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.

The doctor turned, swabbed a patch of iodine on our arms, reached for the syringe. As he leaned over, Foulet thrust forward a foot. The doctor tripped, sprawled full length on the floor. Foulet and I quickly stooped to pick him up, standing between him and Brice—shielding his eyes so that he could not see. We fumbled to give Brice time. We apologized and soothed. Out of the tail of my eye I could see Brice working like lightning—emptying out the syringe of that villainous liquid, filling it with clear water.

It was done! We raised the doctor to his feet; gave his clothes a final brush. But as we stood back I know my hands were trembling and I had to clamp my teeth to keep them from chattering. Were we out of danger yet? Would the doctor discover our ruse? And, if we got out of his office without receiving the terrible injection, could we successfully fool Fraser and his "slaves" into believing we were mad? Fool them until we got a chance to escape? Could we simulate that glassy stare? Were we sufficiently good actors to get away with it? The questions pounded and raced through my brain in that instant when Doctor Semple turned again to his desk and picked up the syringe.

But the miracle happened! Mechanically he gave us the injection—never suspecting that it was not the devilish liquid he had put in, but only clear water! Then he stepped back and watched us. Cold chills raced up and down my spine. What were we supposed to do now? What was the action of the serum? Did it act at once or slowly? Was it supposed to make us sick? Did it send us to sleep? How could we simulate symptoms when we had no idea what these symptoms were supposed to be? But the cold voice of the doctor cut sharply across my agonized questions.

"You will lie down here," he said, opening a door into a room whose trails were lined with bunks, like an opium den. "In half an hour I will come for you. By that time—" His lips spread in that same travesty of a smile Fraser had employed.

We filed into the room and the door closed behind us. Obediently we lay down on the narrow bunks. We dared not speak. We scarcely dared glance at each other. We must act, at all times, as if we were observed. Might not Fraser have a ray that could penetrate walls? Might he not, even now, know that we had outwitted the doctor and had not received the fatal injection? And what then? Suppose Fraser himself superintended another injection? I pulled my thoughts back from the terrible supposition. One thing at a time. So far all had gone well. I lay down on the bunk and closed my eyes.

Half an hour later we heard the door open. Now, I, thought, when I look up, I am supposed to be mad! I struggled to make my mind a blank. I tried to force into my eyes that peculiar, brilliant, shiny, vacant expression I had noticed. Would I succeed?

I raised my eyes. The doctor was standing before us. With a gesture he bade Foulet go to him. I watched beneath lowered lids. Thank God he had called Foulet first. Foulet had dabbled in the psychology of insanity. Foulet would know how to act, and I would ape him. Coldly, mechanically Doctor Semple ran him through a few tests. I watched with bated breath. The doctor nodded. Foulet had passed!

It was my turn. I did exactly as Foulet had done—and succeeded! I had to turn away swiftly so that the doctor wouldn't see the gleam of triumph in my supposedly mad eyes.

He motioned to Brice. But just as Brice stepped forward the door opened and Fraser came into the room. For an instant everything reeled. We were gone! But even in that terrible instant of despair I remembered to keep my eyes blank. No trace of expression must appear or we were lost. I stretched my lips in that travesty of a smile I had seen the others use. Fraser stared at us, one after the other. He nodded.

"It is well," he said slowly and distinctly as if he were talking to small children. "Your names will still be as they were." We stared at him blankly and again he nodded. "You have forgotten your names—ah! Yours," he pointed to me, "was Ainslee, and it still is. And you are Monsieur Foulet. But Brice—" he paused. My heart hung in my breast, suspended there with terror. What was the matter with Brice? What did Fraser suspect—or know? He turned to the doctor. "You will give Inspector Brice another injection," he said. "The Inspector has a strong mind, and a clever one. A normal injection would not be enough."

It seemed to me that my blood froze. In that terrible instant it ran, like tingling ice, through my veins. Brice! The brainiest man in Scotland Yard! For Fraser was right. Brice had more brains than Foulet and I together. And in another half hour Brice would be no better than an idiot! For I didn't fool myself. Even Brice couldn't outwit Doctor Semple twice.

"You will follow me," said Fraser, turning to Foulet and me. "I will put you under the nourishment ray while Doctor Semple attends to Brice." Obediently, with slightly shuffling, gait and vacant eyes we followed him into an adjoining room, leaving Brice behind. I didn't even trust myself to glance at him as we left. But my heart was in my boots. When would we see him again? And what would he be?

The room we entered was dark, but instantly Fraser switched on a mellow, orange-colored light, that flooded the room with a deep, warm glow.

"Strip yourselves and sit down," he said, pointing to deep lounging chairs that filled the room. "You will do nothing. Relax and allow the light to bathe you. In half an hour I will come back with instructions."

We obeyed, I imitating blindly every vague, mechanical movement of Foulet's. We settled ourselves in the comfortable chairs and Fraser left us. He had told us to relax—but to do anything else would have been impossible. The light soothed us, eased us; gave us, somehow, a penetrating sensation of peace and complete comfort. It flowed around us, warming us, lulling us to a delicious dreamy state that was neither waking nor
