 What was shocking about the Stortulian's return to the interview office later in the day?
It was our first day of recruiting on the planet, and the alien life-forms had lined up for hundreds of feet back from my rented office. My three staff men, Auchinleck, Stebbins and Ludlow, walked shieldwise in front of me. The aliens came in every shape and form, in all colors and textures—and all of them eager for a Corrigan contract. I thought of it privately as MacTavish IV and referred to it publicly as Ghryne. We had saturated MacTavish IV with our promotional poop for a month preceding arrival. J. F. Corrigan will hold interviews in person on Ghryne from Thirdday to Fifthday of Tenmonth. His last visit to the Caledonia Cluster until 2937, so don't miss your chance! "Before we begin, I'll need certain information about—" "I am a being of Regulus II," came the grave, booming reply, even before I had picked up the blank. I'll be required to remain on exhibit no more than one-third of each Terran sidereal day." But just because we needed him didn't mean we had to be extravagant in hiring him. Our outfit has all the ursinoids it needs or is likely to need in the next few decades, and so I got rid of him in a couple of minutes. He was followed by a roly-poly blue-skinned humanoid from Donovan's Planet, four feet high and five hundred pounds heavy. 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 the successful proprietor of Corrigan's Institute, after some years as an impoverished carnival man in the Betelgeuse system. Before then, anyone could visit Earth. At the same time, we had turned away a dozen ursinoids, fifty of the reptilian natives of Ghryne, seven Sirian spiders, and no less than nineteen chlorine-breathing Procyonites wearing gas masks. 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. 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. "Yes, you have four representatives—of the Clan Verdrokh!
 He was motivated to commit murder.
 His depression was building to a suicide attempt.  He had morphed into a larger being.  He was motivated to commit murder.  He was disguising himself as another being.
