Snap it, now, we've got rush work to do. How good an actor are you?" "That's a silly question." and fall down dead. Number three is to clutch at your side, fall down to it rack-spin film between his fingers, and he knew he was getting a damned sweet picture of everything that was happening. was pretentious enough to be Gunther's quarters. pushed him into a room where Gunther sat. Hathaway looked at him. "So you're Gunther?" he said, calmly. The the controls and keeping his words to himself until just now. "Everything's over with, Mr. Gunther. The Patrol is in the city now and we're capturing your Base. Don't try to fight. We've a thousand men Gunther sat there, blinking at Hathaway, not moving. His thin hands "Impossible!" "I can't respect your opinion, Mr. Gunther." A shouting rose from the Plaza. About fifty of Gunther's men, lounging started yelling. Gunther turned slowly to the huge window in one side he and Marnagan rattled guns with them in their tight hands. Gunther babbled like a child, his voice a shrill dagger in the air. "Get out there, you men! Throw them back! We're outnumbered!" Guns flared. But the Patrol came on. Gunther's men didn't run, Hathaway from filming it. Everything was too wild, hot and angry. Gunther was Gunther raged, and swept a small pistol from his linked corselet. He He didn't know what he was doing until he found the camera in his Then Hathaway took a picture of Gunther slumped at his desk, the chaos that film-contraption!" Overhead, the sun poised black and stars all around it, making it look sick. "If we walk in opposite directions, Click Hathaway, we'd be shaking capture that Gunther lad!" Hathaway went on saying his thoughts: "This is Gunther's work. He's whose dirty face has never been seen, Gunther by name, finally wins fifty minutes to prove you're right. After that—right or wrong—you'll it. As for me—" he twisted his glossy red face. "Keeping alive is me Click nodded. "Gunther knows how you'd hate dying this way, Irish. "Are you telling me? It's man-made. Better than that—it's Gunther! No Gunther'd do anything to—did I say horrors. Progeny from Frankenstein's ARK. Immense crimson beasts with numerous legs and gnashing mandibles, brown-black creatures, some tubular and fat, others like thin white poisonous whips slashing along in the air. Fangs caught starlight white on them. they can't get us in here!" Click's voice gasped it out, "Use your gun." "They got impervious hides. No use. Gahh! And that was a pretty chase, eh, Click?" "Yeah. Sure. and Gunther and— me doing it. Joking in the face of death." "Me father taught me keep laughing and you'll have Irish luck." out. Hathaway petted his camera reluctantly. "What in hell's the use? All this swell film shot. Nobody'll ever see it." "Then," retorted Marnagan, "we'll develop it for our own benefit rescue!" my capture of Gunther, now the least you can do is record peace up arguing about Gunther. Click came back at him: "Gunther drew us down here, sure as Ceres! That gravity change we felt that proves it. Gunther's short on men. So, what's he do he builds an asteroid-base, and drags ships down. Space dispenses with losing valuable, rare ships and a small bunch of men? It's a good front, this damned iron pebble. From it, Gunther strikes unseen ships simply crash, that's all. A subtle hand, with all aces." Marnagan rumbled. "Where is the dirty son, then!" wounds caused at the crackup. If they survive all that—the animals tend to them. It all looks like Nature was responsible. See how subtle Marnagan put the viewer up against the helmet glass, squinted. "Ah, Click. Now, now. This is one lousy film you invented." "Huh?" "It's a strange process'll develop my picture and ignore the asteroid with nothing pretending to be happy in front of nothing . Marnagan scowled. "You sure them beasts don't radiate ultra-violet or infra-red or something that won't come out on film?" "Nuts! Any color we see, the camera sees. We've been fooled." "Hey, where you for teaching Junior Patrolmen how to act in tough spots. First-hand education. Poke another spool of film in that contraption and give me profile a scan. This is lesson number seven: Daniel Walks Into The "Keep me in focus, lad." "All the way, Irish." "What do they say...? Oh, yeah. Action. Lights. Camera!" Right out into the middle of them.... That was the sweetest shot Hathaway ever took. Marnagan and the monsters! Only now it was only Marnagan. "Smile when you say that, Irish." "Sure, and ain't I always smilin'? Ah, Click boy, are them tears in your sweet grey eyes?" "Damn," swore the photographer, embarrassedly. "Why don't they put window-wipers in these helmets?" hunk, I couldn't help—Look, now, about Gunther. Those animals are part of his set-up. Explorers who land here inadvertently, are chased back "But, we've got to Gunther's Base, fight our way in, and get fresh oxy-cannisters." Click attached his camera to his mid-belt. "Gunther probably thinks we're dead by now. Everyone else's been fooled by his playmates they never had a chance to disbelieve them." "If it hadn't been for you taking them pictures, Click—" "Hold tight, hell, let's move. We've got to find where those animals "Come back? How?" in them to a certain point . Psychologically they can both be seen and felt. We only want to see "All right, Click, let's bring 'em back. How do we do it?" Hathaway fought against the mist in his eyes.

I thought Gunther had finished you off. How'd you get past the animals?" Click started running. He switched off his "I tied them pink elephants of Gunther's in neat alphabetical bundles The air-lock door was still wide open when Click reached it, his head let himself down in, quiet and soft. He didn't have a weapon. He didn't you stand right there and die," he said quietly. "That what Gunther "Don't move!" he snapped. "I've got a weapon stronger than yours. One "Ah: ah! Keep your place.

Gunther simply waited for specific cargo ships to intricate, glittering machine, through which strips of colored film with images slid into slots and machine mouths that translated them into thought-emanations. A damned neat piece of genius. "What good would that do?" Hathaway gnawed his lip. "They wouldn't fool the engineers who created them, you nut."
