  "Louis Nenda is basically human," Graves went on, "but with some Zardalu augmentation."

  "Mental or physical?"

  "I do not know. But whatever was done, it must be fairly minor. There's no mention of rear-skull or fingertip eyes, no hermaphroditism, no deboning or quadrimanuals or quadripedals. No gigantism or compaction—he's male, and standard size and weight according to the manifest. Of course, there are hundreds of modifications that don't appear on any standard list.

  "As for the pet that he brings with him, I can tell you even less. It is a Hymenopt, and needless to say, it is another arthropod—though similar to Earth's Hymenoptera only by analogy. But whether it is a plaything, or a sexual partner, or even a food supply for Nenda—that we will have to wait and see."

  And not wait long, Rebka thought. The newly arrived ship sat in the middle of Starside Port, its occupants already in screening for organisms at the arrival building. Since tests for endo- and ecto-parasites took only a few minutes, the newcomers had to be in the final stages of entry.

  Rebka and Graves moved to where Max Perry and three officials from Port Entry were already waiting.

  "How much longer?" Rebka asked.

  Instead of replying, Perry gestured to the sealed double doors of Decontamination. They were beginning to open.

  After Graves's suggestions and Rebka's imaginings, Louis Nenda looked surprisingly normal. Short, swarthy, and muscular, he could have passed for an inhabitant of one of the denser worlds of the Phemus Circle. He was a little unsteady on his feet, probably the result of half a dozen changes of gravity in the past few hours, but he had plenty of pep, and his self-confidence showed in his walk. He glared arrogantly around with bloodshot eyes as he strutted out of the exobiology test unit; trotting by his side, mimicking his head movements, came a chubby little alien. It halted when it saw the group of waiting humans.

  "Kallik!" Louis Nenda tugged on the harness that passed around the Hymenopt's thorax and encased the abdomen. "Heel."

  Then, without a look at anyone except Perry, he said, "Good morning Commander. I think you'll find I test negative. Kallik also. Here's my access request."

  The other men were still staring at the Hymenopt. Julius Graves had seen one in travels through the Zardalu territories, but the rest of them knew only pictures and stuffed specimens.

  The alien was hard to match to the Hymenopt's fierce reputation. It was less than half the height of Louis Nenda, with a small, smooth head dominated by powerful traplike mandibles and by multiple pairs of bright black eyes set in a ring around the perimeter. They were in constant motion, independently tracking different objects around it.

  The Hymenopt's body was rotund and barrel-shaped and covered with short black fur, a centimeter or two long. That was the prized Hymantel, a tough, water-resistant, and insulating coat.

  What was not visible was the gleaming yellow sting, retracted into the end of the blunt abdomen. The hollow needle delivered squirts of neurotoxins, whose strength and composition the Hymenopt could vary at will. No standard serum could be effective as an antidote. Also invisible was the nervous system that provided a Hymenopt with a reaction speed ten times as fast as any human's. Eight wiry legs could carry it a hundred meters in a couple of seconds, or fifteen meters into the air under standard gravity. The Hymantel had been a seldom-seen item of human clothing, even before the Hymenopts had been declared a protected species.

  "Welcome to the Dobelle system." Perry's voice said the opposite of his words. He took the access requests from Louis Nenda and glanced through them. "Your original request said little about the reason why you wish to visit Quake. Do you have more details here?"

  "Sure do." Nenda's manner was as cocky as his walk. "I want to look at big land tides, and that means Quake. At Summertide. No problem in that, is there?"

  "Quake is dangerous at Summertide. More dangerous than ever, with Amaranth coming so close."

  "Hell, I don't care about danger." Nenda stuck out his chest. "Me and Kallik, we eat danger. We were down on Jellyroll when they had the hyperflare. Spent nine days in an aircar, chasing round in Jellyroll's shadow to avoid being roasted, got out without even a tan. Before that we were on the next-to-last ship out of Castlemaine." He laughed. "Lucky for us. Last ship out had no supplies and a forty-day crawl to a Bose Node. They had to eat each other. But for a real experience let me tell you what happened on Mousehole—"

  "As soon as we've had a chance to review your request." Perry gave Nenda an angry glance. Even on one minute's exposure it was clear that the newcomer would not take it well if his application were rejected. "We'll show you to temporary accommodation, then some of us need to have a meeting. Is there anything special that he"—he gestured at the Hymenopt—"needs to eat?"

  "She. Kallik is female. No, she's an omnivore. Like me." Nenda laughed with no trace of humor. "Hey, I hope I'm not hearing what I think I'm hearing. What's all this 'need to have a meeting' stuff? I've come a damned long way for this. Too far to get the runaround now."

  "We'll see what we can do." Perry glanced down at Kallik. At the fury in Louis Nenda's voice a couple of inches of yellow sting had slid from its sheath. "I'm sure we agree on one thing: You don't want to go to Quake and be killed there."

  "Don't you worry your head about us. We don't kill easy. Just approve that access request and let me get over there. It'll take more than Quake to do me in."

  Maybe it would. Rebka watched as Perry led the newcomer away. Quake was dangerous, no doubt about it; but if self-confidence were any protection, Louis Nenda would be safe anywhere. Maybe it was Quake that needed the protection.

  "I would like to hear your recommendation, Commander."

  But Perry won't look at me, Rebka thought. He thinks he knows my decision. But he's wrong—because I don't know it myself.

  "I oppose Summertide access, as you know." Perry's voice was barely audible, and his face was pale.

  "Oppose access for anyone?"

  "That's right."

  "You know that Graves will simply overrule whatever we decide? He has the authority to hunt for the Carmel twins on Quake, anytime he wants to."

  "He has that authority, and we both assume that he will go. But authority won't protect him. Quake at Summertide is a killer." Perry's voice rose on the final word.

  "Very well. What about the others? They are willing to pay Dobelle very substantial amounts for the privilege of visiting Quake."

  "I would approve their visits—well after Summertide. Darya Lang can study the Umbilical without being on the surface; Atvar H'sial has the whole rest of the year to study species under environmental stress."

  "They'll never agree. Refuse access at Summertide, and you lose them and the money they would pay to Dobelle. What about Louis Nenda?"

  Perry finally met Rebka's eye, and a different tone came into his voice. He even managed a smile. "He's lying, isn't he?"

  "I certainly think so."

  "And he's not very good at it."

  "He doesn't give a damn. He should have picked a more plausible story. He strikes me as the last man in the spiral arm to be interested in land tides—I'm tempted to get Steven Graves to ask him a few technical questions about them. But that wouldn't solve anything. He came a long way to get here, nearly nine hundred light-years—unless he's lying about everything else, as well. But he certainly came from the Zardalu Communion, and that's at least four Bose Nodes. Any suggestions as to what he's really after?"

  "I have no idea." Perry went quiet again and looked far off at something invisible. "But I don't think he's the only one who's lying. The inquiry you sent to Circle intelligence about Darya Lang confirmed that she's an expert on Builder artifacts, but there's no reason for her to go down to the surface of Quake. She could do all her work here, or on the Umbilical itself. But whether she's telling the truth or not doesn't make any difference to my opinion. You asked for a recommendation. I'm giving it: no access for Lang, no access for Atvar H'sial, no access for anyone until
after Summertide. And if Graves chooses to override us, that's up to him."

  "You would let him go to Quake alone?"

  "God, no." Perry was genuinely shocked. "You might as well kill him here. I'd go with him."

  "I thought so." Rebka had made up his mind. "And so will I."

  And for all the wrong reasons, he thought. If I allow access to Quake, I may find out why everyone is so keen to go there. But if I refuse access, I'll find out just how keen they are. And I'll probably force some of them to take action. That, I know how to deal with.

  "Commander Perry," he continued. "I have made my decision. I agree with your recommendation." He smiled inwardly at the surprise on Perry's face. "We will refuse access to Quake for all parties until Summertide is over."

  "I feel sure that's the right decision." Perry's self-control was excellent, but the expression of relief could not be hidden.

  "Which leaves us one more decision to make," Rebka said. "Maybe we should toss a coin for it. Who is going to give the bad news to Darya Lang and to Atvar H'sial? Worst of all, who will tell Louis Nenda?"

  ARTIFACT: LENS.

  UAC#: 1023

  Galactic Coordinates: 29,334.229/18,339.895 / — 831.22

  Name: Lens Star/planet association: None, free space entity

  Bose Access Node: 108 Estimated age: 9.138 ± 0.56 Megayears

  Exploration History: The full history of Lens may never be known. Lying as it does in the clade of the Zardalu Communion, all early records were lost with the collapse of the Zardalu Empire. However, given the preoccupation of the Zardalu with biological science and their relative indifference to physical ones, it is most unlikely that any systematic exploration of Lens was ever attempted by them.

  The recorded history of Lens begins with its observation in E.122, but it was long assumed to be extragalactic. The local nature, as part of the spiral arm, was discovered in E. 388 from parallax effects. The Lens was approached directly in E. 2102 by Kusra (one-way journey), but no physical evidence for material existence could be obrtained. Paperl and Ula H'sagta (E. 2377) measured a polarization change of beamed lasers passed through the region of the Lens, confirmed its location, and mapped its extent.

  Physical Description: The Lens is a focusing region of space, 0.23 light-years in diameter and of apparently zero thickness (grazing incidence measurements have been made down to one micrometer). Focusing is performed only for light with wavelength range of 0.110 to 2.355 micrometers, approaching within 0.077 radians of normal incidence to the plane surface of the Lens. There is, however, weak evidence of interaction with radiation of wavelength in excess of 0.1 Iight-years (the low energy of such radiation makes its separation from cosmic background of debatable validity). All other light, all particles or solid objects, and all gravity waves pass through the Lens apparently unaffected. Radiation focusing appears to be perfectly achromatic for all wavelengths in the stated range. In that range, the Lens performs as a diffraction-limited focusing device of 0.22 light-years effective aperture and 427 light-years focal length. With its aid, planetary details have been observed in galaxies more than one hundred million parsecs distant.

  Physical Nature: This must unfortunately comprise an eliminative list of what the Lens is not. Today's science and technology can provide no tenable suggestion as to what it is.

  The Lens is not built on any particles known to today's inhabitants of the spiral arm. It is not a form of space-time singularity, since such a singularity cannot affect light of certain wavelengths and leave all other forms of matter and radiation untouched. For the same reason, it cannot be an assembly of bound gravitons. It cannot possess a superstring or superloop structure, since no spontaneous or induced emission is observed.

  Intended Purpose: Unknown. The Lens represents macroengineering by the Builders at its largest and most mysterious. The specific wavelength range has, however, induced some students of the artifact to speculate that this range corresponds to the spectral sensitivity range of Builder eyes. Since there is no evidence that the Builders possessed anything equivalent to eyes in human or Hymenopt terms, the conjecture is of passing interest only.

  It has also been conjectured that the Lens performs modulation of the light passing through it, in a way not understood. If so, its function as a focusing lens would be no more than an accidental by-product of the structure's true purpose.

  CHAPTER 10

  Summertide

  minus eighteen.

  "Come in," Darya Lang called out automatically when she heard a tentative knock on the door. She saw it swing open.

  "Come in," she repeated. Then she saw that the visitor was already in, or partially so. Just a foot above the ground, a round black head with a ring of bright eyes was peering past the edge of the open door.

  "She don't understand you worth a damn," a gruff voice said. "Only knows a few command words in human talk. Get in there."

  A frowning, squat, and swarthy man came striding through the door, pushing a diminutive alien ahead of him. A stiff halter around the Hymenopt's plump thorax was connected to a black whipping cane in the man's hand.

  "I'm Louis Nenda. This here"—a downward jerk of the cane—"is Kallik. Belongs to me."

  "Hello. I'm Darya Lang."

  "I know. We need to talk."

  He was the worst yet. Darya was becoming impatient with the level of manners in the Phemus Circle. But it was catching. "You may need to talk. I certainly don't. So why don't you leave now?"

  Unexpectedly, he grinned. "Wait and see. Where can we talk?"

  "Right here. But I don't see why we should."

  He shook his head and jerked his thumb toward J'merlia. The Lo'tfian had recovered enough to be released from the support harness, but he still preferred to remain where he could raise himself aloft for sleep periods. "What about the stick insect?"

  "He's all right." She bent to look at the ocular membrane. "He's just resting. He'll be no trouble."

  "I don't care what he's doing. What I have to say can't be said in front of that bug."

  "Then I don't think I want to hear it, either. J'merlia isn't a bug. He's a Lo'tfian, and he's as rational as you are."

  "Which don't impress me too much." Nenda grinned again. "There's people say I'm crazy as a Varnian. Come on, let's go talk."

  "Can you give me one reason why I should want to?"

  "Sure. I can give you twelve hundred and thirty-seven of 'em."

  Darya stared at him. "Are you talking about the Builder artifacts? Only twelve hundred and thirty-six of those have been discovered."

  "I said reasons. And I bet we can both think of one very good reason for talking that's not an artifact."

  "I don't know what you mean." But Darya could feel her traitorous face, as usual, betraying her.

  "Kallik, stay." Louis Nenda added a set of whistles and grunts to the words. He turned to Darya. "Speak any Hymenopt? Thought not. I told her to go over there and keep an eye on the bug. Come on outside. She'll come get us if it wakes up and needs you."

  He loosed the cane from Kallik's halter and headed out of the door and out of the building, not even looking back to see if she was following.

  What did he know? What could he know? Logic said, not a thing. But Darya found herself following him out onto the sodden surface of the Sling.

  Starside Weather Central was predicting another major storm in a day, but for the moment the winds had died away to warm and humid gusts. Mandel and Amaranth were together in the sky, fuzzy bright patches on the cloud layer. Amaranth was growing rapidly in apparent brightness. Green plants had become edged with copper, and there was a rusty tinge to the eastward sky. Louis Nenda walked confidently into the brush—no worries for him about giant tortoises, Darya thought. But by now they should all be safely out at sea, anyway, ready to ride out Summertide.

  "That's far enough," she called after him. "Tell me what you want."

  He turned
around and came back toward her. "All right, this'll do. I just don't want an extra audience, that's all. And I assume you don't."

  "I don't mind. I have nothing to hide."

  "Yeah?" He was smiling up at her, half a head shorter. "Funny, I'd have thought you might. You're Darya Lang, the Fourth Alliance's expert on Builder technology and Builder history."

  "I'm not an expert, but I am very interested in the Builders. That's no secret."

  "It's not. And you're famous enough so that the Builder specialists in the Zardalu Communion know all about your work and the Lang Catalog. You get invited to conferences and meetings, don't you, all the time? But you've never traveled, they all say, not for a dozen years. Anyone who wants to see Darya Lang, they make that trek to Sentinel Gate. Except that a couple of months ago, you can't be reached there. All of a sudden you take off. For Dobelle."

  "I want to explore the Umbilical."

  "Sure. Except according to the Lang Catalog, UAC 279—"

  "UAC 269," said Darya automatically.

  "Sorry, UAC 269. Anyway, it says—mind if I quote you?—the Umbilical is 'one of the simplest and most comprehensible of all Builder artifacts, and is for that reason of less interest to most serious students of Builder technology.' Remember writing that?"

  "Of course I do. What of it? I'm a free agent; I can change my mind. And I can go where I like.

  "You can. Except that your bosses back on Miranda made a big mistake. They should have told people who asked that you'd gone off to Tantalus, or Cocoon, or Flambeau, or one of the other really big Builder draws. Or maybe just say you'd gone off for a holiday."

  "What did they say?" She should not have been asking, but she had to know. What had those dummies back in central government done to her?"
