"It was an interesting job," said Vale. "The Army dumped a hundred tons of high explosive into the lake. The two radars that reported a ship in s.p.a.ce were arranged to be operated by two special men, who got their orders directly from the President. We picked a day with full cloud cover; the radar operators inserted their faked tapes and made their reports; and the Army set off the hundred-ton explosion in the lake. From there on, it was just a matter of using the terror beam."

"I mention," said the general mildly, "that not one human being has been killed by anything we've done. Would you expect traitors to be so careful? Or spies?"

Lockley said thickly, "You stand there arguing. You're trying to make me believe you. But there's Jill! What's happened to her? How did you make her record that tape? Where's Jill? She won't tell me it's all right!"

Headlights swept up to the floodlit s.p.a.ce. The car stopped.

Jill came into view. She saw Lockley, standing against the rocket's base. She ran.

She stood beside the general and Vale and Sattell. She looked worn and desperately anxious.

"What have they done to you?" demanded Lockley fiercely.

She shook her head.

"N-nothing. I couldn't stay at the camp when I was so sure you'd come to try to help me. So I came here. I don't know what they've told you yet, but it's all right. We were fooled as the world has to be.

Believe it! Please believe it!"

"What have they done to you?" he repeated terribly.

"What have they done to the world?" demanded Jill. "They've made every nation look to us as the defender of their freedom. And we are!

They've made everybody ready to fight against more monsters if they come, and to fight against men if they try to enslave them with the terror beam or anything else! Would traitors have done that?"

Lockley knew that he had to decide. It was an unbearable responsibility. He was not convinced, even by Jill. But he was no longer certain that he'd been right.

"Why didn't you kill me?" he demanded. "I could have been shot down from a distance. You didn't have to come close to talk to me. If the rocket blew, what would it matter?"

"You've got a protection against the terror beam," said the general matter-of-factly. "So have we. But ours weighs two tons. Yours can be carried without being a burden. And--" his eyes went to the unlikely cheese grater over Lockley's shoulder--"and yours detonates explosives. If we can equip the world with those, Lockley, we'll have peace!"

Lockley thought of a decisive test. He grimaced.

"You want me to risk being a traitor! All right, what's in it for me?

What am I offered?"

The general shrugged, his eyes hardening. Vale spread out his hands.

Sattell snorted. Jill moistened her lips. Lockley turned upon her.

"You want me to believe," he said harshly. "What do you offer if I turn over the thing to these men you say are honest men and neither spies or traitors. What do you offer?"

She stared at him. Then she said quietly, "Nothing."

Lockley hesitated once more, for a long instant. But that was the right answer. n.o.body who'd been bought or bribed or frightened into being a traitor would have thought of it.

"That," said Lockley, "by a strange coincidence happens to be my price."

He ripped away a wire. He flung the queer combination of pocket radio and cheese and nutmeg graters to the general.

"I'll explain later how it works," he said wearily, "--if I haven't made a mistake."

After a suitable time the general came to him. Lockley was convinced, now. The reaction of the men who'd been guards and truck drivers and the like was conclusive. They regarded him with a certain cordial respect which was not the reaction of either traitors or invaders.

"We've been checking that little device, Lockley," said the general happily. "It's perfect for our purposes! So much better than a two-ton generator to interfere with and cancel the terror beams! Marvelous!

And do you know what it means? With all the world believing we've been attacked from s.p.a.ce, and with our great show of taking back Boulder Lake--"

"How will you manage that?" asked Lockley, without too much interest.

"The rocket," said the general, beaming. "When troops start into the Park, the rocket takes off. It heads for empty s.p.a.ce. And we explain that the aliens went away when they found their weapon useless and we started to get rough with them!"

"Oh," said Lockley listlessly.

"But the really beautiful thing," the general told him, "is your gadget! They can be made by millions. Ridiculously cheap, they tell me. Everybody in the world will want one, and we'll pa.s.s them out. No government could stop that! Not even Russia! But--d'you see, Lockley?"

Lockley shook his head. He always had a tendency to look on the dark side of future events. The future did not look bright to him.

"Don't you see?" demanded the general, chuckling. "They detonate explosives, those little gadgets! There's no harm in that! Where explosives are used in industry you've only to make sure that n.o.body turns one on too close. In nine-tenths of the world, anyhow, civilians aren't allowed to have guns. But think of the consequences there!"

Lockley was weary. He was dejected. The general grinned from ear to ear.

"Why, when these are distributed, even the secret police can't go armed! What price dictators then? For that matter, what price soldiers? The cold war ends, Lockley, because there couldn't be a conquering army in the modern sense. The tanks wouldn't run. The cars would stall. And the guns--An invasion would have to be made with horse-drawn transport and the troops armed with bows and spears. That amounts to disarmament, Lockley! A consummation devoutly to be wished!

I'm going to look forward to a ripe old age now. I never could before!"

Presently Lockley talked to Jill. She was constrained. She seemed uneasy. Lockley felt that there wasn't much to say, now that Vale was alive and well and there was no more danger for her. He offered his hand to say good-bye.

"I think," she said with a little difficulty, "I think I should tell you I'm not--engaged any longer. I--told him I--wouldn't want to be married to someone whose work made him keep secrets from me."

Lockley tensed. He said incredulously, "You're not going to marry Vale?"

She said nervously.

"No-o-o. I've told him."

Lockley swallowed.

"What did he say?"

"He--didn't like it," said Jill. "But he understood. I explained things. He said--he said to congratulate you."

Lockley made an appropriate movement. She wept quietly, held close in his arms.

"I was so afraid you didn't--you wouldn't--"

Lockley took appropriate measures to comfort her and to a.s.sure her that he did and he would, forever and ever. A very long time later he asked interestedly, "What did you say to Vale when he asked you to congratulate me?"

"I said," said Jill comfortably, "that I would if things worked out all right. And they have. I congratulate you, darling. Now how about congratulating me?"
