cigarette, he tried to focus on the tangle of thoughts that spun through his head. Doctors, writers, society matrons, office workers—Aspen, Taos and college towns—thousands of people sick—but none in that valley in Tennessee—and few government workers—just one girl in his office—and she was sicker and more frightened about a letter—and.... "Hey, wait!" Andy yelled. Everyone in the room froze as Andy spun around, dashed to Bettijean's desk and yanked out the wide, top drawer. He pawed through it, straightened, then leaped across to the desk Janis had used. He snatched open drawer after drawer. In a bottom one he found her purse. Ripping it open, he dumped the contents on the desk and clawed through the pile until he found what he wanted. Handing it to the lab technician, he said, "Get me a report. Fast." The technician darted out. Andy wheeled to Bettijean. "Get the brass in here. And call the general first." To the doctor, he said, "Give that girl the best of everything." Then he ducked back to his own office and to the pile of reports. He was still poring over them when the general arrived. Half a dozen other brass hats, none of whom had been to bed, were close behind. The lab technician arrived a minute later. He shook his head as he handed his hastily scribbled report to Andy. It was Bettijean who squeezed into the office and broke the brittle silence. "Andy, for heaven's sake, what is it?" Then she moved around the desk to stand behind him as he faced the officers. "Have you got something?" the brigadier asked. "Some girl outside was babbling about writers and doctors, and dentists and college students, and little secretaries and big secretaries. Have you established a trend?" Andy glanced at the lab report and his smile was as relieved as it was weary. "Our problem," he said, "was in figuring out what a writer does that a doctor doesn't—why girls from small offices were sick—and why senators and postal workers weren't—why college students caught the bug and people in a Tennessee community didn't. "The lab report isn't complete. They haven't had time to isolate the poison and prescribe medication. But"—he held up a four-cent stamp—"here's the villain, gentlemen." The big brass stood stunned and shocked. Mouths flapped open and eyes bugged at Andy, at the stamp.
