According to Bayne's calculations, 40 Eridani C would be within 40,000,000 miles of them when the ship emerged from hyper space. And then the Radar section picked up the planetoids. Millions of them, skin. in all directions for more than half a parsec ... dull, rocky little worlds without a gram of detectable mass. All that waited for the Cleopatra's Cleopatra with the rapacious Eridans. With typically human adaptiveness they had sublimated their fear of the unknown space in which they found Ship Cleopatra in the Combined Solarian Navies, bless her little iron rump! Gorman means us.

So, reflected Strike, the transfer of the Cleopatra Cleopatra's Cleopatra's bridge." "What time do you want to lift ship?" "0900 hours." How long, he couldn't have known ... then. The flight out was uneventful. Uneventful, that is for the T.R.S. Cleopatra . Only one tube-liner burned through, and only six hours wasted in nauseous free-fall. Lover-Girl wormed her way through the asteroid belt, passed within a million miles of Jupiter and settled comfortably down on the airless field next to the glass-steel dome of the Experimental Substation on 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 welded to her bow and stern. Workmen and engineers stomped through her Cleopatra's been disposed of, "is what's with this 'Project Warp'? What are you Cleopatra chosen?" added Celia curiously. "Well, I'll make it short," Ivy said. "We're going to make a hyper-ship out of her." warps space.

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 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 of stars below Orion that formed the constellation of Eridanus. When Cob asked why, Strike replied that knowing Gorman, they could reconnoiter the 40 Eridani C system of five planets. Strykalski added Cleopatra or her crew. Ivy Hendricks joined them after stowing her gear, and when Whitley Cleopatra rode the curvature of space toward Eridanus. At eight and a half light years from Sol, the second-order was cut so that Bayne could get a star sight. As the lights of the and astern, brilliant Sirius and its dwarf companion showed definite disks in the starboard ports. At a distance of 90,000,000 miles from the Dog Star, its fourteen heavy-gravity planets were plainly visible through the electron telescope. there?" The sound of the calculator came through the grill. Then Celia replied: "Range 170,000 miles, and there are more than fifty and less than two hundred. That's the best I can do from this far away. They seem to have some sort of radiation net out and they are moving into spread formation." Strike cursed. "They've spotted us and they want to scoop us in with ship. They were in second-order flight again, and traveling above light speed. Within seconds, contact would be made with the advance units of the alien fleet. Old Aphrodisiac readied herself for war. atmosphere grew tense as the Tellurian warship drove full at the pulsating net of interlocked force lines. Parsecs away, on a frozen spaceships. The soft quivering bulk of it throbbed with excitement as it prepared to kill the tiny Tellurian thing that dared to threaten its right to conquest. Old Lover-Girl tried gallantly to pierce the strange trap. She failed. 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 their numbers wore her down, cutting her strength with each blow that chanced to connect. Torpedoes from the tubes that circled her beam found marks out in 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, The second-order drive was damaged, not beyond repair, but out of 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 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. Cleopatra !" Cob and Strykalski rushed back to the port, straining to see the back-curving plates of the hull. Ivy was right. The metal, and to a 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 gyro-headings." "What?" The astrogator sounded as though he thought Strike had lost his mind. "Through The second-order drive repaired, Old Aphrodisiac moved out through the alien space toward the spot where 40 Eridani C existed on the other side of the barrier. The ship's tactical astrophysicist brought in some disturbing reports accepted classifications in all particulars ... except one. And that one had the scientist tearing his hair. The mass of every observable body except the ship herself was practically non-existent. Even the two planetary systems discovered by the electron telescope flouted their impossible lack of mass. Ivy suggested that since the Cleopatra and her crew were no part of this alien cosmos, no prime-space instruments could detect the errant
