be. Take a little longer to find that out, the report said.

It made Pell think of the corny sign World Government officials always had on their desks, the one about doing the difficult right away and taking a little longer for the impossible. Some day, when he was a big-shot, he would have a sign on his desk saying: Why make things difficult when with even less effort you can make them impossible? Of course, ideas like that were probably the very reason he'd never be a big-shot....

The Identifier humming. Someone coming again.

He looked up, and then had the curious feeling of being jerked back in time to several nights ago. Chief Larkin and Theodor Rysland entered.

"Hello, Dick," said Larkin, with a touch of studied democracy. He glanced at the government adviser as if to say: See? Knew we'd find him here.

Pell made a sour face. "Some day I'm going to stop giving all this free overtime. Some day I'm not going to show up at all."

Rysland smiled, dislodging some of the rock strata of his curiously pale face. He seemed a little weary this evening. He moved slowly and with even more than his usual dignity. He said, "I hope, Mr. Pell, that you'll wait at least until you finish this job for us. I understand you've made some progress."

Pell shrugged and gestured at the lab report. "Progress, maybe—but I don't know how far. Just a bunch of new puzzles to be perfectly frank."

Rysland sat down at the other desk and drummed on it with his fingertips. He looked at Pell gravely. "As a matter of fact, since we last talked to you the situation has become even more urgent. A Supremist congressman introduced a bill today before the world delegates which may prove very dangerous. Perhaps you know the one I refer to."

"I was too busy to follow the news today," said Pell, looking meaningfully at Larkin.

Larkin didn't seem to notice.

Rysland said, "I'll brief you then. The bill purports to prohibit material aid of any kind to a non-Terran government. That means both credit and goods. And since the only real non-Terran government we know is Venus, it's obviously directed specifically at the Venusians."

Pell thought it over. High level stuff again. He nodded to show he followed.

"On the surface," continued Rysland, "this would seem to be a sort of anti-espionage bill. Actually, it's a deliberately provocative act. I know the Venusians will take it that way. But right now certain quarters are secretly trying to negotiate a trade treaty with Venus which would be a major step toward peaceful relations. If this bill became law, such a treaty would be impossible."

"But World Congress isn't likely to pass such a bill, is it? Won't they see through it?"

Rysland frowned. "That's what we're not sure of. Messages are pouring in urging passage—all of them from Supremists, of course. The Supremists are relatively few, but they make a lot of noise. Sometimes noise like that is effective. It could swing a lot of delegates who don't see the real danger of this bill and are at the moment undecided. The Defender side, with its desire to isolate and fortify, is especially susceptible."

"That is bad," said Pell thoughtfully.

Rysland put his palm on the desk. "Now then, if we can somehow discredit the Supremists—get to the bottom of this thing quickly enough—I'm sure that bill will be killed. I came here tonight, I suppose, out of pure anxiety. In other words, Mr. Pell, just how far are you?"

Pell smiled and shook his head. "Not very, I'm afraid. This Supremist thing is the damndest I ever came across. No central headquarters, no officers, no propaganda mill—entirely word of mouth as far as I can see. No way of finding out how it started, or even how the new members are proselyted. Ask any member how he became a Supremist. He just looks kind of dreamy and mutters something about the truth suddenly dawning upon him one day."

"But don't you have any theories?"

"I've got a hunch," Pell said, picking up the lab report.

Chief Larkin snorted softly. The snort said clearly enough that an efficient investigator didn't depend on hunches these days: he went after something doggedly on the computer, or by other approved techniques.

Pell pretended not to hear the snort. "First of all we discovered that nearly all Supremists received some kind of an inoculation before they became Supremists. Then we found a whole village, one of those moon resort towns, that had gone over. There was the record of inoculation there, too. I got hold of some of the vaccine and had the lab analyze it. It's mostly vaccine all right, but there is a foreign substance in it. Listen." He read from the report: "Isolated point oh six four seven grams unclassified crystal compound, apparently form of nucleotide enzyme. Further analysis necessary."

"You think this enzyme, or whatever it is, has something to do with it?"

"I don't know. All I have is a pretty wild theory. To begin, when our lab can't analyze something right away, it's pretty rare—possibly even unknown to chemistry in general. Now it's just possible that this substance does something to the brain that makes a man into a Supremist, and that somebody's behind the whole thing, deliberately planting the stuff so that people here and there become injected with it."

"Pell." Larkin made a pained face. "Really."

Pell shrugged. "Well, as I say, it's a hunch, that's all."

"It's a pipe dream," said Larkin. "I never heard of anything so fantastic."

"That's what folks said a couple of centuries ago when the Venusians were first trying to make contact and their ships were sighted all over the place. 'I never heard of anything so fantastic,' they all said."

Theodor Rysland still looked interested. "Granted there is some connection between the Supremist mental state and this, er, enzyme. What then, Mr. Pell?"

"Well," said Pell, stretching his legs out, "I had an idea maybe your friend Dr. Nebel could give us some help on that."

"Nebel?"

"He's interested in this thing, isn't he?"

"Definitely. Nebel's a very public spirited man."

"Well, I understand he's one of the top psychobiologists in the country today. Seems to me this new enzyme, whatever it is, would be right up his alley. Of course the lab should get to it eventually, but he might do it a lot quicker."

Larkin had been examining some statistical crime charts on the wall. He turned from them. "Pell, does Kronski know about all these wild hunches of yours?"

"I haven't talked with him about them yet. He left today before the lab report came in. Why?"

"I was just wondering," said Larkin evenly, "whether I had two maniacs in my organization or only one."

Rysland, frowning, turned to the chief. "I wouldn't be hasty, Larkin," he said. "Crazy as it sounds Pell may have something here."

Larkin snorted again, and this time along with it he shook his head sadly.

"What's your next move then?" Rysland asked Pell.

"Tomorrow morning, first thing," Pell said, "I'll take a sample of this stuff to Dr. Nebel and see what he can do with it. Of course the lab can keep on working on it in the meantime."

"Don't you think you might do better to get busy on those computers?" Larkin asked.

Pell shook his head. "This hunch is too strong, Chief."

Rysland smiled, and got up. "I'm inclined to put a little stock into this man's hunches. He's done pretty well with them so far. I'd even say he's pretty close to a solution of this thing—possibly."

Larkin shrugged and started to look at the crime charts again.

Rysland held out his hand. "Good night, Mr. Pell. You've encouraged me. Larkin and I are going topside for a little night cap before we turn in. Like to join us?"

"No, thanks," said Pell. "I'm sleepy. I want to get home and hit that sack."

"Very well. Good night again." The two men went toward the door.

Pell watched them quietly. He had lied. He
