“We ought to scrape this planet clean of every living thing on it,” muttered Umbo Stetson, section chief of Investigation & Adjustment.

Stetson paced the landing control bridge of his scout cruiser. His footsteps grated on a floor that was the rear wall of the bridge during flight. But now the ship rested on its tail fins—all four hundred glistening red and black meters of it. The open ports of the bridge looked out on the jungle roof of Gienah III some one hundred fifty meters below. A butter yellow sun hung above the horizon, perhaps an hour from setting.

“Clean as an egg!” he barked. He paused in his round of the bridge, glared out the starboard port, spat into the fire-blackened circle that the cruiser’s jets had burned from the jungle.

The I-A section chief was dark-haired, gangling, with large head and big features. He stood in his customary slouch, a stance not improved by sacklike patched blue fatigues. Although on this present operation he rated the flag of a division admiral, his fatigues carried no insignia. There was a general unkempt, straggling look about him.

Lewis Orne, junior I-A field man with a maiden diploma, stood at the opposite port, studying the jungle horizon. Now and then he glanced at the bridge control console, the chronometer above it, the big translite map of their position tilted from the opposite bulkhead. A heavy planet native, he felt vaguely uneasy on this Gienah III with its gravity of only seven-eighths Terran Standard. The surgical scars on his neck where the micro-communications equipment had been inserted itched maddeningly. He scratched.

“Hah!” said Stetson. “Politicians!”

A thin black insect with shell-like wings flew in Orne’s port, settled in his close-cropped red hair. Orne pulled the insect gently from his hair, released it. Again it tried to land in his hair. He ducked. It flew across the bridge, out the port beside Stetson.

There was a thick-muscled, no-fat look to Orne, but something about his blocky, off-center features suggested a clown.

“I’m getting tired of waiting,” he said.

“You’re tired! Hah!”

A breeze rippled the tops of the green ocean below them. Here and there, red and purple flowers jutted from the verdure, bending and nodding like an attentive audience.

“Just look at that blasted jungle!” barked Stetson. “Them and their stupid orders!”

A call bell tinkled on the bridge control console. The red light above the speaker grid began blinking. Stetson shot an angry glance at it. “Yeah, Hal?”

“O.K., Stet. Orders just came through. We use Plan C. ComGO says to brief the field man, and jet out of here.”

“Did you ask them about using another field man?”

Orne looked up attentively.

The speaker said: “Yes. They said we have to use Orne because of the records on the Delphinus.”

“Well then, will they give us more time to brief him?”

“Negative. It’s crash priority. ComGO expects to blast the planet anyway.”

Stetson glared at the grid. “Those fat-headed, lard-bottomed, pig-brained ... POLITICIANS!” He took two deep breaths, subsided. “O.K. Tell them we’ll comply.”

“One more thing, Stet.”

“What now?”

“I’ve got a confirmed contact.”

Instantly, Stetson was poised on the balls of his feet, alert. “Where?”

“About ten kilometers out. Section AAB-6.”

“How many?”

“A mob. You want I should count them?”

“No. What’re they doing?”

“Making a beeline for us. You better get a move on.”

“O.K. Keep us posted.”

“Right.”

Stetson looked across at his junior field man. “Orne, if you decide you want out of this assignment, you just say the word. I’ll back you to the hilt.”

“Why should I want out of my first field assignment?”

“Listen, and find out.” Stetson crossed to a tilt-locker behind the big translite map, hauled out a white coverall uniform with gold insignia, tossed it to Orne. “Get into these while I brief you on the map.”

“But this is an R&R uni—” began Orne.

“Get that uniform on your ugly frame!”

“Yes, sir, Admiral Stetson, sir. Right away, sir. But I thought I was through with old Rediscovery & Reeducation when you drafted me off of Hamal into the I-A ... sir.” He began changing from the I-A blue to the R&R white. Almost as an afterthought, he said: “ ... Sir.”

A wolfish grin cracked Stetson’s big features. “I’m soooooo happy you have the proper attitude of subservience toward authority.”

Orne zipped up the coverall uniform. “Oh, yes, sir ... sir.”

“O.K., Orne, pay attention.” Stetson gestured at the map with its green superimposed grid squares. “Here we are. Here’s that city we flew over on our way down. You’ll head for it as soon as we drop you. The place is big enough that if you hold a course roughly northeast you can’t miss it. We’re—”

Again the call bell rang.

“What is it this time, Hal?” barked Stetson.

“They’ve changed to Plan H, Stet. New orders cut.”

“Five days?”

“That’s all they can give us. ComGO says he can’t keep the information out of High Commissioner Bullone’s hands any longer than that.”

“It’s five days for sure then.”

“Is this the usual R&R foul-up?” asked Orne.

Stetson nodded. “Thanks to Bullone and company! We’re just one jump ahead of catastrophe, but they still pump the bushwah into the Rah & Rah boys back at dear old Uni-Galacta!”

“You’re making light of my revered alma mater,” said Orne. He struck a pose. “We must reunite the lost planets with our centers of culture and industry, and take up the glor-ious onward march of mankind that was so bru-tally—”

“Can it!” snapped Stetson. “We both know we’re going to rediscover one planet too many some day. Rim War all over again. But this is a different breed of fish. It’s not, repeat, not a re-discovery.”

Orne sobered. “Alien?”

“Yes. A-L-I-E-N! A never-before-contacted culture. That language you were force fed on the way over, that’s an alien language. It’s not complete ... all we have off the minis. And we excluded data on the natives because we’ve been hoping to dump this project and nobody the wiser.”

“Holy mazoo!”

“Twenty-six days ago an I-A search ship came through here, had a routine mini-sneaker look at the place. When he combed in his net of sneakers to check the tapes and films, lo and behold, he had a little stranger.”

“One of theirs?”

“No. It was a mini off the Delphinus Rediscovery. The Delphinus has been unreported for eighteen standard months!”

“Did it crack up here?”

“We don’t know. If it did, we haven’t been able to spot it. She was supposed to be way off in the Balandine System by now. But we’ve something else on our minds. It’s the one item that makes me want to blot out this place, and run home with my tail between my legs. We’ve a—”

Again the call bell chimed.

“NOW WHAT?” roared Stetson into the speaker.

“I’ve got a mini over that mob, Stet. They’re talking about us. It’s a definite raiding party.”

“What armament?”

“Too gloomy in that jungle to be sure. The infra beam’s out on this mini. Looks like hard pellet rifles of some kind. Might even be off the Delphinus.”

“Can’t you get closer?”

“Wouldn’t do any good. No light down there, and they’re moving up fast.”

“Keep an eye on them, but don’t ignore the other sectors,” said Stetson.

“You think I was born yesterday?” barked the voice from the grid. The contact broke off with an angry sound.

“One thing I like about the I-A,” said Stetson. “It collects such even-tempered types.” He looked at the white uniform on Orne, wiped a hand across his mouth as though he’d tasted something dirty.

“Why am I wearing this thing?” asked Orne.

“Disguise.”

“But there’s no mustache!”

Stetson smiled without humor. “That’s one of I-A’s answers to those fat-keistered politicians. We’re setting up our own search system to find the planets before they do. We’ve managed to put spies in key places at R&R. Any touchy planets our spies report, we divert the files.”

“Then what?”

“Then we look into them with bright boys like you—disguised as R&R field men.”

“Goody, goody. And what happens if R&R stumbles onto me while I’m down there playing patty cake?”

“We disown you.”

“But you said an I-A ship found this joint.”

“It did. And then one of our spies in R&R intercepted a routine request for an agent-instructor to be assigned here with full equipment. Request signed by a First-Contact officer name of Diston ... of the Delphinus!”

“But the Del—”

“Yeah. Missing. The request was a forgery. Now you see why I’m mostly for rubbing out this place. Who’d dare forge such a thing unless he knew for sure that the original FC officer was missing ... or dead?”

“What the jumped up mazoo are we doing here, Stet?” asked Orne. “Alien calls for a full contact team with all of the—”

“It calls for one planet-buster bomb ... buster—in five days. Unless you give them a white bill in the meantime. High Commissioner Bullone will have word of this planet by then. If Gienah III still exists in five days, can’t you imagine the fun the politicians’ll have with it? Mama mia! We want this planet cleared for contact or dead before then.”

“I don’t like this, Stet.”

“YOU don’t like it!”

“Look,” said Orne. “There must be another way. Why ... when we teamed up with the Alerinoids we gained five hundred years in the physical sciences alone, not to mention the—”

“The Alerinoids didn’t knock over one of our survey ships first.”

“What if the Delphinus just crashed here ... and the locals picked up the pieces?”

“That’s what you’re going in to find out, Orne. But answer me this: If they do have the Delphinus, how long before a tool-using race could be a threat to the galaxy?”

“I saw that city they built, Stet. They could be dug in within six months, and there’d be no—”

“Yeah.”

Orne shook his head. “But think of it: Two civilizations that matured along different lines! Think of all the different ways we’d approach the same problems ... the lever that’d give us for—”

“You sound like a Uni-Galacta lecture! Are you through marching arm in arm into the misty future?”

Orne took a deep breath. “Why’s a freshman like me being tossed into this dish?”

“You’d still be on the Delphinus master lists as an R&R field man. That’s important if you’re masquerading.”

“Am I the only one? I know I’m a recent convert, but—”

“You want out?”

“I didn’t say that. I just want to know why I’m—”

“Because the bigdomes fed a set of requirements into one of their iron monsters. Your card popped out. They were looking for somebody capable, dependable ... and... expendable!”

“Hey!”

“That’s why I’m down here briefing you instead of sitting back on a flagship. I got you into the I-A. Now, you listen carefully: If you push the panic button on this one without cause, I will personally flay you alive. We both know the advantages of an alien contact. But if you get into a hot spot, and call for help, I’ll dive this cruiser into that city to get you out!”

Orne swallowed. “Thanks, Stet. I’m—”

“We’re going to take up a tight orbit. Out beyond us will be five transports full of I-A marines and a Class IX Monitor with one planet-buster. You’re calling the shots, God help you! First, we want to know if they have the Delphinus ... and if so, where it is. Next, we want to know just how warlike these goons are. Can we control them if they’re bloodthirsty. What’s their potential?”

“In five days?”

“Not a second more.”

“What do we know about them?”

“Not much. They look something like an ancient Terran chimpanzee ... only with blue fur. Face is hairless, pink-skinned.” Stetson snapped a switch. The translite map became a screen with a figure frozen on it. “Like that. This is life size.”

“Looks like the missing link they’re always hunting for,” said Orne. “Yeah, but you’ve got a different kind of a missing link.”

“Vertical-slit pupils in their eyes,” said Orne. He studied the figure. It had been caught from the front by a mini-sneaker camera. About five feet tall. The stance was slightly bent forward, long arms. Two vertical nose slits. A flat, lipless mouth. Receding chin. Four-fingered hands. It wore a wide belt from which dangled neat pouches and what looked like tools, although their use was obscure. There appeared to be the tip of a tail protruding from behind one of the squat legs. Behind the creature towered the faery spires of the city they’d observed from the air.

“Tails?” asked Orne.

“Yeah. They’re arboreal. Not a road on the whole planet that we can find. But there are lots of vine lanes through the jungles.” Stetson’s face hardened. “Match that with a city as advanced as that one.”

“Slave culture?”

“Probably.”

“How many cities have they?”

“We’ve found two. This one and another on the other side of the planet. But the other one’s a ruin.”

“A ruin? Why?”

“You tell us. Lots of mysteries here.”

“What’s the planet like?”

“Mostly jungle. There are polar oceans, lakes and rivers. One low mountain chain follows the equatorial belt about two thirds around the planet.”

“But only two cities. Are you sure?”

“Reasonably so. It’d be pretty hard to miss something the size of that thing we flew over. It must be fifty kilometers long and at least ten wide. Swarming with these creatures, too. We’ve got a zone-count estimate that places the city’s population at over thirty million.”

“Whee-ew! Those are tall buildings, too.”

“We don’t know much about this place, Orne. And unless you bring them into the fold, there’ll be nothing but ashes for our archaeologists to pick over.”

“Seems a dirty shame.”

“I agree, but—”

The call bell jangled.

Stetson’s voice sounded tired: “Yeah, Hal?”

“That mob’s only about five kilometers out, Stet. We’ve got Orne’s gear outside in the disguised air sled.”

“We’ll be right down.”

“Why a disguised sled?” asked Orne.

“If they think it’s a ground buggy, they might get careless when you most need an advantage. We could always scoop you out of the air, you know.”

“What’re my chances on this one, Stet?”

Stetson shrugged. “I’m afraid they’re slim. These goons probably have the Delphinus, and they want you just long enough to get your equipment and everything you know.”

“Rough as that, eh?”

“According to our best guess. If you’re not out in five days, we blast.”

Orne cleared his throat.

“Want out?” asked Stetson.

“No.”

“Use the back-door rule, son. Always leave yourself a way out. Now ... let’s check that equipment the surgeons put in your neck.” Stetson put a hand to his throat. His mouth remained closed, but there was a surf-hissing voice in Orne’s ears: “You read me?”

“Sure. I can—”

“No!” hissed the voice. “Touch the mike contact. Keep your mouth closed. Just use your speaking muscles without speaking.”

Orne obeyed.

“O.K.,” said Stetson. “You come in loud and clear.”

“I ought to. I’m right on top of you!”

“There’ll be a relay ship over you all the time,” said Stetson. “Now ... when you’re not touching that mike contact this rig’ll still feed us what you say ... and everything that goes on around you, too. We’ll monitor everything. Got that?”

“Yes.”

Stetson held out his right hand. “Good luck. I meant that about diving in for you. Just say the word.”

“I know the word, too,” said Orne. “HELP!”

Gray mud floor and gloomy aisles between monstrous bluish tree trunks—that was the jungle. Only the barest weak glimmering of sunlight penetrated to the mud. The disguised sled—its para-grav units turned off—lurched and skidded around buttress roots. Its headlights swung in wild arcs across the trunks and down to the mud. Aerial creepers—great looping vines of them—swung down from the towering forest ceiling. A steady drip of condensation spattered the windshield, forcing Orne to use the wipers.

In the bucket seat of the sled’s cab, Orne fought the controls. He was plagued by the vague slow-motion-floating sensation that a heavy planet native always feels in lighter gravity. It gave him an unhappy stomach.

Things skipped through the air around the lurching vehicle: flitting and darting things. Insects came in twin cones, siphoned toward the headlights. There was an endless chittering whistling tok-tok-toking in the gloom beyond the lights.

Stetson’s voice hissed suddenly through the surgically implanted speaker: “How’s it look?”

“Alien.”

“Any sign of that mob?”

“Negative.”

“O.K. We’re taking off.”

Behind Orne, there came a deep rumbling roar that receded as the scout cruiser climbed its jets. All other sounds hung suspended in after-silence, then resumed: the strongest first and then the weakest.

A heavy object suddenly arced through the headlights, swinging on a vine. It disappeared behind a tree. Another. Another. Ghostly shadows with vine pendulums on both sides. Something banged down heavily onto the hood of the sled.
