In the years after he left Aston and split with Terr, Tom had found that he was able to put aside his inherent shyness, and go out in the big bad world of academic science, and smile and press the flesh with administrators and business suits and dinosaur heads-of-department, and develop a specialization of sorts which combined data analysis with radio astronomy. He knew he was able enough—somehow, his ability was the only thing about himself that he rarely doubted—and he found to his surprise that he was able to move from commercial development contracts to theoretical work to pure research without many of the problems of job security and unemployment which seemed to plague his colleagues. Or perhaps he just didn't care. He was prepared to go anywhere, do anything. He lived entirely in his head, as a brief woman friend had said to him. Which was probably true, for Tom knew that he was never that sociable. Like the essential insecurity of research work, he simply didn't let it worry him. It helped, often, that there was a ready supply of drinks at many of the conferences and seminars he attended—not perhaps in the actual lecture halls and conference suites, but afterwards, in the bars and rooms where the serious science of self-promotion went on. It helped, too, that at the back of it all, behind all the blind alleys and government cuts and flurries of spending, he had one goal.

It had surprised Tom that that first Martian landing should have had such a depressing effect on SETI research, when any sensible interpretation of the Drake Equation had always allowed for the fact that Earth was the only planet likely to harbor life in this particular solar system. Even he was disappointed, though, when the Girouard probe finally put the kibosh on any idea of life existing in what had once seemed like the potentially warm and habitable waters of Jupiter's satellite Europa. Still, the Principal of Mediocrity, which is that this sun, this solar system, this planet, and even the creatures which dwell upon it, are all common-or-garden variety phenomena, and thus likely to be repeated in similar form all over the galaxy, remained entirely undamaged by such discoveries, at least in Tom's mind. But in the mind of the general public (in that the general public has a mind to care about such things) and in the minds of the politicians and administrators who controlled scientific funding (ditto), it was a turning point, and began to confirm the idea that there really wasn't much out there in space apart from an endless vacuum punctuated by a few aggregations of rocks, searing temperatures, hostile chemicals.

Funnily enough, this recession of the tides in SETI funding worked in Tom's favor. Like a collector of a type of object d'art which was suddenly no longer fashionable, he was able to mop up the data, airtime and hardware of several abandoned projects at bargain prices, sometimes using his own money, sometimes by tapping the enthusiasm of the few remaining SETI-freaks, sometimes by esoteric tricks of funding. Now that the big satellite telescopes could view and analyze stars and their orbital perturbation with a previously unheard-of accuracy, a few other solar systems had come out of the woodwork, but they were astonishingly rare, and mostly seemed to consist either of swarms of asteroids and dust clouds or huge near-stellar aggregations of matter which would fuse and crush anything resembling organic life. So f_p in the Drake Equation—the fraction of stars to likely have a planetary system—went down to something like 0.0001, and n_e—the number of those planets which could bear life—fell to the even lower 0.0000-somethings unless you happened to think that life was capable of developing using a different chemical basis to carbon, as Tom, reared as he was on a diet of incredible starbeasts, of course did. f_l—the probability that life would then develop on a suitable planet—also took a downturn, thanks to lifeless Mars and dead Europa, and then as every other potential niche in solar system that some hopeful scientist had posited was probed and explored and spectrum analyzed out of existence. The stock of SETI was as low as it had ever been, and Tom really didn't care. In fact, he relished it.

He wrote a paper entitled "New Light On The Drake Equation," and submitted it to Nature, and then, as the last SETI journal had recently folded, to the Radio Astronomy Bulletin and, without any more success, and with several gratuitously sneering remarks from referees, to all the other obvious and then the less obvious journals. In the paper, he analyzed each element of the equation in turn, and explained why what had become accepted as the average interpretation of it was in fact deeply pessimistic. Taking what he viewed as the true middle course of balance and reason, and pausing only to take a few telling swipes at the ridiculous idea that computer simulations could provide serious data on the likelihood of life spontaneously developing, and thus on f_l, he concluded that the final N figure in the Drake Equation was, by any balanced interpretation, still in the region 1,000-10,000, and that it was thus really only a matter of time before contact was made. That was, as long as people were still listening …

He didn't add it to the versions of the paper he submitted, but he also planned to ask whoever finally published the thing to place a dedication when it was printed: For Terr. That, at least, was the simplest variant of a text he spent many wall-staring hours expanding, cutting, revising. But the paper never did get published, although a much shortened work, stripped of its maths by Tom and then of a lot of its sense by the copy editor, finally did come out in a popular science comic, beside an article about a man who was growing a skein of his own nerve tissue to a length of several hundred feet so that he could bungee-jump with it from the Victoria Falls. Still, the response was good, even if many of the people who contacted Tom were of a kind he felt reluctant to give out his e-mail, let alone his home, address to.

The years passed. Through a slow process of hard work, networking and less-than-self-aggrandizement, Tom became Mr. SETI. There always was, he tended to find, at least one member of the astronomy or the physics or even the biology faculty of most institutes of learning who harbored a soft spot for his topic. Just as Sally Normanton had done when he returned to Aston on that autumn when the air had smelled cleaner and different and yet was in so many ways the same, they found ways of getting him small amounts of funding. Slowly, Tom was able to bow out of his other commitments, although he couldn't help noticing how few attempts were made to dissuade him. Perhaps he'd lost his youthful zest, perhaps it was the smell on his breath of whatever he'd drank the night before, and which now seemed to carry over to the morning. He was getting suprisingly near to retirement age, in any case. And the thought, the ridiculous idea that he'd suddenly been on the planet for this long, scared him, and he needed something which would carry him though the years ahead. What scared him even more, though, like a lottery addict who's terrified that their number will come up on exactly the week that they stop buying the tickets, was what would happen to SETI if he stopped listening. Sometimes, looking up at the night sky as the computers at whatever faculty he was now at pounded their way through the small hours with his latest batch of star data, gazing at those taunting pinpricks with all their mystery and promise, he felt as if he was bearing the whole universe up by the effort of his mind, and that the stars themselves would go out, just as they did in that famous Clarke story, the moment he turned his back on them. It was about then that he generally thought about having another drink, just to see him through the night, just to keep up his spirits. It was no big deal. A drink was a drink. Everyone he knew did it.

So Tom finally got sufficient funds and bluff together to set up his own specialized SETI project, and then settled on France for reasons he couldn't now quite remember, except that it was a place he hadn't been to where they still spoke a language which wasn't English, and then chose the karst area of the Massif Central because it gave the sort of wide flat planes which fitted with the technology of his tripwire receivers, and was high up and well away from the radio babble of the cities. The choice was semi-symbolic—as well as the tripwires, he planned to borrow and buy-in as much useful data as he could from all possible sources, and process it there with whatever equipment he could borrow or cannibalize. Then he saw the waterhole, a tiny blue dot on the map of this otherwise desolate mountain-plateau above a small place called St. Hilaire, and that settled it. He hadn't even known that the place was a flying resort, until he'd signed all the necessary legal papers and hitched his life to it. And even that, in its way—those rainbow butterflies and beetles, those prismatic famine victims clustering around their smart bars and expensive shops, queuing with their wings whispering to take the cable lifts to the high peaks in the sunstruck south each morning—seemed appropriate. It made him think of Terr, and how her life had been, and it reminded him—as if he'd ever forgotten—of his, of their promise.

But it had never happened. There'd never been a reason to let her know.

She stood back from him and sighed, scarecrow figure in her scarecrow dress, long hair in cobwebs around her thin and witchy face.

"I'm sorry, Tom—"

"—No, it isn't—"

"—I was making presumptions."

But Tom knew who and what was to blame. Too many years of searching, too many years of drink. He sat outside his hut, frozen in his chair with his tripwires glimmering, and watched as Terr wandered off. He heard the clink of bottles as she inspected his dumpster. He heard the shuffle of rubbish as she picked her way around indoors. He should have felt ashamed, but he didn't. He was past that, just as he was past, he realized, any approximation of the act of love.

When Terr came out again into the starlight, she was carrying a bottle. It was the absinthe.

"Is this what you want?" she said, and unstoppered it. She poured a slug of the stuff out into her own empty wineglass, and raised it to her thin lips, and sipped. Even under this starlight, her face grew wrinkled, ugly. "God, it's so bitter …"

"Perhaps that's why I like it."

"You know, you could get rid of this habit, Tom. It's like you said to me—if there's something about yourself you don't like, all you need do is take a vial."

Tom shrugged, wondering whether she was going to pour some absinthe out into his glass or just stand there, waving the bottle at him. Was he being deliberately taunted? But Terr was right, of course. You took a vial, and you were clean. The addiction was gone. Everything about you was renewed, apart from the fact that you were who you were, and still driven by the same needs and contradictions which had given you the craving in the first place. So you went back to the odd drink, because you knew you were clean now, you were safe. And the odd drink became a regular habit again, and you were back where you started again, only poorer and older, and filled with an even deeper self-contempt. And worse headaches. Yes, Tom had been there.

"It's like you say, Terr. We are as we are. A few clever chemicals won't change that."

"You're going to be telling me next that you're an addictive personality."

"I wouldn't be here otherwise would I, doing this?"

She nodded and sat down again. She tipped some absinthe into his glass, and Tom stared at it, and at the faintly glowing message cards which he still hadn't read which lay beside it on the table, allowing a slight pause to elapse before he drank the absinthe, just to show her that he could wait. Then the taste of anise and wormwood, which was the name of the star, as he recalled, which had fallen from the heavens and seared the rivers and fountains in the Book of Revelation. It had all just been a matter of belief, back then.

"You still haven't told me how things have been for you, Terr."

"They've been okay. On and off …" Terr considered, her head in shade and edged with starlight. Tom told himself that the skull he could now see had always been there, down beneath Terr's skin that he had once so loved to touch and taste. Nothing was really that different. "With a few regrets."

"Did you really get into flying? That was how I always pictured you, up in the skies. Like the kids you see now down in this valley."

"Yes! I was a flyer, Tom. Not quite the way they are now—I'm sure they'd think the stuff we used then was uselessly heavy and clumsy. But it was great while it lasted. I made a lot of friends."

"Did you ever go back to your studies?"

She gave that dry chuckle again; the rustle of wind though old telephone wires. "I don't think I ever had studies, Tom. No, I got a job. Worked in public relations. Built up this company I was involved in very well for a while, sold other people's projects and ideas, covered up other people's mistakes—"

"—We could have used you for SETI."

"I thought of that, Tom—or of you, at least. But you had your own life. I didn't want to seem patronizing. And then I got sick of being slick and enthusiastic about other people's stuff, and I got involved in this project of my own. Basically, it was a gallery, a sort of art gallery, except the exhibits were people. I was …"

"You were one of them?"

"Of course I was, Tom! What do you expect? But it plays havoc with your immune system after a while. You hurt and ache and bleed. It's something for the very fit, the very young, or the very dedicated. And then I tried being normal and got married and unmarried, and then married again."

"Not to the same person?"

"Oh no. Although they made friends, funnily enough, did my two ex's. Last time I heard from one of them, they were both still keeping in touch. Probably still are. Then I got interested in religion. Religions, being me …"

"Any kids?"

"Now never quite seemed the time. I wish there had been a now, though, but on the other hand perhaps I was always too selfish."

"You were never selfish, Terr."

"Too unfocussed then."

"You weren't that either." Tom took another slug of absinthe, and topped up the glass. He could feel the bitter ease of it seeping into him. It was pleasant to sit talking like this. Sad, but pleasant. He realized he hadn't just missed Terr. These last few years up on his mountain, he'd missed most kinds of human company. "But I know what you mean. Even when I used to dream about us staying together, I could never quite manage the idea of kids …"

"How can two people be so different, and so right for each other?"

"Is that what you really think?"

"I loved you more than I loved anyone, Tom. All the time since, I often got this feeling you were watching, listening. Like that afternoon when I jumped with my wings from that tower in Aston and then got arrested. And the body art. You were like a missing guest at the weddings. I was either going for or against you in whatever I did—and sort of wondering how you'd react. And then I went to the Moon, and your ghost seemed to follow me there, too. Have you ever been off-planet?"

He shook his head. He hadn't—or at least not in the obvious physical sense, although he'd traveled with Kubrick over the Moon's craters a thousand times to the thrilling music of Ligeti.

"Thought not. It was the most expensive thing I ever did."

"What's it like?"

"That's just about it with the Moon, Tom—it's expensive. The place you stay in is like one of those cheap old Japanese hotels. Your room's a pod you can't even sit up in. Who'd ever have thought space could be so claustrophobic!"

"All these things you've done, Terr. They sound so fascinating."

"Do, don't they—saying them like I'm saying them now? But it was always like someone else's life that I seemed to be stuck in. Like wearing the wrong clothes. I was always looking for my own. And then you get older—God, you know what it's like! And there are so many choices nowadays. So many different ways of stretching things out, extending the years, but the more you stretch them, the thinner they get. I always knew that I never wanted to live to some great age. These one-and-a-half centenarians you see, they seem to be there just to prove a point. Tortoises in an endless race. Or animals in a grotty zoo. Minds in twisted rusty cages …"

"I'd never really thought—"

"—You'll just go on until the bang, won't you Tom? Until the booze finally wrecks some crucial organ or busts a capillary in your head. Or until the Venusians land over there on those funny wires in a flying saucer and take you away with them. Although you'd probably say no because they aren't quite the aliens you expected."

"What do you mean?"

"Nothing, Tom. It's just the way you are. And you've been lucky, really, to have managed to keep your dream intact, despite all the evidence. I read that article you did, years ago in that funny little paper with all the flashing adverts for body-changing. "New Light on the Drake Equation." I had to smile. You still sounded so positive. But don't you think we'd have heard from them by now, if they really were out there? Think of all the millions of stars, all these millions of years, and all those galactic civilisations you used to read about. It wouldn't be a whisper, would it, Tom, something you needed all this fiddly technology to pick up on? It would be all around us, and unavoidable. If the aliens wanted us to hear from them, it would be an almighty roar …"

The stars were just starting to fade now at the edge of the east; winking out one by one in the way that Tom had always feared. Taurus, Orion … The first hint of light as this part of the planet edged its face towards the sun was always grey up here on the karst, oddly wan and depressing. It was the color, he often felt as the night diluted and the optimism that the booze inspired drained out of him in torrents of piss and the occasional worrying hawk of bloody vomit, that his whole world would become—if he lost SETI. And the argument which Terr had so cannily absorbed, was, he knew, the most damning of all the arguments against his dream. The odd thing was, it lay outside the Drake Equation entirely, which was probably why that dumb article of his had avoided mentioning it. What Terr was saying was a version of a question that the founding father of the nuclear chain reaction Enrico Fermi had once asked in the course of a debate about the existence of extra-terrestrial intelligence nearly a century and half—and how time flew!—ago. The question was simply this: "Where are they?"

There were these things called von Neumann machines; perhaps Terr knew that as well. They'd once been a theory, and stalwarts of the old tales of the future Tom had loved reading, but now they were out working in the asteroid belt and on Jupiter's lesser moons, and down in deep mines on earth and the sea trenches and on Terr's moon and any other place where mankind wanted something but didn't want to risk its own skin by getting it. They were robots, really, but they were able to manufacture new versions of themselves—reproduce, if you wanted to make the obvious biological comparison—using the available local materials. They were smart, too. They could travel and adapt to new environments. They could do pretty much anything you wanted of them. So surely, went the argument which sometimes crept along with the depression and the morning hangover into Tom's head, any other intelligent lifeform would have come up with a similar invention? Even with the staggering distance involved in travel between the stars, all you had to do was launch some into space, wait a few million years—a mere twitch of God's eye, by any cosmological timescale—and the things would be colonizing this entire galaxy. So where were they?

The answer was as simple as Fermi's question: They aren't here. And mankind was a freak; he and his planet were a fascinating outrage against all the laws of probability. The rest of the universe was either empty, or any other dim glimmerings of life were so distant and faint as to be unreachable in all the time remaining until the whole shebang collapsed again. Better luck next time, perhaps. Or the time after that. By one calculation of the Drake Equation Tom had read, life of some kind was likely to appear somewhere in the entire universe once in every 10¹⁰ big bangs, and even that was assuming the physical laws remained unchanged. The guy hadn't bothered to put the extra spin on the figure which would involve two communicating intelligences arising at the same time and in the same corner of the same galaxy. Probably hadn't wanted to wreck his computer.

Half the sky was greying out now. Star by star by star. At least he'd soon get a proper look at Terr, and she'd get a proper look at him, although he wasn't sure that that was what either of them wanted. Perhaps there was something to be said for the grey mists of uncertainty, after all.

"I always said—didn't I, Tom?—that I'd bring you a message."

"And this is it? You saying I should give up on the one thing that means something to me?"

"Don't look at it like that, Tom. Think of it as …" A faint breeze had sprung up, the start of the wind that would soon lift the flyers as the temperature gradients hit the valley. Tom thought for a moment that they must still have a candle burning on the table between them, the way Terr seemed to flicker and sway beyond it. She was like smoke. Her hair, her face. He poured himself some more absinthe, which he decided against drinking. "The thing is, Tom, that you've got yourself into this state when you imagine that whether or not you listen in itself proves something. It doesn't, Tom. They're out there—they're not out there. Either way, it's a fact already isn't it? It's just one we don't happen to know the answer to … And wouldn't it be a pity, if we knew the answer to everything? Where would your dreams be then?"

"Science is all about finding out the truth—"

"—And this life of yours, Tom! I mean, why on earth do you have to go down to the village to pick up those messages? Can't you communicate with people from up here? It looks like you've got enough equipment in that hut to speak to the entire world if you wanted to. But I suppose that doesn't interest you."

"I find personal messages …" He gazed at the hills in the east as a questing spear of light rose over them, then down at the cards she'd brought up to him. "I find them distracting."

"I'm sorry, Tom. I don't want to distract you."

"I didn't mean …" There he went again. Terr in tears, just the way she'd been, in a memory he'd suppressed for so long, in his bed in Erdington on that night of the Mars landing when the booze first started to get the better of him. But this was different. Terr was different. She was twisting, writhing. And the wind, the dawn, was rising.

"And I always felt responsible for you in a way, Tom. It was probably just a sort of vanity, but I felt as if I'd given you some final push along a path down which you might not otherwise have taken. You were charming, Tom. You were handsome and intelligent. You could have made a fortune and had a happy life doing anything other than SETI. Is that true Tom? Does that make any sense to you?"

He didn't reply, which he knew in itself was a positive answer. The truth was always out there in any case, with or without him. What was the point in denying anything?

"And that promise I made you make, that last day when we were standing outside the law courts with all those stupid flyer friends of mine. It seemed clever, somehow. I knew how much you still loved me and I wanted to leave my mark on you, just to prove it. I'm sorry, Tom. It was another one of my stupid, stupid projects …"

"You can't hold yourself responsible for someone else's life, Terr."

"I know, Tom. It didn't even feel like I was responsible for my own."

Tom looked away from Terr, and back at his ragged hut. But for the fine-spun silver of his field of tripwires, but for the faint glow of his computers, but for the bottle-filled dumpster and the old Citroën beside it, it could have been the dwelling of a medieval hermit. He sighed and looked down the slope of his mountain. In this gathering light, the whole world looked frail as a spiderweb. And down there—he could just see it—lay his waterhole, and the flickering movement of the shy mountain ibex who gathered dawn and dusk to drink there.

"The sun's coming up, Tom. I'll have to be going soon …"

"But you haven't …" The words froze in his mouth as he looked back at Terr. Even as the light strengthened, the substance was draining from her." … can't you stay…?"

"I'm sorry, Tom. I've said all there is to be said …"

She stood up and moved, floated, towards him. Changed and not changed. Terr and not Terr. What few stars remained in the west were now shining right through her. But Tom felt no fear as she approached him. All he felt, welling up in his heart, was that childhood ache, that dark sweetness which was cola and ice cream and his mother's embrace. All he felt was a glorious, exquisite, sense of wonder.

The rim of the sun gilded the edge of those ranged peaks. Terr broke and shimmered. She was like her eyes now; a beautiful swarming nebula. But the sun was brightening, the wind was still rising. She was fading, fading. Tom stretched out a hand to touch whatever it was she had become, and found only morning coolness, the air on his flesh.

Remember, Tom.

Terr had no voice now, no substance. She was just a feeling, little more than the sad and happy memory he had carried with him through all these years into this dim and distant age. But he felt also that she was moving, turning away from him, and he smiled as he watched her in that dark blue dress, as beautiful as she had always been, walking away down the silvered turf of his mountain towards the waterhole. Terr with her blonde hair. Terr with her beautiful eyes. Terr with the mist on her flesh in that place where her jaw met her throat beneath her earlobe. She turned and gave him a smile and a wave as the sun sent a clear spine of light up from the cleft between two mountains. Terr in her dark blue dress, heading down towards that waterhole where all the shy creatures of the universe might gather at the beginning or end of the longest of days. Then she was gone.

The cards on the table before him had lost most of their glow. And they were cold and slickly damp when he turned them over. He selected the one card he didn't recognize, the one which was blue and almost plain, with a pattern on its surface like rippled water. He was sure now that it was more than just spam, junk mail. He ran his finger across the message strip to activate it, and closed his eyes, and saw a man standing before him in a fountained garden which was warm and afternoon-bright and almost Moorish; it could have been Morocco, Los Angeles, Spain. The man was good-looking, but no longer young. He had allowed the wrinkles to spread over his face, his hair to grey and recede. There was something, Tom found himself thinking, about himself about his face, or at least the self he thought he remembered once seeing in a mirror. But the man was standing with the fixedness of someone preparing for a difficult moment. His face was beyond ordinary sadness. His eyes were grave.

Tom waited patiently through the you-don't-know-me-and-I-don't-know-you part of the message, and the birds sang and the bees fumbled for pollen amid deep red and purple tropic flowers as the man gave Tom his name, and explained the one thing about their backgrounds which they had in common, which was that they had both loved Terr. They'd loved Terr, and then of course they'd lost her, because Terr was impossible to keep—it was in her nature; it was why they'd made the glorious leap of loving her in the first place. But this man was aware of Tom Kelly in a way that Tom wasn't aware of him. Not that Terr had ever said much about her past because she lived so much in the present, but he'd known that Tom was there, and in a way he'd envied him, because love for Terr was a first and only thing, glorious in its moment, then impossible to ever quite recapture in the same way. So he and Terr had eventually parted, and their marriage—which was her second, in any case—had ended as, although he'd hoped against hope, he'd always known it would. And Terr had gone on with her life, and he'd got on with his, and he'd followed her sometimes through the ether, her new friends, her new discoveries and fresh obsessions, until he heard this recent news, which was terrible, and yet for him, not quite unexpected, Terr being Terr.

There was a ridge on a peak in the Andes known as Catayatauri. It sounded like a newly discovered star to Tom, and was almost as distant and as hostile. The ridge leading up to it was incredible; in the east, it dropped nearly ten thousand sheer feet, and it took a week of hard walking and another week of hard climbing to reach it, that was, if the winds and the treacherous séracs let you get there at all. But it had acquired a near-mythic reputation amongst a certain kind of flyer, a reputation which went back to the time of the Incas, when human sacrifices were thrown from that ridge to placate Viracocha, the old man of the sky.

So picture Terr making that climb alone in the brutal cold, no longer as young or as fit as she might once have been, but still as determined. She left messages in the village which lay in Catayatauri's permanent shadow. If she didn't come back, she didn't want anyone risking their lives trying to find her. The Incas had felt Catayatauri with a deep, religious, intensity, and so had the climbers who came after, and so must Terr, alone up in those godly mountains. She climbed unaided; no wings, no muscle or lung enhancements, no crampon claws on her feet or hands, no ropes, and no oxygen. The fact that she made it there at all was incredible, clinging to that ridge at the roof of the world. From Catayatauri, from that drop, nothing else was comparable. And Terr had stood there alone, a nearly-old woman at the edge of everything. She'd bought vials at a shop in Lima. She'd emptied what little she had left in her accounts to get hold of them. These weren't like the vials they sold along the Rue de Commerce in St. Hilaire. Scarcely legal, they were the quickest acting, the most radical, the most expensive. They tore through your blood and veins by the nanosecond, they burned you up and twisted your body inside out like a storm-wrecked umbrella. And Terr had purchased three times the usual dosage.

And she probably did get there, and make the leap from the ridge on Catayatauri. It seemed like the most likely explanation, even though her body hadn't been found. Terr had thrown herself from the precipice with the vials singing in her body, her bones twisting, the wings breaking out from her like a butterfly emerging from a chrysalis, although they would have been too damp and frail to do more than be torn to shreds in the brutal torrents of air. And then, finally, finally, she would have been buffeted onto the rocks. Terr, it seemed, had chosen the most extreme of all possible ways of dying …

Was it like her, to do this, Tom wondered? Terr plummeting, twisting and writhing? Had she meant to kill herself, or just wanted to take the risk, and lived the moment, and not really cared about the next? The man in the Moorish garden was as lost and puzzled by all these questions as Tom was himself. But the thing about Terr, as they both realized, was that she had always changed moment by moment, hour by hour, year by year. The thing about Terr was that you could never really know her. Tom, he had always been steady and purposeful; long ago, he had laid down the tracks of his life. Terr was different. Terr was always different. She'd never been troubled as Tom had been most of his life by that sense of missed appointments, unfinished business, time slipping by; of a vital message which he had never quite heard. Terr had always leapt without looking back.

The man gave a smile and signed off. The Moorish garden, the dense scent of the flowers, faded. Tom Kelly was back in the morning as the shadows raced the clouds over his mountain; and he was wondering, like a character in a fairy story, just where he had been the previous night, and exactly what it was that he had witnessed. And if he could have been granted one wish—which was something that Terr, whatever she had been, hadn't even offered to him—it would still be the thing for which he had always been hoping. He was nearly seventy, after all. He was Tom Kelly; Mr. SETI. No matter what happened to you, no matter what wonders you witnessed, people his age didn't change. He was still sure of that, at least.

Things are just starting to reawaken when he emerges into the blazing Place de la Révolution, and he has to move his Citroën and park it round the corner to make room for the evening's festivities. It's the Foire aux Sorcières tonight, which a few months ago would have meant nothing to him, and still means little enough. But the French like a good festival, he knows that much now at least. They have them here in St. Hilaire regularly—in fact, almost every week, seeing as there's such a regular throughput of new flyers needing to have their francs taken from them. But this festival is special. Tom knows that, too.

Drinking sweet hot coffee at his usual table, he passes the necessary hour while the market stalls and the stage for the evening pageant assemble themselves to the attentions of robot crabs and the clang of poles and the shouts of a few largely unnecessary artisans. The town, meanwhile, stretches itself and scratches its belly and emerges from its long meals and lovers' slumbers. The girl with that Audrey Hepburn look, whom he now knows is called Jeannette, gives him a smile and goes over to say hi, bonjour. She thinks it's sweet, that a mad old mountain goat like Tom should take the long way around to learning her language. And so does Michel, her boyfriend, who is as urbane and charming as anyone can be who's got the muscles of a cartoon god and the green scaly skin of a reptile. They even help Tom carry his few boxes of stuff from the boot of his Citroën to the stall he's booked, and wish him luck, and promise to come back and buy something later on in the evening, although Tom suspects they'll be having too much fun by then to remember him.

But it turns out that business at his stall is surprisingly brisk in any case. It's been this way for a couple of weeks now, and if it continues, Tom reckons he'll have to order some new SETI tee-shirts and teatowels to replace his lost stock, although the teatowels in particular will be hard to replace after all these years, seeing as people don't seem to have any proper use for them any longer. They ask him what they're for, these big SETI handkerchiefs, and then tie them around their necks like flags. Who'd have thought it—that teatowels would be a casualty of this future he finds himself in? But bargaining, setting a price for something and then dropping it to make the sale; that's no problem for Tom. The numbers of another language come almost easily to him; he supposes his brain dimly remembers it once had an aptitude for maths.

The Foire aux Sorcières seems an odd festival for summer, but, even before the darkness has settled, the children are out, dressed as witches, ghosts, goblins, and waving lanterns which cast, through some technical trick Tom can't even guess at, a night-murk across their faces. Still, the whole occasion, with those sweet and ghastly faces, the trailing sheets with cut eye-holes, the shrieking, cackling devices, has a pleasantly old-fashioned feel about it to Tom. Even the flyers, when they emerge, have done nothing more to change themselves than put on weird costumes and make-ups, although, to Tom's mind at least, many of them had looked the part already. The scene, as the sun finally sinks behind the tenements and a semblance of cool settles over the hot and frenzied square, is incredible. Some of the people wandering the stalls have even dressed themselves up as old-fashioned aliens. He spots a bulge-headed Martian, then a cluster of those slim things with slanted eyes that were always abducting people in the Midwest, and even someone dressed as that slippery grey thing that used to explode out of people's stomachs in the films, although the guy's taken the head off and is mopping his face with one of Tom's SETI teatowels because he's so hot inside it. If you half-closed your eyes, Tom thinks, it really could be market day on the planet Zarg, or anywhere else of a million places in this universe which he suspects that humanity will eventually get around to colonizing, when it stops having so much fun here on earth. Look at Columbus, look at Cook, look at Einstein, look at NASA. Look at Terr. We are, in the depths of our hearts, a questing, dreaming race.

Small demons, imps and several ghosts cluster around him now, and ask him qu'est-ce que SETI? which Tom attempts to explain in French. They nod and listen and gaze up at him with grave faces. He's almost thinking he's starting to get somewhere, when they all dissolve into gales of laughter and scatter off though the crowds. He watches them go, smiling, those ghosts, those flapping sheets. When he refocuses his gaze, Madame Brissac has materialized before him. She is dressed as an old-fashioned witch. But she seems awkward beneath her stick-on warts and green make-up, shorn of the usual wooden counter which, even now that they're attempting to talk to each other in the same language, still separates Tom and her. Still, she politely asks the price of his SETI paperweights, and rummages in her witchy bag and purchases one from him, and then comments on the warmth and the beauty of this evening, and how pretty and amusing the children are. And Tom agrees with her in French, and offers Madame Brissac a SETI tea towel at no extra cost, which she declines. Wishing him a good evening, she turns and walks away. But Tom still feels proud of himself, and he knows that's she's proud of him too. It's an achievement for them both, that they can talk to each other now in the same language, although, being Madame Brissac, she'll never quite let it show.

The music rides over him. The crowds whoop and sing. The lanterns sway. Down the slope towards the river, the lace-draped stalls look almost cool in the soft breeze which plays down from the hills and over the tenements as Tom sweats in his SETI tee-shirt. Jean-Benoît's down there, dressed red as fallen Lucifer and surrounded by lesser demons, and looking most strange and splendid for his evening off. There's no sign, though, of the woman in the dark blue dress whom Tom glimpsed standing in the sunlight all those week ago. He knows that Terr's dead now, although the thought still comes as a cold blunt shock to him. So how could there ever be any sign of Terr?

Tom's got his days better sorted now. He's never again gotten so drunk as to lose one whole day and imagine Thursday is Wednesday. In fact, nowadays, Tom never has a drink at all. It would be nice to say that he's managed it through pure willpower. But he's old, and a creature of habit, even when the habits are the wrong ones. And this is the future, after all. So Tom's taken a vial, just as he had done several times before, and the need, the desire, the welling emptiness, faded so completely that he found himself wondering for the first few days what all the trouble and fuss had been about. But that was two months ago, and he still rarely entertains the previous stupid thoughts about how a social drink, a sip and a glass here and there, would be quite safe for someone like him. Even on a night such as this, when the air smells of wine and sweat and Pernod and coffee and Gitanes, and he can hear bottles popping and glasses clinking and liquid choruses of laughter all around the square, he doesn't feel the usual emptiness. Or barely. Or at least he's stopped kidding himself that it's something the alcohol will ever fill, and decided to get on with the rest of his life unaided.

He sometimes wonders during the long hot afternoons of his lessons with Madame Brissac whether a woman in a blue dress and grey or blonde hair really did enter the bureau de poste to inquire about an elderly American called Tom Kelly on that magical Thursday. Sometimes, he's almost on the brink of interrupting her as she forces him through the endless twists and turns of French grammar, although he knows she'd probably regard it as an unnecessary distraction. He's thought of asking Jean-Benoît, too—at least, when he's not dressed up as Lucifer—if he remembers a woman who could have been old or might have been young coming to his café, and who undertook to pass on the message cards he'd forgotten to take with him. Would they remember Terr? Would they deny that they'd ever seen her at all? More likely, Tom has decided, they'll have long forgotten such a trivial incident amid the stream of faces and incidents which populate their lives.

Tom glances up from the bright Place de la Révolution at the few faint stars which have managed to gather over the rooftops and spires of St. Hilaire. Like Terr—or the ghost of her—he suspects they'll remain a mystery that he'll have carry to his grave. But there's nothing so terrible about mysteries. It was mystery, after all, which drew him to the stars in the first place. Wonder and mystery. He smiles to himself, and waves to Jeannette and Michel as they pass through the crowds. Then Jean-Benoît , amid great cheers, flaps his crimson wings and rises over the stalls and hovers floodlit above the church spire to announce the real beginning of the night's festivities, which will involve fireworks, amazing pageants, dancing …

This Foire aux Sorcières will probably still be going on at sunrise, but Tom Kelly knows it will be too much for him. He's getting too old for this world he finds himself in. He can barely keep pace. But he permits himself another smile as he starts to pack up his stall of SETI memorabilia, the tee-shirts and paperweights, the lapel pins embossed with a tiny representation of the Drake Equation which not a single person who's bought one of the things has ever asked him to explain. He's looking forward to the midnight drive back up his mountain in his old Citroën, and the way the stars will blossom when he finally turns off the headlights and steps into the cool darkness outside his hut, with the glitter of his tripwires, the hum and glow of his machines. Who knows what messages might be up there?

He's Tom Kelly, after all.

And this might be the night.

He's still listening, waiting.
