Beatrice helped him furl the awning, and stepped into the lounge as the flickering shadow of the helicopter filled the patio, the downdraught fanning across their shoulders.
"But what's happened, Robert? Why is Riggs so excited?"
Kerans shielded his head from the engine roar and stared out across the green-ringed lagoons stretching towards the horizon, a sudden spasm of anxiety twisting one corner of his mouth.
"He's not excited, just worried stiff. Everything is beginning to collapse around him. Lieutenant Hardman has disappeared!"
Like an immense putrescent sore, the jungle lay exposed below the open hatchway of the helicopter. Giant groves of gymnosperms stretched in dense clumps along the rooftops of the submerged buildings, smothering the white rectangular outlines. Here and there an old concrete water tower protruded from the morass, or the remains of a makeshift jetty still floated beside the hulk of a collapsing office block, overgrown with feathery acacias and flowering tamarisks. Narrow creeks, the canopies overhead turning them into green-lit tunnels, wound away from the larger lagoons, eventually joining the six hundred-yard-wide channels which broadened outwards across the former suburbs of the city. Everywhere the silt encroached, shoring itself in huge banks against a railway viaduct or crescent of offices, oozing through a submerged arcade like the fetid contents of some latter-day Cloaca Maxima. Many of the smaller lakes were now filled by the silt, yellow discs of funguscovered sludge from which a profuse tangle of competing plant forms emerged, walled gardens in an insane Eden.
Clamped securely to the cabin handrail by the nylon harness around his waist and shoulders, Kerans gazed down at the unfolding landscape, following the water-ways unwinding from the three central lagoons. Five hundred feet below the shadow of the helicopter raced across the mottled green surface of the water, and he focussed his attention on the area immediately around it. An immense profusion of animal life filled the creeks and canals: water-snakes coiled themselves among the crushed palisades of the water-logged bamboo groves, colonies of bats erupted out of the green tunnels like clouds of exploding soot, iguanas sat motionlessly on the shaded cornices like stone sphinxes. Often, as if disturbed by the noise of the helicopter, a human form seemed to dart and hide among the water-line windows, then revealed itself to be a crocodile snapping at a water-fowl, or one end of a subsiding log dislodged from the buffeted tree-ferns.
Twenty miles away the horizon was still obscured by the early morning mists, huge palls of golden vapour that hung from the sky like diaphanous curtains, but the air over the city was clear and vivid, the exhaust vapour of the helicopter sparkling as it receded in a long undulating signature. As they moved away from the central lagoons in their outward spiral sweep Kerans leaned against the hatchway and watched the glistening display, abandoning his search of the jungle below.
The chances of seeing Hardman from the air were infinitesimal. Unless he had taken refuge in a building near the base he would have been forced to travel along the water-ways, where he had the maximum possible protection from aerial observation under the overhanging fern trees.
In the starboard hatchway Riggs and Macready continued their vigil, passing a pair of binoculars to and fro. Without his peaked cap, his thin sandy hair blown forwards over his face, Riggs looked like a ferocious sparrow, his little jaw jutting fiercely at the open air.
He noticed Kerans gazing up at the sky and shouted: "Seen him yet, Doctor? Don't dawdle now, the secret of a successful sweep is one hundred percent cover, one hundred percent concentration."
Accepting the rebuke, Kerans scanned the tilting disc of the jungle again, the tall towers of the central lagoon pivoting around the hatchway. Hardman's disappearance had been discovered by a sick-bay orderly at 8 o'clock that morning, but his bed was cold and he had almost certainly left the previous evening, probably soon after the final ward-roll at 9-30. None of the smaller scows hitched to the jetty rail had gone, but Hardman could easily have lashed together a couple of the empty fuel drums stored in a pile by the C-Deck hold and lowered them noiselessly into the water. However crude, such a craft would paddle smoothly and carry him ten miles away by day-break, somewhere on the perimeter of a search area of some seventy-five square miles, every acre of which was honeycombed by derelict buildings.
Unable to see Bodkin before being winched aboard the helicopter, Kerans could only speculate about Hardman's motives for leaving the base, and whether these were part of a grander design maturing slowly in the Lieutenant's mind or merely a sudden meaningless reaction to the news that they were leaving the lagoons for the north. Kerans' initial excitement had evaporated, and he felt a curious sense of relief, as if one of the opposing lines of force that encircled him had been removed by Hardman's disappearance and the tension and impotence contained in the system suddenly released. If anything, however, the task of remaining behind would now be even more difficult.
Unshackling his harness, Riggs stood up with a gesture of exasperation and handed the binoculars to one of the two soldiers squatting on the floor at the rear of the cabin.
"Open searches are a waste of time over this type of terrain," he shouted at Kerans. 'We'll go down somewhere and have a careful look at the map, you can have a shot at reading Hardman's psychology."
They were about ten miles north-west of the central lagoons, the towers almost obscured in the mists along the horizon. Five miles away, directly between them and the base, was one of the two motor launches, cruising down an open channel, its white wake fading across the glass sheet of the water. Blocked by the urban concentration to the south, less silt had penetrated into the area, and the vegetation was lighter, more expanses of unbroken water between the principal lines of buildings. Altogether the zone below them was empty and uncongested, and Kerans felt convinced, though for no rational reason, that Hardman would not be found in the north-west sector.
Riggs climbed up into the cockpit and a moment later the speed and inclination of the helicopter altered. They began to make a shallow dive, swinging down to within a hundred feet of the water, glided in and out of the wide canals looking for a convenient rooftop on which to perch. Finally they picked out the humped back of a half-submerged cinema and let down slowly onto the square firm roof of the neo-assyrian portico.
For a few minutes they steadied their legs, gazing out over the expanses of blue water. The nearest structure was an isolated department store two hundred yards away, and the open vistas reminded Kerans of Herodotus' description of the landscape in Egypt at floodtime, with its rampart cities like the islands of the Aegean Sea.
Riggs opened his map wallet and spread the polythene print across the cabin floor. Resting his elbows on the edge of the hatchway, he put his finger on their present landing stage.
"Well, Sergeant," he told Daley, "we seem to be half-way back to Byrd. Apart from wearing out the engine we haven't achieved much."
Daley nodded, his small serious face hidden inside the fibre-glass helmet. "Sir, I think our only chance is to carry out low-level inspections over a few selected runs. There's just a hope we might see something—a raft or an oil patch."
"Agreed. But the problem is–" here Riggs drummed on the map with his baton "–where? Hardman is very probably no more than two or three miles from the base. What's your guess, Doctor?"
Kerans shrugged. "I don't really know what Hardman's motives are, Colonel. Latterly he'd been in Bodkin's charge. It may be... "
His voice began to trail off, and Daley cut in with another suggestion, distracting Riggs' attention. For the next five minutes the Colonel, Daley and Macready argued about possible routes Hardman had taken, marking only the wider water-ways as if Hardman were navigating a pocket battleship. Kerans looked around at the water eddying slowly past the cinema. A few branches and dumps of weed drifted along on the northward current, the bright sunlight masking the molten mirror of the surface. The water drummed against the portico beneath his feet, beating slowly against his mind, and setting up a widening circle of i
nterference patterns as if crossing it at an opposite direction to its own course of flow. He watched a succession of wavelets lapping at the sloping roof, wishing that be could leave the Colonel and walk straight down into the water, dissolve himself and the ever-present phantoms which attended him like sentinel birds in the cool bower of its magical calm, in the luminous, dragon-green, serpent-haunted sea.
Suddenly he realised without any shadow of doubt where Hardman was to be found.
He waited for Daley to finish. "...I knew Lieutenant Hardman, sir, flew nearly five thousand hours with him, he's obviously had a brain-storm. He wanted to get back to Byrd, must have decided he couldn't wait any longer, not even two days. He'll have headed north, be resting somewhere along these open channels out of the city."
Riggs nodded doubtfully, apparently unconvinced but prepared to accept the Sergeant's advice in default of any other.
"Well, you may be right. I suppose it's worth trying. What do you think, Kerans?"
Kerans shook his head. "Colonel, it's a complete waste of time searching the areas north of the city. Hardman wouldn't have come up here, it's too open and isolated. I don't know whether he's on foot or paddling a raft, but he certainly isn't going north—Byrd is the last place on Earth he wants to return to. There's only one direction in which Hardman is heading—south." Kerans pointed to the nexus of channels which flowed into the central lagoons, tributaries of a single huge water-way three miles south of the city, its passage indented and diverted by the giant silt banks. "Hardman will be somewhere along there. It probably took him all night to reach the main channel, and I should guess that he's resting in one of the small inlets before he moves on tonight."
He broke off and Riggs stared hard at the map, peaked cap pulled down over his eyes in a gesture of concentration.
"But why south?" Daley protested. "Once he leaves the channel there's nothing but solid jungle and open sea. The temperature is going up all the time—he'll fry."
Riggs looked up at Kerans. "Sergeant Daley has a point, Doctor. Why should Hardman choose to travel south?"
Looking out across the water again, Kerans replied in a flat voice: "Colonel, there isn't any other direction."
Riggs hesitated, then glanced at Macready, who had stepped back from the group and was standing beside Kerans, his tall stooped figure silhouetted like a gaunt crow against the water. Almost imperceptibly he nodded to Riggs, answering the unspoken question. Even Daley put a foot up on the cockpit entry step, accepting the logic of Kerans' argument and the shared understanding of Hardman's motives once Kerans had made them explicit.
Three minutes later the helicopter was speeding off at full manifold pressure towards the lagoons in the south.
As Kerans had prophesied, they found Hardman among the silt flats.
Descending to three hundred feet above the water, they began to rake up and down the distal five-mile length of the main channel. The huge banks of silt lifted above the surface like the backs of yellow sperm whales. Wherever the hydrodynamic contours of the channel gave the silt banks any degree of permanence, the surrounding jungle spilled from the rooftops and rooted itself in the damp loam, matting the whole morass into an immovable structure. From the hatchway Kerans scrutinised the narrow beaches under the outer edge of the fern trees, watching for the tell-tale signs of a camouflaged raft or make-shift hut.
After twenty minutes, however, and a dozen careful sweeps of the channel, Riggs turned from the hatchway with a rueful shake of his head.
"You're probably right, Robert, but it's a hopeless job. Hardman's no fool, if he wants to hide from us we'll never find him. Even if he were leaning out of a window and waving, ten to one we wouldn't see him."
Kerans murmured in reply, watching the surface below. Each of the tracking runs was about a hundred yards to the starboard of the previous one, and for the last three runs he had been watching the semi-circular crescent of what appeared to be a large apartment block standing in the angle between the channel and the southern bank of a small creek which ran off into the surrounding jungle. The upper eight or nine storeys of the block stood above the water, enclosing a iow mound of muddy-brown silt. The surface streamed with water draining away from a collection of shallow pools covering it. Two hours earlier the bank had been a sheet of wet mud, but by ten o'clock, as the helicopter flew over, the mud was beginning to dry and grow firm. To Kerans, shielding his eyes from the reflected sunlight, its smooth surface appeared to be scored by two faint parallel lines, about six feet apart, that led across to the jutting roof of an almost submerged balcony. As they swept overhead he tried to see under the concrete slab, but its mouth was choked with refuse and rotting logs.
He touched Riggs' arm and pointed to the tracks, so immersed in tracing their winding progress to the balcony that he almost failed to notice the equally distinct pattern of imprints emerging in the drying surface between the lines, spaced some four feet apart, unmistakably the footsteps of a tall powerful man hauling a heavy load.
As the noise of the helicopter's engine faded out on the roof above them, Riggs and Macready bent down and inspected the crude catamaran hidden behind a screen of bocage under the balcony. Fashioned from two drop tanks lashed to either end of a metal bed-frame, its twin grey hulls were still streaked with silt. Clumps of mud from Hardman's feet crossed the room opening onto the balcony and disappeared through the suite into the adjacent corridor.
"This is it without a doubt—agree, Sergeant?" Riggs asked, stepping out into the sunlight to look up at the crescent of apartment blocks. A chain of autonomous units, they were linked by short causeways between the elevator wells at the end of each building. Most of the windows were broken, the cream facing tiles covered by huge patches of fungus, and the whole complex looked like an over-ripe camembert cheese.
Macready knelt down by one of the hulls, cleaning away the silt, then traced out the code number painted across the bow. "UNAF 22-H-549—that's us, sir. The drop tanks were being cleared out yesterday, we'd stored them on C-Deck. He must have taken a spare bed from the sick-bay after ward-roll."
"Good." Rubbing his hands together with pleasure, Riggs stepped over to Kerans, smiling jauntily, his self-confidence and good humour fully restored. "Excellent, Robert. Superb diagnostic skill, you were quite right, of course." He peered shrewdly at Kerans, as if speculating on the real sources of this remarkable insight, invisibly marking him off. "Cheer up, Hardman will be grateful to you when we take him back."
Kerans stood on the edge of the balcony, the slope of caking silt below him. He looked up at the silent curve of windows, wondering which of the thousand or so rooms would be Hardman's hiding place. "I hope you're right. You've still got to catch him."
"Don't worry, we will." Riggs began to shout up at the two men on the roof, helping Daley lash down the helicopter. 'Wilson, keep a look-out from the south-west end; Caldwell, you work your way across to the north. Keep an eye on both sides, he might try to swim for it."
The two men saluted and moved off, their carbines held at their hips. Macready cradled a Thompson gun in the crook of his arm, and as Riggs unbuttoned the flap of his holster Kerans said quietly: "Colonel, we're not tracking down a wild dog."
Riggs waved this aside. "Relax, Robert, it's just that I don't want my leg bitten off by some sleeping croc. Though as a matter of interest–" here he flashed Kerans a gleaming smile "–Hardman has got a .45 Colt with him."
Leaving Kerans to digest this, he picked up the electric megaphone.
"HARDMAN!! THIS IS COLONEL RIGGS!!" He bellowed Hardman's name at the silent heat, then winked at Kerans and added: "DR. KERANS WANTS TO TALK TO YOU, LIEUTENANT!!"
Focussed by the crescent of buildings, the sounds echoed away across the swamps and creeks, booming distantly over the great empty mudflats. Around them everything glistened in the immense heat, and the men on the roof fretted nervously under their forage caps. A thick cloacal stench exuded from the silt flat, a corona of a million insects pulsing and hum
ming hungrily above it, and a sudden spasm of nausea knotted Kerans' gullet, for a moment dizzying him. Pressing a wrist tightly to his forehead, he leaned back against a pillar, listening to the echoes reverberate around him. Four hundred yards away two white-faced clock towers protruded through the vegetation, like the temple spires of some lost jungle religion, and the sounds of his name—"Kerans... Kerans... Kerans"—reflected off them seemed to Kerans to toll with an intense premonition of terror and disaster, the meaningless orientation of the clock hands identifying him, more completely than anything he bad previously experienced, with all the confused and minatory spectres that cast their shadows more and more darkly through his mind, the myriad-handed mandala of cosmic time.
His name still echoed faintly in his ears as they began their search of the building. He took up his position at the stairwell at the centre of each corridor while ffiggs and Macready inspected the apartments, keeping a look-out as they climbed the floors. The building had been gutted. All the floorboards had rotted or been ripped out, and they moved slowly along the tiled inlays, stepping warily from one concrete tie-beam to another. Most of the plaster had slipped from the walls and lay in grey heaps along the skirting boards. Wherever sunlight filtered through, the bare lathes were intertwined with creeper and wire-moss, and the original fabric of the building seemed solely supported by the profusion of vegetation ramifying through every room and corridor.
Through the cracks in the floors rose the stench of the greasy water swirling through the windows below. Disturbed for the first time in many years, the bats which hung from the tilting picture rails flew frantically for the windows, dispersing with cries of pain in the brilliant sunlight. Lizards scuttered and darted through the floor cracks, or skated desperately around the dry baths in the bathrooms.
