Norden had to force himself to eat, for he had no apparent appetite. The psychiatrist leaned forward casually, watching him. "Would you like to tell us about it, Dr. Norden?" he asked. "Precisely what happened to Hardwick?"
Norden shook his head, while the tension mounted again. The man would be on the alert for hidden meanings in his words, and he wasn't quite ready for that. Yet he was afraid to risk putting it off. "I'm not sure I can tell much. I—well, everything's pretty foggy. A lot of it I can't remember at all."
"Partial amnesia is fairly common," the psychiatrist said reassuringly. "In fact, everyone has touches of it. Try going back a bit—say to your childhood—to give you a running start. We've got plenty of time."
Norden had little interest in his childhood, and he skimmed over it with a few words. He'd done nothing unusual until he'd drifted into the new investigation of radiation outside the electromagnetic spectrum in his post-graduate college work. Then he'd suddenly developed, caught fire, and become something of a genius.
He was the first man ever to prove there was more than theory involved. He'd been called to Mars for the Widmark Interplanetary Award for his brilliant demonstration of protogravity after he'd floated two ounces of lead with a hundred thousand dollars worth of equipment that used twenty kilowatts of power.
In fifteen years at Mars Institute, he'd discovered four new types of extraspectral radiation, become a full professor, and had almost discovered how to harness nuclear binding energy.
Then the Aliens had come. They had appeared abruptly near Pluto, apparently coming at a speed greater than that of light, in strange globular ships that defied radar detection. Without provocation or mercy, they had sought out and destroyed every settlement between Pluto and Saturn, and had begun moving inward, systematically destroying all life in their path.
Nobody had ever seen an Alien—they invariably exploded to dust before they could be captured—but the horror of their senseless brutality was revealed in the hideous human corpses they left behind them.
Norden had been drafted while there was still optimism. Men could build a hundred ships to the Aliens' one, equally radar-proof, free from danger of magnetic or electronic detection, and nearly invisible in space. In anything like an even battle, men were certain to win. But they soon discovered it wasn't an even battle.
The Aliens had some means of detecting human ships accurately at distances of millions of miles, and blasting them with self-guided torpedoes, while remaining undetected themselves. And behind the torpedoes would come the dark globular ships to spray the wreckage with some force that left every cell utterly lifeless.
