reaching for the safe-lock release.... "Don't!" Retief jumped—too late. The door burst inward. A crowd of crested Groaci pressed into the room, Retief exhaled a plume of cigar smoke. "You can't offend the Groaci," Miss Meuhl said sharply. "Consul Whaffle would never have been so rude." "You're making a serious mistake, Shluh," Retief said. Mr. Retief to his quarters in this building—" "Don't be a fool, woman," Retief said. "Don't you see what you're "You think all women are fools, don't you, Mr. Retief?" She turned to never to reopen that wound, Mr. Retief." disapproval as he closed the door. The pale-featured Groacian vibrated his throat-bladder in a distressed bleat. "The specific instructions of the Archivist." The Groacian's voice rose An elaborate one picked out in pinkish paint seemed to indicate the Groacian equivalent of a bar. Retief went in. A Groacian bartender was dispensing clay pots of alcoholic drink from the bar-pit at the center of the room. He looked at Retief and froze in mid-motion, a metal tube poised over a waiting pot. "To enjoy a cooling drink," Retief said in Groacian, squatting down at the edge of the pit. "To sample a true Groacian beverage." "To not enjoy my poor offerings," the Groacian mumbled. "A pain in the digestive sacs to express regret." "To be grappled in by peace-keepers for poisoning of—foreigners." The barkeep looked around for support, found none. The Groaci customers, eyes elsewhere, were drifting away. "The procuring of a cage," a thin voice called from the sidelines. "The displaying of a freak." Retief turned. A tall Groacian vibrated his mandibles in a gesture of contempt. From his bluish throat coloration, it was apparent the creature was drunk. "To choke in your upper sac," the bartender hissed, extending his eyes toward the drunk. "To keep silent, litter-mate of drones." "To swallow your own poison, dispenser of vileness," the drunk whispered. "To find a proper cage for this zoo-piece." He wavered barkeep whispered something, and two customers came up to the drunk, took his arms and helped him to the door. "To get a cage!" the drunk shrilled. "To keep the animals in their own stinking place." "I've changed my mind," Retief said to the bartender. "To be grateful as hell, but to have to hurry off now." He followed the drunk out the door. The other Groaci released him, hurried back inside. Retief looked at the weaving alien. "To begone, freak," the Groacian whispered. "To be pals," Retief said. "To be kind to dumb animals." "To have you hauled away to a stockyard, ill-odored foreign livestock." "To flee before I take a cane to you!" "To have a drink together—" "To not endure such insolence!" The Groacian advanced toward Retief. Retief backed away. "To hold hands," Retief said. "To be palsy-walsy—" The Groacian reached for him, missed. A passer-by stepped around him, head down, scuttled away. Retief backed into the opening to a narrow crossway and offered further verbal familiarities to the drunken local, who followed, furious. Retief backed, rounded a corner into a narrow alley-like passage, deserted, silent ... except for the following Groacian. Retief stepped around him, seized his collar and yanked. The Groacian fell on his back. Retief stood over him. The downed native half-rose Retief put a foot against his chest and pushed. "To not be going anywhere for a few minutes," Retief said. "To stay Two Groaci wearing heavy eye-shields and elaborate crest ornaments indicative of rank rose as Retief entered the room. Neither offered a courteous snap of the mandibles, Retief noted. They were mad, all right. "Never mind that," Retief said. "These gentlemen didn't come here to chief. "One hour ago," The Groacian said, "a Groacian national was brought to hospital suffering from serious contusions. Questioning of this individual revealed that he had been set upon and beaten by a episode! And you—" "Terrible? I understand that a Terrestrial task force stood off Groac "How did they die?" Retief snapped. "Did you murder them, cut their "I see," Retief said. "They died." "What did you do with it? It was too big to just walk off and forget. Where is it?" The two Groacians exchanged looks. "We wish to show our contrition," Fith said. "We will show you the ship." stood, looked at the Groaci. "Let's go," he said. Retief stooped under the heavy timbers shoring the entry to the cavern. A Groacian threw a switch. A weak bluish glow sprang up. Retief walked along the raised wooden catwalk, studying the ship. Empty "How did you get it in here?" Retief asked. "I've seen enough," Retief said. Silently, the Groacians led the way back out through the tunnel and into the late afternoon sunshine. As they climbed the slope to the steam car, Fith came to Retief's side. "We were at fault," Fith said abjectly. "Now we wish only friendship." "The Retief looked grimly at the slender Foreign Office official. "Where is "Where is that ship?" Retief rapped out. "You never learn, do you? Fith spoke to Shluh in rapid Groacian. The police chief gestured to his four armed constables. They moved to ring Retief in. Retief eyed Fith. "Don't try it," he said. "You'll just get yourself in deeper." Fith clacked his mandibles angrily, eye stalks canted aggressively Retief looked at the four policemen. "I see your point," he said. "If you'll listen, you may find out," Retief said. "I have no time the Groaci is to dispose of both of us. We're the only ones who know what happened. Fith almost did the job this afternoon, but I bluffed him out—for the moment." "I'll do nothing of the sort! The Groaci are very fond of me! You ... Johnny-come-lately! Roughneck! Setting out to destroy—" "Blame it on me if it will make you feel any better," Retief said, "but him silently as he closed the door. It was an hour before dawn when Retief keyed the combination to the Retief, rose and snapped on a light, turned to stare. "I got a little dirty. Don't worry about it." Retief went to his desk, "That's right," Retief said calmly. "Now—" "Get that sender going, woman!" Retief snapped. "This is important." Retief reached out and snapped off the communicator. The triumphant Retief went on earnestly, "I've found the missing cruiser." Retief ignored Miss Meuhl's fury as he spoke into the recorder. "Go ahead," Retief said. "Answer it."
