to redeem himself by capturing Koerber whose ships were the scourge of the Void. But his luck had run its course, and now he was marooned on a rogue planet—fighting to save himself from a menace weapons could not kill. there will be no temptation, for I'm sailing on a new assignment I've in silence and salvage something out of the wreck of his heart, not to speak of his career. But Venus, in the throes of a gigantic boom upon the discovery of radio-active fields, could offer only one When the minor adventures of the heart begin to pall. If the loss of Marla left an aching void that all the women of five planets could not fill, the loss of Space, was quite as deadly. For he had been grounded. True, Koerber's escape from the I.S.P. net had not quite been his but had he not been enjoying the joys of a voluptuous Jovian Chamber, in Venus' fabulous Inter-planetary Palace, he would have been ready for duty to complete the last link in the net of I.S.P. cruisers that almost surrounded the space pirate. interplanetary League. Only major criminals and space pirates still without the law were known to possess them. gently. "We'll say you captured him, and if he's Koerber's, the credit's yours. A trip to Terra's what you need, Venus for you is a hoodoo!" The stern, white haired I.S.P. Commander behind the immense Aluminil two reasons. The first one you already know—your capture of one of Koerber's henchmen—has given us a line as to his present orbit of piracy, and the means of a check on his activities. But that's not really why I've brought you here." He frowned again as if what he had delicate piece of work here on Terra that only a very beautiful, and very clever young lady could perform. And," he paused, grimacing, "somewhere between Venus and Terra, the interplanetary spacer bringing her and several other passengers, began to send distress signals. Finally, we couldn't contact the ship any more. It is three days overdue. All passengers, a cargo of radium from Venus worth untold in space. This, Dennis," the Commander emphasized his words, "is your chance to redeem yourself!" He fell silent, while the viso-screen began to show a crowded space port on Venus, and a gigantic passenger spacer A flight that had taken many hours to accomplish, was shortened on Terra in emergency spacers, or are picked up in space by other transports ... and sometimes son ... well, as you know, sometimes they're never seen again." it's serviced and fueled and the crew's aboard." He extended his hand. "You're the best spacer we have—aside from your recklessness—and on your success depends far more than the capture of Their nerves were ragged. Days and days of fruitless search for a phantom ship that seemed to have vanished from space, and an equally elusive pirate whose whereabouts were hidden in the depths of fathomless space. To all but Captain Brooke, this was a new adventure, their first assignment to duty in a search that went beyond the realm of the inner planets, where men spent sleepless nights in eternal vigilance against stray asteroids and outlaw crews of ruthless vandal ships. Even their cruiser was a new experience, the long, tapering fighter lacked "Prepare to board!" Every member of the crew wanted to be among the boarding party, for all but George Randall, the junior member of the crew had served his apprenticeship among the inner planets, Mars, Venus and Terra. He felt nauseated at the very thought of going out there in that vast abyss of space. His young, beardless face, with the candid blue eyes went pale George Randall breathed a sigh of relief. He watched them bridge the space to the drifting wreck, then saw them enter what had once been a proud interplanetary liner, now soon to be but drifting dust, and he turned away with a look of shame. Inside the liner, Captain Dennis Brooke had finished making a detailed survey. Somehow he had expected to find at least one compartment unharmed, shifted the Venusian weed that made a perpetual bulge on his cheek and gazed curiously at Captain Brooke. They all knew the story in various versions, and with special additions. But they were spacemen, implicit in their loyalty, and with Dennis Brooke they could and did feel safe. Tom Jeffery, the tall, angular and red-faced Navigator, whose slow, easygoing movements belied the feral persistence of a tiger, and the swiftness of a striking cobra in a fight, led the small procession of men toward the emergency planes. Behind him came Dallas Bernan, third lieutenant, looming like a young asteroid in his space suit, followed by Scotty, and finally Captain Brooke himself. All left in silence, as if the tragedy that had occurred aboard the wrecked liner, had touched them intimately. Aboard the I.S.P. Cruiser, a surprise awaited them. It was young George Randall, whose excited face met them as soon as they had entered the airlocks and removed the space suits. "Captain Brooke ... Captain, recordings are showing on the new 'Jet Analyzers' must be the trail of some spacer. Can't be far!" He was new invention that detected the disturbance of atomic jets at great distance were his own achievement. Dennis Brooke smiled. His own heart was hammering, and inwardly he prayed that it were Koerber. It had to be! No interplanetary passenger but a pirate crew with swift battle cruisers could dare! This was the dangerous asteroid belt, where even planetoids drifted in eccentric uncharted orbits. Dennis, Tom Jeffery and Scotty Byrnes raced to the control room, followed by the ponderous Dallas to whom hurry in any form was member of the crew raced to his assigned task without delay. Action unmistakably for what it was—a pirate craft, it showed by its sudden maneuver that it had detected the I.S.P. cruiser. For it had described a parabola in space and headed for the dangerous asteroid belt. As if navigated by a masterly hand that knew each and every orbit of the asteroids, it plunged directly into the asteroid drift, hoping to lose forced to follow the pirate ship's plunge like the weight at the end of unknown planetoid was the legendary core of the world that at one time was supposed to have existed between Jupiter and Mars. Only that could possibly explain the incredible gravity. And then began another type of battle. Hearing the Captain's orders to Randall, and noting that no result had been obtained, Scotty Byrnes a man didn't exert himself. To the silent crew of the I.S.P. Cruiser, failed to be at his battle-station in time of emergency, had no place in the I.S.P. "Considering the gravity of this planetoid," Dennis Brooke said thoughtfully, "it's going to take some blast to get us off!" "Maybe we can locate a deposit of anerioum or uranium or something for our atom-busters to chew on!" Scotty said hopefully. He was an eternal to find out what happened to Koerber's ship. I must know," he said in a "Captain ... I ... I wanted ..." he paused unable to continue. with its crimson stains made an appealing, boyish figure. It softened the anger in Brooke's heart. Thinking it over calmly, Dennis realized this was the youngster's first trip into the outer orbits, and better men than he had cracked in those vast reaches of space. But there had been an instant when he'd found Randall cowering in the rocket-room, in him, he whirled and re-entered the ship.
