Ghrynian cops calmly. "But there is the matter of the dead Kallerian and the fine of—" "—one hundred thousand dollars. I know." I groaned and turned to How cheap?" Gorb grinned rakishly. "Five thousand in cash plus a contract as a specimen with your outfit. In advance, of course. That's a heck of a lot better than forking over a hundred grand, isn't it?" I eyed Gorb uncertainly. The Terran Consulate people probably wouldn't were really serious, and I knew from past experiences that no officials ever worried much about the state of my pocketbook. On the other hand, giving this slyster a contract might be a risky proposition. "Tell you what," I said finally. "You've got yourself a deal—but on a contingency basis. Get me out of this and you'll have five grand and the contract. Otherwise, nothing." Gorb shrugged. "What have I to lose?" The little Regulan was as good as hired. Only the formalities remained. "You understand our terms, Mr. Fitzgerald?" "And the pay will be—ah—$50 Galactic a week, plus expenses and transportation." The spherical creature clapped his hands in joy, three hands clapping accept the terms!" I buzzed for Ludlow and gave him the fast signal that meant we were signing this alien up at half the usual pay, and Ludlow took him into the other office to sign him up. 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. Next came a bedraggled Sirian spider who was more interested in a handout than a job. If there's any species we have a real over-supply a try anyway. He got the gate in half a minute, and he didn't even get the handout he was angling for. I don't approve of begging. upkeep runs into literally tons of fresh meat a day, and not just any old kind of meat either. So we had to do without the Vegan. "One more specimen before lunch," I told Stebbins, "to make it an even Earth. No deal. The demand for beings from Wazzenazz XIII is pretty low these days. Zero, in fact. Good-by, Mr. Gorb." He pointed a finger squarely at me and said, "You're making a big Look here, examine my teeth. Absolutely like human teeth! And—" I pulled away from his yawning mouth. "Good-by, Mr. Gorb," I repeated. "All I ask is a contract, Corrigan. It isn't much. I'll be a big attraction. I'll—" " a job! But I wasn't buying it, even if I could appreciate his cleverness Kallerian. The Kallerian was the sixth applicant that afternoon. I and said no to a scaly pseudo-armadillo from one of the Delta Worlds. Kallerian came striding in, not even waiting for Stebbins to admit him stocky feet, extended his massive arms in a Kallerian greeting-gesture, and growled, "I am Vallo Heraal, Freeman of Kaller IV. You will sign me "You will grant me a contract!" "Will you please sit down?" The Kallerian stood motionless before me. They're hairy creatures, and Institute. And we're not currently in need of any Kallerian males, because—" "You will hire me or trouble I will make!" I opened our inventory chart. I showed him that we were already carrying four Kallerians, and that was more than plenty. , I readied myself to ensnarl the Kallerian in a spume of tanglemesh the instant he went for his blaster, but he didn't move. He bellowed, "I have vowed a vow, Earthman. Take me to Earth, enroll a Gursdrinn, or the consequences will be terrible!" I'm a man of principles, like all straightforward double-dealers, and He glared at me in silence. I went on, "Please be assured that I'll undo the insult at the earliest possible opportunity. It's not feasible for us to hire another Kallerian now, but I'll give preference to the Clan Gursdrinn as soon as a vacancy—" "No. You will hire me now." "It can't be done, Freeman Heraal. We have a budget, and we stick to it." "You will rue! I will take drastic measures!" Kallerian. And now, please, there are many applicants waiting—" They surrounded the towering Kallerian and sweet-talkingly led him "Please, please," squeaked the little alien pitifully. "I must see you, honored sir!" wasn't going to break up a good act just to make an alien squirrel happy—not to mention footing the transportation. I said, "I don't see how we can manage it. The laws are very strict "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 heart to me." About fifty more applicants were processed without a hitch. Then life started to get complicated again. 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 day so far was close to two dozen new life-forms under contract. I had just about begun to forget about the incidents of the Kallerian's outside is . He doesn't know how to handle alien beings. How many times today has a life-form come in here unexpectedly?" I scowled at him. "Too damn many." "You see? He's incompetent. Suppose you fire him, take me on instead. I've been living in the outworlds half my life I know all there is to I've had a hard day. There's been a Kallerian in here who just about The office door crashed open at that point and Heraal, the Kallerian, came thundering in. He was dressed from head to toe in glittering metalfoil, and instead of his ceremonial blaster, he was wielding a sword the length of a human being. Stebbins and Auchinleck came dragging helplessly along in his wake, hanging desperately to his belt. let him have it at the first sight of actual violence. Heraal boomed, "You are responsible for what is to happen now. I have of the unfortunate Kallerian who filed the complaint with us several I'm responsible?" "This is the law. Do you deny that your stubborn refusal to yield to this late life-form's request lies at the root of his sad demise?" "Well, no, but—" Closing my eyes wearily, I tried to wish the whole babbling lot of them away. If I had to, I could pony up the hundred-grand fine, but it was going to put an awful dent in this year's take. And I shuddered when I remembered that any minute that scrawny little Stortulian was likely to come bursting in here to kill himself too. Was it a fine of $100,000 per suicide? At that rate, I could be out of business by nightfall. I was spared further such morbid thoughts by yet another unannounced arrival. and stationed itself limply near the threshold. The three Ghrynian policemen and my three assistants forgot the dead Kallerian for a crackpots. In heart-rending tones, the Stortulian declared, "Life is no longer worth living. My last hope is gone. There is only one thing left for me to do." I was quivering at the thought of another hundred thousand smackers going down the drain. "Stop him, somebody! He's going to kill himself! He's—"
