One can't be too cautious about the people one meets in Tangier. They're all weirdies of one kind or another. Me? Oh, Here Myself By MACK REYNOLDS The Place de France is the town's hub. It marks the end of Boulevard Pasteur, the main drag of the westernized part of down to the Grand Socco and the medina. In a three-minute walk from the Place de France you can go from an ultra-modern, California-like resort to the Baghdad of Harun al-Rashid. It's quite a town, Tangier. King-size sidewalk cafes occupy three of the strategic corners on the Place de France. The Cafe de Paris serves the best draft beer in town, gets all the better custom, and has three shoeshine boys attached to the establishment. You can sit of a sunny morning and read the Paris edition of the New York while getting which comes to about five cents at current exchange. You can sit there, after the paper's read, sip your expresso and watch the people go by. Tangier is possibly the most cosmopolitan city in the world. In native costume you'll see Man, and occasionally a Senegalese and Chinese, Hindus and Turks, Levantines and Filipinos, North both sides of the Curtain. In Tangier you'll find some of the world's poorest and some of the richest. The poorest will try to sell you anything from a shoeshine to their not very lily-white bodies, and the richest will avoid your eyes, afraid you might try to sell them something. In spite of recent changes, the smugglers and black-marketeers, fugitives from justice and international con men, espionage drug addicts, displaced and said, "Hello, Paul. Anything new cooking?" He sank into the chair opposite me and looked around for the waiter. The tables were all crowded and since mine was a face he recognized, he assumed he was welcome to intrude. It was more or less standard procedure at the Cafe de Paris. It wasn't a place to go if you wanted to be alone. Paul said, "How are you, Rupert? Haven't seen you for donkey's years." The waiter came along and Paul ordered a glass of beer. Paul was an easy-going, sallow-faced little man. I vaguely remembered "What's in the newspaper?" he said, disinterestedly. "Pogo and Albert are going to fight a duel," I told him, "and Lil Abner is becoming a rock'n'roll singer." He grunted. "Oh," I said, "the intellectual type." I scanned the front page. "The Russkies have put up another manned satellite." "They have, eh? How big?" "Several times bigger than Paul said, "What ever happened A French girl went by with a Paris. Every pore in place. We both looked after her. "You know, what everybody was seeing a few years ago. It's too bad one of these bloody manned satellites wasn't up then. Maybe they would've seen one." "That's an idea," I said. way. I didn't know Paul very well, but, for that matter, it's comparatively seldom you ever get to know anybody very well in Tangier. Largely, cards are played close to the chest. My beer came and a plate of tapas for us both. Tapas at the Cafe de Paris are apt to be potato salad, a few anchovies, Just to say something, I said, "Where do you think they came from?" And when he looked blank, I added, "The Flying Saucers." He grinned. "From Mars or Venus, or someplace." "Ummmm," I said. "Too bad landed on the Yale football field and said Take me to your cheerleader , or something." Paul yawned and said, "That them. If they were aliens from space, then why not show themselves?" I ate one of the potato chips. It'd been cooked in rancid olive probably sit around here and think of two or three that made sense." Paul was mildly interested. see. You're not eligible for membership until you, well, say until you've developed space flight. Then you're invited into the club. Meanwhile, they send secret missions down from time to time to keep an eye on your progress." Paul grinned at me. "I see you in a neatly tailored gray after her. advanced civilization on, say, "Don't interrupt, please," I said with mock severity. "This air. Isn't that what we'd do, in a few million years, if Earth lost its water and air?" "I suppose so," he said. "Anyway, what about them?" "Well, they observe how man is going through a scientific population boom. A boom, period. Any day now he's going to have practical space ships. Meanwhile, he's also got the H-Bomb and the way he beats the drums on both sides of the Curtain, he's get away with it." Paul said, "I got it. So they're scared and are keeping an eye on us. That's an old one. I've read "I got a better one. How's and revolutions, and greed for giving us a bad time here on don't know where we're going or how we're going to get there." I finished my beer and clapped my hands for Mouley. "How do you mean, where we're going ?" in the world today. They're trying to industrialize, modernize, catch up with the advanced countries. Look at Egypt, and Israel, and India and China, and Yugoslavia and Brazil, and all the rest. Trying to drag themselves up to the level of the advanced at the so-called advanced countries. Up to their bottoms in climbing crime and suicide rates, the loony-bins full of the balmy, unemployed, threat of war, spending all their money on armaments it. Why, a man from Mars would be fascinated, like." Mouley came shuffling up in his babouche slippers and we both ordered another schooner of beer. Paul said seriously, "You brick wall. Where are they, these observers, or scholars, or spies or whatever they are? Sooner or later we'd nab one of them. You know, Scotland Yard, or the F.B.I., or Russia's secret in police, counter-espionage outfits and security agents that an alien would slip up in time, no matter how much he'd been trained. Sooner or later, he'd slip up, and they'd nab him." I shook my head. "Not necessarily. The first time I ever considered this possibility, it seemed to me that such an alien would base himself in London or New York. Somewhere where he could use the libraries for research, center of things. But now I don't think so. I think he'd be right here in Tangier." "Why Tangier?" "It's the one town in the world where anything goes. Nobody gives a damn about you or your affairs. For instance, I've known you a year or more now, and I you make your living." "That's right," Paul admitted. could care less. Where are you from, Rupert?" you mean?" "I felt your mind probe back a few minutes ago when I was talking about Scotland Yard or in, neither of us is humanoid. Where are you really from, Rupert?" about you?" "Deneb," he told me, shaking. We had a laugh and ordered another beer. "What're you doing here on Earth?" I asked him. "Researching for one of our meat trusts. We're protein quite a delicacy. How about you?" "Scouting the place for thrill tourists. My job is to go around to these backward cultures and help stir up inter-tribal, or international, conflicts—all according to how advanced they are. Then our tourists come in—well shielded, of course—and get their kicks watching it." Paul frowned. "That sort of
