trussing Qorn up for me." "But we must select a leader!" "That won't be necessary, boys. I'm your new leader." "As I see it," Retief said, dribbling cigar ashes into an empty wine glass, "you Qornt like to be warriors, but you don't particularly like to fight." "We don't mind a little fighting—within reason. And, of course, as Qornt, we're expected to die in battle. But what I say is, why rush "I have a suggestion," Magnan said. "Why not turn the reins of government over to the Verpp? They seem a level-headed group." "What good would that do? Qornt are Qornt. It seems there's always one among us who's a slave to instinct—and, naturally, we have to follow "We have been served, gentlemen, with nothing less than an Ultimatum!" "Why not do it another way?" Magnan offered. "Now, I'd like to suggest community singing—" "If we gave up fighting, we might live too long. Then what would happen?" "When estivating time comes there'd be no burrows for us. Anyway, with "We're up against something new, gentlemen! I've considered every hypothesis from cloaks of invisibility to time travel! The fact is—the Qornt fleets are indetectible!" The Military Attache pulled at his lower lip. "In that case, we can't "You mean Slun and Zubb—the mild-natured naturalists—will become warmongers like Qorn?" "Very likely. 'The milder the Verpp, the wilder the Qorn,' as the old into Verpp—" "Hmmmm. That's a good question. So far, none have survived Qornthood." "Have you thought of forsaking your warlike ways?" Magnan asked. "What about taking up sheepherding and regular church attendance?" "What do Qornt turn into?" Retief asked. sit around roaring fires and drink and tell lies and then go dashing off to enjoy a brisk affray and some leisurely looting afterward. But we prefer a nice numerical advantage. Not this business of tackling you well rounded and decisive course for meeting this threat. Any "No! No begging," the Economic Officer objected. "I'd say a calm, dignified, aggressive withdrawal—as soon as possible." "We don't want to give them the idea we spook easily," the Military Attache said. "Let's delay the withdrawal—say, until tomorrow." Qornt we have to satisfy our drive to action." "But Mr. Retief is your leader now. He won't let you!" "Only a dead Qornt stays home when Attack day comes. And even if he orders us all to cut our own throats, there are still the other Centers—all with their own leaders. No, gentlemen, the Invasion is definitely on." "Why don't you go invade somebody else?" Magnan suggested. "I could name some very attractive prospects—outside my sector, of course." "Afraid? Good lord, no, ha ha. It's just that I'm afraid I may lose my head and do something rash if I go." "Nonsense! A diplomat is immune to heroic impulses. Take Retief along. No dawdling, now! I want you on the way in two hours. Notify the transport pool at once. Now get going!" them." "Those undoubtedly are the most bloodthirsty, aggressive, merciless countenances it has ever been my misfortune to encounter," Magnan said. "Here, no signalling!" Magnan snapped, looking around. "That would be the invasion of Smorbrod," Magnan said. "And unless we hurry, Retief, we're likely to be caught there with the last of the evacuees!" "And the Qornt are responsible for the ultimatum—unilaterally?" gather you as specimens." "You should have known better than to tackle that fierce-looking have issued an ultimatum to the Corps Diplomatique Terrestrienne—who "I'm not at all sure we're going about this in the right way," Magnan puffed, trotting at Retief's side. "These fellows Zubb and Slun—Oh, they seem affable enough, but how can we be sure we're not being led "We can't." plotting mischief." "Threaten them with violence, Mr Magnan. They're scared of you." "When will the feast be over?" Magnan called hoarsely. scheduled an invasion for next month." sort without reference to the wishes of the majority?" "Oh, the majority of the Qornt favor the move, I imagine." "These few hotheads are permitted to embroil the planet in war?" "Oh, they don't embroil the planet in war. They merely—" "Retief, this is fantastic! I've heard of iron-fisted military cliques before, but this is madness!" "Don't mistake me. We Qornt like a military life. It's great sport to you may goad him to a frenzy." "By no means," Zubb whistled. "I much prefer to observe the frenzy of the Qornt when presented with the news that two peaceful Verpp have been assaulted and kidnapped by bullying interlopers. If there's anything that annoys the Qornt, it's Qornt-like behavior in others. Now step along, please." "Rest assured, this will be reported!" "I doubt it." "You'll face the wrath of Enlightened Galactic Opinion!" "Not here, you're not!" Qorn trumpeted. "Want peace, do you? Well, I don't want peace! I've had a surfeit of peace these last two centuries! I want action! Loot! Adventure! Glory!" He turned to look down the table. "How about it, fellows? It's war to the knife, eh?" There was a momentary silence from all sides. eyes. "Silence!" Qorn hooted. "No use your talking to my loyal lieutenants anyway," he added. "They do whatever I convince them they ought to do." "But I'm sure that on more mature consideration—" "Now," Qorn said, lolling back in his chair, glass in hand. "There's a bit of sport to be had here, lads. What shall we do with them?" "Let them go," the blue and flame Qornt said glumly. "You can do better than that," Qorn hooted. "Now here's a suggestion: reasonable scrap," Qorn said judiciously. "I have a feeling that they're thinking of giving up without a struggle." "Oh, I doubt that," the blue-and-flame Qornt said. "Why should they?" Qorn rolled an eye at Retief and another at Magnan. "Take these two," he hooted. "I'll wager they came here to negotiate a surrender!" "Well," Magnan started. "Hold it, Mr. Magnan," Retief said. "I'll tell him." assure you, it's useless. We Qornt you. Now, as to the evacuation of Roolit I—" Qorn slammed his fist down on the table. "I don't care what they are!" he honked. "Evacuate, hell! I can field eighty-five combat-ready ships!" "And we can englobe every one of them with a thousand Peace Enforcers "That's all right. They don't have one." "But—" "We'll take you on!" Qorn French-horned. "We're the Qorn! We glory in rest of the boys would listen to reason—" "Over my dead body!" "Enough! Let me at the upstart!"
