"Who is the girl?" he asked at last.

"Dorothy Vaneman, the daughter of the lawyer. She's that auburn-haired beauty that the papers were so full of when she came out last year."

"Vaneman is a director in the Seaton-Crane Company. That makes it still better. If they show fight and follow us, that beautiful car we are making for them will collapse and they will be out of the way. Vaneman, as Seaton's prospective father-in-law and a member of his company, probably knows something about the secret. Maybe all of it. With his daughter in a space-car, supposedly out in space, and Seaton and Crane out of the way, Vaneman would listen to reason and let go of the solution, particularly as nobody knows much about it except Seaton and Crane."

"That strikes me as a perfectly feasible plan," said Brookings. "But you wouldn't really take her to another planet, would you? Why not use an automobile or an airplane, and tell Seaton that it was a space-car?"

"I wouldn't advise that. He might not believe it, and they might make a lot of trouble. It must be a real space-car even if we don't take her out of the city. To make it more impressive, you should take her in plain sight of Seaton--no, that would be too dangerous, as I have found out from the police that Seaton has a permit to carry arms, and I know that he is one of the fastest men with a pistol in the whole country. Do it in plain sight of her folks, say, or a crowd of people; being masked, of course, or dressed in an aviator's suit, with the hood and goggles on. Take her straight up out of sight, then hide her somewhere until Seaton listens to reason. I know that he _will_ listen, but if he doesn't, you might let him see you start out to visit her. He'll be sure to follow you in their rotten car. As soon as he does that, he's our meat. But that raises the question of who is going to drive the car?"

"I am," replied DuQuesne. "I will need some help, though, as at least one man must stay with the girl while I bring the car back."

"We don't want to let anybody else in on this if we can help it,"

cautioned Brookings. "You could go along, couldn't you, Perkins?"

"Is it safe?"

"Absolutely," answered DuQuesne. "They have everything worked out to the queen's taste."

"That's all right, then. I'll take the trip. Also," turning to Brookings, "it will help in another little thing we are doing--the Spencer affair."

"Haven't you got that stuff away from her yet, after having had her locked up in that hell-hole for two months?" asked Brookings.

"No. She's stubborn as a mule. We've given her the third degree time after time, but it's no use."

"What's this?" asked DuQuesne. "Deviltry in the main office?"

"Yes. This Margaret Spencer claims that we swindled her father out of an invention and indirectly caused his death. She secured a position with us in search of evidence. She is an expert stenographer, and showed such ability that she was promoted until she became my secretary. Our detectives must have been asleep, as she made away with some photographs and drawings before they caught her. She has no real evidence, of course, but she might cause trouble with a jury, especially as she is one of the best-looking women in Washington. Perkins is holding her until she returns the stolen articles."

"Why can't you kill her off?"

"She cannot be disposed of until after we know where the stuff is, because she says, and Perkins believes, that the evidence will show up in her effects. We must do something about her soon, as the search for her is dying down and she will be given up for dead."

"What's the idea about her and the space-car?"

"If the car proves reliable we might actually take her out into space and give her the choice between telling and walking back. She has nerve enough here on earth to die before giving up, but I don't believe any human being would be game to go it alone on a strange world. She'd wilt."

"I believe you're right, Perkins. Your suggestions are the best way out.

Don't you think so, Doctor?"

"Yes, I don't see how we can fail--we're sure to win, either way. You are prepared for trouble afterward, of course?"

"Certainly, but I don't think there will be much trouble. They can't possibly link the three of us together. They aren't wise to you, are they, Doctor?"

"Not a chance!" sneered DuQuesne. "They ran themselves ragged trying to get something on me, but they couldn't do it. They have given me up as a bad job. I am still as careful as ever, though--I am merely a pure scientist in the Bureau of Chemistry!"

All three laughed, and Perkins left the room. The talk then turned to the construction of the space-car. It was decided to rush the work on it, so that DuQuesne could familiarize himself with its operation, but not to take any steps in the actual abduction until such time as Seaton and Crane were nearly ready to take their first flight, so that they could pursue the abductors in case Seaton was still obdurate after a few days of his fiancee's absence. DuQuesne insisted that the car should mount a couple of heavy guns, to destroy the pursuing car if the faulty members should happen to hold together long enough to carry it out into space.

After a long discussion, in which every detail of the plan was carefully considered, the two men left the restaurant, by different exits.

CHAPTER VII

The Trial Voyage

The great steel forgings which were to form the framework of the Skylark finally arrived and were hauled into the testing shed. There, behind closed doors, Crane inspected every square inch of the massive members with a lens, but could find nothing wrong. Still unsatisfied, he fitted up an electrical testing apparatus in order to search out flaws which might be hidden beneath the surface. This device revealed flaws in every piece, and after thoroughly testing each one and mapping out the imperfections he turned to Seaton with a grave face.

"Worse than useless, every one of them. They are barely strong enough to stand shipment. They figured that we would go slowly until we were well out of the atmosphere, then put on power--then something would give way and we would never come back."

"That's about the right dope, I guess. But now what'll we do? We can't cancel without letting them know we're onto them, and we certainly can't use this stuff."

"No, but we will go ahead and build this ship, anyway, so that they will think that we are going ahead with it. At the same time we will build another one, about four times this size, in absolute secrecy, and...."

"What d'you mean, absolute secrecy? How can you keep steel castings and forgings of that size secret from Steel?"

"I know a chap who owns and operates a small steel plant, so insignificant, relatively, that he has not yet been bought out or frozen out by Steel. I was able to do him a small favor once, and I am sure that he will be glad to return it. We will not be able to oversee the work, that is a drawback. We can get MacDougall to do it for us, however, and with him doing the work we can rest assured that there will be nothing off color. Even Steel couldn't buy _him_."

"MacDougall! The man who installed the Intercontinental plant? He wouldn't touch a little job like this with a pole!"

"I think he would. He and I are rather friendly, and after I tell him all about it he will be glad to take it. It means building the first interplanetary vessel, you know."

"Wouldn't Steel follow him up if he should go to work on a mysterious project? He's too big to hide."

"No. He will go camping--he often does. I have gone with him several times when we were completely out of touch with civilization for two months at a time. Now, about the ship we want. Have you any ideas?"

"It will cost more than our entire capital."

"That is easily arranged. We do not care how much it costs."

Seaton began to object to drawing so heavily upon the resources of his friend, but was promptly silenced.

"I told you when we started," Crane said flatly, "that your solution and your idea are worth far more than half a million. In fact, they are worth more than everything I have. No more talk of the money end of it, Dick."

"All right. We'll build a regular go-getter. Four times the size--she'll be a bear-cat, Mart. I'm glad this one is on the fritz. She'll carry a two-hundred-pound bar--Zowie! Watch our smoke! And say, why wouldn't it be a good idea to build an attractor--a thing like an object-compass, but mounting a ten-pound bar instead of a needle, so that if they chase us in space we can reach out and grab 'em? We might mount a machine-gun in each quadrant, shooting X-plosive bullets, through pressure gaskets in the walls. We should have something for defense--I don't like the possibility of having that gang of pirates after us, and nothing to fight back with except thought-waves."

"Right. We will do both those things. But we should make the power-plant big enough to avert any possible contingency--say four hundred pounds--and we should have everything in duplicate, from power-plant to push-buttons."

"I don't think that's necessary, Mart. Don't you think that's carrying caution to extremes?"

"Possibly--but I would rather be a live coward than a dead hero, wouldn't you?"

"You chirped it, old scout, I sure would. I never did like the looks of that old guy with the scythe, and I would hate to let DuQuesne feel that he had slipped something over on me at my own game. Besides, I've developed a lot of caution myself, lately. Double she is, with a skin of four-foot Norwegian armor. Let's get busy!"
