"All right, line up, you space crawlers!" bawled Coxine. "When I call your name step up to get your share of the haul!"

The pirate captain was seated at the head of a long mess table, an open ledger in front of him. There were stacks of crisp new credit notes at his elbow. He took out his paralo-ray pistols and placed them within easy reach. On either side of him, Wallace and Simms sat, staring at the money with greedy eyes.

Coxine looked at the first name on the ledger.

"Joe Brooks!" he called. "One thousand credits for spotting the liner!"

Brooks grinned and amid cheers walked to the table. Coxine handed him a small stack of notes carelessly and turned back to the ledger.

"Gil Attardi!" he roared. "One thousand credits for working on the boarding crew."

Attardi, a sly, scar-faced man, stepped forward to accept his share. He carried a long, thin knife with an edge so deadly keen that he could and often did shave with it.

Coxine continued his roll call. "Sam Bates! Five hundred credits. Straight share."

Bates stepped forward and glared at Coxine.

"How come I only get five hundred and the others get a thousand?" he snarled. "It ain't my fault I'm stuck on the power deck while you grab all the glory jobs!"

The laughing, excited crowd of men grew silent as the rebellious spaceman faced Coxine.

"You get five hundred credits," snarled Coxine. "Take it or leave it!"

"I want the same as Brooks and Attardi," demanded Bates.

Quicker than the eye could follow, Coxine rose and smashed the man in the face with a giant fist. Bates dropped to the deck like a stone. Coxine glared at the rest of the crew.

"The next crawler that thinks he's not getting his fair share," he snarled, "will get a trip in space for his share!" He glanced down at the unconscious man and jerked his thumb toward the hatch. "Get him out of here!"

Two men dragged the unconscious man away and threw a bucket of cold water on him. He woke up, snatched at his share of the credits, and disappeared from the room.

The pirate captain continued reading the list of names, arbitrarily, handing out various amounts of the stolen money as he saw fit.

Standing in the rear of the messroom, hidden by the other members of the crew, Tom realized that to step in plain sight of Wallace and Simms for his share would mean instant betrayal. He had to make his move now, and with most of the crew mustered together in the messroom, it was his one chance for success.

Gripping the stolen paralo-ray gun in his jacket pocket, he slipped out of the messroom unnoticed and headed for the radar bridge.

As he raced up the companionway he could hear the laughter of the men below decks as one by one they received their shares. His name would be called soon. Heart pounding, he stopped outside the radar hatch, pulled the paralo-ray gun from his jacket, and taking a deep breath opened the hatch.

Joe Brooks was seated in front of the scanner counting his share greedily and glancing occasionally at the finger of light that swept across the green globe. When Tom opened the hatch, he looked up and smiled.

"Hiya, Kid," he said. "Coxine's all right. I got a thousand just for picking up that ship on the radar. How much did you collect?"

"This," said Tom. He shoved the paralo-ray gun into Brooks' stomach. The man gulped and finally found his voice.

"Say, what is this? A gag? Where did you get that paralo-ray?" Then suddenly he shoved the bundle of notes in his pocket. "Oh, no, you don't! You're not going to steal my share!"

"I don't want your money!" said Tom coldly. "Get into that locker and keep your mouth shut, or I'll blast you!"

"Locker? Say, what's the matter with you? You gone space happy?"

"Get in there," growled Tom. At the look on the cadet's face, Brooks rose quickly and stepped into the locker. Tom slammed the door and locked it. Then, locking the passageway hatch, he turned to the radar scanner. Working quickly with deft hands, he opened the casing around the delicate instrument and began disconnecting the major terminals. Studying the complicated tangle of connections, he wished that he had as much knowledge of radar as Roger.

He finally found the wires he wanted and separated them from the other connections. He began replacing them, altering the terminals. After checking his work, to make sure it would not short-circuit, he grabbed the intercom and began taking it apart. Sweat beaded his forehead. Time was short. Soon Coxine would miss him and come looking for him. He had to complete his job before that happened.

After moments that seemed like hours he was ready. Using one of the intercom relays he began tapping out a message in Morse code on an exposed wire from the scanner. He looked at the radar scanner and watched it flash white static lines each time he touched the wires. Carefully he tapped out a message.

" ... emergency ... attention ... Corbett ... Space Cadet ... aboard ... Coxine ... pirate ... ship ... space quadrant ... B ... section ... twenty ... three ..."

Over and over he repeated the desperate message, hoping against hope that someone would be scanning space and the interference would show up on their radar.

" ... emergency ... attention ... Corbett ... Space Cadet—"

"Captain Strong!" Roger's voice came shrieking over the ship's intercom. "Captain! Quick! I'm picking up a message from Tom!"

"What?" cried the Solar Guard officer. "Nail it! I'm coming up!"

Scrambling up the ladder to the radar bridge from the control deck, Captain Strong rushed over to the scanner and watched eagerly as blinking flashes washed out the background of the screen.

Slowly, at times unevenly, the message flashed and the two spacemen read it with gladdening hearts. Strong made a careful note of the position while Roger continued to read the flashes. Turning to the astrogation panel, the Solar Guard captain quickly plotted a course that would bring them to Tom's position.

Endlessly, during the past few days, Strong, Roger, and Astro had swept space in a wide arc around the asteroid belt, hoping to pick up just such a signal. Now, with the position of the Avenger in his hands, Strong grabbed for the intercom.

"Attention, power deck!" yelled Strong. "We've just picked up a message from Tom. He's given us his position, so stand by for a course change."

"Yeee-eooow!" roared Astro. "I knew he'd do it."

"He's not in the clear yet. We've only got his position. We don't know how we're going to get him away from Coxine yet."

"Ready to change course, sir," said Astro.

"Three degrees on the down-plane of the ecliptic, and fifty-four degrees to starboard. Full space speed, Astro! Pile it on!"

"Aye, aye, sir!" replied Astro. "I'll make this wagon's tail so hot it'll blast at double speed!"

"You'd better, you Venusian ape!" cried Roger. "It's the least you can do for Tom!"

"Stow it, Manning," growled Astro good-naturedly, "or I'll stick some of your hot air in the jets for extra power!"

"Cut the chatter, both of you!" snapped Strong. "Astro, execute course change!"

Astro's reply was a blast on the steering rockets. On the control deck, Strong watched the needle of the astral compass swing around and stop dead on the course he had ordered.

"All set, Astro!" shouted Strong. "Right on course. Now pile on the neutrons!"

"Aye, aye, sir."

On the power deck, the big cadet turned to his control panel, took a deep breath, and opened the reactant feeders wide. The ship leaped through the airless void under the sudden burst of power and Astro watched the acceleration indicator climb to the danger line. He gulped as the needle passed the danger point and was about to cut down speed when the needle stopped. Astro breathed easily and settled back satisfied. If it was up to him, they would reach Tom in record time.

Up on the radar deck, Roger continued to read the flashing signals on the radar scanner. Over and over, he read the same message.

"I guess that's all he can say, sir," said Roger, turning to Strong.

"Yes, I guess so, Roger," agreed Strong. "He's probably sending it out blind, on an open circuit, hoping that anyone near enough would pick it up. Wonder how he did it?"

Roger thought a moment. "I'm not sure, sir, but I think he's crossed the impulse on the scanner from positive to negative."

"How do you mean?" asked Strong. The young captain was well acquainted with the principle of radar but, admittedly, could not match Roger's natural ability.

"By making the impulse negative, sir," said Roger, "he could create interference on the scanner. Instead of bouncing against something and returning an image to a scanner, the impulse hits itself and creates static which shows up in the form of those white flashes."

"Well, in any case," said Strong with a sober nod toward the scanner, "he's done something the whole Solar Guard couldn't do. He's quite a boy!"

Roger smiled. "I'll say he is, skipper!"

Strong turned away and climbed down to the control deck. He sat in front of the great control panel and watched the countless dials and needles. But his mind wasn't on the delicate handling of the great ship. He was thinking about Tom, alone aboard a ship with a crew of desperate criminals.

Tom had taken his life in his hands to send out the message, that much Strong was sure of! And the young skipper noted with pride that there was no appeal for help in the desperate call.

He shook his head wearily and flipped the teleceiver switch to report to Commander Walters.

"Emergency ... attention...." Tom continued to tap out the message slowly and carefully. Behind him, he could hear Brooks hammering against the locker door. Tom felt like opening the door and freezing the pirate with his paralo-ray gun to keep him quiet, but he didn't dare to stop sending.

Finally Tom decided it was time to go. "If anyone's going to pick up the message," he thought, "they've picked it up by now. I may still have time to get away in a jet boat."

He tied the wires together, causing a continuous interference to be sent out, and secured the radar casing. "If I'm lucky enough to get away in a jet boat," thought Tom, "at least they won't be able to pick me up on that!"

Without a glance at the locker where Brooks continued to pound and yell, Tom turned to the hatch leading to the passageway. He gripped the paralo-ray gun and opened the hatch. Peering into the passageway and finding it deserted, he slipped out and closed the hatch behind him. From below, he could hear the roar of the crew as the last of them received his share of the stolen credits.

Tom raced down the companionway toward the jet-boat deck. He made the first deck safely and was about to climb down to the next when he was spotted by Attardi, the scar-faced spaceman, who stood at the bottom of the ladder.

"Hey, Kid!" Attardi shouted. "The skipper's been looking for ya. You got the biggest cut. Three thousand credits for that fancy shooting you did!"

Tom noticed the gleam of the knife at the man's side. The young cadet could imagine the criminal sinking the knife in his back without hesitation, if he suspected anything.

"Well," demanded Attardi, "are you going to collect or not? The skipper sent me to look for you."

Tom smiled, and while still smiling, whipped the paralo-ray gun into sight and fired. His aim was true. Attardi froze, every nerve in his body paralyzed. He could still breathe and his heart continued to beat, but otherwise, he was a living statue, unable to even blink his eyes.

Tom jumped past the spaceman and dashed for the jet-boat deck. He had to hurry now. Attardi would be discovered any moment and be neutralized. When neutralized, the victim returned to normal, with only violent muscle soreness remaining.

Tom reached the jet-boat deck, opened the hatch, and raced for the nearest small craft. Suddenly from behind he could hear the buzz of a paralo-ray on neutralizing charge. Attardi had been discovered.

Tom jumped into the nearest jet boat, closed the hatch, and pressed the button releasing the sliding side of the ship's hull. Slowly, the great wall of metal slid back exposing the cold black velvet of deep space. As soon as the opening was wide enough, Tom pressed the acceleration lever and the small ship shot out, its jets roaring.
