He slammed the door and I let my grim expression relax into a smile. This was the best con switch yet--an Earthman posing as an alien to get 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 home. 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 had turned away three more ursinoids, hired a vegetable from Miazan, and said no to a scaly pseudo-armadillo from one of the Delta Worlds. Hardly had the 'dillo scuttled dejectedly out of my office when the Kallerian came striding in, not even waiting for Stebbins to admit him officially. He was big even for his kind--in the neighborhood of nine feet high, and getting on toward a ton. He planted himself firmly on his three 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 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." "As you prefer." My desk has a few concealed features which are sometimes useful in dealing with belligerent or disappointed life-forms. My fingers roamed to the meshgun trigger, just in case of trouble. The Kallerian stood motionless before me. They're hairy creatures, and this one had a coarse, thick mat of blue fur completely covering his body. Two fierce eyes glimmered out through the otherwise dense blanket of fur. He was wearing the kilt, girdle and ceremonial blaster of his warlike race. I said, "You'll have to understand, Freeman Heraal, that it's not our policy to maintain more than a few members of each species at our 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!" * * * * *
