"Give Frank a pug nose like mine," Sadie directed when a plastic surgeon appeared in answer to Mike's summons. "And how about making him cross-eyed, too?" "How about making her tongue-tied?" Frank retorted. After much argument they compromised by altering the shape of Frank's mouth, slanting his eyebrows and pushing back his hairline. Sadie acquired a classic Greek profile; her freckles were eliminated and her hair became glossy black. Skin grafts were implanted on each of their fingertips. "That should serve unless somebody examines your retina patterns," said the surgeon two days later. "Your features can be changed back, in time, but your fingerprints are permanently altered." "Did I ever love _that_?" sighed Sadie when Frank's bandages were removed at last. "You could get a job in Hollywood," he admitted grudgingly as he studied her in turn. "But confound it, I liked those freckles!" They had kept the air waves to Venusport humming during their confinement. There was the usual red tape to break, of course, but news of the power source was so menacing that New Washington finally agreed to the plan for a sub rosa test of strength--the Space Patrol against the Big Shot ship at a spot somewhere between the orbits of Earth and Venus. "Now it's up to us," said Sadie as they packed for their trip north. "How does it feel to have your head in a lion's mouth?" "What if we can't accomplish anything when we get on board?" "Then we're not the hellraisers we think we are.... Of course S.P. can't lick 'em. It'll have to find a way of getting the drop on 'em.... Don't worry. It will only make you lose the rest of your hair." * * * * * Mike accompanied them on the supply plane which bore them toward the Pole. He was in a bad mood. "I shouldn't ought have done it," he groaned. "If they's been a leak.... If Hans gets suspicious about you two, we'll be burned down. Only thing in our favor is that they're desperately short of men up there." The ship's ports were blacked out as she approached her destination. They had no chance to determine the route. Finally they knew that they had landed on water, but when they emerged that they were in a pressurized hangar which had submerged into a huge chamber drilled in solid rock. "Shots?" barked Hans, surveying the prospective recruits when Mike ushered them into the scientist's severely plain office. "No." The commandant squirmed. "They're Incors, but they'd sell their souls to make a stake." "Incors! Always Incors!" The unhealed radium burn which covered the whole side of the huge man's face flamed an angry red. "I need some people up here that I can half-way trust. All these Incors you've been sending me are dangerous. Already I've smashed two of their plans to steal or smash the ship. What's the matter with you Shots? Yellow?" "Now look here, Hans...." "Yellow!" Hans whirled from Mike and glared at Frank.
