The American government"s s.p.a.ce program remained strictly military. But the brilliant and ruthless entrepreneur Delos Harriman, spurred on by the British example, started a commercially funded s.p.a.ce program in the States, and in 1970 finally reached the Moon using conventional multistage chemical boosters. Sir Bill"s account of Harriman"s achievement is curiously muted; it"s clear he doesn"t think much of the Yankee mix of rabid capitalism and pioneer individualism. And of course the British, using their atomic technology, had already reached Mars in 1968 - here, drawing upon extensive interviews with the protagonists, Sir Bill deftly improves upon Patrick Moore"s cla.s.sic account, in Mission to Mars, of how the first expedition was stranded because the motor of their craft was damaged on landing, and of how they survived for a year before a second expedition rescued them.

With the Moon and Mars secured by the British government and American free enterprise, the Russians turned their attention to the inner solar system. Only recently, after the fall of the Communist state, has the tragic fate of the first manned expedition to Venus been revealed. No one who has heard the recordings will forget the screams of the two unlucky cosmonauts as their descent capsule was cooked and crushed in Venus"s infernal atmosphere. There"s no derring-do here: only horror. What had been intended as a coup de theatre to trump the British expedition to Mars became a tragedy that was hastily covered over, and Sir Bill has cannily exploited the recent openness of the new Russian government to secure at first hand accounts of the Venus disaster. The first Russian landing on Mercury, four years later, in 1972, was of course more successful, establishing solar-powered robot mining facilities and a rail gun which within a year began to launch back to Earth packages of refined precious metals, immensely enriching the Russian economy, and starting in earnest the race to commercially exploit the solar system.

By this time the British had established a permanent colony on the Moon, and a dozen expeditions were exploring her surface in powerful tractors. Early s.p.a.ce suits, which had borrowed their design from deep sea diving outfits, heavily armoured and with pincers instead of gloves, had given way to more comfortable suits based on the indestructible cloth invented by Sidney Stratton, with integral life support backpacks instead of heavy metal air cylinders. There was also a semi-permanent scientific station on Mars. After the disappointment that the fabulous ca.n.a.ls of Lowell had been no more than optical illusions and wishful thinking, the British Geological Society was busily exploring vast canyons, craters and volcanoes, and drilling deep for signs of life in the Martian crust. In 1977, to celebrate the Queen"s Jubilee, a British climbing expedition planted the Union Jack on top of Mount Elizabeth, the largest volcano in the solar system.

All of this was no longer under the control of the military, but was funded by a mixture of public subscription, commercial money (especially from the BBC"s Relay Chain satellite network), and money earned by transporting material for American and Russian projects - just as in the old British Empire, the new colonies were largely self-funding. Meanwhile, British atomic-powered s.p.a.ce ships were carrying out the first surveys of the moons of Jupiter and Saturn. Life was discovered in Europa"s salty sub-ice ocean in 1982; the first expedition landed, if that"s the right word for a descent to a surface covered in liquid ethane, on t.i.tan in 1988.

While British expeditions are bringing back treasures to the Science Museum, and the British government has built an extensive s.p.a.ceport in Ceylon to service almost daily flights to Earth orbit and the Moon, the official US s.p.a.ce program is still recovering from the political and economic fallout of the Second American Revolution. The Lunar colony founded by Harriman"s company had been taken over by the feds in 1977, and used as a dumping ground for dissidents after Nixon was elected to his third term as president. In 1979, a revolt by the imprisoned dissidents led to the foundation of the Lunar Republic and the fall of the Nixon government after a brief bombardment of the American mainland by rocks launched by the Lunar rail gun. Sir Bill"s account of the revolt, the former Lunar prison"s declaration of independence and the brief war quite rightly highlights the way mainstream history (heavily influenced by Heinlein"s colourful but disapproving popular account in The Moon is a Harsh Mistress, whose claims that libertarian heroes were suppressed by evil socialist radicals and drug-crazed hippies would be pitiful if they weren"t, thanks to the movie version, still so widely held) has unfairly dismissed the discreet but vital help given by the British Lunar colonists to the former prisoners. For as this writer can affirm from personal experience, the phlegmatic Brit scientists were surprisingly sympathetic to us hepcat hippie rebels.

After the revolution, some of the rebels, including William Burroughs and Jack Kerouac, chose to return to Earth, but this wasn"t, as Sir Bill claims, a split in our ranks, merely a natural shakedown amongst a bunch of highly creative and mostly anarchic individuals. Many others, including Ken Kesey, Allen Ginsberg, Neil Ca.s.sady, Tom Hayden and Noam Chomsky, stayed on to found a new republic that attempted to marry the artistic impulses of many of its members with the technology required for survival. Very soon, we in the New Lunar Utope became expert at building habitats from scratch, and furnishing them with self-sufficient closed ecosystems; something we developed by ourselves by the way, despite Sir Bill"s crude hints that we were dependent on British expertise. It just wasn"t so, Bill: we had to learn to develop efficient closed-loop systems quickly or perish, and as this veteran of Ken Kesey"s magic bus tour of the Martian highlands can affirm from personal experience, it was all down to good old Yankee ingenuity.

After the fall of Nixon and the election of Ronald Reagan, detente with the Russians swiftly followed, and the end of the cold war has led to a welcome diversion of funding from the US military s.p.a.ce program to the construction of habitats and factories and solar power farms in Earth orbit and at the L5 point between Earth and the Moon. It"s a healthy sign, surely, that the habitats are not the transplanted whitebread suburbias of NASA"s drawing boards, but are designed by the New Lunar Utope as diverse multicultural centres for any artistic and scientific community that can afford the one-way ticket out of Earth"s gravity well.

Meanwhile, the Russians have consolidated their exploitation of the vast resources of Mercury and have begun to mine many near-Earth asteroids. After the fall of Communism, Mercury declared itself an independent republic, and dozens of mining communities scattered through the asteroid belt have declared their autonomy too. Sir Bill"s explication of the political links between the former Soviet mining stations and the Free Lunar Utope is enjoyably disapproving. He"s forced to admit that the British hegemony is now strongly compromised by plans to extend the alliance to the outer reaches of the solar system by slingshotting seed colonies past Venus towards the newly discovered planetoids of the Kuiper Belt, and his speculation that the Free Lunar Utope and the Autonomous s.p.a.ce Republics have transformed the comet fragment Neo-8 into a multi-generation starship aimed at Tau Ceti reeks of panicky paranoia.

It"s understandable that the Brits are nervous. It turns out that the bustling solar system hasn"t become the new British Empire after all, and it"s natural that they don"t want their tremendous investment in the first robot interstellar probes -due to be launched within the next two years towards the eight extra-solar systems with Earth-like planets discovered by the Newton s.p.a.ce telescope on the far side of the Moon - to be upstaged. But hey, whatever happens, and here I"m in complete agreement with Sir Bill: we can only look back fondly and admiringly on the writings of the first prophets of the s.p.a.ce age, and marvel at how timid their once outrageously optimistic predictions now seem. Let a thousand flowers bloom!

The Imitation Game.

Rudy Rucker.

It was a rainy Sunday night, June 6, 1954. Alan Turing was walking down the liquidly lamp-lit street to the Manchester train station, wearing a long raincoat with a furled umbrella concealed beneath. His Greek paramour Zeno was due on the 9pm coach, having taken a ferry from Calais. And, no, the name had no philosophical import, it was simply the boy"s name. If all went well, Zeno and Alan would be spending the night together in the sepulchral Manchester Midland travelers" hotel-Alan"s own home nearby was watched. He"d booked the hotel room under a pseudonym.

Barring any intrusions from the morals squad, Alan and Zeno would set off bright and early tomorrow for a lovely week of tramping across the hills of the Lake Country, free as rabbits, sleeping in serendipitous inns. Alan sent up a fervent prayer, if not to G.o.d, then to the deterministic universe"s initial boundary condition.

"Let it be so."

Surely the cosmos bore no distinct animus towards h.o.m.os.e.xuals, and the world might yet grant some peace to the tormented, fretful gnat labeled Alan Turing. But it was by no means a given that the a.s.signation with Zeno would click. Last spring, the suspicious authorities had deported Alan"s Norwegian flame Kjell straight back to Bergen before Alan even saw him.

It was as if Alan"s persecutors supposed him likely to be teaching his men top-secret code-breaking algorithms, rather than sensually savoring his rare hours of private joy. Although, yes, Alan did relish playing the tutor, and it was in fact conceivable that he might feel the urge to discuss those topics upon which he"d worked during the war years. After all, it was no one but he, Alan Turing, who"d been the brains of the British cryptography team at Bletchley Park, cracking the n.a.z.i Enigma code and shortening the War by several years-little thanks that he"d ever gotten for that.

The churning of a human mind is unpredictable, as is the anatomy of the human heart. Alan"s work on universal machines and computational morphogenesis had convinced him that the world is both deterministic and overflowing with endless surprise. His proof of the unsolvability of the Halting Problem had established, at least to Alan"s satisfaction, that there could never be any shortcuts for predicting the figures of Nature"s stately dance.

Few but Alan had as yet grasped the new order. The prating philosophers still supposed, for instance, that there must be some element of randomness at play in order that each human face be slightly different. Far from it. The differences were simply the computation-amplified results of disparities among the embryos and their wombs-with these disparities stemming in turn from the cosmic computation"s orderly exfoliation of the universe"s initial conditions.

Of late Alan had been testing his ideas with experiments involving the ma.s.sed cellular computations by which a living organism transforms egg to embryo to adult. Input acorn; output oak. He"d already published his results involving the dappling of a brindle cow, but his latest experiments were so close to magic that he was holding them secret, wanting to refine the work in the alchemical privacy of his starkly under-furnished home. Should all go well, a n.o.bel prize might grace the burgeoning field of computational morphogenesis. This time Alan didn"t want a droning gas-bag like Alonzo Church to steal his thunder-as had happened with the Hilbert Entscheidungs problem.

Alan glanced at his watch. Only three minutes till the coach arrived. His heart was pounding. Soon he"d be committing lewd and lascivious acts (luscious phrase) with a man in England. To avoid a stint in jail, he"d sworn to abjure this practice-but he"d found wiggle room for his conscience. Given that Zeno was a visiting Greek national, he wasn"t, strictly speaking, a "man in England", a.s.suming that "in" was construed to mean "who is a member citizen of". Chop the logic and let the tree of the Knowledge of Good and Evil fall, soundless in the moldering woods.

It had been nearly a year since Alan had enjoyed manly love-last summer on the island of Corfu with none other than Zeno, who"d taken Alan for a memorable row in his dory. Alan had just been coming off his court-ordered estrogen treatments, and thanks to the lingering effects of the libido-reducing hormones, the s.e.x had been less intense than one might wish. This coming week would be different. Alan felt randy as a hat rack; his whole being was on the surface of his skin.

Approaching the train station, he glanced back over his shoulder-reluctantly playing the socially a.s.signed role of furtive perv-and sure enough, a weedy whey-faced fellow was mooching along half a block behind, a man with a little round mouth like a lamprey eel"s. Officer Harold Jenkins. Devil take the beastly prig!

Alan twitched his eyes forward again, pretending not to have seen the detective. What with the growing trans-Atlantic hysteria over h.o.m.os.e.xuals and atomic secrets, the security minders grew ever more officious. In these darkening times, Alan sometimes mused that the United States had been colonized by the lowest dregs of British society: s.e.xually obsessed zealots, degenerate criminals, and murderous slave masters.

On the elevated tracks, Zeno"s train was pulling in. What to do? Surely Detective Jenkins didn"t realize that Alan was meeting this particular train. Alan"s incoming mail was vetted by the censors-he estimated that by now Her Majesty was employing the equivalent of two point seven workers full time to torment that disgraced boffin, Professor A.M. Turing. But-score one for Prof Turing-his written communications with Zeno had been encrypted via a sheaf of one-time pads he"d left in Corfu with his golden-eyed Greek G.o.d, bringing a matching sheaf home. Alan had made the pads from clipped-out sections of identical newspapers; he"d also built Zeno a cardboard cipher wheel to simplify the look-ups.

No, no, in all likelihood, Jenkins was in this louche district on a routine patrol, although now, having spotted Turing, he would of course dog his steps. The arches beneath the elevated tracks were the precise spot where, two years ago, Alan had connected with a sweet-faced boy whose dishonesty had led to Alan"s conviction for acts of gross indecency. Alan"s arrest had been to some extent his own doing; he"d been foolish enough to call the police when one of the boy"s friends burglarized his house. "Silly a.s.s," Alan"s big brother had said. Remembering the phrase made Alan wince and snicker. A silly a.s.s in a dunce"s cap, with donkey ears. A suffering human being nonetheless.

The train screeched to a stop, puffing out steam. The doors of the carriages slammed open. Alan would have loved to sashay up there like Snow White on the palace steps. But how to shed Jenkins?

Not to worry; he"d prepared a plan. He darted into the men"s public lavatory, inwardly chuckling at the vile, voyeuristic thrill that disk-mouthed Jenkins must feel to see his quarry going to earth. The echoing stony chamber was redolent with the rich scent of putrefying urine, the airborne biochemical signature of an immortal colony of microorganisms indigenous to the standing waters of the train station p.i.s.soir. It put Alan in mind of his latest Petri-dish experiments at home. He"d learned to grow stripes, spots and spirals in the flat mediums, and then he"d moved into the third dimension. He"d grown tentacles, hairs, and, just yesterday, a congelation of tissue very like a human ear.

Like a thieves" treasure cave, the wonderful bathroom ran straight through to the other side of the elevated track-with an exit on the far side. Striding through the room"s length, Alan drew out his umbrella, folded his mackintosh into a small bundle tucked beneath one arm, and hiked up the over-long pants of his dark suit to display the prominent red tartan spats that he"d worn, the spats a joking gift from a Cambridge friend. Exiting the jakes on the other side of the tracks, Alan opened his high-domed umbrella and pulled it low over his head. With the spats and dark suit replacing the beige mac and ground-dragging cuffs, he looked quite the different man from before.

Not risking a backward glance, he clattered up the stairs to the platform. And there was Zeno, his handsome, bearded face alight. Zeno was tall for a Greek, with much the same build as Alan"s. As planned, Alan paused briefly by Zeno as if asking a question, privily pa.s.sing him a little map and a key to their room at the Midland Hotel. And then Alan was off down the street, singing in the rain, leading the way.

Alan didn"t notice Detective Jenkins following him in an un-marked car. Once Jenkins had determined where Alan and Zeno were bound, he put in a call to the security office at MI5. The matter was out of his hands now.

The s.e.x was even more enjoyable than Alan had hoped. He and Zeno slept till mid-morning, Zeno"s leg heavy across his, the two of them spooned together in one of the room"s twin beds. Alan awoke to a knocking on the door, followed by a rattling of keys.

He sprang across the carpet and leaned against the door. "We"re still asleep," he said, striving for an authoritative tone.

"The dining room"s about to close," whined a woman"s voice. "Might I bring the gentlemen their breakfast in the room?"

"Indeed," said Alan through the door. "A British breakfast for two. We have a train to catch rather soon." Earlier this week, he"d had his housekeeper send his bag ahead to c.u.mbria in the Lake District.

"Very good, sir. Full breakfast for two."

"Wash," said Zeno, sticking his head out of the bathroom. At the sound of the maid, he"d darted right in there and started the tub. He looked happy. "Hot water."

Alan joined Zeno in the bath for a minute, and the dear boy brought him right off. But then Alan grew anxious about the return of the maid. He donned his clothes and rucked up the second bed so it would look slept in. Now Zeno emerged from his bath, utterly lovely in his nudity. Anxious Alan shooed him into his clothes. Fin-ally the maid appeared with the platters of food, really quite a nice-looking breakfast, with kippers, sausages, fried eggs, toast, honey, marmalade, cream and a lovely great pot of tea, steaming hot.

Seeing the maid face to face, Alan realized they knew each other; she was the cousin of his housekeeper. Although the bent little woman feigned not to recognize him, he could see in her eyes that she knew exactly what he and Zeno were doing here. And there was a sense that she knew something more. She gave him a particularly odd look when she poured out the two mugs of tea. Wanting to be shot of her, Alan handed her a coin and she withdrew.

"Milk tea," said Zeno, tipping half his mug back into the pot and topping it up with cream. He raised the mug as if in a toast, then slurped most of it down. Alan"s tea was still too hot for his lips, so he simply waved his mug and smiled.

It seemed that even with the cream, Zeno"s tea was very hot indeed. Setting his mug down with a clatter, he began fanning his hands at his mouth, theatrically gasping for breath. Alan took it for a joke, and let out one of his grating laughs. But this was no farce.

Zeno squeaked and clutched at his throat; beads of sweat covered his face; foam coated his lips. He dropped to the floor in a heap, spasmed his limbs like a starfish, and beat a tattoo on the floor.

Hardly knowing what to think, Alan knelt over his inert friend, ma.s.saging his chest. The man had stopped breathing; he had no pulse. Alan made as if to press his mouth to Zeno"s, hoping to resuscitate him. But then he smelled bitter almonds-the cla.s.sic sign of cyanide poisoning.

Recoiling as abruptly as a piece of spring-loaded machinery, Alan ran into the bathroom and rinsed out his mouth. Her Majesty"s spy-masters had gone mad; they"d meant to murder them both. In the Queen"s eyes, Alan was an even greater risk than a rogue atomic scientist. Alan"s cryptographic work on breaking the Enigma code was a secret-the very existence of his work was unknown to the public at large.

His only hope was to slip out of the country and take on a new life. But how? He thought distractedly of the ear-shaped form he"d grown in the Petri dish at home. Why not a new face?

Alan leaned over Zeno, rubbing his poor, dear chest. The man was very dead. Alan went and listened by the room"s door. Were MI5 agents lurking without, showing their teeth like hideous omnivorous ghouls? But he heard not a sound. The likeliest possibility was that some low-ranking operative had paid the maid to let him dose the tea-and had then gotten well out of the way. Perhaps Alan had a little time.

He imagined setting his internal computational system to double speed. Stepping lively, he exchanged clothes with Zeno-a bit tricky as the other man"s body was so limp. Better than rigor mortis, at any rate.

Finding a pair of scissors in Zeno"s travel kit, Alan trimmed off the pathetic, n.o.ble beard, sticking the whiskers to his own chin with smears of honey. A crude initial imitation, a first-order effect.

Alan packed Zeno"s bag and made an effort to lift the corpse to his feet. Good lord but this was hard. Alan thought to tie a necktie to the suitcase, run the tie over his shoulder and knot it around Zeno"s right arm. If Alan held the suitcase in his left hand, it made a useful counterweight.

It was a good thing that, having survived the estrogen treatments, Alan had begun training again. He was very nearly as fit as in his early thirties. Suitcase in place, right arm tightly wrapped around Zeno"s midriff and grasping the man"s belt, Alan waltzed his friend down the hotel"s back stairs, emerging into a car park where, thank you Great Algorithmist, a cabbie was having a smoke.

"My friend Turing is sick," said Alan, mustering an imitation of a Greek accent. "I want take him home."

"Blind p.i.s.sed of a Monday morn," cackled the cabbie, jumping to his own conclusions. "That"s the high life for fair. And red spats! What"s our toff "s address?"

With a supreme effort, Alan swung Zeno into the cab"s rear seat and sat next to him. Alan reached into the body"s coat and pretended to read off his home address. n.o.body seemed to be tailing the cab. The spooks were lying low, lest blame for the murder fall upon them.

As soon as the cab drew up to Alan"s house, he overpaid the driver and dragged Zeno to his feet, waving off all offers of a.s.sistance. He didn"t want the cabbie to get a close look at the crude honey-sticky beard on his chin. And then he was in his house, which was blessedly empty, Monday being the housekeeper"s day off. Moving from window to window, Alan drew the curtains.

He dressed Zeno in Turing pajamas, laid him out in the professor-ial bed, and vigorously washed the corpse"s face, not forgetting to wash his own hands afterwards. Seeking out an apple from the kitchen, he took two bites, then dipped the rest of the apple into a solution of pota.s.sium cyanide that he happened to have about the place in a jam jar. He"d always loved the scene in Snow White and the Seven Dwarfs when the Wicked Witch lowers an apple into a cauldron of poison. Dip the apple in the brew, let the sleeping death seep through!

Alan set the poison apple down beside Zeno. A Snow White suicide. Now to perfect the imitation game.

He labored all afternoon. He found a pair of cookie sheets in the kitchen-the housekeeper often did baking for him. He poured a quarter-inch of his specially treated gelatin solution onto each sheet-as it happened, the gelatin was from the bones of a pig. Man"s best friend. He set the oven on its lowest heat, and slid in the cookie sheets, leaving the oven door wide open so he could watch. Slowly the medium jelled. Alan"s customized jelly contained a sagacious mixture of activator and inhibitor compounds; it was tailored to promote just the right kind of embryological reaction-diffusion computation.

Carefully wielding a scalpel, Alan cut a tiny fleck of skin from the tip of Zeno"s cold nose. He set the fleck into the middle of the upper cookie sheet, and then looked in the mirror, preparing to repeat the process on himself. Oh blast, he still had honey and hair on his chin. Silly a.s.s. Carefully he swabbed off the mess with toilet paper, flushing the evidence down the commode. And then he took the scalpel to his own nose.

After he set his fleck of tissue into place on the lower pan, his tiny cut would keep on bleeding, and he had to spend nearly half an hour staunching the flow, greatly worried that he might scatter drops of blood around. Mentally he was running double-strength error-checking routines to keep himself from mucking things up. It was so very hard to be tidy.

When his housekeeper arrived tomorrow morning, Alan"s digs should look chaste, sarcophagal, Egyptian. The imitation Turing corpse would be a mournful memento mori of a solitary life gone wrong, and the puzzled poisoners would hesitate to intervene. The man who knew too much would be dead; that was primary desideratum. After a perfunctory inquest, the Turing replica would be cremated, bringing the persecution to a halt. And Alan"s mother might forever believe that her son"s death was an accident. For years she"d been chiding him over his messy f.e.c.klessness with the chemicals in his home lab.

Outside a car drove past very slowly. The brutes were wondering what was going on. Yet they hesitated to burst in, lest the neighbors learn of their perfidy. With shaking hands, Alan poured himself a gla.s.s of sherry. Steady, old man. See this through.

He pulled up a kitchen chair and sat down to stare through the open oven door. Like puffing pastry, the flecks of skin were rising up from the cookie sheets, with disks of cellular growth radiating out as the tissues grew. Slowly the noses hove into view, and then the lips, the eye holes, the forehead, the chins. As the afternoon light waned, Alan saw the faces age, Zeno in the top pan, Alan on the bottom. They began as innocent babes, became pert boys, spotty youths, and finally grown men.

Ah, the pathos of biology"s irreversible computations, thought Alan, forcing a wry smile. But the orotund verbiage of academe did little to block the pain. Dear Zeno was dead. Alan"s life as he"d known it was at an end. He wept.

It was dark outside now. Alan drew the pans from the oven, shuddering at the enormity of what he"d wrought. The uncanny empty-eyed faces had an expectant air; they were like holiday pie crusts, waiting for steak and kidney, for mincemeat and plums.

Bristles had pushed out of the two flaccid chins, forming little beards. Time to slow down the computation. One didn"t want the wrinkles of extreme old age. Alan doused the living faces with inhibitor solution, damping their cellular computations to a normal rate.

He carried the bearded Turing face into his bedroom and pressed it onto the corpse. The tissues took hold, sinking in a bit, which was good. Using his fingers, Alan smoothed the joins at the edges of the eyes and lips. As the living face absorbed cyanide from the dead man"s tissues, its color began to fade. A few minutes later, the face was waxen and dead. The illusion was nearly complete.

Alan momentarily lost his composure and gagged; he ran to the toilet and vomited, though little came up. He"d neglected to eat anything today other than those two bites of apple. Finally his stomach-spasms stopped. In full error-correction mode, he remembered to wash his hands several times before wiping his face. And then he drank a quart of water from the tap.

He took his razor and shaved the still-bearded dead Turing face in his bed. The barbering went faster than when he"d shaved Zeno in the hotel. It was better to stand so that he saw the face upside down. Was barbering a good career? Surely he"d never work as a scientist again. Given any fresh input, the halted Turing persecution would resume.

Alan cleaned up once more and drifted back into the kitchen. Time to skulk out through the dark garden with Zeno"s pa.s.sport, bicycle through the familiar woods to a station down the line, and catch a train. Probably the secret police wouldn"t be much interested in pursuing Zeno. They"d be glad Zeno had posed their murder as a suicide, and the less questions asked the better.

But to be safe, Turing would flee along an unexpected route. He"d take the train to Plymouth, the ferry from there to Santander on the north coast of Spain, a train south through Spain to the Mediterranean port of Tarifa, and another ferry from Tarifa to Tangiers.

Tangiers was an open city, an international zone. He could buy a fresh pa.s.sport there. He"d be free to live as he liked-in a small way. Perhaps he"d master the violin. And read the Iliad in Greek. Alan glanced down at the flaccid Zeno face, imagining himself as a Greek musician.

If you were me, from A to Z, if I were you, from Z to A...

Alan caught himself. His mind was spinning in loops, avoiding what had to be done next. It was time.

He scrubbed his features raw and donned his new face.

Weinachtsabend.

Keith Roberts.

The big car moved slowly, nosing its way along narrowing lanes. Here, beyond the little market town of Wilton, the snow lay thicker. Trees and bushes loomed in the headlights, coated with driven white. The tail of the Mercedes wagged slightly, steadied. Mainwaring heard the chauffeur swear under his breath. The link had been left alive.

Dials let into the seatback recorded the vehicle"s mechanical wellbeing; oil pressure, temperature, revs, k.p.h. Lights from the repeater glowed softly on his companion"s face. She moved, restlessly; he saw the swing of yellow hair. He turned slightly. She was wearing a neat, brief kilt, heavy boots, Her legs were excellent.

He clicked the dial lights off. He said, "Not much farther."

He wondered if she was aware of the open link. He said, "First time down?"

She nodded in the dark. She said, "I was a bit overwhelmed."

Wilton Great House sprawled across a hilltop five miles or more beyond the town. The car drove for some distance beside the wall that fringed the estate. The perimeter defences had been strengthened since Mainwaring"s last visit. Watch-towers reared at intervals; the wall itself had been topped by multiple strands of wire.

The lodge gates were commanded by two new stone pillboxes. The Merc edged between them, stopped. On the road from London, the snow had eased; now big flakes drifted again, lit by the headlights. Somewhere, orders were barked.

A man stepped forward, tapped at the window. Mainwaring b.u.t.toned it open. He saw a GFP armband, a hip holster with the flap tucked back. He said, "Good evening, Captain."

"Guten Abend, mein Herr. Ihre Ausweis Karte?"

Cold air gusted against Mainwaring"s cheek. He pa.s.sed across his ident.i.ty card and security clearance. He said, "Richard Mainwaring. Die rechte Hand zu dem Gesanten. Fraulein Hunter, von meiner Abteilung."

A torch flashed over the papers, dazzled into his eyes, moved to examine the girl. She sat stiffly, staring ahead. Beyond the Security officer Mainwaring made out two steel-helmeted troopers, automatics slung. In front of him, the wipers clicked steadily.

The GFP man stepped back. He said, "In einer Woche, Ihre Ausweis Karte ist ausgelaufen. Erneuen Sie Ihre Karte."

Mainwaring said, "Vielen Dank, Herr Hauptmann. Frohe Weihnacht."

The man saluted stiffly, unclipped a walkie-talkie from his belt. A pause, and the gates swung back. The Merc creamed through. Mainwaring said, "b.a.s.t.a.r.d...."

She said, "Is it always like this ?"

He said, "They"re tightening up all round."

She pulled her coat round her shoulders. She said, "Frankly, I find it a bit scary."

He said, "Just the Minister taking care of his guests."

Wilton stood in open downland set with great trees. Hans negotiated a bend, carefully, drove beneath half-seen branches. The wind moaned, zipping round a quarterlight. It was as if the car b.u.t.ted into a black tunnel, full of swirling pale flakes. He thought he saw her shiver. He said, "Soon be there."

The headlamps lit a rolling expanse of snow. Posts, buried nearly to their tops, marked the drive. Another bend, and the house showed ahead. The car lights swept across a facade of mullioned windows, crenellated towers. Hard for the uninitiated to guess, staring at the skilfully weathered stone, that the sh.e.l.l of the place was of reinforced concrete. The car swung right with a crunching of unseen gravel, and stopped. The ignition repeater glowed on the seatback.

Mainwaring said, "Thank you, Hans. Nice drive."
