Murray Leinster: The Aliens

Diane strained her ears for possible re-transmission of the Niccola’s signals, which would indicate the Plumie’s willingness to try conversation. But she suddenly raised her hand and pointed to the radar-graph instrument. It repeated the positioning of dots which were stray meteoric matter in the space between worlds in this system. What had been a spot—the Plumie ship—was now a line of dots. Baird pressed the button.

“Radar reporting!” he said curtly. “The Plumie ship is heading for us. I’ll have relative velocity in ten seconds.”

He heard the skipper swear. Ten seconds later the Doppler measurement became possible. It said the Plumie plunged toward the Niccola at miles per second. In half a minute it was tens of miles per second. There was no re-transmission of signals. The Plumie ship had found itself discovered. Apparently it considered itself attacked. It flung itself into a headlong dash for the Niccola .

Time passed—interminable time. The sun flared and flamed and writhed in emptiness. The great gas-giant planet rolled through space in splendid state, its moonlets spinning gracefully about its bulk. The oxygen-atmosphere planet to sunward was visible only as a crescent, but the mottlings on its lighted part changed as it revolved—seas and islands and continents receiving the sunlight as it turned. Meteor swarms, so dense in appearance on a radar screen, yet so tenuous in reality, floated in their appointed orbits with a seeming vast leisure.

The feel of slowness was actually the result of distance. Men have always acted upon things close by. Battles have always been fought within eye-range, anyhow. But it was actually 06 hours 35 minutes ship time before the two spacecraft sighted each other—more than two hours after they plunged toward a rendezvous.

The Plumie ship was a bright golden dot, at first. It decelerated swiftly. In minutes it was a rounded, end-on disk. Then it swerved lightly and presented an elliptical broadside to the Niccola . The Niccola was in full deceleration too, by then. The two ships came very nearly to a stop with relation to each other when they were hardly twenty miles apart—which meant great daring on both sides.

Baird heard the skipper grumbling:

“ Damned cocky! ” He roared suddenly: “ Mr. Baird! How’ve you made out in communicating with them? ”

“Not at all, sir,” said Baird grimly. “They don’t reply.”

He knew from Diane’s expression that there was no sound in the headphones except the frying noise all main-sequence stars give out, and the infrequent thumping noises that come from gas-giant planets’ lower atmospheres, and the Jansky-radiation hiss which comes from everywhere.

The skipper swore. The Plumie ship lay broadside to, less than a score of miles away. It shone in the sunlight. It acted with extraordinary confidence. It was as if it dared the Niccola to open fire.

Taine’s voice came out of a speaker, harsh and angry:

“ Even-numbered tubes prepare to fire on command. ”

Nothing happened. The two ships floated sunward together, neither approaching nor retreating. But with every second, the need for action of some sort increased.

“ Mr. Baird! ” barked the skipper. “ This is ridiculous! There must be some way to communicate! We can’t sit here glaring at each other forever! Raise them! Get some sort of acknowledgment! ”

“I’m trying,” said Baird bitterly, “according to orders!”

But he disagreed with those orders. It was official theory that arithmetic values, repeated in proper order, would be the way to open conversation. The assumption was that any rational creature would grasp the idea that orderly signals were rational attempts to open communication.

But it had occurred to Baird that a Plumie might not see this point. Perception of order is not necessarily perception of information—in fact, quite the contrary. A message is a disturbance of order. A microphone does not transmit a message when it sends an unvarying tone. A message has to be unpredictable or it conveys no message. Orderly clicks, even if overheard, might seem to Plumies the result of methodically operating machinery. A race capable of interstellar flight was not likely to be interested or thrilled by exercises a human child goes through in kindergarten. They simply wouldn’t seem meaningful at all.

But before he could ask permission to attempt to make talk in a more sophisticated fashion, voices exclaimed all over the ship. They came blurringly to the loud-speakers. “ Look at that! ” “ What’s he do— ” “ Spinning like— ” From every place where there was a vision-plate on the Niccola , men watched the Plumie ship and babbled.

This was at 06 hours 50 minutes ship time.

The elliptical golden object darted into swift and eccentric motion. Lacking an object of known size for comparison, there was no scale. The golden ship might have been the size of an autumn leaf, and in fact its maneuvers suggested the heedless tumblings and scurrying of falling foliage. It fluttered in swift turns and somersaults and spinnings. There were weavings like the purposeful feints of boxers not yet come to battle. There were indescribably graceful swoops and loops and curving dashes like some preposterous dance in emptiness.

Taine’s voice crashed out of a speaker:

“ All even-number rockets ,” he barked. “ Fire! ”

The skipper roared a countermand, but too late. The crunching, grunting sound of rockets leaving their launching tubes came before his first syllable was complete. Then there was silence while the skipper gathered breath for a masterpiece of profanity. But Taine snapped:

“ That dance was a sneak-up! The Plumie came four miles nearer while we watched! ”

Baird jerked his eyes from watching the Plumie. He looked at the master radar. It was faintly blurred with the fading lines of past gyrations, but the golden ship was much nearer the Niccola than it had been.

“Radar reporting,” said Baird sickishly. “Mr. Taine is correct. The Plumie ship did approach us while it danced.”

Taine’s voice snarled:

“ Reload even numbers with chemical-explosive war heads. Then remove atomics from odd numbers and replace with chemicals. The range is too short for atomics. ”

Baird felt curiously divided in his own mind. He disliked Taine very much. Taine was arrogant and suspicious and intolerant even on the Niccola . But Taine had been right twice, now. The Plumie ship had crept closer by pure trickery. And it was right to remove atomic war heads from the rockets. They had a pure-blast radius of ten miles. To destroy the Plumie ship within twice that would endanger the Niccola —and leave nothing of the Plumie to examine afterward.

The Plumie ship must have seen the rocket flares, but it continued to dance, coming nearer and ever nearer in seemingly heedless and purposeless plungings and spinnings in star-speckled space. But suddenly there were racing, rushing trails of swirling vapor. Half the Niccola’s port broadside plunged toward the golden ship. The fraction of a second later, the starboard half-dozen chemical-explosive rockets swung furiously around the ship’s hull and streaked after their brothers. They moved in utterly silent, straight-lined, ravening ferocity toward their target. Baird thought irrelevantly of the vapor trails of an atmosphere-liner in the planet’s upper air.

The ruled-line straightness of the first six rockets’ course abruptly broke. One of them veered crazily out of control. It shifted to an almost right-angled course. A second swung wildly to the left. A third and fourth and fifth—The sixth of the first line of rockets made a great, sweeping turn and came hurtling back toward the Niccola . It was like a nightmare. Lunatic, erratic lines of sunlit vapor eeled before the background of all the stars in creation.
