For two months, Ralson lived in a comer of Grant's office, and Grant lived with him. Gridwork had been built up before the windows, wooden furniture was removed and upholstered sofas brought in. Ralson did his thinking on the couch and his calculating on a desk pad atop a hassock.
The "Do Not Enter" was a permanent fixture outside the office. Meals were left outside. The adjoining men's room was marked off for private use and the door between it and the office removed. Grant switched to an electric razor. He made certain that Ralson took sleeping pills each night and waited till the other slept before sleeping himself.
And always reports were brought to Ralson. He read them while Grant watched and tried to seem not to watch.
Then Ralson would let them drop and stare at the ceiling, with one hand shading his eyes.
"Anything?" asked Grant. 1 Ralson shook his head from side to side.
'; Grant said, "Look, I'll clear the building during the swing shift. It's important that you see some of the experimental jigs we've been setting 1 UP •" , They did so, wandering through the lighted, empty buildings like drifting
* ghosts, hand in hand. Always hand in hand. Grant's grip was tight. But after
each trip, Ralson would still shake his head from side to side. 1 Half a dozen times he would begin writing; each time there would be a ; few scrawls and then he would kick the hassock over on its side.
Until, finally, he began writing once again and covered half a page rapidly. Automatically, Grant approached. Ralson looked up, covering the sheet of paper with a trembling hand. He said, "Call Blaustein." "What?"
"I said, 'Call Blaustein.' Get him here. Now!" Grant moved to the telephone.
Ralson was writing rapidly now, stopping only to brush wildly at his forehead with the back of a hand. It came away wet. He looked up and his voice was cracked, "Is he coming?" Grant looked worried. "He isn't at his office."
"Get him at his home. Get him wherever he is. Use that telephone. Don't play with it."
Grant used it; and Ralson pulled another sheet toward himself.
Five minutes later, Grant said, "He's coming. What's wrong? You're looking sick."
Ralson could speak only thickly, "No time- Can't talk-"
He was writing, scribbling, scrawling, shakily diagraming. It was as though he were driving his hands, fighting it.
"Dictatp!" urged Grant. "I'll write."
Ralson shook him off. His words were unintelligible. He held his wrist with his other hand, shoving it as though it were a piece of wood, and then he collapsed over the papers.
Grant edged them out from under and laid Ralson down on the couch. He hovered over him restlessly and hopelessly until Blaustein arrived.
Blaustein took one look. "What happened?"
Grant said, "I think he's alive," but by that time Blaustein had verified that for himself, and Grant told him what had happened.
Blaustein used a hypodermic and they waited. Ralson's eyes were blank when they opened. He moaned.
Blaustein leaned close. "Ralson."
Ralson's hands reached out blindly and clutched at the psychiatrist. "Doc. Take me back."
"I will. Now. It is that you have the force field worked out, no?"
"It's on the papers. Grant, it's on the papers."
Grant had them and was leafing through them dubiously. Ralson said, weakly, "It's not all there. It's all I can write. You'll have to make it out of that. Take me back, Doc!"
"Wait," said Grant. He whispered urgently to Blaustein. "Can't you leave him here till we test this thing? I can't make out what most of this is. The writing is illegible. Ask him what makes him think this will work."
"Ask him?" said Blaustein, gentry. "Isn't he the one who always knows?"
"Ask me, anyway," said Ralson, overhearing from where he lay on the couch. His eyes were suddenly wide and blazing.
They turned to him.
He said, "They don't want a force field. They! The experimenters! As long as I had no true grasp, things remained as they were. But I hadn't followed up that thought-that thought which is there in the papers-I hadn't followed it up for thirty seconds before I felt ... I felt- Doctor-"
Blaustein said, "What is it?"
Ralson was whispering again, "I'm deeper in the penicillin. I could feel myself plunging in and in, the further I went with that. I've never been in ... so deep. That's how I knew I was right. Take me away."
Blaustein straightened. "I'll have to take him away, Grant. There's no alternative. If you can make out what he's written, that's it. If you can't
make it out, I can't help you. That man can do no more work in his field
without dying, do you understand?"
"But," said Grant, "he's dying of something imaginary."
"All right. Say that he is. But he will be really dead just the same, no?"
Ralson was unconscious again and heard nothing of this. Grant looked at
him somberly, then said, "Well, take him away, then."
Ten of the top men at the Institute watched glumly as slide after slide filled the illuminated screen. Grant faced them, expression hard and frowning.
He said, "I think the idea is simple enough. You're mathematicians and you're engineers. The scrawl may seem illegible, but it was done with meaning behind it. That meaning must somehow remain in the writing, distorted though it is. The first page is clear enough. It should be a good lead. Each one of you will look at every page over and over again. You're going to put down every possible version of each page as it seems it might be. You will work independently. I want no consultations."
One of them said, "How do you know it means anything, Grant?"
"Because those are Ralson's notes."
"Ralson! I thought he was-"
"You thought he was sick," said Grant. He had to shout over the rising hum of conversation. "I know. He is. That's the writing of a man who was nearly dead. It's all we'll ever get from Ralson, any more. Somewhere in that scrawl is the answer to the force field problem. If we can't find it, we may have to spend ten years looking for it elsewhere."
They bent to their work. The night passed. Two nights passed. Three nights-
Grant looked at the results. He shook his head. "I'll take your word for it that it is all self-consistent. I can't say I understand it."
Lowe, who, in the absence of Ralson, would readily have been rated the best nuclear engineer at the Institute, shrugged. "It's not exactly clear to me. If it works, he hasn't explained why."
"He had no time to explain. Can you build the generator as he describes it?"
"I could try."
"Would you look at all the other versions of the pages?"
"The others are definitely not self-consistent."
"Would you double-check?"
"Sure."
"And could you start construction anyway?"
"I'll get the shop started. But I tell you frankly that I'm pessimistic."
"I know. So am I." • i >",i, ...
The thing grew. Hal Ross, Senior Mechanic, was put in charge of the actual construction, and he stopped sleeping. At any hour of the day or night, he could be found at it, scratching his bald head.
He asked questions only once, "What is it, Dr. Lowe? Never saw anything like it? What's it supposed to do?"
Lowe said, "You know where you are, Ross. You know we don't ask questions here. Don't ask again."
Ross did not ask again. He was known to dislike the structure that was being built. He called it ugly and unnatural. But he stayed at it.
Blaustein called one day.
Grant said, "How's Ralson?"
"Not good. He wants to attend the testing of the Field Projector he designed."
Grant hesitated, "I suppose we should. It's his after all."
"I would have to come with him."
Grant looked unhappier. "It might be dangerous, you know. Even in a pilot test, we'd be playing with tremendous energies."
Blaustein said, "No more dangerous for u
s than for you."
"Very well. The list of observers will have to be cleared through the Commission and the F.B.I., but I'll put you in."
Blaustein looked about him. The field projector squatted in the very center of the huge testing laboratory, but all else had been cleared. There was no visible connection with the plutonium pile which served as energy-source, but from what the psychiatrist heard in scraps about him-he knew better than to ask Ralson-the connection was from beneath.
At first, the observers had circled the machine, talking in incomprehen-sibles, but they were drifting away now. The gallery was filling up. There were at least three men in generals' uniforms on the other side, and a real coterie of lower-scale military. Blaustein chose an unoccupied portion of the railing; for Ralson's sake, most of all.
He said, "Do you still think you would like to stay?"
It was warm enough within the laboratory, but Ralson was in his coat, with his collar turned up. It made little difference, Blaustein felt. He doubted that any of Ralson's former acquaintances would now recognize him.
Ralson said, "I'll stay."
Blaustein was pleased. He wanted to see the test. He turned again at a new voice.
"Hello, Dr. Blaustein."
For a minute, Blaustein did not place him, then he said, "Ah, Inspector Darrity. What are you doing here?"
"Just what you would suppose." He indicated the watchers. "There isn't
any way you can weed them out so that you can be sure there won't be any mistakes. I once stood as near to Klaus Fuchs as I am standing to you." He tossed his pocketknife into the air and retrieved it with a dexterous motion.
"Ah, yes. Where shall one find perfect security? What man can trust even his own unconscious? And you will now stand near to me, no?"
"Might as well." Darrity smiled. "You were very anxious to get in here, weren't you?"
"Not for myself, Inspector. And would you put away the knife, please."
Darrity turned in surprise in the direction of Blaustein's gentle head-gesture. He put his knife away and looked at Blaustein's companion for the second time. He whistled softly.
He said, "Hello, Dr. Ralson."
Ralson croaked, "Hello."
Blaustein was not surprised at Darrity's reaction. Ralson had lost twenty pounds since returning to the sanatorium. His face was yellow and wrinkled; the face of a man who had suddenly become sixty.
Blaustein said, "Will the test be starting soon?"
Darrity said, "It looks as if they're starting now."
He turned and leaned on the rail. Blaustein took Ralson's elbow and began leading him away, but Darrity said, softly, "Stay here, Doc. I don't want you wandering about."
Blaustein looked across the laboratory. Men were standing about with the uncomfortable air of having turned half to stone. He could recognize Grant, tall and gaunt, moving his hand slowly to light a cigarette, then changing his mind and putting lighter and cigarette in his pocket. The young men at the control panels waited tensely.
Then there was a low humming and the faint smell of ozone filled the air.
Ralson said harshly, "Look!"
Blaustein and Darrity looked along the pointing finger. The projector seemed to flicker. It was as though there were heated air rising between it and them. An iron ball came swinging down pendulum fashion and passed through the flickering area.
"It slowed up, no?" said Blaustein, excitedly.
Ralson nodded. "They're measuring the height of rise on the other side to calculate the loss of momentum. Fools! I said it would work." He was speaking with obvious difficulty.
Blaustein said, "Just watch, Dr. Ralson. I would not allow myself to grow needlessly excited."
The pendulum was stopped in its swinging, drawn up. The flickering about the projector became a little more intense and the iron sphere arced down once again.
Over and over again, and each time the sphere's motion was slowed with more of a jerk. It made a clearly audible sound as it struck the flicker. And
eventually, it bounced. First, soggily, as though it hit putty, and then ring-ingly, as though it hit steel, so that the noise filled the place.
They drew back the pendulum bob and used it no longer. The projector could hardly be seen behind the haze that surrounded it.
Grant gave an order and the odor of ozone was suddenly sharp and pungent. There was a cry from the assembled observers; each one exclaiming to his neighbor. A dozen fingers were pointing.
Blaustein leaned over the railing, as excited as the rest. Where the projector had been, there was now only a huge semi-globular mirror. It was perfectly and beautifully clear. He could see himself in it, a small man standing on a small balcony that curved up on each side. He could see the fluorescent lights reflected in spots of glowing illumination. It was wonderfully sharp.
He was shouting, "Look, Ralson. It is reflecting energy. It ie reflecting light waves like a mirror. Ralson-"
He turned, "Ralson! Inspector, where is Ralson?"
"What?" Darrity whirled. "I haven't seen him."
He looked about, wildly. "Well, he won't get away. No way of getting out of here now. You take the other side." And then he clapped hand to thigh, fumbled for a moment in his pocket, and said, "My knife is gone."
Bkustein found him. He was inside the small office belonging to Hal Ross. It led off the balcony, but under the circumstances, of course, it had been deserted. Ross himself was not even an observer. A senior mechanic need not observe. But his office would do very well for the final end of the long fight against suicide.
Blaustein stood in the doorway for a sick moment, then turned. He caught Darrity's eye as the latter emerged from a similar office a hundred feet down the balcony. He beckoned, and Darrity came at a run.
Dr. Grant was trembling with excitement. He had taken two puffs at each of two cigarettes and trodden each underfoot thereafter. He was fumbling with the third now.
He was saying, "This is better than any of us could possibly have hoped. We'll have the gunfire test tomorrow. I'm sure of the result now, but we've planned it; we'll go through with it. We'll skip the small arms and start with the bazooka levels. Or maybe not. It might be necessary to construct a special testing structure to take care of the ricochet problem."
He discarded his third cigarette.
A general said, "We'd have to try a literal atom-bombing, of course."
"Naturally. Arrangements have already been made to build a mock-city at Eniwetok. We could build a generator on the spot and drop the bomb. There'd be animals inside."
"And you really think if we set up a field in full power it would hold the bomb?"
"It's not just that, general. There'd be no noticeable field at all until the
bomb is dropped. The radiation of the plutonium would have to energize the field before explosion. As we did here in the last step. That's the essence of it all."
"You know," said a Princeton professor, "I see disadvantages, too. When the field is on full, anything it protects is in total darkness, as far as the sun is concerned. Besides that, it strikes me that the enemy can adopt the practice of dropping harmless radioactive missiles to set off the field at frequent intervals. It would have nuisance value and be a considerable drain on our pile as well."
"Nuisances," said Grant, "can be survived. These difficulties will be met eventually, I'm sure, now that the main problem has been solved."
The British observer had worked his way toward Grant and was shaking hands. He said, "I feel better about London already. I cannot help but wish your government would allow me to see the complete plans. What I have seen strikes me as completely ingenious. It seems obvious now, of course, but how did anyone ever come to think of it?"
Grant smiled. "That question has been asked before with reference to Dr. Ralson's devices-"
He turned at the touch of a hand upon his shoulder. "Dr. Blaustein! I had nearly forgotten. Here, I want to talk to you."
He dragged the small psychiatrist t
o one side and hissed in his ear, "Listen, can you persuade Ralson to be introduced to these people? This is his triumph."
Blaustein said, "Ralson is dead." i, "What'"
"Can you leave these people for a time?" 5 "Yes . . . yes- Gentlemen, you will excuse me for a few minutes?"
He hurried off with Blaustein.
The Federal men had already taken over. Unobtrusively, they barred the doorway to Ross's office. Outside there were the milling crowd discussing the answer to Alamogordo that they had just witnessed. Inside, unknown to them, was the death of the answerer. The G-man barrier divided to allow Grant and Blaustein to enter. It closed behind them again.
For a moment, Grant raised the sheet. He said, "He looks peaceful." i "I would say-happy," said Blaustein.
• Darrity said, colorlessly, "The suicide weapon was my own knife. It was !my negligence; it will be reported as such."
• "No, no," said Blaustein, "that would be useless. He was my patient and I am responsible. In any case, he would not have lived another week. Since he invented the projector, he was a dying man."
Grant said, "How much of this has to be placed in the Federal files? Can't we forget all about his madness?"
"I'm afraid not, Dr. Grant," said Darrity.
"I have told him the whole story," said Blaustein, sadly.
Grant looked from one to the other. "I'll speak to the Director. I'll go to the President, if necessary. I don't see that there need be any mention of suicide or of madness. He'll get full publicity as inventor of the field projector. It's the least we can do for him." His teeth were gritting.
Blaustein said, "He left a note."
"A note?"
Darrity handed him a sheet of paper and said, "Suicides almost always do. This is one reason the doctor told me about what really killed Ralson."
The note was addressed to Blaustein and it went:
"The projector works; I knew it would. The bargain is done. You've got it and you don't need me any more. So I'll go. You needn't worry about the human race, Doc. You were right. They've bred us too long; they've taken too many chances. We're out of the culture now and they won't be able to stop us. I know. That's all I can say. I know."
