  About halfway from the fattest part to the rounded nose a ring of small openings girdled the entire object. And partway back towards the tapering tail, on the top, a three-foot circle showed where an access hatch was located. A ladder led up the side of the cradle to the hatch, which was closed.

  Napoleon Solo stood at the nose of the thing, hands cupped around his face, peering through the porthole into the darkened interior. Illya stood behind him, with a thin dark man in a white lab smock, who was speaking.

  "Some years ago, experiments were being made by medical researchers in the design of blood-pumps for a new design of artificial heart. They were interested in a pump that would not break down under years of constant use. In the course of their tests they discovered that a powerful enough electromagnetic field could affect the blood directly, and move it through tubes without the use of motors or impellers of any kind. Since sea water is electrically quite similar to blood, it was reasoned that the same electromagnetic flux could be used to move it. Stewart Way, of Westinghouse, developed the basic principle just this summer at Santa Barbara."

  Napoleon took his face away from the porthole and wiped the fog of his breath off it with his sleeve. "So that's why the submarine is noiseless. No motor—no moving parts—just an electrical field to pump sea water. That means it's jet-propelled."

  "Like a squid," said Illya. "It takes in sea water and squirts it out again."

  "Exactly," said the inventor. "That is the reason for naming it the Squid. It is a prototype of what will someday be called the Squid class of submarines." He cleared his throat and smiled shyly. "More modest than calling it the Simpson class."

  "Does it squirt ink too?" asked Napoleon.

  "We thought that would be unnecessary. Most undersea combat is carried out by sound rather than by sight."

  "Have you worked out a way of making it invisible to sonar, then?" asked Illya.

  Simpson nodded. "More or less. The propulsion system itself does a great deal to help that."

  Napoleon had wandered around to the pointed end of the submarine, and was looking around, slightly puzzled. "Where's the jet?" he asked. "This end looks solid to me."

  "It is. The jets are up here," said the man in the lab coat, pointing to the ring around the nose of the teardrop.

  Illya looked at them closely. "I thought those were maneuvering jets. They seem to point straight out to the sides."

  "They do," said Simpson. "The electromagnetic impeller drives the water out through this ring at right angles to the direction of travel."

  Napoleon wandered back in time to hear this, and held up his hand for a moment. "Right angles, huh? Then what makes the thing go forward?"

  "It's called the Coanda effect. Don't ask me why it works—I'm an engineer, not a scientist."

  "But you built it; you should understand it."

  "I didn't exactly build it myself—an analogue computer designed the hull from the Coanda equations, the outer hull was built by the construction unit there, the inner pressure hull was built in France, the control systems were prepared by our electronics department, the power system came from General Atomics, and a specialist work crew put them all together here."

  Napoleon pondered this for a moment, then finally asked, "But what do you have to do with the submarine, then?"

  Simpson smiled and shrugged a little. "Well...I'm not sure. All I know is that they didn't build things like this before I came here."

  "Oh," said Napoleon, nodding firmly as though he now understood the whole operation.

  "Anyway," Simpson continued, "basically, the vortex flow created by the jet of water—or air; the design works on airplanes, too—follows the curve of the side. It goes around the bulge, and trails off towards the tail. The flow all comes together at the tip, and pushes the whole thing in the opposite direction. As it starts to move, the flow bends more backward, and the water that flows past is pulled in with the jets, adding to the volume of the flow."

  Illya shook his head. "It seems that would waste a lot of the energy in turbulence. Wouldn't it be simpler and more efficient just to direct the flow out the rear in the traditional manner?"

  "Simplicity is not always the same as efficiency. This particular design is roughly 65% more efficient than the same amount of energy directed out the stern. Dr. Coanda's equations indicate a theoretical limit of approximately twice the efficiency, but we don't have the double efficiency yet.

  "Incidentally, because of the nature of the flow, there is very little turbulence. Instead of wasting energy as in cavitation, as most submarines do, the flow is directed around the vehicle and used for additional propulsive energy. The mass of water that you would ordinarily have to butt your way through is pulled aside by the Coanda jets.

  "This gives you a shell of moving water, inside which your submarine floats. And because of the pressure differential in the flow, as long as you are moving, sonar will be refracted around you rather than bouncing off. You will, in effect, be invisible. Of course, when you slow down or stop, the pressures will equalize and you will reappear. Any more questions?"

  The two U.N.C.L.E. agents looked up at the Coanda Squid. It rested in its cradle like a finless bomb, with the distant blue-white tubes of the overhead fluorescents casting distorted highlights on its bulging surface. Solo remembered something his partner had once said: "Personally, I believe color television to be impossible too. But since it does exist, I will act as if I believed in it."

  He said so. Illya glanced at him, and smiled wryly. The last time he had said that they had been faced with another device, for which no published equations existed, and which was to be used against them—and the rest of the world—by their enemies. This submarine, on the other hand, did have sound, recognized scientific principles behind it. But then, so did color television.

  "Napoleon," he said, "you have simply got to learn to move with the times. So many marvels are constantly being invented, you should learn to accept them."

  "Illya, you know I just have a naturally inquisitive mind. Besides, I like to know how things work before I trust my life to them."

  Illya nodded. "Let's take a look inside."

  They ducked under the cradle, and opened the lower hatch. As they did so, Simpson pointed out the door hinge. "The bearing here is lubricated by the sea water itself," he said. "It reacts with the material to form a smooth film. The greater the pressure, the more efficient the lubrication. One at a time in the airlock, please. You may find it a little crowded with three in the pressure hull, but there will be enough room to see."

  Napoleon followed him, and found a metal tube which appeared to run the whole height of the submarine, to the matching hatch on the top. There were hand grips along the sides, and partway up he found another hatch open on the forward side of the tube. He pulled himself up and through this, and found himself in one side of a sphere. The walls were lined with gear, with three bunks folded up against one side. A small partition shielded a chemical toilet, and next to the bunks a tiny sink and an electric stove made a compact but efficient galley.

  Two control seats, contoured and equipped with safety harnesses, bracketed the inner orifice of the porthole. Both panel layouts seemed identical, with sonar display screens, and matching controls. The sub was apparently maneuvered like an airplane—the wheels and pedals looked the same, and Napoleon recognized rate-of-climb, turn-and-bank, and similar aerial indicators.

  Illya joined them, and after a quick look over the living facilities went straight to the control board. He fitted himself into the righthand seat and tried out the wheel, reached experimentally for the controls, and nodded satisfaction when he found them all comfortably within an arm radius.

  Napoleon climbed up to the other seat, and found it a good fit. Simpson stood between them. "Is everything satisfactory?" he asked.

  "So far," said Illya. "What's our cruising range, and how long is the oxygen supply?"

  "Range of this model is only about a thousand miles. The tanks car
ry air for nine days for two people, six days for three. This is considering eight hours of sleeping per day, no smoking, and no prolonged violent exertion. You will, of course, be completely checked out on the control systems. Any questions before we start?"

  "Yes," said Illya. "The bearings in the doors are lubricated only by sea water; the electromagnetic pumping system will work only on sea water. In other words, this would be useless in fresh water."

  Simpson thought quite a while. "Well..." he said at last, "you're right. It will work perfectly only in one particular environment, even though it is a large environment. But in case of emergency, this gauge here"—he pointed—"reads the salinity of the water. Should it drop towards the red zone, you are coming into an area of fresh water, such as might be caused by the outflow of the mouth of a large river, or an undersea spring. It also trips a buzzer, which can be turned off by this button below the gauge, as warning. Until we develop some more radical departures, you will have to be content with this.

  "Incidentally, should it become necessary, you do have small auxiliary motors to pump the water out the propulsion vents in a more conventional manner, but I'm afraid they do make a small amount of noise. Yes, Mr. Solo?"

  "Ah—I notice the speed indicator has three sets of calibrations on it: knots, kilometers per hour, and miles per day. Why?"

  "Well, I put knots there because this is, after all, a ship of sorts. Kilometers per hour is the international standard measure of speed. And I added miles per hour because that's what I think in. Also, this way you won't have to do conversions in your head."

  "What about me?" asked Illya. "I'm Russian. For me you should have a speed meter calibrated in versts per hour."

  Simpson shrugged. "It's only three cents more for an extra meter face, after all."

  Illya grinned at Napoleon, who shared his little joke, and appreciated the technician's comeback. Without further comment, they went on to discuss the inertial guidance system, which handled most of the navigation for the Squid.

  Their checkout occupied the rest of the day, including a break for lunch, which was prepared from the freeze-dried concentrates in the Squid's stores and cooked up on the electric stove. By the time the clock on the instrument panel read 2200 GMT, which Napoleon's electric wrist watch translated as 5:00 P.M. they had learned a good deal about the internal functioning of the sub.

  The following day they took it out into the East River (which is actually a salt-water tidal estuary rather than a true fresh-water river, which would have interfered with the operation of the Squid) and with Simpson guiding them they cruised submerged through the murky waters of the Upper Bay, and then east past Coney Island and Rockaway Point. Both Napoleon and Illya spent a pleasurable afternoon handling the sub, and leaving and entering the airlock in scuba gear while submerged.

  When they returned, wet and exhausted, to the secret harbor under U.N.C.L.E. Headquarters that evening, a message from Waverly awaited them.

  After briefly refreshing themselves, they reported to the familiar office on the topmost level. Their superior looked up from his work to greet them and inquire about their progress. The necessary amenities disposed of, he continued, "Something new has come up on your current assignment. I have the tape somewhere around here of the latest broadcast from the Monster Wheel—but if you don't understand Esperanto I can tell you roughly what it said:

  "First let me explain that there has recently been some discussion—on a very high level, of course, and terribly secret—of attempting to fire a missile at the Wheel. Sometime this morning, apparently, the Wheel began voice transmission again. Without addressing anyone in particular, it stated in so many words that any missile approaching with twenty kilometers would be considered hostile, and the nation that had launched it would be bombarded with thermonuclear devices from space."

  He paused while his two top agents looked at each other, and raised two pairs of eyebrows slightly. Then he continued, a slight tone of annoyance creeping into his voice. "They concluded by saying that they had made no threats to any nation, and had broken no laws, but they would defend themselves if attacked. And of course as far as that goes they are correct. There's no law in the world against launching a space station without a license. Nor is there any that says you must identify your space stations. But every one of the governments represented by the United Network Command is biting its collective fingernails and urging me to do something about this menace in the sky."

  He snorted and leaned back in his chair. "You understand my position. All I can do is make the situation clear to you, and urge your greatest efficiency and most careful work. And this is unnecessary, because you work at peak efficiency most of the time anyway. If you didn't, you wouldn't be in the positions you now occupy."

  "Exactly," said Napoleon. "We'd be sitting behind a nice safe desk somewhere."

  Waverly's face wrinkled into a wry smile. "There are times, Mr. Solo, when I would gladly trade this nice safe desk of mine for a good simple field assignment. Out there, at least, you are allowed to shoot back when you are attacked. Here there is no protection, and no retaliation." He shook his head. "But to return to the subject. I would like to accelerate the operation by a day, if possible. How would you feel about taking off for Ceylon tomorrow, instead of Friday? It will give you a day less to practice with the submarine, but Simpson's reports on your work have been most satisfactory. How do you feel?"

  They nodded simultaneously, and Napoleon spoke. "If you have the aerial survey maps, and the underwater contour maps we'll need, we can take off any time."

  "They are ready, and will be here in my office for you tomorrow morning. You can spend the day making your final preparations. The jet leaves Kennedy International at four P.M. It's not a regular commercial flight, but a cargo plane. The submarine will accompany you disguised as several automobiles."

  "I suppose it's too late to make one change in the submarine," said Illya slowly. "Not a major one—more a design revision than anything else."

  They looked at him questioningly.

  "Gray is such a drab color. How much more appropriate if it could be painted yellow."

  "Appropriate? And why yellow?"

  "Oh, never mind," said Illya. "It was just an idea...."

  Chapter 10: "Island Ho!"

  After lunch the Captain conducted Napoleon Solo and Illya Kuryakin below decks and unlocked the doors in the "D" hold. The harsh incandescents overhead cast black shadows and sharp highlights around the small chamber, and left a pool of inky blackness under the Squid, which hung in a double canvas sling a few feet above the floor.

  The ship in which they had left Colombo some three days ago was a disreputable-looking freighter, flying the Liberian flag, but owned and operated, sometimes at a profit, by the United Network Command for Law and Enforcement. It usually worked as a real freighter, but was maintained as a cover for a number of unusual operations, for which it was specially outfitted. "D" hold was only one of the many special features of the ship. Only her captain was privy to all the surprises contained by her hull, and his U.N.C.L.E. rank was not much lower than Solo's own.

  Down in the damp darkness of the hold, the mini-sub swung gently in her canvas cradle, awaiting the kiss of the salt water that would bring her to life. Inside her dull gray body rested maps, supplies and equipment that would direct and sustain two valuable men for an indefinite period of time—underwater, and ashore in a hostile land.

  The ship's engines were idling now, and the time had come for parting. Napoleon and Illya slipped through the hatch in the underside of the Squid, with a last look around at the dim interior of the hold—the smell of rust, the patches of moss on the walls, and the bearded captain standing near the door, awaiting their signal.

  And then they were inside. The slight pressure change on his eardrums told Napoleon that the outer hatch had been sealed, and a moment later Illya's blond head appeared in the airlock.

  "Welcome aboard, Captain Kuryakin," he said formally.
r />   "Thank you, Captain Solo," said the Russian agent, as he slipped into his padded control seat and fastened the safety straps.

  At the same time, Napoleon lifted a small microphone from a clip below the board, thumbed the button on the side, and said, "Hello, Mother Ship. Squid is ready to go."

  A speaker next to the mike-slip hissed to life. "Hello, Squid. Your signal clear. All set." The lights outside the little sub blinked out, and a moment later, as Illya touched a button, their own headlights blazed to life. "'D' hold sealed," said the speaker. "Open 'er up."

  Faintly through the double hull of the submarine Napoleon could hear a low rumble of heavy machinery. Leaning forward, his head next to Illya's, he peered out through their little porthole into the vast hollow of the hold.

  The floor was bubbling up, blue and sparkling, beneath them. The deck plates were drawing back into the bulkheads, and the sea, carrying the hot equatorial afternoon sunlight around the bulk of the ship, surged up under their plastic craft. It stopped a few feet below the porthole, and the speaker hissed again.

  "Pressure in 'D' hold equalized. Bleed air."

  Smoothly now the level began to rise. Illya turned off their headlights again as a bright line of surface crawled upwards across the window, and the Squid began to quiver as the water took her weight. She rocked slightly as she floated free of the cradle sling, and meters sprang to life as Napoleon closed the switches that began the powerful electromotive forces driving sea water out through the Coanda ring. The two agents felt a gentle surge as the Squid slipped out of her sling, and Napoleon slid a lever slowly forward. Tanks of ballast began to flood, and the walls of the hold seemed to move upward around them. Then the hull of the ship was suddenly floating above them, and the blue-green light flooded into their pressure sphere. Napoleon thumbed the microphone button again.
