The passage was dimly blue-lit. We descended its length, came to the main corridor, which ran the length of the hull. A vaulted metal passage, with doors to the control rooms opening from it. Dim lights showed at intervals. * * * * * The humming of the ship was more apparent here. It drowned the slight humming of my cloak. I crept after Anita; my hand under the cloak clutched the ray weapon. A steward passed us. I shrank aside to avoid him. Anita spoke to him. "Where is Miko, Ellis?" "In the ventilator-room, Mr. Prince. There was difficulty with the air renewal." Anita nodded, and moved on. I could have felled that steward as he passed me. Oh, if I only had, how different things might have been! But it seemed needless. I let him go, and he turned into a nearby door which led to the galley. Anita moved forward. If we could come upon Miko alone. Abruptly she turned, and whispered, "Gregg, if other men are with him, I'll draw him away. You watch your chance." What little things may overthrow one's careful plans! Anita had not realized how close to her I was following. And her turning so unexpectedly caused me to collide with her sharply. "Oh!" She exclaimed it involuntarily. Her outflung hand had unwittingly gripped my wrist, caught the electrode there. The touch burned her, and close-circuited my robe. There was a hiss. My current burned out the tiny fuses. My invisibility was gone! I stood, a tall black-hooded figure, revealed to the gaze of anyone who might be near! The futile plans of humans! We had planned so carefully! Our calculations, our hopes of what we could do, came clattering now in a sudden wreckage around us. "Anita, run!" If I were seen with her, then her own disguise would probably be discovered. That above everything would be disaster! "Anita, get away from me! I must try it alone!" * * * * * I could hide somewhere, repair the cloak perhaps. Or, since now I was armed, why could I not boldly start an assault? "Gregg, we must get you back to your cubby!" She was clinging to me in a panic. "No! You run! Get away from me! Don't you understand? George Prince has no business here with me! They'd kill you!" Or worse--- Miko would discover it was Anita, not George Prince. "Gregg, let's get back to the deck." I pushed at her. Both of us in sudden confusion. From behind me there came a shout. That accursed steward! He had returned, to investigate perhaps what George Prince was doing in this corridor. He heard our voices; his shout in the silence of the ship sounded horribly loud. The white-clothed shape of him was in the nearby doorway. He stood stricken in surprise at seeing me. And then turned to run. I fired my paralyzing cylinder through my cloak. Got him! He fell. I shoved Anita violently. "Run! Tell Miko to come--tell him you heard a shout! He won't suspect you!" "But Gregg--"
