“All right. If you agree, we’ll both stick our necks out.” Lludrow looked at the door of the office, but it was firmly closed. “I’m going to violate top security and enlist you in an action contrary to Staff orders, if you don’t mind.”

“Top security?” echoed Donal, feeling a sudden coolness at the back of his neck.

“Yes. We’ve discovered what was behind this Newton-Cassida landing on Oriente . . . you know Oriente?”

“I’ve studied it, of course,” said Donal. “At school—and recently when I signed with Freiland. Temperatures up to seventy-eight degrees centigrade, rock, desert, and a sort of native vine and cactus jungle. No large bodies of water worth mentioning and too much carbon dioxide in the atmosphere.”

“Right. Well,” said Lludrow, “the important point is, it’s big enough to hide in. They’re down there now and we can’t root them out in a hurry—and not at all unless we go down there after them. We thought they were making the landing as a live exercise and we could expect them to run the gauntlet back out in a few days or weeks. We were wrong.”

“Wrong?”

“We’ve discovered their reason for making the landing on Oriente. It wasn’t what we thought at all.”

“That’s fast work,” said Donal. “What’s it been . . . four hours since the landing?”

“They made fast work of it,” said Lludrow. “The news is being sat on; but they are firing bursts of a new kind of radiation from projectors that fire once, move, and fire again from some new hiding place—a large number of projectors. And the bursts they fire hit old Sirius himself. We’re getting increased sunspot activity.” He paused and looked keenly at Donal, as if waiting for comment. Donal took his time, considering the situation.

“Weather difficulties?” he said at last.

“That’s it!” said Lludrow, energetically, as though Donal had been a star pupil who had just shone again. “Meteorological opinion says it can be serious, the way they’re going about it. And we’ve already heard their price for calling it off. It seems there’s a trade commission of theirs on New Earth right now. No official connection—but the Commission’s got the word across.”

Donal nodded. He was not at all surprised to hear that trade negotiations were going on in normal fashion between worlds who were at the same time actively fighting each other. That was the normal course of existence between the stars. The ebb and flow of trained personnel on a contractual basis was the lifeblood of civilization. A world who tried to go it on its own would be left behind within a matter of years, to wither on the vine—or at last buy the mere necessities of existence at ruinous cost to itself. Competition meant the trading of skilled minds, and that meant contracts, and contracts meant continuing negotiations.
