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?" now Macklin—" 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 the headaches had caused him to be absent from his classes for several "I imagine he will," Mitchell said. "Macklin's always seemed a decent Elliot Macklin entered in a cloud of pipe smoke and a tweed jacket. He Macklin dropped on the edge of the desk and adjusted his pipe. "Now Macklin nodded. "That's right, Steven. Migraine." "Yes," Macklin said. "I see. Are you two saying you have such a shot? Can you cure headaches?" "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 the end of the race as well," Macklin said. "In certain areas it is A colony of virus in the brain cells will relax the cerebral vessels—and only the cerebral vessels—so that the cerebrospinal fluid makes me violently sick to my stomach. But it's better than the migraine. How should I go about removing my curse?" He reinserted the pipe. Macklin coughed. "I don't want to overestimate my value but the "I'm tempted," Macklin said hesitantly, "but the answer is go. I mean Macklin ran the back of his knuckles across his forehead. "I really "That's not so bad," Macklin said. "How low can it get?" 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 Macklin groped in his pocket for a pen. "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 "What do you mean by that, Mrs. Macklin," Mitchell said sharply. "Mrs. Macklin! I think I had better talk to you later when you are calmer." Mitchell dropped the receiver heavily. "What could be wrong with Macklin?" he asked without removing his hand from the telephone. "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." Macklin's traditional ranch house was small but attractive in "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 used to be a mathematical genius." "And now?" Mitchell said impatiently. "Now he is a moron," the medic said. other. "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 according to all the standard intelligence tests we have given you, your clinical intelligence quotient is that of a moron." "That's just on book learning," Macklin said. "There's a lot you learn "But—" Mitchell said, impatient to examine Macklin for himself. "Very Mitchell did his best to explain the F-M Virus. "You mean," the Army officer said levelly "you have infected him with some kind of a disease to rot his brain?" "No, no! Could I talk to the other man, the doctor? Maybe I can make him understand." "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. the cerebrum. It isn't more than necessary to stop headaches. But that 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. is replaceable. But the chances of an Elliot Macklin are very nearly "Just a moment," Mitchell interrupted, "we can cure Macklin." "Just you wait a second now, boys," Elliot Macklin said. He was leaning Mitchell coughed into his fist for an instant, to give him time to 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. 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 They found Mrs. Macklin in the dining room, her face at the picture "Mrs. Macklin," the colonel began, "these gentlemen believe they can "Y-yes," Colonel Carson said, "but he's not himself.

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 paralyze. To kill. No court would give you that authority." "I suppose there's some chance of that. But without the treatment there is no chance of your husband regaining his right senses, Mrs. 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." "What is she? A monster?" the Army officer muttered. "No," Mitchell said. "She's an intelligent woman unconsciously jealous of her husband's genius."
