Math Section was like a tomb. The machines were silent. graceful slow motion against the far wall. "Now why don't you go away, too?" Tommy turned purple. "We've got five months," he said tried to bury himself in his mother's coat collar. An indignant dimension—but the energy differential was the important one." upset the balance, distorted our whole energy pattern. And they knew from the start that the differential was all on their close range Pete could see that the "scales" were actually tiny Grdznth were mammals—"docile, peace-loving mammals," When?" "Any day now. Maybe any minute." Charlie spread his The creature was most incredibly ugly. Great yellow pouches hands helplessly. "Oh, it won't be bad at all. Spike here was wave of horror and revulsion. A lovely place, really. Just a little too cold for Grdznth. They the seat as the Grdznth breathed at him wetly through damp thought Earth was much nicer." The Grdznth nodded sadly. "It's horrible of me, but I just "Oh, dear. I wanted The Grdznth looked at him reproachfully. "The Wives, of course. The climate is so much better, and they mustn't be disturbed, you know." "And I'm told that things have been somewhat unpleasant sticking out his tongue at the Grdznth. the Grdznth was beginning to fade out. rumble rose around him like a wave. He was a Public Relations man to the core—but right now he was off duty. He chuckled to himself, and the passengers avoided him like the could almost smell the desperate tension of the place. He fought his way past scurrying clerks and preoccupied poll-takers ante-room into the plush director's office, bouncing about excitedly, his words tumbling out like a waterfall. He looked as morning. His appointment was for yesterday , remember?" "Check." "To people who don't want to buy them, right?" "Exactly," said Tommy. "Considering some of the movies you've been selling, you should be able to sell anything to anybody, any time, at any price." "Please. Movies are getting Better by the Day." "Yes, I know. And the Grdznth are getting worse by the hour. They're coming through in battalions—a thousand a day! The more Grdznth come through, the more they act as though they own the place. Not nasty or anything—it's that infernal politeness that people hate most, I think. Can't get them mad, can't get them into a fight, but they do anything they please, and go anywhere they please, and if the people don't like it, the Grdznth just go right ahead anyway." Pete pulled at his lip. "Any violence?" the Grdznth a bit—they have personal protective force fields around them, a little point they didn't bother to tell us about. Anybody who tries anything fancy gets thrown like a bolt of lightning hit him. Rumors are getting wild—people saying they can't be killed, that they're just moving in to stay." Pete nodded slowly. "Are they?" "I wish I knew. I mean, for sure. The psych-docs say no. The Grdznth agreed to leave at a specified time, and something they've been known to be wrong." "And the appointed time?" Tommy spread his hands helplessly. "If we knew, you'd still be in L.A. Roughly six months and four days, plus or minus a month for the time differential. That's strictly tentative, according to the math boys. It's a parallel universe, one of several thousand already explored, according to the Grdznth are analogous, and we happen to be analogous to the Grdznth, any day now." Pete's eyes widened. "Nova?" "Apparently. Nobody knows how they predicted it, but they through parallel after parallel trying to find one they can migrate to. They found one, sort of a desperation choice. It's cold and arid and full of impassable mountain chains. With an uphill fight they can make it support a fraction of their population." system for getting a good strong Grdznth population on here for gestating Grdznth, even better than at home. So they came begging for permission to stop here, on the way through, to rest and parturiate." it just doesn't wash. If the Grdznth are so unpopular with the Pete, with Tommy beaming over his shoulder. "The Grdznth can cross through. They've been able to do it for a long time. According to our figuring, this must involve complete control of mass, space and dimension, all three. And time comes into "and how long the Grdznth gestation period will be." Failed!" The Grdznth sitting on the stool looked regretfully from the "How about the 'jolly company' approach?" "Tried it. There's nothing jolly about them. They pop out of nowhere, anywhere. In church, in bedrooms, in rush-hour traffic through Lincoln Tunnel—look!" Pete peered out the window at the traffic jam below. Cars A squad of traffic cops were converging angrily on the center of the mess, where a stream of green reptilian figures seemed to be popping out of the street and lumbering through the jammed autos like General Sherman tanks. going to see me now, or aren't you?" "Yes, yes, come right in!" Tommy turned white. "Senator Stokes," he muttered. "I'd completely forgotten—" something." "Do something! You think I'm a magician? I can just make them vanish? What do you want me to do?" The senator raised his eyebrows. "You needn't shout, Mr. "We can have prelims six hours after the PR-blast. Pete, if you have an idea, tell us!" they aren't lovable. They aren't even passably attractive. for all the little Grdznth to arrive, and nobody's given them a The color was back in Tommy's cheeks, and the senator was forgotten as a dozen intercom switches began snapping. "We'll Grdznth are lovable?" the people anything you want. If we're going to get across the sanctity of Grdznth motherhood, my friend, anything goes." The planning revealed the mark of genius. Nothing night. Copy rolled by the ream from Tommy's office, refined copy, hypersensitively edited copy, finding its way into the light of day through devious channels. Three days later a Grdznth miscarriage threatened, and was averted. It was only a page 4 item, but it was a beginning. Determined movements to expel the Grdznth faltered, trembled with indecision. The Grdznth were ugly, they frightened a trifle overbearing in their insufferable Not even expectant Grdznth mothers. In the Public Relations Bureau building, machines worked on into the night. As questionnaires came back, spot candid stomach pains. "Fine," said Tommy. "Make a guess." "Give us three hours," said Analysis. "You've got thirty minutes. Get going." the room in an overflow of nervous energy. "I can see it now. Open shafts instead of elevators. A quick hop to Honolulu for an afternoon on the beach, and back in time for supper. A what the Grdznth are giving us, they'll welcome them with open arms." "Hmmm," said Pete. "Well, why won't they? The people just didn't trust us, that the Grdznth girls to gestate. But what are we hearing from nothing except a whole lot of Grdznth and more coming the Grdznth Analysis was a shambles. Paper and tape piled knee-deep on the floor. The machines clattered wildly, coughing out see some baby Grdznth at the end of it all." There was dead silence in the room. "Baby Grdznth,"
