"What you have learned about the Atomic Ray," Shelby cut in, "you learned through your own efforts. If you can steal the remainder of the necessary information from my brain, you are welcome. Otherwise, I urgently invite you to go to the devil."
Hekki's face assumed a look of infinite though make-believe sadness. It was a trick such as a designing woman might use to attract some desirable male.
"I am sorry to hear you talk so, Mr. Shelby," he said. "But as you suggest, I believe that there are ways of stealing knowledge even from your mind. For instance, in an old vault beneath my palace at Taboor, I once found a sealed vat containing a certain fluid. The Ancient Ones were wise, for when they desired any man to talk, they thrust his arms or his legs, or perchance his whole body into the fluid. Very slowly, and with some discomfort, it ate away the tissue of his nerves. I must leave you now, my friend. Think well, and may the gods that rule the universe guide you on the right course."
He opened the door. Shelby caught a glimpse of a long hall, and at the far end, the bewildering maze of control-room equipment. The panel closed.
CHAPTER V
The Race Through Space
Immediately the Earthman set himself to the task of examining everything in his prison. But as he had expected, there was little or nothing to discover. The walls which his tether permitted him to reach were all perfectly smooth and solid. He realized with a sheepish grin that it had been foolish of him to even dare to hope that they would be otherwise. The chain fastened to the fetter was quite adequate to hold him. The window, even if it might have been used as an avenue of escape, was securely fastened with bolts, so that it would have taken a man equipped with a heavy set of wrenches, an hour to remove it. To shatter the flexible pane was next to an impossibility. The table was firmly welded to the floor. Beyond the table, Shelby could not go, for the chain prevented him. But he was quite sure that there was nothing movable in the entire room massive enough to be used as a tool or weapon.
He slumped down on his bunk, and let one hand rest on a small power-pipe which ran along the wall and up to the illumination globe above. For a minute dejection almost got a firm grip on him. But he fought it off. This was no time to give up. Why, the struggle hadn't even started yet!
Shelby felt a faint vibration of the power-pipe under his hand. For a considerable time the impressions had been coming to him, but they had scarcely penetrated into his consciousness. They seemed no more significant than the hundred and one little noises and disturbances that go with the running of any space ship. Presently however, the regular sequence of the pulsations attracted his attention. Something made him think of the almost obsolete Morse code. Then the realization came to him. Someone in another room on he ship was tapping on the power-pipe—signaling—signaling him! He spelled the word out—A-u-s-t-i-n, repeated over and over again.
