After a time there came a dull click and a sleepy answer. me for help Macklin had answered the phone instead of his wife. "Oh, you want to know if my wife is around. No, she's asleep. That Army doctor, Colonel Sidney, he gave her a sedative. I wouldn't let him give me anything, though." "No!" the smaller man yelled. "You can't expect me to violate professional ethics and test my own discovery on myself." 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 Ferris paced off the tidy measurements of the office outside the Elliot Macklin entered in a cloud of pipe smoke and a tweed jacket. He Macklin threw a big arm across Ferris' shoulders. "How have you been, "Doctor, we understand you have severe headaches," Mitchell said. Macklin nodded. "That's right, Steven. Migraine." cause of headaches," Mitchell announced. produces headaches is?" "The pressure effect caused by pituitrin in the brain," Mitchell said eagerly. "That is, the constriction of blood vessels in the telencephalon section of the frontal lobes. It's caused by an over-production of the pituitary gland.

My wife would like it even less." tend it in a worn leather case. "Tell me," he said, "what is the worst that could happen to me?" "Low blood pressure," Ferris said. "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 "Ferris!" Mitchell yelled, slamming the laboratory door behind him. "Don't be so stuffy and conservative, Mitchell! Macklin's cured, isn't he? By established periodic cycle he should be suffering hell right now, shouldn't he? But thanks to our treatment he is perfectly happy, with no unfortunate side effects such as gynergen produces." "But—" The shrill call of the telephone interrupted Mitchell's objections. Ferris excused himself and crossed to the instrument. He answered it "It's Macklin's wife," Ferris said. "Do you want to talk to her? I'm no "Hysterical?" Mitchell muttered in alarm and went to the phone. "Hello?" Mitchell said reluctantly. "Mrs. Macklin?" She couldn't have sounded calmer or more self-possessed, Mitchell thought. "That's right, Mrs. Macklin. I'm Dr. Steven Mitchell, Dr. Ferris's "What do you mean by that, Mrs. Macklin," Mitchell said sharply. "That's absurd. What makes you think a thing like that?" "The—trance he's in now." "Now, Mrs. Macklin. Neither Dr. Ferris or myself have been near your husband for a full day. The effects of a narcotic would have worn off by this time." "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. 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.

This is Dr. Ferris. I am Dr. Mrs. Macklin was an attractive brunette in her late thirties. She wore "What's wrong with him, Sidney?" the other officer asked the doctor. "Not a thing," Sidney said. "He's the healthiest, happiest, most well-adjusted man I've ever examined, Carson." "But—" Colonel Carson protested. The medic examined Mitchell and Ferris critically before answering. "He Mitchell and Ferris stared at Colonel Carson and Macklin and at each "What did he mean, Macklin is an idiot?" Mitchell asked. Ferris followed them docilely. 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." "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." Mitchell looked back at Macklin. "Where did his wife get to, Colonel? They found Mrs. Macklin in the dining room, her face at the picture "But Mrs. Macklin!" Mitchell protested. "You will have to get a court order overruling your husband's wishes." She smoothed an eyebrow with the third finger of her right hand. "That was my original thought.

To 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 "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."
