Who taught you to shoot, dead-eye? he thought, as the man continued to run. At the end of the hall, the man turned abruptly into one of the offices-to-be, his pursuer only five yards behind him. Afterwards, Karnes thought it over time after time, trying to find some flaw or illusion in what he saw. But, much as he hated to believe his own senses, he remained convinced. The broad window shed enough light to see everything in the room, but there wasn't much in it except for the slightly iridescent gray object in the center. It was an oblate spheroid, about seven feet high and eight or nine feet through. As Karnes came through the door, he saw the man step through the seemingly solid material into the flattened globe.
