There was another man in his drawing-room, and a young woman. Jack Tracy was a young-middle-aged man, blond, with a pock-marked face and a general air of capable toughness about him. The toughness and capability were undoubtedly there -- they had to be for any man to be the general manager of Smith's vast chain of newspapers and magazines.

Maria Schneider, with her slightly dusky skin and brown eyes, could have been South American, Southern Mediterranean or Middle Eastern. Her hair was the colour of a raven. Whatever her nationality she was indisputably beautiful with a rather inscrutable face but invariably watchful penetrating eyes. She didn't look kind or sensitive but was both. She looked intelligent and had to be: when not doubling -- as rumour had it - as Smith's mistress she was his private and confidential secretary and it was no rumour that she was remarkably skilled in her official capacity.

The phone rang. Maria answered, told the caller to hold and brought the phone on its extension cord across to Smith's armchair. He took the phone and listened briefly.

'Ah, Hiller!' Smith, unusually for him, leant forward in his armchair.

There was antic.i.p.ation in both his voice and posture. 'You have, I trust, some encouraging news for me. You have? Good, good, good.

Proceed.'

Smith listened in silence to what Hiller had to say, the expression on his face gradually changing from pleasure to the near beatific. It was a measure of the man's self-control that, although apparently in a near transport of excitement, he refrained from either exclamations, questions or interruptions and heard Hiller through in silence to the end.

'Excellent!' Smith was positively jubilant. 'Truly excellent. Frederik, you have just made me the happiest man in Brazil.' Although Hiller claimed to be called Edward, his true given name would have appeared to be otherwise. 'Nor, I a.s.sure you, will you have cause to regret this day. My car will await you and your friends at the airport at eleven a.m.' He replaced the receiver. 'I said I could wait forever. Forever is today.'

Moments pa.s.sed while he gized sightlessly into the flames. Tracy and Maria looked at each other without expression. Smith sighed, gradually bestirred himself, leaned back into his armchair, reached into his pocket, brought out a gold coin, and examined it intently.

'My talisman,' he said. He still didn't appear to be quite with them.

'Thirty long years I've had it and I've looked at it every day in those thirty years. Hiller has seen this very coin. He says the ones this man Hamilton has are identical in every way. Hiller is not a man to make mistakes so this can mean only one thing. Hamilton has found what can only be the foot of the rainbow.'

Tracy said: 'And at the far end of the rainbow lies a pot of gold?'

Smith looked at him without really seeing him. 'Who cares about the gold?'

There was a long and, for Tracy and Maria, rather uncomfortable silence.

Smith sighed again and replaced the coin in his pocket.

'Another thing,' Smith went on. 'Hamilton appears to have stumbled across some sort of an El Dorado.'

'It seems less and less likely that Hamilton is the kind of man to stumble across anything,' Maria said. 'He's a hunter, a seeker - but never a stumbler. He has sources of information denied other so-called civilised people, especially among the tribes not yet cla.s.sified as pacified. He starts off with some sort of clue that points him in the right direction then starts quartering the ground, narrowing the area of search until he finally pinpoints what he's after. The element of chance doesn't enter into that man's calculations.'

'You might be right, my dear,' Smith said. 'In fact you're almost certainly right. Anyway, what matters is that Hiller says that Hamilton seems to have located some diamond h.o.a.rd.'

Maria said: 'Part of the war loot?'

'Overseas investments, my dear, overseas investments. Never war loot. In this case, however, no. They are uncut -- rough-cut, rather - Brazilian diamonds. And Hiller is an expert on diamonds -G.o.d knows he's stolen enough in his lifetime. Anyway, it appears that Hamilton has fallen for Hiller's story, hook, line and sinker - in Hiller's rather uninspired phrase. Two birds with one stone -- he's found both the European gold and the Brazilian diamonds. Looks as if this is going to be even easier than we thought.'

Tracy looked vaguely troubled. 'He hasn't the reputation for being an easy man.'

'Among the tribes of the Mato Grosso, agreed,' Smith said. He smiled as if antic.i.p.ating some future pleasure. 'But he's going to find himself in a different kind of jungle here.'

'Maybe you overlook one thing,' Maria said soberly. 'Maybe you're overlooking the fact that you've got to go back into that jungle with him.'

Hiller, in his room in the Hotel Negresco, was studying a gold coin which he held in his hand when he was disturbed by an erratic knock on the door. He pulled out a gun, held it behind his back, crossed to the door and opened it.

Hiller put his gun away: the precaution had been unnecessary. Serrano, both hands clutching the back of his neck, swayed dizzily and practically fell into the room.

'Brandy!' Serrano's voice was a strangled croak.

'What the h.e.l.l's happened to you?'

'Brandy!'

'Brandy coming up,' Hiller said resignedly. He gave a generous double to Serrano who downed it in a single gulp. He had just finished his third brandy and was pouring out his tale of woe when another sharp rat-tat-tat came on the door, this knocking far from erratic. Again Hiller took his precautionary measures and again they proved unnecessary. The Hamilton who stood in the doorway was scarcely recognisable as the Hamilton of two hours previously. Two hours in the Hotel de Paris's grandiloquently named Presidential suite -- no president had ever or would ever stay there, but it had the only bath in the hotel not corroded with rust -- had transformed him. He had bathed and was clean-shaven! He wore a fresh set of khaki drills, a fresh khaki shirt without a rent in sight and even a pair of gleaming new shoes.

Hiller glanced at his watch. 'Two hours precisely. You are very punctual.'

The politeness of princes.' Hamilton entered the room and caught sight of Serrano who was busy pouring himself another large brandy. By this time it was difficult to judge whether he was suffering the more from the effects of the blow or the brandy. Holding the gla.s.s in one rather unsteady hand and ma.s.saging the back of his neck with the other, he continued the restorative process without seeming to notice Hamilton.

Hamilton said: 'Who's this character?'

'Serrano,' Hiller said. 'An old friend.' It would have been impossible to guess from Hiller's casual off-handedness that he'd met Serrano for the first time only that evening. 'Don't worry. He can be trusted.'

'Delighted to hear it,' Hamilton said. He couldn't remember the month or the year when he last trusted anybody. 'Makes a welcome change in this day and age.' He peered at Serrano with the air of a concerned and kindly healer. 'Looks to me as if he's coming down with something.'

'He's been down,' Hiller said. 'Mugged.' He was observing Hamilton closely but could well have spared himself the trouble.

'Mugged?' Hamilton looked mildly astonished. 'He was walking the streets this time of night?'

'Yes.'

'And alone?'

'Yes,' Hiller said and added in what he probably regarded as a rather pointed fashion: 'You walk alone at night.'

'I know Romono,' Hamilton said. 'Much more importantly, Romono knows me.' He looked pityingly at Serrano. 'I'll bet you weren't even walking in the middle of the road - and I'll bet you're that much lighter by the weight of your wallet.'

Serrano nodded, scowled, said nothing and got back to his self-medication.

'Life's a great teacher,' Hamilton said absently. 'But it beats me how a citizen of Romono could be so d.a.m.ned stupid. Okay, Hiller, when do we leave?'

Hiller had already turned towards a gla.s.s-fronted wall cupboard.

'Scotch?' he said. 'No firewater. Guaranteed.' He showed Hamilton a famous proprietary brand of Scotch with the seal, unbroken.

'Thanks.'

Hiller's gesture had not been motivated by an undiluted spirit of hospitality. He had turned his back on Hamilton to conceal what he knew must have been a momentary flash of triumph in his face; moreover, this was definitely a moment for celebration. Back in the bar of the Hotel de Paris he had been sure that he had his fish hooked: now he had it gaffed and landed.

'Cheers,' he said. 'We leave at first light tomorrow.'

'How do we go?'

'Bush plane to Cuiaba.' He paused then added apologetically: 'Rickety old bus of cardboard and wire but it's never come down yet. After that, Smith's private jet. That's something else again. It will be waiting for us at Cuiaba.'

'How do you know?'

Hiller nodded towards the phone. 'Carrier pigeon,'

'Pretty sure of yourself, weren't you?'

'Not really. We like to arrange things in advance. I just go on probabilities.' Hiller shrugged. 'One call to fix things, then another call to cancel. Then from Cuiaba to Smith's private airfield in Brasilia.' He nodded towards Serrano. 'He's coming with us.'

'Why?'

'Why ever not?' Hiller even managed to look puzzled. 'My friend. Smith's employee. Good jungle man.'

'Always wanted to meet one of those.' Hamilton looked consideringly at Serrano. 'One can only hope that he's a little bit more alert in the depths of the Mato Grosso than he is in the alleys of Romono.'

Serrano had nothing to say to this but he was, clearly, thinking: prudently he refrained from voicing his thoughts.

Smith, it would seem, was both a considerate man and one who thought of everything. Not only had he stocked his Lear with a splendid variety of liquor, liqueurs, wines and beers, he'd even provided an exceptionally attractive stewardess to serve them up. All three men -- Hamilton, Hiller and Serrano - had long, cold drinks in their hands. Hamilton gazed happily at the green immensity of the Amazonian rain forest pa.s.sing by beneath them.

'This fairly beats hacking your way through that lot down there,' he said. He looked round the cabin of the luxuriously appointed jet. 'But this is for the carriage trade. What transport is Smith thinking of using when we make our trip into the Mato Grosso?'

'No idea,' Hiller said. 'Matters like that, Smith doesn't consult me.

He's got his own advisers for that. You'll be seeing him in a couple of hours. I suppose he'll tell you then.'

'I don't think you quite understand,' Hamilton said in an almost gently explanatory tone. 'I only asked what transport he was thinking of using.

Any decisions he and his experts have made are not really very relevant.'

Hiller looked at him in slow disbelief. ' You are going to tell him what we're to use?'

Hamilton beckoned the stewardess, smiled and handed over his gla.s.s for a refill. 'Nothing like savouring the good life -- while it lasts.' He turned to Hiller. 'Yes, that's the idea.'

'I can see,' Hiller said heavily, 'that you and Smith are going to get along just fine.'

'Oh, I hope so, I hope so. You said we'd be seeing him In two hours.

Could you make it three?' He looked disparagingly at his wrinkled khaki drills. 'These look well enough in Romono, but I have to see a tailor before I go calling on multimillionaires. You say we're being met when we arrive. You think you can drop me off at the Grand?'

'Jesus!' Hiller was clearly taken aback. 'The Grand -- and a tailor.

That's expensive. How come? Last night in the bar you said you had no money.'

'I came into some later on.'

Hiller and Serrano exchanged very peculiar looks. Hamilton continued to gaze placidly out of the window.

As promised a car met them at the private airport in Brasilia. 'Car' was really too mundane a word to describe it. It was an enormous maroon Rolls-Royce, big enough, one would have thought, to accommodate a football team. In the back it had television, a bar and even an ice-maker. Up front -very far up front -- were two uniformed men in dark green livery. One drove the car: the other's main function in life appeared to be opening doors when the back seat -- seats -- pa.s.sengers entered or left. The engine, predictably, was soundless. If it were part of Smith's pattern to awe visitors he most certainly succeeded in the case of Serrano.

Hamilton appeared quite unimpressed, possibly because he was too busy inspecting the bar; Smith had somehow overlooked providing a stewardess for the rear of the Rolls.

They drove through the wide avenues of that futuristic city and pulled up outside the Grand Hotel. Hamilton dismounted -- the door having magically been opened for him, of course - and pa.s.sed swiftly through the revolving door. Once inside, he looked out through the gla.s.sed-in porch. The Rolls, already more than a hundred yards away, was turning a corner to the left. Hamilton waited until it had disappeared from sight, left by the revolving door by which he had entered and started to walk briskly back in the direction from which they had come. He gave the impression of one who knew the city, and he did: he knew Brasilia very well indeed.

Five minutes after dropping Hamilton the Rolls, pulled up outside a photographer's shop. Hiller went inside, approached a smiling and affable a.s.sistant and handed over the film that had been taken from Hamilton.

'Have this developed and sent to Mr Joshua Smith, Haydn Villa.' There was no need for Hiller to add the word 'immediately'. Smith's name guaranteed immediacy. Hiller went on: 'No copy is to be made of this film and neither the person who develops it nor any other member of your staff is ever to discuss it. I hope that is clearly understood.' 'Yes, sir. Of course, sir.' The smile and the affability had vanished to be replaced by total obsequiousness. 'Speed and secrecy. Those are guaranteed, sir.'

'And a perfect print?'

'If the negative is perfect so will the print be.' Hiller couldn't think of how else he could threaten the now thoroughly apprehensive a.s.sistant so he nodded and left.

Another ten minutes later and Hiller and Serrano were in the drawing-room of the Villa Haydn. Serrano was seated, as were Tracy, Maria and a fourth and as yet unidentified man. Smith talked somewhat apart with Hiller -- 'somewhat apart' in that huge drawing-room meant a considerable distance -- glancing occasionally in Serrano's direction.

Hiller said: 'Of course, I can't vouch for him. But he knows an awful lot that we don't and I can always see to it that he'll make no trouble.

Come to that, so would Hamilton. Hamilton has a rough way of dealing with people who step out of line.' Hiller went on to tell the sad tale of Serrano's mugging.

'Well, if you say so, Hiller.' Smith sounded doubtful and if there was one thing Smith didn't like it was being doubtful about anything. 'You certainly haven't let me down so far.' He paused. 'But your friend Serrano seems to have no history, no past.'

'Neither have most men in the Mato Grosso. Usually for the 'simple reason that they have too much of a past. But he knows his jungle -- and he knows more Indian dialects than any man except maybe Hamilton.

Certainly more than any man in the Indian Protection Service.'

'All right.' Smith had made up his mind and seemed relieved for that.

'And he's been close to the Lost City. Could be a useful back-up man.'

Hiller nodded towards the unidentified person, a tall, very heavily built, darkly handsome man in his mid-thirties.

'Who's that, Mr Smith?'

'Heffner. My chief staff photographer.'

Hiller said: 'Mr Smith!'

'Hamilton would think it extremely strange if I didn't take a staff photographer along on this historic trip,' Smith said reasonably. He smiled slightly. 'I will confess, though, that he can use one or two instruments other than his cameras.'

' I'il bet he can.' Hiller looked at Heffner with even closer interest.

'Another with or without a past?'

Smith smiled again but made no answer. A phone rang. Tracy, who was nearest to it, picked it up, listened briefly and replaced the receiver.

'Well, well. Surprise, surprise. The Grand Hotel has no one registered there under the name of Hamilton. Not only that, no member of the staff can recall ever seeing a man answering to the description.'

Hamilton, at that moment, was in a lavishly furnished suite in the Hotel Imperial.

Ramon and Navarro, seated on a couch, were admiring Hamilton, who was admiring himself in front of a full-length mirror.

'Always did fancy myself in a fawn seersucker,' Hamilton said complacently. 'Don't you agree? This should knock Smith for six.'

'I don't know about Smith,' Ramon said, 'but in that outfit you'd terrify even the Muscias. So no trouble with getting the invitation?'
