“Have you been dosing yourself pretty regularly with these things?”

“Well … uh … well, yeah. Sometimes.” He smiled feebly. “Sometimes I didn’t feel so good, and I didn’t want to bother the medics. You know how it is.”

“Very considerate, I’m sure,” said Smathers with just the barest trace of sarcasm, which, fortunately, fell unheeded on MacNeil’s ears. “But which ones did you take every day?”

“Just the vitamins.” He paused. “And … uh … maybe an aspirin. The only things I took real regular were the vitamins, though. That’s all right ain’t it? Ain’t vitamins food?”

“Sure, son, sure. What did you take yesterday morning, before you got so sick?”

“Just the vitamins,” MacNeil said stoutly. “I figured that since you docs was takin’ care of me, I didn’t need no medicine.”

Dr. Smathers glanced up hopelessly at the other two men. “That eliminates the vitamins,” he said, sotto voce. He looked back at the patient. “No aspirin? No APC’s? You didn’t have a headache at all?”

MacNeil shook his head firmly. “I don’t get headaches much.” Again he essayed a feeble smile. “I ain’t like you guys, I don’t overwork my brains.”

“I’m sure you don’t,” said Smathers. Then his eyes gleamed. “You have quite a bit of stomach trouble, eh? Your digestion bad?”

“Yeah. You know; I told you about it. I get heartburn and acid stomach pretty often. And constipation.”
