For those seconds Rollins took it with no answering shot. Would his forepeak dome hold? I could see the tiny puff of fountain-light there where the violet beam was boring. And then Rollins answered! From his stern-peak this time diagonally away from us, his beam shot out. Not directly at us, but at our bolt-stream. Two great violet rapiers in space, sliding one upon the other. Midway between the vessels they clashed. The interference cut our beam from Rollins' vessel. Out there in space for breathless seconds both the beams held firm. Amazing sight of pyrotechnic beauty, that area where the beams clashed. Another ten seconds, each of them an eternity. The giant circle of the interference area slowly was backing toward Rollins' ship! Our beam, at reckless full-power now, was pushing it back. Only twenty or thirty miles now from its target. A buzzer sounded at Jerome's elbow. He reached for his audiphone. The panic-stricken voice of our controlman in the ship's hull sounded: "Chief! Dynamo bearing running hot! An' we're almost at zero in the main battery." Jerome disconnected with a grim curse. Another few seconds. The narrowing angle of the hurtling ships had brought them within a hundred miles of each other. And then suddenly, again it was Rollins who was the more cautious. From the tail of his vessel a stream of burning gas suddenly was issuing. A widening fluorescent comet-tail streaming out behind him. And then he was turning, heading away from us! In retreat! The interference area of the two clashing sword-beams broke. The great prismatic spark shower died. Our bolt, plunging through, for a second may have struck the turning, retreating Rollins. No one here could say. Rollins' bolt had snapped off. The image of his ship merged with the gas cloud. Vanished behind its masking cloak. Jerome snapped off our beam. His face was triumphant; his enemy fleeing, trying to mask his retreat with a cloud of burning gas. "By Heaven, I've got him!" Jerome was muttering. "Damn' fool, trying to fight the Phantom." The starfield swung as we turned, headed at the gas-cloud where it hung in a vast luminous fog of prismatic color as though a comet had burst there. Triumphant pursuit of our enemy. But I held my breath. I found Brenda beside me. Her hand, cold dank, gripped mine. Our eyes met. There was nothing to say. Surely we both knew what little chance we had of coming out of this alive. The luminous gas-cloud swarmed to the sides as our ship plunged headlong into it. And then we were through it. * * * * * There was no warning as Rollins' bolt struck us! He had not tried to escape but was poised here in ambush, bow toward us, no more than fifty miles away, off to one side by skilled calculation so that there was only his narrow bow as our target and we were almost broadside to him!
