THE EDGE

Chalmers stopped talking abruptly, warned by the sudden attentiveness

of the class in front of him. They were all staring; even Guellick, in

the fourth row, was almost half awake. Then one of them, taking his

silence as an invitation to questions found his voice.

"You say Khalid ib'n Hussein's been assassinated?" he asked

incredulously. "When did that happen?"

[Illustration: There was no past--no future--only a great chaotic

NOW.]

"In 1973, at Basra." There was a touch of impatience in his voice;

surely they ought to know that much. "He was shot, while leaving the

Parliament Building, by an Egyptian Arab named Mohammed Noureed,

with an old U. S. Army M3 submachine-gun. Noureed killed two of

Khalid's guards and wounded another before he was overpowered. He was

lynched on the spot by the crowd; stoned to death. Ostensibly, he and

his accomplices were religious fanatics; however, there can be no

doubt whatever that the murder was inspired, at least indirectly, by

the Eastern Axis."

The class stirred like a grain-field in the wind. Some looked at him

in blank amazement; some were hastily averting faces red with poorly

suppressed laughter. For a moment he was puzzled, and then realization

hit him like a blow in the stomach-pit. He'd forgotten, again.

"I didn't see anything in the papers about it," one boy was saying.

"The newscast, last evening, said Khalid was in Ankara, talking to the

President of Turkey," another offered.

"Professor Chalmers, would you tell us just what effect Khalid's death

had upon the Islamic Caliphate and the Middle Eastern situation in

general?" a third voice asked with exaggerated solemnity. That was

Kendrick, the class humorist; the question was pure baiting.

"Well, Mr. Kendrick, I'm afraid it's a little too early to assess the

full results of a thing like that, if they can ever be fully assessed.

For instance, who, in 1911, could have predicted all the consequences

of the pistol-shot at Sarajevo? Who, even today, can guess what the

history of the world would have been had Zangarra not missed Franklin

Roosevelt in 1932? There's always that if."

He went on talking safe generalities as he glanced covertly at his

watch. Only five minutes to the end of the period; thank heaven he

hadn't made that slip at the beginning of the class. "For instance,

tomorrow, when we take up the events in India from the First World War

to the end of British rule, we will be largely concerned with another

victim of the assassin's bullet, Mohandas K. Gandhi. You may ask

yourselves, then, by how much that bullet altered the history of the

Indian sub-continent. A word of warning, however: The events we will

be discussing will be either contemporary with or prior to what was

discussed today. I hope that you're all keeping your notes properly

dated. It's always easy to become confused in matters of chronology."

He wished, too late, that he hadn't said that. It pointed up the very

thing he was trying to play down, and raised a general laugh.

As soon as the room was empty, he hastened to his desk, snatched

pencil and notepad. This had been a bad one, the worst yet; he hadn't

heard the end of it by any means. He couldn't waste thought on that

now, though. This was all new and important; it had welled up suddenly

and without warning into his conscious mind, and he must get it down

in notes before the "memory"--even mentally, he always put that word

into quotes--was lost. He was still scribbling furiously when the

instructor who would use the room for the next period entered,

followed by a few of his students. Chalmers finished, crammed the

notes into his pocket, and went out into the hall.

Most of his own Modern History IV class had left the building and were

on their way across the campus for science classes. A few, however,

were joining groups for other classes here in Prescott Hall, and in

every group, they were the center of interest. Sometimes, when they

saw him, they would fall silent until he had passed; sometimes they

didn't, and he caught snatches of conversation.

"Oh, brother! Did Chalmers really blow his jets this time!" one voice

was saying.

"Bet he won't be around next year."

Another quartet, with their heads together, were talking more

seriously.

"Well, I'm not majoring in History, myself, but I think it's an

outrage that some people's diplomas are going to depend on grades

given by a lunatic!"

"Mine will, and I'm not going to stand for it. My old man's president

of the Alumni Association, and...."

* * * * *

That was something he had not thought of, before. It gave him an ugly

start. He was still thinking about it as he turned into the side hall

to the History Department offices and entered the cubicle he shared

with a colleague. The colleague, old Pottgeiter, Medieval History, was

emerging in a rush; short, rotund, gray-bearded, his arms full of

books and papers, oblivious, as usual, to anything that had happened

since the Battle of Bosworth or the Fall of Constantinople. Chalmers

stepped quickly out of his way and entered behind him. Marjorie

Fenner, the secretary they also shared, was tidying up the old man's

desk.

"Good morning, Doctor Chalmers." She looked at him keenly for a

moment. "They give you a bad time again in Modern Four?"

Good Lord, did he show it that plainly? In any case, it was no use

trying to kid Marjorie. She'd hear the whole story before the end of

the day.

"Gave myself a bad time."

Marjorie, still fussing with Pottgeiter's desk, was about to say

something in reply. Instead, she exclaimed in exasperation.

"Ohhh! That man! He's forgotten his notes again!" She gathered some

papers from Pottgeiter's desk, rushing across the room and out the

door with them.

For a while, he sat motionless, the books and notes for General

European History II untouched in front of him. This was going to raise

hell. It hadn't been the first slip he'd made, either; that thought

kept recurring to him. There had been the time when he had alluded to

the colonies on Mars and Venus. There had been the time he'd mentioned

the secession of Canada from the British Commonwealth, and the time

he'd called the U. N. the Terran Federation. And the time he'd tried

to get a copy of Franchard's _Rise and Decline of the System States_,

which wouldn't be published until the Twenty-eighth Century, out of

the college library. None of those had drawn much comment, beyond a

few student jokes about the history professor who lived in the future

instead of the past. Now, however, they'd all be remembered, raked up,

exaggerated, and added to what had happened this morning.

He sighed and sat down at Marjorie's typewriter and began transcribing

his notes. Assassination of Khalid ib'n Hussein, the pro-Western

leader of the newly formed Islamic Caliphate; period of anarchy in the

Middle East; interfactional power-struggles; Turkish intervention. He

wondered how long that would last; Khalid's son, Tallal ib'n Khalid,

was at school in England when his father was--would be--killed. He

would return, and eventually take his father's place, in time to bring

the Caliphate into the Terran Federation when the general war came.

There were some notes on that already; the war would result from an

attempt by the Indian Communists to seize East Pakistan. The trouble

was that he so seldom "remembered" an exact date. His "memory" of the

year of Khalid's assassination was an exception.

Nineteen seventy-three--why, that was this year. He looked at the

calendar. October 16, 1973. At very most, the Arab statesman had two

and a half months to live. Would there be any possible way in which he

could give a credible warning? He doubted it. Even if there were, he

questioned whether he should--for that matter, whether he

_could_--interfere....

* * * * *

He always lunched at the Faculty Club; today was no time to call

attention to himself by breaking an established routine. As he

entered, trying to avoid either a furtive slink or a chip-on-shoulder

swagger, the crowd in the lobby stopped talking abruptly, then began

again on an obviously changed subject. The word had gotten around,

apparently. Handley, the head of the Latin Department, greeted him

with a distantly polite nod. Pompous old owl; regarded himself, for

some reason, as a sort of unofficial Dean of the Faculty. Probably

didn't want to be seen fraternizing with controversial characters.

One of the younger men, with a thin face and a mop of unruly hair,

advanced to meet him as he came in, as cordial as Handley was remote.

"Oh, hello, Ed!" he greeted, clapping a hand on Chalmers' shoulder. "I

was hoping I'd run into you. Can you have dinner with us this

evening?" He was sincere.

"Well, thanks, Leonard. I'd like to, but I have a lot of work. Could

you give me a rain-check?"

"Oh, surely. My wife was wishing you'd come around, but I know how it

is. Some other evening?"

"Yes, indeed." He guided Fitch toward the dining-room door and nodded

toward a table. "This doesn't look too crowded; let's sit here."

After lunch, he stopped in at his office. Marjorie Fenner was there,

taking dictation from Pottgeiter; she nodded to him as he entered, but

she had no summons to the president's office.

* * * * *

The summons was waiting for him, the next morning, when he entered the

office after Modern History IV, a few minutes past ten.

"Doctor Whitburn just phoned," Marjorie said. "He'd like to see you,

as soon as you have a vacant period."

"Which means right away. I shan't keep him waiting."

She started to say something, swallowed it, and then asked if he

needed anything typed up for General European II.

"No, I have everything ready." He pocketed the pipe he had filled on

entering, and went out.

* * * * *

The president of Blanley College sat hunched forward at his desk; he

had rounded shoulders and round, pudgy fists and a round, bald head.

He seemed to be expecting his visitor to stand at attention in front

of him. Chalmers got the pipe out of his pocket, sat down in the

desk-side chair, and snapped his lighter.

"Good morning, Doctor Whitburn," he said very pleasantly.

Whitburn's scowl deepened. "I hope I don't have to tell you why I

wanted to see you," he began.

"I have an idea." Chalmers puffed until the pipe was drawing

satisfactorily. "It might help you get started if you did, though."

"I don't suppose, at that, that you realize the full effect of your

performance, yesterday morning, in Modern History Four," Whitburn

replied. "I don't suppose you know, for instance, that I had to

intervene at the last moment and suppress an editorial in the _Black

and Green_, derisively critical of you and your teaching methods, and,

by implication, of the administration of this college. You didn't hear

about that, did you? No, living as you do in the future, you

wouldn't."

"If the students who edit the _Black and Green_ are dissatisfied with

anything here, I'd imagine they ought to say so," Chalmers commented.

"Isn't that what they teach in the journalism classes, that the

purpose of journalism is to speak for the dissatisfied? Why make

exception?"

"I should think you'd be grateful to me for trying to keep your

behavior from being made a subject of public ridicule among your

students. Why, this editorial which I suppressed actually went so far

as to question your sanity!"

"I should suppose it might have sounded a good deal like that, to

them. Of course, I have been preoccupied, lately, with an imaginative

projection of present trends into the future. I'll quite freely admit

that I should have kept my extracurricular work separate from my

class and lecture work, but...."

"That's no excuse, even if I were sure it were true! What you did,

while engaged in the serious teaching of history, was to indulge in a

farrago of nonsense, obvious as such to any child, and damage not only

your own standing with your class but the standing of Blanley College

as well. Doctor Chalmers, if this were the first incident of the kind

it would be bad enough, but it isn't. You've done things like this

before, and I've warned you before. I assumed, then, that you were

merely showing the effects of overwork, and I offered you a vacation,

which you refused to take. Well, this is the limit. I'm compelled to

request your immediate resignation."

Chalmers laughed. "A moment ago, you accused me of living in the

future. It seems you're living in the past. Evidently you haven't

heard about the Higher Education Faculty Tenure Act of 1963, or such

things as tenure-contracts. Well, for your information, I have one;

you signed it yourself, in case you've forgotten. If you want my

resignation, you'll have to show cause, in a court of law, why my

contract should be voided, and I don't think a slip of the tongue is

a reason for voiding a contract that any court would accept."

Whitburn's face reddened. "You don't, don't you? Well, maybe it isn't,

but insanity is. It's a very good reason for voiding a contract

voidable on grounds of unfitness or incapacity to teach."

He had been expecting, and mentally shrinking from, just that. Now

that it was out, however, he felt relieved. He gave another short

laugh.

"You're willing to go into open court, covered by reporters from

papers you can't control as you do this student sheet here, and

testify that for the past twelve years you've had an insane professor

on your faculty?"

"You're.... You're trying to blackmail me?" Whitburn demanded, half

rising.

"It isn't blackmail to tell a man that a bomb he's going to throw will

blow up in his hand." Chalmers glanced quickly at his watch. "Now,

Doctor Whitburn, if you have nothing further to discuss, I have a

class in a few minutes. If you'll excuse me...."

He rose. For a moment, he stood facing Whitburn; when the college

president said nothing, he inclined his head politely and turned,

going out.

Whitburn's secretary gave the impression of having seated herself

hastily at her desk the second before he opened the door. She watched

him, round-eyed, as he went out into the hall.

He reached his own office ten minutes before time for the next class.

Marjorie was typing something for Pottgeiter; he merely nodded to her,

and picked up the phone. The call would have to go through the school

exchange, and he had a suspicion that Whitburn kept a check on outside

calls. That might not hurt any, he thought, dialing a number.

"Attorney Weill's office," the girl who answered said.

"Edward Chalmers. Is Mr. Weill in?"

She'd find out. He was; he answered in a few seconds.

"Hello, Stanly; Ed Chalmers. I think I'm going to need a little help.

I'm having some trouble with President Whitburn, here at the college.

A matter involving the validity of my tenure-contract. I don't want to

go into it over this line. Have you anything on for lunch?"

"No, I haven't. When and where?" the lawyer asked.

He thought for a moment. Nowhere too close the campus, but not too far

away.

"How about the Continental; Fontainbleu Room? Say twelve-fifteen."

"That'll be all right. Be seeing you."

Marjorie looked at him curiously as he gathered up the things he

needed for the next class.

* * * * *

Stanly Weill had a thin dark-eyed face. He was frowning as he set down

his coffee-cup.

"Ed, you ought to know better than to try to kid your lawyer," he

said. "You say Whitburn's trying to force you to resign. With your

contract, he can't do that, not without good and sufficient cause, and

under the Faculty Tenure Law, that means something just an inch short

of murder in the first degree. Now, what's Whitburn got on you?"

Beat around the bush and try to build a background, or come out with

it at once and fill in the details afterward? He debated mentally for

a moment, then decided upon the latter course.

"Well, it happens that I have the ability to prehend future events. I

can, by concentrating, bring into my mind the history of the world, at

least in general outline, for the next five thousand years. Whitburn

thinks I'm crazy, mainly because I get confused at times and forget

that something I know about hasn't happened yet."

Weill snatched the cigarette from his mouth to keep from swallowing

it. As it was, he choked on a mouthful of smoke and coughed violently,

then sat back in the booth-seat, staring speechlessly.

"It started a little over three years ago," Chalmers continued. "Just

after New Year's, 1970. I was getting up a series of seminars for some

of my postgraduate students on extrapolation of present social and

political trends to the middle of the next century, and I began to

find that I was getting some very fixed and definite ideas of what the

world of 2050 to 2070 would be like. Completely unified world,

abolition of all national states under a single world sovereignty,

colonies on Mars and Venus, that sort of thing. Some of these ideas

didn't seem quite logical; a number of them were complete reversals of

present trends, and a lot seemed to depend on arbitrary and

unpredictable factors. Mind, this was before the first rocket landed

on the Moon, when the whole moon-rocket and lunar-base project was a

triple-top secret. But I knew, in the spring of 1970, that the first

unmanned rocket would be called the _Kilroy_, and that it would be

launched some time in 1971. You remember, when the news was released,

it was stated that the rocket hadn't been christened until the day

before it was launched, when somebody remembered that old

'Kilroy-was-here' thing from the Second World War. Well, I knew about

it over a year in advance."

Weill had been listening in silence. He had a naturally skeptical

face; his present expression mightn't really mean that he didn't

believe what he was hearing.

"How'd you get all this stuff? In dreams?"

Chalmers shook his head. "It just came to me. I'd be sitting reading,

or eating dinner, or talking to one of my classes, and the first thing

I'd know, something out of the future would come bubbling up in me. It

just kept pushing up into my conscious mind. I wouldn't have an idea

of something one minute, and the next it would just be part of my

general historical knowledge; I'd know it as positively as I know that

Columbus discovered America in. 1492. The only difference is that I

can usually remember where I've read something in past history, but my

future history I know without knowing how I know it."

"Ah, that's the question!" Weill pounced. "You don't know how you know

it. Look, Ed, we've both studied psychology, elementary psychology at

least. Anybody who has to work with people, these days, has to know

some psychology. What makes you sure that these prophetic impressions

of yours aren't manufactured in your own subconscious mind?"

"That's what I thought, at first. I thought my subconscious was just

building up this stuff to fill the gaps in what I'd produced from

logical extrapolation. I've always been a stickler for detail," he

added, parenthetically. "It would be natural for me to supply details

for the future. But, as I said, a lot of this stuff is based on

unpredictable and arbitrary factors that can't be inferred from

anything in the present. That left me with the alternatives of

delusion or precognition, and if I ever came near going crazy, it was

before the _Kilroy_ landed and the news was released. After that, I

knew which it was."

"And yet, you can't explain how you can have real knowledge of a

thing before it happens. Before it exists," Weill said.

"I really don't need to. I'm satisfied with knowing that I know. But

if you want me to furnish a theory, let's say that all these things

really do exist, in the past or in the future, and that the present is

just a moving knife-edge that separates the two. You can't even

indicate the present. By the time you make up your mind to say, 'Now!'

and transmit the impulse to your vocal organs, and utter the word, the

original present moment is part of the past. The knife-edge has gone

over it. Most people think they know only the present; what they know

is the past, which they have already experienced, or read about. The

difference with me is that I can see what's on both sides of the

knife-edge."

Weill put another cigarette in his mouth and bent his head to the

flame of his lighter. For a moment, he sat motionless, his thin face

rigid.

"What do you want me to do?" he asked. "I'm a lawyer, not a

psychiatrist."

"I want a lawyer. This is a legal matter. Whitburn's talking about

voiding my tenure contract. You helped draw it; I have a right to

expect you to help defend it."

"Ed, have you been talking about this to anybody else?" Weill asked.

"You're the first person I've mentioned it to. It's not the sort of

thing you'd bring up casually, in a conversation."

"Then how'd Whitburn get hold of it?"

"He didn't, not the way I've given it to you. But I made a couple of

slips, now and then. I made a bad one yesterday morning."

He told Weill about it, and about his session with the president of

the college that morning. The lawyer nodded.

"That was a bad one, but you handled Whitburn the right way," Weill

said. "What he's most afraid of is publicity, getting the college

mixed up in anything controversial, and above all, the reactions of

the trustees and people like that. If Dacre or anybody else makes any

trouble, he'll do his best to cover for you. Not willingly, of course,

but because he'll know that that's the only way he can cover for

himself. I don't think you'll have any more trouble with him. If you

can keep your own nose clean, that is. Can you do that?"

"I believe so. Yesterday I got careless. I'll not do that again."

"You'd better not." Weill hesitated for a moment. "I said I was a

lawyer, not a psychiatrist. I'm going to give you some psychiatrist's

advice, though. Forget this whole thing. You say you can bring these

impressions into your conscious mind by concentrating?" He waited

briefly; Chalmers nodded, and he continued: "Well, stop it. Stop

trying to harbor this stuff. It's dangerous, Ed. Stop playing around

with it."

"You think I'm crazy, too?"

Weill shook his head impatiently. "I didn't say that. But I'll say,

now, that you're losing your grip on reality. You are constructing a

system of fantasies, and the first thing you know, they will become

your reality, and the world around you will be unreal and illusory.

And that's a state of mental incompetence that I can recognize, as a

lawyer."

"How about the _Kilroy_?"

Weill looked at him intently. "Ed, are you sure you did have that

experience?" he asked. "I'm not trying to imply that you're

consciously lying to me about that. I am suggesting that you

manufactured a memory of that incident in your subconscious mind, and

are deluding yourself into thinking that you knew about it in advance.

False memory is a fairly common thing, in cases like this. Even the

little psychology I know, I've heard about that. There's been talk

about rockets to the Moon for years. You included something about that

in your future-history fantasy, and then, after the event, you

convinced yourself that you'd known all about it, including the

impromptu christening of the rocket, all along."

A hot retort rose to his lips; he swallowed it hastily. Instead, he

nodded amicably.

"That's a point worth thinking of. But right now, what I want to know

is, will you represent me in case Whitburn does take this to court and

does try to void my contract?"

"Oh, yes; as you said, I have an obligation to defend the contracts I

draw up. But you'll have to avoid giving him any further reason for

trying to void it. Don't make any more of these slips. Watch what you

say, in class or out of it. And above all, don't talk about this to

anybody. Don't tell anybody that you can foresee the future, or even

talk about future probabilities. Your business is with the past;

stick to it."

* * * * *

The afternoon passed quietly enough. Word of his defiance of Whitburn

had gotten around among the faculty--Whitburn might have his secretary

scared witless in his office, but not gossipless outside it--though it

hadn't seemed to have leaked down to the students yet. Handley, the

Latin professor, managed to waylay him in a hallway, a hallway Handley

didn't normally use.

"The tenure-contract system under which we hold our positions here is

one of our most valuable safeguards," he said, after exchanging

greetings. "It was only won after a struggle, in a time of public

animosity toward all intellectuals, and even now, our professional

position would be most insecure without it."

"Yes. I found that out today, if I hadn't known it when I took part in

the struggle you speak of."

"It should not be jeopardized," Handley declared.

"You think I'm jeopardizing it?"

Handley frowned. He didn't like being pushed out of the safety of

generalization into specific cases.

"Well, now that you make that point, yes. I do. If Doctor Whitburn

tries to make an issue of ... of what happened yesterday ... and if

the court decides against you, you can see the position all of us will

be in."

"What do you think I should have done? Given him my resignation when

he demanded it? We have our tenure-contracts, and the system was

instituted to prevent just the sort of arbitrary action Whitburn tried

to take with me today. If he wants to go to court, he'll find that

out."

"And if he wins, he'll establish a precedent that will threaten the

security of every college and university faculty member in the state.

In any state where there's a tenure law."

Leonard Fitch, the psychologist, took an opposite attitude. As

Chalmers was leaving the college at the end of the afternoon, Fitch

cut across the campus to intercept him.

"I heard about the way you stood up to Whitburn this morning, Ed," he

said. "Glad you did it. I only wish I'd done something like that three

years ago.... Think he's going to give you any real trouble?"

"I doubt it."

"Well, I'm on your side if he does. I won't be the only one, either."

"Well, thank you, Leonard. It always helps to know that. I don't think

there'll be any more trouble, though."

* * * * *

He dined alone at his apartment, and sat over his coffee, outlining

his work for the next day. When both were finished, he dallied

indecisively, Weill's words echoing through his mind and raising

doubts. It was possible that he had been manufacturing the whole thing

in his subconscious mind. That was, at least, a more plausible theory

than any he had constructed to explain an ability to produce real

knowledge of the future. Of course, there was that business about the

_Kilroy_. That had been too close on too many points to be dismissed

as coincidence. Then, again, Weill's words came back to disquiet him.

Had he really gotten that before the event, as he believed, or had he

only imagined, later, that he had?

There was one way to settle that. He rose quickly and went to the

filing-cabinet where he kept his future-history notes and began

pulling out envelopes. There was nothing about the _Kilroy_ in the

Twentieth Century file, where it should be, although he examined each

sheet of notes carefully. The possibility that his notes on that might

have been filed out of place by mistake occurred to him; he looked in

every other envelope. The notes, as far as they went, were all filed

in order, and each one bore, beside the future date of occurrence, the

date on which the knowledge--or must he call it delusion?--had come to

him. But there was no note on the landing of the first unmanned rocket

on Luna.

He put the notes away and went back to his desk, rummaging through the

drawers, and finding nothing. He searched everywhere in the apartment

where a sheet of paper could have been mislaid, taking all his

books, one by one, from the shelves and leafing through them, even

books he knew he had not touched for more than three years. In the

end, he sat down again at his desk, defeated. The note on the _Kilroy_

simply did not exist.

Of course, that didn't settle it, as finding the note would have. He

remembered--or believed he remembered--having gotten that item of

knowledge--or delusion--in 1970, shortly before the end of the school

term. It hadn't been until after the fall opening of school that he

had begun making notes. He could have had the knowledge of the robot

rocket in his mind then, and neglected putting it on paper.

He undressed, put on his pajamas, poured himself a drink, and went to

bed. Three hours later, still awake, he got up, and poured himself

another, bigger, drink. Somehow, eventually, he fell asleep.

* * * * *

The next morning, he searched his desk and book-case in the office at

school. He had never kept a diary; now he was wishing that he had.

That might have contained something that would be evidence, one way or

the other. All day, he vacillated between conviction of the reality of

his future knowledge and resolution to have no more to do with it.

Once he decided to destroy all the notes he had made, and thought of

making a special study of some facet of history, and writing another

book, to occupy his mind.

After lunch, he found that more data on the period immediately before

the Thirty Days' War was coming into his consciousness. He resolutely

suppressed it, knowing as he did that it might never come to him

again. That evening, too, he cooked dinner for himself at his

apartment, and laid out his class-work for the next day. He'd better

not stay in, that evening; too much temptation to settle himself by

the living-room fire with his pipe and his notepad and indulge in the

vice he had determined to renounce. After a little debate, he decided

upon a movie; he put on again the suit he had taken off on coming

home, and went out.

* * * * *

The picture, a random choice among the three shows in the

neighborhood, was about Seventeenth Century buccaneers; exciting

action and a sound-track loud with shots and cutlass-clashing. He let

himself be drawn into it completely, and, until it was finished, he

was able to forget both the college and the history of the future.

But, as he walked home, he was struck by the parallel between the

buccaneers of the West Indies and the space-pirates in the days of the

dissolution of the First Galactic Empire, in the Tenth Century of the

Interstellar Era. He hadn't been too clear on that period, and he

found new data rising in his mind; he hurried his steps, almost

running upstairs to his room. It was long after midnight before he had

finished the notes he had begun on his return home.

Well, that had been a mistake, but he wouldn't make it again. He

determined again to destroy his notes, and began casting about for a

subject which would occupy his mind to the exclusion of the future.

Not the Spanish Conquistadores; that was too much like the early

period of interstellar expansion. He thought for a time of the Sepoy

Mutiny, and then rejected it--he could "remember" something much like

that on one of the planets of the Beta Hydrae system, in the Fourth

Century of the Atomic Era. There were so few things, in the history of

the past, which did not have their counter-parts in the future. That

evening, too, he stayed at home, preparing for his various classes for

the rest of the week and making copious notes on what he would talk

about to each. He needed more whiskey to get to sleep that night.

Whitburn gave him no more trouble, and if any of the trustees or

influential alumni made any protest about what had happened in Modern

History IV, he heard nothing about it. He managed to conduct his

classes without further incidents, and spent his evenings trying, not

always successfully, to avoid drifting into "memories" of the

future....

* * * * *

He came into his office that morning tired and unrefreshed by the few

hours' sleep he had gotten the night before, edgy from the strain, of

trying to adjust his mind to the world of Blanley College in mid-April

of 1973. Pottgeiter hadn't arrived yet, but Marjorie Fenner was

waiting for him; a newspaper in her hand, almost bursting with

excitement.

"Here; have you seen it, Doctor Chalmers?" she asked as he entered.

He shook his head. He ought to read the papers more, to keep track of

the advancing knife-edge that divided what he might talk about from

what he wasn't supposed to know, but each morning he seemed to have

less and less time to get ready for work.

"Well, look! Look at that!"

She thrust the paper into his hands, still folded, the big, black

headline where he could see it.

KHALID IB'N HUSSEIN ASSASSINATED

He glanced over the leading paragraphs. Leader of Islamic Caliphate

shot to death in Basra ... leaving Parliament Building for his palace

outside the city ... fanatic, identified as an Egyptian named Mohammed

Noureed ... old American submachine-gun ... two guards killed and a

third seriously wounded ... seized by infuriated mob and stoned to

death on the spot....

For a moment, he felt guilt, until he realized that nothing he could

have done could have altered the event. The death of Khalid ib'n

Hussein, and all the millions of other deaths that would follow it,

were fixed in the matrix of the space-time continuum. Including,

maybe, the death of an obscure professor of Modern History named

Edward Chalmers.

"At least, this'll be the end of that silly flap about what happened a

month ago in Modern Four. This is modern history, now; I can talk

about it without a lot of fools yelling their heads off."

She was staring at him wide-eyed. No doubt horrified at his

cold-blooded attitude toward what was really a shocking and senseless

crime.

"Yes, of course; the man's dead. So's Julius Caesar, but we've gotten

over being shocked at his murder."

He would have to talk about it in Modern History IV, he supposed;

explain why Khalid's death was necessary to the policies of the

Eastern Axis, and what the consequences would be. How it would hasten

the complete dissolution of the old U. N., already weakened by the

crisis over the Eastern demands for the demilitarization and

internationalization of the United States Lunar Base, and necessitate

the formation of the Terran Federation, and how it would lead,

eventually, to the Thirty Days' War. No, he couldn't talk about that;

that was on the wrong side of the knife-edge. Have to be careful about

the knife-edge; too easy to cut himself on it.

* * * * *

Nobody in Modern History IV was seated when he entered the room; they

were all crowded between the door and his desk. He stood blinking,

wondering why they were giving him an ovation, and why Kendrick and

Dacre were so abjectly apologetic. Great heavens, did it take the

murder of the greatest Moslem since Saladin to convince people that he

wasn't crazy?

Before the period was over, Whitburn's secretary entered with a note

in the college president's hand and over his signature; requesting

Chalmers to come to his office immediately and without delay. Just

like that; expected him to walk right out of his class. He was

protesting as he entered the president's office. Whitburn cut him off

short.

"Doctor Chalmers,"--Whitburn had risen behind his desk as the door

opened--"I certainly hope that you can realize that there was nothing

but the most purely coincidental connection between the event featured

in this morning's newspapers and your performance, a month ago, in

Modern History Four," he began.

"I realize nothing of the sort. The death of Khalid ib'n Hussein is a

fact of history, unalterably set in its proper place in time-sequence.

It was a fact of history a month ago no less than today."

"So that's going to be your attitude; that your wild utterances of a

month ago have now been vindicated as fulfilled prophesies? And I

suppose you intend to exploit this--this coincidence--to the utmost.

The involvement of Blanley College in a mess of sensational publicity

means nothing to you, I presume."

"I haven't any idea what you're talking about."

"You mean to tell me that you didn't give this story to the local

newspaper, the _Valley Times_?" Whitburn demanded.

"I did not. I haven't mentioned the subject to anybody connected with

the _Times_, or anybody else, for that matter. Except my attorney, a

month ago, when you were threatening to repudiate the contract you

signed with me."

"I suppose I'm expected to take your word for that?"

"Yes, you are. Unless you care to call me a liar in so many words." He

moved a step closer. Lloyd Whitburn outweighed him by fifty pounds,

but most of the difference was fat. Whitburn must have realized that,

too.

"No, no; if you say you haven't talked about it to the _Valley Times_,

that's enough," he said hastily. "But somebody did. A reporter was

here not twenty minutes ago; he refused to say who had given him the

story, but he wanted to question me about it."

"What did you tell him?"

"I refused to make any statement whatever. I also called Colonel

Tighlman, the owner of the paper, and asked him, very reasonably, to

suppress the story. I thought that my own position and the importance

of Blanley College to this town entitled me to that much

consideration." Whitburn's face became almost purple. "He ... he

laughed at me!"

"Newspaper people don't like to be told to kill stories. Not even by

college presidents. That's only made things worse. Personally, I don't

relish the prospect of having this publicized, any more than you do. I

can assure you that I shall be most guarded if any of the _Times_

reporters talk to me about it, and if I have time to get back to my

class before the end of the period, I shall ask them, as a personal

favor, not to discuss the matter outside."

Whitburn didn't take the hint. Instead, he paced back and forth,

storming about the reporter, the newspaper owner, whoever had given

the story to the paper, and finally Chalmers himself. He was livid

with rage.

"You certainly can't imagine that when you made those remarks in class

you actually possessed any knowledge of a thing that was still a month

in the future," he spluttered. "Why, it's ridiculous! Utterly

preposterous!"

"Unusual, I'll admit. But the fact remains that I did. I should, of

course, have been more careful, and not confused future with past

events. The students didn't understand...."

Whitburn half-turned, stopping short.

"My God, man! You _are_ crazy!" he cried, horrified.

The period-bell was ringing as he left Whitburn's office; that meant

that the twenty-three students were scattering over the campus,

talking like mad. He shrugged. Keeping them quiet about a thing like

this wouldn't have been possible in any case. When he entered his

office, Stanly Weill was waiting for him. The lawyer drew him out into

the hallway quickly.

"For God's sake, have you been talking to the papers?" he demanded.

"After what I told you...."

"No, but somebody has." He told about the call to Whitburn's office,

and the latter's behavior. Weill cursed the college president

bitterly.

"Any time you want to get a story in the _Valley Times_, just order

Frank Tighlman not to print it. Well, if you haven't talked, don't."

"Suppose somebody asks me?"

"A reporter, no comment. Anybody else, none of his damn business. And

above all, don't let anybody finagle you into making any claims about

knowing the future. I thought we had this under control; now that

it's out in the open, what that fool Whitburn'll do is anybody's

guess."

Leonard Fitch met him as he entered the Faculty Club, sizzling with

excitement.

"Ed, this has done it!" he began, jubilantly. "This is one nobody can

laugh off. It's direct proof of precognition, and because of the

prominence of the event, everybody will hear about it. And it simply

can't be dismissed as coincidence...."

"Whitburn's trying to do that."

"Whitburn's a fool if he is," another man said calmly. Turning, he saw

that the speaker was Tom Smith, one of the math professors. "I figured

the odds against that being chance. There are a lot of variables that

might affect it one way or another, but ten to the fifteenth power is

what I get for a sort of median figure."

"Did you give that story to the _Valley Times?_" he asked Fitch,

suspicion rising and dragging anger up after it.

"Of course, I did," Fitch said. "I'll admit, I had to go behind your

back and have some of my postgrads get statements from the boys in

your history class, but you wouldn't talk about it yourself...."

Tom Smith was standing beside him. He was twenty years younger than

Chalmers, he was an amateur boxer, and he had good reflexes. He caught

Chalmers' arm as it was traveling back for an uppercut, and held it.

"Take it easy, Ed; you don't want to start a slugfest in here. This is

the Faculty Club; remember?"

"I won't, Tom; it wouldn't prove anything if I did." He turned to

Fitch. "I won't talk about sending your students to pump mine, but at

least you could have told me before you gave that story out."

"I don't know what you're sore about," Fitch defended himself. "I

believed in you when everybody else thought you were crazy, and if I

hadn't collected signed and dated statements from your boys, there'd

have been no substantiation. It happens that extrasensory perception

means as much to me as history does to you. I've believed in it ever

since I read about Rhine's work, when I was a kid. I worked in ESP for

a long time. Then I had a chance to get a full professorship by coming

here, and after I did, I found that I couldn't go on with it, because

Whitburn's president here, and he's a stupid old bigot with an

air-locked mind...."

"Yes." His anger died down as Fitch spoke. "I'm glad Tom stopped me

from making an ass of myself. I can see your side of it." Maybe that

was the curse of the professional intellectual, an ability to see

everybody's side of everything. He thought for a moment. "What else

did you do, beside hand this story to the _Valley Times?_ I'd better

hear all about it."

"I phoned the secretary of the American Institute of Psionics and

Parapsychology, as soon as I saw this morning's paper. With the

time-difference to the East Coast, I got him just as he reached his

office. He advised me to give the thing the widest possible publicity;

he thought that would advance the recognition and study of

parapsychology. A case like this can't be ignored; it will demand

serious study...."

"Well, you got your publicity, all right. I'm up to my neck in it."

There was an uproar outside. The doorman was saying, firmly:

"This is the Faculty Club, gentlemen; it's for members only. I don't

care if you gentlemen are the press, you simply cannot come in here."

"We're all up to our necks in it," Smith said. "Leonard, I don't care

what your motives were, you ought to have considered the effect on the

rest of us first."

"This place will be a madhouse," Handley complained. "How we're going

to get any of these students to keep their minds on their work...."

"I tell you, I don't know a confounded thing about it," Max

Pottgeiter's voice rose petulantly at the door. "Are you trying to

tell me that Professor Chalmers murdered some Arab? Ridiculous!"

* * * * *

He ate hastily and without enjoyment, and slipped through the kitchen

and out the back door, cutting between two frat-houses and circling

back to Prescott Hall. On the way, he paused momentarily and chuckled.

The reporters, unable to storm the Faculty Club, had gone off in chase

of other game and had cornered Lloyd Whitburn in front of

Administration Center. They had a jeep with a sound-camera mounted on

it, and were trying to get something for telecast. After gesticulating

angrily, Whitburn broke away from them and dashed up the steps and

into the building. A campus policeman stopped those who tried to

follow.

His only afternoon class was American History III. He got through it

somehow, though the class wasn't able to concentrate on the

Reconstruction and the first election of Grover Cleveland. The halls

were free of reporters, at least, and when it was over he hurried to

the Library, going to the faculty reading-room in the rear, where he

could smoke. There was nobody there but old Max Pottgeiter, smoking a

cigar, his head bent over a book. The Medieval History professor

looked up.

"Oh, hello, Chalmers. What the deuce is going on around here? Has

everybody gone suddenly crazy?" he asked.

"Well, they seem to think I have," he said bitterly.

"They do? Stupid of them. What's all this about some Arab being shot?

I didn't know there were any Arabs around here."

"Not here. At Basra." He told Pottgeiter what had happened.

"Well! I'm sorry to hear about that," the old man said. "I have a

friend at Southern California, Bellingham, who knew Khalid very well.

Was in the Middle East doing some research on the Byzantine Empire;

Khalid was most helpful. Bellingham was quite impressed by him; said

he was a wonderful man, and a fine scholar. Why would anybody want to

kill a man like that?"

He explained in general terms. Pottgeiter nodded understandingly:

assassination was a familiar feature of the medieval political

landscape, too. Chalmers went on to elaborate. It was a relief to talk

to somebody like Pottgeiter, who wasn't bothered by the present

moment, but simply boycotted it. Eventually, the period-bell rang.

Pottgeiter looked at his watch, as from conditioned reflex, and then

rose, saying that he had a class and excusing himself. He would have

carried his cigar with him if Chalmers hadn't taken it away from him.

After Pottgeiter had gone Chalmers opened a book--he didn't notice

what it was--and sat staring unseeing at the pages. So the moving

knife-edge had come down on the end of Khalid ib'n Hussein's life;

what were the events in the next segment of time, and the segments to

follow? There would be bloody fighting all over the Middle East--with

consternation, he remembered that he had been talking about that to

Pottgeiter. The Turkish army would move in and try to restore order.

There would be more trouble in northern Iran, the Indian Communists

would invade Eastern Pakistan, and then the general war, so long

dreaded, would come. How far in the future that was he could not

"remember," nor how the nuclear-weapons stalemate that had so far

prevented it would be broken. He knew that today, and for years

before, nobody had dared start an all-out atomic war. Wars, now, were

marginal skirmishes, like the one in Indonesia, or the steady

underground conflict of subversion and sabotage that had come to be

called the Subwar. And with the United States already in possession of

a powerful Lunar base.... He wished he could "remember" how events

between the murder of Khalid and the Thirty Day's War had been spaced

chronologically. Something of that had come to him, after the incident

in Modern History IV, and he had driven it from his consciousness.

* * * * *

He didn't dare go home where the reporters would be sure to find him.

He simply left the college, at the end of the school-day, and walked

without conscious direction until darkness gathered. This morning,

when he had seen the paper, he had said, and had actually believed,

that the news of the murder in Basra would put an end to the trouble

that had started a month ago in the Modern History class. It hadn't:

the trouble, it seemed, was only beginning. And with the newspapers,

and Whitburn, and Fitch, it could go on forever....

It was fully dark, now; his shadow fell ahead of him on the sidewalk,

lengthening as he passed under and beyond a street-light, vanishing as

he entered the stronger light of the one ahead. The windows of a cheap

cafe reminded him that he was hungry, and he entered, going to a table

and ordering something absently. There was a television screen over

the combination bar and lunch-counter. Some kind of a comedy

programme, at which an invisible studio-audience was laughing

immoderately and without apparent cause. The roughly dressed customers

along the counter didn't seem to see any more humor in it than he did.

Then his food arrived on the table and he began to eat without really

tasting it.

After a while, an alteration in the noises from the television

penetrated his consciousness; a news-program had come on, and he

raised his head. The screen showed a square in an Eastern city; the

voice was saying:
