and flame. We were so close our helmets almost touched. But she wasn't looking at me. Six feet from my swaying knees she was making frantic gestures with her magneto-wrench, her face a twisting mask of horror. Her body was twisting too and she seemed to be fighting off something I couldn't see! Frantic with alarm, I strained forward and threw my right arm about her. At least, I thought I did! But my iron-weighted wrist seemed to pass right through her! It whipped through emptiness to strike the hull with an impact that sent a stab of pain darting up my arm to my shoulder. The pain was agonizing for an instant; then it fell away. At the same instant I saw the light. It was faint at first, a pale spectral glow that haloed her helmet and lapped in concentric waves about her knees. It wasn't a flame whorl. It gave off iridescent glints and grew swiftly brighter, turning from pale blue to dazzling azure. Then it became a weaving funnel of light that spurted from the hull with a low humming sound. The humming was unearthly. It penetrated my helmet and became a shrill inward keening with a quality hard to define. Imagine a butterfly of sound struggling fiercely to escape from a sonic chrysalis. It was a little like that, a kind of shrill fluttering on the tonal plane. The light did not remain attached to the hull. It shot up into the void and became a vertical shaft of downsweeping radiance. From its summit pulsing ripples ascended, giving it the aspect of a waterfall. Then it became a prism, flashing with all the colors of the spectrum. A man may awaken from a nightmare, stare for an instant into the darkness and try to rationalize his fears. But this was no nightmare! As I stared up the iridescence was replaced by a leaf-screen effect shot through with crimson filaments. Shadows appeared amidst the ripples, straight and jagged lines of some tenuous substance that seemed to mold itself into a pattern. It may have been imagination. But for the barest instant as I stared at the incredible shape of radiance a face seemed to look out at me. A fat face, bloated, toadlike, supported by a shadowy neck that swelled out beneath it like the hood of a rearing cobra! Suddenly my scalp crawled and my helmet seemed to contract, pressing against my skull with a deadly firmness. An electrolube!
