"You don't. Really, you should switch it on just now and then. Hear all sorts of interesting things." He put his drink down and sat forward. "For example, this morning you would have heard that exactly three days from now we're packing up and leaving for good." He nodded when Kerans looked around in surprise. "Came through last night from Byrd. Apparently the water level is still rising, all the work we've done has been a total waste-as I've always maintained, incidentally. The American and Russian units are being recalled as well. Temperatures at the Equator are up to one hundred and eighty degrees now, going up steadily, and the rain belts are continuous as high as the 20th parallel. There's more silt too-"
He broke off, watching Kerans speculatively. 'What's the matter? Aren't you relieved to be going?"
"Of course," Kerans said automatically. He was holding an empty glass, and walked across the room, intending to put it on the bar, instead found himself absent-mindedly touching the clock over the mantelpiece. He seemed to be searching the room for something. "Three days, you said?"
"What do you want-three million?" Riggs grinned broadly. "Robert, I think you secretly want to stay behind."
Kerans reached the bar and filled his glass, collecting himself. He had oniy managed to survive the monotony and boredom of the previous year by deliberately suspending himself outside the normal world of time and space, and the abrupt return to earth had momentarily disconcerted him. In addition, he knew, there were other motives and responsibilities.
"Don't be absurd," he replied easily. "I simply hadn't realised that we might withdraw at such short notice. Naturally I'm glad to be going. Though I admit I have enjoyed being here." He gestured at the suite around them. "Perhaps it appeals to my _fin de siecle_ temperament. Up at Camp Byrd I'll be living in half a mess tin. The nearest I'll ever get to this sort of thing will be 'Bouncing with Beethoven' on the local radio show."
Riggs roared at this display of disgruntled humour, then stood up, buttoning his tunic. "Robert, you're a strange one."
Kerans finished his drink abruptly. "Look, Colonel, I don't think I'll be able to help you this morning after all. Something rather urgent has come up." He noticed Riggs nodding slowly. "Oh, I see. That was your problem. _My_ problem."
"Right. I saw her last night, and again this morning after the news came through. You'll have to convince her, Robert. At present she refuses point-blank to go. She doesn't realise that this time is the end, that there'll be no more holding units. She may be able to hang on for another six months, but next March, when the rain belts reach here, we won't even be able to get a helicopter in. Anyway, by then no-one will care. I told her that and she just walked away."
Kerans smiled bleakly, visualising the familiar swirl of hip and haughty stride. "Beatrice can be difficult sometimes," he temporised, hoping that she hadn't offended Riggs. It would probably take more than three days to change her mind and he wanted to be sure that the Colonel would still be waiting. "She's a complex person, lives on many levels. Until they all synchronise she can behave as if she's insane."
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, the ring of massive plants around them seeming 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 re-occupy 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 2 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 toward 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, rekindling 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 curb. 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.
