'Not in a conscious sense. But the various groups which comprise the Nambikwaras are permanently feuding with each other, and this far from the settlement we might easily be involved in an opportunist attack. Once we get to the settlement we'll be all right there's a sort of precarious equilibrium there. But even so, have your wits about you. As you'll see, they're as nervous as birds.'

'How does Ryker manage to keep out of their way? Hasn't he been here for years?'

'About twelve.' Pereira sat down on the gunwale and eased his peaked cap off his forehead. 'Ryker is something of a special case. Temperamentally he's rather explosive I meant to warn you to handle him carefully, he might easily whip up an incident but he seems to have manoeuvred himself into a position of authority with the tribe. In some ways he's become an umpire, arbitrating in their various feuds. How he does it I haven't discovered yet; it's quite uncharacteristic of the Indians to regard a white man in that way. However, he's useful to us, we might eventually set up a mission here. Though that's next to impossible we tried it once and the Indians just moved 500 miles away.'

Connolly looked back at the derelict landing stage as it disappeared around a bend, barely distinguishable from the jungle, which was as dilapidated as this sole mournful artifact.

'What on earth made Ryker come out here?' He had heard something in Brasilia of this strange figure, sometime journalist and man of action, the selfproclaimed world citizen who at the age of fortytwo, after a life spent venting his spleen on civilization and its gimcrack gods, had suddenly disappeared into the Amazonas and taken up residence with one of the aboriginal tribes. Most latterday Gauguins were absconding confidence men or neurotics, but Ryker seemed to be a genuine character in his own right, the last of a race of true individualists retreating before the barbedwire fences and regimentation of 20thcentury life. But his chosen paradise seemed pretty scruffy and degenerate, Connolly reflected, when one saw it at close quarters. However, as long as the man could organize the Indians into a few search parties he would serve his purpose. 'I can't understand why Ryker should pick the Amazon basin. The South Pacific yes, but from all I've heard and you've confirmed just now the Indians appear to be a pretty diseased and miserable lot, hardly the noble savage.'

Captain Pereira shrugged, looking away across the oily water, his plump sallow face mottled by the lacelike shadow of the wire netting. He belched discreetly to himself, and then adjusted his holster belt. 'I don't know the South Pacific, but I should guess it's also been oversentimentalized. Ryker didn't come here for a scenic tour. I suppose the Indians are diseased and, yes, reasonably miserable. Within fifty years they'll probably have died out. But for the time being they do represent a certain form of untamed, natural existence, which after all made us what we are. The hazards facing them are immense, and they survive.' He gave Connolly a sly smile. 'But you must argue it out with Ryker.'

They lapsed into silence and sat by the rail, watching the river unfurl itself. Exhausted and collapsing, the great trees crowded the banks, the dying expiring among the living, jostling each other aside as if for a last despairing assault on the patrol boat and its passengers. For the next half an hour, until they opened their lunch packs, Connolly searched the treetops for the giant bifurcated parachute which should have carried the capsule to earth. Virtually impermeable to the atmosphere, it would still be visible, spreadeagled like an enormous bird over the canopy of leaves. Then, after drinking a can of Pereira's beer, he excused himself and went down to the cabin.

The two steel cases containing the monitoring equipment had been stowed under the chart table, and he pulled them out and checked that the moistureproof seals were still intact. The chances of making visual contact with the capsule were infinitesimal, but as long as it was intact it would continue to transmit both a sonar and radio beacon, admittedly over little more than twenty miles, but sufficient to identify its whereabouts to anyone in the immediate neighbourhood. However, the entire northern half of the South Americas had been covered by successive aerial sweeps, and it seemed unlikely that the beacons were still operating. The disappearance of the capsule argued that it had sustained at least minor damage, and by now the batteries would have been corroded by the humid air.

Recently certain of the UN Space Department agencies had begun to circulate the unofficial view that Colonel Spender had failed to select the correct attitude for reentry and that the capsule had been vaporized on its final descent, but Connolly guessed that this was merely an attempt to pacify world opinion and prepare the way for the resumption of the space programme. Not only the Lake Maracaibo Dredging Project, but his own presence on the patrol boat, indicated that the Department still believed Colonel Spender to be alive, or at least to have survived the landing. His final reentry orbit should have brought him down into the landing zone 500 miles to the east of Trinidad, but the last radio contact before the ionization layers around the capsule severed transmission indicated that he had undershot his trajectory and come down somewhere on the South American landmass along a line linking Lake Maracaibo with Brasilia.

Footsteps sounded down the companionway, and Captain Pereira lowered himself into the cabin. He tossed his hat onto the chart table and sat with his back to the fan, letting the air blow across his fading hair, carrying across to Connolly a sweet unsavoury odour of garlic and cheap pomade.

'You're a sensible man, Lieutenant. Anyone who stays up on deck is crazy. However,' he indicated Connolly's pallid face and hands, a memento of a long winter in New York 'in a way it's a pity you couldn't have put in some sunbathing. That metropolitan pallor will be quite a curiosity to the Indians.' He smiled agreeably, showing the yellowing teeth which made his olive complexion even darker. 'You may well be the first white man in the literal sense that the Indians have seen.'

'What about Ryker? Isn't he white?'

'Black as a berry now. Almost indistinguishable from the Indians, apart from being 7 feet tall.' He pulled over a collection of cardboard boxes at the far end of the seat and began to rummage through them. Inside was a collection of miscellaneous oddments balls of thread and raw cotton, lumps of wax and resin, urucu paste, tobacco and seedbeads. 'These ought to assure them of your good intentions.'

Connolly watched as he fastened the boxes together. 'How many search parties will they buy? Are you sure you brought enough? I have a fiftydollar allocation for gifts.'

'Good,' Pereira said matteroffactly. 'We'll get some more beer. Don't worry, you can't buy these people, Lieutenant. You have to rely on their goodwill; this rubbish will put them in the right frame of mind to talk.'

Connolly smiled dourly. 'I'm more keen on getting them off their hunkers and out into the bush. How are you going to organize the search parties?'

'They've already taken place.'

'What?' Connolly sat forward. 'How did that happen? But they should have waited' he glanced at the heavy monitoring equipment 'they can't have known what '

Pereira silenced him with a raised hand. 'My dear Lieutenant. Relax, I was speaking figuratively. Can't you understand, these people are nomadic, they spend all their lives continually on the move. They must have covered every square foot of this forest a hundred times in the past five years. There's no need to send them out again. Your only hope is that they may have seen something and then persuade them to talk.'

Connolly considered this, as Pereira unwrapped another parcel. 'All right, but I may want to do a few patrols. I can't just sit around for three days.'

'Naturally. Don't worry, Lieutenant. If your astronaut came down anywhere within 500 miles of here they'll know about it.' He unwrapped the parcel and removed a small teak cabinet. The front panel was slotted, and lifted to reveal the face of a large ormolu table clock, its Gothic hands and numerals below a gilded belldome. Captain Pereira compared its time with his wristwatch. 'Good. Running perfectly, it hasn't lost a second in fortyeight hours. This should put us in Ryker's good books.'

Connolly shook his head. 'Why on earth does he want a clock? I thought the man had turned his back on such things.'

Pereira packed the tooled metal face away. 'Ah, well, whenever we escape from anything we always carry a memento of it with us. Ryker collects clocks; this is the third I've bought for him. God knows what he does with them.'

The launch had changed course, and was moving in a wide circle across the river, the current whispering in a tender rippling murmur across the hull. They made their way up onto the deck, where the helmsman was unshackling several sections of the wire mesh in order to give himself an uninterrupted view of the bows. The two sailors climbed through the aperture and took up their positions fore and aft, boathooks at the ready.

They had entered a large bowshaped extension of the river, where the current had overflowed the bank and produced a series of lowlying mud flats. Some two or three hundred yards wide, the water seemed to be almost motionless, seeping away through the trees which defined its margins so that the exit and inlet of the river were barely perceptible. At the inner bend of the bow, on the only firm ground, a small cantonment of huts had been built on a series of wooden palisades jutting out over the water. A narrow promontory of forest reached to either side of the cantonment, but a small area behind it had been cleared to form an open campong. On its far side were a number of wattle storage huts, a few dilapidated shacks and hovels of dried palm.

The entire area seemed deserted, but as they approached, the cutwater throwing a fine plume of white spray across the glassy swells, a few Indians appeared in the shadows below the creepers trailing over the jetty, watching them stonily. Connolly had expected to see a group of tall broadshouldered warriors with white markings notched across their arms and cheeks, but these Indians were puny and degenerate, their pinched faces lowered beneath their squat bony skulls. They seemed undernourished and depressed, eyeing the visitors with a sort of sullen watchfulness, like pariah dogs from a gutter.

Pereira was shielding his eyes from the sun, across whose inclining path they were now moving, searching the ramshackle bungalow built of woven rattan at the far end of the jetty.

'No signs of Ryker yet. He's probably asleep or drunk.' He noticed Connolly's distasteful frown. 'Not much of a place, I'm afraid.'

As they moved towards the jetty, the wash from the launch slapping at the greasy bamboo poles and throwing a gust of foul air into their faces, Connolly looked back across the open disc of water, into which the curving wake of the launch was dissolving in a final summary of their long voyage upriver to the derelict settlement, fading into the slack brown water like a last tenuous thread linking him with the order and sanity of civilization. A strange atmosphere of emptiness hung over this inland lagoon, a fiat pall of dead air that in a curious way was as menacing as any overt signs of hostility, as if the crudity and violence of all the Amazonian jungles met here in a momentary balance which some untoward movement of his own might upset, unleashing appalling forces. Away in the distance, downshore, the great trees leaned like corpses into the glazed air, and the haze over the water embalmed the jungle and the late afternoon in an uneasy stillness.

They bumped against the jetty, rocking lightly into the palisade of poles and dislodging a couple of waterlogged outriggers lashed together. The helmsman reversed the engine, waiting for the sailors to secure the lines. None of the Indians had come forward to assist them. Connolly caught a glimpse of one old simian face regarding him with a rheumy eye, riddled teeth nervously worrying a pouchlike lower lip.

He turned to Pereira, glad that the Captain would be interceding between himself and the Indians. 'Captain, I should have asked before, but are these Indians cannibalistic?'

Pereira shook his head, steadying himself against a stanchion. 'Not at all. Don't worry about that, they'd have been extinct years ago if they were.'

'Not even white men?' For some reason Connolly found himself placing a peculiarly indelicate emphasis upon the word 'white'.

Pereira laughed, straightening his uniform jacket. 'For God's sake, Lieutenant, no. Are you worrying that your astronaut might have been eaten by them?'

'I suppose it's a possibility.'

'I assure you, there have been no recorded cases. As a matter of interest, it's a rare practice on this continent. Much more typical of Africa and Europe,' he added with sly humour. Pausing to smile at Connolly, he said quietly, 'Don't despise the Indians, Lieutenant. However diseased and dirty they may be, at least they are in equilibrium with their environment. And with themselves. You'll find no Christopher Columbuses or Colonel Spenders here, but no Belsens either. Perhaps one is as much a symptom of unease as the other?'

They had begun to drift down the jetty, overrunning one of the outriggers, whose bow creaked and disappeared under the stern of the launch, and Pereira shouted at the helmsman: 'Ahead, Sancho! More ahead! Damn Ryker, where is the man?'

Churning out a niagara of boiling brown water, the launch moved forward, driving its shoulder into the bamboo supports, and the entire jetty sprung lightly under the impact. As the motor was cut and the lines finally secured, Connolly looked up at the jetty above his head.

Scowling down at him, an expression of bilious irritability on his heavyjawed face, was a tall barechested man wearing a pair of frayed cotton shorts and a sleeveless waistcoat of pleated raffia, his dark eyes almost hidden by a widebrimmed straw hat. The heavy muscles of his exposed chest and arms were the colour of tropical teak, and the white scars on his lips and the fading traces of the heat ulcers which studded his shin bones provided the only lighter colouring. Standing there, arms akimbo with a sort of jaunty arrogance, he seemed to represent to Connolly that quality of untamed energy which he had so far found so conspicuously missing from the forest.

Completing his scrutiny of Connolly, the big man bellowed: 'Pereira, for God's sake, what do you think you're doing? That's my bloody outrigger you've just run down! Tell that steersman of yours to get the cataracts out of his eyes or I'll put a bullet through his backside!'

Grinning goodhumouredly, Pereira pulled himself up on to the jetty. 'My dear Ryker, contain yourself. Remember your bloodpressure.' He peered down at the waterlogged hulk of the derelict canoe which was now ejecting itself slowly from the river. 'Anyway, what good is a canoe to you, you're not going anywhere.'

Grudgingly, Ryker shook Pereira's hand. 'That's what you like to think, Captain. You and your confounded Mission, you want me to do all the work. Next time you may find I've gone a thousand miles upriver. And taken the Nambas with me.'

'What an epic prospect, Ryker. You'll need a Homer to celebrate it.' Pereira turned and gestured Connolly on to the jetty. The Indians were still hanging about listlessly, like guilty intruders.

Ryker eyed Connolly's uniform suspiciously. 'Who's this? Another socalled anthropologist, sniffing about for smut? I warned you last time, I will not have any more of those.'

'No, Ryker. Can't you recognize the uniform? Let me introduce Lieutenant Connolly, of that brotherhood of latterday saints, by whose courtesy and generosity we live in peace together the United Nations.'

'What? Don't tell me they've got a mandate here now? God above, I suppose he'll bore my head off about cereal/protein ratios!' His ironic groan revealed a concealed reserve of acid humour.

'Relax. The Lieutenant is very charming and polite. He works for the Space Department, Reclamation Division. You know, searching for lost aircraft and the like. There's a chance you may be able to help him.' Pereira winked at Connolly and steered him forward. 'Lieutenant, the Rajah Ryker.'

'I doubt it,' Ryker said dourly. They shook hands, the corded muscles of Ryker's fingers like a trap. Despite his thicknecked stoop, Ryker was a good six to ten inches taller than Connolly. For a moment he held on to Connolly's hand, a slight trace of wariness revealed below his mask of bad temper. 'When did this plane come down?' he asked. Connolly guessed that he was already thinking of a profitable salvage operation.

'Some time ago,' Pereira said mildly. He picked up the parcel containing the cabinet clock and began to stroll after Ryker towards the bungalow at the end of the jetty. A loweaved dwelling of woven rattan, its single room was surrounded on all sides by a veranda, the overhanging roof shading it from the sunlight. Creepers trailed across from the surrounding foliage, involving it in the background of palms and fronds, so that the house seemed a momentary formalization of the jungle.

'But the Indians might have heard something about it,' Pereira went on. 'Five years ago, as a matter of fact.'

Ryker snorted. 'My God, you've got a hope.' They went up the steps on to the veranda, where a slimshouldered Indian youth, his eyes like moist marbles, was watching from the shadows. With a snap of irritation, Ryker cupped his hand around the youth's pate and propelled him with a backward swing down the steps. Sprawling on his knees, the youth picked himself up, eyes still fixed on Connolly, then emitted what sounded like a highpitched nasal hoot, compounded partly of fear and partly of excitement. Connolly looked back from the doorway, and noticed that several other Indians had stepped onto the pier and were watching him with the same expression of rapt curiosity.

Pereira patted Connolly's shoulder. 'I told you they'd be impressed. Did you see that, Ryker?'

Ryker nodded curtly, as they entered his livingroom pulled off his straw hat and tossed it on to a couch under the window. The room was dingy and cheerless. Crude bamboo shelves were strung around the walls, ornamented with a few primitive carvings of ivory and bamboo. A couple of rocking chairs and a cardtable were in the centre of the room, dwarfed by an immense Victorian mahogany dresser standing against the rear wall. With its castellated mirrors and ornamental pediments it looked like an altarpiece stolen from a cathedral. At first glance it appeared to be leaning to one side, but then Connolly saw that its rear legs had been carefully raised from the tilting floor with a number of small wedges. In the centre of the dresser, its multiple reflections receding to infinity in a pair of small wing mirrors, was a cheap threedollar alarm clock, ticking away loudly. An overandunder Winchester shotgun leaned against the wall beside it.

Gesturing Pereira and Connolly into the chairs, Ryker raised the blind over the rear window. Outside was the compound, the circle of huts around its perimeter. A few Indians squatted in the shadows, spears upright between their knees.

Connolly watched Ryker moving about in front of him, aware that the man's earlier impatience had given away to a faint but noticeable edginess. Ryker glanced irritably through the window, apparently annoyed to see the gradual gathering of the Indians before their huts.

There was a sweetly unsavoury smell in the room, and over his shoulder Connolly saw that the cardtable was loaded with a large bale of miniature animal skins, those of a vole or some other forest rodent. A halfhearted attempt had been made to trim the skins, and tags of clotted blood clung to their margins.

Ryker jerked the table with his foot. 'Well, here you are,' he said to Pereira. 'Twelve dozen. They took a hell of a lot of getting, I can tell you. You've brought the clock?'

Pereira nodded, still holding the parcel in his lap. He gazed distastefully at the dank scruffy skins. 'Have you got some rats in there, Ryker? These don't look much good. Perhaps we should check through them outside..

'Dammit, Pereira, don't be a fool!' Ryker snapped. 'They're as good as you'll get. I had to trim half the skins myself. Let's have a look at the clock.'

'Wait a minute.' The Captain's jovial, easygoing manner had stiffened. Making the most of his temporary advantage, he reached out and touched one of the skins gingerly, shaking his head. 'Pugh... Do you know how much I paid for this clock, Ryker? Seventyfive dollars. That's your credit for three years. I'm not so sure. And you're not very helpful, you know. Now about this aircraft that may have come down '

Ryker snapped his fingers. 'Forget it. Nothing did. The Nambas tell me everything.' He turned to Connolly. 'You can take it from me there's no trace of an aircraft around here. Any rescue mission would be wasting their time.'

Pereira watched Ryker critically. 'As a matter of fact it wasn't an aircraft.' He tapped Connolly's shoulder flash. 'It was a rocket capsule with a man on board. A very important and valuable man. None other than the Moon pilot, Colonel Francis Spender.'

'Well...' Eyebrows raised in mock surprise, Ryker ambled to the window, stared out at a group of Indians who had advanced halfway across the compound. 'My God, what next! The Moon pilot. Do they really think he's around here? But what a place to roost.' He leaned out of the window and bellowed at the Indians, who retreated a few paces and then held their ground. 'Damn fools,' he muttered, 'this isn't a zoo.'

Pereira handed him the parcel, watching the Indians. There were more than fifty around the compound now, squatting in their doorways, a few of the younger men honing their spears. 'They are remarkably curious,' he said to Ryker, who had taken the parcel over to the dresser and was unwrapping it carefully. 'Surely they've seen a paleskinned man before?'

'They've nothing better to do.' Ryker lifted the clock out of the cabinet with his big hands, with great care placed it beside the alarm clock, the almost inaudible motion of its pendulum lost in the metallic chatter of the latter's escapement. For a moment he gazed at the ornamental hands and numerals. Then he picked up the alarm clock and with an almost valedictory pat, like an officer dismissing a faithful if stupid minion, locked it away in the cupboard below. His former buoyancy returning, he gave Pereira a playful slap on the shoulder. 'Captain, if you want any more ratskins just give me a shout!'

Backing away, Pereira's heel touched one of Connolly's feet, distracting Connolly from a problem he had been puzzling over since their entry into the hut. Like a concealed clue in a detective story, he was sure that he had noticed something of significance, but was unable to identify it.

'We won't worry about the skins,' Pereira said. 'What we'll do with your assistance, Ryker, is to hold a little parley with the chiefs, see whether they remember anything of this capsule.'

Ryker stared out at the Indians now standing directly below the veranda. Irritably he slammed down the blind. 'For God's sake, Pereira, they don't. Tell the Lieutenant he isn't interviewing people on Park Avenue or Piccadilly. If the Indians had seen anything I'd know.'

'Perhaps.' Pereira shrugged. 'Still, I'm under instructions to assist Lieutenant Connolly and it won't do any harm to ask.'

Connolly sat up. 'Having come this far, Captain, I feel I should do two or three forays into the bush.' To Ryker he explained: 'They've recalculated the flight path of the final trajectory, there's a chance he may have come down further along the landing zone. Here, very possibly.'

Shaking his head, Ryker slumped down on to the couch, and drove one fist angrily into the other. 'I suppose this means they'll be landing here at any time with thousands of bulldozers and flamethrowers. Dammit, Lieutenant, if you have to send a man to the Moon, why don't you do it in your own back yard?'

Pereira stood up. 'We'll be gone in a couple of days, Ryker.' He nodded judiciously at Connolly and moved towards the door.

As Connolly climbed to his feet Ryker called out suddenly: 'Lieutenant. You can tell me something I've wondered.' There was an unpleasant downward curve to his mouth, and his tone was belligerent and provocative. 'Why did they really send a man to the Moon?'

Connolly paused. He had remained silent during the conversation, not wanting to antagonize Ryker. The rudeness and complete selfimmersion were pathetic rather than annoying. 'Do you mean the military and political reasons?'

'No, I don't.' Ryker stood up, arms akimbo again, measuring Connolly. 'I mean the real reasons, Lieutenant.'

Connolly gestured vaguely. For some reason formulating a satisfactory answer seemed more difficult than he had expected. 'Well, I suppose you could say it was the natural spirit of exploration.'

Ryker snorted derisively. 'Do you seriously believe that, Lieutenant? "The spirit of exploration!" My God! What a fantastic idea. Pereira doesn't believe that, do you, Captain?'

Before Connolly could reply Pereira took his arm. 'Come on, Lieutenant. This is no time for a metaphysical discussion.' To Ryker he added: 'It doesn't much matter what you and I believe, Ryker. A man went to the Moon and came back. He needs our help.'

Ryker frowned ruefully. 'Poor chap. He must be feeling pretty unhappy by now. Though anyone who gets as far as the Moon and is fool enough to come back deserves what he gets.'

There was a scuffle of feet on the veranda, and as they stepped out into the sunlight a couple of Indians darted away along the jetty, watching Connolly with undiminished interest.

Ryker remained in the doorway, staring listlessly at the clock, but as they were about to climb into the launch he came after them. Now and then glancing over his shoulder at the encroaching semicircle of Indians, he gazed down at Connolly with sardonic contempt. 'Lieutenant,' he called out before they went below. 'Has it occurred to you that if he had landed, Spender might have wanted to stay on here?'

'I doubt it, Ryker,' Connolly said calmly. 'Anyway, there's little chance that Colonel Spender is still alive. What we're interested in finding is the capsule.'

Ryker was about to reply when a faint metallic buzz sounded from the direction of his hut. He looked around sharply, waiting for it to end, and for a moment the whole tableau, composed of the men on the launch, the gaunt outcast on the edge of the jetty and the Indians behind him, was frozen in an absurdly motionless posture. The mechanism of the old alarm clock had obviously been fully wound, and the buzz sounded for thirty seconds, finally ending with a highpitched ping.

Pereira grinned. He glanced at his watch. 'It keeps good time, Ryker.' But Ryker had stalked off back to the hut, scattering the Indians before him.

Connolly watched the group dissolve, then suddenly snapped his fingers. 'You're right, Captain. It certainly does keep good time,' he repeated as they entered the cabin.

Evidently tired by the encounter with Ryker, Pereira slumped down among Connolly's equipment and unbuttoned his tunic. 'Sorry about Ryker, but I warned you. Frankly, Lieutenant, we might as well leave now. There's nothing here. Ryker knows that. However, he's no fool, and he's quite capable of faking all sorts of evidence just to get a retainer out of you. He wouldn't mind if the bulldozers came.'

'I'm not so sure.' Connolly glanced briefly through the porthole. 'Captain, has Ryker got a radio?'

'Of course not. Why?'

'Are you certain?'

'Absolutely. It's the last thing the man would have. Anyway, there's no electrical supply here, and he has no batteries.' He noticed Connolly's intent expression. 'What's on your mind, Lieutenant?'

'You're his only contact? There are no other traders in the area?'

'None. The Indians are too dangerous, and there's nothing to trade. Why do you think Ryker has a radio?'

'He must have. Or something very similar. Captain, just now you remarked on the fact that his old alarm clock kept good time. Does it occur to you to ask how?'

Pereira sat up slowly. 'Lieutenant, you have a valid point.'

'Exactly. I knew there was something odd about those two clocks when they were standing side by side. That type of alarm clock is the cheapest obtainable, notoriously inaccurate. Often they lose two or three minutes in 24 hours. But that clock was telling the right time to within ten seconds. No optical instrument would give him that degree of accuracy.'

Pereira shrugged sceptically. 'But I haven't been here for over four months. And even then he didn't check the time with me.'

'Of course not. He didn't need to. The only possible explanation for such a degree of accuracy is that he's getting a daily time fix, either on a radio or some longrange beacon.'

'Wait a moment, Lieutenant.' Pereira watched the dusk light fall across the jungle. 'It's a remarkable coincidence, but there must be an innocent explanation. Don't jump straight to the conclusion that Ryker has some instrument taken from the missing Moon capsule. Other aircraft have crashed in the forest. And what would be the point? He's not running an airline or railway system. Why should he need to know the time, the exact time, to within ten seconds?'

Connolly tapped the lid of his monitoring case, controlling his growing exasperation at Pereira's reluctance to treat the matter seriously, at his whole permissive attitude of lazy tolerance towards Ryker, the Indians and the forest. Obviously he unconsciously resented Connolly's sharpeyed penetration of this private world.

'Clocks have become his ide ftxe,' Pereira continued. 'Perhaps he's developed an amazing sensitivity to its mechanism. Knowing exactly the right time could be a substitute for the civilization on which he turned his back.' Thoughtfully, Pereira moistened the end of his cheroot. 'But I agree that it's strange. Perhaps a little investigation would be worthwhile after all.'
