"It is approximately two hundred and fifty feet across. The tubular body of the satellite is therefore thirty or forty feet in diameter." He paused.

Napoleon looked puzzled. "I would have thought we would have heard about something that big. I take it that it isn't ours?"

"Not only that, Mr. Solo. Apparently it isn't anyone's. Neither the Russians nor the British nor the French have claimed it. The best guess so far is that it may be a Chinese effort, using Russian equipment, but they have made no statement to that effect so far, and this remains at best a doubtful hypothesis."

"It should have taken some time to build something that large," said Illya thoughtfully. "It would have to have been constructed in orbit—it simply is not structurally capable of standing the stresses of a rocket launching."

Napoleon cleared his throat tentatively. "Ah—has anyone thought that it might not have been launched from the Earth?"

Illya started to say, "Oh, really, Napoleon!" but he was cut off.

"Extraterrestrial origin?" Waverly nodded. "The idea has already been offered. It was under serious consideration, in fact, until the nature of the transmission from the Wheel changed, a day and a half ago."

"Changed? How?"

"Before it had merely been sending coded telemetric signals. Now..." Their superior touched another button, and a concealed speaker came to life. They heard the familiar twittering of telemetry, and then a voice began—definitely a human voice. It was male, baritone, and young.

"Saluton, Tera Komandejo," it said. "Jen Spaci-Stacio Unu, sendante sian unuan raporton reen al la Tero. La sipanaro alvenis sur la transport-sipoj sendifekte, kaj ciuj aparatoj ci tie funkcias bonege."

The voice continued in the same language. Suzie looked puzzled. "That sounds like Italian," she said, "but I don't understand it."

"It's Esperanto," said Illya. "An artificial language—the best-known of many. It's spoken and understood all over the world."

"What's he saying?"

"He started by identifying himself as 'Space-Station One,' and this as the first report to Earth, saying the crew had arrived on the shuttle ships safely, and all systems there were functioning perfectly. Now he's talking about the view. He says they're crossing the dawn line over Nepal, and only the peaks of the Himalayas are touched with the sunlight, so they stand out like signal fires against the darkness that still lies in the valleys..."

Waverly touched another button and the voice stopped. "The Wheel has maintained voice transmission approximately two-thirds of the time since. It has all been recorded, and has been subjected to intensive analysis by Section Four. There has been no indication in any of the material of any specific national origin."

He leaned back and fumbled for his pipe. Napoleon, Illya and Suzie sat erect, staring at the projection of the Monster Wheel. Finally Napoleon spoke:

"Do you think the mysterious rocket launching site we're after could be involved in this problem too?"

"There's an ancient saying in my country," said Illya, "to the effect that when you have two pieces of a jigsaw puzzle that will fit nowhere else, they may fit together."

"Ancient saying?"

"Comparatively ancient."

Waverly returned to the conversation, having completed his own project, which was now smoldering between his teeth. He took it out, and replaced it with a statement:

"That monstrous wheel represents possibly the greatest threat to the security of the entire world in history. Whoever controls it can control any spot on the surface of the planet except for a few thousand square miles at the poles. From such a stable platform, every major operation can be studied with relatively simple telescopes, and thermonuclear missiles can be placed with a maximum of accuracy and a minimal expenditure of energy. And as long as we don't know who controls it, we remain unable to strike back."

"Couldn't we send a missile up to the Wheel?" asked Suzie.

"They could track it and destroy it at their leisure—and destroy as well its launching site and the nation that launched it."

The two agents considered this for a while. Illya finally spoke: "That seems to leave us with only one choice."

Napoleon nodded. "Find their launching site."

"Exactly," said Waverly. He glanced at Suzie. "And I'm afraid I must insist you do it alone. I understand your personal involvement in this operation, Miss Danz, but this is a job for professional personnel." He turned back to the two men.

"Section Three has filed an interrogation report on your Egyptian trophy. He stood up quite well as far as we dared go with him—gave only his name and nationality, and insisted that his rights under international law were being violated. He was right, of course—they were. We confronted him with the photos we have of the Monster Wheel, though, and they seemed to catch him off balance.

Waverly paused to inspect his pipe, which seemed to have gone out. He took his time puffing its dormant embers back into life, and then spoke again. "He claimed it belonged to his own nation."

"To Egypt!" said three voices simultaneously.

"To Egypt. The interrogators pointed out to him that this was obviously ridiculous, but he continued to insist for a few exchanges, then suddenly shut up. He said if his government hadn't seen fit to announce it to the world, he would respect their judgment. And they could get nothing more out of him.

"Also, Mr. Schneider has recovered rather well from the drugs he was given in Australia. And we are now in possession of the coordinates of the mysterious island."

"Have we identified it?" asked Illya.

"Yes, we have. Few charts bother to list it, since it is tiny, uninhabited, has no natural fresh water, and is far off the main trade routes. It is a volcanic island, with a single peak at two thousand and some feet above sea level. The last reported activity of the volcano was in 1872. It is now officially considered extinct. The island itself is moderately jungled, and is roughly two miles from east to west, three miles north to south.

"A photo-reconnaissance aircraft has been ordered over the island—more than one would probably arouse the suspicions of anyone who might be there and equipped to observe it. The results of the mission will be in our hands by tomorrow afternoon, and a topographical map will be prepared for your use.

"Friday you will depart by jet to our branch office in Colombo, Ceylon, where you will board a special ship. You will be put over the side in a miniature submarine some two hundred miles from the island, and will proceed to infiltrate whatever operation may be centered there. Obtain as much information as you can regarding the nature and especially the source of supply for the operation, and get out again. You will then be picked up by the same ship at the spot you left it. All details beyond these will be left to your own discretions."

"Fine," said Napoleon crisply. "We'll want camouflage suits, some basic guerilla equipment and survival gear. Also two scuba outfits. And if at all possible, a map of underwater contours around the island. We'll want to sink the sub in fifty or a hundred feet of water, where it'll be safe while we're ashore."

"Section Five will get to work on the map tonight. Incidentally, you should plan to spend tomorrow down in the Research Department. Mr. Simpson will want to check you out on the new submarine."
