Kirth-Labbery managed to laugh at himself. "Damn your secretarial hide, Vyrko. I love you like a son, but if I had one man who knew a meson from a metazoon to help me in the laboratory...."

"You'll find something, Father," Lavra said vaguely.

Her father regarded her with an odd seriousness. "Lavra," he said, "your beauty is the greatest thing that I have wrought—with a certain assistance, I'll grant, from the genes so obviously carried by your mother. That beauty alone still has meaning. The sight of you would bring a momentary happiness even to a man choking in his last spasms, while our great web of civilization...."

He absently left the sentence unfinished and switched on the video screen. He had to try a dozen channels before he found one that was still casting. When every erg of a man's energy goes to drawing his next breath, he cannot tend his machine.

At last Kirth-Labbery picked up a Nyork newscast. The announcer was sneezing badly ("The older literature," Vyrko observed, "found sneezing comic...."), but still contriving to speak, and somewhere a group of technicians must have had partial control of themselves.

"Four hundred and seventy-two planes have crashed," the announcer said, "in the past forty-eight hours. Civil authorities have forbidden further plane travel indefinitely because of the danger of spasms at the controls, and it is rumored that all vehicular transport whatsoever is to come under the same ban. No Rocklipper has arrived from Lunn for over a week, and it is thirty-six hours since we have made contact with the Lunn telestation. Yurp has been silent for over two days, and Asia a week.

"'The most serious threat of this epidemic,' the head of the Academy has said in an authorized statement, 'is the complete disruption of the systems of communication upon which world civilization is based. When man becomes physically incapable of governing his machines....'"


It was then that they saw the first of the yellow bands.

It was just that: a band of bright yellow some thirty centimeters wide, about five meters long, and so thin as to seem insubstantial, a mere stripe of color. It came underneath the backdrop behind the announcer. It streaked about the casting room with questing sinuosity. No features, no appendages relieved its yellow blankness.
