I need hardly explain to my auditors who and what the Naturists are. But to keep the record complete, let me say briefly that this pernicious worldwide conspiracy, founded 50 years ago by the notorious Ali Chaim Pertinuzzi, is engaged in an organized campaign to tear down all the marvelous technical achievements of our civilization. It pretends to believe that we should eat "natural" foods and wear "natural" textiles instead of synthetics, walk instead of ride, teach children the obsolete art of reading (reading what?--the antique books preserved in museums?), make our own music, painting, and sculpture instead of enjoying the exquisite products of perfected machines, open up all parks and the few remaining rural preserves to campers, hunters and fishers (if any specimens worth hunting can be found outside zoos), and what they call "hikers"--in a word, go back to the confused, reactionary world of our ancestors. From this hodgepodge of "principles" it is a natural transition to political and economic subversion. No wonder that the information that Madolin Akkra had been corrupted by this vile outfit sent a chill down Inspector Kazazian's spine. * * * * * It explained a great deal, however. The Naturists profess to oppose our healthy system of sexual experimentation, and Madolin had been a virgin. The weird family situation, and her father's attitude both toward her and toward the Fedpol, aroused suspicion that he too was affiliated with the Naturists, not simply that Madolin had flirted with the outer edges of the treasonable organization, as a "fellow-seeker," without her father's knowledge. Suppose the girl, fundamentally decent and ethically-minded, had revolted against the false doctrine and threatened to betray its advocates? Then she might have been killed to silence her--and what more likely than that, as a piece of brazen defiance, her murdered corpse should have been deposited in the only bit of "natural" ground still remaining in the Newyork area? But how, and by whom? * * * * * The first step, of course, was to fling a dragnet around all known or suspected Naturists in the district. In a series of flying raids they were rounded up; and since there no longer exist those depositories for offenders formerly known as prisons, they were kept incommunicado in the psychiatric wards of the various hospitals. For good measure, Pol Akkra was included. Margret, at 13, was old enough to take care of herself.
