"Listen to me, miss," he snapped earnestly, when she tried to draw away. "Don't talk by radio. That ship belongs to the Saylor brothers! Oh, Lord, that this should happen! Somewhere along the line, we've been double-crossed. Those boys are after this asteroid too, and they won't hesitate to pull any rough stuff. We're in this together, understand? We got to back each other up." The girl nodded dumbly. Suddenly she seemed to be frightened. "It's--it's very important that this--this asteroid stay right where it is," she said huskily. "What--what will they do?" * * * * * Bob Parker didn't answer. The big ship had landed, and little blue sparks crackled between the hull and the asteroid as the magnetic clamps took hold. A few seconds later, the airlocks swung down, and five men let themselves down to the asteroid's surface and stood surveying the three who faced them. The two men in the lead stood with their hands on their hips; their darkish, twin faces were grinning broadly. "A pleasure," drawled Wally Saylor, looking at the girl. "What do you think of this situation Billy?" "It's obvious," drawled Billy Saylor, rocking back and forth on his heels, "that Bob Parker and company have double-crossed us. We'll have to take steps." The three men behind the Saylor twins broke into rough, chuckling laughter. Bob Parker's gorge rose. "Scram," he said coldly. "We've got an ethergram direct from Andrew S. Burnside ordering this asteroid." "So have we," Wally Saylor smiled--and his smile remained fixed, dangerous. He started moving forward, and the three men in back came abreast, forming a semi-circle which slowly closed in. Bob Parker gave back a step, as he saw their intentions. "We got here first," he snapped harshly. "Try any funny stuff and we'll report you to the Interplanetary Commission!" It was Bob Parker's misfortune that he didn't carry a weapon. Each of these men carried one or more, plainly visible. But he was thinking of the girl's spasticizer--a paralyzing weapon. He took a hair-brained chance, jerked the spasticizer from the girl's holster and yelled at Queazy. Queazy got the idea, urged his immense body into motion. He hurled straight at Billy Saylor, lifted him straight off the asteroid and threw him away, into space. He yelled with triumph. At the same time, the spasticizer Bob held was shot cleanly out of his hand by Wally Saylor. Bob roared, started toward Wally Saylor, knocked the smoking gun from his hand with a sweeping arm. Then something crushing seemed to hit him in the stomach, grabbing at his solar plexus. He doubled up, gurgling with agony. He fell over on his back, and his boots were wrenched loose from their magnetic grip. Vaguely, before the flickering points of light in his brain subsided to complete darkness, he heard the girl's scream of rage--then a scream of pain. What had happened to Queazy he didn't know. He felt so horribly sick, he didn't care. Then--lights out.
