question:  What hadn't been smuggled out of Mars?
context: [Transcriber's Note: This etext was produced from Planet Stories Fall 1954. It just ain't big enough for a gent of scope and talent; and the day the Solar System Customs caught me red-handed smuggling Kooleen crystals in from Mars, I knew I was in that corner, and sewed up tight. Sure, the crystals are deadly, but I was smuggling them legitimately, in a manner of speaking, for this doctor to experiment with. But—and this was the 'but' that was likely to deprive the System of my activities—even experimenting with them was illegal even if it needed to be done; also, I had promised not to rat on him before taking the job. Jupiter was a death sentence. "You've no doubt heard tales of the strange population of Jupiter," he said. We possess well-authenticated photographs of these inhabitants, and if you are prepared to visit them and in some way worm from them the secret of their anti-gravity field, the government stands ready to issue you a full pardon as well as a substantial monetary reward. That whole Kooleen caper: Had it been just a trap to lead me straight to this? Government men trapping me and then beaming at me. After all, in the pen a man can eat and breathe, and a guard won't reach in and nip off an arm or leg while he's got his back turned. The way that bunch of stuffed shirts in the S.S.C. made a gold-barred chimpanzee out of me has broken my spirit and turned me into an honest trader. "I just made a pass at the Killicut Emeralds, that's all, and got nabbed." "What were you trying to do, start a feud between us and Mars?" Those emeralds were in the inner shrine of the super-sacred, super-secret temple of the cavern-dwelling tribe of Killicuts on Mars—the real aborigines.
