative. She had never been on board, however, had never even set eyes upon it, and could give us no information respecting its character. It had sailed for China. "You are sure," asked Smith keenly, "that it has actually left?" "I understood so, and that we were to follow by another route." "It would have been difficult for Fu-Manchu to travel by a passenger boat?" "I cannot say what were his plans." In a state of singular uncertainty, then, readily to be understood, we passed the days following the tragedy which had deprived us of our fellow-worker. Vividly I recall the scene at poor Weymouth's home, on the day that we visited it. I then made the acquaintance of the Inspector's brother. Nayland Smith gave him a detailed account of the last scene. "Out there in the mist," he concluded wearily, "it all seemed very unreal." "I wish to God it had been!" "Amen to that, Mr. Weymouth. But your brother made a gallant finish. If ridding the world of Fu-Manchu were the only good deed to his credit, his life had been well spent." James Weymouth smoked awhile in thoughtful silence. Though but four and a half miles S.S.E. of St. Paul's the quaint little cottage, with its rustic garden, shadowed by the tall trees which had so lined the village street before motor 'buses were, was a spot as peaceful and secluded as any in broad England. But another shadow lay upon it to-day--chilling, fearful. An incarnate evil had come out of the dim East and in its dying malevolence had touched this home. "There are two things I don't understand about it, sir," continued Weymouth. "What was the meaning of the horrible laughter which the river police heard in the fog? And where are the bodies?" Karamaneh, seated beside me, shuddered at the words. Smith, whose restless spirit granted him little repose, paused in his aimless wanderings about the room and looked at her.
