The Hawk knew the answer to the question he curtly asked. "Its purpose, Dr. Ku?"
"That," came the suave reply, "it will be your pleasure to discover for yourself. I can promise you some novel sensations. Nothing harmful, though, however much they may tire you. Now!" He gave a sign; one of his assistants touched a switch. The wire ball rose, leaving the central seat free for entrance. "All is ready. May I ask you to enter?"
Hawk Carse faced his old foe. There was stillness in the laboratory then as his bleak gray eyes met and held for long seconds Ku Sui's enigmatic green-black ones.
"If I don't?"
For answer the Eurasian gestured apologetically to his guards.
"I see," Carse whispered. There was nothing to be done. Three coolies, each with ray-guns at the ready; four white assistants.... No hope. No chance for anything. He looked at the negro. "Don't move, Friday," he warned him. "They'll only shoot; it can do no good. Eight to two are big odds when the two are unarmed."
He turned and faced the Eurasian, holding him with his eyes. "Ku Sui," he said, clipping the words, "you have said that this would not permanently harm me, and, although I know you for the most deadly, vicious egomaniac in the solar system, I am believing you. I do not know you for a liar.... I will enter."
The faint smile on the Oriental's face did not alter one bit at this. Carse stepped to the metal seat and sat down.
The web of shimmering wires descended, cupping him completely. Through them he saw Ku Sui go to a switchboard adjoining and study the indicators, finally placing one hand on a black-knobbed switch and with the other drawing from some recess a little cone, trailing a wire, like a microphone. A breathless silence hung over the laboratory. The white-clad figures stood like statues, dumb, unfeeling, emotionless. The watching negro trembled, his mouth half open, his brow already bedewed with perspiration. But the only sign of strain or tension that showed in the slender flaxen-haired man sitting in the wire ball in the center of the laboratory, came when he licked his dry lips.
