The Belt Cities could survive without the help of Earth, and the Supreme Congress of the United Nations of Earth knew it. But they also knew that "survive" did not by any means have the same semantic or factual content as "live comfortably". If Earth were to vanish overnight, the people of the Belt would live, but they would be seriously handicapped. On the other hand, the people of Earth could survive—as they had for millennia—without the Belt Cities, and while doing without Belt imports might be painful, it would by no means be deadly.

But both the Belt Cities and the Earth knew that the destruction of one would mean the collapse of the other as a civilization.

Earth needed iron. Belt iron was cheap. The big iron deposits of Earth were worked out, and the metal had been widely scattered. The removal of the asteroids as a cheap source would mean that iron would become prohibitively expensive. Without cheap iron, Earth's civilization would have to undergo a painfully drastic change—a collapse and regeneration.

But the Belt Cities were handicapped by the fact that they had had as yet neither the time nor the resources to manufacture anything but absolute necessities. Cloth, for example, was imported from Earth. A society that is still busy struggling for the bare necessities—such as manufacturing its own air—has no time to build the huge looms necessary to weave cloth ... or to make clothes, except on a minor scale. Food? You can have hydroponic gardens on an asteroid, but raising beef cattle, even on Ceres, was difficult. Eventually, perhaps, but not yet.

The Belt Cities were populated by pioneers who still had not given up the luxuries of civilization. Their one weakness was that they had their cake and were happily eating it, too.

Not that Harry Morgan didn't realize that fact. A Belt man is, above all, a realist, in that he must, of necessity, understand the Laws of the Universe and deal with them. Or die.

Commodore Sir Harry Morgan was well aware of the stir he had created in the lobby of the Grand Central Hotel. Word would leak out, and he knew it. The scene had been created for just that purpose.

He sang with gusto as the elevator lifted him up to the seventy-fourth floor of the Grand Central Hotel. The other passengers in the car did not look at him directly; they cast sidelong glances.

This guy, they seemed to think in unison, is a nut. We will pay no attention to him, since he probably does not really exist. Even if he does, we will pay no attention in the hope that he will go away.

On the seventy-fourth floor, he did go away, heading for his room. He keyed open the door and strolled over to the phone, where a message had already been dropped into the receiver slot. He picked it up and read it.

"How news travels," Harry Morgan thought to himself. He tapped out the number on the keyboard of the phone and waited for the panel to light up. When it did, it showed a man in his middle fifties with a lean, ascetic face and graying hair, which gave him a look of saintly wisdom.

"Mr. Tarnhorst?" Morgan asked pleasantly.

"Yes. Commodore Morgan?" The voice was smooth and precise.

"At your service, Mr. Tarnhorst. You asked me to call."

"Yes. What is the purpose of your visit to Earth, commodore?" The question was quick, decisive, and firm.

Harry Morgan kept his affability. "That's none of your business, Mr. Tarnhorst."

Tarnhorst's face didn't change. "Perhaps your superiors haven't told you, but—and I can only disclose this on a sealed circuit—I am in sympathy with the Belt Cities. I have been out there twice and have learned to appreciate the vigor and worth of the Belt people. I am on your side, commodore, in so far as it does not compromise my position. My record shows that I have fought for the rights of the Belt Cities on the floor of the Supreme Congress. Have you been informed of that fact?"

"I have," said Harry Morgan. "And that is precisely why it is none of your business. The less you know, Mr. Tarnhorst, the safer you will be. I am not here as a representative of any of the City governments. I am not here as a representative of any of the Belt Corporations. I am completely on my own, without official backing. You have shown yourself to be sympathetic towards us in the past. We have no desire to hurt you. Therefore I advise that you either keep your nose out of my business or actively work against me. You cannot protect yourself otherwise."

Edward Tarnhorst was an Earthman, but he was not stupid. He had managed to put himself in a position of power in the Welfare World, and he knew how to handle that power. It took him exactly two seconds to make his decision.

"You misunderstand me, commodore," he said coldly. "I asked what I asked because I desire information. The People's Government is trying to solve the murder of Commodore Jack Latrobe. Assuming, of course, that it was murder—which is open to doubt. His body was found three days ago in Fort Tryon Park, up on the north end of Manhattan Island. He had apparently jumped off one of the old stone bridges up there and fell ninety feet to his death. On the other hand, it is possible that, not being used to the effects of a field of point nine eight Standard gees, he did not realize that the fall would be deadly, and accidentally killed himself. He was alone in the park at night, as far as we can tell. It has been ascertained definitely that no representative of the People's Manufacturing Corporation Number 873 was with him at the time. Nor, so far as we can discover, was anyone else. I asked you to call because I wanted to know if you had any information for us. There was no other reason."

"I haven't seen Jack since he left Juno," Morgan said evenly. "I don't know why he came to Earth, and I know nothing else."

"Then I see no further need for conversation," Tarnhorst said. "Thank you for your assistance, Commodore Morgan. If Earth's Government needs you again, you will be notified if you gain any further information, you may call this number. Thank you again. Good-by."

The screen went blank.

How much of this is a trap? Morgan thought.

There was no way of knowing at this point. Morgan knew that Jack Latrobe had neither committed suicide nor died accidentally, and Tarnhorst had told him as much. Tarnhorst was still friendly, but he had taken the hint and got himself out of danger. There had been one very important piece of information. The denial that any representative of PMC 873 had been involved. PMC 873 was a manufacturer of biological products—one of the several corporations that Latrobe had been empowered to discuss business with when he had been sent to Earth by the Belt Corporations Council. Tarnhorst would not have mentioned them negatively unless he intended to imply a positive hint. Obviously. Almost too obviously.

Well?

Harry Morgan punched for Information, got it, got a number, and punched that.

"People's Manufacturing Corporation Ey-yut Seven Tha-ree," said a recorded voice. "Your desire, pu-leeze?"

"This is Commodore Jack Latrobe," Morgan said gently. "I'm getting tired of this place, and if you don't let me out I will blow the whole place to Kingdom Come. Good bye-eye-eye."

He hung up without waiting for an answer.

Then he looked around the hotel suite he had rented. It was an expensive one—very expensive. It consisted of an outer room—a "sitting room" as it might have been called two centuries before—and a bedroom. Plus a bathroom.

Harry Morgan, a piratical smile on his face, opened the bathroom door and left it that way. Then he went into the bedroom. His luggage had already been delivered by the lift tube, and was sitting on the floor. He put both suitcases on the bed, where they would be in plain sight from the sitting room. Then he made certain preparations for invaders.

He left the door between the sitting room and the bedroom open and left the suite.

Fifteen minutes later, he was walking down 42nd Street toward Sixth Avenue. On his left was the ancient Public Library Building. In the middle of the block, somebody shoved something hard into his left kidney and said. "Keep walking, commodore. But do what you're told."

Harry Morgan obeyed, with an utterly happy smile on his lips.
