Built Upon the
Sands of Time

MICHAEL F. FLYNN

Michael Flynn’s first story appeared in Analog in 1984, and, according to the Encyclopedia of Science Fiction, he “soon became identified as one of the most sophisticated and stylistically acute 1980s Analog regulars.” A statistician by profession, in his fiction Flynn is interested in technology and the people who work with it. So he’s a perfect match for the traditional image of the hard SF writer, except that his interest in characterization goes deeper than most. His first novel was In the Country of the Blind (1990), now revised and reissued in hardcover in 2001; his second novel was Fallen Angels (1991) in collaboration with Larry Niven and Jerry Pournelle. His third, The Nanotech Chronicles (1991), is a series of linked stories. His major work of the 1990s began with Firestar (1996), Rogue Star (1998), Lodestar (2000) and Falling Star (2001), four volumes in an ongoing future history, done in a very Heinleinesque manner. Many of his best stories, including the excellent novella “Melodies of the Heart,” are collected in The Forest of Time and Other Stories (1997).

“Built Upon the Sands of Time” is Flynn the Analog writer doing a bar story about scientists and ordinary people. It is notable for its characterization, humor, scientific twist, and also as a contrast to the Nancy Kress story “To Cuddle Amy.” There were a number of excellent SF stories about parents and parenting this year and this is also one of the best of that strain.

A wise man once said that we can never step in the same river twice. A very wise man, indeed; because by that he did not mean we should refrain from bathing, as some half-wits at the Irish Pub have suggested, but that times change and the same circumstances are never fully repeated. You are not the same person you were yesterday; nor am I.

But perhaps that old Greek was not half so wise as he thought. Perhaps you cannot step into the same river even once; and you may not be the same person yesterday as you were yesterday.

 

Friday nights at the Irish Pub are busier than a husband whose wife has come home early. When The O Neil and myself arrived, the neighborhood crowd was there bending elbows with the University folks from down the street and making, as they like to say, a joyful noise. It was so busy, in fact, that Hennesey, O Daugherty’s partner, had joined him behind the bar and even so they were barely keeping ahead of the orders. There were another dozen or so boyos in the back room, watching the progress of the pool table and providing encouragement or not to the players, as the case might be. The O Neil placed his challenge by laying a quarter down on the rail and promised to call me in for a game as soon as he won the table. Then he set himself to study the opposition. Seeing as how the quarters were lined up on the rail like so many communion children, I knew it would be a long, sad time before I held a cue in my hand, so I took myself back out to the bar.

O Daugherty Himself was a wise man, for he had saved a stool for my sitting and, more quickly than I could order it, had placed a pint of Guinness before me. O Daugherty is a man who knows his manners; and his customers, as well. After a polite nod to the man on my right, whom I did not know, I occupied myself with the foamy stout.

Hennesey was a contrast to his partner. Where O Daugherty was short, dark, and barrel-chested, Hennesey was tall, fair, and dour, one of the “red-haired race” from the North of Ireland. His long, thick, drooping face seemed always on the verge of tears, though never quite crossing over into the real thing. His shoulders were stooped because, tall as he was, he had to bend over to communicate with the common ruck. He gave me a smile, which for him consisted of raising the corners of his mouth from the vicinity of his chin to a nearly horizontal position. I hoisted my own mug in reply.

But no sooner had I taken the first, bitter sip than I heard Doc Mooney, on the far side of the oval bar, complain. In itself, this was no unusual thing, since complaint is the blood and spit of the man. But the nature of his complaint was more than a little out of the ordinary.

“Which of ye spalpeens,” he cried, “has taken my jawbone?”

Danny Mulloney, sitting two stools to his left, looked at him. “Why, no one, you omadhaun, seeing as how you’re still flapping it.”

Doc gave him the squint-eye. “It’s not my own jawbone I’m speaking of, ye lout; as you would know if you applied what little thought you have to it; but the jawbone we keep at the medical school for purposes of demonstration. I had put it in my pocket when I left for the day.”

“Ah,” said Danny with a sad shake of his head, “and I would hate to be your wife, then, after turning out your pockets for the laundering. Sure, a pathologist should never take his work home with him.”

There was a ripple of laughter at our end of the bar. I confess that I smiled, myself, though it is my constant purpose never to encourage the wit of Danny Mulloney.

Doc turned a shade darker and tapped the bar top with a stiff finger. “I had set it right there, and now it is gone. Someone has taken it.”

“You weren’t thinking of leaving it as a tip, Doc?” I asked, getting into the spirit of the thing.

Doc gave me a look of betrayal. Et tu, Mickey? But Himself spoke up, a twinkle in his eye. “It would depend, I’m thinking, on how many teeth were yet in the jaw. Placed under my pillow, it might draw a tidy sum from the wee folk.”

Hennesey only shook his head at the blathering of mortals. “Now, who would wish to steal such a thing?” he asked, contrabasso.

“Samson,” Danny suggested, “were there any Philistines about?” Danny being of a religious frame of mind, a Biblical example came most naturally to him.

Doc, who knows a little of Scripture himself, leaned past the poor man who sat between him and Danny and consequently had to listen to the argument with both his ears, and said sweetly, “Nor is it your own jawbone we’re speaking of.”

“There is too much foam,” said the man sitting between them.

Both Danny and Doc pulled away, puzzled at the nonce of the sequitur. Himself reared up. “Too much foam, d’you say? Why, I give honest measure; and the man who says I do not is a liar.”

The man blinked several times. “What? Oh.” He glanced at the sturdy glass mug before him. “Oh, no, I did not mean your fine beer. I was responding to this gentleman’s question concerning his jawbone. I meant the quantum foam.”

Hennesey scratched his jaw. “The quantum foam, is it? And that would be an Australian beer?”

“No. I mean the timelessness that came ‘before’ the Big Bang. We call it the quantum foam.”

O Daugherty drew a fresh mug and set it down with a flourish before the man. “Sure and it is worth the price of a good pint to hear what connection there might be between the Big Bang and Doc Mooney’s jawbone.”

Doc protested again, “It’s not my jawbone,” but no one paid him any heed.

“Well,” said the man, “not to the jawbone, but to the disappearance of the jawbone.” He seemed hesitant and a little sad. For a moment, he managed to make even Hennesey look cheerful. Then he sighed and picked up the mug. “It’s like this,” he said.

 

“My name is Owen fitzHugh. I am a physicist at the University, but my hobby has always been the oddities of the Universe. Quirks, as well as quarks, as a colleague of mine has remarked…

“One of these quirks is what I call ‘phantom recollections’ and ‘causeless objects.’ Non-Thomistic events, if you must have a fine philosophical name for it. Have you ever looked in vain, as your friend here, for an object you clearly recall having placed in a certain spot? Or, conversely, found small objects for which you cannot account? Or recalled telephone numbers or appointments that turned out not to exist?”

“I had a key on my key chain, once,” said Maura Lafferty, “that I did not recognize and that fit no lock that I own. I still have no idea where it came from.”

“I had a date one time with Bridey Lynch,” said Danny, “but when I called on her, she had no recollection of it.”

Doc made an evil grin. “Why, there is no mystery at all in that.”

FitzHugh nodded. “They are usually small objects or bits of information, these anomalies of mine. Usually, when we notice them at all, we ascribe them to a faulty recollection; but I’m a natural contrarian. I wondered: What if it is the Universe, and not ourselves, that sometimes forgets.”

Danny and Doc flanked the poor man with a bookend of skeptical looks. Danny, I was sure, believed in God’s Infallible Memory; while Doc reasoned from the predictability of Natural Law. Still their thoughts had come to rest in the same place. Himself shifted his apron and cocked his head in interest. “Now what might that mean?”

“History is contingent,” said fitzHugh.

Himself nodded. “Aye, so it is.” But Danny scratched his head. “If it is, I’ve never caught it.” Doc leaned past the unfortunate physicist once more.

“He said ‘contingent,’ not ‘contagious.’”

FitzHugh looked at Danny. “I should have said that history is a chain of cause-and-effect,” he said. “One event leads to others, and then to still others. Often, great events hinge on small occurrences.”

Wilson Cartwright, a history professor at the University, spoke up from the booth behind fitzHugh. “That’s gospel truth. In 1862, a Confederate courier lost a copy of Lee’s troop dispositions. Two Union foragers found them and McClellan managed—barely—to win the battle of Antietam, which gave Lincoln the opportunity to issue the Emancipation Proclamation. And when the news of the Proclamation reached England, the cabinet reversed its decision to intervene on the Confederate side. In consequence of which…”He lifted his drink in salute to the bar. “…my great-grandpappy became a free man.”

Hennesey nodded. “Da met me Ma in the same way. Another small chance—though the outcome was not so momentous as war and freedom. He was on the run—. This was during the Troubles, when the Big Fella and the Long Fella had their row—bad cess to ’em both—and Da, he found himself in on the wrong side. O Daugherty, you know what I’m speakin’ of, and enough has been said about that. Da took himself to the Waterford hills and, finding himself at a crossroads, tossed a coin. The shilling sent him to Ballinahinch, where me ol’ Gran was keeping a pub in those days and Ma waited tables. Now Da was not the man to pass a pub without a drop of the creature, so he stopped and…” The man’s long, doughy face turned a deep red. “…here I am. Had the shilling read tails, he was a dead man, for his enemies were waiting down the other road. As it was, what with one thing and another…” And he pointed with his drooping chin to the photograph on the wall opposite, where a far younger Hennesey and O Daugherty stood side by side in black-and-white, stern-faced splendor, arms crossed and legs akimbo before the newly opened Irish Pub.

Doc Mooney raised his pint. “I have always thought you an unlikely man, Hennesey.”

“But that’s just the point,” fitzHugh said. “ Everything is unlikely… and therefore fragile.”

“ ‘Fragile,’ ” said Himself. “A curious word.”

“Fragile,” said fitzHugh with an affirmative nod. “Because the slightest bump and….You see, the quantum foam is subject to sudden, spontaneous disturbances. These create ‘probability waves’ in the continuum that propagate down the time stream creating a new past. The old past is obliterated. As it was in the beginning, is not, and never more shall be.”

Himself scowled a bit at the altered quotation, but Danny Mulloney brightened, which is always a bad sign. “Do you mean to say,” he said. “Do you mean to say that all those dinosaur fossils and such might have been put in the ground only a few thousand years ago?”

FitzHugh blinked and looked thoughtful. “Certainly, it’s conceivable,” he said slowly. “Yes. Suppose that evolution originally followed a different course—perhaps those strange Burgess Shale creatures I’ve read of won out over our own familiar phyla, and after a time strange things stalked the Earth of sixty million years ago—things that never held the promise of man. Then, a bubble bursts in the foam and a probability wave ripples down the timeline—and now dinosaurs leave their bones in the mud instead of things with no names. So, yes, in one sense, this new past could have been laid down a few thousand years ago; but in another sense, once it had been laid down, it had always been there.”

Danny pursed his lips, for I do not think he had envisioned a different evolution when he raised his question. Meanwhile, a ripple of wisely nodding heads showed the incomprehension propagating around the oval bar. FitzHugh noticed and said, “Perhaps a sketch will clear it up.” He seized a napkin and immediately began to doodle on it. Sitting as I was on the far side, I could not see what he sketched and Hennesey, noting my frustration, waved me inside the Sacred Oval. “Here,” he said, handing me a bar apron. “ ’Tis a busy night and we can use the help.” Then he set off to the front end of the bar to tend to the raging thirst there.

Tying the apron, I stepped across in time to hear fitzHugh say, “This was the continuum in its original state.” I glanced at the napkin and saw he had written:

“Then, a quantum disturbance alters event A to event A*. A stray chronon—a quantum of time—emitted from the foam, strikes like a billiard ball.” He turned to Dr. Cartwright, who had left his booth to stand behind him. “Perhaps your Confederate courier, Wilson, doesn’t drop his packet.” He held up the napkin again.

The big historian looked thoughtful, and nodded. Maura Lafferty, who had also joined the little group at the back end of the bar, leaned over the man’s shoulder. “Why did you add the ‘D’?”

“Oh, time doesn’t stop just because there is a bit of redecorating going on,” fitzHugh said. “The present is… call it the ‘bow wave’ of the Big Bang, plowing through formlessness and leaving time in its wake. But behind it is coming the ‘bow wave’ of the new version, altering all the original consequences of A. When the wave front reaches B, event B ‘unhappens.’ Something else—call it G—happens instead.”

“Why G?” Danny asked, frowning over the sketch. “Why not call it B?”

“It doesn’t matter what he calls it, ye spalpeen,” said Doc Mooney.

FitzHugh grimaced. “Actually, it does. I don’t want to imply that B happens differently —because it might not happen at all.”

Cartwright bobbed his head. “That’s right. If McClellan hadn’t intercepted Lee’s orders, it wouldn’t have changed the outcome of Antietam. There wouldn’t have been a battle at Antietam. McClellan only attacked there because he had Lee’s orders. Without them, there would have been a different battle at some other time and place.”

I scratched my head. “So why didn’t you alter C, D and E?”

“Because the wave front hasn’t ‘caught up’ to them yet.” He busied himself at the napkin. “Here, this is then next quantum of time, the next parasecond.”

“You’ll notice that the original causal chain is still propagating itself, and event E has led to event F. But the revision is catching up. Change waves move faster than one second per second—just as water moves faster down a channel already dug than it does across virgin ground—but you really need two different kinds of time to talk about it intelligently. Eventually, the change wave reaches the present, merges into the original Big Bang wave, and the revision is complete.” He held the napkin up one last time.

“Even our memories are reconfigured,” he said. “The right ripple and… who knows? We might be sitting here discussing Lee’s victory.”

You might be,” said Cartwright dryly.

Doc Mooney rubbed his chin and frowned. “I see a problem,” he said. He spoke with a chuckle, as if he suspected his leg of being pulled. “If our memories are reconfigured, how could we possibly know the past was ever different?”

The shadow passed over fitzHugh’s face once more. “Normally…we wouldn’t.”

Doc Mooney slapped his forehead. “Now, I am an old fool. I had started to put the jawbone into my jacket pocket, then I laid it back on my desk.” Defiance flashed. “And it has been sitting back there in the lab, all along,” he insisted.

FitzHugh nodded with solemn fish-eyes. “Yes. Though perhaps not ‘all along.’ If at the very moment you laid the jawbone on the bar, a change wave ‘caught up’ with the present, you would have for a bare instant two conflicting memories. A fragment of the original memory can survive and you sit here at ‘L’ remembering a bit of ‘F,’ instead of ‘K.’ The French have a word for it…”He snapped his fingers, searching for the word.

Merde?” suggested Doc innocently.

Déjà vu?” said Maura.

FitzHugh shook his head. “No. Déjà vu is when the change wave does not affect your own personal history, so instead of a fossil memory, you have an instant of remembering the same thing twice.” He looked at each of us, and it seemed to me that his eyes held immeasurable loneliness in them. “That’s why these phantom memories almost always involve trivia.” He shrugged, looked off at the corner. “Only an idle fancy. Who can say?”

Himself lifted fitzHugh’s now-empty mug and cradled it in his hands. He gave the physicist an intent look. “ Almost always,” he said, with a suggestive pause at the end.

FitzHugh shook his head and gestured at the mug. “An-other, please.”

“Perhaps,” said Himself, “it would be better if you let it pour out instead of in.”

(“What’s he mean?” Danny asked. “Wisht,” said Doc.)

Someone put “The Reconciliation Reel” on the juke box and fitzHugh winced as the wild skirling of whistles and fiddles filled the room. Some of the old neighborhood shouted Hoo! and began to clap their hands. “You’ll think I’m a fool. Deluded.”

Himself shrugged. “Does it matter if we do?”

“Sure,” said Doc Mooney, “we all think that Danny here is a deluded fool; but that doesn’t stop me from buying him a beer now and then.”

Danny, who could be quick on the uptake when the stakes were high, held his mug out to me and said, “You heard him.”

Sure, it is not often that Doc is hoist by his own petard, but he had the good grace to accept it cheerfully. While I filled Danny’s mug, fitzHugh looked on some inner place in his soul.

“You see,” fitzHugh said finally, “the brain stores memories both holographically and associatively. Because the memory is a hologram, one may recapture the entirety from a surviving fragment; and because they are ‘filed’ associatively, one recovered memory may lead to others. These shards of overwritten memories lie embedded in our minds like junk genes in our DNA, an explanation perhaps for stories of ‘past lives’; for false memory syndrome; or for inexplicable fugues or personality changes or…Or….” He paused again and shuddered. “Ah, God, what have I done?”

“Something,” O Daugherty suggested, “that needs a hearing.”

“From the likes of you?”

Himself took no offense. “From the likes of us,” he agreed, “or the likes of Father McDevitt.”

FitzHugh bowed his head. There had been fear in his eye, and sorrow, and despair. I wondered what odd confession we were about to hear, and ourselves with no power to bind or loose. Maura placed a hand on his arm. “Go on,” she urged. Cartwright rumbled something encouraging and Danny had God’s grace to keep his mouth shut.

Finally, fitzHugh drew a shuddering breath and blew it out through pursed lips. “A man cannot be responsible for something that never happened, can he?”

Himself shrugged. “Responsibility is a rare thing in any case: a bastard child, often denied.”

“It started with a dream,” fitzHugh said.

“Such things often do. And end there, too.”

“I’m not married,” fitzHugh said. “I never have been. There have been women from time to time, and we get along well enough; but there was never one to settle down with. Always it was too early to wed; until it became too late.”

“It’s never too late,” O Daugherty said, “when the right one comes along.”

FitzHugh’s smile was faint. “That’s the very problem, you see. It may be that she did, once. But…” Melancholy closed his face again and he inhaled a long, slow breath. “I live alone in a house in the middle of the block over by Thirteenth Street. It’s a little large for my needs and the neighborhood is not the best, but the price was right and I enjoy the puttering. There is a parlor, a dining room and kitchen, plus two bedrooms, one of which I use as an office. From the kitchen, a stairway leads to a rough, unfinished basement.

“Recently, I began to have a recurring dream. It always starts the same way. I walk through my kitchen to the back stairwell and go down, not to my own basement, but to another house entirely, where I walk past empty bedrooms, then a kitchen with dishes piled in the sink and a greasy patina to the stove, coming at last to a parlor containing comfortable, out-of-style furniture. There are large windows on two of the walls and, in the corner, a front door. The whole of it has such an air of dust and neglect and familiarity and long abandonment that I often find myself reduced inexplicably to tears when I awake.”

“It was your subconscious,” said Doc, “playing with that unfinished basement.”

FitzHugh gave a brief shake of the head. “I thought that, too; at first. Only…Well,the first few dreams, that was all. Just a silent walk through an empty house accompanied by a feeling of loss, as if I had had these disused rooms all along, but had forgotten about them. Once, I reached the front door before waking up, and stepped outside. An ordinary-looking neighborhood, but no place I’ve ever seen. The house sat on a slight rise on a corner lot. Not much traffic. If I had to guess, I would say a residential neighborhood in a medium-big city, but somewhere off the major thoroughfares. I travel a great deal, going to conferences and such, but I have never identified that city.”

He looked deeply into his ale while the rest of us waited. “The dream had a curious air to it. It felt like a memory more than a dream. Maybe it was the dirty dishes in the sink, or the out-of-date furniture in the parlor.” Another quirky smile. “If a dream-world, why so drab and ordinary a one?”

I left the group to answer an urgent call at the front end of the bar, where a shortage of brew threatened several collegians with imminent dehydration. When I returned to the discussion, fitzHugh was answering some question of Doc Mooney’s.

“…so the more I thought about it and puzzled over it, the more real it grew in my mind. I remembered things I never actually saw in the dream. It seemed to me that the sink ought to have separate hot and cold water faucets. And that upstairs there would be an office and a sewing room and another bedroom. So you see, the details had the texture of memory. How could I remember those things unless they were real?”

Doc pulled the squint-eye like he always does. I think he still suspected some elaborate joke at his expense. “Imagination can be as detailed as memory. Your dream left blanks and you began to fill them in.”

FitzHugh nodded. “That’s an answer I yearn for. If only I could embrace it.”

“What happened next?” Himself prompted. “There must be more to it than you’ve told to account for such a melancholy.”

The physicist drew a deep breath. “One evening, reading at home, I became acutely aware of the silence. Now I am a man that likes his solitude and his peace and quiet; but just for a moment the silence seemed wrong, and I wondered, What’s he up to?

“Who?” asked Danny. “What was who up to?”

FitzHugh shook his head. “I didn’t know, then. But I glanced at the ceiling as I wondered, even though there is nothing up there but a crawlspace and storage. And then I heard a woman’s voice.”

“A woman, was it?” said Himself. “And saying what?”

“I don’t know. I couldn’t make out the words, only the tone of voice. I knew that I had been addressed, and inexplicably my heart both soared and sank. I can’t explain it any other way. It was as if I had been yearning for that voice and dreading it, all at once.

“Well,” he continued, “associative memory means that one recovered memory can lead to others; and having found a fragment of one hologram, other fragments began to surface in my mind. I had only to close my eyes and imagine the phantom house. With each return, it became more real, and the conviction grew that I had lived there at one time, and not alone. Voices—there were two of them—grew more distinct. Often angry, but not always. Once, I’m embarrassed to say, whispering a sexual invitation. And then, one day, I saw her.”

He lifted his mug to his lips, but it hovered there without him drinking as he gazed into the dark, reflective surface. “I was puttering in the parlor, sanding down some woodwork in order to stain it. It was the sort of mechanical task that allows the mind to wander. And so mine did, until it seemed to me that I was in the kitchen of my ‘secret house,’ drying dishes with a towel. A tall, straw-haired woman was standing beside me washing them in the sink. She had the nagging near-familiarity of a once-met stranger. Perhaps I had seen her at a party in college and I never got up the nerve to walk over and introduce myself—only maybe, once, I did. I knew she was angry because she would shove the dishes into my hands in that silent-aggressive way that women sometimes use. She bore the harried look of someone once very beautiful but for whom beauty had lately become a chore. No makeup. Hair cropped in the simplest, most ‘practical’ style. Perhaps she blamed the me-that-was. Later, I remembered cutting remarks. She could have been this, or she could have married that. I don’t know why she kept slipping such hurts into our conversation…”He smiled ruefully. “But this first time, she turned to me and said very distinctly, ‘You have no ambition.’

“I was so startled that I snapped out of my daydream, and there I was, back in my own parlor.” He grimaced, ran a finger up and down the condensate on the outside of his glass. “Alone.”

“It’s only natural,” said Doc Mooney, “that a man living alone might grow wistful and imagine a married life he never had.”

FitzHugh laughed without humor. “Then why imagine such an unpleasant one?”

“Because you need to feel that you made the right choice.” “You’re a psychiatrist, then, and not a pathologist?” The tones were sarcastic and Doc flushed red. FitzHugh fell into a brown study, and fixed his eyes on the far wall. The rest of us, supposing the story had come to an unsatisfying conclusion, went about our own affairs: O Daugherty and myself to filling glasses and the others to emptying them, which division of labor made for an efficient process. Once or twice, I glanced at fitzHugh, noted his unfocused eyes, and wondered on what inner landscape he gazed. There were tears in the rims of his eyes. When he lifted his glass to me and signalled, I gave Himself a look and he gave me the high sign, so I switched fitzHugh’s drink to a non-alcoholic beer. I don’t think the man ever noticed.

“I had a son,” he told me when I handed him the freshened glass. No one spoke. Doc, from wounded pride; Danny, because of a firm headshake I gave him.

“A son, was it?” said Himself. “Sure, that’s a comfort to a man.”

FitzHugh made a face. “Lenny was anything but a comfort. Sullen, secretive. Seldom home, even for meals. Lisa blamed me for that, too.”

“He was a teenager, then.”

FitzHugh started and a rueful smile curled his lips. “Yes. He was. Is that normal behavior for that age? For the sake of other parents, I hope not. I’ve remembered flashes of him mouthing off, and once or twice I’ve even heard echoes of the foul words he used. I’ve another memory of a policeman standing in the front door holding Lenny by the arm and lecturing me.” He sighed. “Sometimes I wished we had never met, Lisa and I; and that I had married someone else and had different children; that, well…that everything had turned out better than it had.”

“Then it was good fortune,” I said, “that some bubble in the foam erased it.”

FitzHugh was a big man; not muscular exactly, but not frail-looking, either. Yet, he gave me a desolate look and laid his head on his arms and began to weep. O Daugherty and myself traded glances and Wilson Cartwright said, “I know where he lives. I’ll drive him home.” FitzHugh raised his head.

“Sometimes, I remember other things. Huddled over a kitchen table with Lisa, planning a future full of hope. A young boy bursting with laughter showing me a horse he had modeled out of clay. A camping trip in the Appalachians. Holding hands in a movie theater. Fleeting moments of simple pleasures. The joy had all leaked out, but once upon a time… Once upon a time, there had been joy.”

A wretched tale, for who among us has not known friend or family in a like situation? Sure, the wine may turn to vinegar in the bottle. And yet, who can forget how sweet it once tasted?

Himself nodded as he wiped a glass clean. “Are you ready to tell us now?”

FitzHugh grunted, as if struck. His eyes darted about our little group and found me. “It was no chance bubble,” he said, shaking his head sadly.

That startled me. “Then, what—?”

“I don’t know what sort of research my dream-self was doing. I recall enough tantalizing bits to realize it was down a different avenue than I’ve explored. But I do remember one especially vivid dream. I had built a chronon projector.”

Doc Mooney snorted, but Himself only nodded, as if he had expected it. Maura Lafferty wrinkled up her forehead and asked, “What’s a chronon projector?”

Frustration laced the physicist’s voice. “I’m not sure. A device to excite time quanta, I think. Into the past, of course. There’s nothing but formlessness futureward of the bow wave. Perhaps I had some notion of sending messages to warn of tornados or disasters. I don’t know. The projector was only a prototype, capable only of emitting a single chronon to a single locus. Enough to create a ripple in the pond; not enough to encode a message.” He upended his mug and drained it and set it down hard on the bar top. “Call it a ‘cue stick,’ if you wish. Something to send a billiard ball into the packed chronons of yesterday and start random ricochets of cause and effect.

“Yesterday, I had no classes to teach, so I stayed home to paint my dining room. I was thinking about mutable time; and I had my hand raised, so.” And he held his right hand just before his face. “There must have been some congruence of my train of thought and my posture, because in that instant I was standing in a lab before some great machine and my hand was gripping a switch, and I remember… Lisa and I had had an argument over Lenny, and I remember…I remember thinking that if I projected the chronon to the locus when Lisa and I met—to that time and place—I could create a ripple in the Dirac Sea, a disturbance in the probabilities and…It would all never have happened. None of it. The heartache, the bitching, the sullen anger—” He fell silent.

Himself prompted him. “And…?”

“And I awoke in a strange house, silent and alone.” He looked a long way off, seeing what, I do not know. Himself laid a hand on his arm.

“Wisht. What you had, you lost well before you threw the switch.”

FitzHugh grabbed O Daugherty’s hand and held it tight. “But, don’t you see? I lost all the hope, too. The memories of all the joy that went before; of a bright-eyed five-year-old whose smile could light the room. Of the possibility that Lisa and I might have worked it through.” He and O Daugherty exchanged a long, mutual look. “I owed her that, didn’t I? I owed it to her to try to solve our problems and not abolish them as things that never were.”

“Sure,” said Himself, “the bad comes mingled with the good; and if you excise the first, you lose the other as well.”

“There’s one thing I hold on to,” fitzHugh said.

“And what’s that?”

“That Lisa—whoever she is, from whichever college mixer or classroom where we never met—that in this revision, she’s had a better life than the one I gave her. I hold that hope tight as a shield against my crime.”

“Crime?” said Danny. “What crime was that?”

FitzHugh wiped his eyes with the sleeve of his jacket. “Lenny. He was never born. He’ll never have a chance to grow out of his rebellion and become a better person. Lisa is out there somewhere. Lisa has… possibilities. But there is no Lenny. There never was that bright-eyed five-year-old. There never will be. When I disturbed the time-stream, I wiped him out. I obliterated his life: all the hopes and fears and hates and joys… All the possibilities that were him. How is that so different from murder?”

The silence grew long.

Then fitzHugh pushed himself away from the bar and stood a little uneasily. Alarmed, Professor Cartwright took him by the elbow to steady him. FitzHugh looked at the rest of us. “But it all never happened, right? There oughtn’t be any guilt over something that never happened.”

It was Danny who spoke—hesitantly, and with more kindness than I had looked for. “Could you not build another of those chronon projectors and aim it back and correct what you did…?” But he trailed off at the end, as if he already suspected what the answer must be.

FitzHugh turned haunted eyes on him. “No. History is contingent. There’s no chance that a random disturbance to the revision would recreate the original. You may break the pack on a pool table with a well-aimed shot. You cannot bring the balls back together with another.” Cartwright guided him to the door, and the rest of us watched in silence.

“The poor man,” said Maura, when he had gone.

O Daugherty rapped hard on the maple counter top, as if testing its solidity. “So fragile,” he said, almost to himself. “Who knows if another time wave might be roaring down on us even now, a vast tsunami to wash all of us away?”

The O Neil returned from the back room with a glower on his face. “Ireland will get the Six Counties back before I get that pool table,” he said. “Let’s go on back to the house, Mickey.”

“I’ll catch you later,” I told him. “It’s a busy night and Himself can use the help as much as I can use the cash.”

The O Neil shook his head. “O Daugherty, you need to take on a partner, and that’s a fact.”

Himself shrugged and served him a parting glass of black Guinness. “Someday, maybe,” he said. Me, I glanced over at the photograph on the wall, where O Daugherty stood, arms crossed and legs akimbo, before his newly opened pub; and it seemed to me, though I don’t know why, that the picture was all out of kilter, as if something large were missing.
