Fenross reached out a hand which trembled ever so faintly, took a small pillbox and shook a tablet loose. “Haven’t slept in forty hours,” he muttered. “And you off on that yacht … I can’t take cognizance, Captain. Not under the circumstances.” He glanced up again. Slyness glistened in his eyes. “Of course,” he said, “if you want to cancel your own leave—”
Flandry stood a moment, rigid, staring at the desk-bound man who hated him. Memory trickled back: After I broke off with her, yes, the girl did go a bit wild. She was killed in an accident on Venus, wasn’t she … drunken party flying over the Saw … yes, I seem to’ve heard about it. And Fenross has never even looked at another woman.
He sighed. “Sir, I am reporting myself back on active duty.”
Fenross nodded. “File that with the robot as you leave. Now I’ve got work for you.”
“But Aycharaych—”
“We’ll handle him. I’ve got a more suitable assignment in mind.” Fenross grinned, tossed down his pill and followed it with a cup of water from the desk fountain. “After all, a dashing field agent ought to dash, don’t you think?”
Could it be just the fact that he’s gotten more rank but I’ve had more fun? wondered Flandry. Who knows? Does he himself? He sat down again, refusing to show expression.
Fenross drummed the desk top and stared at a blank wall. His uniform was as severe as regulations permitted — Flandry’s went in the opposite direction — but it still formed an unnecessarily gorgeous base for his tortured red head. “This is under the strictest secrecy,” he began in a rapid, toneless voice. “I have no idea how long we can suppress the news, though. One of our colonies is under siege. Deep within the Imperial sphere.”
Flandry was forced to whistle. “Where? Who?”
“Ever heard of Vixen? Well, I never had either before this. It’s a human-settled planet of an F6 star about a hundred light-years from Sol, somewhat north and clockwise of Aldebaran. Oddball world, but moderately successful as colonies go. You know that region is poor in systems of interest to humans, and very little explored. In effect, Vixen sits in the middle of a desert. Or does it? You’ll wonder when I tell you that a space fleet appeared several weeks ago and demanded that it yield to occupation. The ships were of exotic type, and the race crewing them can’t be identified. But some, at least, spoke pretty good Anglic.”
Flandry sat dead still. His mind threw up facts, so familiar as to be ridiculous, and yet they must now be considered again. The thing which had happened was without precedent.
An interstellar domain can have no definite borders; stars are scattered too thinly, their types too intermingled. And there are too many of them. In very crude approximation, the Terrestrial Empire was a sphere of some 400 light-years diameter, centered on Sol, and contained an estimated four million stars. But of these less than half had even been visited. A bare 100,000 were directly concerned with the Imperium, a few multiples of that number might have some shadowy contact and owe a theoretical allegiance. Consider a single planet; realize that it is a world, as big and varied and strange as this Terra ever was, with as many conflicting elements of race and language and culture among its natives; estimate how much government even one planet requires, and see how quickly a reign over many becomes impossibly huge. Then consider, too, how small a percentage of stars are of any use to a given species (too hot, too cold, too turbulent, too many companions) and, of those, how few will have even one planet where that species is reasonably safe. The Empire becomes tenuous indeed. And its inconceivable extent is still the merest speck in one outlying part of one spiral arm of one galaxy; among a hundred billion or more great suns, those known to any single world are the barest, tiniest handful.
However — attack that far within the sphere? No! Individual ships could sneak between the stars easily enough. But a war fleet could never come a hundred light-years inward from the farthest Imperial bases. The instantaneous “wake” of disturbed space-time, surging from so many vessels, would be certain of detection somewhere along the line. Therefore—
“Those ships were built within our sphere,” said Flandry slowly. “And not too many parsecs from Vixen.”
Fenross sneered. “Your genius dazzles me. As a matter of fact, though, they might have come further than usual, undetected, because so much of the Navy is out at Syrax now. Our interior posts are stripped, some completely deserted. I’ll agree the enemy must base within several parsecs of Vixen. But that doesn’t mean they live there. Their base might be a space station, a rogue planet, or something else we’ll never find; they could have sent their fleet to it a ship at a time, over a period of months.”
Flandry shook his head. “Supply lines. Having occupied Vixen, they’ll need to maintain their garrison till it’s self-sufficient. No, they have a home somewhere in the Imperial sphere, surely in the same quadrant. Which includes only about a million stars! Say, roughly, 100,000 possibilities, some never even catalogued. How many years would it take how many ships to check out 100,000 systems?”
“Yeh. And what would be happening meanwhile?”
“What has?”
“The Vixenites put up a fight. There’s a small naval base on their planet, unmanned at present, but enough of the civilian population knew how to make use of its arsenal. They got couriers away, of course, and Aldebaran Station sent what little help it could. When last heard from, Vixen was under siege. We’re dispatching a task force, but it’ll take time to get there. That wretched Syrax business ties our hands. Reports indicate the aliens haven’t overwhelming strength; we could send enough ships to make mesons of them. But if we withdrew that many from Syrax, they’d come back to find Merseia entrenched in the Cluster.”
“Tie-in?” wondered Flandry.
“Who knows? I’ve got an idea, though, and your assignment will be to investigate it.” Fenross leaned over the desk. His sunken eyes probed at Flandry’s. “We’re all too ready to think of Merseia when anything goes wrong,” he said bleakly. “But after all, they live a long ways off. There’s another alien power right next cloor … and as closely interwoven with Merseia as it is with us.”
“You mean Ymir?” Flandry snorted. “Come now, dear chief, you’re letting your xenophobia run away with you.”
“Consider,” said Fenross. “Somebody, or something, helped those aliens at Vixen build a modern war fleet. They couldn’t have done it alone: we’d have known it if they’d begun exploring stellar space, and knowledge has to precede conquest. Somebody, very familiar with our situation, has briefed the aliens on our language, weapons, territorial layout — the works. Somebody, I’m sure, told them when to attack: right now, when nearly our whole strength is at Syrax. Who? There’s one item. The aliens use a helium-pressure power system like the Ymirites. That’s unmistakable on the detectors. Helium-pressure is all right, but it’s not as convenient as the hydrogen-heavy atom cycle; not if you live under terrestroid conditions, and the aliens very definitely do. The ships, their shape I mean, also have a subtly Ymirite touch. I’ll show you pictures that have arrived with the reports. Those ships look as if they’d been designed by some engineer more used to working with hydrolithium than steel.”
