TRS CLEOPATRA FLEET BASE CANALOPOLIS MARS STOP SUBJECT ORDERS STOP ROUTE LUNA PHOBOS SYRTIS MAJOR TRANSSENDERS PRIORITY AAA STOP MESSAGE FOLLOWS STOP TRS CLEOPATRA AND ALL ATTACHED AND OR ASSIGNED PERSONNEL A tense week passed and then the ship neared the spot where a change over to prime-space could be effected. According to Bayne's calculations, 40 Eridani C would be within 40,000,000 miles of them when the ship emerged from hyper space. ASSIGNED TEMP DUTY BUREAU RESEARCH AND DEVELOPMENT STOP SUBJECT VESSEL Cleopatra Cleopatra's close at hand to probe. Anthropoid inquisitiveness prevailed. Ship Cleopatra in the Combined Solarian Navies, bless her little iron "Tethys isn't so bad," protested Strike. they had worked together to pull Admiral Gorman's flagship Atropos they were strongly suspected of having interstellar flight.... So, reflected Strike, the transfer of the Cleopatra to Tethys for Cleopatra's Cleopatra's crew was a unit ... a team in the true sense of the word. They served in her because they wanted to ... would serve the crew. If any of them are in the brig, let me know. I'll be on the bridge." "What time do you want to lift ship?" "0900 hours." club and heaved a heavy sigh. "Tethys, here comes Lover-Girl. It's Cleopatra . Only one tube-liner burned through, and only six hours wasted in nauseous free-fall. Tethys. But her satisfied repose was interrupted almost before it was begun. Swarms of techmen seemed to burst from the dome and take her over. Welders and physicists, naval architects and shipfitters, all armed with voluminous blueprints and atomic torches set to work on her even before her tubes had cooled. Power lines were crossed and re-crossed, shunted and spliced. Weird screen-like appendages were Cleopatra's Cleopatra chosen?" added Celia curiously. "Well, I'll make it short," Ivy said. "We're going to make a hyper-ship out of her." "Hyper-ship?" Cob was perplexed. Ivy Hendricks nodded. "We've stumbled on a laboratory effect that warps space. We plan to reproduce it in portable form on the Cleopatra ... king size. She'll be able to take us through the hyper-spatial barrier." "Golly!" Celia Graham was wide-eyed. "I always thought of hyperspace as through. I sent a UV teletype to Admiral Gorman at Luna Base ... and here you are." "Why us?" Cob asked thoughtfully. "I'll answer that," offered Strike, "Lover-Girl's a surge circuit monitor, and it's a safe bet this operation takes plenty of power." He looked over to Ivy. "Am I right?" the group-mind.... He heard himself saying sharply into Ivy's communicator: "See to it that my ship is fueled and armed for space within three hours!" "Hold on, Strike!" Ivy Hendricks intervened, "What about the tests?" "I'm temporarily under Research and Development command, Ivy, but Regulations say that fighting ships cannot be held inactive during wartime! The Cleopatra's a warship and there's a war on now. If you can have your gear jerry-rigged in three hours, you can come along and test it when we have the chance. Otherwise the hell with it!" Strykalski's face was dead set. "I mean it, Ivy." "All right, Strike. I'll be ready," Ivy Hendricks said coolly. Exactly three hours and five minutes later, the newly created hyper-ship that was still Old Aphrodisiac lifted from the ramp outside the Substation dome. She rose slowly at first, the radioactive flame expect orders from Luna Base ordering them either to attack or Cleopatra or her crew. Ivy Hendricks joined them after stowing her gear, and when Whitley asked her opinion, she agreed with Strike. Her experiences with Gorman "Yes, sir." "And that," shrugged Ivy Hendricks, "Is that." Three weeks passed in the timeless limbo of second-order flight. Blast Cleopatra rode the curvature of space toward Eridanus. At eight and a half light years from Sol, the second-order "Communications here." "Notify Luna Base we have made contact. Give their numbers, course, and speed!" Ivy could feel her heart pounding under her blouse. Her face was ready to fight his ship if need be ... and against lop-sided odds. But years of training were guiding him now. them." "Yes, Captain." Strike turned to Ivy Hendricks. "Let's get back to the bridge, Ivy. It's going to be a hell of a rough half hour!" As they turned to go, all the pin-points of light that were the stars speed. Within seconds, contact would be made with the advance units of the alien fleet. Old Aphrodisiac readied herself for war. the thing that was the group-mind of the Eridans guided the thousand leathery tentacles that controlled the hundred and fifty black spaceships. The soft quivering bulk of it throbbed with excitement as The alien weapons were too strange, too different from anything her builders could have imagined or prepared her to face. The net sucked the life from her second-order generators, and she slowed, like the her flanks as she turned and twisted. One touched her atmospheric fins and melted them into slowly congealing globes of steel glowing with a white heat. She fought back with whorls of atomic fire that sped from her rifles to wreak havoc among her attackers. Being non-entities in themselves, and only limbs of the single mentality that rested secure on its home world, the Eridans lacked the vicious will to live that drove the Tellurian warship and her crew. But their numbers wore her down, cutting her strength with each blow that chanced to connect. space and leathery aliens died, their black ships burst asunder by the violence of new atoms being created from old. But there were too many. They hemmed her in, heat rays ever slashing, wounding her. Strykalski fought her controls, cursing her, coaxing commission for at least six hours. And they couldn't last six hours. They couldn't last another ten minutes. It was only the practiced hands of her Captain and crew that kept the Cleopatra alive.... "We're caught, Ivy!" Strike shouted to the girl over the noises of battle. "She can't stand much more of this!" Ivy stumbled across the throbbing deck to stand at Strykalski's side. "The hyper drive!" she yelled, "The hyper drive!" It was a chance. It was the only called over his shoulder, "Check with Engineering! See if the thing's hooked into the surge circuit!" She struggled out of the flying bridge and down the ramp toward the engine deck. Strike and Cob stayed and sweated and cursed and fought. It seemed that she would never report. At last the communicator began to flash red. Strike opened the circuit with his free hand. "All right?" he demanded with his heart in his Cleopatra came into the bridge softly ... just to be near her friends. It was only the fact that they could return at will to their own space ... and the danger of the questing Eridans ... that kept one or reassurance he did not feel. Then Strike broke the spell. The effort was great, but it brushed away the shadows that had risen to plague them from the tortured abyss of Cleopatra demanded attention and service, and her demanding saved Cleopatra
