The disappearance of John Henderson was most spectacular. It occurred

while he was at the blackboard working an example in multiple

integration for his ten o'clock class. The incompleted problem remained

on the board for three days while the police worked on the case. It, a

wrist watch and a sterling silver monogrammed belt buckle, lying on the

floor near where he had stood, were all the physical evidence they had

to go on.

There was plenty of eye-witness evidence. The class consisted of

forty-three pupils. They all had their eyes on him in varying degrees of

attention when it happened. Their accounts of what happened all agreed

in important details. Even as to what he had been saying.

In the reports that went into the police files he was quoted with a high

degree of certainty as having said, "Integration always brings into the

picture a constant which was not present. This constant of integration

is, in a sense, a variable. But a different type of variable than the

mathematical unknown. It might be said to be a logical variable--"

The students were in unanimous agreement and, at this point, Dr.

Henderson came to an abrupt stop in his lecture. Suddenly, an expression

of surprise appeared on his face. It was succeeded by an exclamation of

triumph. And he simply vanished from the spot.

He didn't fade away, rise, drop into the floor, or take any time

vanishing. He simply stopped being there.

[Illustration: _He just wasn't there any more._]

The police searched his room in the nearby Vanderbilt Arms Hotel. They

turned a portrait of the missing math professor to the newspapers to

publish. Arbright University offered a reward of one hundred dollars to

anyone who had seen him.

The police also found a savings pass book in his room. It had a balance

of three thousand eight hundred and forty dollars, which had been built

up to that figure by steady monthly deposits over a period of years. It

also had a withdrawal of three hundred and twenty dollars two days

before the disappearance. They were sure they were on the path to a

motive. This avenue of exploration came to an abrupt end with the

discovery that he had traded in his last year's car on a new one, and

that sum had been necessary to complete the deal.

After the third day the blackboard had been erased and the classroom

released for its regular classes. Police enthusiasm dropped to the norm

of what they called legwork. Finding out who the missing man's

acquaintances and friends were, calling on them and talking to them in

the hopes of picking up something they could go on.

They passed Martin Grant by because they had heard from him in their

initial work. In fact, he had been a little too present for their

tastes.

After ten days they dropped the case from the active blotter. The

University, seeing that there was little likelihood of having to shell

out the reward money, increased it to five hundred dollars.

But Martin Grant continued to ponder over a conversation he himself had

had with John Henderson during a dinner six weeks to the day before his

old friend had vanished. He remembered his own words...

* * * * *

"... and so you see, John, by following this trail, I've arrived at a

theory that has to do with the basic nature of the universe--of all

reality. Yet things don't behave as they would if my theory were

operating."

John Henderson frowned into space, disturbed. Visibly disturbed. Martin

watched him with a twinkle in his eyes.

"You must have gone off the track on it somewhere, Martin," John said

suddenly, as though trying more to convince himself than his listener.

Martin shook his head with slow positiveness. "You followed every step.

We spent four hours on it." He took pity on his friend. "Don't let it

bother you. I regard it as just an intellectual curiosity. I've included

it in my next book on that basis."

A new voice broke in. "What is it, Dad? One of your ten-thousand-word

shaggy dog jokes?" This from Fred Grant, 16, student in the senior grade

at the Hortense Bartholemew High School, and an only child of Martin

Grant.

"A little more respect toward your father," Martin said with much

sternness.

"Yes, Father."

"It was my _theory_."

John Henderson said, "But, Martin, I don't know what to think now. Of

course there must be some fallacy that I've missed. The way things stand

though, I--" He chuckled uncomfortably. "I begin to doubt myself. I

can't quite classify it as an intellectual curiosity."

"What else can you do with it?" Martin said. "I know your trouble. It's

a common one. You have a tendency to believe things or disbelieve them.

Now you've been presented with something your intellect demands that you

believe, while your experience shouts, 'lie'."

"Is Fred able to understand it?" John asked, smiling at the youngster

with fond and unconscious condescension.

"Not yet," Fred smiled. "I'm still in high school."

"And if you don't want to flunk out you'd better be off to bed at once,"

Martin told him.

"Yes, Father. Good night, Dr. Henderson."

Fred's departure left a vacuum in the conversation that took a minute to

fill. John Henderson frowned himself back to where he had been before

the boy had arrived. When he got there he frowned even more, because it

was a state of mental confusion that seemed to have no way of being

resolved.

"Maybe we can get at it this way," he said. "Let's postulate that your

theory is the only logical basis on which reality can rest. B, quite

obviously reality does not rest on this basis. We could make C,

therefore, that reality doesn't rest on a logical basis. But that

doesn't seem to satisfy me. Maybe C could be--no--" He glanced at his

watch, lifted his eyebrows and stood up. "I really didn't know it was so

late. I'll have to be going, Martin. An eight o'clock lecture in the

morning."

Martin made a wry face. "You've awakened my own conscience. I have an

hour or two of work yet before bedtime."

The two men went to the front door. John said, "Thank your wife again

for me. Wonderful dinner. You're lucky, Martin, to have such a good

cook."

* * * * *

That had been six weeks before John Henderson vanished. Martin Grant

mentioned this visit to Horace Smith, one of the teachers in his

department, and got himself and his wife invited for dinner on the

following Friday. Dinner over, the two professors retired to the

library.

Two and a half hours later Horace had assimilated and grasped every

detail of the theory. He then leaned back in his chair and closed his

eyes, fingertips to temples, trying to find some flaw. Finally he shook

his head. "It's no use," he said. "Your theory is logically inescapable.

But--" He frowned. "Where does that place us? Probably where some

schools of thought have always suspected we would wind up eventually.

With the realization that the basic laws of the universe can't be

reached by logic or even by experiment based upon logic."

"I wouldn't say that," Martin objected. "My theory is an intellectual

curiosity, that's all. That's the way I present it in my latest book. By

the way, it's coming out soon. Signed the contract a month ago." He

pulled his thoughts back to the conversation. "After all, one must hold

onto the pragmatic approach to reality. Here is a theory that logic says

must be the only possible way a universe can be constructed and

operate. It's beautiful and logically complete, but not applicable. No

pragmatic value."

"Congratulations on the book. But, damn it," Horace said, "it attacks my

most basic faith. Logic. Reason."

"Faith?" Martin echoed, amused. "Yes, perhaps you're right. That's a

word that's foreign to my thinking. Belief is so unnecessary."

"You don't mean that."

"But I do."

Horace pondered. "I can prove otherwise. You believe--as an

example--that your wife is faithful to you." It was a statement rather

than a question.

"As a matter of fact--I don't. I act upon the greater probability that

she is. I don't hire detectives to follow her. Nor do I throw her into

situations to test her faithfulness. I admit the possibility that she's

unfaithful to me. If evidence came that she was, I might confront her

with the evidence. Where does belief become necessary?"

"Do you believe your son will become a success in life?" Horace asked.

"No. I've done everything I could think of to increase the probability

that he will. One of the things I've done is to instill in him the

realization that belief is unnecessary in thinking. Surely, as a

scientist, you realize that nothing we use in science finds its value or

validity from human belief. If, tomorrow, evidence were brought forth

that trigonometry is based on fallacy I'm sure that mathematicians would

use that evidence to revise their entire field."

"But belief is instinctive; as instinctive as thought itself."

"I admit it's a natural way of thinking. It has to be weeded out."

"So you're sure you don't believe in anything," Horace said slyly.

"Such statements are verbal traps," Martin said. "They mean nothing. You

want me to imply that I believe I believe nothing, and therefore I have

at least one belief. But as a matter of fact I've built up a sort of

mental mechanism for discovering beliefs in my thinking and dispelling

them by going to the roots and showing myself why I believed. Belief

springs up in the mind like weeds in a garden. Constant weeding is the

only solution." He glanced at his watch and frowned uneasily. "Eleven

o'clock. We'd better break this up and join the women. We'll have to get

together again soon. By the way, do you and your wife play Canasta? My

wife loves it."

They had been moving toward the door. Now they entered the living room,

to find the two women playing the game.

"Time we were going, dear," Martin said. "And sometime soon make plans

to have Horace and Ethel over for an evening of four-handed Canasta."

At the front door vows of an early reunion were repeated. But they were

never to be fulfilled. On the following Tuesday Horace vanished.

* * * * *

This time there were no actual eye witnesses. The time was somewhere

between seven and seven-ten Tuesday morning; the place; Horace Smith's

bathroom.

Ethel Smith was in the kitchen preparing breakfast. Horace was in the

bathroom. He called out, "Ethel! I've got it!"

"What have you got?"

But even as Ethel called out, she heard the sound of the electric razor

falling to the tile floor, and there was no answer from the bathroom.

Nothing but silence and, as she described it later, a feeling that she

was alone in the house.

At the time, however, she wasn't alarmed. She half expected some

muttered profanity over the dropping of the razor. She didn't wait for

it exactly. Instead, she picked up the spatula and expertly scooped the

eggs onto their two plates and carried them to the breakfast nook. Next

she poured the coffee. Then, placing some bread in the toaster, she

started back to the stove, calling, "Come and get it, Horace!"

At the stove she started to pick up the aluminum dish containing the

bacon. She paused and repeated her call. "Horace!"

It wasn't until then that it occurred to her the falling of the razor

might have been an ominous sound. Her mind filled with worried images,

she rushed out of the kitchen into the hall leading to the bathroom.

The door was locked.

"Horace!" she called. "Are you all right?" When there was no answer she

pounded on the door. "Horace! Speak to me!"

After that she ran outside and around to the bathroom window. It was

shut and locked, as she already knew. Not only that, it had been stuck

for years.

With an urgency born of a realization that every second might mean the

difference between life and death, she ran back into the house and

called the fire department. Also the family doctor.

By nine-thirty the police had been called in. By eleven o'clock they had

seen the parallel between this disappearance and that of John Henderson.

Martin Grant's first reaction was concern for Ethel. His second reaction

was that, twice, he had presented his theory to someone and that person

had vanished. His third was accompanied by a twinge of fear. He had just

finished presenting his theory to the senior physics class!

This was followed by an amazing realization. He was conceding that there

might be a connection between his theory and the disappearances. He

laughed it off, but it returned. It disturbed him.

It continued to bother him on Wednesday, so he began to search his mind

for reasons. Eventually he found them. There was a distinct analogy

between a theory that didn't agree with observable reality, and a pair

of disappearances which violated known methods of disappearing.

The analogy was so clear that he began to feel there might be a

functional relation between the two. Of course, he concluded, it would

be reasonably certain if a large number of the students in the senior

group were to vanish also.

This intellectual conclusion became an anxiety neurosis.

So, on Wednesday--after he had scanned the room anxiously to see how

many students were absent and discovered to his intense relief that they

were all there--he spent the full hour lecturing on the necessity--the

_vital_ necessity--of unbelief in all things, especially scientific

theories.

But would it work? He vaguely remembered giving Horace a similar

lecture.

Wednesday night just before retiring he had another disturbing thought.

He had explained the theory to his son. But that had been weeks before,

and Fred was steeped in the mechanism of unbelief. Good thing, or he

might have been the first to disappear.

"What's the matter with you, Martin? Can't you even answer when--" The

rest of what his wife was saying faded in the startled realization that

he was eating dinner.

"Sorry, dear," he murmured. "I was thinking." He was trying to recall

something that might tell him what day it was. It was obviously evening

or they wouldn't be eating dinner. "Uh," he said casually, "what day is

today?"

"Saturday," Fred said.

"Now Fred, don't tease your father about his absent-mindedness. This is

Thursday."

Thursday! That was right. He had given the lecture on the necessity of

unbelief today. There was tomorrow, when he could see if any of the

class had disappeared yet. He couldn't be certain, of course. Just

because a student didn't show up didn't mean he or she had vanished.

He fixed his eyes on Fred, across the table, and smiled. Fred, at least,

was a source of comfort. He knew the theory and hadn't vanished.

"Dad," Fred said. "I've been wondering if you saw a point of similarity

in the two disappearances?"

Martin thought, good heavens, does he have any inkling of what I've been

thinking? Of course not! He's just fumbling. Better to discourage him.

"Sorry, son. There aren't any similarities except accidental ones. I've

had the confidence of the police on this. The cases are quite

unrelated."

Fred refused to be sidetracked. "Dr. Henderson's face lit up as though a

sudden idea had struck him. I talked with some of his students. That's

what they all thought. And Horace Smith shouted to his wife, 'Ethel!

I've got it!' The next instant in each case they vanished into thin

air."

"But that doesn't mean a thing."

* * * * *

In the privacy of his study Martin Grant allowed himself to become

excited. Fred had unwittingly come upon the vital clue to the two

disappearances.

"Let's be clear about this," he said to himself, drumming on his desk

nervously with his fingers. "Undoubtedly there's a connection between

the vanishing and my theory. Both Horace and John arrived at something

I've missed. And since my theory is exhaustive it can't be there. It

must be--yes--it _must_ be that they went a step farther." He pondered

this a moment and added grudgingly, "A step I have missed." Then even

more grudgingly, "An obvious step."

Automatically he opened a drawer and brought out a sheet of paper and a

pencil. He wrote:

_The theory contains within itself the proof that the universe must, by

logical necessity, be constructed according to said theory. But

observation and experience say this is not true._

He frowned at what he had written. This was the conclusion to which he

had led both men. It was the conclusion upon which he had rested. They,

obviously, had not rested there. They had gone on.

Under what he had written he wrote "_Either_:" on the left hand margin.

Two inches under it he wrote, "_Or_:" Then he frowned at them. Suddenly

he began writing rapidly after the _Either_: "_The universe is not

constructed according to logical necessity._"

He hesitated, studying what he had written. Then, pursing his lips, he

slowly wrote after the _Or_: "_The observable universe is not the

universe._"

He nodded to himself. That hit at the core of the matter. A was X. B was

not X. Therefore B was not A. Even though A and B were both called

universe.

The question was, then--did the universe-of-logical-necessity exist? If

so, what relationship did it have to the observable universe which quite

obviously did exist?

Was that the question, the answer to which, gained in a moment of

insight, had caused two men to utterly vanish?

He sighed with real regret. There was no way of knowing. Possibly a

mechanical brain of the most advanced type could come out with a

comprehensive picture after solving thousands of successive equations.

Knowledge of simple basics was a far cry from a fully expanded system.

He pushed the sheet of paper away with a show of irritation. He was

missing something. He was on the wrong track. Neither John nor Horace

had the mental equipment to make more than a simple step beyond what he

had accomplished. That was certain. It was equally certain that he could

and would make it.

A startled expression appeared on his face. "Oh good lord!" he groaned.

"My book. I must do something about that the first thing tomorrow. I--"

He opened the drawer of his desk and took out an oblong of paper, the

check against advance royalties. "I'll return this and not let them

publish it. First thing in the morning. And from now on I resolve not to

think of my theory or what caused John and Horace to vanish."

Folding the check neatly, he stuck it in his billfold and then started

to read a book that interested him. He became engrossed in it. Half an

hour later he came to enough to realize he was on safe ground, sigh with

relief, and sink back into the trains of thought of the book.

It was a nice feeling to know he was safe.

* * * * *

It was Friday. The sun was shining brightly and the monotony of the blue

sky was relieved here and there by filmy white clouds that gave it a

pleasing three-dimensionalness.

But to Martin Grant there was something unreal about things. He decided

it must be the light. Things stood out with too sharp clarity.

When he reached his office at the university he made arrangements for a

substitute to take his ten o'clock class. Then he called the publishing

company and made an appointment for ten-fifteen.

The hour from nine to ten seemed interminably long. He found it almost

impossible to concentrate on such an unimportant subject as the

application of tensor analysis to electronic circuits.

Ten o'clock came. He hurried to the parking lot and got in his car. It

was real and comforting. But once again everything outside the

windshield seemed too sharply defined.

He timed himself on the way across town to the publishing house. He

would have to allow himself the same time to return for his eleven

o'clock class. It took twelve minutes, plus another two to find a

parking place. Two minutes from the car to the eleventh floor. He was

frowning at his watch as he entered the publisher's office.

"Well, well, Dr. Grant! Glad to see you. I suppose you're anxious to see

your book ready for market. It's coming very well. Just came back from

the typesetters and is going into its first printing right away."

"Huh?" Martin said, completing his mental arithmetic and jerking into an

awareness of his surroundings. "Oh, hello Mr. Browne," he said. "I was

just figuring my time. I have an eleven o'clock class. I can only stay

twenty-seven minutes. That gives me a three minute margin of error for

traffic delays."

"I see," the publisher said, a twinkle in his eye. "As I was just

saying, your book--"

"Oh yes, my book," Martin interrupted. "Just a minute." He took out his

billfold and extracted the check, handing it to Mr. Browne.

"What's this for?" Mr. Browne asked, unfolding it. "Oh, the advance

royalty check. Is something wrong with it?"

"I'm returning it," Martin said. "I can't let you publish my book."

"Can't let me publish it!" Browne exclaimed. "Why not? Don't tell me it

infringes on someone else's copyright!"

"No. Nothing like that. I've merely decided I don't want it published.

I'm returning your check."

"Well now, look!" Browne said. "We're a business establishment. You

signed a contract. We signed one too. It protects both of us against

just this sort of thing, you know." He studied Martin thoughtfully. "Sit

down and relax," he invited. "I'm human. Tell me why you don't want it

published. Maybe I might agree with you. We have over a thousand dollars

tied up already in typesetting, but--"

Martin took the seat and glanced nervously at his watch to make sure the

twenty-seven minutes hadn't elapsed.

"I've just changed my mind," he said curtly. "There are certain

things--I'm the head of a department, you know. I must watch my

reputation. That's it, my reputation. On due reflection I believe the

book might hurt my standing."

"In what way?" Browne asked. "To tell you the truth, your other book

did so well I didn't bother reading this one."

"There's a--" Martin brought himself up short. So Browne hadn't read it.

So much the better. At least he wouldn't vanish. "I'm afraid," he added

with a self-conscious chuckle that he hoped was genuine enough to pass,

"the subject matter is a little too crackpottish in spots. That's the

whole thing. It would reflect on my reputation."

"Maybe we could do a little editing on it," Browne said. "Cut out the

parts you think crackpottish and substitute something else in those

pages. I'll get the galleys and we can look at them."

"No!" Martin said. "No, I'm afraid we would have to cut out at least

half of the book. No. The best thing is to forget it, but I'll make good

your typesetting loss. I can pay you two hundred dollars right away and

fifty dollars a month."

Browne lit a cigarette slowly, his eyes on Martin. "You're serious,

aren't you," he said. "I'll tell you what we'll do. We'll let the whole

thing ride for the present. Maybe later--"

"No!" Martin said. "It must never be published! It's very vital that it

never be published."

"Okay," Browne said. "We won't publish it. We have the contract, but--we

won't publish it."

"Thanks, very much," Martin said. "I must hurry back."

The publisher stared thoughtfully at the closed door after Martin had

gone. He glanced down at the check.

* * * * *

Lecture room 304 was very large, capable of holding four hundred

students in its successive tiers of seats, plus the teacher on his

raised platform immediately in front of the large blackboard. In

previous years there had been instances of students slipping out after

roll call. In spite of everything, it had happened.

Therefore a new system had been inaugurated. Before roll call Martin

marched to the back of the room to the only exit and locked it.

Pocketing the key, he returned to his podium. It had been going on this

way for two years, and was now automatic.

The day watchman, making his rounds, approached this door at precisely

two thirty-four. He heard violent pounding. Along with the pounding

there was a loud, hoarse voice, gasping, "Lemme out! Lemme out!"

The watchman consulted his clock--the one he used to make a record of

his rounds--and determined that it was two thirty-four. He knew that it

was Dr. Grant's senior theoretical physics lecture period. He recalled

that a couple of years before Dr. Grant had had trouble with students

slipping out after roll call. But it occurred to him that it was hardly

possible to sneak out, even on Dr. Grant, absent-minded as he was, by

pounding on the door and shouting, "Lemme out!" in a terrified tone of

voice.

He therefore stopped and knocked on the door, calling, "What's going on

in there?"

Whoever was doing the pounding and shouting evidently didn't hear him.

Waiting no longer, the day watchman used his master key on the door.

A smallish young man, later identified as Mark Smythe, attempted to run

past him into the hall. The watchman blocked Mark's escape and looked

toward the podium in an automatic appeal to Dr. Grant.

Dr. Grant was not there. The podium was unoccupied. So were all four

hundred seats. There was, in fact, no one in room 304 except the one

terrified student.

In due course the police arrived, along with the regents. By five

o'clock it had become certain that the greatest mass disappearance of

all times had occurred, with Mark Smythe as the sole witness.

He stuck to his story through repeated detailed questionings, and in the

end the police were stuck with it.

According to Smythe, class had begun as usual. Dr. Grant had waited

until one minute after the bell had sounded, then had marched back and

locked the door, and returned to the front. He had rapidly scanned the

room to see if there were any absences, quickly called half a dozen

names he was uncertain of, and marked the attendance slip. The police

found it still resting on the table where he had placed it.

Then he had begun his lecture by remarking that they were behind

schedule and would have to catch up. He had been speaking less than five

minutes when a student by the name of Marvin Green jumped to his feet in

great excitement, waving his hand and shouting, "Dr. Grant! Dr. Grant!"

Dr. Grant had stopped his lecture and frowned darkly, then said, "If you

will please take your seat--"

"But Dr. Grant!" Marvin Green had interrupted him excitedly. "I've got

it! I've got it!"

What had happened then was impossible for the mind to accept. Marvin

Green had simply ceased to be.

There had been a stunned silence. And in that silence, it went on.

Student after student popping out of existence in what seemed to be a

chain reaction.

He wasn't aware when Dr. Grant vanished. All he knew was that when at

last he was alone he looked toward the podium and the professor was also

gone.

He kept waiting to go himself. When he didn't, he lost the fear that had

rooted him to the spot, and rushed to the exit where he at first tried

to break down the door and make his escape, then subsided into pounding

and shouting for help when he realized his physical strength was

insufficient for the job.

Questioning didn't bring out any additional fact, nor alter any

statement. There had been no sound to the vanishing, no movement of the

person that could be considered significant, no flashes of light, no

strange odors. Nothing.

* * * * *

Fred Grant got the flash on his hot rod radio on the way home from high

school.

At the end of the report Fred wrote down Mark Smythe's address on a

scrap of paper, and drove home to be with his mother. It was three days

before he could get away.

On the morning of the third day, his aunt Emily arrived to take charge

of things, and he was able to slip away. He drove immediately to Mark

Smythe's address. It was one of the better class rooming houses near the

campus. The land-lady wasn't going to let him in nor announce him until

he explained he was the son of the professor who had vanished. She

immediately swung to the other extreme and didn't bother to find out if

Mark wanted to see him.

"My father was your teacher," Fred said.

"Oh? Come on in."

There were tennis rackets. On the bookshelves there were tennis books.

On a table there was a tennis trophy. Otherwise there was just a bed, a

rug, and two or three chairs.

"I don't know what I can tell you more than I've already told the police

and the reporters," Mark said apologetically. "I guess it's tough,

losing your father...."

"Yeah," Fred agreed. "I wanted to ask you something though. Dad gave a

lecture on his new theory a few days ago, didn't he?"

Mark looked at him blankly. Then, "Oh! I guess he did. As a matter of

fact I didn't pay much attention to it." He grinned. Then he remembered

he should be solemn and stopped grinning. "I--I sort of slipped by it.

He made the mistake of telling us ahead of time it was off the course

and no questions on it would be in the finals, so I more or less rested

up during the period for a tennis match afterwards. Why?"

"Didn't you get any of what he said?" Fred persisted.

"Oh, a little," Mark admitted. "It was about some system of arriving at

the basic laws of nature by pure logic, only what you arrived at didn't

agree with facts. Some kind of intellectual curiosity." He thought a

minute. "Oh," he said, "I see what you want. Didn't he leave any notes

on it? It would be too bad if his theory was lost to the world now

that--" He left the rest unsaid.

"Maybe you can remember something," Fred coaxed. "Anything. Did he talk

about his theory again?"

"Next day he gave a lecture on the necessity of unbelief in modern

science. It was pretty good. He overemphasized it, though. Some of the

kids thought he was making a religion of unbelief."

"What did they say about his theory?" Fred asked quickly.

"Oh, they were quite impressed. Two of them live--lived here in the

rooming house. They were up here that evening tossing it back and forth.

I was too tired from the tag match. I let them talk."

"What did they think about it?"

Mark frowned in an effort to recall. "It had to do with this universe

being basically illogical, or at least seeming to be, because it didn't

agree with your father's theory. They started building up fantasies on

it. One I remember was a good one."

"What was that?"

"I think it was Jimmy. He said it would be funny if we were here

because we believed this universe was the only real one. Something about

inherited memory. Our coming from a long line of people who believed

this was the only place, because all our ancestors who didn't believe it

shot off into some other universe and had their children there. Utterly

crazy. You know."

"Yeah, I know," Fred agreed. "You going to be around in case I want to

see you again?"

"God! I hope so!" Mark said. "It makes me nervous."

"You're safe enough," Fred said. "Well--thanks. I'll be seeing you."

* * * * *

He smoothed out the crumpled sheet of paper and glanced at it.

"What do you hope to find, Fred," his mother asked.

"I don't know," he said. "Anything, I--maybe this is something. Look."

Together they read, "Either: the universe is not constructed according

to logical necessity, Or: the observable universe is not the universe."

There were doodlings along the right margin that meant nothing.

"What does it mean?" Mrs. Grant asked.

"Probably just something connected with his classes," Fred shrugged. He

went on searching the waste basket, giving his mother no hint that he

had already found what he was searching for.

From the position of the paper in the waste basket he felt reasonably

sure it had been recently written. It was probably a voicing of thoughts

gained from the disappearance of Horace and John, because up to that

time his father had assumed his theory was just an intellectual

curiosity.

His father couldn't have asked himself if the observable universe might

not be the universe unless something had happened to raise a doubt, or

suggest an alternative as a possibility.

Mrs. Grant's interest lessened. She wandered about the room, perhaps

reliving memories. It gave Fred a chance to put the piece of paper in

his pocket so that when he put everything back in the waste basket his

mother would dismiss the whole search.

There was, of course, the file with the entire theory in it. He knew the

theory by heart, however, and had no need of that file.

"I think I'll go out for a while, Mom," he said.

"All right, Fred," she said disinterestedly.

Outside he climbed behind the wheel of his hot rod and sat there, making

no motion to start the motor. He was thinking.

Mark Smythe had said that he overheard two of his fellow class-men

discussing the theory, one of them remarking that, "It would be funny if

we were here just because we were descended from a long line of people

who believed this was the only place."

Could that be the key?

Take gravitation, for instance. If it were something that some vital

part of you had to believe, and that vital part didn't believe, would

the entire person go flying off into space?

What about inanimate matter? Did it have to believe too? And what about

other forms of life?

Or was everything except human beings just part of the props?

He shook his head. That didn't seem like quite the right track. He took

another.

The human mind builds up a picture of the outside universe through its

senses. Sometimes its ideas are wrong. Right or wrong, inside everyone's

mind is a universe, derived from the outside universe.

What if the outside universe were derived from something? Derived from

what? The real, logically necessary universe? That could be. At least it

seemed to have some value as a starting point.

He tried to reason from that point. Frustration grew in him. He wished

he were older, had his university education behind him. There were so

many things he couldn't begin to deal with.

Maybe he could take the entire problem to some of his father's friends.

He shook his head over this thought. From all that had gone on it was

too likely that the minute one of them discovered something that would

be of help he would disappear before he could tell it!

That raised another point. Why didn't he himself vanish? What was there

different about him?

A lot. His father had instilled in him a lot of the things he himself

could only aspire to. Unbelief was the major thing. Or perhaps it was

the other major thing, remembrance.

His father's voice came into consciousness, saying something he had said

so many times it was grooved deeply in memory, even to the inflections

of voice. "_All psychoses and mental troubles are caused by walled-off

unpleasant memories. The child who trains himself to recall all

unpleasant things and deliberately associate them with the feeling that

they are valuable lessons, but harmless, will grow up in perfect

balance._"

He smiled. He could let flow through consciousness, dozens of incidents

he had taken up with his father.

He was definitely different than others around him. So different

he had systematically disguised it by a front of accepted

behavior--systematically and consciously, under his father's guidance.

There was a chance those differences made him safe. There was a chance

those differences would make it possible for him to find out what caused

the others to vanish, without he himself vanishing.

The other train of thought inserted itself into consciousness again. Was

belief the key to the disappearances?

* * * * *

Mark Smythe hadn't paid attention when the theory was being explained.

The others had undoubtedly lapped it up. The peculiar thing about the

theory was that it was so logical and so inevitable that the mind tended

to accept it, believe it to be true in spite of the evidence of the

senses.

Let us suppose, Fred mused, that deep within the mind there is some

matrix of thought that ties the human to this universe. A matrix that

could conceivably be altered, and when altered would automatically shift

the person to another universe that the altered matrix fitted.

The subconscious usually took time to absorb and react. That was another

thing his father had taught him to observe. Learn something, and it

takes from days to months for it to become lodged in the subconscious

and to rise into operation naturally from there.

John Henderson had taken six weeks to vanish after having learned the

theory. It had taken Horace Smith three and a half days, but he had had

the added factor of Dr. Henderson's disappearance to trigger reactions.

The theoretical physics class had taken three days exactly, and its

vanishing had been a sort of group action or chain reaction, with

intensely emotional reaction after the first student had vanished before

the eyes of the others.

His own father, originator of the theory, had probably fallen into the

trap of starting to believe after Horace had vanished, so it became a

greater probability that the disappearance was related to knowledge of

the theory. Seeing the students vanish had probably set up an emotional

state where complete belief was precipitated.

In the whole series the only improbable part was that so many students

would react in the same short time. That was partly nullified by the

fact that it was a special class, and only high I.Q. students with

excellent records were accepted. They would tend to be somewhat

identical in reaction times.

He straightened up and stared through the windshield at the dark street.

So there it was, the probable mechanism of vanishment. A system was fed

into the conscious mind. The conscious mind accepted it. In due time

that system was transferred down into the matrix that held the person in

this reality or universe. Once there, it made the whole person

_transfer_ to a system where the altered matrix fitted. It might not be

the system pictured in his father's theory. It might be a compromise

system.

_Where_ and _when_ probably had no meaning in relation to the two

systems. That was why, when the shift came, the person vanished

instantly without any strange manifestations of any kind.

Was it reversible? If so, then some of those who had vanished would

reappear eventually.

A sudden, startling thought made Fred sit up straight, his eyes shining

with excitement. So far he had been safe mainly because he habitually

didn't attach belief to anything. His other facet of difference might be

the means of his testing this without real danger of vanishing.

Could he dredge up from the deepest layers of unconscious thought, the

threads leading directly to the matrix that held him in his surroundings

and learn consciously what it was?

A thought. He reflected on it, then decided before he made any decisions

he would explore the other avenue, the one the police had naturally

thought of.

Was there some person or persons unknown in back of the disappearances?

Some non-human, perhaps? It could fit into the same theory of

disappearance. Another universe, beings in that universe. Beings who

perhaps didn't want knowledge of their universe to become known on this

side of the veil.

If so, why hadn't _they_ snatched him too? Maybe they didn't know he

knew about the theory. He'd never talked about it to anyone. But his

father had drilled it into him as a supreme example of the reasons why

belief in anything was a trap.

He shook his head. It didn't seem likely that the disappearances had

been engineered by anyone. They smacked too much of an inner pattern, an

inner mechanism.

So he came back to the other theory. What could he try to accomplish by

exploring into his deepest substratum of thought? The ideal he could aim

for would be conscious transfer into the other system with the assurance

before-hand that he could transfer back again. If he could do that, and

if he could find those who had vanished, maybe he could teach them how

to return.

It was something that might take a long time, he realized. His first

objective was to penetrate deeper into his mind than anyone had ever

consciously gone before. That alone could take a lifetime. Or it might

be accomplished overnight.

How would he begin? Where would he begin? he shrugged. It didn't matter.

He would have to systematically extend his ability to be aware in every

direction, physical and temporal, until he could be conscious of his

individual blood cells if it were possible, and completely and vividly

conscious, at will of every second of his past life. If that didn't lead

him to his objective, it might at least point the way and increase his

ability to reach his goal.

That evening, Fred arrived home to find a stranger seated in the

library. There was the usual moment of clumsiness such encounters

generate, but Fred's mother returned with a tea tray before

self-introductions became necessary. She said, "Mr. Gaard, this is my

son, Fred."

The man smiled easily as Mrs. Grant continued, speaking now to Fred.

"This is Curt Gaard, Fred. I called on him today and what do you think I

discovered. He was a friend--a very old friend--of your father." Mrs.

Grant stopped, a certain inward uncertainty showing through.

Fred stood mute, giving voice to none of the questions which sprang up

in his mind. Curt Gaard, completely at ease, took up the lead. Even as a

feeling of familiarity sprang into Fred's mind, Gaard said, "I _knew_

your father--met him several times--but we weren't as close as your

mother's words might imply."

Then Fred knew. He spoke suddenly. "You're a psychiatrist." The pieces

fell into place. Fred's father had mentioned this man several times, and

the boy knew he was not there by chance--that his mother had contacted

the psychiatrist--this particular one because she too had remembered the

acquaintanceship. For a moment, Fred was annoyed with his mother. Why on

earth had she brought a psychiatrist into this? Then he softened as he

realized she felt it to be to her son's best interests.

"Yes, I'm a psychiatrist," Gaard said. Then, as though he could read

Fred's mind: "Your mother _did_ send for me, but so far as I'm

concerned, it's more than just a professional visit. I knew your father

and liked him. I'd like to be your friend."

"You plan to psychoanalyze me?"

"Don't be so grim about it," Curt Gaard smiled. "Just let's make this a

social visit. There will be plenty of time for other things later.

Perhaps you can drop in at my office."

"Perhaps," Fred said, almost absently. A short time later he excused

himself and went to his room.

* * * * *

"Mrs. Grant?" Mr. Browne said, smiling at the woman behind the screen

door. "I'm Mr. Browne the publisher."

"Browne?" she said. "Oh yes. My hus--husband has mentioned you."

"Favorably, I hope?" Browne was wondering if Dr. Grant had told her of

his decision not to let the book be published.

"Oh yes, very favorably." She frowned. "Which reminds me. He received a

check from you for the advance royalties. I'm sure he didn't cash it

because there was no deposit at the bank that large. I can't find the

check anywhere. He must have had it with him when--"

She had opened the screen door. Browne went in and followed her into the

study. He looked around at the walls of books, almost feeling the

presence of the man whose retreat this had been.

"That's what I've come here to see you about," Browne said. "You see, he

called on me at my office the morning of the day he vanished."

"He did?"

"Yes. I'm going to be quite frank with you. He returned the check to

me."

"Why? He said nothing to me about it."

"I rather imagine he didn't have time. I've waited, knowing you wouldn't

care to discuss business so soon after--" He waited for her reaction.

When she said nothing he continued. "He returned the check and said he

didn't want the book published after all. I couldn't quite understand

his reasons, but they are no longer valid as I see it."

"What were his reasons? This surprises me very much. Just the day before

that he mentioned his book and expressed pleasure that it was being

published."

"The reasons he gave were that the book contained some things that

were--to use his own words--a trifle crackpottish. He thought they might

reflect on him in some way."

"Oh my goodness. He was always doing something like that, Mr. Browne. He

leaned over backwards. Scientific integrity was a fetish with him."

"I haven't read the book," Mr. Browne said. "The reader reported it was

far better than Dr. Grant's first one. That was good enough for me. The

reader is no longer with us." He frowned in irritation at the memory.

"Left us without giving notice. But he was a good man. Excellent

judgment. I'd like to go ahead with the book unless you object."

"I don't know," Mrs. Grant hesitated. "If he didn't want it published--"

"But he's gone now," Browne reminded her.

"I know, but--" She wept softly into a crumpled kerchief.

The publisher remained silent. After a moment she pulled herself

together. "He was always so absent-minded. I was sure he had mislaid the

check. Used it to scribble some problem on. He did that once several

years ago."

Browne reached into his breast-pocket and brought out a long envelope

and extended it toward her.

"I had another check made out for advance royalties," he said, "if you

decide to let me go ahead with the book."

"I don't think I should, Mr. Browne." She withdrew the check from the

envelope and looked at it, her eyebrows lifting at the size of the

figure.

"It's substantially more than the original check," Browne said. "I

thought perhaps you might be in need of money, and I feel confident the

book will sell exceptionally well."

"It is a lot of money," Mrs. Grant said. "But I'm so confused. I wish I

knew what to do."

Browne leaned forward. "Your husband was a great man. I feel it as an

obligation on my part to make public his last work."

Mrs. Grant nodded slowly. "You may be right. I hadn't thought of it that

way."

"And you can undoubtedly use the money," Browne added. "There'll be

more. How much more depends on how the book sells. It may be a steady

income for a few years."

"All right," Mrs. Grant said, making up her mind. "I'll let you publish

it."

"Fine!" Mr. Browne said heartily. "I felt you would. And any time you

need money just call me."

* * * * *

Fred's birthday came in February. He was seventeen now, and the

knowledge filled him with dismay. It had been months since his father

had vanished.

Or _had_ his father vanished? Maybe his memory of those people vanishing

was as wrong as his memory of which way his door opened! To check it he

spent an afternoon in a newspaper office searching back papers until he

found the accounts. He read them all carefully. They were as he

remembered them.

And in him, slowly, grew the realization that he was going to use

someone. He was going to choose someone and try to make that person

disappear. More, he knew that that person was going to be Curt Gaard. He

decided against calling and making an appointment. He would go to the

man's office and put over the sixteen-year-old act.

With a great deal of shyness he confided to the receptionist that Curt

was a very special friend of his mother's. She talked into the

inter-office phone, did a lot of listening and yessing. Finally she told

Fred that Dr. Gaard wanted him to wait a few moments. Then she dialed

an outside number. Fred listened to the clicks and knew it was his home

phone. The psychiatrist was going to talk to his mother. He hadn't

wanted that, but it wouldn't matter materially.

The wait lasted almost half an hour. Then, with heart pounding, Fred was

walking toward the dark walnut door to the inner office. Inside, he

caught a comprehensive glimpse of the rumored couch, luxurious desk and

chairs, thick expensive rug, and an assortment of floor-lamps and oil

paintings. Then the psychiatrist was upon him, heartily welcoming him.

There were time-marking conversational exchanges about school, the hot

rod, and life in general. There was the pause while each sized the other

up.

Then, "I'm glad you dropped in, Fred," Dr. Gaard smiled casually.

"I'm all mixed up," Fred said. "I know something's wrong with me. I

wanted someone to talk to, now that Dad is gone. I thought of you. I

didn't want to bother Mom. Do you really straighten out crazy people?"

"Not exactly," Curt chuckled. "A psychologist finds most of his patients

among people who are just upset about things. They aren't insane. They

just need someone who has experience to help them get their thoughts

straightened out."

"Maybe that's all I need," Fred said. "I don't _think_ I'm crazy."

"Of course you aren't. You're a very healthy-minded young man."

"I don't want Mom to know about this...."

Curt frowned, jotted something down on a notepad. It was, Fred guessed,

a notation to call his mother and warn her to keep quiet.

"Don't worry about your mother. Now tell me, just what seems to be the

trouble?" Curt smiled encouragingly.

"Are you married?" Fred asked with teen-age frankness.

"No," Curt smiled.

"Would you marry my mother?" Fred asked bluntly. "I would like for you

to be my father."

Curt Gaard stared at him a moment. "I really believe you mean that," he

said slowly. "You know, don't you, that it will be two years before she

can be free to marry? Your father can't be declared legally, ah,

departed, for two years."

"No. I didn't know," Fred said, real dismay on his face. He hadn't known

about that. He thought rapidly. "Then can I come live with you? Just

until Mom can marry you?" Inwardly he was enjoying this. And he hoped he

wasn't overdoing it.

"We can't do that," Curt said. "I'll tell you what we can do, though.

I'll invite myself out to dinner tomorrow evening. Don't say anything.

I'll surprise your mother. And we'll see a lot of each other from now

on. Okay?"

Fred nodded. It was definitely okay. He wanted to be present when Curt

Gaard disappeared into thin air, and this way he had a chance.

* * * * *

He left Curt's office highly exhilarated, almost drunk with the emotion

of things working right. It lasted until the following evening when the

doctor showed up and he and Fred's mother put on their little act. Then

his emotions swung the other way. He experienced a reluctance to go

through with his plans. There was too much that was likeable about the

man. And his mother did like him.

"Poor Dad," Fred thought.

After dinner the next evening, Curt kept the conversation on Fred's

father. It was, Fred sensed, the right time to bring up the theory. Curt

would do anything to please him, to draw him out.

But he hesitated. Stretching elaborately, he said, "I'm sleepy. Why

don't you and Mom play Canasta or something?"

"I'm going to be much too busy," his mother said. "I have to finish

proofreading your father's book for the publisher. Mr. Browne is finally

going to print it, and wants it back right away."

"When did that happen?" Fred demanded. "Can I read it?"

"You can read it when it comes out. Now you and Curt go into the study

and leave me alone." She herded them out of the room.

This interlude had served to strengthen Fred's resolve. Alone with the

psychiatrist, he let slip that he knew of a wonderful theory his father

had originated, then tried to cover up.

Curt used flattery. Fred took his cue and slyly bragged that it was a

theory few college professors could understand even, but he understood

it.

More coaxing and he was ready to start in. But his conscience got the

better of him. He balked, and even as he tried to squirm out of it he

realized that it was too late. Dr. Gaard would never rest until the

theory had been told.

"I'll tell you the next time you come," he suggested as a last retreat.

"Tonight," Curt said. "Even if it takes all night. You can miss school

tomorrow." He winked. "I can okay it with the teacher."

"All right," Fred said in sudden crystallization of decision. "But only

if you agree to master every step of it, stopping me until you have."

Curt agreed. He started in.

After half an hour it settled into serious listening on Curt's part, and

pertinent questions that made Fred realize he was dealing with a mind of

more than average keenness.

Fred's mother wandered in occasionally, and out again, without being

noticed by either of them.

An hour passed. Two. The final steps were drawing nearer. At times Curt

was even anticipating some of them. It was midnight when it was

finished. The mind of Curt Gaard held the entire pattern.

Fred couldn't take his eyes off the man's face. The face that was

mirroring the rapid flow of thoughts as it reviewed and attacked every

brick in the structure, finding it solid, and solidly cemented to its

neighbors.

Then he saw a change come over the man's face. He had accepted the

theory. Now he was trying to integrate it into the problem of Fred

Grant. He hadn't yet seen the connection between the theory and the

mysterious disappearances.

And perhaps he wouldn't. If he did he might go the final step and

realize what was going to happen to him. Fred hoped that wouldn't

happen. He didn't want his victim to be conscious of being a victim.

"You _are_ intelligent, Fred," Curt probed, "to be able to master such

an advanced theory." He glanced at his watch. "It's getting pretty late.

I'll tell you what. After school tomorrow drop down to my office. We'll

come out for dinner here together."

"Say! That'd be swell!" Fred enthused. "I'll get right to bed so I can

get enough sleep." He leaped up and called, "Mom! I'm going to bed now."

He winked broadly at Curt to let him know he was getting out of his way

so they could be alone together a few minutes.

And that was that. The die was cast, and all that remained was to try

and use it to make progress, rather than letting it be just another

disappearance that pointed to nothing constructive.

There was no way of telling how fast it would work. The next afternoon

and evening there was little to provide an indication, other than an

occasional look that came over Curt for moments at a time.

A date was made for Saturday. It was to be a picnic in the country. That

meant skipping Friday. Fred violently objected, but Curt and his mother

overrode his objections. So in the end it had to be Saturday, unless

Curt disappeared before then.

He didn't.

* * * * *

But ten minutes before school was out Friday a note was brought into the

classroom from the principal's office. Curt had called to ask Fred to

come to his office directly from school.

Torn between excited anticipation that the psychiatrist had made an

important discovery, and fear that the man would have vanished before he

could get to him, Fred ran from the school building and caught the bus.

At Curt's office the receptionist smiled and told him to go right in.

His sigh of relief was genuine. Curt was sitting at his desk.

"Come in, son," he said.

There were the amenities. "How did school go today?" "Okay." "Anything

happen?" Fred waited impatiently. Then: "I've been thinking a lot about

your father's theory, Fred, and I would like to ask a few questions--if

it won't upset you."

"Of course not!" Fred said.

"Okay, here's a question," Curt said. "Or rather, a statement. You can

answer yes or no. You believe the theory is at the root of the

disappearances, that in some unknown fashion knowing the theory will

cause a person to vanish."

So there it was. Fred debated rapidly in his mind. It might be better to

admit it.

"Yes," he said.

"Hmm. Then let me ask you this. How do you account for the fact that you

know it, and haven't disappeared?"

Fred decided to be completely truthful and see what happened. "It's

because I don't let belief form a part of my thinking, sir. Dad

instilled that in me. With those that disappeared, logic was their

groundwork of belief."

"But you believe knowing the theory caused them to vanish?"

Fred smiled. "I see what you mean. No, I don't. It's just that no other

alternative seems probable, so...."

"So you work with the one that does," Curt said, nodding. "All right,

let's work with it for the moment. You have probably done some thinking

on what mechanism might be involved in the process of vanishing. Would

you care to tell me about it?"

"There's no reason why not, sir. It takes time for conscious beliefs to

sink into the subconscious and integrate there. The time varies with the

person and the emotions involved."

"That makes sense," Curt said, nodding.

"I postulated that down underneath even the subconscious, at the very

roots of being, is what I named the basic thought matrix. In order for

us to be here in this existence at all it must have a certain form.

Change that form and, presto, the person slips out of this existence,

perhaps into another."

"I see." Curt drummed his fingers on the desk for a long minute. "I

see," he repeated. "Has it occurred to you that you have already

rejected your theory? It's quite obvious you have, you know."

"How is it obvious?" Fred asked, wondering what Curt meant.

"Because you told me the theory. You wouldn't have, of course, if you

believed it would cause me to vanish like the others."

Fred opened and closed his mouth several times, unable to cope with

this. It was unexpected.

"We've gotten to the root of your trouble," Curt went on. "It was a real

trouble, to you. In a few months you will look back on it and marvel at

it. Right now it seems real. You feel that somewhere your father still

exists. You would like to go to him, or perhaps bring him back. Believe

me, such mysterious vanishings aren't uncommon. The history of the world

is full of such incidents. In some cases whole groups have vanished.

Authenticated cases. In southeast Asia the people of an entire city of

over a million inhabitants vanished overnight. In the last century an

entire trainload of people, including the train, vanished while going

from one city to another a few miles away. And there have been

vanishments with reappearances, too. In England there was an old woman

who suddenly vanished before the eyes of her family. At the same instant

she reappeared in a room in London, miles away, in front of other

people. Did she know your father's theory? Did the train that vanished

know that theory?" Curt was smiling. "No. You see, it's something

unrelated to your father's theory."

Fred was nodding. "You may be right," he said. "I didn't know about

those."

"You may go now, son," Curt said. "I'll be out around eleven o'clock in

the morning."

Fred rose quickly. "Okay, Curt," he said. "I'll see you." He hurried

out. It was too much of an effort to hide the sudden trembling. He

hadn't known about other cases of vanishing. They provided data to

expand the whole thing, while not in the slightest detracting from the

validity of anything else.

And if the talk had been prolonged much more Curt would have inevitably

tumbled to his motive for telling him the theory.

* * * * *

Promptly at eleven Curt arrived. Fred's mother had already prepared the

large basket of food. There were ten minutes of last-minute bustle, then

they were off, with Curt skillfully tooling his Cadillac in and out of

traffic until they were on the open highway.

"I know just the place," he told them. "Woods, meadow, brook. Even a

couple of cows." And he did. When they arrived shortly before

twelve-thirty it was all that.

Fred relaxed as the car came to a stop. Every second of the trip he had

been ready to seize the wheel and keep the car from crashing if Curt

vanished.

"Still a little nervous?" Curt asked him as they got out.

"No. No, of course not!" Fred said.

Curt didn't pursue the subject. Instead, he became something utterly

different than he had been before, a carefree thoroughly likeable man,

full of humor.

Fred began to regret that he had chosen him as his victim. He began to

hope that the process might not be automatic, that Curt wouldn't vanish.

But he stayed close to him and listened to his every word and watched

his face as much as he dared without staring, so that if the moment came

he could get whatever there was to get of value from it.

For the first time in years his mother began to be carefree. She even

joked back at Curt occasionally, something she had never done with

Martin in Fred's memory. Her joking was clumsy and uncertain. Fred

laughed uproariously to encourage her and to hide his uncomfortable

feeling.

"Oh, I haven't felt so good in ages," she said when they were seated

around the tablecloth spread with sandwiches and salads and cakes. "It's

wonderful getting out like this. We'll have to do it often."

"We will," Curt said. "At least once a week."

Fred's mother picked up a sandwich. She started to raise it to her

mouth. She was smiling at Curt and about to say something to him. Both

Curt and Fred were watching her.

Abruptly she wasn't there. The sandwich seemed to remain stationary for

a long second. Then it dropped to the tablecloth.

Curt was holding a paper cup filled with hot coffee. His hand

constricted. The cup collapsed, spilling steaming coffee over his legs.

Fred stared at the space his mother had just occupied. Abruptly he

squawked, "No!" He turned accusing eyes on Curt. "You told her!"

Something seemed to go out of the man. He seemed to become visibly

smaller. "Yes," he whispered, "I told her."

Fred was crying. "But you shouldn't have," he sobbed. "I told you

because I wanted you to vanish. I didn't want her to, and now she has.

And nothing happened that I could use."

Curt blinked at him, absorbing this new bit of information. "You wanted

_me_ to vanish?" he echoed. "Yes, I can see that now. I didn't know. It

seemed too absurd. I thought you were just imagining things. Yes, I went

out while you were at school and spent the whole morning teaching her

every step. It was fairly easy. We had planned on coaxing you to explain

it to her. Knowing it ahead of time she could pretend to grasp it that

much more easily. We were planning on coaxing you into a more social

relationship. Actually, she had already read the theory in your father's

book she was reading for the publisher." A glassy look came into his

eyes. "The book. If the theory is at the root of the disappearances the

book shouldn't be published. Yes, by God. That's what your father was

driving at. Your mother told me the publisher had told her your father

tried to get him not to publish it."

"The book has the theory in it?" Fred said. "It mustn't get published.

Why--thousands of people would read it and vanish. We've got to stop

them!"

Curt was shaking his head in bewilderment. "But we can't be sure. It

must be something else, though what I don't know."

"No," Fred said bitterly.

There was a long silence. Curt broke it by saying, "What did you expect

to accomplish by my vanishing?"

Fred told him of Horace's shouting to his wife, "Ethel! I've got it!",

and the others seeming to have a flash of divination or insight just

before they vanished.

"I wanted," he explained dully, "to be with you when it happened, in the

hopes I could get something more than I have to go on. In that way I

might be able to find out something so I could bring my father back. And

Mom." He began to cry.

"I see," Curt said, calm and a little subdued. "It's possible that may

come. After what I've seen happen I can admit it as a possibility."

"Then you will make every effort to tell me?" Fred asked.
