envelope that he almost dropped it. Eight clippings were inside, small teleprinted scissorings from digest newssheets that were available at any street-corner dispenser. He read them quickly, and was more puzzled than before until he realized that they fell into two general groups of interlocking similarities. Four were accounts of unexplained disappearances. A moderately successful research chemist named Ellis had vanished from the offices of his New York chemical firm; a neighborhood pharmacist in Minneapolis, a spinster tea-shop proprietress in Atlanta and a female social worker in Los Angeles had disappeared with equal thoroughness, completely baffling the efforts of police to find them. None of these people had been of more than minor importance, even in his own immediate circle. Alcorn felt that these events had been reported only because the efficiency of missing-persons bureaus made permanent disappearance next to impossible. Even so, only one clipping—that on Ellis, the New York chemist—bothered to run a photograph. The other four accounts dealt with violent deaths, all rising from sudden outbreaks of mob hysteria. Two of the victims had been small-town clergymen, a profession which made their lynchings as startling as they were inexplicable; both had been respected members of their little communities until the day—the date was less than a week old—their congregations rose up en masse and tore them limb from limb. The remaining two of the second group had died in different fashions. A doctor in a Nevada mining hamlet, making a late call, had been set upon by the patient's family, knocked unconscious and shot. A Girl Scout leader in Mississippi had been thrown over a cliff by her young charges. A morbid and pointless collection of horrors, Alcorn thought, until he saw the parallel that related them. The circumstances were strikingly similar in every case except that the four who disappeared were urbanites, while the murdered ones were all members of small and comparatively isolated communities. Not one of the eight had been over thirty-five; each had been well-liked; none was wealthy, yet all were in comfortable circumstances from vocations that depended upon good will. A further similarity built up in Alcorn's subconscious, but died unconsidered because at that moment the quarterstaff bout on the screen ended and a brazen-voiced announcer gave the time.
