In the distance, somewhere beyond the drowned bulk of a large Gothic building half a mile to the south, a diesel engine coughed and surged. Kerans left the balcony, closing the wire door behind him, and went into the bathroom to shave. Water had long ceased to flow through the taps, but Kerans maintained a reservoir in the plunge bath, carefully purified in a home-made still on the roof and piped in through the window.
Although he was only forty, Kerans' beard had been turned white by the radio-fluorine in the water, but his bleached crew-cut hair and deep amber tan made him appear at least ten years younger. A chronic lack of appetite, and the new malarias, had shrunk the dry leathery skin under his cheekbones, emphasising the ascetic cast of his face. As he shaved he examined his features critically, feeling the narrowing planes with his fingers, kneading the altered musculature which was slowly transforming its contours and revealing a personality that had remained latent during his previous adult life. Despite his introspective manner, he now seemed more relaxed and equable than he could remember, his cool blue eyes surveying himself with ironic detachment. The slightly self-conscious absorption in his own world, with its private rituals and observances, had passed. If he kept himself aloof from Riggs and his men this was simply a matter of convenience rather than of misanthropy.
On the way out he picked a monographed cream silk shirt from the stack left in the wardrobe by the financier, and slipped into a pair of neatly pressed slacks with a Zurich label. Sealing the double doors behind him-the suite was effectively a glass box inside the outer brick walls-he made his way down the staircase.
He reached the landing stage as Colonel Riggs' cutter, a converted landing craft, pulled in against the catamaran. Riggs stood in the bows, a trim dapper figure, one booted foot up on the ramp, surveying the winding creeks and hanging jungles like an old-time African explorer.
"Good morning, Robert," he greeted Kerans, jumping down on to the swaying platform of fifty-gallon drums lashed inside a wooden frame. "Glad you're still here. I've got a job on my hands you can help me with. Can you take the day off from the station?"
Kerans helped him on to the concrete balcony that had once jutted from a seventh-floor suite. "Of course, Colonel. As a matter of fact, I have already."
Technically Riggs had overall authority for the testing station and Kerans should have asked his permission, but the relationship between the two men was without ceremony. They had worked together for over three years, as the testing station and its military escort moved slowly northward through the European lagoons, and Riggs was content to let Kerans and Bodkin get on with their work in their own fashion, sufficiently busy himself with the jobs of mapping the shifting keys and harbours and evacuating the last inhabitants. In the latter task he often needed Kerans' help, for most of the people still living on in the sinking cities were either psychopaths or suffering from malnutrition and radiation sickness.
In addition to running the testing station, Kerans served as the unit's medical officer. Many of the people they came across required immediate hospitalisation before being flown out in the helicopter to one of the large tank-landing craft ferrying refugees up to Camp Byrd. Injured military personnel marooned on an office block in a deserted swamp, dying recluses unable to separate their own identities from the cities where they had spent their lives, disheartened freebooters who had stayed behind to dive for loot-all these Riggs good-humouredly but firmly helped back to safety, Kerans ready at his elbow to administer an analgesic or tranquilliser. Despite his brisk military front, Kerans found the Colonel intelligent and sympathetic, and with a concealed reserve of droll humour. Sometimes he wondered whether to test this by telling the Colonel about Bodkin's Pelycosaur, but on the whole decided against it.
The sergeant concerned in the hoax, a dour conscientious Scotsman called Macready, had climbed up onto the wire cage that enclosed the deck of the cutter and was carefully sweeping away the heavy fronds and vines strewn across it. None of the three other men tried to help him; under their heavy tans their faces looked pinched and drawn, and they sat inertly in a row against a bulkhead. The continuous heat and the massive daily doses of antibiotics drained all energy from them.
As the sun rose over the lagoon, driving clouds of steam into the great golden pall, Kerans felt the terrible stench of the water-line, the sweet compacted smells of dead vegetation and rotting animal carcases. Huge flies spun by, bouncing off the wire cage of the cutter, and giant bats raced across the heating water towards their eyries in the ruined buildings. Beautiful and serene from his balcony a few minutes earlier, Kerans realised that the lagoon was nothing more than a garbage-filled swamp.
"Let's go up onto the deck," he suggested to Riggs, lowering his voice so that the others would not hear. "I'll buy you a drink."
"Good man. I'm glad to see you've really caught on to the grand manner." Riggs shouted at Macready: "Sergeant, I'm going up to see if I can get the Doctor's distillation unit to work." He winked at Kerans as Macready acknowledged this with a sceptical nod, but the subterfuge was harmless. Most of the men carried hip-flasks, and once they secured the sergeant's grudging approval they would bring them out and settle down placidly until the Colonel returned.
Kerans climbed over the window-sill into the bedroom overlooking the jetty. 'What's your problem, Colonel?"
"It's not _my_ problem. If anything, in fact, it's yours."
They trudged up the staircase, Riggs slapping with his baton at the vines entwined around the rail. "Haven't you got the elevator working yet? I always thought this place was over-rated." However, be smiled appreciatively when they stepped into the clear ivorycool air of the penthouse, and sat down thankfully in one of the gilt-legged Louis XV armchairs. "Well, this is very gracious. You know, Robert, I think you have a natural talent for beachcombing. I may move in here with you. Any vacancies?"
Kerans shook his head, pressing a tab in the wall and waiting as the cocktail bar disgorged itself from a fake bookcase. "Try the Hilton. The service is better."
The reply was jocular, but much as he liked Riggs he preferred to see as little of him as possible. At present they were separated by the intervening lagoons, and the constant clatter of the galley and armoury at the base were safely muffled by the jungle. Although he had known each of the twenty men in the unit for at least a couple of years, with the exception of Riggs and Sergeant Macready, and a few terse grunts and questions in the sickbay, he had spoken to none of them for six months. Even his contacts with Bodkin he kept to a minimum. By mutual consent the two biologists had dispensed with the usual pleasantries and small-talk that had sustained them for the first two years during their sessions of cataloguing and slide preparation at the laboratory.
This growing isolation and self-containment, exhibited by the other members of the unit and from which only the buoyant Riggs seemed immune, reminded Kerans of the slackening metabolism and biological withdrawal of all animal forms about to undergo a major metamorphosis. Sometimes he wondered what zone of transit he himself was entering, sure that his own withdrawal was symptomatic not of a dormant schizophrenia, but 0f a careful preparation for a radically new environment, with its own internal landscape and logic, where old categories of thought would merely be an encumbrance.
He handed a large Scotch to Riggs, then took his own over to the desk, self-consciously removed some of the books stacked over the radio console.
"Ever try listening to that thing?" Riggs asked, playfully introducing a hint of reproof into his voice.
"Never," Kerans said. "Is there any point? We know all the news for the next three million years."
