I sprang at him. He stepped aside and swung the pipe, catching me a glancing blow on the shoulder and knocking me across the ship and against the water purifier. The machine was already a shambles, both of us having hit it. The steam spurted into the room--water dripped on the floor. Bruised and cautious, I shuffled around the ship toward him. He stood waving the pipe like a batter in a baseball game, determined not to miss again. I could see it in his eyes. I moved within reach and he struck. But this time I didn't dodge. I caught the blow on my arm. Pain shot through it, but I'd caught the blow soon enough to prevent the full force from breaking the bone. As it hit, I seized the pipe with my other hand and twisted it sharply. It came out of Morrie's grasp. He lunged toward me. I threw him back with a punch aimed at his chin, landing on his chest instead. He crouched to attack and I threw the pipe at him. Once more I didn't figure on the ten per cent gravity. The pipe went over his head and crashed into the bulkhead at the other end of the ship. He sprang and I caught him. We stood with our magnetized shoes anchored to the floor, swinging, ducking, punching, each now angry enough to kill. We were about evenly matched as far as muscles and weight were concerned, but Morrie was showing the strength of a maniac. My punch staggered him but did no real damage. He came back and feinted. I suckered and he brought two punches against my chin and belly that sent me to the floor. Only the fact that I rolled with the punches kept me from being kayoed. He tried to dive on me, but I scrambled out of the way. We were both beginning to show some signs of damage. I had a soreness in the belly where he'd landed his blow, and his cheek had been cut by my knuckles. He dived at me again. I scored on his chin but he managed to get me in a clinch. We wrestled, partly on the floor, partly floating near the garden trays and the cable housing in the center of the compartment. Suddenly he grasped my shoulders and brought up his knee. It caught me in the groin and I screamed with pain. Somehow I caught one of the trays and hurled myself out of reach, but as I hit the floor I could hardly move. All the fight left me with that blow. Somewhere, I heard Gail calling: "Bill! Get up!" It was no use. I couldn't move my arms or legs. Morrie hesitated a moment. Then, deciding that I was helpless, he pushed himself to the bulkhead where the length of pipe lay. He meant to use it in an attempt to beat me to death. He reached the weapon, picked it up and held it a moment in his hand as he turned a savage look toward me. He came toward me, certain that I was no longer able to defend myself. I rolled away, the pain nearly killing me. Then I wrapped my legs around his and tripped him, in spite of the pain in my groin. He dropped the pipe as he fell.
