The United States Submarine Ambitious Brill slid smoothly into her berth in the Brooklyn Navy Yard after far too many weeks at sea, as far as her crew were concerned. After all the necessary preliminaries had been waded through, the majority of that happy crew went ashore to enjoy a well-earned and long-anticipated leave in the depths of the brick-and-glass canyons of Gomorrah-on-the-Hudson.

The trip had been uneventful, in so far as nothing really dangerous or exciting had happened. Nothing, indeed, that could even be called out-of-the-way--except that there was more brass aboard than usual, and that the entire trip had been made underwater with the exception of one surfacing for a careful position check, in order to make sure that the ship’s instruments gave the same position as the stars gave. They had. All was well.

That is not to say that the crew of the Ambitious Brill were entirely satisfied in their own minds about certain questions that had been puzzling them. They weren’t. But they knew better than to ask questions, even among themselves. And they said nothing whatever when they got ashore. But even the novices among submarine crews know that while the nuclear-powered subs like George Washington, Patrick Henry, or Benjamin Franklin are perfectly capable of circumnavigating the globe without coming up for air, such performances are decidedly rare in a presumably Diesel-electric vessel such as the U.S.S. Ambitious Brill. And those few members of the crew who had seen what went on in the battery room were the most secretive and the most puzzled of all. They, and they alone, knew that some of the cells of the big battery that drove the ship’s electric motors had been removed to make room for a big, steel-clad box hardly bigger than a foot locker, and that the rest of the battery hadn’t been used at all.

With no one aboard but the duty watch, and no one in the battery room at all, Captain Dean Lacey felt no compunction whatever in saying, as he gazed at the steel-clad, sealed box: “What a battery!”

The vessel’s captain, Lieutenant Commander Newton Wayne, looked up from the box into the Pentagon representative’s face. “Yes, sir, it is.” His voice sounded as though his brain were trying to catch up with it and hadn’t quite succeeded. “This certainly puts us well ahead of the Russians.”

Captain Lacey returned the look. “How right you are, commander. This means we can convert every ship in the Navy in a tenth the time we had figured.”

Then they both looked at the third man, a civilian.

He nodded complacently. “And at a tenth the cost, gentlemen,” he said mildly. “North American Carbide & Metals can produce these units cheaply, and at a rate that will enable us to convert every ship in the Navy within the year.”

Captain Lacey shot a glance at Lieutenant Commander Wayne. “All this is strictly Top Secret you understand.”

“Yes, sir; I understand,” said Wayne.

“Very well.” He looked back at the civilian. “Are we ready, Mr. Thorn?”

“Anytime you are, captain,” the civilian said.

“Fine. You have your instructions, commander. Carry on.”

“Aye, aye, sir,” said Lieutenant Commander Wayne.

A little less than an hour later, Captain Lacey and Mr. Thorn were in the dining room of one of the most exclusive clubs in New York. Most clubs in New York are labeled as “exclusive” because they exclude certain people who do not measure up to their standards of wealth. A man who makes less than, say, one hundred thousand dollars a year would not even qualify for scrutiny by the Executive Committee. There is one club in Manhattan which reaches what is probably close to the limit on that kind of exclusiveness: Members must be white, Anglo-Saxon, Protestant Americans who can trace their ancestry as white, Anglo-Saxon, Protestant Americans back at least as far as the American Revolution without exception, and who are worth at least ten millions, and who can show that the fortune came into the family at least four generations back. No others need apply. It is said that this club is not a very congenial one because the two members hate each other.

The club in which Lacey and Thorn ate their dinner is not of that sort. It is composed of military and naval officers and certain civilian career men in the United States Government. These men are professionals. Not one of them would ever resign from government service. They are dedicated, heart, body, and soul to the United States of America. The life, public and private, of every man Jack of them is an open book to every other member. Of the three living men who have held--and the one who at present holds--the title of President of the United States, only one was a member of the club before he held that high office.

As an exclusive club, they rank well above England’s House of Peers and just a shade below the College of Cardinals of the Roman Catholic Church.

Captain Lacey was a member. Mr. Richard Thorn was not, but he was among those few who qualify to be invited as guests. The carefully guarded precincts of the club were among the very few in which these two men could talk openly and at ease.

After the duck came the brandy, both men having declined dessert. And over the brandy--that ultra-rare Five Star Hennessy which is procurable only by certain people and is believed by many not to exist at all--Captain Lacey finally asked the question that had been bothering him for so long.

“Thorn,” he said, “three months ago that battery didn’t exist. I know it and you know it. Who was the genius who invented it?”

Thorn smiled, and there was a subtle wryness in the smile. “Genius is the word, I suppose. Now that the contracts with the Navy have been signed, I can give you the straight story. But you’re wrong in saying that the thing didn’t exist three months ago. It did. We just didn’t know about it, that’s all.”

Lacey raised his bushy, iron-gray eyebrows. “Oh? And how did it come to the attention of North American Carbide & Metals?”

Thorn puffed out his cheeks and blew out his breath softly before he began talking, as though he were composing his beginning sentences in his mind. Then he said: “The first I heard about it was four months ago. Considering what’s happened since then, it seems a lot longer.” He inhaled deeply from his brandy snifter before continuing. “As head of the development labs for NAC&M, I was asked to take part as a witness to a demonstration that had been arranged through some of the other officers of the company. It was to take place out on Salt Lake Flats, where--”

It was to take place out on Salt Lake Flats, where there was no chance of hanky-panky. Richard Thorn--who held a Ph.D. from one of the finest technological colleges in the East, but who preferred to be addressed as “Mister”--was in a bad mood. He had flown all the way out to Salt Lake City after being given only a few hours notice, and then had been bundled into a jeep furnished by the local sales office of NAC&M and scooted off to the blinding gray-white glare of the Salt Flats. It was hot and it was much too sunshiny for Thorn. But he had made the arrangements for the test himself, so he couldn’t argue or complain too loudly. He could only complain mildly to himself that the business office of the company, which had made the final arrangements, had, in his opinion, been a little too much in a hurry to get the thing over with. Thorn himself felt that the test could have at least waited until the weather cooled off. The only consolation he had was that, out here, the humidity was so low that he could stay fairly comfortable in spite of the heat as long as there was plenty of drinking water. He had made sure to bring plenty.

The cavalcade of vehicles arrived at the appointed spot--umpteen miles from nowhere--and pulled up in a circle.

Thorn climbed out wearily and saw the man who called himself Sorensen climb out of the second jeep.

From the first time he had seen him, Thorn had tagged Sorensen as an Angry Old Man. Not that he was really getting old; he was still somewhere on the brisk side of fifty. But he wore a perpetual scowl on his face that looked as though it had been etched there by too many years of frustration, and his voice always seemed to have an acid edge to it, like that of an old man who has decided, after decades of observation, that all men are fools. And yet Thorn thought he occasionally caught a glimpse of mocking humor in the pale blue eyes. He was lean and rather tall, with white hair that still showed traces of blond, and he looked as Scandinavian as his name sounded. His accent was pure Minnesota American.

As he climbed out of the jeep, Sorensen brought with him the Black Suitcase.

Ever since he had first seen it, Thorn had thought of it as “the Black Suitcase,” and after he had seen some of the preliminary tests, he had subconsciously put capitals to the words. But Richard Thorn was no fool. Too many men had been suckered before, and he, Richard Thorn, did not intend to be another sucker, no matter how impressed he might be by the performance of an invention.

If this was a con game, it was going to have to be a good one to get by Richard Thorn, Ph.D.

He walked across the few feet of hard, salt-white ground that separated him from Sorensen standing beside the second jeep with the Black Suitcase in his hand. It was obvious to anyone who watched the way Sorensen handled the thing that it was heavy--seventy-five pounds or better.

“Need any help?” Thorn asked, knowing what the answer would be.

“Nope,” Sorensen said. “I can handle it.”

The suitcase wasn’t really black. It was a dark cordovan brown, made even darker by long usage, which had added oily stains to the well-used leather. But Thorn thought of it as the Black Suitcase simply because it was the perfect example of the proverbial Little Black Box--the box that Did Things. As a test question in an examination, the Little Black Box performs a useful function. The examiner draws a symbolic electronic circuit. Somewhere in the circuit, instead of drawing the component that is supposed to be there, he draws a Little Black Box. Then he defines the wave-form, voltage, and amperage entering the circuit and defines whatever is coming out. Question: What is in the Little Black Box?

Except in the simplest of cases, there is never an absolute answer. The question is counted as correct if the student puts into the Little Black Box a component or subcircuit which will produce the effect desired. The value of the answer depends on the simplicity and relative controllability of the component drawn in the place of the Little Black Box.

Sorensen’s Black Suitcase was still a problem to Thorn. He couldn’t quite figure out what was in it.

“Hotter’n Billy Blue Blazes!” Sorensen said as he put the Black Suitcase down on the gleaming white ground. He grinned a little, which dispelled for a moment his Angry Old Man expression, and said: “You ready to go, Mr. Thorn?”

“I’m ready any time you are,” Thorn said grumpily.

Sorensen looked at the NAC&M scientist sideways. “You don’t sound any happier’n I am, Mr. Thorn.”

Thorn looked at him and thought he could see that flash of odd humor in his light blue eyes. Thorn exhaled a heavy breath. “I’m no happier than you are to be out in this heat. Let’s get on with it.”

Sorensen’s chuckle sounded so out of place that Thorn was almost startled. “You know the difference between you and me, Mr. Thorn?” Sorensen asked. He didn’t wait for an answer. “You think this test is probably a waste of time. Me, on the other hand, I know it is.”

“Let’s get on with it,” Thorn repeated.

It took two hours to set up the equipment, in spite of the fact that a lot of the circuits had been prefabricated before the caravan had come out from Salt Lake City. But Richard Thorn wanted to make certain that all his data was both correct and recorded. Sorensen had nothing to do but watch. He had no hand in setting up the equipment. He had brought the Black Suitcase, and that was all he was going to be allowed to do.

From the top of the Black Suitcase projected two one-inch copper electrodes, fourteen inches apart. The North American Carbide & Metals technicians set up the circuits that were connected to the electrodes without any help from Sorensen.

But just before they started to work, Sorensen said: “There’s just one thing I think you ought to warn those men about, Mr. Thorn.”

“What’s that?” Thorn asked.

“If any of ‘em tries to open that suitcase, they’re likely to get blown sky high. And I don’t want ‘em getting funny with me, either.”

He had his hand in his trouser pocket, and Thorn was suddenly quite certain that the man was holding a revolver. He could see the outlines against the cloth.

Thorn sighed. “Don’t worry, Mr. Sorensen. We don’t have any ulterior designs on your invention.” He did not add that the investigators of NAC&M had already assumed that anyone who was asking one million dollars for an invention which was, in effect, a pig in a poke, would be expected to take drastic methods to protect his gadget. But there would be no point in telling Sorensen that his protective efforts had already been anticipated and that the technicians had already been warned against touching the Black Suitcase any more than necessary to connect the leads. Giving Sorensen that information might make him even more touchy.

Thorn only hoped that the bomb, or whatever it was that Sorensen had put in the suitcase, was well built, properly fused, and provided with adequate safeties.

When everything was set up, Sorensen walked over to his device and turned it on by shoving the blade of a heavy-duty switch into place. “O.K.,” he said.

One of the technicians began flipping other switches, and a bank of ordinary incandescent light bulbs came on, four at a time. Finally there were one hundred of them burning, each one a hundred-watt bulb that glowed brightly but did not appear to be contributing much to the general brightness of the Utah sun. The technicians checked their recording voltmeters and ammeters and reported that, sure enough, some ten kilowatts of power at a little less than one hundred fifteen volts D.C. was coming from the Black Suitcase.

Sorensen and Thorn sat in the tent which had been erected to ward off the sun’s rays. They watched the lights shine.

One of the technicians came in, wiping his forehead with a big blue bandana. “Well, there she goes. Mr. Sorensen, if that thing is dangerous, hadn’t we better back off a little way from it?”

“It isn’t dangerous,” Sorensen said. “Nothing’s going to happen.”

The technician looked unhappy. “Then I don’t see why we couldn’t’ve tested the thing back in the shop. Would’ve been a lot easier there. To say nothing of more comfortable.”

Thorn lit a cigarette in silence.

Sorensen nodded and said, “Yes, Mr. Siegel, it would’ve been.”

Siegel sat down on one of the camp stools and lit a cigarette. “Mr. Sorensen,” he asked in all innocence, “have you got a patent on that battery?”

The humorous glint returned to Sorensen’s eyes as he said, “Nope. I didn’t patent the battery in that suitcase. That’s why I don’t want anybody fooling around with it.”

“How come you don’t patent it?” Siegel asked. “Nobody could steal it if you patented it.”

“Couldn’t they?” Sorensen asked with a touch of acid in his voice. “Do you know anything about batteries, Mr. Siegel?”

“A little. I’m not an expert on ‘em, or anything like that. I’m an electrician. But I know a little bit about ‘em.”

Sorensen nodded. “Then you should know, Mr. Siegel, that battery-making is an art, not a science. You don’t just stick a couple of electrodes into a solution of electrolyte and consider that your work is done. With the same two metals and the same electrolyte, you could make batteries that would run the gamut from terrible to excellent. Some of ‘em, maybe, wouldn’t hold a charge more than an hour, while others would have a shelf-life, fully charged, of as much as a year. Batteries don’t work according to theory. If they did, potassium chlorate would be a better depolarizer than manganese dioxide, instead of the other way around. What you get out of a voltaic cell depends on the composition and strength of the electrolyte, the kind of depolarizer used, the shape of the electrodes, the kind of surface they have, their arrangement and spacing, and a hundred other little things.”

“I’ve heard that,” Siegel said.

[Illustration]

Thorn smoked in silence. He had heard Sorensen’s arguments before. Sorensen didn’t mind discussing his battery in the abstract, but he was awfully close-mouthed when it came to talking about it in concrete terms. He would talk about batteries-in-general, but not about this-battery-in-particular.

Not that Thorn blamed him in the least. Sorensen was absolutely correct in his statements about the state of the art of making voltaic cells. If Sorensen had something new--and Thorn was almost totally convinced that he did--then he was playing it smart by not trying to patent it.

“Now then,” Sorensen went on, “let’s suppose that my battery is made up of lead and lead dioxide plates in a sulfuric acid solution, except that I’ve added a couple of trifling things and made a few small changes in the physical structure of the plates. I’m not saying that’s what the battery is, mind you; I’m saying ‘suppose’.”

“O.K., suppose,” said Siegel. “Couldn’t you patent it?”

“What’s to patent? The Pb-PbO2-H2SO_4 cell is about half as old as the United States Patent Office itself. Can’t patent that. Copper oxide, maybe, as a depolarizer? Old hat; can’t patent that. Laminated plates, maybe? Nope. Can’t patent that, either.”
