 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 ducked into the office, took my place back of the desk and waited for the procession to begin. 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." 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. But just because we needed him didn't mean we had to be extravagant in hiring him. The next applicant was a beefy ursinoid from Aldebaran IX. 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. After the gate clanged down, a non-terrestrial could only get onto Sol III as a specimen in a scientific collection—in short, as an exhibit in a zoo. 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. It was also my sad duty to nix a Vegan who was negotiating through a Ghrynian agent.
 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.
