Macklin was playing jacks. "Do you think we'll have to use force on Macklin to get him to "Hello?" Elliot Macklin said. carried away for a moment. But Macklin is exactly what we need for a Macklin had answered the "Sure," Macklin said, "if you say so. Why shouldn't I believe you?" "I suppose so," Macklin said humbly. "You've found yourself worrying—thinking—about a lot of other problems since we left you, haven't you? Maybe not the same kind of now Macklin—" able to frame an argument with it. Macklin was in his early fifties but For the past seven years Macklin—who "If you say so," Macklin said uncertainly. . The only thing that could delay the project was Macklin's health. Despite his impressive body, some years before he had suffered a mild "I imagine he will," Mitchell said. "Macklin's always seemed a decent "Yes," Macklin said. "How can you have a specific for a number of different causes?" Macklin "That's fine," Macklin said, sucking on his pipe. "And this effect that telencephalon section of the frontal lobes. It's caused by an over-production of the pituitary gland. We have artificially bred a "That may mean the end of headaches, but I would think it would mean the end of the race as well," Macklin said. "In certain areas it is works, I could stop using that damned gynergen, couldn't I? The stuff makes me violently sick to my stomach. But it's better than the Macklin coughed. "I don't want to overestimate my value but the We can cure the headaches of one person and that's the limit of our resources." "I'm tempted," Macklin said hesitantly, "but the answer is go. I mean ' no Macklin ran the back of his knuckles across his forehead. "I really "That's not so bad," Macklin said. "How low can it get?" Macklin held his head in both hands. "Why did you two select "Yes, I do," Macklin said. "Very well. Go ahead. Give me your Macklin groped in his pocket for a pen. unverified results to the press. It's too early for that!" "Don't be so stuffy and conservative, Mitchell! Macklin's cured, isn't he? By established periodic cycle he should be suffering hell right "It's Macklin's wife," Ferris said. "Do you want to talk to her? I'm no heroin." "That's absurd. What makes you think a thing like that?" "The—trance he's in now." "Mrs. Macklin! I think I had better talk to you later when you are Macklin?" he asked without removing his hand from the telephone. "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 "You are the gentlemen who gave Dr. Macklin the unauthorized suddenly realized Macklin used a pipe as a form of masculine protest to used to be a mathematical genius." "And now?" Mitchell said impatiently. "Now he is a moron," the medic said. III "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. "I beg your pardon, sir," Carson said. "I didn't intend any offense. "But—" Mitchell said, impatient to examine Macklin for himself. "Very "All I want to know is why Elliot Macklin has been made as simple as if 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. might just as well have blown up Washington, D.C. Better! The capital is replaceable. But the chances of an Elliot Macklin are very nearly once in a human race." "Just you wait a second now, boys," Elliot Macklin said. He was leaning 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." 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. "That's right, Colonel. There's no use in arguing with him," Mitchell said. "It's not his decision to make," the colonel said. "He's an idiot now." "No, Colonel. As you said, he's a moron. He seems an idiot compared to his former level of intelligence but he's legally responsible. There are millions of morons running around loose in the United States. They can get married, own property, vote, even hold office. Many of them do. You can't force him into being cured.... At least, I don't think you can." "Y-yes," Colonel Carson said, "but he's not himself. He refused the treatment. He wants to remain in his state of lower intelligence." She nodded. "If those are his wishes, I can't go against them." was my original thought. But I've redecided." "Redecided!" Carson burst out almost hysterically. "Yes. 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, where he never had a moment's peace from worry and pressure. He's happy now. Like a child, but happy." restore your husband's mind we will be forced to get a court order declaring him incompetent." "But he is not! Legally, I mean," the woman stormed. the edge where restoring the mind of Elliot Macklin was concerned. Once he's certified incompetent, authorities can rule whether Mitchell and Ferris' antitoxin treatment is the best method of restoring Dr. Macklin to sanity." "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." "No," Mitchell said. "She's an intelligent woman unconsciously jealous of her husband's genius." "Maybe," Carson said. "I don't know. I don't know what the hell to tell the Pentagon. I think I'll go out and get drunk."
