There was silence. His glassy black eyes, blank and soulless, swept over us. His mouth curled in that smug, complacent smile. He had us with our shoulders to the floor. He knew it--and he knew we knew it. There was no possible way we could escape. We were two thousand feet above the earth. Our plane wouldn't get a quarter of a mile before the magnetic ray would bring it back. Parachute? Even supposing we could get parachutes where would we go? Drop two thousand feet into the middle of the Arabian Desert? My brain raced. Never before had I been in such a tight place. And soon--if Fraser had his way--I wouldn't even have a mind to think with! I felt choked, stifled. Was there no way out? It seemed to me that a blanket--a soft, terrible blanket of uncontrollable circumstance--was being folded around me, robbing me of the use of my limbs, paralyzing me, numbing me. And out of this terrible helplessness came again Fraser's voice. "I have told you enough," he said suavely, "so that you may have a faint idea of my power. I will send you now to Doctor Semple who will administer the serum and place you under the 'nourishment ray.' This is another of my discoveries," he added casually. "It is a ray which allows the patient to absorb, through the shell of the skin, sufficient nourishment, both solid and liquid, to last for twenty-four hours." * * * * * Five minutes later we stood in a small room that might have been the office of an up-to-date physician anywhere in the world. Across the polished top of a mahogany desk Dr. Semple stared at us, his eyes, like the eyes of our guide and Fraser, polished and expressionless. But now we understood. Those eyes were expressionless because there was nothing to give them expression. I tried to force my mind to comprehend the almost incomprehensible. We were among men who were not men! We were fast in the power of human beings who possessed no trace of humanity, who had become nothing but scientific Robots even though they still had bodies of flesh and blood! It was unbelievable! My hands grew cold and my brain hot at the thought. Yet, gazing into the bright, enamelled eyes of Dr. Semple, I knew it was true. Carefully, scientifically, we were prepared for our injections. And with every mechanical move of the doctor my mind seemed to take on fresh speed as it raced toward some solution to our terrible problem. My eyes flew around the tiny office searching for some means of escape. Doctor Semple turned to prepare the syringe. Behind his back Brice gestured frantically. Somehow I understood. In my pocket was a flask--a flask I had filled with drinking water in Constantinople. Bewildered, I handed it over to him.
