prisoners scrambled for safety, but with no real intention of releasing the deadly electric charge along the paths provided for it. This cruel pleasure cost him his life. As he turned his back Quirl leaped. His iron-hard forearm rose and fell, and the edge of his hand came down on the back of the pirate's thick neck. There was a muffled crack and he slumped to the platform grating.
Quickly the officer stripped off the man's harness and buckled it around his own naked chest. The electrogun had been uninjured, and hooked to the belt was also the riot club, a truly appalling thing at close quarters. Quirl carried the body down, laid it prone in the corner he had occupied, snapped on the waistlock, and threw a ragged old blanket over the hairy legs. In the forthcoming disturbance, if anyone looked in, he would think the inert form a sleeping prisoner, and that the guard had deserted post.
Quirl had feared an outbreak among the prisoners, but they were so apathetic that they paid little attention. Perhaps they thought it was Quirl who had been killed, and he did not dare even a whispered farewell to the girl he knew was watching somewhere in the darkness.
Much to Quirl's delight, the long, tubular passage was deserted. Here the centrifugal gravity was less than it had been in the hold. A weird place, this central tube, where every direction was down, and a man could walk on his ceiling, his floor, his walls with equal facility. No top nor bottom — just a long, smooth tube with numerous enigmatic doors leading to — where?
At least it was easy to tell where the bow of the ship was. A light shone through a transom over the door to the navigating room. Should he try to hold up the navigating officer? He decided against that. There would be at least three men in there, and it was the custom to keep those quarters locked.
'If only I knew where they generate the invisibility field!' he muttered, as he stood irresolute.
Opportunity came at that moment. A crack of light appeared along the passage. A door was opening there. A moment later a head and shoulders showed. Someone was climbing up. Swiftly the officer ran to the place. The pirate did not even suspect anything wrong until he felt the spots of milky light on his face. He showed his terror plainly.
'Get up!' Quirl hissed. The man obeyed with alacrity. Quirl glanced down. He saw tiers of bunks, evidently one of the crew's dormitories.
He now turned to the cowering pirate.
'I'd as soon kill you as not!' Quirl snarled.
'You got me wrong, brother!' the pirate whined. 'I'm with Gore in this deal. Lay off!'
'Where you bound for?'
'I have to relieve Burke at the ventilating turbines.'
'Let Burke wait. Lead on to the invisibility generators.'
'Oh, I can't do that, mister! I got to have a pass. Say, mister, I was just kidding about being one of Gore's men. I'm for the cap'n, yes, sir!'
'You lying scum!' Quirl barked impatiently. 'Get going!'
The white-faced and bewildered pirate led the way down the tube to the after end. He unlatched a door and tried to enter, but as soon as he had dropped through to the platform he was met by a guard with leveled ionizer.
'This gem'man,' he started to explain. But Quirl dropped after him and gave him a powerful shove, so that he crashed into the guard. The latter pulled the trigger, and the unfortunate pirate crashed over the platform's edge to the floor. Quirl had out his own electrogun and dispatched the guard. At the same time he felt a stunning shock. His senses reeled, but the grating had taken part of the discharge loosed by a pirate electrician at the foot of the ladder. Quirl threw his riot club and followed that up with another lightning bolt.
He was then the only living person in the room, in which two generators hummed softly. Connected to them was a bank of U-shaped tubes, each as tall as a man, which were filled with silent livid fire. Quirl picked up a wrench and started hammering at the thick tubes until the glass cracked. Each time he was engulfed by a wave of heat, and the tube became black. The great generators idled and automatically came to a stop. Quirl was certain now that the pirate ship would be visible, but the position of the captives was still desperate. He hoped that none of the surviving pirates would think of calling at the generator room, or find out in some other way that they were now visible in the eternal day of space.
Quietly he climbed back to the passage and closed the hatch. He cast about for his next move. He was looking toward the bow, but on hearing the subdued clink of metal on metal, he turned.
A dozen of the pirates were coming toward him.
It would have been useless to draw his weapon. Theirs were out and could have burned him to a crisp before he could move. Silently and with deadliness apparent in every move they approached him.
'Hope they try to capture me alive!' he thought. 'What a dog-fight that'll be!'
Now they were nearly up to him.
'Come along, you fool!' barked the leader of the group as they were all around him. 'Sapheads like you'll give the whole game away.'
Quirl could have laughed. This was evidently part of the mutineers' crew bent on their errand of murder. In the dim light they had taken him for one of their number. He went with them, meekly.
'Unlocked!' The leader whom Quirl had not seen before, exclaimed with satisfaction. He pulled the hatch open softly and the hinges had been oiled. Quietly as panthers they descended the ladder. They stood at the bottom. Still another door barred the way. Quirl now realized that they were attacking the captain's quarters. But the leader produced a key, and silently swung the door open.
'So, you dogs! You've come!'
Like an infuriated bull Captain Strom charged them, a riot club in each hand. He could have killed them all with a ray, but he chose to vent in physical action his consuming anger at their treachery, which he had in some way anticipated. Three or four went sprawling under his mighty blows. The others sought shelter behind tables and chests, and began stabbing at him with their electroguns. Electricity crackled, and the air became pungent with ozone. A pair of the twin rays struck the captain's gold braid, and he went down. With a triumphant yell a man dashed at him, murderous club up-raised. But Quirl was faster, and the pirate fell dead with a crushed skull.
Strom was up again, fighting beside Quirl. The pirates remaining fell under their furious blows, and the two dashed out. Strom said nothing, and Quirl was not sure that he had been recognized. The captain charged straight for the navigating bow. Here, unless he should be attacked by the I.F.P. he could still control the situation. He was perhaps still ignorant of the ship's visibility.
But Quirl made for the prisoners' hold. They would be cowering there, probably in darkness, not knowing what was going on. It was his intention to rally them, provide them with the weapons of the fallen pirates, and so be in a position to advantageously make terms with whoever was victorious in this battle.
He saw, as he approached that the light was on. He was hardly a dozen feet away when the door was darkened. Quirl did not have to hear her cry to know that Gore had Lenore.
Running with remarkable speed, the mate carried his prize toward the after end of the tube. A hatch stood open there, and he dropped through, slamming it after him.
Quirl picked up a bar that someone had dropped. It was but a matter of moments to break the lock and pull open the hatch. The hold was lighted, and empty. In its middle, holding the helpless Lenore, stood Gore, the electrogun in his hand covering the platform.
'Boy scout to the rescue again!' Gore sneered. He was even more repulsive than before, with the marks Quirl had left on him in the last battle. But he was fearless and utterly reckless. 'Well, m'lad, I know when I'm done. And when a fellow's done he don't care what happens. So here's the lay: When I get out of here, I'll be dead. And
Quirl tentatively placed one foot on the platform. Instantly a fat spark jumped from the metal to his foot, and
