"Hi, Stella," he grinned. "Mr. Andrusco in his office?"

"Why, I don't know. Suppose I give him a ring--"

He stopped the hand that was reaching for the telephone. "No need of that. I think I'll just surprise him. After all, it's been some time."

He turned the k.n.o.b of John Andrusco's door slowly.

Livia was with him. When he entered, they both stood up hastily, their eyes wide and their mouths unhinged.

Livia reacted first. She cried out his name, and then sat down heavily, as if the words had been a physical force.

"Hi, Livia," Tom said casually. "Good to see you again, Mr. Andrusco.

Sorry that I haven't been around--but things have been pretty hectic for me lately."

"How did you get here?" Andrusco's voice was choked.

"I've been here all weekend, if you want to know." Tom seated himself blithely. "As a matter of fact, the Homelovers Building has had quite a lot of visitors this weekend."

"What do you mean?"

"You know the staff of cleaning personnel that invades this place every Sat.u.r.day? Well, there were some changes made this particular weekend.

I'm sure you'll be interested in hearing about them."

Livia said: "Shall I call the police, John?"

"The police were represented," Tom said. "Don't worry about that. In fact, the top technicians from three government agencies were doing the housework around here this weekend, Mr. Andrusco. They probably didn't get the building much cleaner--but they swept up a lot of other things.

Yes, they certainly uncovered other things."

Andrusco walked over to Livia, and touched her shoulder in a comforting gesture. The sight of them made Tom scowl.

"All right!" he said roughly. "I'm not blaming you for what you're doing. But things were getting out of hand, Mr. Andrusco. That's why we had to put a stop to it."

"And have you?" Andrusco asked politely.

"I'm afraid so. It was quite a shock, let me tell you. We didn't know what to expect when we dissected this building of yours. But the last thing we expected to find was--a s.p.a.ceship."

Andrusco smiled. "It was cleverly done. You'll have to admit that."

"I do," Tom said fervently. "You've got those s.p.a.ce flight experts absolutely insane with curiosity. They'll want to hear the whole story.

Will you give it to them?"

The man shrugged. "It doesn't matter, I suppose. I presume the engines have been dismantled?"

"Made inoperable, yes. It would have been a great trick, if you could have done it."

Livia spoke sadly. "It was the only thing we could have done. There's no place on this Earth where we could have erected a s.p.a.ceship without being observed. So we created this building. In time, we would have perfected the mechanism and left this silly planet of yours."

"That's what I don't understand," Tom said. "What about Antamunda--and the survivors--"

"There's no longer an Antamunda," John Andrusco said hollowly. "The story we told you was true in its essence, but not, I'm afraid complete.

You see, the exodus that took place five hundred years ago was a total exodus. The entire population of our world--a handful, a pitiful ragged thousand--left Antamunda for this planet. We thought to make it our new home, for all eternity. But in time, we learned that we had emigrated to an extinction just as certain."

"What do you mean?"

"This world is cursed to us, Mr. Blacker. I can't tell you why. We breed slowly, infrequently--you might even say, thoughtfully. And on your planet, but one child in a thousand has survived the rigors of childbirth on Earth." He looked at Livia, and the woman lowered her eyes in remembered sorrow.

"That's why we had to leave," Andrusco said. "To repopulate elsewhere.

We chose the planet Mars, and we were determined to make it our home before your world claimed it. Our scientists and technicians have worked on nothing else but this flight since the beginning of the last century.

This building--this vessel--was the culmination of our plans. In another few years, we would have been ready. The dream would have been realized."

Tom walked to the window of the office, and looked out at a bank of swift-moving clouds drifting past the spire of the Homelovers Building.

"I'm afraid that's the saddest part," he said. "The atomic engines in the bas.e.m.e.nt have been examined, Mr. Andrusco. The best opinions say that they're pitifully inadequate. The men who studied them say that you would never have made the journey in safety."

"That can't be true! In time--"

"In time, perhaps. But since your landing here, your scientists have forgotten a great deal about s.p.a.ce flight. I'm afraid you would have never reached that Promised Land ..."

Andrusco said: "Then we must die ..."

"No!" Tom said.

Livia looked at him.

"I said no!" he repeated. "The Antamundans can live. Don't you see that?"

"No," Andrusco said, shaking his head. "On Earth, we shall die. If Mars is closed to us ..."

"Can't you see? If Mars can be opened for Earth, then it can be opened for you, too. For all Antamundans! Your people can make the journey, too, once s.p.a.ce has been cleared for Earth ships. You can still have your new home!"

"Perhaps," Livia said dreamily. "Perhaps that is the only way. But by then, Tom, it will be already too late. There has been no living child born to us in the last ten years. By the time the Earth people reach Mars and establish regular pa.s.sageway--we will be too old to keep the race alive."

"Then let's speed it up!" he said. "Let's make _sure_ that the s.p.a.ce lanes open! Let's do everything to make s.p.a.ce the most important project on Earth!"

"But how?" Andrusco said, bewildered.

Tom went to the visiphone.

"Get me the Lunt Theatre!" he snapped.

Homer Bradshaw's face appeared.
