"It's hitting everybody," Bettijean said helplessly. "Not many kids so far, thank heavens. But housewives, businessmen, office workers, teachers, preachers—rich, poor—from Florida to Alaska. Just when you called me in, one of the girls thought she had a trend. The isolated mountain areas of the West and South. But reports are too fragmentary." "What is it?" he cried suddenly, banging the desk. "People deathly ill, but nobody dying. And doctors can't identify the poison until they have a fatality for an autopsy.

Sucking air through his teeth, he reached for his phone and directory. He dialed until every finger of his right hand was sore. He spoke to worried doctors and frantic hospital administrators and hysterical nurses. His firm, fine penmanship deteriorated to a barely legible scrawl as
