Albert saw no reason to hide it, but there was no sense in revealing anything. The Patrol had word of his arrest by now and should be here any moment. It was as though Kemmer had read his mind. "Don't count on being rescued. I stopped the Patrol report." Kemmer paused, obviously enjoying the expression on Albert's face. "You know," he went on, "there's a peculiar fact about nerves that maybe you don't know. A stimulus sets up a brief neural volley lasting about a hundredth of a second. Following that comes a period of refractivity lasting perhaps a tenth of that time while the nerve repolarizes, and then, immediately after repolarization, there is an extremely short period of hypersensitivity." "What's that to do with me?" Albert asked. "You'll find out if you don't answer promptly and truthfully. That gadget on your arm is connected to a polygraph. Now do you want to make a statement?" Albert shook his head. He was conscious of a brief pain in one finger, and the next instant someone tore the finger out of his hand with red hot pincers. He screamed. He couldn't help it. This punishment was beyond agony. "Nice, isn't it?" Kemmer asked as Albert looked down at his amputated finger that still was remarkably attached to his hand. "And the beauty of it is that it doesn't even leave a mark. Of course, if it's repeated enough, it will end up as a permanent paralysis of the part stimulated. Now once again--who gave you that information?" * * * * * Albert talked. It was futile to try to deceive a polygraph and he wanted no more of that nerve treatment--and then he looked into Kemmer's mind again and discovered what went into brainwashing. The shock was like ice water. Hypersensitive stimulation, Kemmer was thinking gleefully, would reduce this fat slob in the chair to a screaming mindless lump that could be molded like wet putty. Albert felt helpless. He couldn't run and he couldn't fight. But he wasn't ready to give up. His perception passed over and through Kemmer with microscopic care, looking for some weakness, something that could be exploited to advantage. Kemmer _had_ to have a vulnerable point. He did. There was a spot on the inner lining of the radial vein in Kemmer's left arm. He had recently received an inoculation, one of the constant immunizing injections that were necessary on Antar, for there was a small thrombus clinging to the needle puncture on the inner wall of the vessel. Normally it was unimportant and would pass away in time and be absorbed, but there were considerable possibilities for trouble in that little blob of red cells and fibrin if they could be loosened from their attachment to the wall. Hopefully, Albert reached out. If he couldn't move himself, perhaps he could move the clot.
