that murderous little beast out of here! Or isn't murder against the local laws?" "The Stortulian will be duly punished," replied the leader of the exhibitionist urge. "Send them in one at a time," I told Stebbins. I ducked into the 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. I throttled my exclamation of surprise, concealing it behind a quick cough. "Let me have that again, please?" "All I ask is a contract, Corrigan. It isn't much. I'll be a big attraction. I'll—" He glowered at me reproachfully for a moment, stood up and sauntered to the door. "I thought you were a man of acumen, Corrigan. Well, think it over. Maybe you'll regret your hastiness. I'll be back to give you another chance." Kallerian. The Kallerian was the sixth applicant that afternoon. I immediately to a contract." "Sit down, Freeman Heraal. I like to make my own decisions, thanks." "You will grant me a contract!" "Will you please sit down?" He said sulkily, "I will remain standing." 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. The beady little eyes flashed like beacons in the fur. "Yes, you have four representatives—of the Clan Verdrokh! None of the Clan Gursdrinn! For three years, I have waited for a chance to avenge this insult to the noble Clan Gursdrinn!" At the key-word avenge , 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!" "Threats will get you nowhere, Freeman Heraal. I give you my word I'll get in touch with you as soon as our organization has room for another Kallerian. And now, please, there are many applicants waiting—" Ludlow appeared simultaneously from the two doors at right and left. They surrounded the towering Kallerian and sweet-talkingly led him away. He wasn't minded to quarrel physically, or he could have knocked but he kept up a growling flow of invective and threats until he was out in the hall. "Please, please," squeaked the little alien pitifully. "I must see you, honored sir!" to Ghryne for the miserable purpose of obtaining an interview with yourself." I said, "I'd better tell you right at the outset that we're already carrying our full complement of Stortulians. We have both a male and a I glanced down at the inventory chart until I found the Stortulian "She lied! She left my burrow because she longed to see the splendors of Earth. And I am alone, bound by our sacred customs never to remarry, 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 heart to me." "I thought the truth would move you." "It did. But in effect you're now asking me to conspire in a fraudulent criminal act. Friend, I can't do it. My reputation means too much to me," I said piously. "Then you will refuse me?" "My heart melts to nothingness for you. But I can't take you to Earth." against her will. And maybe she's happier where she is." The Stortulian seemed to shrivel. His eyelids closed half-way to mask his tears. He turned and shambled slowly to the door, walking like a living dishrag. In a bleak voice, he said, "There is no hope then. All commit suicide on my account. About fifty more applicants were processed without a hitch. Then life started to get complicated again. I had just about begun to forget about the incidents of the Kallerian's "Change your mind about me yet?" "Get out before I have you thrown out." "I don't care what your story is! Get out or—" "—you'll have me thrown out. Okay, okay. Just give me half a second. Corrigan, you're no fool, and neither am I—but that fellow of yours I scowled at him. "Too damn many." "You see? He's incompetent. Suppose you fire him, take me on instead. that I'm not looking for any of those either. Now will you scram or—" with a roar. "Earthman, you have mortally insulted the Clan Gursdrinn!" Sitting with my hands poised near the meshgun trigger, I was ready to let him have it at the first sight of actual violence. Heraal boomed, "You are responsible for what is to happen now. I have "—that your unethical actions have directly contributed to the untimely death of an intelligent life-form," filled in the second of the Ghrynian policemen. "The evidence lies before us," intoned the leader, "in the cadaver "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—" "Failure to deny is admission of guilt. You are guilty, Earthman." 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 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 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—" Stortulian wasn't here to commit suicide, you see. He was out to get you." "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 caused their trouble. In this case, you." I began to chuckle—more of a tension-relieving snicker than a "Don't mention it," Gorb said. I glared at the Ghrynian police. "Well? What are you waiting for? Take
