"Two thousand feet above London there is a Palace of all delights. Immeasurable wealth, the genius of great artists have been combined to make a City of Enchantment. And in every garden with its plashing fountains, in its halls of pictures and delights, upon its aerial towers, down its gilded galleries, lurking at the banquet, mingling with the music, great shapes of terror squeak and gibber like the ghosts Shakespeare speaks of in ancient Rome." "Morse?" "There is a noble intellect overdone and dissolved in terror. In all other respects sane as you or I, my savior and benefactor, Gideon Morse is a maniac whose one sole idea is to preserve himself and his daughter from some horror, some vengeance which surely cannot threaten him." Twice, thrice I strode the attic. Then at last I stopped. "Will you help me now, Pu-Yi, will you take a letter from me, will you help me to meet Her, and soon?" He bowed his head for answer, and then, as he looked up again his face was suffused with a sort of bright eagerness that touched me to the heart. "I am yours," he said. "Then quickly, and soon, Pu-Yi, for you are only half informed. Gideon Morse may be driven mad by fear, no doubt he is. But it is _not_ an imaginary fear. It is a thing so sinister, so real and terrible, that I cannot tell you of it now. I am too exhausted by the events of this night. I will say only this, that within the last hour a faithful friend of mine has returned from the other side of the world and brings me ominous news." * * * * * I believe that Pu-Yi, whose movements were, of course, not restricted like those of the lower officials, returned to the towers in the early morning. As for me, I caught a workmen's train from Richmond station, slunk in an early taxi to Piccadilly with Arthur Winstanley, and slipped into lavender-clean sheets and silence till past noon, when Captain Patrick Moore arrived to an early lunch. Dressed again in proper clothes, with dear old Preston fussing about me with tears in his eyes, I felt a thousand times more confident than before. Old Pat had to be informed of everything, and as a preliminary I told him my whole story, from the starting-point of the "Golden Swan." "And now," I said, "here's Arthur, who has traveled thousands of miles and who has come back with information that fits in absolutely with everything else. He gave me an epitome last night, under strange and fantastic circumstances. Now then, Arthur, let's have it all clearly, and then we shall know where we are." Arthur, whose face was white and strained, began at once.
