RETIEF OF THE RED-TAPE MOUNTAIN Retief knew the importance of sealed in to handle the situation, Retief—under sealed orders." He picked "Hold on," said Retief. "I've got to get down. They won't shoot at you." The pilot jumped to the lifeboat hatch and cycled it open. "Get in. We're closin' fast. Them birds might take it into their heads to lob one this way...." 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 Retief altered course to the south. The blip followed. Coughing, Retief disengaged himself from the shock-webbing. He beat out sparks in his lap, groped underfoot for the hatch and wrenched it Retief edged back around the trunk, eased down behind a fallen log. As he passed, Retief rose, leaped the log and tackled him. struggled in silence. Retief flipped him onto his back, raised a fist— "Maybe I'll look better after a shave," said Retief. "What's the idea Flap-jack boat looks just like 'em. I took a shot when I saw something move. Didn't know it was a Terrestrial. Who are you? What you doin' here? We're pretty close to the edge of the oases. That's Flap-jack "I'm glad you're a poor shot. That missile was too close for comfort." "Missile, eh? Must be Flap-jack artillery. We got nothing like that." 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 Flap-jack." "I won't, but—" Potter was on his way, loping off up a gentle slope. Retief pulled off "We're damn glad you're here, mister," said a fat man with two revolvers belted across his paunch. "We can use every hand. We're in bad shape. We ran into the Flap-jacks three months ago and we haven't made a smart move since. First, we thought they were a native form we hadn't run into before. Fact is, one of the boys shot one, thinkin' it you know these Embassy stooges." "We heard they were sending some kind of bureaucrat in here to tell us to get out and give the oases to the Flap-jacks," said Swazey. He tightened his mouth. "We're waitin' for him...." "Meanwhile we got reinforcements comin' up, eh, boys?" Bert winked at "Shut up, you damn fool!" a deep voice grated. "Lemuel!" Potter said. "Nobody else could sneak up on us like that." "If I'd a been a Flap-jack I'd of et you alive," the newcomer said, He eyed Retief. Retief got to his feet. "I think I should explain—" Lemuel stared at Retief. "You givin' me orders...?" peered past the fire— With a swift lunge he seized up the bucket of drinking water, dashed it "No," said Retief. "You wait here. I'm going out alone." "Later. Sit tight and keep your eyes open." Retief took a bearing on a of open ground to another shelter. Retief watched. Minutes passed. The right this time.... There was a sudden rasp, like leather against concrete, and a flurry of sand as the Flap-jack charged. 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. 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 relaxed the pressure of his thumb the alien gave a tentative jerk "Now we understand each other," said Retief. "Take me to your leader." Twenty minutes' walk into the desert brought Retief to a low rampart of thorn branches: the Flap-jacks' outer defensive line against Terry forays. It would be as good a place as any to wait for the move by the Flap-jacks. He sat down and eased the weight of his captive off his back, but kept a firm thumb in place. If his analysis of the situation was correct, a Flap-jack picket should be along before too long.... 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 agitated way. Retief tensed his thumb in the eye-socket. "Sit tight," he said. "Don't try to do anything hasty...." His remarks presences drawing closer. Retief tightened his grip on the alien. He could see a dark shape now, looming up almost to his own six-three. It looked like the Flap-jacks came in all sizes. out. Retief cocked his head, frowning. "That's fine," Retief said. "I'm here to arrange a prisoner exchange." "Let me congratulate you," the voice said. 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 Tape," Retief added. "Take place, Retief," said Hoshick. "I hope you won't find our rude couches uncomfortable." Two other large Flap-jacks came into the room, communed silently with Hoshick. "Pray forgive our lack of translating Outside on the starlit sand Retief tossed aside the power pistol, followed it with the leather shirt Swazey had lent him. By the faint light he could just make out the towering figure of the Flap-jack rearing up before him, his trappings gone. A silent rank of Flap-jack retainers were grouped behind him. "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 Retief's air was running out. He heaved up against the smothering skin tomorrow ... if there was a tomorrow. His thumb found the orifice and probed. The Flap-jack recoiled. Retief held fast, probed deeper, groping with the other hand. If the alien were bilaterally symmetrical there would be a set of ready made hand-holds.... 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 Retief relaxed, released his hold and got to his feet, breathing hard. me, Retief," he cried. "This time, in generosity."
