Extensive research did not uncover any evidence that Gorb stepped forward and put a hand on his chest. "Hold it," the Wazzenazzian said crisply. "The Consulate can't help you. I can." "You?" I said. Gorb grinned rakishly. "Five thousand in cash plus a contract as a I eyed Gorb uncertainly. The Terran Consulate people probably wouldn't giving this slyster a contract might be a risky proposition. Gorb shrugged. "What have I to lose?" packs in the crowds back on Earth. Why not? It's the best of its kind, other species of the universe. The office buzzer sounded. Auchinleck said unctuously, "The first "Your name?" "Lawrence R. Fitzgerald." I throttled my exclamation of surprise, concealing it behind a quick cough. "Let me have that again, please?" "Certainly. My name is Lawrence R. Fitzgerald. The 'R' stands for "Of course, that's not the name you were born with." of his species in the show, but they made good crowd-pleasers, being so plump and cheerful. I passed him along to Auchinleck to sign at anything short of top rate. It was the isolationism of the late 29th century that turned me into 400 feet long and appropriately fearsome to the eye, but I didn't see how we could take one on. They're gentle and likable beings, but their though he was clean and reasonably well dressed, he had a shabby look "I'm a non-terrestrial. My name is Ildwar Gorb, of the planet Wazzenazz XIII." for my sense of humor. Or my generosity." "I've never been within a dozen parsecs of Earth," he said smoothly. "I happen to be a representative of the only Earthlike race that exists anywhere in the Galaxy but on Earth itself. Wazzenazz XIII is a small and little-known planet in the Crab Nebula. Through an evolutionary There was something glib and appealing about this preposterous phony. I guess I recognized a kindred spirit or I would have tossed him out on his ear without another word. Instead I played along. "If you're from such a distant place, how come you speak English so well?" "I'm not speaking. I'm a telepath—not the kind that reads minds, just "Very clever, Mr. Gorb." I grinned at him and shook my head. "You spin a good yarn—but for my money, you're really Sam Jones or Phil Smith from Earth, stranded here and out of cash. You want a free trip back to Earth. No deal. The demand for beings from Wazzenazz XIII is pretty low these days. Zero, in fact. Good-by, Mr. Gorb." I pulled away from his yawning mouth. "Good-by, Mr. Gorb," I repeated. Good-by, Mr. Gorb! a job! But I wasn't buying it, even if I could appreciate his cleverness intellectually. There's no such place as Wazzenazz XIII and there's only one human race in the Galaxy—on Earth. I was going to need some real good reason before I gave a down-and-out grifter a free ticket I didn't know it then, but before the day was out, I would have that reason. And, with it, plenty of trouble on my hands. The first harbinger of woe turned up after lunch in the person of a Kallerian. The Kallerian was the sixth applicant that afternoon. I sometimes useful in dealing with belligerent or disappointed because—" "You will hire me or trouble I will make!" The beady little eyes flashed like beacons in the fur. "Yes, you have avenge , I readied myself to ensnarl the Kallerian in a spume of tanglemesh the instant he went for his blaster, but he I went on, "Please be assured that I'll undo the insult at the earliest "No. You will hire me now." "You will rue! I will take drastic measures!" "Threats will get you nowhere, Freeman Heraal. I give you my word I'll the chance that, by picking a given member of a race, we're insulting "It isn't his turn in line," Stebbins protested. "There are at least fifty ahead of him." "All right," I said tiredly. "As long as he's in here already, I might as well see him. Be more careful next time, Stebbins." "You are not in full understanding of my plight. The female Tiress, "She lied! She left my burrow because she longed to see the splendors must "But—" It isn't, but another of my principles is to refuse to be swayed by coming isn't scientific, I can't in all conscience I?" "Well—" "Of course not." I took advantage of his pathetic upset to steam right along. "Now if you had come in here and simply asked me to sign you up, I might conceivably have done it. But no—you had to go unburden your "I thought the truth would move you." criminal act. Friend, I can't do it. My reputation means too much to "Then you will refuse me?" scientific interest, and the World Government will deport the against her will. And maybe she's happier where she is." He spoke in a drab monotone that almost, but not quite, had me weeping. Nine of the fifty were okay. The rest were unacceptable for one reason or another, and they took the bad news quietly enough. The haul for the I had just about begun to forget about the incidents of the Kallerian's outraged pride and the Stortulian's flighty wife when the door opened and the Earthman who called himself Ildwar Gorb of Wazzenazz XIII stepped in. "How did you get in here?" I demanded. "Change your mind about me yet?" "Get out before I have you thrown out." Gorb shrugged. "I figured you hadn't changed your mind, so I've changed my pitch a bit. If you won't believe I'm from Wazzenazz XIII, suppose I tell you that I am your story is! Get out or—" Corrigan, you're no fool, and neither am I—but that fellow of yours "You see? He's incompetent.

He was dressed from head to toe in glittering metalfoil, and instead of his ceremonial blaster, he was wielding dragging helplessly along in his wake, hanging desperately to his belt.

And I shuddered when I remembered that any minute that scrawny little Stortulian was likely to come, to figure out some more effective way of screening myself against crackpots. He's—" "Evidently you don't know as much as you think you do about Stortulian psychology, Corrigan," Gorb said lightly. "Suicide is completely abhorrent to them. When they're troubled, they kill the person who I began to chuckle—more of a tension-relieving snicker than a full-bodied laugh. "Funny," I said. "What is?" asked the self-styled Wazzenazzian. "These aliens. Big blustery Heraal came in with murder in his eye and killed himself "Don't mention it," Gorb said.
