She had almost reached them before she realized that she had already met the smaller man. For his part, Franklin was looking at her with a slightly baffled, “Haven’t we seen each other before?” expression.
“Hello,” she said, coming to a standstill beside them. “Remember me? I’m the girl who collects sharks.”
Franklin smiled and answered: “Of course I remember: It still turns my stomach sometimes. I hope you found plenty of vitamins.”
Yet strangely enough, the puzzled expression — so typical of a man straining after memories that will not come — still lingered in his eyes. It made him look lost and more than a little worried, and Indra found herself reacting with sympathy, which was disconcerting. She had already had several narrow escapes from emotional entanglements on the island, and she reminded herself firmly of her resolution: “Not until after I’ve got my master’s degree…”
“So you know each other,” said Don plaintively. “You might introduce me.” Don, Indra decided, was perfectly safe. He would start to flirt with her at once, like any warden worthy of his calling. She did not mind that in the least; though big leonine blonds were not precisely her type, it was always flattering to feel that one was causing a stir, and she knew that there was no risk of any serious attachment here. With Franklin, however, she felt much less sure of herself.
They chattered pleasantly enough, with a few bantering undertones, while they stood watching the big fish and porpoises circling slowly in the oval pool. The lab’s main tank was really an artificial lagoon, filled and emptied twice a day by the tides, with a little assistance from a pumping plant. Wire-mesh barriers divided it into various sections through which mutually incompatible exhibits stared hungrily at each other; a small tiger shark, with the inevitable sucker fish glued to its back, kept patrolling its underwater cage, unable to take its eyes off the succulent pompano parading just outside. In some enclosures, however, surprising partnerships had developed. Brilliantly colored crayfish, looking like overgrown shrimps that had been sprayed with paint guns, crawled a few inches away from the incessantly gaping jaws of a huge and hideous moray eel. A school of fingerlings, like sardines that had escaped from their tin, cruised past the nose of a quarter-ton grouper that could have swallowed them all at one gulp.
It was a peaceful little world, so different from the battlefield of the reef. But if the lab staff ever failed to make the normal feeding arrangements, this harmony would quickly vanish and in a few hours the population of the pool would start a catastrophic decline.
Don did most of the talking; he appeared to have quite forgotten that he had brought Franklin here to see some of the whale-recognition films in the lab’s extensive library. He was clearly trying to impress Indra, and quite unaware of the fact that she saw through him completely. Franklin, on the other hand, obviously saw both sides of the game and was mildly entertained by it. Once, Indra caught his eye, when Don was holding forth about the life and hard times of the average warden, and they exchanged the smiles of two people who share the same amusing secret. And at that moment Indra decided that, after all, her degree might not be the most important thing in the world. She was still determined not to get herself involved — but she had to learn more about Franklin. What was his first name? Walter. It was not one of her favorites, but it would do.
In his calm confidence that he was laying waste another susceptible female heart, Don was completely unaware of the undercurrents of emotion that were sweeping around him yet leaving him utterly untouched. When he suddenly realized that they were twenty minutes late for their appointment in the projection room, he pretended to blame Franklin, who accepted the reproof in a good-natured but slightly absent-minded manner. For the rest of the morning, indeed, Franklin was rather far away from his studies; but Don noticed nothing at all.
The first part of the course was now virtually completed; Franklin had learned the basic mechanics of the warden’s profession and now needed the experience that only time would give. In almost every respect, he had exceeded Burley’s hopes, partly because of his original scientific training, partly because of his innate intelligence. Yet there was more to it even than this; Franklin had a drive and determination that was sometimes frightening. It was as if success in this course was a matter of life and death to him. True, he had been slow in starting; for the first few days he had been listless and seemingly almost uninterested in his new career. Then he had come to life, as he awoke to the wonder and challenge — the endless opportunity — of the element he was attempting to master. Though Don was not much given to such fancies, it seemed to him that Franklin was like a man awakening from a long and troubled sleep.
The real test had been when they had first gone underwater with the torpedoes. Franklin might never use a torp again — except for amusement — during his entire career; they were purely shallow-water units designed for very short-range work, and as a warden, Franklin would spend all his operational time snug and dry behind the protective walls of a sub. But unless a man was at ease and confident — though not overconfident — when he was actually immersed in water, the service had no use for him, however qualified he might be in other respects.
Franklin had also passed, with a satisfactory safety margin, the decompression, CO2, and nitrogen narcosis tests. Burley had put him in the station’s “torture chamber,” where the doctors slowly increased the air pressure and took him down on a simulated dive. He had been perfectly normal down to 150 feet; thereafter his mental reactions became sluggish and failed to do simple sums correctly when they were given to him over the intercom. At 300 feet he appeared to be mildly drunk and started cracking jokes which reduced him to tears of helpless laughter but which were quite unfunny to those outside — and embarrassingly so to Franklin himself when they played them back to him later. Three hundred and fifty feet down he still appeared to be conscious but refused to react to Don’s voice, even when it started shouting outrageous insults. And at 400 feet he passed out completely, and they brought him slowly back to normal.
Though he would never have occasion to use them, he was also tested with the special breathing mixtures which enable a man to remain conscious and active at far greater depths. When he did any deep dives, he would not be wearing underwater breathing gear but would be sitting comfortably inside a sub breathing normal air at normal pressure. But a warden had to be a Jack of all underwater trades, and never knew what equipment he might have to use in an emergency.
Burley was no longer scared — as he had once been — at the thought of sharing a two-man training sub with Franklin. Despite the other’s underlying reticence and the mystery which still surrounded him, they were partners now and knew how to work together. They had not yet become friends, but had reached a state which might be defined as one of tolerant respect.
On their first sub run, they kept to the shallow waters between the Great Barrier Reef and the mainland, while Franklin familiarized himself with the control, and above all with the navigational instruments. If you could run a sub here, said Don, in this labyrinth of reefs and islands, you could run it anywhere. Apart from trying to charge Masthead Island at sixty knots, Franklin performed quite creditably. His fingers began to move over the complex control board with a careful precision which, Don knew, would soon develop into automatic skill. His scanning of the many meters and display screens would soon be unconscious, so that he would not even be aware that he saw them — until something called for his attention.
