With a galvanic leap, Hardman flung himself at Kerans, his big frame blocking off half the room, feinted just before they collided and swerved past, before Kerans could regain his balance had jumped out onto the balcony and climbed over the rail.

"Hardman!" As one of the men on the roof shouted the alarm Kerans reached the balcony. Hardman swung himself like an acrobat down the drain-pipe to the parapet below. Riggs and Macready dived into the room. Holding on to his hat, Riggs pivoted out over the rail, swore as Hardman disappeared into the apartment.

"Good man, Kerans, you nearly held him!" Together they ran back into the corridor and raced down the stairway, saw Hardman swinging around the banisters four floors below, hurling himself from one landing to the next in a single stride.

When they reached the lowest floor they were thirty seconds behind Hardman, and a medley of excited shouts were coming from the roof. But Riggs paused stock-still on the balcony.

"Good G.o.d, he's trying to drag his raft back into the water!"

Thirty yards away, Hardman was dragging the catamaran across the caking ma.s.s of silt, the tow-rope over his shoulders, jerking its bows into the air with demoniac energy.

Riggs b.u.t.toned the flap of his bolster, sadly shaking his head. There was a full fifty yards to the water's edge, and Hardman was sinking up to his knees in the damper silt, oblivious of the men on the roof looking down at him. Finally he tossed away the tow-rope and seized the bed-frame in both hands, began to wrench it along in slow painful jerks, the denim jacket split down his back.

Riggs stepped up onto the balcony, gesturing to Wilson and Caldwell to come down. "Poor devil, he looks all in. Doctor, you stay close, you may be able to pacify him."

Carefully they dosed in on Hardman. The five men, Riggs, Macready, the two soldiers and Kerans, advanced down the sloping crust, shielding their eyes from the intense sunlight. Like a wounded water-buffalo, Hardman continued to wrestle in the mud ten yards in front of them. Kerans motioned to the others to stay still and then walked forwards with Wilson, a blond-haired youth who had once been Hardman's orderly. Wondering what to say to Hardman, he cleared the knots of phlegm from his throat.

On the roof behind them there was a sudden staccato roar of exhaust, splitting the silence of the tableau. A few steps behind Wilson, Kerans hesitated, saw Riggs look up in annoyance at the helicopter. a.s.suming that their mission was now over, Daley had started his engine, and the blades were swinging slowly through the air.

Roused from his attempt to reach the water, Hardman looked around at the group encircling him, released the catamaran and crouched down behind it. Wilson began to wade forward precariously through the soft silt along the water's edge, the carbine held across his chest. As he sank up to his waist he shouted at Kerans, his voice lost in the mounting roar of the engine, exhaust spitting in sharp cracks over their heads. Suddenly Wilson swayed, and before Kerans could steady him Hardman leaned across the catamaran, the big Colt.45 in his hand, and fired at them. The flame from the barrel stabbed through the dazzling air, and with a short cry Wilson fell across the carbine, then rolled back clutching a bloodied elbow, his forage cap cuffed off his head by the discharge wave of the explosion.

As the other men began to retreat up the slope Hardman holstered the revolver in his belt, turned and ran off along the water's edge to the buildings that merged into the jungle a hundred yards away.

Pursued by the ascending roar of the helicopter, they raced after Hardman, Riggs and Kerans helping the injured Wilson, stumbling in and out of the pot-holes left by the men ahead. At the edge of the silt flat the jungle rose in a high green cliff, tier upon tier of fern trees and giant club moss flowering from the terraces. Without hesitating, Hardman plunged into a narrow interval between two ancient cobbled walls, and disappeared down the alley-way, Macready and Caldwell twenty yards behind him.

"Keep after him, Sergeant!" Riggs bellowed when Macready paused to wait for the Colonel. "We've nearly got him, he's beginning to tire." To Kerans he confided: "G.o.d, what a shambles!" He pointed hopelessly at the huge figure of Hardman pounding away in long strides. "What's driving the man on? I've a d.a.m.n good mind to let him go and get on with it."

Wilson had recovered sufficiently to walk unaided, and Kerans left him and broke into a run. "He'll be all right, Colonel; I'll try to talk to Hardman, there's a chance I may be able to hold him."

From the alley-way they emerged into a small square, where a group of sedate 19th century munic.i.p.al buildings looked down on an ornate fountain. Wild orchids and magnolia entwined themselves around the grey ionic columns of the old courthouse, a miniature sham-Parthenon with a heavy sculptured portico, but otherwise the square had survived intact the a.s.saults of the previous fifty years, its original floor still well above the surrounding water level. Next to the courthouse with the faceless clock tower, was a second colonnaded building, a library or museum, its white pillars gleaming in the sunlight like a row of huge bleached bones.

Nearing noon, the sun filled this antique forum with a harsh burning light, and Hardman stopped and looked back uncertainly at the men following him, then stumbled up the steps into the courthouse. Signaling to Kerans and Caldwell, Macready backed away among the statues in the square and took up his position behind the bowl of the fountain.

"Doctor, it's too dangerous now! He may not recognise you. We'll wait until the heat lifts, he can't move from there. Doctor-"

Kerans ignored him. He advanced slowly across the cracked flagstones, both forearms up over his eyes, and placed one foot insecurely on the first step. Somewhere among the shadows he could hear Hardman's exhausted breathing, pumping the scalding air into his lungs.

Shaking the square with its noise, the helicopter soared slowly overhead, and Riggs and Wilson hurried up the steps into the museum entrance, watching as the tail rotor turned the machine in a diminishing spiral. Together the noise and the heat drummed at Kerans' brain, bludgeoning him like a thousand clubs, clouds of dust billowing around him. Abruptly the helicopter began to lose lift, with an agonised acceleration of its engine slid out of the air into the square, then picked up just before it touched the ground pucking away, Kerans sheltered with Macready behind the fountain, while the aircraft jerked about over their heads. As it revolved, the tail rotor lashed into the portico of the courthouse, in an explosion of splintered marble the helicopter porpoised and plunged heavily onto the cobbles, the shattered tail propeller rotating eccentrically. Cutting his engine, Daley sat back at his controls, half stunned by the impact with the ground and trying helplessly to remove his harness.

Frustrated at this second attempt to catch Hardman, they crouched in the shadows below the portico of the museum, waiting for the noon high to subside. As if illuminated by immense searchlights, a vast white glare lit the grey stone of the buildings around the square, like an over-exposed photograph, reminding Kerans of the chalk-white colonnades of an Egyptian necropolis. As the sun mounted to its zenith the reflected light began to glimmer upwards from the paving stones. Periodically, while he tended Wilson and settled him with a few grains of morphine, Kerans could see the other men as they kept up their watch for Hardman, fanning themselves slowly with their forage caps.

Ten minutes later, shortly after noon, he looked up at the square. Completely obscured by the light and glare, the buildings on the other side of the fountain were no longer continuously visible, looming in and out of the air like the architecture of a spectral city. In the centre of the square, by the edge of the fountain, a tall solitary figure was standing, the pulsing thermal gradients every few seconds inverting the normal perspectives and magnifying him fleetingly. Hardman's sun-burnt face and black beard were now chalkwhite, his mud-stained clothes glinting in the blinding sunlight like sheets of gold.

Kerans pulled himself to his knees, waiting for Macready to leap forward at him, but the Sergeant, with Riggs beside him, was buddied against a pillar, his eyes staring blankly at the floor in front of them, as if asleep or entranced.

Stepping away from the fountain, Hardman moved slowly across the square, in and out of the shifting curtains of light. He pa.s.sed within twenty feet of Kerans, who knelt hidden behind the column. One hand on Wilson's shoulder, quieting the man's low grumbling. Skirting the helicopter, Hardman reached the far end of the courthouse and there left the square, walking steadily up a narrow incline towards the silt banks which stretched along the sh.o.r.e a hundred yards away.

Acknowledging his escape, the intensity of the sunlight diminished fractionally.

"Colonel Riggs!"

Macready plunged down the steps, shielding his eyes from the glare, and pointed off across the silt flat with his Thompson. Riggs followed him, hatless, his thin shoulders pinched together, tired and dispirited.

He put a restraining hand on Macready's elbow. "Let him go, Sergeant. We'll never catch him now. There doesn't seem to be much point, anyway."

Safety two hundred yards away, Hardman was still moving strongly, undeterred by the furnace-like heat. He reached the first crest, partly hidden in the huge pails of steam which hung over the centre of the silt flat, fading into them like a man disappearing into a deep mist. The endless banks of the inland sea stretched out in front of him, merging at their edges into the incandescent sky so that to Kerans he seemed to be walking across dunes of whitehot ash into the very mouth of the sun.

For the next two hours he sat quietly in the museum, waiting for the cutter to arrive, listening to Riggs' irritated grumbling and Daley's lame excuses. Drained by the heat, Kerans tried to sleep, but the occasional crack of a carbine jolted through his bruised brain like the kick of a leather boot. Attracted by the sounds of the helicopter, a school of iguana had approached, and the reptiles were now sidling around the edges of the square, braying at the men on the steps of the museum. Their harsh shrieking voices filled Kerans with a dull fear that persisted even after the cutter's arrival and their return journey to the base. Sitting in the comparative coolness under the wire hood, the green banks of the channel sliding past, he could hear their raucous barks.

At the base he settled Wilson in the sick-bay, then sought out Dr. Bodkin and described the events of the morning, referring in pa.s.sing to the voices of the iguanas. Enigmatically, Bodkin only nodded to himself, then remarked: "Be warned, Robert, you may hear them again."

About Hardman's escape he made no comment.

Kerans' catamaran was still moored across the lagoon, so he decided to spend the night in his cabin at the testing station. There be pa.s.sed a quiet afternoon, nursing a light fever in his bunk, thinking of Hardman and his strange southward odyssey, and of the silt banks glowing like luminous gold in the meridian sun, both forbidding and inviting, like the lost but forever beckoning and unattainable sh.o.r.es of the amnionic paradise.

5 - Descent into Deep Time

Later that night, as Kerans lay asleep in his bunk at the testing station, the dark waters of the lagoon outside drifting through the drowned city, the first of the dreams came to him. He had left his cabin and walked out on to the deck, looking down over the rail at the black luminous disc of the lagoon. Dense palls of opaque gas swirled across the sky only a few hundred feet overhead, through which he could just discern the faint glimmering outline of a gigantic sun. Booming distantly, it sent dull glows pulsing across the lagoon, momentarily lighting the long limestone cliffs which had taken the place of the ring of white-faced buildings.

Reflecting these intermittent flares, the deep bowl of the water shone in a diffused opalescent blur, the discharged light of myriads of phosph.o.r.escing animalcula, congregating in dense shoals like a succession of submerged haloes. Between them the water was thick with thousands of entwined snakes and eels, writhing together in frantic tangles that tore the surface of the lagoon.

As the great sun drummed nearer, almost filling the sky itself, the dense vegetation along the limestone cliffs was flung back abruptly, to reveal the black and stone-grey heads of enormous Tria.s.sic lizards. Strutting forward to the edge of the cliffs, they began to roar together at the sun, the noise gradually mounting until it became indistinguishable from the volcanic pounding of the solar flares. Beating within him like his own pulse, Kerans felt the powerful mesmeric pull of the baying reptiles, and stepped out into the lake, whose waters now seemed an extension of his own blood stream. As the dull pounding rose, he felt the barriers which divided his own cells from the surrounding medium dissolving, and he swam forwards, spreading outwards across the black thudding water...

He woke in the suffocating metal box of his cabin, his head splitting like a burst marrow, too exhausted to open his eyes. Even as he sat on the bed, splashing his face in the luke-warm water from the jug, he could still see the vast inflamed disc of the spectral sun, still hear the tremendous drumming of its beat. Timing them, he realised that the frequency was that of his own heartbeats, but in some insane way the sounds were magnified so that they remained just above the auditory threshold, reverberating dimly off the metal walls and ceiling like the whispering murmur of some blind pelagic current against the hull-plates of a submarine.

The sounds seemed to pursue him as he opened the cabin door and moved down the corridor to the galley. It was shortly after 6 a.m. and the testing station stirred with a faint hollowed silence, the first flares of the false dawn illuminating the dusty reagent benches and the crates stacked under the fan-lights in the corridor. Several times Kerans paused and tried to shrug off the echoes that persisted in his ears, uneasily wondering what was the real ident.i.ty of his new pursuers. His unconscious was rapidly becoming a well-stocked pantheon of tutelary phobias and obsessions, homing onto his already over-burdened psyche like lost telepaths. Sooner or later the archetypes themselves would become restive and start fighting each other, anima against persona, ego against id...

Then he remembered that Beatrice Dahl had seen the same dream and pulled himself together. He went out onto the deck and looked across the slack water of the lagoon at the distant spire of the apartment block, trying to decide whether to borrow one of the scows moored to the jetty and drive over to her. Having now experienced one of the dreams, he realised the courage and self-sufficiency Beatrice had displayed, brushing off the least show of sympathy.

And yet Kerans knew that for some reason he had been reluctant to give Beatrice any real sympathy, cutting his questions about the nightmares as short as possible and never offering her treatment or sedative. Nor had he tried to follow up any of Bodkins' or Riggs' oblique remarks about the dreams and their danger, almost as if he had known that he would soon be sharing them, and accepted them as an inevitable element of his life, like the image of his own death each of them carried with him in the secret places of his heart. (Logically for what had a more gloomy prognosis than life?-every morning one should say to one's friends: 'I grieve for your irrevocable death', as to anyone suffering from an incurable disease, and was the universal omission of this minimal gesture of sympathy the model for their reluctance to discuss the dreams?) Bodkin was sitting at the table in the galley when Kerans entered, placidly drinking coffee brewing in a large cracked sauce-pan on the stove. His shrewd quick eyes watched Kerans un.o.btrusively as he lowered himself into a chair and ma.s.saged his forehead slowly with a febrile hand.

"So you're one of the dreamers now, Robert. You've beheld the fata morgana of the terminal lagoon. You look tired. Was it a deep one?

Kerans managed a rueful laugh. "Are you trying to frighten me, Alan? I wouldn't know yet, but it felt deep enough. G.o.d, I wish I hadn't spent last night here. There are no nightmares at the Ritz." He sipped pensively at the hot coffee. "So that's what Riggs was talking about. How many of his men are seeing these dreams?"

"Riggs himself doesn't, but at least half the others. And Beatrice Dahl, of course. I've been seeing them for a full three months. It's basically the same recurrent dream in all cases." Bodkin spoke in a slow unhurried voice, with a softer tone than his usual blunt delivery, as if Kerans had now become a member of a select inner group. "You've held out for a long time, Robert, it's quite a tribute to the strength of your preconscious filters. We were all beginning to wonder when you'd arrive." He smiled at Kerans. "Figuratively, of course. I've never discussed the dreams with anyone. Except for Hardman, and there, poor chap, the dreams were having him." As an afterthought he added: "You spotted the sun-pulse equation? Hardman's gramophone record was a play-back of his own pulse, amplified in the hope of precipitating the crisis then and there. Don't think I sent him out into those jungles deliberately."

Kerans nodded and gazed out through the window at the rounded bulk of the floating base moored alongside. High up on the top deck Sergeant Daley, the helicopter co-pilot, was standing motionless by the rail, staring across the cool early morning water. Perhaps he too had just woken from the same corporate nightmare, was filling his eyes with the olive-green spectrum of the lagoon in the forlorn expectation of erasing the burning image of the Tria.s.sic sun. Kerans looked down at the dark shadows below the table, seeing again the faint glimmer of the phosph.o.r.escing pools. Distantly in his ears he could hear the sun drumming over the sunken water. As he recovered from his first fears he realised that there was something soothing about its sounds, almost rea.s.suring and encouraging like his own heartbeats. But the giant reptiles had been terrifying.

He remembered the iguanas braying and lunging across the steps of the museum. Just as the distinction between the latent and manifest contents of the dream had ceased to be valid, so had any division between the real and the super-real in the external world. Phantoms slid imperceptibly from nightmare to reality and back again, the terrestrial and psychic landscapes were now indistinguishable, as they had been at Hiroshima and Auschwitz, Golgotha and Comorrah.

Skeptical of the remedy, he said to Bodkin: "You'd better lend me Hardman's alarm clock, Alan. Or better still, remind me to take a phen.o.barbitone tonight."

"Don't," Bodkin warned him firmly. "Not unless you want the impact doubled. Your residues of conscious control are the only thing holding up the dam." He b.u.t.toned his cotton jacket around his shirtless chest. "That wasn't a true dream, Robert, but an ancient organic memory millions of years old."

He pointed to the ascending rim of the sun through the groves of gymnospenns. "The innate releasing mechanisms laid down in your cytoplasm millions of years ago have been awakened, the expanding sun and the rising temperature are driving you back down the spinal levels into the drowned seas submerged beneath the lowest layers of your unconscious, into the entirely new zone of the neuronic psyche. This is the lumbar transfer, total biopsychic recall. We really remember these swamps and lagoons. After a few nights you won't be frightened of the dreams, despite their superficial horror. That's why Riggs has received orders for us to leave."

"The Pelycosaur...?" Kerans asked.

Bodkin nodded. "The joke was on us. The reason they didn't take the report seriously at Byrd was that ours wasn't the first to be reported."

Footsteps sounded up the companionway and moved briskly along the metal deck outside. Colonel Riggs pushed back the double swing doors, freshly scrubbed and breakfasted.

He waved his baton at them amiably, eyeing the litter of unwashed cups and his two reclining subordinates.

"G.o.d, what a pig hole! Morning to you both. We've got a busy day ahead of us so let's get our elbows off the table. I've fixed the departure time for twelve hundred hours tomorrow, and there'll be a final embarkation stand-by at ten hundred. I don't want to waste any more fuel than I have to, so dump everything you can overboard. You all right, Robert?"

"Perfectly," Kerans replied flatly, sitting up.

"Glad to hear it. You look a bit gla.s.sy. Right, then. If you want to borrow the cutter to evacuate the Ritz..."

Kerans listened to him automatically, watching the sun as it rose magnificently behind the gesticulating outline of the Colonel. What completely separated them now was the single fact that Riggs had not seen the dream, not felt its immense hallucinatory power. He was still obeying reason and logic, buzzing around his diminished, unimportant world with his little parcels of instructions like a worker bee about to return to the home nest. After a few minutes he ignored the Colonel completely and listened to the deep subliminal drumming in his ears, half-closed his eyes so that he could see the glimmering surface of the lake dapple across the dark underhang of the table.

Opposite him Bodkin appeared to be doing the same, his hands folded over his navel. During how many of their recent conversations had he in fact been miles away?

When Riggs left, Kerans followed him to the door. "Of course, Colonel, everything will be ready in good time. Thank you for calling."

As the cutter moved off across the lagoon he went back to his chair. For a few minutes the two men stared across the table at each other, the insects outside bouncing off the wire mesh as the sun lifted into the sky. At last Kerans spoke.

"Alan, I'm not sure whether I shall be leaving."

Without replying, Bodkin took out his cigarettes. He lit one carefully, then sat back smoking it calmly. "Do you know where we are?" he asked after a pause. "The name of this city?" When Kerans shook his head he said: "Part of it used to be called London, not that it matters. Curiously enough, though, I was born here yesterday I rowed over to the old University quarter, a ma.s.s of little creeks, actually found the laboratory where my father used to teach. We left here when I was six, but I can just remember being taken to meet him one day. A few hundred yards away there was a planetarium, I saw a performance once-that was before they bad to re-align the projector. The big dome is still there, about twenty feet below water. It looks like an enormous sh.e.l.l, fucus growing all over it, straight out of 'The Water Babies'. Curiously, looking down at the dome seemed to bring my childhood much nearer. To tell the truth I'd more or less forgotten it-at my age all you have are the memories of memories. After we left here our existence became completely nomadic, and in a sense this city is the only home I've ever known-" He broke off abruptly, his face suddenly tired.

"Go on," Kerans said evenly.

6 - The Drowned Ark

The two men moved quickly along the deck, their padded soles soundless on the metal plates. A white midnight sky hung across the dark surface of the lagoon, a few stationary clumps of c.u.mulus like sleeping galleons. The low night sounds of the jungle drifted over the water; occasionally a marmoset gibbered or the iguanas shrieked distantly from their eyries in the submerged office blocks. Myriads of insects festered along the water-line, momentarily disturbed as the swells rolled in against the base, slapping at the canted sides of the pontoon.

One by one Kerans began to cast off the restraining lines, taking advantage of the swells to lift the loops off the rusting bollards. As the station slowly pivoted away he looked up anxiously at the dark bulk of the base. Gradually the three nearside blades of the helicopter came into view above the top deck, then the slender tail rotor. He paused before releasing the last line, waiting for Bodkin to give the all-clear from the starboard bridge.

The tension on the line had doubled, and it took Kerans several minutes to work the metal loop up the curving lip of the bollard, the successive swells giving him a few inches of slack as the station tilted, followed a moment later by the base. Above him he could hear Bodkin whispering impatiently-they had swung right around into the narrow interval of water behind them and were now face on to the lagoon, the single light in Beatrice's penthouse burning on its pylon. Then he cleared the lip and lowered the heavy cable into the slack water three feet below, watching it cleave back towards the base.

Freed of its attendant burden, and with its centre of gravity raised by the helicopter on its roof, the huge drum rolled over a full five degrees from the vertical, then gradually regained its balance. A light in one of the cabins went on, then flicked off again after a few moments. Kerans seized the boathook on the deck beside him as the interval of open water widened, first to twenty yards, then to fifty. A low current moved steadily through the lagoons, and would carry them back along the sh.o.r.e to their former mooring.

Holding the station off from the buildings they skirted, now and then crushing the soft fern trees sprouting through the windows, they soon covered two hundred yards, slowing as the current diminished around the curve, and finally lodged in a narrow inlet about a hundred feet square in size.

Kerans leaned over the rail, looking down through the dark water at the small cinema theatre twenty feet below the surface, its flat roof luckily uncluttered by elevator-heads or fire escapes. Waving to Bodkin on the deck above, he stepped in through the laboratory and made his way past the specimen tanks and sinks to the companionway leading down to the float.

Only one stop-c.o.c.k had been built into the base of the float, but as he turned the handwheel a powerful jet of cold foaming water gushed up around his legs. By the time he returned to the lower deck, to make a final check of the laboratory, water was already spilling ankle-deep through the scuppers, sluicing among the sinks and benches. He quickly released the marmoset from its fume cupboard and pushed the bushy-tailed mammal through one of the windows. The station went down like an elevator, and he waded waistdeep to the companionway and climbed up to the next deck where Bodkin was exultantly watching the windows of the adjacent office blocks rise into the air.

They settled about three feet below deck level, on a flat keel with a convenient access point by the starboard bridge. Dimly below they could hear trapped air bubbling from the retorts and gla.s.sware in the laboratory, and a frothy stain spread across the water from a submerged window by one of the reagent benches.

Kerans watched the indigo bubbles fade and dissolve, thinking of the huge semi-circle of programme charts sinking below the water as he left the laboratory, a perfect, almost vaudevillian comment on the biophysical mechanisms they sought to describe, and which perhaps symbolised the uncertainties that lay ahead now that he and Bodkin had committed themselves to remaining behind. They were now entering the aqua incognita, with only a few rule of-thumb principles to guide them.

From the typewriter in his cabin Kerans took a sheet of paper, pinned it firmly to the door of the galley. Bodkin appended his signature to the message, and the two men went out on to the deck again and lowered Kerans' catamaran into the water.

Paddling slowly, the outboard shipped, they glided off across the black water, soon disappearing among the dark blue shadows along the edge of the lagoon.

As the down-draught from its blades fanned furiously across the swimming pool, tearing at the striped awning of the patio, the helicopter circled deafeningly over the penthouse, plunging and diving as it searched for a landing point. Kerans smiled to himself as he watched it through the plastic vanes over the lounge windows, confident that the tottering pile of kerosene drums he and Bodkin had pyramided over the roof would safely deter the pilot. One or two of the drums toppled down on to the patio and splashed into the pool, and the helicopter veered away and then came in more slowly, hovering steadily.

The pilot, Sergeant Daley, swung the fuselage around so that the hatch door faced the lounge windows, and the hatless figure of Riggs appeared in the doorway, two of the soldiers holding on to him as he bellowed into an electric megaphone.

Beatrice Dahl ran across to Kerans from her observation post at the far end of the lounge, cupping her ears from the din.

"Robert, he's trying to talk to us!"

Kerans nodded, the Colonel's voice completely lost in the engine roar. Riggs finished and the helicopter leaned backwards and soared away across the lagoon, taking the noise and vibration with it.

Kerans put his arm around Beatrice's shoulders, the bare oiled skin smooth under his fingers. 'Well, I think we have a pretty good idea what he was saying."

They went out on to the patio, waving up to Bodkin who had appeared from the elevator-house and was straightening the drums. Below them, on the opposite side of the lagoon, the upper deck and bridge of the scuttled testing station protruded from the water, a flotsam of hundreds of pieces of old note-paper eddying away from it. Standing by the rail, Kerans pointed to the yellow hull of the base moored by the Ritz in the furthest of the three central lagoons.

After a futile attempt to re-float the station, Riggs had set off at noon as planned, sending the cutter over to the apartment house where he a.s.sumed the two biologists were hiding. Finding the elevator out of order, his men had refused the alternative of a twenty-storey climb up the stairway-already a few iguanas had made their homes on the lower landings-so Riggs had finally tried to reach them with the helicopter. Balked there, he was now crashing the Ritz.

"Thank G.o.d he's left," Beatrice said fervently. "For some reason be really got on my nerves."

"You made that pretty plain. I'm surprised he didn't take a pot shot at you."

"But, darling, he was insufferable. All that stiff upper lip stuff and dressing for dinner in the jungle-a total lack of adaptability."

"Riggs was all right," Kerans remarked quietly. "He'll probably get by." Now that Riggs had gone he was aware of how dependent he had been on the Colonel's buoyancy and good humour. Without him the morale of the unit would have disintegrated in an instant. It remained to be seen whether Kerans could imbue his own little trio with the same degree of confidence and sense of purpose. Certainly it was up to him to be the leader; Bodkin was too old, Beatrice too self-immersed.

Kerans glanced at the thermo-alarm he wore next to his wrist.w.a.tch. It was after 3-30, but the temperature was still a hundred and ten degrees, the sun beating against his skin like a fist. They joined Bodkin and went into the lounge.

Resuming the action conference interrupted by the helicopter, Kerans said: "You've got about a thousand gallons left in the roof tank, Bea, enough for three months-or let's say two as we can expect it to get a lot hotter-and I recommend you to close down the rest of the apartment and move into here. You're on the north side of the patio so the elevator-house will protect you from the heavy rains when they come in on the southerly storms. Ten to one the shutters and air-seals along the bedroom walls will be breached. What about food, Alan? How long will the stocks in the deep freeze last?"

Bodkin pulled a distasteful face. 'Well, as most of the lambs' tongues in aspic have been eaten they now consist chiefly of bully beef, so you could say 'indefinitely'. However, if you're actually planning to eat the stuff-six months. But I'd prefer iguana."

"No doubt the iguana would prefer us. All right then, that seems pretty fair. Alan will be over in the station until the level rises, and I'll be holding out at the Ritz. Anything else?"

Beatrice wandered away around the sofa towards the bar. "Yes, darling. Shut up. You're beginning to sound like Riggs. The military manner doesn't suit you."

Kerans threw her a mock salute and strolled over to look at the painting by Ernst at the far end of the lounge, while Bodkin gazed down at the jungle through the window. More and more the two scenes were coming to resemble each other, and in turn the third nightscape each of them carried within his mind. They never discussed their dreams, the common zone of twilight where they moved at night like the phantoms in the Delvaux painting.

Beatrice had sat down in the sofa with her back to him, and shrewdly Kerans guessed that the present unity of the group would not be long maintained. Beatrice was right; the military manner did not suit him, his personality was too pa.s.sive and introverted, too self-centered. More important, though, they were entering a new zone, where the usual obligations and allegiances ceased to operate. Now that they had made their decision the bonds between them had already begun to fade, and it was not simply for reasons of convenience that they would live apart. Much as he needed Beatrice Dahl, her personality intruded upon the absolute freedom he required for himself. By and large, each of them would have to pursue his or her own pathway through the time jungles, mark their own points of no return. Although they might see one another occasionally, around the lagoons or at the testing station, their only true meeting ground would be in their dreams.

7 - Carnival of Alligators
