RETIEF OF THE RED-TAPE MOUNTAIN by KEITH LAUMER Retief knew the importance of sealed orders—and the need to keep them that way! take certain action." He swung back to face Retief. "I'm sending you in to handle the situation, Retief—under sealed orders." He picked would look very bad in my record, so I shall expect results." He passed the buff envelope across to Retief. "I understood that Adobe was uninhabited," Retief said, "until the Terrestrial settlers arrived." "Apparently, that was an erroneous impression." Passwyn fixed Retief Sector. You need merely implement it. Is that entirely clear?" "Has anyone at Headquarters ever visited Adobe?" "Of course not. They all hate travel. If there are no other questions, "Hold on," said Retief. "I've got to get down. They won't shoot at you." 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 At a combined speed of two miles per second, the skiff flashed past the missile, and Retief was slammed violently against the restraining Coughing, Retief disengaged himself from the shock-webbing. He beat five yards away. A bush quivered, then a low bough dipped. 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— weapons. Come on...." He moved off silently on all fours. Retief "Have to get you some real clothes, though. Those city duds don't stand up on 'Dobe." Retief looked down at the charred, torn and sweat-soaked powder-blue blazer and slacks. "This outfit seemed pretty rough-and-ready back home," he said. "But I "I won't, but—" Potter was on his way, loping off up a gentle slope. Retief pulled off moving into the ring of fire, a tall, broad-faced man in grimy leather. He eyed Retief. Retief got to his feet. "I think I should explain—" Lemuel stared at Retief. "You givin' me orders...?" "No," said Retief. "You wait here. I'm going out alone." "What's the idea...?" "Later. Sit tight and keep your eyes open." Retief took a bearing on a treetop faintly visible against the sky and started forward. Five minutes' stealthy progress brought him to a slight rise of ground. 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 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 "Now we understand each other," said Retief. "Take me to your leader." 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 were falling on deaf ears—or no ears at all—but the thumb spoke as "Awwrrp! Sorry. Is that better?" a clear voice came from the darkness. "That's fine," Retief said. "I'm here to arrange a prisoner exchange." "Ah, yes, of course. Quite equitable. What guarantees do you require?" "The word of a gentleman is sufficient." Retief released the alien. It flopped once, disappeared into the darkness. "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 "I trust you'll find these dishes palatable," said Hoshick. "Our metabolisms are much alike, I believe." Retief tried the food. It had a "Sir!" said Retief sternly. "You forget yourself. I, Retief of the Red Tape Mountain, make an alternate proposal more in keeping with the newest sporting principles." "New?" cried Hoshick. "My dear Retief, what a pleasant surprise! I'm enthralled with novel modes. One gets so out of touch. Do elaborate." rearing up before him, his trappings gone. A silent rank of Flap-jack retainers were grouped behind him. "I fear I must lay aside the translator now, Retief," said Hoshick. I fear I shall be at a disadvantage." "Of course," Retief said, "if you'd prefer a more plebeian type of contest...." 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 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 weight. Nothing budged. It was like burial under a dump-truck-load of concrete. Retief dug in and the Flap-jack writhed, pulled away. Retief held on, Now, if you'd like to take these deserts and raise lichen, we'll promise to stick to the oases and vegetables." Hoshick curled his back in attention. "Retief, you're quite serious? Hoshick rippled his fringes ecstatically. "Once again you have outdone me, Retief," he cried. "This time, in generosity." "We'll talk over the details later. I'm sure we can establish a set of

<question>:
Did Retief follow the sealed orders given him by Passwyn?

<options>:
A Retief was a skilled but unimaginitive diplomat. His boss, Passwyn, provided the highly specific orders because Retief was not very good at improvising. Therefore, we can infer that Retief would have followed the orders meticulously.
B Since Retief was ordered not to open the sealed packet of orders until he reached Adobe, and he left the ship on a skiff  with only a pistol before he ever got to Adobe. Thus, we can infer that he neither read nor followed the orders.
C Retief knew that there would be at least one or two useful ideas in the packet of orders developed by Headquarters, because the writers had all visited Adobe, and could be considered experts on the planet. Thus, we can infer that he read the orders carefully and followed them as best practices.
D From the unexpected way that Retief reached the surface of Adobe and Retief's obvious penchant for impulsive action, we can infer that although the mission goal was met, the meticulous procedures in the orders were not followed.

<answer>:

D
