Thrice upon a Time

  To all at Del Rey Books—the other half of the team who never get mentioned on the cover.

  Prologue

  The digits, glowing bright red in the upper corner of the computer display screen, changed silently to count off the final seconds.

  00:05… 00:04… 00:03… 00:02… 00:01… 00:00.

  A symbol appeared below the clock-readout to confirm that the program had begun running. A moment later, the main area of the screen came alive to present the display:

  30 December 2009, 23:25:00 Hours.

  TEMPORAL RETROTRANSMISSION TEST NUMBER 15 Group 4, Sample 3.

  Transmission advance 60 seconds.

  END

  The elderly man sitting in front of the console gazed expressionlessly at the display for a second, and then tapped a pad on the touchboard array below the screen. A mild whine came from one of the racks of electronic equipment standing next to him; at the same time a hardcopy of the information on the screen slid smoothly from a slot and into the tray below. The screen went blank. The man took the hardcopy, ran his eye casually over it, then sat back in his chair to wait. In the upper corner of the screen, the clock-readout had reset to sixty seconds and begun counting down again.

  The man's body was tall, and his shoulders still broad and straight, but the hair that had once glinted jet-black was now white, and the beard jutting stubbornly from his chin had faded to gray. Remnants of flames that had once blazed bright still smoldered in the eyes looking out over the ruddy crags of his face, but the fire was beginning to give way to a fatigue accumulated over many long years of life.

  After a while he shifted his gaze to the fluffy black-and-white kitten lying curled up in the half-open, lower-most drawer of the desk that stood alongside his chair.

  "Aye, it's a strange pair we are, Maxwell, and that's for sure," he murmured. "Still at work here at an hour when any folks with a dram o' sense would long have been away to their beds. Enough's enough. We'll make this the last for tonight now."

  Alerted by the man's voice, the kitten opened a sleepy eye to look at him, and then glimpsed the reflex twitching of his own tail. He awoke, pounced back into the depths of the drawer, and began whirling in futile circles amid sounds of swishing fur and crumpling paper. A yellow plastic pushpin flew out in the confusion, bounced on the floor with a hollow clatter, and rolled away in a drunken curve around the base of one of the equipment cubicles. Maxwell's head appeared peering from the opening with ears erect and eyes following the rolling button like twin tracking-radars. Then the kitten cleared the side of the drawer in a bound, rounded the corner of the desk in an uncontrolled skid with all four paws flailing ineffectively at the shiny floor, reengaged forward drive suddenly, and scampered away in pursuit.

  A faint smile softened the corners of the man's mouth as he watched. Then he looked back at the screen in front of him. The countdown had almost reached zero.

  00:01… 00:00.

  A display similar to the previous one appeared. The man carefully compared the number contained in it with the one in the hardcopy record that he was still holding. They matched. He nodded slowly to himself. At that very moment, if the phrase retained any meaning at all in the strange realm of topsy-turvy logic that he had uncovered, a man was watching those same lines appear on that same screen for the first time—the gray-haired man who was sitting in that same chair, sixty seconds in the past.

  He hardcopied the second display, attached the copy to the first, added the sheets to a pile lying on the desk, and entered the details in a notebook lying open beside him. Then he closed the book and turned back to the console to begin the brief routine for shutting down the system.

  "Enough's enough," he repeated as he finished and rose from the chair. As he moved toward the door, the pushpin rattled back into sight from behind a part of the machine. The tip of a black-and-white nose poked round the base of a cubicle. Then, slowly, Maxwell's face slid fully into view closely followed by Maxwell, his body elongated low near the floor like a snake with legs. The kitten gathered himself to spring, then paused and looked up curiously as the man reached for the lightswitch.

  "Och, come on now," the man called. "There'll be time enough for that kind o' nonsense tomorrow. It's nearly tomorrow already as it is." Two saucer-eyes turned wistfully toward the pushpin and then up again before the kitten stood up and trotted for the doorway. "Aye, you're no' so bad for all your mischief, ye wee scallywag," the man said gruffly. He turned out the light, waited for Maxwell to leave the lab, and closed the door behind.

  The passage outside was bare, with plain, whitewashed walls rising up from a gray stone floor. At the end of the passage they came to a narrow wooden staircase leading up to a heavy oak door. The man waited again at the top of the stairs and held the door ajar while the kitten tackled the steps manfully, half leaping, half scrambling up one and then bunching himself for the next.

  They emerged from the doorway into a large, paneled hall, gloomy in the feeble light of the single lamp that had been left burning halfway along a corridor opening off the far side. The floor here was covered by deep, rich carpet. Vague shadows of portraits stared down from the walls, and the furnishings, most of which dated from the early twentieth century or before, were solid, well preserved, and dignified in keeping with their surroundings. A full suit of medieval armor stood impassively at the foot of a broad carved staircase that disappeared into deeper darkness above, where glints of reflected light traced ghostly outlines of Scottish claymores and battle axes mounted on the walls.

  The man flipped a switch to illuminate the stairs and began climbing slowly. Two circles of mirror-brightness were already staring back at him from the darkness just above the top step. "You'd no' be so nimble on your feet with seventy-two years on the wrong side o' ye, Maxwell," the man said. At the top of the flight he turned to follow the railed gallery that overlooked one side of the stairwell, and stopped outside one of the doors opening off the short passageway beyond. A shaft of light lanced across the floor as he pushed the door open.

  "We've done it, Maxwell," he murmured. "There can be no doubt about it now. It works, all right. We'll have to be telling Ted the good news first thing in the morning." He paused for a second. "And Murdoch, of course… It's time we were involving Murdoch in what's been going on." He nodded to himself. "Aye. Murdoch will be very interested indeed if I'm not very much mistaken."

  The door swung shut and plunged the household once more into gloom.

  Chapter 1

  Kennedy International Airport had shrugged off the snow that fell after Christmas, and was again a bustling oasis of business-as-usual amid the white-blanketed suburbs stretching along the southern Long Island shoreline. Steady processions of groundcars and mono-cabs flowed between the airport complex and Manhattan to the west, while overhead swarms of airmobiles arrived and departed like bees on never-ending foraging missions. From within the perimeter, a succession of Boeings, Lockheeds, and Douglases sailed vertically upward on the first stages of their suborbital trajectories through the ionosphere; higher above, arriving dots from Europe, Japan, Australia, and elsewhere slowly acquired shape as they dropped from the flawless blue that had come with the first day of the new year.

  In the Arrivals Concourse of the glass-fronted marble sculpture that constituted Terminal Three, Murdoch Ross stood among a group of waiting people and divided his attention between scanning the faces of the passengers streaming from Flight 235, just in from San Francisco, and taking in a few more lines of an article on graviton wave-mechanics featured in the current issue of Scientific American. He was in his late twenties, on the lean side of average for his medium height, and clean-shaven to reveal a fresh and healthy complexion. His eyes were bright an
d alert as they glanced up every few seconds from the magazine in his hand, and almost as dark as the wavy black hair above the collar of his overcoat.

  He saw the head of copper-colored hair protruding above the rest of the new arrivals at the same time as the head saw him. Its owner changed direction to wade obliquely through the river of humanity toward Murdoch. He was dressed in a dark-blue, open-necked shirt, navy windbreaker, and gray cords, and carrying a leather travel bag slung across one shoulder; he moved unhurriedly, but with a powerful, easy-going stride. Murdoch thrust the magazine into the pocket of his overcoat and grinned as they shook hands. It was like grasping a double-thick cut of spare rib that hadn't died yet.

  "Lee, great to see you again! It seems like a lot more than five months. I'm sorry about the short notice, but that's all I had myself."

  Lee Walker's mouth barely twitched, but his eyes came as near as they ever did to smiling. "Hi, Doc. You're right—it seems a lot longer. I guess that's the way things go." He heaved his bag onto his other shoulder and produced a pack of cigarettes from his windbreaker. "What time is it here? How long have we got before the flight leaves?"

  "It's on schedule—just over fifteen minutes."

  "Get my ticket fixed okay?"

  "You're all set."

  "Thanks."

  They began walking briskly toward the nearest escalator leading down to the automatic shuttle system that connected the airport terminals.

  "So," Murdoch said. "How are things back west? Dynasco going okay?"

  "Pretty good," Lee replied. "The checkout's finished, and the documentation's all done. I think they're pretty pleased with the whole deal."

  "Good."

  "In fact if you hadn't called, I'd have been coming on over to New York in a week or so anyway. How's it been looking?"

  "Promising. How about Tracey? Did you get her untangled at last?"

  "Yeah. It's all… 'untangled.' "

  An empty shuttle-car was waiting with doors open. They crossed the platform skirting the track at the bottom of the escalator and stepped inside.

  "Okay, so tell me more about it," Lee said. "You reckon your grandfather has actually done it—he can send information backward through time?" His face was creased into a frown and his tone skeptical.

  Murdoch nodded. "That's what he says."

  "But it's crazy. In principle it's crazy. What happens to causality?" Lee drew on his cigarette and blew a cloud of smoke toward the roof of the car. "What's he done exactly? How far has he sent it back?"

  "You know just about as much as I do," Murdoch told him. "He wasn't exactly generous with details when he called me either. He just said it worked and told me to get over there right away. He knows I've talked to you about it a lot, and figured it was about time you two met. So I called you. The rest you know."

  "But it's crazy," Lee insisted. "I never thought he'd get anywhere with it. If it's true, the whole of physics goes down the tubes. I mean—"

  "Save it," Murdoch said. "There's company on the way. Let's talk about it on the plane." A trio of businessmen approached along the platform and stepped into the car talking loudly about some company's market share or something or other. They were followed a few seconds later by a couple shepherding two young, tousle-haired boys. The car doors bleeped a warning and then closed, and the shuttle slid forward to rejoin the through-track, then accelerated smoothly into the tunnel that led to the next terminal on the circuit.

  Twenty minutes later they were sixty miles up over the mid-Atlantic at the apex of a shallow parabola that joined Kennedy to an artificial island constructed a few miles off-shore from Edinburgh in the Firth of Forth. The seats on one side of them were occupied by two pleasant but inquisitive middle-aged English ladies who plied them continually with questions about the States; on their other side sat a Bostonian who maintained a steady monologue on football despite their repeated proclamation of total ignorance of, and disinterest in, the subject. At no time during the thirty-five-minute flight did they get a chance to talk further about Murdoch's grandfather.

  Chapter 2

  "Did you ever hear of Bannockburn?" Murdoch asked over the muted humming of the car's engine.

  "Some kind of Scotch baron?" Lee guessed.

  "It's a place, not far off down that road on the left there. They had a battle there in 1314. The Scots had kicked the English out of the whole of Scotland except the castle at Stirling, which is the town we're just coming into. One of the English kings, Edward II, brought an army up to get them out, but he got wiped out by Bruce."

  "Scotch?"

  "Yes, except that's the stuff you drink. There was another battle here before that too, in 1297. That was when Edward I lost out. I guess the Edwards didn't have much luck around here."

  "I didn't know you went in for all this," Lee said.

  Murdoch shrugged. "Maybe it's my grandpa coming out in me. You know, I wouldn't mind moving over and living here somewhere one day. Look at the stonework in some of those buildings. I bet they were put up before anybody heard of California."

  They had decided not to use the local jet service from Edinburgh to the town of Inverness, just over one hundred miles to the north, since it would have made little difference to their total journey time. Instead they rented a groundcar at the island-airport and drove below the Firth to emerge on land some miles west of Edinburgh, heading toward the Scottish Central Lowlands. Since then, with the groundcar running automatically under remote guidance on the controlled main highway, they had turned northward to pass through Perth, the repeatedly besieged former capital, where they would cross the river Tay.

  Lee draped his arm along the lower ledge of the window and surveyed the scenery for a while. "It's a pretty country," he conceded at last, which from Lee was as near a eulogy as one was likely to get.

  Murdoch pursed his lips and nodded. "Now you know why I like coming over here whenever I can."

  "How come your father never talks all that much about it?" Lee asked. "I'd have thought that with a name like Malcom and being a generation nearer to it, he'd have been full of it. Are you the odd one out or something?"

  "More like the other way around," Murdoch replied, shaking his head. "He's the odd one. Grandpa was—still is—a theoretical physicist. His father was a mathematician. I guess I'm mathematical. As far as I know, my pa was the only one in the whole line for way back who couldn't balance a checkbook. Didn't stop him making money though."

  "That's probably the reason," Lee said. "Buy at sixty, sell at a hundred and make ten percent. Now I know why I can't read balance sheets. Ah well… I guess I'll never be rich." He fell silent for a moment, then went on, "Your father is definitely all-American. So if your grandfather's different, what's he like? Does he wear kilts and go around with daggers in his socks, and all that stuff?"

  "Dirks," Murdoch said, grinning. "No… not often anyway. Only on formal occasions. But you're right—he is pretty traditional. I guess that kind of thing tends to run through the Rosses too. Maybe that's why I like Scottish history."

  "And he's still that way after— How many years was your grandfather in the States before he moved back to Scotland?"

  "About forty, I think. But people like him don't change very easily. You'll see what I mean when you meet him."

  From Perth they followed the Tay valley into the Grampian Highlands, a fifty-mile-deep, storm-tossed giant's sea of granite waves quick-frozen by the winter snow. At the town of Kingussie in the valley of Strath Spey, Murdoch switched to manual drive and turned off the main Perth-Inverness highway and into the mountains of Monadhliath for the last leg of the journey to Glenmoroch. Within minutes the few remaining signs of the space age had disappeared completely. The road became a single track, winding its way carelessly among the feet of regiments of steep, boulder-strewn slopes that had fallen hopelessly out of step, and around frosty streams and rippling lochs, chattering and shivering with the winter cold. Woods of larch and Norwegian pine appeared at intervals, stretching fro
m the roadsides in irregular patches to form ragged skirts along the lower parts of the hills. Higher up, they thinned away or huddled into narrow gorges where they cowered beneath steep slopes of pebble screes and brooding buttresses of naked rock. Only the occasional farmhouse, bridge, or run of dry-stone wall remained as a reminder that the human race existed.

  They rounded a bend by one of the farms to find the road blocked by a miniature sea of sheep, which a dour farmer, a helper, and three tireless dogs were herding through a gate into one of the adjacent fields. Murdoch eased the car to a halt a few yards back from the scampering, bleating tide.

  Lee shook his head incredulously. "This can't be true," he said. Murdoch grinned and sat back in his seat to wait. For a while he watched the dogs. On his previous visits to Scotland he had come to admire the uncanny ability of sheepdogs to coordinate their movements and anticipate every gesture and whistle of command. Trained dogs enjoyed working and soon grew restless if deprived of it; like many people, animals could become addicted to the habit. During one of Murdoch's previous visits to Glenmoroch, a sheepdog belonging to Bob Ferguson, who owned a farm on the outskirts of the village, hurt a leg and was prescribed a week's rest by the vet, which meant no going up onto the hills. The dog occupied itself by herding chickens around the farmyard instead.

  Murdoch shifted his eyes to study the older of the two men, who was clad in a thick tweed jacket with trousers gathered into knee-length gumboots. He wore a flat peaked cap on top of graying, short-cropped hair. His face was the color of boiled lobster, lined and weathered, and below his bushy eyebrows his eyes burned keenly through slits narrowed by a lifetime's exposure to mountain winds and rain. It was a face, Murdoch thought, that, like the granite crags, had been carved by elements that had ruled the Highlands since long before the ancestors of the Picts and Celts drifted northward from England, or migrated across the sea from the lower valley of the Rhine. It was a face that belonged here, he told himself—just as a part of him, somewhere deep down inside, belonged here.
