Where was it all going? A Martian, in line for a bar in the evening, was back again the following morning for another one. And why did the Martians stay just as dirty as ever? The answer was, the Martians stayed as dirty as ever because they weren't using the soap to wash with. They were eating it! It cured the hangover from sugar. Here you'll learn why Mars is called the Red Planet, the part the Mafia plays in her undoing, the rape and rapine that has made this heavenly body the cesspool of the other Martians they are mad at. The going price is one hundred carats of diamonds to kill Then the boys from the more dignified end of the business drop in at the home of the victim and offer to bury him cheap. Two hundred and fifty carats gets a Martian planted in style. Inasmuch as Martians live underground, burying is done in reverse, by tying a rocket to the tail of the deceased and shooting him out into the stratosphere. Mars is presently no problem to Earth, and will not be until we have all its gold and the Martians begin asking us for loans. Meanwhile, Lait and Mortimer say let the gangsters and communists have However, after the sojourner lands, he discovers that Mars is not much different than the planet he left indeed, men are pretty much the subversives—and neither the Martian Committee for the Investigation of Crime and Vice, nor the Un-Martian Activities Committee, can dent it more than the Kefauver Committee did on Earth, which is practically The Mafia sent a couple of front men to explore the desert. Somewhere . Zorkle is a Martian medicinal distillation, made from the milk of the schznoogle Mars. Considerable dissension arose over the bookmaking facilities, when it was learned that the radioactive surface of the planet made it Only chumps bring babes with them to Mars. The temperature is a little colder there than on Earth and the air a little thinner. So Terra for nothing? Martian women are bags, so perhaps you had better disregard the Earthmen looked like Martians do now, which seems to indicate that Martians, as well as Men, have their ups and downs. The citizens of the planet are apparently about halfway down the toboggan. They wear clothes, but they're not handstitched. Their losing country is forced to take the wives of the visitors, which is a twist not yet thought of on Earth. Martian language is unlike anything ever heard below. It would baffle colonies in every land and clime, has a universal language. Knives and brass knucks are understood everywhere. The Martian lingo seems to be somewhat similar to Chinese. It's not what they say, but how they say it. For instance, a stunning effect on the gent on the receiving end because of the lesser gravity. On the other hand, the Martian death ray guns were not fatal to the toughs from Earth anyone who can live through St. Valentine's Day in Martians in for a fifty-fifty partnership, which means they actually gave them one per cent, which is generous at that. Never having had the great advantages of a New Deal, the Martians are still backward and use gold as a means of exchange. With no Harvard bigdomes to tell them gold is a thing of the past, the yellow metal circulates there as freely and easily as we once kicked pennies around before they became extinct here. The Mafistas quickly set the Martians right about the futility of gold. They eagerly turned it over to the Earthmen in exchange for whose brats made mudpies of gold dust. The discovery came as an accident. The first Earthman to be eliminated on Mars was a two-bit hood from North Clark Street who sold a five-cent Hershey bar with almonds to a Martian for a gold piece worth 94 bucks. that this was the first time it had ever been tasted by a Martian that it acts on them like junk does on an Earthman. They further discovered that the chief source of Martian diet is—believe it or not—poppy seed, hemp and coca leaf, and that the alkaloids thereof: opium, hasheesh and cocaine have not the slightest Poppies grow everywhere, huge russet poppies, ten times as large as those on Earth and 100 times as deadly. It is these poppies which have colored the planet red. Martians are strictly vegetarian: they bake, fry and stew these flowers and weeds and eat them raw with a goo made from fungus and called szchmortz which passes for a salad dressing. Though the Martians were absolutely impervious to the narcotic qualities of the aforementioned flora, they got higher than Mars on small doses of sugar. So the Mafia was in business. The Martians sniffed granulated sugar, Martians higher even than sugar, and brought larger and quicker returns. selling it for its weight in rubies on Mars, a hood is always a hood. They've been cutting dope with sugar for years on Earth, so they with on Mars? Simple. With heroin, of course, which is worthless there. : Until the arrival of the Earthmen, there were no illicit sexual relations on the planet. In fact, no Martian in his right mind would have relations with the native crop of females, and they in turn felt the same way about the males. Laws had to be passed requiring all Martians. Especially smelled. They smelled worse than Texas yahoos just off a cow farm. This proved embarrassing, to say the least, to the procurers. In our other Confidential essays we told you how the Mafia employs part for the delay in putting it on the market down here) and ship it to Mars to deodorize the populace there. After which the ladies of the evening got off their feet and went back to work. : Until the arrival of the Mafia, gambling on Mars was It is a dogma that Mars has no oxygen. Baloney. While it is true that there is considerably less than on Earth in the surface atmosphere, the air underground, in caves, valleys and tunnels, has plenty to support life lavishly, though why Martians want to live after they look at each other we cannot tell you, even confidential. For this reason Martian cities are built underground, and travel between them is carried on through a complicated system of subways predating the New York IRT line by several thousand centuries, though before they went "legitimate" and were constantly on the lam and hiding out. So the Mafia put the Martians to work building a town. There are no building materials on the planet, but the Martians are adept at making gold dust hold together with diamond rivets. The result of their of one of the lawyers, so there was no need to build a jail in this model city. The only ones who ever get arrested, anyway, are the Martians, and they soon discovered that the coppers from Terra would look the other way for a bucket full of gold. Until the arrival of the Earthmen, the Martians were, as stated, peaceful, and even now crime is practically unknown among them. The chief problem, however, is to keep them in line on pay nights, when they go on sugar binges. Chocolate bars are as common on Mars as saloons are on Broadway, and it is not unusual to see "gone" Martians getting heaved out of these The gangsters had not been on Mars long before they heard rumors about apparatus sent to Mars from Soviet Russia. This cell was so active that Commies had taken over almost half the planet before the arrival of the Mafia, with their domain extending cells in every quarter of the planet, and many of the top officials of the four Martian governments were either secretly party members or you have nothing to lose but your wives." Comes the revolution, they were told, and all Martians could remain bachelors. It is no wonder the Communists made such inroads. The planet became known as "The Red Red Planet." And on Earth, the Mafia, which is another international conspiracy And so when the gangsters heard there were Communist cells on Mars, And so it was on Mars.
