leave the alcohol alone. I'd just have the luck to be finishing a drink when our friend, the Nipe, popped in on us. And when I do meet him, I'm going to need every microsecond of reflex speed I can scrape up."
They walked down a soft-floored, warmly lit corridor to an elevator which whisked them up to the main level of the Neurophysical Institute Building.
Another corridor led them to a room that might have been the common room of one of the more exclusive men's clubs. There were soft chairs and shelves of books and reading tables and smoking stands, all quietly luxurious. There was no one in the room when the three men entered.
"We can have some privacy here," Dr. Farnsworth said. "None of the rest of the staff will come in until we're through."
He walked over to a table, where an urn of coffee radiated soft warmth. "Cream and sugar over there on the tray," he said as he began to fill cups.
The cups were filled and the three men sat down in a triangle of chairs before any of them spoke again. Then Bart Stanton said:
"I made the remark that if the Nipe doesn't have time to eat his victims he just beats them to death, and you started to say something, Colonel."
Colonel Mannheim took a sip from his cup before he spoke. "Yes. I was going to say that, according to the evidence we have, he always beats his victims to death, whether he manages to eat them or not."
"Oh?" Stanton looked thoughtful.
"Oh, he's not cruel about it," the colonel said. "He kills quickly and neatly. The thing is that he never, under any circumstances, uses any weapons except the weapons that nature gave him—hands or feet or claws or teeth. He never uses a gun or a knife or even a club. Dr. Yoritomo has some theories about that which I won't go into now. He'll tell you about them pretty soon."
Stanton thought about the Japanese scientist and smiled. "I know. Dr. Yoritomo has threatened to tell me all kinds of theories."
"And believe me he will," said Mannheim with a soft chuckle. He took another sip of his coffee and then looked up at Stanton. "You've been through five years of hell, Mr. Stanton. In addition, you've been pretty much isolated here. Dr. Farnsworth, here, has tried to keep you informed, but, as I understand it, it has only been during the last few months that you've actually been able to absorb and retain information reliably. At least, that's the report I get. How do you feel about it?"
Bart Stanton thought for a moment. It was true that he'd been out of touch with what had been going on outside the walls of the Neurophysical Institute for the past five years. In spite of the reading he'd done and the newscasts he'd watched and the TV tapes he'd seen, he still had no real feeling for the situation.
There had been long hazy periods during that five years. He had undergone extensive glandular and neural operations of great delicacy, many of which had resulted in what could have been agonizing pain without the use of suppressors. As a result of those operations, he possessed a biological engine that, for sheer driving power and nicety of control, surpassed any other known to exist or to have ever existed on Earth—with the possible exception of the Nipe. But those five years of rebuilding and retraining had left a gap in his life.
Several of the steps required to make the conversion from man to superman had resulted in temporary insanity; the wild, swinging imbalances of glandular secretions seeking a new balance, the erratic misfirings of neurons as they attempted to adjust to higher nerve-impulse velocities, and the sheer fatigue engendered by cells that were acting too rapidly for a lagging excretory system, all had contributed to periods of greater or lesser abnormality.
That he was sane now, there was no question. But there were holes in his memory that still had to be filled.
He admitted as much to Colonel Mannheim.
"I see." The colonel rubbed one hand along the angle of his jaw, considering his next words. "Can you give me, in your own words, a general summary of the type of thing the Nipe has been doing?"
"I think so," Stanton said.
His verbal summary was succinct and accurate. The loot that the Nipe had been stealing had, at first, seemed to be a hodgepodge of everything. It was unpredictable. Money, as such, he apparently had no use for. He had taken gold, silver, and platinum, but one raid for each of these elements had evidently been enough, with the exception of silver, which had required three raids over a period of four years. Since then, he hadn't touched silver again.
He hadn't yet tried for any of the radioactives except radium. He'd taken a full ounce of that in five raids, but hadn't attempted to get his hands on uranium, thorium, plutonium, or any of the other elements normally associated with atomic energy. Nor had he tried to steal any of the fusion materials—the heavy isotopes of hydrogen or any of the lithium isotopes. Beryllium had been taken, but whether there was any significance in the thefts or not, no one knew.
There was a pattern in the thefts and robberies, nonetheless. They had begun small and had increased. Scientific and technical instruments—oscilloscopes, X-ray generators, radar equipment, maser sets, dynostatic crystals, thermolight resonators, and so on—were stolen complete or gutted for various parts. After a while, he had gone on to bigger things—whole aircraft, with their crews, had vanished.
That he had not committed anywhere near all the crimes that had been attributed to him was certain; that he had committed a great many of them was equally certain.
There was no doubt at all that his loot was being used to make instruments and devices of unknown kinds. He had used several of them on his raids. The one that could apparently phase out any electromagnetic frequency up to about a hundred thousand megacycles—including sixty-cycle power frequencies—was considered a particularly cute item. So was the gadget that reduced the tensile strength of concrete to about that of a good grade of marshmallow.
After he had been operating for a few years, there was no installation on Earth that could be considered Nipe-proof for more than a few minutes. He struck when and where he wanted and took whatever he needed.
It was manifestly impossible to guard against the Nipe, since no one knew what sort of loot might strike his fancy next, and there was therefore no way of knowing where or how he would hit next.
Nor could he ever be found after one of his raids. They were plotted and followed through with diabolical accuracy and thoroughness. He struck, looted, and vanished. And he wasn't seen again until his next strike.
Colonel Mannheim, who had carefully puffed a cigar alight and smoked it thoughtfully during Stanton's recitation, dropped the remains of the cigar into an ash receptacle. "Accurate but incomplete," he said quietly. "You must have made some guesses. I'd like to hear them."
Stanton finished the last of his coffee and glanced at Dr. Farnsworth. The biophysicist was thoughtfully looking down at his own cup, his expression unreadable.
All right, Stanton thought, he's looking for something. I'll let him have both barrels and see if I hit the target.
"I've thought about it," he admitted. He got up, went over to the coffee urn, and refilled his cup. "I've got a pet theory of my own. It's just a notion, really. I wouldn't dare reduce it to syllogistic form, because it might not hold much water, logically speaking. But the evidence seems conclusive enough to me."
He walked back to his seat. Colonel Mannheim was watching him, a look of interest on his face, but he said nothing.
"To me," Stanton said, "it seems incredible that the combined intelligence and organizational ability of the UN Government is incapable of finding anything out about one single alien, no matter how competent he may be. Somehow, somewhere, someone must have gotten a line on the Nipe. He must have a base for his operations, and someone should have found it by this time.
"I may be faster and stronger and more sensitive than any other living human being, but that doesn't mean I have superhuman powers, or that I'm a magician. And I'm quite certain that you, Colonel, don't credit me with such abilities. You don't believe that I can do in a short time what the combined forces of the Government couldn't do in ten. Certainly you wouldn't rely too heavily on
