"I see they are," grimly. "I'm right over you now, 'way up. Been locating their primary intake. They've got a dozen ships around it, and have guards posted all along the corridors leading to it; and _those guards are wearing masks!_ They're clever birds, all right, those amphibians--they know what they got back there and how they got it. That changes things, girl! If we use gas here we won't stand a chance in the world of getting old Bradley. Stand by to jump when I open that door!" "Hurry, dear! They are coming out here after me!" "Sure they are." Costigan had already seen the two Nevians swimming out toward Clio's cage, and had hurled his vessel downward in a screaming power dive. "You're too valuable a specimen for them to let you be gassed, but if they can get there before I do they're traveling fast!" He miscalculated slightly, so that instead of coming to a halt at the surface of the liquid medium the speedster struck with a crash that hurled solid masses of water for hundreds of yards. But no ordinary crash could harm that vessel's structure, her gravity controls were not overloaded, and she shot back to the surface; gallant ship and reckless pilot alike unharmed. Costigan trained his key-tube upon the doorway of Clio's cell, then tossed it aside. "Different combinations over here!" he barked. "Got to cut you out--lie down in that far corner!" His hands flashed over the panel, and as Clio fell prone without hesitation or question a heavy beam literally blasted away a large portion of the roof of the structure. The speedster shot into the air and dropped down until she rested upon the tops of opposite walls; walls still glowing, semi-molten. The girl piled a stool upon the table and stood upon it, reached upward, and seized the mailed hands extended downward toward her. Costigan heaved her up into the vessel with a powerful jerk, slammed the door shut, leaped to the controls, and the speedster darted away. "Your armor's in that bundle there. Better put it on, and check your Lewistons and pistols--no telling what kind of jams we'll get into," he snapped, without turning. "Bradley, start talking ... all right, I've got your line. Better get your wet rags ready and get organized generally--every second will count by the time we get there. We're coming so fast that our outer plating's white hot, but it may not be fast enough, at that." "It isn't fast enough, quite," Bradley announced, calmly. "They're coming out after me now." "Don't fight them and probably they won't paralyze you. Keep on talking, so that I can find out where they take you." "No good, Costigan." The voice of the old space-flea did not reveal a sign of emotion as he made his dread announcement. "They have it all figured out. They're not taking any chances at all--they're going to paral...." His voice broke off in the middle of the word.
