"They tunneled up from beneath," I answered. "The Temple of Dreams is directly connected with the warehouse." "I have traversed the alley between the two buildings," said Gordon, "and the doors of the warehouse opening into that alley are, as I have said, nailed shut from without just as the owners left them. There is apparently no rear exit of any kind from the Temple of Dreams." "A tunnel connects the buildings, with one door in the rear room of Yun Shatu's and the other in the idol-room of the warehouse." "I have been in Yun Shatu's back room and found no such door." "The table rests upon it. You noted the heavy table in the center of the room? Had you turned it around the secret door would have opened in the floor. Now this is my plan: I will go in through the Temple of Dreams and meet the Master in the idol-room. You will have men secretly stationed in front of the warehouse and others upon the other street, in front of the Temple of Dreams. Yun Shatu's building, as you know, faces the waterfront, while the warehouse, fronting the opposite direction, faces a narrow street running parallel with the river. At the signal let the men in this street break open the front of the warehouse and rush in, while simultaneously those in front of Yun Shatu's make an invasion through the Temple of Dreams. Let these make for the rear room, shooting without mercy any who may seek to deter them, and there open the secret door as I have said. There being, to the best of my knowledge, no other exit from the Master's lair, he and his servants will necessarily seek to make their escape through the tunnel. Thus we will have them on both sides." Gordon ruminated while I studied his face with breathless interest. "This may be only a snare," he mattered, "or an attempt to draw me away from Sir Haldred, but----" I held my breath. "I am a gambler by nature," he said slowly. "I am going to follow what you Americans call a hunch--but God help you if you are lying to me!" I sprang erect. "Thank God! Now aid me with this suit, for I must be wearing it when I return to the automobile waiting for me." His eyes narrowed as I shook out the horrible masquerade and prepared to don it. "This shows, as always, the touch of the master hand. You were doubtless instructed to leave marks of your hands, encased in those hideous gauntlets?" "Yes--though I have no idea why." "I think I have--the Master is famed for leaving no real clues to mark his crimes--a great ape escaped from a neighboring zoo earlier in the evening and it seems too obvious for mere chance, in the light of this disguise. The ape would have gotten the blame of Sir Haldred's death." The thing was easily gotten into and the illusion of reality it created was so perfect as to draw a shudder from me as I viewed myself in a mirror.
