hand clawed at his belt for a weapon. Only power-rapiers had been allowed them individually until a landing was effected, and it was fortunate, for as the clawing fingers closed about the rapier's hilt, an unholy light came into the Neptunian's eyes. Bill heard a thunderous battle-cry as a bulky shape sprang between him and the Neptunian, but he swept his rescuer aside. It was the Amazon, her own power-rapier drawn for battle. "No interference!" he exclaimed in a voice as cold as outer space. His own blade was in his hand now, the flexible Columbium-steel activated by the dreadful electronic fire. The touch of that blade disintegrated flesh and bone and metal even. They were face to face now, confronting each other with the wary savagery of Venusian Ocelandians. The smell of death was in the air, and too, the wordless, tremendous, inarticulate vibration from an unknown source that seemed to hint at inconceivable horror, and ebbed and flowed about them. They could all sense it now, as it increased as if in a crescendo of triumph. And at that instant the Neptunian struck. One moment they were circling for an opening, their ghastly weapons ready, and the next the singing blades met in midair as Bill Nardon parried the slashing blow. And then reason tottered as time stood still. Where the blades had been a flaring vortex of unendurable blue light sprang between them like a hellish fan of electronic fury opening before their eyes. The Neptunian's blade had disappeared, consumed in the incredible holocaust; only the neutralized hilt of Vulcanite remained in his palsied hand as they reeled aside, blinded and unnerved. Bill's blade swished through the air as he reversed it and struck the Neptunian on the left temple with the Vulcanite hilt. The man's knees went rubbery and without a sound he slumped to the floor. "The screen ... throw on the Multi-Energon screen!" Bill bellowed. "This man was being directed, someone else may be next!" The powerful hum of the inner screen within the cruiser, that rendered everything within impervious to every known power, arose in the brief silence. And none too soon. Suddenly the cruiser lurched, and trembled like a great wounded stallion. Bill had a confused picture of the addled members of several planets clinging to ultra-mullioned gravity seats as the ship began to spin. Every possible aid of science had been lavished on the cruiser, even to the most exacting provisions against physical injury, or the danger from an unexpected crash-landing
