"No noise, please," Dowland said softly. "I'd sooner not kill you. I might have to."
Paul Trelawney was silent for a moment. When he spoke, his voice was raw with shock. "Who the devil are you?"
"Solar Police Authority," Dowland said. "You know why I'm here."
Trelawney grunted. Dowland went on, "Why are you hiding out?"
"Why do you think?" Trelawney asked irritably. "Before showing myself, I was trying to determine the whereabouts of the man who fired a rifle within half a mile of me during the night."
So they had been stalking each other. Dowland said, "Why couldn't that person have been your brother or niece?"
"Because I know the sound of our rifles."
"My mistake . . . Do you have a gun or other weapon on you?"
"A knife."
"Let's have it."
Trelawney reached under his chest, brought out a sheathed knife and handed it back to Dowland. Dowland lobbed it into the bushes a few yards away, moved back a little.
"Get up on your hands and knees now," he said, "and we'll make sure that's all."
He was careful about the search. Trelawney appeared passive enough at the moment, but he was not a man too take chances with. The AR suit turned out to be concealing a tailored-in two-way communicator along with as many testing and checking devices as an asteroid miner's outfit, but no weapons. In a sealed pocket, obviously designed for it, was a five-inch atomic key. Dowland skid the heavy disk out with fingers that suddenly were shaking a little.
"Does this open your laboratory here?"
"Yes."
Dowland detached the communicator's transmission unit, and dropped it with the laboratory key into his pocket. "All right," he said, "turn around and sit down." He waited until Trelawney was facing him, then went on. "How long have you been watching the ranch?"
"About an hour."
"Seen anyone—or anything?"
Trelawney regarded him quizzically, shook his head. "Not a thing."
"I won't waste time with too many questions just now," Dowland said. "The laboratory is locked, and the machine you started in there apparently is still in operation. Your brother was found outside the laboratory yesterday morning, and may be dead or dying of internal radiation burns. He was alive and didn't seem to be doing too badly when I left him and Miss Trelawney in the house last night to go looking for you. I had to drug Miss Trelawney—she isn't a very cooperative person. She should still be asleep.
"Now, if I hadn't showed up here just now, what did you intend to do?"
"I intended to stop the machine, of course," Trelawney said. His expression hadn't changed while Dowland was talking. "Preferably without involving the Solar Police Authority in our activities. But since you've now involved yourself, I urgently suggest that we go to the laboratory immediately and take care of the matter together."
Dowland nodded. "That's what I had in mind, Trelawney. Technically you're under arrest, of course, and you'll do whatever has to be done in there at gun point. Are we likely to run into any difficulties in the operation?"
"We very probably will," Trelawney said thoughtfully, "and it's just as probable that we won't know what they are before we encounter them."
Dowland stood up. "All right," he said, "let's go. We'll stop off at the house on the way. I want to be sure that Miss Trelawney isn't in a position to do something thoughtless."
He emptied the magazine of Trelawney's rifle before giving it to him. They started down to the house, Trelawney in the lead, the IPA gun in Dowland's hand.
The house door was closed. Trelawney glanced back questioningly. Dowland said in a low voice, "It isn't locked. Open it, go on in, and stop two steps inside the hallway. I'll be behind you. They're both in the living room."
He followed Trelawney in, reaching back to draw the door shut again. There was a whisper of sound. Dowland half turned, incredulously felt something hard jab painfully against his backbone. He stood still.
"Drop your gun, Dowland."
Jill Trelawney stood behind him. Her voice was as clear and un-slurred as if she had been awake for hours. Dowland cursed himself silently. She must have come around the corner of the house the instant they went in.
"My gun's pointing at your uncle's back," he said. "Don't do anything that might make me nervous, Miss Trelawney."
"Don't try to bluff Jill, friend," Paul Trelawney advised him without turning his head. There was dry amusement in the man's voice. "No one's ever been able to do it. And she's quite capable of concluding that trading an uncle for an SPA spy would still leave Terra ahead at this stage. But that shouldn't be necessary. Jill?"
"Yes, Paul?"
"Give our policeman a moment to collect his wits. . . . This does put him in a very embarrassing position, after all. And I can use his help in the lab."
"I'll give you exactly three seconds, Dowland," Jill said. "And you'd better believe that is not a bluff. One . . ."
Dowland dropped his gun.
* * *
The two Trelawneys held a brief, whispered conversation in the living room. Dowland, across the room from them, and under cover of two guns now, couldn't catch much of it. Jill was in one of the radiation suits he'd brought in from the storeroom. Miguel was dead. He had still been unconscious when she woke up, and had stopped breathing minutes afterwards. Medic had done what it could; in this case it simply hadn't been enough. Jill, however, had found another use for it. Dowland thought the possibility mightn't have occurred to anyone else in similar circumstances; but he still should have thought of it when he left the house. As she began to struggle up from sleep, she remembered what Dowland had told her about medic, and somehow she had managed to inject a full ampule of it into her arm. It had brought her completely awake within minutes.
The murmured talk ended. The girl looked rather white and frightened now. Paul Trelawney's face was expressionless as he came over to Dowland. Jill shoved the gun she had put on Dowland into her belt, picked up Paul's hunting rifle, held it in her hands, and stood waiting.
"Here's the procedure, Dowland," Trelawney said. "Jill will go over to the lab with us, but stay outside on guard. She'll watch . . ."
"Did you tell her," Dowland interrupted; "to keep an eye out for something that stands twice as high as this house?"
Trelawney looked at him a moment. "So you ran into it," he said. "I was wondering. It's very curious that . . . well, one thing at a time. I cautioned her about it, as it happens. Now come over to the table."
Dowland remained standing beside the table, while across from him Trelawney rapidly sketched out two diagrams on a piece of paper. The IPA gun lay on the table near Trelawney's right hand. There might have been an outside chance of reaching it if one could have discounted Jill's watchfulness. Which, Dowland decided, one couldn't. And he'd seen her reload the rifle she was holding. He stayed where he was.
Trelawney shoved the paper across to him.
"Both diagrams represent our machine," he said, "and they should give you a general idea of what you'll see. This wheel here is at the far side of the console when we come in the door. The wheel is the flow regulator—the thing you have to keep in mind. There are scale markings on it. The major markings have the numbers one to five. Yesterday morning the regulator was set at five—full flow. Spin the wheel back to one, and the YM-400 that's been producing the flow goes inert. Is that clear?"
Dowland nodded. "Clear enough."
"After that," Trelawney remarked, "we may be able to take things a little easier."
"What's the quantity you're using in there?"
"No real reason I should tell you that, is there? But I will. The sixty-eight kilograms the Overgovernment's been grieving about are under the machine platform. We're using all of it." He grinned briefly, perhaps at Dowland's expression. "The type of job we had in mind required quantities in that class. Now, about yourself. We're not murderers. Jill tells me you can't be bribed—all right. What will happen, when this thing's settled, is that you'
ll have an attack of amnesia. Several months of your life will be permanently lost from your memory, including, of course, everything connected with this operation. Otherwise you won't be harmed. Understand?"
"I've heard of such things," Dowland said drily.
It wouldn't, however, be done that way. It was the kind of thing told a man already as good as dead, to keep him from making a desperate attempt to save himself. The Freeholders really wouldn't have much choice. Something had loused up their plans here, and if Dowland either disappeared or was found suffering from a sudden bout of amnesia, the IPA would turn its full attention on Terra at once. If he died, his death could be plausibly arranged to look like an accident or a killing for personal motives. These people were quite capable of sacrificing one of their group to back such a story up. And it would pass. Terra was under no more immediate suspicion than any other world. Dowland had been on a routine assignment.
* * *
There were a few brief preparations. Paul Trelawney checked the batteries in the radiation suits he and Jill were wearing, then exchanged his set for that of the spare suit. Dowland left his own AR field off for the moment. It was at least as adequate as the one developed by the Trelawneys' suits, and in some respects a much more practical device. But the suit batteries had an effective life of twenty-four hours, expending them automatically while the suits were worn. His field would maintain itself for a minimum of an hour and a half, a maximum of two hours. In this situation, Dowland wasn't sure how long he would have to depend on the field. A few more minutes of assured protection might make a difference.
He saw Trelawney studying the mountaineering rig on the floor; then he picked up the harness and brought it over to him.
"Here, put it on," he said.
"What for?" Dowland asked, surprised.
Trelawney grinned. "We may have a use for it. You'll find out in a minute or two."
They left the house by a back entrance. Clouds were banked low on the eastern horizon now; the first sunlight gleamed pale gold beneath them. In the west the sky was brown with swirling dust. Jill stopped twenty yards from the laboratory building and stood on the slope, rifle in hand, watching the men go on. At the door, Dowland switched on his AR field. Trelawney tossed the disk-shaped key over to him.
"Know how to use it?"
Dowland nodded.
"All right. After you've snapped it in and it releases again, throw it back to me. It may be the last one around, and we're not taking it into the laboratory this time. When the door starts moving down, step back to the right of it. We'll see what the lab is like before we go in." Trelawney indicated a thimble-sized instrument on his suit. "This'll tell whether the place is hot at the moment, and approximately how hot." He waved the IPA gun in Dowland's direction. "All right, go ahead."
Dowland fitted the key into the central depression in the door, pressed down, felt the key snap into position with a sharp twisting motion of its own, released his pressure on it. An instant later, the key popped back out into his hand. He tossed it back to Trelawney, who caught it left-handed and threw it over his head in Jill's direction. The disk thudded heavily into the grass ten feet from her. The girl walked over, picked it up, and slid it into one of her suit pockets.
The slab of metasteel which made up the laboratory door began moving vertically downward. The motion stopped when the door's top rim was still several inches above the level of the sill.
A low droning came from the little instrument on Trelawney's suit. It rose and fell irregularly like the buzz of a circling wasp. Mingled with it was something that might have been the hiss of escaping steam. That was Dowland's detector confirming. The lab reeked with radiation.
He glanced over at Trelawney.
"Hot enough," the Freeholder said. "We'll go inside. But stay near the door for a moment. There's something else I want to find out about. . . .
* * *
Inside, the laboratory was unpartitioned and largely empty, a great shell of a building. Only the section to the left of the entrance appeared to have been used. That section was lighted. The light arose evenly from the surfaces of the raised machine platform halfway over to the opposite wall. The platform was square, perhaps twenty feet along its sides. Dowland recognized the apparatus on it from Trelawney's diagrams. The central piece was an egg-shaped casing which appeared to be metasteel. Near its blunt end, partly concealed, stood the long, narrow instrument console. Behind the other end of the casing, an extension ramp jutted out above the platform. At the end of the ramp was a six-foot disk that might have been quartz, rimless, brightly iridescent. It was tilted to the left, facing the bank of instruments.
"A rather expensive bit of equipment over there, Dowland," Trelawney said. "My brother developed the concept, very nearly in complete detail, almost twenty-five years ago. But a great deal of time and thought and work came then before the concept turned into the operating reality on that platform."
He nodded to the left. "That's Miguel's coat on the floor. I wasn't sure it would still be here. The atomic key you were searching for so industriously last night is in one of its pockets. Miguel was standing just there, with the coat folded over his arm, when I saw him last—perhaps two or three seconds before I was surprised to discover I was no longer looking at the instrument controls in our laboratory."
"Where were you?" Dowland asked. "Six hundred thousand years in the past?"
"The instruments showed a fix on that point in time," Trelawney said. "But this was, you understand, a preliminary operation. We intended to make a number of observations. We had not planned a personal transfer for several more weeks. But in case the test turned out to be successful beyond our expectations, I was equipped to make the transfer. That bit of optimistic foresight is why I'm still alive."
What was the man waiting for? Dowland asked, "What actually happened?"
"A good question, I'd like to know the whole answer myself. What happened in part was that I suddenly found myself in the air, falling toward a river. It was night and cloudy, but there was light enough to show it was a thoroughly inhospitable river. . . . And now I believe"—his voice slowed thoughtfully—"I believe I understand why my brother was found outside the closed door of this building. Over there, Dowland. What does that look like to you?"
Near the far left of the building, beyond the immediate range of the light that streamed from the machine stand, a big packing crate appeared to have been violently—and rather oddly—torn apart. The larger section of the crate lay near the wall, the smaller one approximately twenty feet closer to the machine platform. Assorted items with which it had been packed had spilled out from either section. But the floor between the two points of wreckage was bare and unlittered. Except for that, one might have thought the crate had exploded.
* * *
"It wasn't an explosion," Trelawney agreed when Dowland said as much. He was silent a moment, went on, "In this immediate area, two space-time frames have become very nearly superimposed. There is a constant play of stresses now as the two frames attempt to adjust their dissimilarities. Surrounding our machine we have a spherical concentration of those stresses, and there are moments when space here is literally wrenched apart. If one were caught at such an instant—ah!"
To Dowland it seemed that a crack of bright color had showed briefly in the floor of the building, between the door and the machine platform. It flickered, vanished, reappeared at another angle before his ears had fully registered the fact that it was accompanied by a curiously chopped-off roar of sound. Like a play of lightning. But this was . . . .
The air opened out before him, raggedly framing a bright-lit three-dimensional picture. He was staring down across a foaming river to the rim of a towering green and yellow forest. The crash of the river filled the building. Something bulky and black at the far left . . . but the scene was gone—
The interior of the laboratory building lay quiet and unchanged before them again. Dowland said hoarsely, "How did you know what was going to happ
en?"
"I was in a position to spend several hours observing it," Trelawney said, "from the other side. You see now, I think, that we can put your mountaineer's kit to some very practical use here."
Dowland glanced across the building. "The walls . . ."
"Metasteel," Trelawney said, "and thank God for that. The building's sound; the stresses haven't affected it. We'll have some anchor points. A clamp piton against that wall, six feet above the console walk and in line with it, another one against the doorframe here, and we can rope across."
Dowland saw it, unsnapped his harness, fed the end of the magnerope through the eye of a piton, and twisted it tight. "Are we going together?" he asked.
Trelawney shook his head. "You're going, Dowland. Sorry about that, but this is no time for sporting gestures. The rope doesn't eliminate the danger. But if you find your feet suddenly dangling over the air of a very old time, you'll still stay here—I hope. If you don't make it across, I'll follow. We get two chances to shut Ymir down instead of one. All right?"
"Since you have the gun, yes," Dowland said. "If I had it, it would be the other way around."
"Of course," Trelawney agreed. He watched in silence then as Dowland rammed the threaded piton down the muzzle of the gun, locked it in position, took aim across the machine platform, and fired. The piton clamp made a slapping sound against the far wall, froze against it. Dowland gave the loose end of the rope a few tugs, said, "Solid," cut the rope, and handed the end to Trelawney.
The Freeholder reached up to set a second piton against the doorframe, fed a loop of the rope through it, and twisted it tight. Dowland slipped a set of grappling gloves out of the harness, pulled one over his right hand, tossed the other to Trelawney. "In case," he said, "you have to follow. Magnerope gets to be wearing on bare hands."
Trelawney looked briefly surprised, then grinned. "Thanks," he said. "Can you do it with one glove?"
