The Sorcerer was clad in a snaky yellow robe, and those hideous hands and that terrible head were more pronouncedly reptilian than ever. He turned his great yellow eyes toward me, like pools of livid fire, and his parchment-thin lips moved in what probably passed for a smile. I staggered erect and gripped the bars, cursing. "Gordon, curse you, where is Gordon?" Kathulos took a test-tube from the table, eyed it closely and emptied it into another. "Ah, my friend awakes," he murmured in his voice--the voice of a living dead man. He thrust his hands into his long sleeves and turned fully to me. "I think in you," he said distinctly, "I have created a Frankenstein monster. I made of you a superhuman creature to serve my wishes and you broke from me. You are the bane of my might, worse than Gordon even. You have killed valuable servants and interfered with my plans. However, your evil comes to an end tonight. Your friend Gordon broke away but he is being hunted through the tunnels and can not escape. "You," he continued with the sincere interest of the scientist, "are a most interesting subject. Your brain must be formed differently from any other man that ever lived. I will make a close study of it and add it to my laboratory. How a man, with the apparent need of the elixir in his system, has managed to go on for two days still stimulated by the last draft is more than I can understand." My heart leaped. With all his wisdom, little Zuleika had tricked him and he evidently did not know that she had filched a flask of the life-giving stuff from him. "The last draft you had from me," he went on, "was sufficient only for some eight hours. I repeat, it has me puzzled. Can you offer any suggestion?" I snarled wordlessly. He sighed. "As always the barbarian. Truly the proverb speaks: 'Jest with the wounded tiger and warm the adder in your bosom before you seek to lift the savage from his savagery.'" He meditated awhile in silence. I watched him uneasily. There was about him a vague and curious difference--his long fingers emerging from the sleeves drummed on the chair arms and some hidden exultation strummed at the back of his voice, lending it unaccustomed vibrancy. "And you might have been a king of the new regime," he said suddenly. "Aye, the new--new and inhumanly old!" I shuddered as his dry cackling laugh rasped out. He bent his head as if listening. From far off seemed to come a hum of guttural voices. His lips writhed in a smile. "My black children," he murmured. "They tear my enemy Gordon to pieces in the tunnels. They, Mr. Costigan, are my real henchmen and it was for their edification tonight that I laid John Gordon on the sacrificial stone. I would have preferred to have made some experiments with him, based on certain scientific theories, but my children must be humored. Later under my tutelage they will outgrow their childish superstitions and throw aside their foolish customs, but now they must be led gently by the hand.
