"Pathological liar," murmured Blue. The words were barely audible, but the gnarly man heard them.

"You're ent.i.tled to your opinion, Dr. Blue," he said affably. "Dr. Saddler's doing me a favor, so in return I'm letting you all shoot questions at me. And I'm answering. I don't give a d.a.m.n whether you believe me or not."

MeGannon hastily threw in another question. "How is it that you have a birth certificate, as you say you have?"

"Oh, I knew a man named Clarence Gaffney once. He got killed by an automobile, and I took his name."

"Was there any reason for picking this Irish background?"

"Are you Irish, Dr. McGannon?"

"Not enough to matter."

"Okay. I didn't want to hurt any feelings. It's my best bet. There are real Irishmen with upper lips like mine."

Dr. Saddler broke in. "I meant to ask you, Clarence." She put a lot of warmth into his name. "There's an argument as to whether your people interbred with mine, when mine overran Europe at the end of the Mousterian. It's been thought that the 'old black breed' of the west coast of Ireland might have a little Neanderthal blood."

He grinned slightly. "Well-yes and no. There never was any back in the Stone Age, as far as I know. But these long-lipped Irish are my fault."

"How?"

"Believe it or not, but in the last fifty centuries there have been some women of your species that didn't find me too repulsive. Usually there were no offspring. But in the Sixteenth Century I went to Ireland to live. They were burning too many people for witchcraft in the rest of Europe to suit me at that time. And there was a woman. The result this time was a flock of hybrids-cute little devils they were. So the 'old black breed' are my descendants."

"What did happen to your people?" asked McGannon. 'Were they killed off?"

The gnarly man shrugged. "Some of them. We weren't at all warlike. But then the tall ones, as we called them, weren't either. Some of the tribes of the tall ones looked on us as legitimate prey, but most of them let us severely alone. I guess they were almost as scared of us as we were of them. Savages as primitive as that are really pretty peaceable people. You have to work so hard, and there are so few of you, that there's no object in fighting wars. That comes later, when you get agriculture and livestock, so you have something worth stealing.

"I remember that a hundred years after the tall ones had come, there were still Neanderthalers living in my part of the country. But they died out. I think it was that they lost their ambition. The tall ones were pretty crude, but they were so far ahead of us that our things and our customs seemed silly. Finally we just sat around and lived on what sc.r.a.ps we could beg from the tall ones' camps. You might say we died of an inferiority complex."

"What happened to you?" asked McGannon.

"Oh, I was a G.o.d among my own people by then, and naturally I represented them in dealings with the tall ones. I got to know the tall ones pretty well, and they were willing to put up with me after all my own clan were dead. Then in a couple of hundred years they'd forgotten all about my people, and took me for a hunchback or something. I got to - be pretty good at flintworking, so I could earn my keep. When metal came in I went into that, and finally into blacksmithing. If you put all the horseshoes I've made in a pile, they'd-well, you'd have a d.a.m.n big pile of horseshoes anyway."

"Did you limp at that time?" asked McGannon.

"Uk-huh. I busted my leg back in the Neolithic. Fell out of a tree, and had to set it myself, because there wasn't anybody around. Why?"

"Vulcan," said McGannon softly.

"Vulcan?" repeated the gnarly man. "Wasn't he a Greek G.o.d or something?"

"Yes. He was the lame blacksmith of the G.o.ds."

"You mean you think that maybe somebody got the idea from me? That's an interesting idea. Little late to check up on it, though." Blue leaned forward, and said crisply, "Mr. Gaffney, no real Neanderthal man could talk as entertainingly as you do. That's shown by the poor development of the frontal lobes of the brain and the attachments of the tongue muscles."

The gnarly man shrugged again. "You can believe what you like. My own clan considered me pretty smart, and then you're bound to learn something in fifty thousand years."

Dr. Saddler said, "Tell them about your teeth, Clarence."

The gnarly man grinned. "They're false, of course. My own lasted a long time, but they still wore out somewhere back in the Paleolithic. I grew a third set, and they wore out too. So I had to invent soup."

"You what?" It was the usually taciturn Jeff cott.

"I had to invent soup, to keep alive. You know, the bark-dish-andhot-stones method. My gums got pretty tough after a while, but they still weren't much good for chewing hard stuff. So after a few thousand years I got pretty sick of soup and mushy foods generally. And when metal came in I began experimenting with false teeth. I finally made some pretty good ones. Amber teeth in copper plates. You might say I invented them too. I tried often to sell them, but they never really caught on until around 1750 A.D. I was living in Paris then, and I built up quite a little business before I moved on." He pulled the handkerchief out of his breast pocket to wipe his forehead; Blue made a face as the wave of perfume reached him.

"Well, Mr. Caveman," snapped Blue sarcastically, "how do you like our machine age?"

The gnarly man ignored the tone of the question. "It's not bad. Lots of interesting things happen. The main trouble is the shirts."

"Shirts?"

"Uh-huh. Just try to buy a shirt with a 20 neck and a 29 sleeve. I have to order 'em special. It's almost as bad with hats and shoes. I wear an 8-1/2 and a 13 shoe." He looked at his watch. "I've got to get back to Coney to work."

McGannon jumped up. "Where can I get in touch with you again, Mr. Gaffney? There's lots of things I'd like to ask you."

The gnarly man told him. "I'm free mornings. My working hours are two to midnight on weekdays, with a couple of hours off for dinner. Union rules, you know."

"You mean there's a union for you show people?"

"Sure. Only they call it a guild. They think they're artists, you know."

Blue and Jeffcott watched the gnarly man and the historian walking slowly toward the subway together. Blue said, "Poor old Mac! I always thought he had sense. Looks like he's swallowed this Gaffney's ravings hook, line, and sinker."

"I'm not so sure," said Jeff cott, frowning. "There's something funny about the business."

"What?" barked Blue. "Don't tell me that you believe this story of being alive fifty thousand years? A caveman who uses perfume? Good G.o.d!"

"N-no," said Jeffcott. "Not the fifty thousand part. But I don't think it's a simple case of paranoia or plain lying either. And the perfume's quite logical, if he were telling the truth."

"Huh?"

"Body odor. Saddler told us how dogs hate him. He'd have a smell different from ours. We're so used to ours that we don't even know we have one, unless somebody goes without a bath for a couple of months. But we might notice his if he didn't disguise it."

Blue snorted. "You'll be believing him yourself in a minute. It's an obvious glandular case, and he's made up this story to fit. All that talk about not caring whether we believe him or not is just bluff. Come on, let's get some lunch. Say, did you see the way Saddler looked at him every time she said 'Clarence'? Wonder what she thinks she's going to do with him?"

Jeffcott thought. "I can guess. And if he is telling the truth, I think there's something in Deuteronomy against it"

The great surgeon made a point of looking like a great surgeon, to pince-nez and Vand.y.k.e. He waved the X-ray negatives at the gnarly man, pointing out this and that.

"We'd better take the leg first," he said. "Suppose we do that next Tuesday. When you've recovered from that we can tackle the shoulder."

The gnarly man agreed, and shuffled out of the little private hospital to where McGannon awaited him in his car. The gnarly man described the tentative schedule of operations, and mentioned that he had made arrangements to quit his job at the last minute. "Those two are the main things," he said. "I'd like to try professional wres thug again some day, and I can't unless I get this shoulder fixed so I can raise my left arm over my head."

"What happened to it?" asked McGannon.

The gnarly man closed his eyes, thinking. "Let me see. I get things mixed up sometimes. People do when they're only fifty years old, so you can imagine what it's like for me.

"In 42 B.C. I was living with the Bituriges in Gaul. You remember that Caesar shut up Werkinghetorich-Vercingetorix to you-in Alesia, and the confederacy raised an army of relief under Caswallon."

"Caswallon?"

The gnarly man laughed shortly. "I meant Wercaswallon. Caswahlon was a Briton, wasn't he? I'm always getting those two mixed up.

"Anyhow, I got drafted. That's all you can call it; I didn't want to go. It wasn't exactly my war. But they wanted me because I could pull twice as heavy a bow as anybody else.

"When the final attack on Caesar's ring of fortifications came, they sent me forward with some other archers to provide a covering fire for their infantry. At least that was the plan. Actually I never saw such a hopeless muddle in my life. And before I even got within bow-shot, I fell into one of the Romans' covered pits. I didn't land on the point of the stake, but I fetched up against the side of it and busted my shoulder. There wasn't any help, because the Gauls were too busy running away from Caesar's German cavalry to bother about wounded men."

The author of G.o.d, Man, and the Universe gazed after his departing patient. He spoke to his head a.s.sistant. "What do you think of him?"

"I think it's so," said the a.s.sistant. "I looked over those X-rays pretty closely. That skeleton never belonged to a human being."

"Hmm. Hmm," said Dunbar. "That's right, he wouldn't be human, would he? Hmm. You know, if anything happened to him-"

The a.s.sistant grinned understandingly. "Of course there's the S.P.C.A.".

"We needn't worry about them. Hmm." He thought, you've been slipping: nothing big in the papers for a year. But if you published a complete anatomical description of a Neanderthal man-or if you found out why his medulla functions the way it does-hmm-of course it would have to be managed properly- "Let's have lunch at the Natural History Museum," said MeGannon. "Some of the people there ought to know you."

"Okay," drawled the gnarhy man. "Only I've still got to get back to Coney afterward. This is my last day. Tomorrow Pappas and I are going up to see our lawyer about ending our contract. It's a dirty trick on poor old John, but I warned him at the start that this might happen."

"I suppose we can come up to interview you while you're-ah- convalescing? Fine. Have you ever been to the Museum, by the way?"

"Sure," said the gnarly man. "I get around."

"What did you-ah-think of their stuff in the Hall of the Age of Man?"

"Pretty good. There's a little mistake in one of those big wall paintings. The second horn on the woolly rhinoceros ought to slant forward more. I thought about writing them a letter. But you know how it is. They say 'Were you there?' and I say 'Uh-huh' and they say 'Another nut."

"How about the pictures and busts of Paleohithic men?"

"Pretty good. But they have some funny ideas. They always show us with skins wrapped around our middles. In summer we didn't wear skins, and in winter we hung them around our shoulders where they'd do some good.

"And then they show those tall ones that you call Cro-Magnon men clean shaven. As I remember they all had whiskers. What would they shave with?"

"I think," said McGannon, "that they leave the beards off the busts to-ah-show the shape of the chins. With the beards they'd all look too much alike."

"Is that the reason? They might say so on the labels." The gnarly man rubbed his own chin, such as it was. "I wish beards would come back into style. I look much more human with a beard. I got along fine in the Sixteenth Century when everybody had whiskers.

"That's one of the ways I remember when things happened, by the haircuts and whiskers that people had. I remember when a wagon I was driving in Milan lost a wheel and spilled flour bags from h.e.l.l to breakfast. That must have been in the Sixteenth Century, before I went to Ireland, because I remember that most of the men in the crowd that collected had beards. Now-wait a minute- maybe that was the Fourteenth. There were a lot of beards then too."

"Why, why didn't you keep a diary?" asked McGannon with a groan of exasperation.

The gnarly man shrugged characteristically. aAnd pack around six trunks full of paper every time I moved? No, thanks."

"I-ah-don't suppose you could give me the real story of Richard III and the princes in the Tower?"

"Why should I? I was just a poor blacksmith or farmer or something most of the time. I didn't go around with the big shots. I gave up all my ideas of ambition a long time before that. I had to, being so different from other people. As far as I can remember, the only real king I ever got a good look at was Charlemagne, when he made a speech in Paris one day. He was just a big tall man with Santa Claus whiskers and a squeaky voice."

Next morning McGannon and the gnarly man had a session with Svedberg at the Museum, after which McGannon drove Gaffney around to the lawyer's office, on the third floor of a seedy old office building in the West Fifties. James Robinette looked something like a movie actor and something like a chipmunk. He glanced at his watch and said to McGannon: "This won't take long. If you'd like to stick around I'd be glad to have lunch with you." The fact was that he was feeling just a trifle queasy about being left with this d.a.m.n queer client, this circus freak or whatever he was, with his barrel body and his funny slow drawl.

When the business had been completed, and the gnarly man had gone off with his manager to wind up his affairs at Coney, Robinette said, "Whew! I thought he was a halfwit, from his looks. But there was nothing halfwitted about the way he went over those clauses. You'd have thought the d.a.m.n contract was for building a subway system. What is he, anyhow?"

McGannon told him what he knew.

The lawyer's eyebrows went up. "Do you believe his yarn?"

"I do. So does Saddler. So does Svedberg up at the Museum. They're both topnotchers in their respective fields. Saddler and I have interviewed him, and Svedberg's examined him physically. But it's just opinion. Fred Blue still swears it's a hoax or a case of some sort of dementia. Neither of us can prove anything."

"Why not?"

"Well-ah-how are you going to prove that he was or was not alive a hundred years ago? Take one case: Clarence says he ran a sawmill in Fairbanks, Alaska, in 1906 and '07, under the name of Michael Shawn. How are you going to find out whether there was a sawmill operator in Fairbanks at that time? And if you did stumble on a record of a Michael Shawn, how would you know whether he and Clarence were the same? There's not a chance in a thousand that there'd be a photograph or a detailed description you could check with. And you'd have an awful time trying to find anybody who remembered him at this late date.

"Then, Svedberg poked around Clarence's face, and said that no human being ever had a pair of zygomatic arches like that. But when I told Blue that, he offered to produce photographs of a human skull that did. I know what'll happen: Blue will say that the arches are practically the same, and Svedberg will say that they're obviously different. So there we'll be."

Robinette mused, "He does seem d.a.m.ned intelligent for an apeman."

"He's not an ape-man really. The Neanderthal race was a separate branch of the human stock; they were more primitive in some ways and more advanced in others than we are. Clarence may be slow, but he usually grinds out the right answer. I imagine that he was-ah- brilliant, for one of his kind, to begin with. And he's had the benefit of so much experience. He knows us; he sees through us and our motives." The little pink man puckered up his forehead. "I do hope nothing happens to him. He's carrying around a lot of priceless information in that big -head of his. Simply priceless. Not much about war and politics; he kept clear of those as a matter of self-preservation. But little things, about how people lived and how they thought thousands of years ago. He gets his periods mixed up sometimes, but he gets them straightened out if you give him time.

"I'll have to get hold of Pell, the linguist. Clarence knows dozens of ancient languages, such as Gothic and Gaulish. I was able to check him on some of them, like vulgar Latin; that was one of the things that convinced me. And there are archeologists and psychologists. . .

"If only something doesn't happen to scare him off. We'd never find him. I don't know. Between a man-crazy female scientist and a publicity-mad surgeon-I wonder how it'll work out."

The gnarly man innocently entered the waiting room of Dunbar's hospital. He as usual spotted the most comfortable chair and settled luxuriously into it.

Dunbar stood before him. His keen eyes gleamed with antic.i.p.ation behind their pince-nez. "There'll be a wait of about half an hour, Mr. Gaffney," he said. "We're all tied up now, you know. I'll send Mahler in; he'll see that you have anything you want." Dunbar's eyes ran lovingly over the gnarly man's stumpy frame. What fascinating secrets mightn't he discover once he got inside it?

Mahler appeared, a healthy-looking youngster. Was there anything Mr. Gaffney would like? The gnarly man paused as usual to let his ma.s.sive mental machinery grind. A vagrant impulse moved him to ask to see the instruments that were to be used on him.

Mahler had his orders, but this seemed a harmless enough request. lie went and returned with a tray full of gleaming steel. "You see," he said, "these are called scalpels."

Presently the gnarly man asked, "What's this?" He picked up a peculiar-looking instrument. - "Oh, that's the boss's own invention. For getting at the midbrain."

"Midbrain? What's that doing here?"

"Why, that's for getting at your-that must be there by mistake-" Little lines tightened around the queer hazel eyes. "Yeah?" He remembered the look Dunbar had given him, and Dunbar's general reputation. "Say, could I use your phone a minute?"

"Why-I suppose-what do you want to phone for?"

"I want to call my lawyer. Any objections?"

"No, of course not. But there isn't any phone here."
