In a few more seconds a miracle of complicated wiring came into visibility. The silk fibers were seen to be wires, threads of silver gossamer that interconnected the five emerging bulks in a maze of ordered complexity. Thousands interlaced the interior; hundreds were gathered in each of five close bunches that sprouted from the floor of the case and then spread, fanwise, to various groupings of delicate liquid-immersed instruments. In several seconds more Eliot Leithgow and Hawk Carse were staring with horror at what the now brilliantly glowing liquid revealed the five shapes to be. As one man they rose, went to the cabinet and gazed with terrible fascination. "Brains!" exclaimed Leithgow. "Human brains! But not alive--surely not alive!" "But yes," contradicted the triumphant Eurasian. "Alive." * * * * * Five human brains lay all immersed in the glowing case, each resting in a shallow metal pan. There were pulsings in narrow gray tubes which led into their under-sides--theatrical evidence that the brains held imprisoned there were, as the Eurasian had said, alive--most strangely, unnaturally and horribly alive. Stark and cruelly naked they lay there, pulsing with life that should not have been. "Yes, alive!" repeated Ku Sui. "And never to die while their needs are attended!" One of his long artistic fingers tapped the glass before the central brain, which was set somewhat lower than the others. "This," he said, "is the master brain. It controls and coordinates the thoughts of the others, avoiding the useless, pursuing the relevant and retaining the valuable. It is by far the most important of the five, and is, of course the superior intellect. It is the keystone of my gateway to all power." Eliot Leithgow's face was deathly white, but, as one in the grip of some devilish hypnotic fascination, he could not tear his eyes away from the revolting, amazing achievement of his brilliant enemy. The Eurasian with the cruelty of a cat picked that awful moment to add: "This master brain is all that was best of Master Scientist Cram." The frail old man took this statement like a blow. "Oh, dear heaven--not Raymond Cram! Not Cram, the physicist, brought to this! Why, I knew him when----" Ku Sui smiled and interrupted. "But you speak of him as if he were dead! He's not. He's very much alive, as you shall see. Possibly even happy--who knows? There is no good---- _Keep back, Carse!_" * * * * * His tiger's eyes had not missed the adventurer's slight crouch in preparation for a shove which might have toppled the case and ended the abominable servitude of its gruesome tenants. The Hawk was caught before he had well started; and had he not stopped his gathering muscles he would have been dead from the coolie-guards' rays by the time he touched the near side of the case.
