heard about it was four months ago. Considering what’s happened since then, it seems a lot longer.” He inhaled deeply from his brandy snifter before continuing. “As head of the development labs for NAC&M, I was asked to take part as a witness to a demonstration that had been arranged through some of the other officers of the company. It was to take place out on Salt Lake Flats, where—” It was to take place out on Salt Lake Flats, where there was no chance of hanky-panky. Richard Thorn—who held a Ph.D. from one of the finest technological colleges in the East, but who preferred to be addressed as “Mister”—was in a bad mood. He had flown all the way out to Salt Lake City after being given only a few hours notice, and then had been bundled into a jeep furnished by the local sales office of NAC&M and scooted off to the blinding gray-white glare of the Salt Flats.
