RETIEF OF THE RED-TAPE MOUNTAIN Retief knew the importance of sealed take certain action." He swung back to face Retief. "I'm sending you in to handle the situation, Retief—under sealed orders." He picked He passed the buff envelope across to Retief. "Hold on," said Retief. "I've got to get down. They won't shoot at you." punching keys on the console. Retief reached out, caught his wrist. The pilot plunged against the restraint, swung a punch that Retief Retief crawled into the narrow cockpit of the skiff, glanced over the controls. The pilot ducked out of sight, came back, handed Retief a Retief felt sweat pop out on his forehead. The red blip meant heavy the missile, and Retief was slammed violently against the restraining shocks, a final bone-shaking concussion, then stillness, broken by the ping of hot metal contracting. Coughing, Retief disengaged himself from the shock-webbing. He beat out sparks in his lap, groped underfoot for the hatch and wrenched it open. A wave of hot jungle air struck him. He lowered himself to a bed of shattered foliage, got to his feet ... and dropped flat as a bullet whined past his ear. Retief edged back around the trunk, eased down behind a fallen log. A stocky man in grimy leather shirt and shorts appeared, moving cautiously, a pistol in his hand. As he passed, Retief rose, leaped the log and tackled him. They went down together. The stranger gave one short yell, then struggled in silence. Retief flipped him onto his back, raised a fist— "Hey!" the settler yelled. "You're as human as I am!" "Maybe I'll look better after a shave," said Retief. "What's the idea mistake. Lemuel's a tough man to explain something to." "I'm—" "Keep your head down. These damn Flap-jacks have got some wicked hand weapons. Come on...." He moved off silently on all fours. Retief Retief looked down at the charred, torn and sweat-soaked powder-blue Potter was on his way, loping off up a gentle slope. Retief pulled off Retief. "We put out the word back home. We all got relatives on Ivory He eyed Retief. Retief got to his feet. "I think I should explain—" Lemuel stared at Retief. "You givin' me orders...?" Retief's left fist shot out, smacked Lemuel's face dead center. He stumbled back, blood starting from his nose the pistol fired into the dirt as he dropped it. He caught himself, jumped for Retief ... and met a straight right that snapped him onto his back: out cold. "Wow!" said Potter. "The stranger took Lem ... in two punches!" peered past the fire— With a swift lunge he seized up the bucket of drinking water, dashed it over the fire, threw himself flat. He heard the others hit the dirt a split second behind him. "Later. Sit tight and keep your eyes open." Retief took a bearing on a Retief rolled aside, then lunged, threw his weight on the flopping Flap-jack—a yard square, three inches thick at the center and all muscle. The ray-like creature heaved up, curled backward, its edge rippling, to stand on the flattened rim of its encircling sphincter. It scrabbled with prehensile fringe-tentacles for a grip on Retief's shoulders. He wrapped his arms around the alien and struggled to his feet. The thing was heavy. A hundred pounds at least. Fighting as it was, it seemed more like five hundred. The Flap-jack reversed its tactics, went limp. Retief grabbed, felt a thumb slip into an orifice— The alien went wild. Retief hung on, dug the thumb in deeper. "Sorry, fellow," he muttered between clenched teeth. "Eye-gouging isn't gentlemanly, but it's effective...." The Flap-jack fell still, only its fringes rippling slowly. Retief the alien gave a tentative jerk the thumb dug in. "Now we understand each other," said Retief. "Take me to your leader." A penetrating beam of red light struck Retief in the face, blinked off. He got to his feet. The captive Flap-jack rippled its fringe in an "The word of a gentleman is sufficient." Retief released the alien. It Retief turned. An immense Flap-jack, hung with crimson trappings, "Avoid it?" Retief heard a low humming coming from the speaker in the "I'm Retief." Hoshick waited expectantly, "... of the Mountain of Red "Take place, Retief," said Hoshick. "I hope you won't find our rude earth-grubbing form, but we were soon disabused of that notion." He raised a tube, manipulating it deftly with his fringe tentacles. Retief "Oh, by all means," Retief said. "No atomics. As you pointed out, "Still, now that we have commenced so merrily with weapons...." Hoshick "Sir!" said Retief sternly. "You forget yourself. I, Retief of the Red "New?" cried Hoshick. "My dear Retief, what a pleasant surprise! I'm retainers were grouped behind him. "I fear I must lay aside the translator now, Retief," said Hoshick. He sighed and rippled his fringe tentacles. "My spawn-fellows will never credit this. Such a curious turn fashion has taken. How much Biting, gouging, stomping, kneeing and of course choking, as well as the usual punching, shoving and kicking." endo-skeletons I fear I shall be at a disadvantage." "Of course," Retief said, "if you'd prefer a more plebeian type of contest...." "By no means. But perhaps we could rule out tentacle-twisting, just to even it." "Very well. Shall we begin?" With a rush Hoshick threw himself at Retief, who ducked, whirled, and leaped on the Flap-jack's back ... and felt himself flipped clear by a mighty ripple of the alien's slab-like body. Retief rolled aside as Hoshick turned on him he jumped to his feet and threw a right hay-maker to Hoshick's mid-section. The alien whipped his left fringe around in an arc that connected with Retief's jaw, sent him spinning onto his back ... and Hoshick's weight struck him. Retief twisted, tried to roll. The flat body of the alien blanketed him. He worked an arm free, drumming blows on the leathery back. Hoshick nestled closer. Retief's air was running out. He heaved up against the smothering and probed. The Flap-jack recoiled. Retief held fast, probed deeper, groping with the other hand. If the alien were bilaterally symmetrical there would There were. Retief dug in and the Flap-jack writhed, pulled away. Retief held on, scrambled to his feet, threw his weight against the alien and fell on top of him, still gouging. Hoshick rippled his fringe wildly, flopped in terror, then went limp. Retief relaxed, released his hold and got to his feet, breathing hard. Hoshick humped himself over onto his ventral side, lifted and moved "Enough!" Hoshick roared, so loudly that the translator bounced on his Hoshick curled his back in attention. "Retief, you're quite serious? Hoshick rippled his fringes ecstatically. "Once again you have outdone
