Telepathy, then, if it existed at all, had to be tunable. Carl then applied his analogy. Crystals identical in structure resonate at the same frequency. Humans identical in structure do exist: they are called identical twins. For two years Master Carl had spent most of his free time locating, persuading and testing pairs of identical twins. It took two years, and no more, because that was how long it took him to find three hundred and twenty-six pairs; and three hundred and twenty-six was the number the chi-square law gave as the minimum universe in which a statistical sampling could be regarded as conclusive. When the three hundred and twenty-sixth twin had failed to secure significantly more than chance correlation with the card symbols viewed by his sibling, Carl had closed out the experiment at once.
When the two-year job was ended Carl was not angry, but he was also not hopeful. It did not occur to him to go on to a three hundred and twenty-seventh set. He did, however, permit himself to turn at once to investigating other aspects of what had once been called psionics.
Precognition he eliminated on logical grounds; clairvoyance he pondered over for several months before deciding that, like the conjecture that flying saucers were of extraterrestrial origin, it offered too few opportunities for experimental verification to be an attractive study. Hexing he ruled out as necessarily involving either telepathy or clairvoyance. It was not the cases in which the sufferer knew he was hexed that offered a problem; simple suggestion could account for most of those; a man who saw the wax doll with the pins in it, or was told by the ju-ju man that his toenails were being roasted, might very easily sicken and die out of fear. But if the victim did not learn of his hex through physical means, he could learn only by either telepathy or clairvoyance; and Carl had eliminated them.
The traditional list of paranormal powers included only two other phenomena; fire-sending and telekinesis.
Carl elected to consider the first as only a subdivision of the second. Speeding the Brownian Movement of molecules (i.e. heating them) to the point of flame was surely no different in kind than gross manipulation of groups of molecules (i.e. moving material objects).
His first attempt at telekinesis involved a weary time of attempting to shift bits of matter, papers first, then balanced pins, hanging threads, finally grains of dust on a micro-balance. There was no result. Co-opting some help from Classical Physics, Carl then began a series of tests involving photographic film. It was, the drafted physicists assured him, the medium in which the least physical force produced the greatest measurable effect. A photon, a free electron, almost any particle containing energy could shift the unstable molecules in the film emulsion.
Carl worked with higher and higher speed emulsions, learning tricks to make the film still more sensitive - special developers, close temperature control, pre-exposing the film to 'soak up' part of the energy necessary to produce an image. With each new batch of film he then sat for hours, attempting to paint circles, crosses and stars on the emulsion with his mind, visualizing the molecules and willing the change-over. He scissored out stencils and held them over the wrapped filmpacks, considering it possible that the psionic 'radiation' might show only as a point source. He had one temporary, and illusive, success: a plate of particularly trigger-happy film, wrapped under his pillow all one night, developed the next morning into a ghostly, wavering 'X.' Master Florian of Photo-chemistry disillusioned him. Carl had only succeeded in so sensitizing the film that it reacted to the tiny infra-red produced by his own body heat.
Master Carl's project for this night involved pre-exposing a specially manufactured batch of X-ray film, by means of contact with a sheet of luminescent paper; the faint gamma radiation from the paper needed hours to affect the emulsion, but those hours had to be accurately timed.
To fill the space of those hours, Master Carl had another pleasant task. He sent a student courier to his office for the unfinished draft he had abstracted from Cornut's room. It was headed:
A Reconciliation
Of Certain Apparent Anomalies
In Wolgren's Distributive Law
Carl drew a stiff-backed chair up to his desk and began to read, enjoying himself very much.
Wolgren's Law, which had to do with the distribution of non-uniform elements in random populations, was purely a mathematician's rule. It did not deal with material objects; it did not even deal with numerical quantities as such. Yet Wolgren's Law had found applications in every sort of sampling technique known to man, from setting parameters for rejecting inferior batches of canned sardines to predicting election results. It was a general law, but the specific rules that could be drawn from it had proved themselves in nearly every practical test.
In every test but one. One of Carl's graduate students had attempted to reconcile the Wolgren rule with census data for his doctoral thesis - queerly, the subject seemed never to have been covered. The boy had failed. He had found another subject, got his degree and was now happily designing communications systems for the TV syndicates, but in failing he had produced a problem worth the attention of a first-rate mathematician; and Carl had offered it to Cornut.
Cornut had worked on it, in his own after-hours time, for six months. Incomplete as it was, the report gave Master Carl three hours of intensive enjoyment. Trust Cornut to do a beautiful job! Carl followed every step, mumbling to himself; cocking an eyebrow at the use of chi-squared until it was proved by a daring extension of Gibb's phase-analysis rule. It was the mathematical statement that concerned him, not the subject of census figures themselves. It was only when he had finished the report and sat back, glowing, that he wondered why Cornut had thought it was not finished. But it was! Every equation checked! The constants were standard and correct, the variables were pinned down and identified with page after page of expansions.
'Very queer,' said Carl to himself, staring vacantly at the bench where his X-ray film was quietly soaking up electrons. 'I wonder—'
He shrugged, and attempted to dismiss the problem. It would not be dismissed. He thought for a moment of calling in Cornut, but stopped himself; the boy would not be back from his visit to Locille's family, and even if he were it was no longer feasible to burst in on him.
Dissatisfied, Master Carl read again the last page of the report. The math was correct; this time he allowed the sense of it to penetrate: 'Of n births, the attained age of the oldest member of the population shall equal n times a constant e-log q.' Well? Why not?
Carl was irritated. He glanced at his clock. It was only ten. Frowning, he buttoned his jacket and went out, leaving lights on, door open, report open on the desk ... and the X-ray film still firmly taped to its gamma-emitting paper.
No one answered his knock on Cornut's door, so Carl, after a moment's thought, pushed it open. The room was empty; they had not returned from the texas.
Carl grumbled at the night proctor and dropped in the elevator to the campus. He thought a stroll might help. It was chilly, but he scarcely noticed. The q quantity, was there something wrong with that? But its expansions were all in order. He recalled, as clearly as though they were imprinted on the wall of the Administrative Building ahead of him, the equations defining q; he even remembered what quantities those equations involved. Public health, warfare, food supply, a trickily derived value for the state of the public mind ... they had all been in the accompanying tabulations.
'Good night, Carl-san.'
He stopped, blinking through the woven iron fence. He had reached the small encampment where the aborigines were housed; the captain, whatever his name was, had greeted him. 'I thought you people were off - ah, lecturing,' he finished lamely. 'On exhibition,' he had been about to say.
'Tomorrow, Carl-san,' said the waffle-faced man, offering Carl a long, feathered pipe. That had been in the briefing; it was a peace pipe, a quaint and for some reason, to the anthropologist a surprising, custom of the islanders. Carl shook his head. The man - Carl remembered his name; it was Masatura-san - said apologetically, 'You softspeak hard, sir. I smell you comin
g long way yesterday.'
'Really,' said Carl, not hearing a word. He was thinking about e-log and the validity of applying it; but that was all right too.
'Softspeak brownie not smell good,' the man explained seriously.
'No, of course not.' Carl was wondering about the values for a, the age factor in the final equation.
Tai-i Masatura-san said, growing agitated, 'Cornut-san smell bad also, St Cyr-san speak. Carl-san! Not speak brownie!'
Master Carl glanced at him. 'Certainly,' he said. Good night.' After him the tai-i called beseechingly, but Carl still did not hear; he had realized what it was that was unfinished about Cornut's report. The numerical values had been given for every quantity but one. It was still early; he did not intend to sleep until he had that one remaining value...
Cornut, with his arm around Locille, yawned into the face of the red moon that hung over the horizon. It was growing very late.
They had to take the ferry to the city and wait to transfer; the only direct popper from the texas to the city was in mid-morning, and Locille's family had no place to put them up. Nor, if they had, would Cornut have stayed. He needed time to become accustomed to domesticity; it was too many things at once; bad enough that he should have to interrupt his routine to accommodate Locille's presence in his room.
But it was, on the whole, worth while.
The University was under them now, the cables of the Bridge lacing the red moon, the lights from the Administration Building bright in the dark mass of towers.
It was odd that the Administration Building should be lighted.
Drowsily Cornut looked, out of the corner of his eye, at the neat, sleepy head of his wife. He did not know if he liked her better or worse as a member of a family. The parents -dull. Amiable, he supposed, but he was used to brilliance.
And her brother was an unfortunate accident, of course, but he had been so enchanted with the rag Locille had brought him, like a child, like an animal. Cornut was not quite pleased to be related to him. Of course, you couldn't choose your relatives. His own children, for example, might be quite disappointing...
His own children! The thought had come quite naturally; but he had never had that particular thought before. Involuntarily he shivered, and looked again at Locille.
She said sleepily, 'What's the matter?' And then, 'Oh. Why, I wonder what they want.'
The ferry was coming in close, and on the hardstand several men were standing patiently, behind them a police popper, its blades still but its official-business light winking red. In the floodlights that revealed the landing X to the pilot, Cornut vaguely recognized one of the men, an administration staffer; the others all wore police uniforms.
'I wonder,' he said, glad that he didn't have to explain the shudder. 'Well, I'll sleep well tonight.' He took her hand and helped her, unnecessarily but pleasurably, down the steps.
A squat uniformed man stepped forward. 'Master Cornut? Sergeant Rhame. You won't remember me, but—'
Cornut said, 'But I do. Rhame. You were in one of my classes, six or seven years ago. Master Carl recommended you; in fact, he was your advocate at the orals for your thesis.'
There was a pause. 'Yes, that's right,' said Rhame. 'He wanted me to apply for the faculty, but I'd majored in Forensic Probabilistics and the Force had already accepted me, and— Well, that's a long time ago.'
Cornut nodded pleasantly. 'Good to see you again, Rhame. Good night.' But Rhame shook his head.
Cornut stopped, a quick, vague fear beginning to pulse in his mind. No one enjoys the sudden knowledge that the policeman in front of him wants to discuss official business; Rhame's expression told Cornut that that was so. He said sharply,'What is it?'
Rhame was not enjoying himself. 'I've been waiting for you. It's about Master Carl; you're his closest friend, you know. There are some questions—'
Cornut hardly noticed Locille's sudden, frightened clutching at his arm. He stated, 'Something's happened to Carl.'
Rhame spread his hands. 'I'm sorry. I thought you knew. The lieutenant sent word to have you called from the texas; probably you'd left before the message got there.' He was trying to be kind, Cornut saw. He said, 'It happened about an hour ago - around twelve o'clock. The President had gone to bed - St Cyr, I mean. Master Carl came storming into his residence - very angry, the housekeeper said.'
'Angry about what?' shouted Cornut.
'I was hoping you could tell us that. It must have been something pretty serious. He tried to kill St Cyr with an axe. Fortunately—' He hesitated, but could find no way to withdraw the word. 'As it happened, that is, the President's bodyguard was nearby. He couldn't stop Master Carl any other way; he shot him to death.'
CHAPTER XI
Cornut went through that night and the next day in a dream. It was all very simple, everything was made easy for him, but it was impossibly hard to take. Carl dead! The old man shot down - attempting to commit a murder! It was more than unbelievable, it was simply fantastic. He could not admit its possibility for a second. But he could not deny.
Locille was with him almost every moment, closer than a wife need be, even closer than a watchdog. He didn't notice she was there. He would have noticed if she were missing. It was as though she had always been there, all his life, because his life was now something radically new, different, something that had begun at one o'clock in a morning, stepping out of a ferry popper to see Sergeant Rhame.
Rhame had asked him all the necessary questions in a quarter of an hour, but he had not left him then. It was charity, not duty, that kept him. A policeman, even a forensic probabilistician detailed to Homicide at his own personal request, is used to violence and unlikely murderers, and can sometimes help to explain difficult facts to the innocent bystanders. He tried. Cornut was not grateful. He was only dazed.
He cancelled his classes for the next day - tapes would do - and accompanied Rhame on a laborious retracing of Carl's last moves. First they visited St Cyr's residence and found the President awake and icy. He did not seem shaken by his experience; but then, he never did. He gave them only a moment of his time. 'Carl a kill-er. It is a great shock, Cor-nut. Ge-ni-us, we can not ex-pect it to be sta-ble, I sup-pose.' Cornut did not want to linger. St Cyr's presence was never attractive, but the thing that repelled him about the interview was the sight of the fifteenth-century halberd replaced on the floor where, they said, Master Carl had dropped it as the gunman shot him down. The pile of the carpet there was crisper, cleaner than the rest. Cornut was sickly aware that it had been cleaned, and aware what stain had been so quickly dissolved away.
He was glad to be out of the President's richly furnished residence, though the rest of the day was also no joy. Their first stop was the night proctor on Carl's floor, who confirmed that the house master had left at about ten o'clock, seeming disturbed about something but, in his natural custom, giving no clue as to its nature to an undergraduate. As it did not occur to them to question the aborigines, they did not learn of his brief and entirely one-sided conversation, but they picked up his trail at the next point.
Master Carl had turned up at the stacks at twenty-five minutes past ten, demanding instant service from the night librarian.
The librarian was a student, working off part of his tuition, as most students did. He was embarrassed, and Cornut quickly deduced why. 'You were asleep, weren't you?'
The student nodded, hanging his head. He was very nearly asleep talking to them; the news of Master Carl's death had reached every night clerk on the campus, and the boy had been unable to get to sleep. 'He gave me five demerits, and—' He stopped, suddenly angry with himself.
Cornut deduced the reason. 'Consider them cancelled,' he said kindly. 'You're quite right in telling us about them. Sergeant Rhame needs all the information.'
'Thank you, Master Cornut. I - uh - I also didn't have a chance to get the ashtray off my desk, and he noticed it. But he just said he wanted to use the stacks.' The undergraduate waved towards the great air-condit
ioned hall where the taped and microfilmed University Library was kept. The library computer was served by some of the same circuits as the Student Test-Indices (College Examinations) Digital Computer on the level above it; all the larger computers on the campus were cross-hooked to some degree.
Rhame was staring at the layout. 'It's got more complicated since I was here,' he said. 'Did Master Carl know how to use it?'
The student grinned. 'He thought he did. Then he came storming back to me. He couldn't get the data he wanted. So I tried to help him - but it was classified data. Census figures.'
'Oh,' said Cornut.
Sergeant Rhame turned and looked at him. 'Well?'
Cornut said, 'I think I know what he was after, that's all. It was the Wolgren.'
Rhame understood what he was talking about - fortunately, as it had not occurred to Cornut that anyone would fail to be aware of Wolgren's Distributive Law. Rhame said, 'I only use some special Wolgren functions; I don't see exactly what it has to do with census figures.'
Cornut sat down, beginning to lecture. Without looking he put out his hand and Locille, still with him, took it. 'It's not important to what you're looking for. Anyway, I don't think it is. We had a question up for study - some anomalies in the Wolgren distribution of the census figures - and, naturally, there shouldn't be any anomalies. So I took it as a part-time project.' He frowned. 'I thought I had it beaten, but I ran into trouble. Some of the values derived from my equations turned out to be ... ridiculous. I tried to get the real values, but I got the same answer as Master Carl, they were classified. Silly, of course.'
The student librarian chimed in, 'He said moronic. He said he was going to take it up with the Saint—' He stopped, blushing.
Rhame said, 'Well, I guess he did. What were the values that bothered you?'
Cornut shook his head. 'Not important; they're wrong. Only I couldn't find my mistake. So I kept going over the math. I suppose Carl went through the same thing, and then decided to take a look at the real values in the hope that they'd give some clue, just as I did.'
