Agent of Vega and Other Stories

by James H. Schmitz

  Dowland was coming back from the grid-car with his mountaineering harness and portable communicator when the hogs began to scream again. He stopped, startled. There was an odd and disturbing quality to the racket this time—even more piercing than before—and, unless he was mistaken, the huge animals were in a sudden panic about something. Next, he heard them slamming against the sides of the corral, apparently trying to break out of it. His heart started to pound with instinctive alarms. Should he go down and investigate? Then, before he could decide, he heard through the din of the hogs, swelling gradually to almost match those incredible shrieks in volume, another sound. For a moment, something seemed to shut off Dowland's listening to the rumble and roar of a rushing, turbulent mass of water—and his ears told him it was passing by beneath him.

  * * *

  It might have been almost two minutes later before Dowland began to think clearly again. He had reached the house at a dead run—a senseless flight reaction under the circumstances, not far from complete panic. In the darkness outside, the mesa had seemed to sway and tilt, treacherous footing over the eerie booming of a river which had rolled through a long-dead past. In those seconds Dowland hadn't thought to question Jill Trelawney's story about a machine that brought about shifts in time. His senses seemed to have as much evidence to support it as anyone could demand.

  Back in the house, though the thundering disturbance continued, that conviction rapidly faded. He could close his eyes and immediately have the feeling of being on an unstable bridge above the swirls of some giant current. He could open them again and tell himself that YM-400 had a reputation for freakish effects—and that this specific effect, at any rate, should not be very harmful since Jill had reported it as having occurred on three separate occasions during the preceding day. To speak of such a commotion as being only the sound of a "river flowing under the house" seemed to approach the outrageous in understatement; but Jill Trelawney had turned out to be an unusual young person all around.

  She and her uncle hadn't stirred, but Dowland knew that their presence in the room steadied him. He knew, too, that, whatever happened next, he couldn't allow himself to be rattled into blind fright again. The situation was dangerous enough. If he let his nerves stampede him, he would find himself unable to take any effective action.

  He went over deliberately to the mountaineering harness he had dropped when he entered the lighted room, and began to check through the equipment. He intended to carry, in addition, only the communicator, the IPA gun, a canteen of water, and a small flashlight; and he would abandon the harness and its items at the foot of the mesa. There were two hunting rifles in the car, with a vastly better range than the handgun; but a rifle would slow him down and would make very little real difference if he had the bad luck to run into Carter's Troopers in the desert.

  Somewhat to his surprise, the underground tumult appeared to be growing fainter before he had concluded his inspection. Dowland paused to listen, and within a few seconds there was no more doubt about it. Jill had said it had gone on for half an hour on each of the previous occasions; but Dowland's watch confirmed that the present disturbance was subsiding rapidly after less than ten minutes. By the time he stood up, snapped on the harness and shrugged it into position, it had become almost inaudible.

  Which might be a good sign, or a bad one, or without particular significance of any kind. He couldn't know, and he'd probably be better off if he didn't start thinking too much about it. He turned for a last survey of the room before setting out, and discovered that Miguel Trelawney had opened his eyes and was looking at him.

  * * *

  Dowland stood stockstill for a moment, hardly daring to believe it. Then, quietly, he unbuckled the harness again, and let it down to the floor. The eyes of the big man on the couch seemed to follow the motion, then shifted slowly up toward the ceiling of the room, and closed again.

  "Trelawney," Dowland said softly, without moving.

  Miguel Trelawney made a deep, sighing sound, turned on his side and lay quiet, his back now to Dowland. A few seconds later, Dowland was looking down at him from the other side of the couch.

  It might have been only a momentary thing, a brief advantage medic had gained in its invisible struggle with a process which would still end in death. But he couldn't be sure. The eyes remained closed, the pulse was weak and unsteady. Dowland thought of injecting a stimulant into Trelawney, and discarded the idea immediately. Medic manufactured its own stimulants as required, counteracted any others. Even the effects of the quiz-drug would be reduced by it, but not enough to keep Dowland from getting any answer he wanted—provided Trelawney's mind cleared for only three or four minutes of lucidity.

  There was no way of knowing when such a period of lucidity might develop. But now that the man had appeared to awaken, the possibility that it would happen within the next hour or two became a very definite one.

  Dowland stood briefly in scowling indecision. The next hour or two could also see him nearly down the side of the mesa, depending on the difficulties of the descent . . . but there was no real choice. It was a gamble either way again; if Trelawney didn't awaken, the other gamble remained. . . . How long, at most, could he afford to delay?

  Leaving YM out of the calculation, since it couldn't be calculated, he had only the arrival of the Freeholder Troopers to consider. There was no apparent possibility that any sizable party could appear before daybreak, but there was an even chance they would be there around that time. When they came, he must either be in communication with the Solar Police Authority or far enough away from Lion Mesa to be able to avoid detection. . . .

  Four hours should be enough to give him a reasonable safety margin. He had till midnight, or a little later.

  Dowland pulled a chair up to the side of the couch and sat down. The night wasn't quiet.

  The hogs squalled occasionally, and the wind still seemed to be rising. In spite of his efforts to avoid unsettling lines of thought, the nightmarish quality of the situation on the mesa kept returning to his mind and wasn't easily dismissed. The past—the past of over half a million years ago—had moved close to the present tonight. . . . That was the stubborn, illogical feeling—and fear—which he couldn't entirely shake off.

  * * *

  Half an hour later, Miguel Trelawney began breathing uneasily, then stirred about, but lapsed again within seconds into immobile unconsciousness.

  Dowland resumed his waiting.

  His watch had just told him it was shortly before eleven-thirty when he heard the shots. They were three shots—clear, closely spaced cracks of sound, coming from a considerable distance away. Dowland was out of his chair with the second one, halfway down the dark entry hall as he heard the third. He opened the door at the end of the hall just wide enough to slip through, moved out quickly, and closed the door behind him to keep the glow of light from the living room from showing outside.

  As the door snapped shut, there were three more shots. A hunting rifle. Perhaps two miles to the north . . .

  * * *

  Dowland stood staring up toward the wind-tossed line of the forest above the ranch area. Who was up there on the mesa—and why the shooting? Had the Troopers managed to get some men in by air? What would they be firing at?

  Signal shots, he thought then. And a signal to the ranch, in that case . . . Signaling what?

  With that, another thought came, so abruptly and convincingly that it sent a chill through him.

  Doctor Paul Trelawney . . .

  Paul Trelawney, not in the laboratory building—as Jill had surmised. Gone elsewhere, now returned. And, like his brother, returned to a point other than the one from which he had left.

  A man exhausted and not sure of where he was on the big tableland, an injured man—or perhaps one weakened by radiation sickness—such a man would fire a gun in the night to draw attention to himself. To get help.

  Minutes later, Dowland was headed in the direction from which the shots had come, carrying one of hi
s own rifles, along with the police gun. It was very unlikely he could get close enough to Trelawney—if it was Trelawney—to be heard approaching; but once he reached the general area of the shots, he would fire the rifle, and wait for a response. In the forest, the wind was wild and noisy, and the going was as rough as he had suspected it would be. Moonlight flowed into the open rocky stretches occasionally, and faded again as clouds moved on overhead. Among the trees he could barely see his way and had to advance more slowly.

  He came presently to a wide, smooth hump of rock shouldering up through the timber, and stopped to check the time. Twenty-five minutes had passed since he left the area of the house. If he had calculated correctly, the shots should have come from approximately this point. He moved somewhat cautiously into the open—a man waiting for help would think of selecting a place where he could be easily seen; and this could be the spot Paul Trelawney had chosen. And Trelawney, armed with a gun, might react rather abruptly if he saw a stranger approach.

  But the ridge lay empty under the moon, stretching out for over a hundred yards to right and left. Dowland reached its top, moved on among the trees on the north side, and there paused again.

  A feeling came, gradually and uneasily, of something wrong around here. He stood listening, unable to define exactly what was disturbing him; then a fresh gust of wind whipped through the branches about him, and the wrongness was on the wind—a mingled odor, not an unfamiliar one, but out of place in the evergreen forest, on this rocky shelf. A breath of warm darkness, of rotting, soft vegetation—of swamp or river-bed. Dowland found his breathing quickening.

  Then the scent faded from the air again. It might, he was thinking seconds later, have been a personal hallucination, a false message from nerves overexcited by the events of the night. But if Paul Trelawney had returned to this point from a distant time, the route by which he had come might still be open. And the opening not far from here. It was a very unpleasant notion. Dowland began to move on again, but in a slow and hesitant manner now.

  Another five minutes, he thought. At the end of that time, he certainly must have covered the distance over which the wind had carried the bark of a rifle—and should, in fact, be a little to the north of Trelawney on the mesa. If there were no further developments by then, he would fire a shot himself.

  The five minutes took him to another section of open ground, more limited than the previous one. Again an outcropping of weathered rock had thrust back the trees, and Dowland worked his way up the steep side to the top, and stood looking about. After some seconds, the understanding came suddenly that he was delaying firing the rifle because of a reluctance to reveal his presence in these woods. With an abrupt, angry motion he brought up the barrel pointing it across the trees to the north, and pulled the trigger.

  * * *

  The familiar whiplash of sound seemed startling loud. An instant later, there was a series of unnerving crashing noises in the forest ahead. Apparently some large animal had been alarmed by the shot. He heard it blundering off for a few hundred yards; then there was silence, as if it had stopped to listen. And then there was another sound, a deep, long cry that sent a shiver through his flesh. It ended; and the next thing that caught his attention was a glimpse of something moving near the edge of his vision to the left, just above the forest. His head and eyes shifted quickly toward it, and he found himself staring after a great shadowy thing flapping and gliding away over the tops of the trees. It disappeared almost immediately behind the next rise of ground.

  Dowland still stared after it, his mind seeming to move sluggishly as if unwilling to admit what he had seen was no creature he had ever heard about. Then it occurred to him suddenly that Trelawney had not yet responded to the signal shot; and almost with the thought, he grew aware of a renewed disturbance in the forest before him.

  This one was much less loud than the other had been. For a moment, Dowland thought it was being caused by the wind. But the noises continued; and in a few more seconds it became obvious that something—something that seemed to be very large indeed—was moving among the trees and approaching the open area. By that time, it wasn't very far away.

  Dowland turned, his mouth working silently, and slipped down the south side of the big rock hump, making no more noise than he could help. Already the trees were shaking on the other side of the rock. He ducked, crouched, into a thick mass of juniper branches, pushed through them, and made his way quickly and quietly deeper among the trees. This new thing, whatever it was, must also have heard the shot. It might check when it reached the open area and, when it discovered nothing to arouse its further curiosity, move off again.

  But it didn't. Glancing back through the trees, Dowland had an indistinct glimpse of something very tall coming swiftly around the shoulder of rock. He turned, scuttled on under the branches, and a moment later, there was a tremendous crashing at the point where he had left the open ground. The thing was following him down into the woods.

  Dowland turned again, gasping, dropped the rifle, and pulled the IPA gun from his pocket. The thickets splintered; a towering shape came through them. He drove three shots at it, had the approximate sensation of being struck across the head with an iron bar, and felt himself fall forward. He lost consciousness before he hit the earth.

  * * *

  When he opened his eyes, his first thought was that he should be feeling a king-sized headache. He wasn't. He was lying face down on moist forest mold. There was a very dim predawn light about. So several hours must have gone by since . . .

  Dowland stiffened a moment, then turned his head very slowly, peering about. After a moment, he pushed himself quietly up on hands and knees. The trees before him shifted uneasily in the wind. Farther on, he could make out part of the hump of rock on which he had stood and fired a shot to draw Trelawney's attention. Between, the ground looked as if a tank had come plowing into the forest. But there was no giant shape lying there.

  So his three shots hadn't brought it down. But it had gone away—after doing what to him?

  Dowland saw the IPA gun lying beside him, picked it up, and got slowly to his feet. He ran a hand experimentally over his head. No lumps, not even a feeling of tenderness . . . He would have sworn that the crack he'd felt had opened his skull. He looked about for the rifle, saw it, picked it up, and went over to the area where the trees had been tossed about.

  There was a trail there—a very improbable trail. He studied it, puzzled and frowning. Not the tracks of an animal. If it had been more regular, such a track conceivably might have been laid by a machine moving along on a very wide smooth roller. There were no indications of any kind of a tread. As it was, about all he could say now was that something very ponderous had crushed a path—a path varying between approximately eight and fourteen feet in width—through the woods to this point, and had then withdrawn again along a line roughly parallel to its approach. . . . And he could say one other thing about it, Dowland added mentally. The same ponderous entity could knock out a man for hours, without apparently injuring him, or leaving any sign of how he had been struck down.

  The last sounded more like a machine again; a machine which was armed in some mysterious manner. When his shot had flushed up the big flying creature during the night, he'd almost been convinced that some monster out of Terra's distant past was there on the mesa. Those two things just didn't jibe.

  Dowland shook his head. He could think about that when he had more time. He'd lost—he looked at his watch—a little less than four hours. In four hours, a large number of things might have happened in the ranch area, with only the one partly attractive possibility among them that somebody had managed to get into the laboratory and shut off the YM flow.

  * * *

  He started back at a cautious trot. Downhill and with the light strengthening gradually, covering ground was considerably less of a problem than it had been during the night. The wind hadn't let up; it still came in wild, intermittent gusts that bent the trees. Now and then a cloud of du
st whipped past, suggesting that the air over the desert was also violently disturbed. And it might very well be, Dowland thought, that YM could upset atmospheric conditions in an area where it was active. Otherwise, if there was anything abnormal going on in the forest about him, there were no detectable indications of it.

  He came out presently on a ridge from where the ranch area was in view. It lay now approximately a third of a mile ahead. In the dim light, everything seemed quiet. Dowland slowed to a walk.

  He might be heading into an ambush down there. Jill Trelawney could, at most, be beginning to wake up from her drugged sleep and for another hour or so she would be too confused and groggy to present a problem. But others might be at the ranch by now; Paul Trelawney or a group of Carter's Troopers. And whether Jill was able to give them a coherent report or not, any of the Freeholder conspirators would discover very quickly that somebody who was not a member of their group had been there before them; they would anticipate his return, be on the watch for it. Dowland left the direct line he had been following, and headed east, moving with constantly increasing caution. On that side, the forest grew closest to the ranch buildings, and he remembered noticing a hedge-like thicket of evergreens just north of the cleared land. He could make a preliminary check of the area from there.

  He was within a hundred and fifty feet of the point when he discovered just how healthy the notion of a preliminary check had been. A man was lying in the cover of the evergreens Dowland had been thinking about, head up, studying the ranch grounds. He wore an antiradiation suit of the type Dowland had found in the storeroom; a heavy rifle lay beside him. His face was in profile. It was smeared now with the sweat and dirt the AR field had held in, but Dowland recognized the bold, bony features instantly.

  He had finally found Doctor Paul Trelawney.

  * * *

  It took Dowland over eight minutes to cover the remaining distance between them. But the stalk had eminently satisfactory results. He was within a yard of Trelawney before the Freeholder became aware of his presence. The IPA gun prodded the man's spine an instant later.
