  “That situation ended twenty days ago. On that date, an anomalous energy demand triggered a flag in our general power monitoring system.

  “This concludes the first part of my testimony.” Brachis glanced from one Ambassador to the next. “Are there questions?”

  The four figures facing him were silent. There was only the usual faint hiss of the Mattin Link connection. The Angel was restlessly waving its upper lobes, while Dougal MacDougal was glancing from side to side. Brachis knew better than to expect support from the Solar Ambassador.

  “With your permission, then, I will continue. The changed energy requirement that I referred to came directly from Cobweb Station. Unfortunately it happened during a quiet period, very near to a change of shift. The evidence of increased load was not at first noticed by my staff. I take full responsibility for that operational failure. However, the demand change was registered by our automatic monitoring system, together with a lengthy communications silence. A probe was dispatched to Cobweb Station.

  “It arrived too late. All my staff were dead. The station was empty of human life. The Mattin Link had been operated. And I finally learned things about the nature of Operation Morgan that I should have taken the time to learn long ago. All activities at Cobweb Station are under my jurisdiction. I take full responsibility for what happened there.”

  He had finished his testimony and was ready to stand down, but now there was a stir from the ranks of the Ambassadors. “You said that the Mattin Link was activated.” It was the Pipe-Rilla, gently vibrating her thorax plates. “For transmission of objects, or for signals only?”

  “For objects.”

  “Then, to what destinations?”

  “I do not know. But the energy drain says that it must have been many lightyears.”

  As Brachis was giving his testimony, new individual components had flown in silently to join the Tinker Composite. Now it bulked much larger than a human. There was a fluttering of tiny purple-black wings, and then a sibilant facsimile of human speech came again through the Link. “We would like the records, if you please. We wish to attempt our own analysis of possible destinations. And we wish to know more about the nature of the project you term Operation Morgan.”

  “Very well. But for that, I will with your permission defer to Commander Mondrian. My own records will be sent to you at once, and I will of course be available to answer any further questions.” Luther Brachis stepped back, ceding the spotlight to Esro Mondrian.

  His companion had been performing his own close inspection of the Ambassadors. There was no chance of recognizing any particular assembly of Tinker Composites, but the Angels and Pipe-Rillas both had stability of structure. It was possible that he had met one of them before, on their own home worlds. In any case, he knew he would have to talk right past Dougal MacDougal if he hoped for any kind of sympathetic response from the alien Ambassadors.

  “My name is Esro Mondrian. I am Chief of Boundary Survey security. My territory begins half a lightyear from Sol, where it meets the region controlled by Commander Brachis. It extends all the way out to, and includes, the Perimeter. Between us, Commander Brachis and I divide the responsibility for human species security. However, Operation Morgan was my initiative and its failure is my responsibility, not his.

  “I have worked in the past with each of your own local monitoring groups, and I have visited your home systems. We are fortunate, all our species, in that we live in stable, civilized regions, where there are few unknown dangers. But out on the Perimeter, fifty lightyears and more from Sol, there are no such guarantees.”

  Down in the sunken atrium in front of Mondrian there was an odd grunting sound. It was Dougal MacDougal, clearing his throat. He did not speak, but he did not need to. Mondrian understood the message. Get on with it, man. The Ambassadors didn’t link in from halfway to the Perimeter just to hear platitudes from you.

  And yet they had to hear this, whether MacDougal liked it or not. Esro Mondrian hurried on.

  “Out on the Perimeter, distances are enormous. But our resources to monitor what is happening out there are limited, and operating uncertainties are large. A few years ago I realized that we were losing ground. The Perimeter constantly increases in size, but our capability was not growing with it. We had to have some new type of monitoring instrument—one that could function with minimal support from the home bases, and also one that was tougher and more flexible than anything that we could make with the pan inorganica brains. It was while I was wrestling with that problem, and evaluating alternatives—none of them satisfactory—that I was approached by a scientist, Livia Morgan. She offered an intriguing prospect. She could, she claimed, develop symbiotic forms that combined organic and inorganic components. By the end of our first meeting, I was convinced that what she had might be perfect for our needs.” Mondrian nodded at one of the figures in front of him. “I also knew of at least one example, sufficient to prove that such a blend of organic with inorganic was not impossible.”

  The Angel acknowledged the reference with a wave of blue-green fronds. It was itself a symbiotic life-form, discovered a century and a half earlier when the expanding wave-front of the Perimeter had reached the star Capella and the planets around it. The visible part of the Angel was the Chassel-Rose, slow-moving, mindless, and wholly vegetable. Shielded within the bulbous central section lived the sentient crystalline Singer, relying upon the Chassel-Rose for habitat, transportation, and communication with the external world.

  “Imitation is the sincerest form of flattery,” said the computerized voice of the Angel.

  Mondrian stared back at the gently waving fronds. The Angels had that disconcerting habit of employing human cliches and proverbs at every opportunity. No one was ever sure if it represented the symbiote’s perverse ideas of racial politeness, or served some wild sense of humor.

  “Regarding the entities that Livia Morgan proposed to create.” Mondrian had realized after a few seconds that the Angel intended to offer no further comment. “I will from this point term them the Morgan Constructs. They were designed specifically to patrol the Perimeter. Their performance specifications were drawn very precisely. Each unit had to be mobile, durable, and highly intelligent. Livia Morgan told me once that they would be—I quote—’indestructible.’ Fortunately, she was exaggerating. However, they were designed to be very tough, since they would cruise the unexplored regions of the Perimeter, and perhaps there encounter life forms inimical to them and to everyone in the Stellar Group. However, I intended that they should serve a reporting function only. They would be able to protect themselves from attack, but they would not, under any circumstances, harm a known intelligent life form, or any life form that might possibly have intelligence.

  “I was present at every initial demonstration of the Morgan Constructs. They were exposed to each of our four species, and to the seven other possibly intelligent organisms within the Perimeter. They were also allowed to interact with a variety of Artefacts, simulacra of differing degrees of apparent intelligence. The Constructs recognized each known form. The unknown ones, they responded to in a friendly and harmless manner. They treated the Artefacts with caution and respect. When attacked themselves, they did no more than remove themselves from harm’s way. However, they did so too reluctantly, and would have been destroyed in any real attack. I therefore authorized the next stage of the work, to raise the Constructs to a higher level of sophistication. Livia Morgan began that program. But somehow, out on Cobweb Station, a crucial design blunder must have been made.” Mondrian faced Dougal MacDougal. “May I show the images obtained by the probe?”

  “Carry on. But hurry. We can’t hold the Link indefinitely.”

  “I want to warn you all, these scenes are deeply disturbing.” As Mondrian spoke, a sphere of darkness was forming behind him. Within it glowed the rough-textured ovoid of Cobweb Station as it had been seen by one of the bristle probes. At first the whole station sat in the field of view. It grew in size, and increased st
eadily in resolution. Soon dozens of flattened and twisted objects could be seen, floating outside the airlocks. Many of them were quite unrecognizable, little more than fused fragments of metal and plastic. The camera ignored those. It closed remorselessly on a score of space suits. Each one was filled, but if their occupants had been alive when they were expelled from the locks, they would not have survived for long. The detailed images showed missing limbs, disemboweled trunks, and headless torsoes. The camera locked on one figure, a turning eyeless corpse that lacked feet and hands.

  “That is the mortal remains of Dr. Livia Morgan.” Mondrian’s voice was unnaturally calm. “Although neither she nor the guards were able to send distress signals from Cobweb Station, the monitors preserved a complete record of their last few hours. Based on that evidence, Morgan Constructs are cunning, and deadly, and utterly inimical to human life. I would like to express my admiration for the performance of the guards assigned to Cobweb Station by Commander Brachis. Although they had no warning when the Constructs ran wild, they did not give up or panic. There were seventeen Morgan Constructs on Cobweb Station, each at a different stage of development, and each designed with a different level of sophistication. The guards were able to destroy fourteen of them completely, inside or outside the station, but with great loss of life. Dr. Morgan and four surviving guards attempted to negotiate with the remaining three. She was seized and systematically dismembered. Unless you insist, I do not propose to show you details of those scenes.

  “The remaining guards were hounded through the station interior. They managed to destroy two more Morgan Constructs before they were killed themselves. By the time that the bristle probes reached Cobweb Station, it was empty of all life.

  “Seventeen Constructs.” The whistling voice of the Tinker Composite spoke at once. “Fourteen died, and later two more . . .”

  “You are quite correct.” The images behind Mondrian were fading. “As Commander Brachis told you, the Mattin Link had been operated. That should have been impossible for a Construct which had received no assistance or training. It is a further proof of extraordinary intelligence. The seventeenth Morgan Construct—the most recently developed, and the most sophisticated—has disappeared. We are doing our best to trace it, but our working assumption must be a pessimistic one. Somewhere within the fifty-eight lightyear radius of the Known Sphere—close to the Perimeter, we hope, rather than near one of our home worlds—there is a formidable threat, of unknown magnitude. I do not believe that any of our races is in immediate danger, particularly since the Constructs were designed and trained to work out on the Perimeter, and it is likely that the escaped one will have chosen to flee there. But we cannot guarantee that, or that the Construct will stay in one place. The purpose of today’s meeting was to inform you of these unfortunate facts; and to hear your suggestions as to ways of dealing with the situation. That is the end of my official statement. Are there questions?”

  Mondrian waited, glancing from one oval pool of light to the next. The Tinker, Angel, and Pipe-Rilla were too alien for him to be able to read their feelings. Dougal MacDougal merely seemed irritable and decidedly uneasy.

  “Then, your Excellencies.” Mondrian took a step backwards, intending to align himself with Luther Brachis. “With your permission—”

  “Questions!” The fourteen-foot figure of the Pipe-Rilla was unfolding, rising high on its stick-thin legs. The forelimbs were clutching the tubular trunk, and the long antennas were waving. “I have questions.”

  Mondrian stepped forward again and waited, while the Pipe-Rilla went through a writhing of limbs and a preliminary buzzing.

  “Tell us more about the capability of the Morgan Constructs. A being, designed for defense but turned against its makers, sounds unpleasant. But it does not sound like a great threat, or a cosmic issue. Presumably you designed these Constructs without major means of aggression?”

  “They were designed that way, true enough.” Mondrian glanced around, to see if Luther Brachis wanted to make any comment. The other man seemed more than ready to stay in the background. “However, as I mentioned, the Constructs were all equipped with considerable powers of self-defense, to protect them from possible enemies of unknown strength. Remember, they were supposed to operate alone, far from any support, against any dangers. Unfortunately, their defensive powers can also be used offensively. Their power plants can produce small fusion weapons. Their power lasers and shearing cones are enough to destroy any ship. They contained the best detection equipment that we could produce, since we wanted them to be able to find other life forms at the longest possible range. I could give you full details, but perhaps a single example is more informative: any single Morgan Construct could destroy a city, or lay waste a fair-sized planetoid. The surviving Construct, unfortunately, was the best equipped of the seventeen that were made.”

  Throughout Mondrian’s reply there had been a slow stirring within the Tinker Composite. As he ended there came a burst of speech, so fast that the computers cut in to decipher and re-translate it.

  “Why?” gabbled the Tinker. “Why, why, why? In the name of Security, you humans have produced a danger to yourselves and to all the other species of the Stellar Group. Why does anyone need a Morgan Construct? Consider yourselves. You have been exploring the region around vour Sun for six hundred of your years. We have watched that exploration for more than three centuries, ever since humans discovered our world and offered us space travel. And what have we seen? The Perimeter now encloses a region one hundred and sixteen lightyears in diameter, with more than two thousand star systems and a hundred and forty-three life-supporting planets. And nowhere, at any place within that vast region, has any species been found that is in any way murderous or aggressive—except your own. You humans are lifting a mirror to the universe, seeing your own faces within it, and declaring the cosmos terrifying. We, the Tinkers, say two things: first, until you created your Morgan Constructs there was no danger anywhere. Second, tell us why you continue this insane rush to expand the Perimeter. It now ends fifty-eight lightyears away from Sol. Will you humans be satisfied when it has reached eighty lightyears? Or one hundred lightyears? Will you stop then? When will you stop?”

  Esro Mondrian looked to MacDougal. He saw no support there. “I cannot answer your general questions, Ambassador. However, I can make a relevant point. I have long suggested that the Perimeter be frozen, or at least the expansion slowed. You say that the region within the Perimeter has no dangers to any of us—”

  “Had none.” The Tinker was a blizzard of components, flying furiously about the central cluster. “Had none until your species created one.”

  “—but the region outside the Perimeter may contain absolutely anything. Who knows how dangerous it might be, to all of us?” Mondrian turned to face the Terran area of the atrium. “With all respect, Ambassador MacDougal, I must say that I agree completely with the Tinker Ambassador. I know that such decisions are made at levels well above mine, but as long as expansion does proceed, something like the Morgan Constructs is essential. We must take measures to protect ourselves against whatever lies—”

  “That’s enough.” Dougal MacDougal moved one hand, and the lights illuminating Esro Mondrian were instantly extinguished. “Commander, you are removed from the witness stand. You were brought here to present a statement of a situation, not to offer your personal—and unsound—views on human exploration.” MacDougal moved out of the atrium, and turned so that he could be seen by the other three ambassadors of the Stellar Group. “Fellow Ambassadors, my apologies to all of you. As you have heard, both these men bear fault in permitting this serious problem to arise. Their own words convict them of error and of negligence. As soon as this meeting is over, you have my word that I will move at once to have them removed from office. They will never again be in a position to—”

  “No-o-o.” The word came rolling from the Angel, delivered slowly and heavily through its computer link. “We will not permit such action.”


  Rarely for nim, MacDougal was caught off balance. “You mean—you do not want me to dismiss Commander Mondrian and Commander Brachis?”

  “No indeed.” The topmost frond of the Angel went into slow but wide-ranging oscillation. “That cannot be. The punishment must fit the crime. We, the Angels of Sellora, request a move at once to Closed Hearing. We request full closure, without staff. There should be no one but Ambassadors present.”

  “But then the record—”

  “There must be no record. The subject for discussion is a question so serious that it can be pursued only in full closed hearing. For this, we invoke our ultimate Ambassadorial privilege.”

  Even as the Angel spoke, an opaque screen was flickering into existence around the atrium. The lighted areas around the four Ambassadors were visible for a few seconds more, then there was nothing in the center of the Star Chamber but a ball of scintillating darkness.

  Luther Brachis stepped forward to stand next to Esro Mondrian. The two men were alone, outside the dark sphere. Within it sat the four Ambassadors of the Stellar Group. Their earlier meeting had been the first full audio and visual meeting in twenty-two years. Now came the first Closed Hearing in more than a century.

  Chapter 2

  Mondrian and Brachis had clearly been excluded from the Ambassadorial meeting. Just as clearly, they had not been given permission to leave the Star Chamber. There was nowhere to go, nothing to do.

  That should have been no problem. With overlapping areas of jurisdiction, the two men had a thousand points of shared responsibility and a hundred disputes to settle.
