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."
