Macklin was playing jacks. "How are you going to go about forcing him, Doctor?" Mitchell inquired. "He outweighs you by fifty pounds and you needn't look to me for help against that repatriated fullback." Ferris fingered the collar of his starched lab smock. "Guess I got He lay there, blinking the sleep out of his eyes, listening to his Macklin had answered the heart race, and then convulsively snatched the telephone receiver from "No!" the smaller man yelled. "You can't expect me to violate professional ethics and test my own discovery on myself." Elliot Macklin had inherited the reputation of the late Albert Einstein his Theory of Spatium was correct or not because no one had yet been able to frame an argument with it. Macklin was in his early fifties but looked in his late thirties, with the build of a football player. The . The only thing that could delay the project was Macklin's health. Despite his impressive body, some years before he had suffered a mild stroke ... or at least a vascular spasm of a cerebral artery. It was known that he suffered from the vilest variety of migraine. A cycle of "Aspirins would still be used to reduce fever and relieve muscular "How can you have a specific for a number of different causes?"

"In certain areas it is valuable to have a constriction of blood vessels." works, I could stop using that damned gynergen, couldn't I? The stuff makes me violently sick to my stomach.

"That's not so bad," Macklin said. "How low can it get?" "When your heart stops, your blood pressure goes to its lowest point," Mitchell said. A dew of perspiration had bloomed on Macklin's forehead. "Is there much Macklin held his head in both hands. "Why did you two select "You're an important man, doctor," Ferris said. "Nobody would care if Macklin groped in his pocket for a pen. "Doctor—Harold—you shouldn't have given this story to the "Don't be so stuffy and conservative, Mitchell! Macklin's cured, isn't "It's Macklin's wife," Ferris said. "Do you want to talk to her? I'm no "Mrs. Macklin! I think I had better talk to you later when you are Macklin?" he asked without removing his hand from the telephone. Bud and Lou, much the same. "I don't know. Maybe they just have tired blood," Mitchell ventured. "Iron deficiency anemia?" "Never mind, doctor. It was a form of humor. I think we had better see exactly what is wrong with Elliot Macklin." "There's nothing wrong with him," Ferris snapped. "He's probably just trying to get us in trouble, the ingrate!" Macklin's traditional ranch house was small but attractive in dum-de-de-dum-dum-dum . As they waited Mitchell glanced at Ferris. He seemed completely Mrs. Macklin was an attractive brunette in her late thirties. She wore "You are the gentlemen who gave Dr. Macklin the unauthorized The colonel smiled thinly. "Dr. Macklin is my concern. And everything suddenly realized Macklin used a pipe as a form of masculine protest to The Army physician stood up and brushed his knees, undusted from the "But—" Colonel Carson protested. "Oh, he's changed all right," the Army doctor answered. "He's not the same man as he used to be." The medic examined Mitchell and Ferris critically before answering. "He used to be a mathematical genius." "And now?" Mitchell said impatiently. "Now he is a moron," the medic said. "What did he mean, Macklin is an idiot?" Mitchell asked. "Not an idiot," Colonel Carson corrected primly. "Dr. Macklin is a moron. He's legally responsible, but he's extremely stupid." "I'm not so dumb," Macklin said defensively. "But—" Mitchell said, impatient to examine Macklin for himself. "Very "You mean," the Army officer said levelly "you have infected him with "All I want to know is why Elliot Macklin has been made as simple as if he had been kicked in the head by a mule," Colonel Carson said. "I think I can explain," Ferris interrupted. necessary amount of control to stop pain is too much to allow the brain cells to function properly." "Why won't they function?" Carson roared. "They don't get enough food—blood, oxygen, hemoglobin," Ferris explained. "The cerebral vessels don't contract enough to pump the blood through the brain as fast and as hard as is needed. The brain cells remain sluggish, dormant. Perhaps decaying." The colonel yelled. Mitchell groaned. He was abruptly sure Ferris was correct. "Just a moment," Mitchell interrupted, "we can cure Macklin." "What do you mean you don't like it?" Carson demanded. He added, "Sir?" "I figure you mean to put me back like I used to be." frame an answer. "Unfortunately, yes. Apparently if your mind functions properly once again you will have the headaches again. Our research is a dismal failure." "I wouldn't go that far," Ferris remarked cheerfully. Macklin slowly shaking his head. "No, sir!" the mathematician said. "I shall not go back to my original state. I can remember what it was like. Always worrying, worrying, worrying." Macklin nodded. "Troubled, anyway. Disturbed by every little thing. what was an infinity anyway? All that sort of schoolboy things. It's peaceful this way. My head doesn't hurt. I've got a good-looking wife and all the money I need. I've got it made. Why worry?" said. "It's not his decision to make," the colonel said. "He's an idiot now." They found Mrs. Macklin in the dining room, her face at the picture "Y-yes," Colonel Carson said, "but he's not himself.

I can't go against Elliot's wishes. It would be monstrous to put him back where he would suffer the hell of those headaches once again, "Mrs. Macklin," the Army man said levelly, "if you don't help us declaring him incompetent." "But he is not! Legally, I mean," the woman stormed. he's certified incompetent, authorities can rule whether Mitchell and Ferris' antitoxin treatment is the best method of restoring Dr. Macklin to sanity." "Because, Colonel, the matter of my husband's health, his very life, is "It isn't quite the same, Colonel. Elliot Macklin has a history of vascular spasm, a mild pseudostroke some years ago. Now you want to give those cerebral arteries back the ability to constrict. To Macklin," Mitchell interjected. Her mouth grew petulant. "I don't care. I would rather have a live husband than a dead genius. I can take care of him this way, make him comfortable...." "I'm no psychiatrist," Mitchell said, "but I think she wants Macklin stupid. Prefers it that way. She's always dominated his personal life, and now she can dominate him completely." Carson squinted. "Any particular reason, doctor?"
