<passage>:
marooned on a rogue planet—fighting to save himself from a menace weapons could not kill. [Transcriber's Note: This etext was produced from Planet Stories Fall 1944. Extensive research did not uncover any evidence that I'm afraid I can offer no competition to the beauties of five planets—or is it six? With regret I bow myself out, and knowing me as you do, you'll understand the futility of trying to convince me again. Anyway, there will be no temptation, for I'm sailing on a new assignment I've the palms of Venus, and of the blue ecstasy of her eyes, wide with a perpetual wonder—limpid as a child's. The barbaric rhythms of the 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 solitude—the fatal one of her swamps and virgin forests. 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. fault sheaf of credits—it had cost him the severe rebuff of the I.S.P., and most of his heart in Marla. Verbena , fragrant as a mint garden, in the tall frosty glass of Martian Bacca-glas semi-precious stones that studded her brief gauze skirt. And now, in a final bid for the spacer's favor she flung herself in his lap and tilted back invitingly. handsome, red-haired spacer, but from the table across, came the tinkling sound of a fragile glass being crushed in a powerful hand, and a muffled Martian curse. Without warning, the Martian was on his feet with the speed of an Hellacorium, the table went crashing to one side as he leaped with deadly intent on the sprawled figure of Dennis Brooke. A high-pitched scream brought instant silence as a Terran girl cried out. Then the Martian's hand reached out hungrily. But Dennis was not there. the murderous rush of the Martian youth, then he wheeled swiftly and planted a sledge-hammer blow in that most vulnerable spot of all Martians, the spot just below their narrow, wasp-like waist, and as the Martian half-doubled over, he lefted him with a short jab to the chin that staggered and all but dropped him. The Martian's violet eyes were black with fury now. He staggered back it, flat-footed, without flinching then he let his right ride over with all the force at his command. It caught the Martian on the jaw and interplanetary League. Only major criminals and space pirates still without the law were known to possess them. "Looks like your brawl has turned out to be a piece of fool's luck, in his possession a disintegrator? Pity we have no complete records on that devil's crew! Anyway, we'll radio the I.S.P., perhaps they have details on this dandy!" He eyed admiringly the priceless Martian embroideries on the unconscious Martian's tunic, the costly border of red, ocelandian fur, and the magnificent black acerine on his finger. "Better come to Headquarters with me, Dennis," the lieutenant said 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 to say were difficult indeed. "Marla Starland, your fiancee, accepted an assignment we offered her—a 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 precision. "Marla!" He breathed at last. The thought of Marla in the power to show a crowded space port on Venus, and a gigantic passenger spacer up-tilted in its cradle. space and then fell into orbit there beyond the planetary attraction of Venus. On the three-dimensional viso-screen it was uncannily real. 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." "When do I leave, Commander!" Dennis Brooke's voice was like a javelin of ice. "Right now, if you wish. We have a new cruiser armored in beryloid with double hull—a new design against Genton shells, but it's the speed 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 the luxurious offices and appointments of the regular I.S.P. Patrol commanded through the teleradio from the control room: "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 survey. "No doubt about it," he spoke through the radio in his helmet. "Cargo thinking of her and all he had lost. When he finally spoke, his voice was harsh, laconic: "Prepare to return!" major battle, or hell and high water and back again, for that matter, 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 but a pirate crew with swift battle cruisers could dare! This was the dangerous asteroid belt, where even planetoids drifted in eccentric uncharted orbits. 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 meet them. The readings in the Planetograph seemed to have gone crazy. It showed diameter 1200 miles composition mineral and radio-active. Gravity seven-eighths of Terra. It couldn't be! Unless perhaps this 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 them in a free fall, then the Planetoid was rushing up to engulf them. III the sky, and the iridescent soil of the narrow valley that walled in the cruiser, had a poisonous, deadly look. As far as their eyes could 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 job...." That wasn't at all what he'd intended to say. But somehow the words had stuck in his throat and his face flushed deep scarlet. His on my ship. Get it!" The last two words cut like a scimitar. Dallas nodded and lowered his eyes. Scotty shifted his cud and spat a thin stream of juice over the iridescent ground. One by one they
