They left the suite, Kerans sealing the air-locks and setting the thermostat alarms so that the air would be a pleasant eighty degrees in two hours’ time. They made their way down to the landing-stage, Riggs pausing occasionally to savour the cool gilded air in one of the public drawing-rooms overlooking the lagoon, hissing at the snakes which glided softly among the damp, fungus-covered settees. They stepped into the cutter and Macready slammed the door of the cage behind them.
Five minutes later, the catamaran gliding and swirling behind the cutter, they set off from the hotel across the lagoon. Golden waves glimmered up into the boiling air, and the ring of massive plants around them seemed to dance in the heat gradients like a voodoo jungle.
Riggs peered sombrely through the cage. “Thank God for that signal from Byrd. We should have got out years ago. All this detailed mapping of harbours for use in some hypothetical future is absurd. Even if the solar flares subside it will be ten years before there’s any serious attempt to reoccupy these cities. By then most of the bigger buildings will have been smothered under the silt. It’ll take a couple of divisions to clear the jungle away from this lagoon alone. Bodkin was telling me this morning that already some of the canopies—of non-lignified plants, mark you—are over two hundred feet high. The whole place is nothing but a confounded zoo.”
He took off his peaked cap and rubbed his forehead, then shouted across the mounting roar of the two outboard diesels: “If Beatrice stays here much longer she will be insane. By the way, that reminds me of another reason why we’ve got to get out.” He glanced across at the tall lonely figure of Sergeant Macready at the tiller, staring fixedly at the breaking water, and at the pinched haunted faces of the other men. “Tell me, Doctor, how do you sleep these days?”
Puzzled, Kerans turned to look at the Colonel, wondering whether the question obliquely referred to his relationship with Beatrice Dahl. Riggs watched him with his bright intelligent eyes, baton flexed between his neat hands. “Very soundly,” he replied carefully. “Never better. Why do you ask?”
But Riggs merely nodded and began to shout instructions at Macready.
CHAPTER TWO THE COMING OF THE IGUANAS
SCREECHING LIKE A dispossessed banshee, a large hammer-nosed bat soared straight out of one of the narrow inlets off the creek and swerved straight towards the cutter. Its sonar confused by the labyrinth of giant webs spun across the inlet by the colonies of wolf spiders, it missed the wire hood above Kerans’ head by only a few feet, and then sailed away along the line of submerged office blocks, gliding in and out of the huge sail-like fronds of the fern-trees sprouting from their roofs. Suddenly, as it passed one of the projecting cornices, a motionless stone-headed creature snapped out and plucked the bat from the air. There was a brief piercing squawk and Kerans caught a glimpse of the crushed wings clamped in the lizard’s jaws. Then the reptile shrank back invisibly among the foliage.
All the way down the creek, perched in the windows of the office blocks and department stores, the iguanas watched them go past, their hard frozen heads jerking stiffly. They launched themselves into the wake of the cutter, snapping at the insects dislodged from the air-weed and rotting logs, then swam through the windows and clambered up the staircases to their former vantage-points, piled three deep across each other. Without the reptiles, the lagoons and the creeks of office blocks half-submerged in the immense heat would have had a strange dream-like beauty, but the iguanas and basilisks brought the fantasy down to earth. As their seats in the one-time boardrooms indicated, the reptiles had taken over the city. Once again they were the dominant form of life.
Looking up at the ancient impassive faces, Kerans could understand the curious fear they roused, re-kindling archaic memories of the terrifying jungles of the Paleocene, when the reptiles had gone down before the emergent mammals, and sense the implacable hatred one zoological class feels towards another that usurps it.
At the end of the creek they entered the next lagoon, a wide circle of dark green water almost half a mile in diameter. A lane of red plastic buoys marked a channel towards an opening on the far side. The cutter had a draught of little more than a foot, and as they moved along through the flat water, the sun slanting down behind them opening up the submerged depths, they could see the clear outlines of five-and six-storey buildings looming like giant ghosts, here and there a moss-covered roof breaking the surface as the swell rolled past it.
Sixty feet below the cutter a straight grey promenade stretched away between the buildings, the remains of some former thoroughfare, the rusting humped shells of cars still standing by the kerb. Many of the lagoons in the centre of the city were surrounded by an intact ring of buildings, and consequently little silt had entered them. Free of vegetation, apart from a few drifting clumps of Sargasso weed, the streets and shops had been preserved almost intact, like a reflection in a lake that has somehow lost its original.
The bulk of the city had long since vanished, and only the steel-supported buildings of the central commercial and financial areas had survived the encroaching flood waters. The brick houses and single-storey factories of the suburbs had disappeared completely below the drifting tides of silt. Where these broke surface giant forests reared up into the burning dull-green sky, smothering the former wheatfields of temperate Europe and North America. Impenetrable Mato Grossos sometimes three hundred feet high, they were a nightmare world of competing organic forms returning rapidly to their Paleozoic past, and the only avenues of transit for the United Nations military units were through the lagoon systems that had superimposed themselves on the former cities. But even these were now being clogged with silt and then submerged.
Kerans could remember the unending succession of green twilights that had settled behind them as he and Riggs moved slowly northward across Europe, leaving one city after another, the miasmic vegetation swamping the narrow canals and crowding from roof-top to roof-top.
Now they were to abandon yet another city. Despite the massive construction of the main commercial buildings, it consisted of little more than three principal lagoons, surrounded by a nexus of small lakes fifty yards in diameter and a network of narrow creeks and inlets which wound off, roughly following the original street-plan of the city, into the outlying jungle. Here and there they vanished altogether or expanded into the steaming sheets of open water that were the residues of the former oceans. In turn these gave way to the archipelagoes that coalesced to form the solid jungles of the southern massif.
The military base set up by Riggs and his platoon, which harboured the biological testing station, was in the most southerly of the three lagoons, sheltered by a number of the tallest buildings of the city, thirty-storey blocks in what had once been the down-town financial sector.
As they crossed the lagoon the yellow-striped drum of the floating base was on its sun-ward side, almost obscured in the reflected light, the rotating blades of the helicopter on its roof throwing brilliant lances across the water at them. Two hundred yards down shore was the smaller white-painted hull of the biological testing station, moored against a broad hump-backed building which had formerly been a concert hall.
Kerans gazed up at the rectangular cliffs, enough of the windows intact to remind him of the illustrations of sundazzled promenades at Nice, Rio and Miami he had read about as a child in the encyclopaedias at Camp Byrd. Curiously, though, despite the potent magic of the lagoon worlds and the drowned cities, he had never felt any interest in their contents, and never bothered to identify in which of the cities he was stationed.
Dr. Bodkin, twenty-five years his senior, had actually lived in several of them, both in Europe and America, and spent most of his spare time punting around the remoter water-ways, searching out former libraries and museums. Not that they contained anything other than his memories.
Perhaps it was this absence of personal memories that made Kerans indifferent to the spectacle of these sinking civilisations. He had been born and brought up entirely
