And with this thought there came the first flicker of apprehension. Almost every week, old friends and old enemies came to this remote spot, to exchange news and to reminisce about the past. He welcomed such visits, for they gave a continuing pattern to his life. Yet always he knew, to a high degree of accuracy, the purpose of the meeting, and the ground that would be covered. But as far as Rajasinghe was aware, he and Morgan had no interests in common, beyond those of any men in this day and age. They had never met, or had any prior communication; indeed, he had barely recognised Morgan's name. Still more unusual was the fact that the engineer had asked him to keep this meeting confidential.

Though Rajasinghe had complied, it was with a feeling of resentment. There was no need, any more, for secrecy in his peaceful life; the very last thing he wanted now was for some important mystery to impinge upon his well-ordered existence. He had finished with Security for ever; ten years ago – or was it even longer? – his personal guards had been removed at his own request. Yet what upset him most was not the mild secrecy, but his own total bewilderment. The Chief Engineer (Land) of the Terran Construction Corporation was not going to travel thousands of kilometres merely to ask for his autograph, or to express the usual tourist platitudes. He must have come here for some specific purpose – and, try as he might, Rajasinghe was unable to imagine it.

Even in his days as a public servant, Rajasinghe had never had occasion to deal with TCC; its three divisions – Land, Sea, Space – huge though they were, made perhaps the least news of all the World Federation's specialised bodies. Only when there was some resounding technical failure, or a head-on collision with an environmental or historical group, did TCC emerge from the shadows. The last confrontation of this kind had involved the Antarctic Pipeline – that miracle of twenty-first-century engineering, built to pump fluidised coal from the vast polar deposits to the power plants and factories of the world. In a mood of ecological euphoria, TCC had proposed demolishing the last remaining section of the pipeline and restoring the land to the penguins. Instantly there had been cries of protest from the industrial archaeologists, outraged at such vandalism, and from the naturalists, who pointed out that the penguins simply loved the abandoned pipeline. It had provided housing of a standard they had never before enjoyed, and thus contributed to a population explosion that the killer whales could barely handle. So TCC had surrendered without a fight.

Rajasinghe did not know if Morgan had been associated with this minor dйbacle. It hardly mattered, since his name was now linked with TCC's greatest triumph.

The Ultimate Bridge, it had been christened; and perhaps with justice. Rajasinghe had watched, with half the world, when the final section was lifted gently skywards by the Graf Zeppelin – itself one of the marvels of the age. All the airship's luxurious fittings had been removed to save weight; the famous swimming pool had been drained, and the reactors were pumping their excess heat into the gas-bags to give extra lift. It was the first time that a dead-weight of more than a thousand tons had even been hoisted three kilometres straight up into the sky, and everything – doubtless to the disappointment of millions – had gone without a hitch.

No ship would ever again pass the Pillars of Hercules without saluting the mightiest bridge that man had ever built – or, in all probability, would ever build. The twin towers at the junction of Mediterranean and Atlantic were themselves the tallest structures in the world, and faced each other across fifteen kilometres of space – empty, save for the incredible, delicate arch of the Gibraltar Bridge. It would be a privilege to meet the man who had conceived it; even though he was an hour late.

“My apologies, Ambassador,” said Morgan as he climbed out of the trike. “I hope the delay hasn't inconvenienced you.”

“Not at all; my time is my own. You've eaten, I hope?”

“Yes – when they cancelled my Rome connexion, at least they gave me an excellent lunch.”

“Probably better than you'd get at the Hotel Yakkagala. I've arranged a room for the night – it's only a kilometre from here. I'm afraid we'll have to postpone our discussion until breakfast.”

Morgan looked disappointed, but gave a shrug of acquiescence.

“Well, I've plenty of work to keep me busy. I assume that the hotel has full executive facilities – or at least a standard terminal.”

Rajasinghe laughed. «I wouldn't guarantee anything much more sophisticated than a telephone. But I have a better suggestion. In just over half-an-hour, I'm taking some friends to the Rock. There's a son-et-lumiиre performance that I strongly recommend, and you're very welcome to join us.»

He could tell that Morgan was hesitating, as he tried to think of a polite excuse.

“That's very kind of you, but I really must contact my office…” “You can use my console. I can promise you – you'll find the show fascinating, and it only lasts an hour. Oh, I'd forgotten – you don't want anyone to know you're here. Well, I'll introduce you as Doctor Smith from the University of Tasmania. I'm sure my friends won't recognise you.”

Rajasinghe had no intention of offending his visitor, but there was no mistaking Morgan's brief flash of irritation. The ex-diplomat's instincts automatically came into play; he filed the reaction for future reference.

“I'm sure they won't,” Morgan said, and Rajasinghe noted the unmistakable tone of bitterness in his voice. “Doctor Smith would be fine. And now – if I might use your console.”

Interesting, thought Rajasinghe as he led his guest into the villa, but probably not important. Provisional hypothesis: Morgan was a frustrated, perhaps even a disappointed man. It was hard to see why, since he was one of the leaders of his profession. What more could he want? There was one obvious answer; Rajasinghe knew the symptoms well, if only because in his case the disease had long since burned itself out

“Fame is the spur,” he recited in the silence of his thoughts. How did the rest of it go? “That last infirmity of noble mind… To scorn delights, and live laborious days.”

Yes, that might explain the discontent his still-sensitive antennae had detected. And he suddenly recalled that the immense rainbow linking Europe and Africa was almost invariably called the Bridge occasionally the Gibraltar Bridge… but never Morgan's Bridge.

Well, Rajasinghe thought to himself, if you're looking for fame, Dr. Morgan, you won't find it here. Then why in the name of a thousand yakkas have you come to quiet little Taprobane?

For days, elephants and slaves had toiled in the cruel sun, hauling the endless chains of buckets up the face of the cliff. “Is it ready?” the King had asked, time and again. “No, Majesty,” the master craftsman had answered, “the tank is not yet full. But tomorrow, perhaps…”

Tomorrow had come at last, and now the whole court was gathered in the Pleasure Gardens, beneath awnings of brightly coloured cloth. The King himself was cooled by large fans, waved by supplicants who had bribed the chamberlain for this risky privilege. It was an honour which might lead to riches, or to death.

All eyes were on the face of the Rock, and the tiny figures moving upon its summit. A flag fluttered; far below, a horn sounded briefly. At the base of the cliff workmen frantically manipulated levers, hauled on ropes. Yet for a long time nothing happened.

A frown began to spread across the face of the King, and the whole court trembled. Even the waving fans lost momentum for a few seconds, only to speed up again as the wielders recalled the hazards of their task. Then a great shout came from the workers at the foot of Yakkagala-a cry of joy and triumph that swept steadily closer as it was taken up along the flower-lined paths. And with it came another sound, one not so loud, yet giving the impression of irresistible, pent-up forces, rushing towards their goal.
