“By the way,” interjected Franklin, “is the fence purely electrical?”

  “Oh no. Electric fields control fish pretty well but don’t work satisfactorily on mammals like whales. The fence is largely ultrasonic—a curtain of sound from a chain of generators half a mile below the surface. We can get fine control at the gates by broadcasting specific orders; you can set a whole herd stampeding in any direction you wish by playing back a recording of a whale in distress. But it’s not very often we have to do anything drastic like that; as I said, nowadays they’re too well trained.”

  “I can appreciate that,” said Franklin. “In fact, I heard somewhere that the fence was more for keeping other animals out than for keeping the whales in.”

  “That’s partly true, though we’d still need some kind of control for rounding up our herds at census or slaughtering. Even so, the fence isn’t perfect. There are weak spots where generator fields overlap, and sometimes we have to switch off sections to allow normal fish migration. Then, the really big sharks, or the killer whales, can get through and play hell. The killers are our worst problem; they attack the whales when they are feeding in the Antarctic, and often the herds suffer ten per cent losses. No one will be happy until the killers are wiped out, but no one can think of an economical way of doing it. We can’t patrol the entire ice pack with subs, though when I’ve seen what a killer can do to a whale I’ve often wished we could.”

  There was real feeling—almost passion—in Burley’s voice, and Franklin looked at the warden with surprise. The “whaleboys,” as they had been inevitably christened by a nostalgically minded public in search of heroes, were not supposed to be much inclined either to thought or emotions. Though Franklin knew perfectly well that the tough, uncomplicated characters who stalked tight lipped through the pages of contemporary submarine sagas had very little connection with reality, it was hard to escape from the popular clichés. Don Burley, it was true, was far from tight lipped, but in most other respects he seemed to fit the standard specification very well.

  Franklin wondered how he was going to get on with his new mentor—indeed, with his new job. He still felt no enthusiasm for it; whether that would come, only time would show. It was obviously full of interesting and even fascinating problems and possibilities, and if it would occupy his mind and give him scope for his talents, that was as much as he could hope for. The long nightmare of the last year had destroyed, with so much else, his zest for life—the capacity he had once possessed for throwing himself heart and soul into some project.

  It was difficult to believe that he could ever recapture the enthusiasm that had once taken him so far along paths he could never tread again. As he glanced at Don, who was still talking with the fluent lucidity of a man who knows and loves his job, Franklin felt a sudden and disturbing sense of guilt. Was it fair to Burley to take him away from his work and to turn him, whether he knew it or not, into a cross between a nursemaid and kindergarten teacher? Had Franklin realized that very similar thoughts had already crossed Burley’s mind, his sympathy would have been quenched at once.

  “Time we caught the shuttle to the airport,” said Don, looking at his watch and hastily draining his beer. “The morning flight leaves in thirty minutes. I hope all your stuff’s already been sent on.”

  “The hotel said they’d take care of it.”

  “Well, we can check at the airport. Let’s go.”

  Half an hour later Franklin had a chance to relax again. It was typical of Burley, he soon discovered, to take things easily until the last possible moment and then to explode in a burst of activity. This burst carried them from the quiet bar to the even more efficiently silenced plane. As they took their seats, there was a brief incident that was to puzzle Don a good deal in the weeks that lay ahead.

  “You take the window seat,” he said. “I’ve flown this way dozens of times.”

  He took Franklin’s refusal as ordinary politeness, and started to insist. Not until Franklin had turned down the offer several times, with increasing determination and even signs of annoyance, did Burley realize that his companion’s behavior had nothing to do with common courtesy. It seemed incredible, but Don could have sworn that the other was scared stiff. What sort of man, he wondered blankly, would be terrified of taking a window seat in an ordinary aircraft? All his gloomy premonitions about his new assignment, which had been partly dispelled during their earlier conversation, came crowding back with renewed vigor.

  The city and the sunburned coast dropped below as the lifting jets carried them effortlessly up into the sky. Franklin was reading the paper with a fierce concentration that did not deceive Burley for a moment. He decided to wait for a while, and apply some more tests later in the flight.

  The Glasshouse Mountains—those strangely shaped fangs jutting from the eroded plain—swept swiftly beneath. Then came the little coastal towns, through which the wealth of the immense farm lands of the interior had once passed to the world in the days before agriculture went to sea. And then—only minutes, it seemed, after take-off—the first islands of the Great Barrier Reef appeared like deeper shadows in the blue horizon mists.

  The Sun was shining almost straight into his eyes, but Don’s memory could fill in the details which were lost in the glare from the burning waters. He could see the low, green islands surrounded by their narrow borders of sand and their immensely greater fringes of barely submerged coral. Against each island’s private reef the waves of the Pacific would be marching forever, so that for a thousand miles into the north snowy crescents of foam would break the surface of the sea.

  A century ago—fifty years, even—scarcely a dozen of these hundreds of islands had been inhabited. Now, with the aid of universal air transport, together with cheap power and water-purification plants, both the state and the private citizen had invaded the ancient solitude of the reef. A few fortunate individuals, by means that had never been made perfectly clear, had managed to acquire some of the smaller islands as their personal property. The entertainment and vacation industry had taken over others, and had not always improved on Nature’s handiwork. But the greatest landowner in the reef was undoubtedly the World Food Organization, with its complicated hierarchy of fisheries, marine farms, and research departments, the full extent of which, it was widely believed, no merely human brain could ever comprehend.

  “We’re nearly there,” said Burley. “That’s Lady Musgrave Island we’ve just passed—main generators for the western end of the fence. Capricorn Group under us now—Masthead, One Tree, North-West, Wilson—and Heron in the middle, with all those buildings on it. The big tower is Administration—the aquarium’s by that pool—and look, you can see a couple of subs tied up at that long jetty leading out to the edge of the reef.”

  As he spoke, Don watched Franklin out of the corner of his eye. The other had leaned toward the window as if following his companion’s running commentary, yet Burley could swear that he was not looking at the panorama of reefs and islands spread out below. His face was tense and strained; there was an indrawn, hooded expression in his eyes as if he was forcing himself to see nothing.

  With a mingling of pity and contempt, Don understood the symptoms if not their cause. Franklin was terrified of heights; so much, then, for the theory that he was a spaceman. Then what was he? Whatever the answer, he hardly seemed the sort of person with whom one would wish to share the cramped quarters of a two-man training sub. . . .

  The plane’s shock absorbers touched down on the rectangle of scorched and flattened coral that was the Heron Island landing platform. As he stepped out into the sunlight, blinking in the sudden glare, Franklin seemed to make an abrupt recovery. Don had seen seasick passengers undergo equally swift transformations on their return to dry land. If Franklin is no better as a sailor than an airman, he thought, this crazy assignment won’t last more than a couple of days and I’ll be able to get back to work. Not that Don was in a great rush to return immediately; Heron Island was a pleasant place where
you could enjoy yourself if you knew how to deal with the red tape that always entangled headquarters establishments.

  A light truck whisked them and their belongings along a road beneath an avenue of Pisonia trees whose heavily leafed branches blocked all direct sunlight. The road was less than a quarter of a mile long, but it spanned the little island from the jetties and maintenance plants on the west to the administration buildings on the east. The two halves of the island were partly insulated from each other by a narrow belt of jungle which had been carefully preserved in its virgin state and which, Don remembered sentimentally, was full of interesting tracks and secluded clearings.

  Administration was expecting Mr. Franklin, and had made all the necessary arrangements for him. He had been placed in a kind of privileged limbo, one stage below the permanent staff like Burley, but several stages above the ordinary trainees under instruction. Surprisingly, he had a room of his own—something that even senior members of the bureau could not always expect when they visited the island. This was a great relief to Don, who had been afraid he might have to share quarters with his mysterious charge. Quite apart from any other factors, that would have interfered badly with certain romantic plans of his own.

  He saw Franklin to his small but attractive room on the second floor of the training wing, looking out across the miles of coral which stretched eastward all the way to the horizon. In the courtyard below, a group of trainees, relaxing between classes, was chatting with a second warden instructor whom Don recognized from earlier visits but could not name. It was a pleasant feeling, he mused, going back to school when you already knew all the answers.

  “You should be comfortable here,” he said to Franklin, who was busy unpacking his baggage. “Quite a view, isn’t it?”

  Such poetic ecstasies were normally foreign to Don’s nature, but he could not resist the temptation of seeing how Franklin would react to the leagues of coral-dappled ocean that lay before him. Rather to his disappointment, the reaction was quite conventional; presumably Franklin was not worried by a mere thirty feet of height. He looked out of the window, taking his time and obviously admiring the vista of blues and greens which led the eye out into the endless waters of the Pacific.

  Serve you right, Don told himself—it’s not fair to tease the poor devil. Whatever he’s got, it can’t be fun to live with.

  “I’ll leave you to get settled in,” said Don, backing out through the door. “Lunch will be coming up in half an hour over at the mess—that building we passed on the way in. See you there.”

  Franklin nodded absently as he sorted through his belongings and piled shirts and underclothes on the bed. He wanted to be left alone while he adjusted himself to the new life which, with no particular enthusiasm, he had now accepted as his own.

  Burley had been gone for less than ten minutes when there was a knock on the door and a quiet voice said, “Can I come in?”

  “Who’s there?” asked Franklin, as he tidied up the debris and made his room look presentable.

  “Dr. Myers.”

  The name meant nothing to Franklin, but his face twisted into a wry smile as he thought how appropriate it was that his very first visitor should be a doctor. What kind of a doctor, he thought he could guess.

  Myers was a stocky, pleasantly ugly man in his early forties, with a disconcertingly direct gaze which seemed somewhat at variance with his friendly, affable manner.

  “Sorry to butt in on you when you’ve only just arrived,” he said apologetically. “I had to do it now because I’m flying out to New Caledonia this afternoon and won’t be back for a week. Professor Stevens asked me to look you up and give you his best wishes. If there’s anything you want, just ring my office and we’ll try to fix it for you.”

  Franklin admired the skillful way in which Myers had avoided all the obvious dangers. He did not say—true though it undoubtedly was—“I’ve discussed your case with Professor Stevens.” Nor did he offer direct help; he managed to convey the assumption that Franklin wouldn’t need it and was now quite capable of looking after himself.

  “I appreciate that,” said Franklin sincerely. He felt he was going to like Dr. Myers, and made up his mind not to resent the surveillance he would undoubtedly be getting. “Tell me,” he added, “just what do the people here know about me?”

  “Nothing at all, except that you are to be helped to qualify as a warden as quickly as possible. This isn’t the first time this sort of thing has happened, you know—there have been high-pressure conversion courses before. Still, it’s inevitable that there will be a good deal of curiosity about you; that may be your biggest problem.”

  “Burley is dying of curiosity already.”

  “Mind if I give you some advice?”

  “Of course not—go ahead.”

  “You’ll be working with Don continually. It’s only fair to him, as well as to yourself, to confide in him when you feel you can do so. I’m sure you’ll find him quite understanding. Or if you prefer, I’ll do the explaining.”

  Franklin shook his head, not trusting himself to speak. It was not a matter of logic, for he knew that Myers was talking sense. Sooner or later it would all have to come out, and he might be making matters worse by postponing the inevitable. Yet his hold upon sanity and self-respect was still so precarious that he could not face the prospect of working with men who knew his secret, however sympathetic they might be.

  “Very well. The choice is yours and we’ll respect it. Good luck—and let’s hope all our contacts will be purely social.”

  Long after Myers had gone, Franklin sat on the edge of the bed, staring out across the sea which would be his new domain. He would need the luck that the other had wished him, yet he was beginning to feel a renewed interest in life. It was not merely that people were anxious to help him; he had received more than enough help in the last few months. At last he was beginning to see how he could help himself, and so discover a purpose for his existence.

  Presently he jolted himself out of his daydream and looked at his watch. He was already ten minutes late for lunch, and that was a bad start for his new life. He thought of Don Burley waiting impatiently in the mess and wondering what had happened to him.

  “Coming, teacher,” he said, as he put on his jacket and started out of the room. It was the first time he had made a joke with himself for longer than he could remember.

  CHAPTER

  3

  When Franklin first saw Indra Langenburg she was covered with blood up to her elbows and was busily hacking away at the entrails of a ten-foot tiger shark she had just disemboweled. The huge beast was lying, its pale belly upturned to the Sun, on the sandy beach where Franklin took his morning promenade. A thick chain still led to the hook in its mouth; it had obviously been caught during the night and then left behind by the falling tide.

  Franklin stood for a moment looking at the unusual combination of attractive girl and dead monster, then said thoughtfully: “You know, this is not the sort of thing I like to see before breakfast. Exactly what are you doing?”

  A brown, oval face with very serious eyes looked up at him. The foot-long, razor-sharp knife that was creating such havoc continued to slice expertly through gristle and guts.

  “I’m writing a thesis,” said a voice as serious as the eyes, “on the vitamin content of shark liver. It means catching a lot of sharks; this is my third this week. Would you like some teeth? I’ve got plenty, and they make nice souvenirs.”

  She walked to the head of the beast and inserted her knife in its gaping jaws, which had been propped apart by a block of wood. A quick jerk of her wrist, and an endless necklace of deadly ivory triangles, like a band saw made of bone, started to emerge from the shark’s mouth.

  “No thanks,” said Franklin hastily, hoping she would not be offended. “Please don’t let me interrupt your work.”

  He guessed that she was barely twenty, and was not surprised at meeting an unfamiliar girl on the little island, because the scientists at th
e Research Station did not have much contact with the administrative and training staff.

  “You’re new here, aren’t you?” said the bloodstained biologist, sloshing a huge lump of liver into a bucket with every sign of satisfaction. “I didn’t see you at the last HQ dance.”

  Franklin felt quite cheered by the inquiry. It was so pleasant to meet someone who knew nothing about him, and had not been speculating about his presence here. He felt he could talk freely and without restraint for the first time since landing on Heron Island.

  “Yes—I’ve just come for a special training course. How long have you been here?”

  He was making pointless conversation just for the pleasure of the company, and doubtless she knew it.

  “Oh, about a month,” she said carelessly. There was another slimy, squelching noise from the bucket, which was now nearly full. “I’m on leave here from the University of Miami.”

  “You’re American, then?” Franklin asked. The girl answered solemnly: “No; my ancestors were Dutch, Burmese, and Scottish in about equal proportions. Just to make things a little more complicated, I was born in Japan.”

  Franklin wondered if she was making fun of him, but there was no trace of guile in her expression. She seemed a really nice kid, he thought, but he couldn’t stay here talking all day. He had only forty minutes for breakfast, and his morning class in submarine navigation started at nine.

  He thought no more of the encounter, for he was continually meeting new faces as his circles of acquaintances steadily expanded. The high-pressure course he was taking gave him no time for much social life, and for that he was grateful. His mind was fully occupied once more; it had taken up the load with a smoothness that both surprised and gratified him. Perhaps those who had sent him here knew what they were doing better than he sometimes supposed.

  All the empirical knowledge—the statistics, the factual data, the ins and outs of administration—had been more or less painlessly pumped into Franklin while he was under mild hypnosis. Prolonged question periods, where he was quizzed by a tape recorder that later filled in the right answers, then confirmed that the information had really taken and had not, as sometimes happened, shot straight through the mind leaving no permanent impression.
