tourist he himself was pretending to be. But Albert wasn't interested in the sights, sounds or smells, nor did the natives intrigue him. There was only one of them he cared to meet—that slimy doublecrosser called Shifaz who had nearly conned him into a one-way ticket. Albert plowed heedlessly through the crowd, using his superior mass to remove natives from his path. By completely disregarding the code of conduct outlined by the IC travel bureau, he managed to make respectable progress toward the enormous covered area in the center of town that housed the Kazlak, or native marketplace. Shifaz had a stand there where he was employed as a tourist guide. The Zark, meanwhile, was not idle despite the outside interests.

His yellow eyes widened and his hand darted to his girdle and came up with a knife. The nearest tourists fell back in alarm as he hissed malevolently at Albert, "Stand back, Earthman, or I'll let the life out of your scaleless carcass!" "Doublecrosser," Albert said, moving in. One meaty hand closed over the knife hand and wrenched while the other caught Shifaz alongside the head with a smack that
