The big stratoliner slowed rapidly as it approached the Peiping People’s Airfield. The pilot, a big-boned Britisher who had two jobs to do at once, watched the airspeed indicator. As the needle dropped, he came in on a conventional landing lane, aiming for the huge field below. Then, as the needle reached a certain point, just above the landing minimum, he closed his eyes for a fraction of a second and thought, with all the mental power at his command: NOW!

For a large part of a second, nothing happened, but the pilot knew his message had been received.

Then a red gleam came into being on the control board.

“What the hell?” said the co-pilot.

The pilot swore. “I told ’em that door was weak! We’ve ripped the luggage door off her hinges. Feel her shake?”

The co-pilot looked grim. “Good thing it happened now instead of in mid-flight. At that speed, we’d been torn apart.”

“Blown to bits, you mean,” said the pilot. “Let’s bring her in.”

By that time, Spencer Candron was a long way below the ship, falling like a stone, a big suitcase clutched tightly in his arms. He knew that the Chinese radar was watching the jetliner, and that it had undoubtedly picked up two objects dropping from the craft—the door and one other. Candron had caught the pilot’s mental signal—anything that powerful could hardly be missed—and had opened the door and leaped.

But those things didn’t matter now. Without a parachute, he had flung himself from the plane toward the earth below, and his only thought was his loathing, his repugnance, for that too, too solid ground beneath.

He didn’t hate it. That would be deadly, for hate implies as much attraction as love—the attraction of destruction. Fear, too, was out of the question; there must be no such relationship as that between the threatened and the threatener. Only loathing could save him. The earth beneath was utterly repulsive to him.

And he slowed.

His mind would not accept contact with the ground, and his body was forced to follow suit. He slowed.

Minutes later, he was drifting fifty feet above the surface, his altitude held steady by the emotional force of his mind. Not until then did he release the big suitcase he had been holding. He heard it thump as it hit, breaking open and scattering clothing around it.

In the distance, he could hear the faint moan of a siren. The Chinese radar had picked up two falling objects. And they would find two: one door and one suitcase, both of which could be accounted for by the “accident.” They would know that no parachute had opened; hence, if they found no body, they would be certain that no human being could have dropped from the plane.

The only thing remaining now was to get into the city itself. In the darkness, it was a little difficult to tell exactly where he was, but the lights of Peiping weren’t far away, and a breeze was carrying him toward it. He wanted to be in just the right place before he set foot on the ground.

By morning, he would be just another one of the city’s millions.

Morning came three hours later. The sun came up quietly, as if its sole purpose in life were to make a liar out of Kipling. The venerable old Chinese gentleman who strolled quietly down Dragon Street looked as though he were merely out for a placid walk for his morning constitutional. His clothing was that of a middle-class office worker, but his dignified manner, his wrinkled brown face, his calm brown eyes, and his white hair brought respectful looks from the other passers-by on the Street of the Dragon. Not even the thirty-five years of Communism, which had transformed agrarian China into an industrial and technological nation that ranked with the best, had destroyed the ancient Chinese respect for age.

That respect was what Spencer Candron relied on to help him get his job done. Obvious wealth would have given him respect, too, as would the trappings of power; he could have posed as an Honorable Director or a People’s Advocate. But that would have brought unwelcome attention as well as respect. His disguise would never stand up under careful examination, and trying to pass himself off as an important citizen might bring on just such an examination. But an old man had both respect and anonymity.

Candron had no difficulty in playing the part. he had known many elderly chinese, and he understood them well. even the emotional control of the oriental was simple to simulate; candron knew what “emotional control” really meant.

You don’t control an automobile by throwing the transmission out of gear and letting the engine run wild. Suppressing an emotion is not controlling it, in the fullest sense. “Control” implies guidance and use.

Peiping contained nearly three million people in the city itself, and another three million in the suburbs; there was little chance that the People’s Police would single out one venerable oldster to question, but Candron wanted an escape route just in case they did. He kept walking until he found the neighborhood he wanted, then he kept his eyes open for a small hotel. He didn’t want one that was too expensive, but, on the other hand, he didn’t want one so cheap that the help would be untrustworthy.

He found one that suited his purpose, but he didn’t want to go in immediately. There was one more thing to do. He waited until the shops were open, and then went in search of second-hand luggage. He had enough money in his pockets to buy more brand-new expensive luggage than a man could carry, but he didn’t want luggage that looked either expensive or new. When he finally found what he wanted, he went in search of clothing, buying a piece at a time, here and there, in widely scattered shops. Some of it was new, some of it was secondhand, all of it fit both the body and the personality of the old man he was supposed to be. Finally, he went to the hotel.

The clerk was a chubby, blandly happy, youngish man who bowed his head as Candron approached. There was still the flavor of the old politeness in his speech, although the flowery beauty of half a century before had disappeared.

“Good morning, venerable sir; may I be of some assistance?”

Candron kept the old usages. “This old one would be greatly honored if your excellent hostelry could find a small corner for the rest of his unworthy body,” he said in excellent Cantonese.

“It is possible, aged one, that this miserable hovel may provide some space, unsuited though it may be to your honored presence,” said the clerk, reverting as best he could to the language of a generation before. “For how many people would you require accommodations?”

“For my humble self only,” Candron said.

“It can, I think, be done,” said the clerk, giving him a pleasant smile. Then his face took on an expression of contrition. “I hope, venerable one, that you will not think this miserable creature too bold if he asks for your papers?”

“Not at all,” said Candron, taking a billfold from his inside coat pocket. “Such is the law, and the law of the People of China is to be always respected.”

He opened the billfold and spread the papers for the clerk’s inspection. They were all there—identification, travel papers, everything. The clerk looked them over and jotted down the numbers in the register book on the desk, then turned the book around. “Your chop, venerable one.”

The “chop” was a small stamp bearing the ideograph which indicated the name Candron was using. Illiteracy still ran high in China because of the difficulty in memorizing the tens of thousands of ideographs which made up the written language, so each man carried a chop to imprint his name. Officially, China used the alphabet, spelling out the Chinese words phonetically—and, significantly, they had chosen the Latin alphabet of the Western nations rather than the Cyrillic of the Soviets. But old usages die hard.

Candron imprinted the ideograph on the page, then, beside it, he wrote “Ying Lee” in Latin characters.

The clerk’s respect for this old man went up a degree. He had expected to have to put down the Latin characters himself. “Our humble establishment is honored by your esteemed presence, Mr. Ying,” he said. “For how long will it be your pleasure to bestow this honor upon us?”

“My poor business, unimportant though it is, will require it least one week; at the most, ten days.” Candron said, knowing full well that twenty-four hours would be his maximum, if everything went well.

“It pains me to ask for money in advance from so honorable a gentleman as yourself,” said the clerk, “but such are the rules. It will be seven and a half yuan per day, or fifty yuan per week.”

Candron put five ten-yuan notes on the counter. Since the readjustment of the Chinese monetary system, the yuan had regained a great deal of its value.

A young man who doubled as bellhop and elevator operator took Candron up to the third floor. Candron tipped him generously, but not extravagantly, and then proceeded to unpack his suitcase. He hung the suits in the closet and put the shirts in the clothes chest. By the time he was through, it looked as though Ying Lee was prepared to stay for a considerable length of time.

Then he checked his escape routes, and found two that were satisfactory. Neither led downward to the ground floor, but upward, to the roof. The hotel was eight stories high, higher than any of the nearby buildings. No one would expect him to go up.

Then he gave his attention to the room itself. He went over it carefully, running his fingers gently over the walls and the furniture, noticing every detail with his eyes. He examined the chairs, the low bed, the floor—everything.

He was not searching for spy devices. He didn’t care whether there were any there or not. He wanted to know that room. To know it, become familiar with it, make it a part of him.

Had there been any spy devices, they would have noticed nothing unusual. There was only an old man there, walking slowly around the room, muttering to himself as though he were thinking over something important or, perhaps, merely reminiscing on the past, mentally chewing over his memories.

He did not peer, or poke, or prod. He did not appear to be looking for anything. He picked up a small, cheap vase and looked at it as though it were an old friend; he rubbed his hand over the small writing desk, as though he had written many things in that familiar place; he sat down in a chair and leaned back in it and caressed the armrests with his palms as though it were an honored seat in his own home. And, finally, he undressed, put on his nightclothes, and lay down on the bed, staring at the ceiling with a soft smile on his face. After ten minutes or so, his eyes closed and remained that way for three-quarters of an hour.

Unusual? No. An old man must have his rest. There is nothing unusual about an old man taking a short nap.

When he got up again, Spencer Candron was thoroughly familiar with the room. It was home, and he loved it.

Nightfall found the honorable Mr. Ying a long way from his hotel. He had, as his papers had said, gone to do business with a certain Mr. Yee, had haggled over the price of certain goods, and had been unsuccessful in establishing a mutual price. Mr. Yee was later to be able to prove to the People’s Police that he had done no business whatever with Mr. Ying, and had had no notion whatever that Mr. Ying’s business connections in Nanking were totally nonexistent.

But, on that afternoon, Mr. Ying had left Mr. Yee with the impression that he would return the next day with, perhaps, a more amenable attitude toward Mr. Yee’s prices. Then Mr. Ying Lee had gone to a restaurant for his evening meal.

He had eaten quietly by himself, reading the evening edition of the Peiping Truth as he ate his leisurely meal. Although many of the younger people had taken up the use of the knife and fork, the venerable Mr. Ying clung to the chopsticks of an earlier day, plied expertly between the thumb and forefinger of his right hand. He was not the only elderly man in the place who did so.

Having finished his meal and his newspaper in peace, Mr. Ying Lee strolled out into the gathering dusk. By the time utter darkness had come, and the widely-spaced street lamps of the city had come alive, the elderly Mr. Ying Lee was within half a mile of the most important group of buildings in China.

The Peiping Explosion, back in the sixties, had almost started World War Three. An atomic blast had leveled a hundred square miles of the city and started fires that had taken weeks to extinguish. Soviet Russia had roared in its great bear voice that the Western Powers had attacked, and was apparently on the verge of coming to the defense of its Asian comrade when the Chinese government had said irritatedly that there had been no attack, that traitorous and counterrevolutionary Chinese agents of Formosa had sabotaged an atomic plant, nothing more, and that the honorable comrades of Russia would be wise not to set off anything that would destroy civilization. The Russian Bear grumbled and sheathed its claws.

The vast intelligence system of the United States had reported that (A) the explosion had been caused by carelessness, not sabotage, but the Chinese had had to save face, and (B) the Soviet Union had no intention of actually starting an atomic war at that time. If she had, she would have shot first and made excuses afterwards. But she had hoped to make good propaganda usage of the blast.

The Peiping Explosion had caused widespread death and destruction, yes; but it had also ended up being the fastest slum-clearance project on record. The rebuilding had taken somewhat more time than the clearing had taken, but the results had been a new Peiping—a modern city in every respect. And nowhere else on Earth was there one hundred square miles of completely modern city. Alteration takes longer than starting from scratch if the techniques are available; there isn’t so much dead wood to clear away.

In the middle of the city, the Chinese government had built its equivalent of the Kremlin—nearly a third of a square mile of ultra-modern buildings designed to house every function of the Communist Government of China. It had taken slave labor to do the job, but the job had been done.

A little more than half a mile on a side, the area was surrounded by a wall that had been designed after the Great Wall of China. It stood twenty-five feet high and looked very quaint and picturesque.

And somewhere inside it James Ch’ien, American-born physicist, was being held prisoner. Spencer Candron, alias Mr. Ying Lee, had to get him out.

Dr. Ch’ien was important. The government of the United States knew he was important, but they did not yet know how important he was.

Man had already reached the Moon and returned. The Martian expedition had landed safely, but had not yet returned. No one had heard from the Venusian expedition, and it was presumed lost. But the Moon was being jointly claimed by Russian and American suits at the United Nations, while the United Nations itself was trying to establish a claim. The Martian expedition was American, but a Russian ship was due to land in two months. The lost Venusian expedition had been Russian, and the United States was ready to send a ship there.

After nearly forty years, the Cold War was still going on, but now the scale had expanded from the global to the interplanetary.

And now, up-and-coming China, defying the Western Powers and arrogantly ignoring her Soviet allies, had decided to get into the race late and win it if she could.

And she very likely could, if she could exploit the abilities of James Ch’ien to the fullest. If Dr. Ch’ien could finish his work, travel to the stars would no longer be a wild-eyed idea; if he could finish, spatial velocities would no longer be limited to the confines of the rocket, nor even to the confines of the velocity of light. Man could go to the stars.

The United States Federal Government knew—or, at least, the most responsible officers of that government knew—that Ch’ien’s equations led to interstellar travel, just as Einstein’s equations had led to atomic energy. Normally, the United States would never have allowed Dr. Ch’ien to attend the International Physicists Conference in Peiping. But diplomacy has its rules, too.

Ch’ien had published his preliminary work—a series of highly abstruse and very controversial equations—back in ’80. The paper had appeared in a journal that was circulated only in the United States and was not read by the majority of mathematical physicists. Like the work of Dr. Fred Hoyle, thirty years before, it had been laughed at by the majority of the men in the field. Unlike Hoyle’s work, it had never received any publicity. Ch’ien’s paper had remained buried.

In ’81, Ch’ien had realized the importance of his work, having carried it further. He had reported his findings to the proper authorities of the United States Government, and had convinced that particular branch of the government that his work had useful validity. But it was too late to cover up the hints that he had already published.

Dr. James Ch’ien was a friendly, gregarious man. He liked to go to conventions and discuss his work with his colleagues. He was, in addition, a man who would never let anything go once he had got hold of it, unless he was convinced that he was up a blind alley. And, as far as Dr. Ch’ien was concerned, that took a devil of a lot of convincing.

The United States government was, therefore, faced with a dilemma. If they let Ch’ien go to the International Conferences, there was the chance that he would be forced, in some way, to divulge secrets that were vital to the national defense of the United States. On the other hand, if they forbade him to go, the Communist governments would suspect that Ch’ien knew something important, and they would check back on his previous work and find his publications of 1980. If they did, and realized the importance of that paper, they might be able to solve the secret of the interstellar drive.

The United States government had figuratively flipped a coin, and the result was that Ch’ien was allowed to come and go as he pleased, as though he were nothing more than just another government physicist.

And now he was in the hands of China.

How much did the Chinese know? Not much, evidently; otherwise they would never have bothered to go to the trouble of kidnaping Dr. James Ch’ien and covering the kidnaping so elaborately. They suspected, yes: but they couldn’t know. They knew that the earlier papers meant something, but they didn’t know what—so they had abducted Ch’ien in the hope that he would tell them.

James Ch’ien had been in their hands now for two months. How much information had they extracted by now? Personally, Spencer Candron felt that they had got nothing. You can force a man to work; you can force him to tell the truth. But you can not force a man to create against his will.

Still, even a man’s will can be broken, given enough time. If Dr. Ch’ien weren’t rescued soon…

Tonight, Candron thought with determination. I’ll get Ch’ien tonight. That was what the S.M.M.R. had sent him to do. And that’s what he would—must—do.

Ahead of him loomed the walls of the Palace of the Great Chinese People’s Government. Getting past them and into the inner court was an act that was discouraged as much as possible by the Special Police guard which had charge of those walls. They were brilliantly lighted and heavily guarded. If Candron tried to levitate himself over, he’d most likely be shot down in midair. They might be baffled afterwards, when they tried to figure out how he had come to be flying around up there, but that wouldn’t help Candron any.

Candron had a better method.

When the automobile carrying the People’s Minister of Finance, the Honorable Chou Lung, went through the Gate of the Dog to enter the inner court of the Palace, none of the four men inside it had any notion that they were carrying an unwanted guest. How could they? The car was a small one; its low, streamlined body carried only four people, and there was no luggage compartment, since the powerful little vehicle was designed only for maneuvering in a crowded city or for fast, short trips to nearby towns. There was simply no room for another passenger, and both the man in the car and the guards who passed it through were so well aware of that fact that they didn’t even bother to think about it. It never occurred to them that a slight, elderly-looking gentleman might be hanging beneath the car, floating a few inches off the ground, holding on with his fingertips, and allowing the car to pull him along as it moved on into the Palace of the Great Chinese People’s Government.

Getting into the subterranean cell where Dr. James Ch’ien was being held was a different kind of problem. Candron knew the interior of the Palace by map only, and the map he had studied had been admittedly inadequate. It took him nearly an hour to get to the right place. Twice, he avoided a patrolling guard by taking to the air and concealing himself in the darkness of an overhead balcony. Several other times, he met men in civilian clothing walking along the narrow walks, and he merely nodded at them. He looked too old and too well-dressed to be dangerous.

The principle that made it easy was the fact that no one expects a lone man to break into a heavily guarded prison.

After he had located the building where James Ch’ien was held, he went high-flying. The building itself was one which contained the living quarters of several high-ranking officers of the People’s Government. Candron knew he would be conspicuous if he tried to climb up the side of the building from the outside, but he managed to get into the second floor without being observed. Then he headed for the elevator shafts.

It took him several minutes to jimmy open the elevator door. His mind was sensitive enough to sense the nearness of others, so there was no chance of his being caught red-handed. When he got the door open, he stepped into the shaft, brought his loathing for the bottom into the fore, and floated up to the top floor. From there it was a simple matter to get to the roof, drop down the side, and enter the open window of an officer’s apartment.

He entered a lighted window rather than a darkened one. He wanted to know what he was getting into. He had his gun ready, just in case, but there was no sign of anyone in the room he entered. A quick search showed that the other two rooms were also empty. His mind had told him that there was no one awake in the apartment, but a sleeping man’s mind, filled with dimmed, chaotic thoughts, blended into the background and might easily be missed.
