SENSE OF OBLIGATION By HARRY HARRISON _It took a very special type of man for the job--and the job was onerous, dangerous, and the only really probable reward was disaster. But when a man who says he knows it's going to kill him asks you to join...._ Illustrated by von Dongen [Illustration] I _A man said to the universe: "Sir, I exist!" "However," replied the universe, "The fact has not created in me A sense of obligation."_ Stephen Crane Sweat covered Brion's body, trickling into the tight loincloth that was the only garment he wore. The light fencing foil in his hand felt as heavy as a bar of lead to his exhausted muscles, worn out by a month of continual exercise. These things were of no importance. The cut on his chest, still dripping blood, the ache of his overstrained eyes--even the soaring arena around him with the thousands of spectators--were trivialities not worth thinking about. There was only one thing in his universe: the button-tipped length of shining steel that hovered before him, engaging his own weapon. He felt the quiver and scrape of its life, knew when it moved and moved himself to counteract it. And when he attacked, it was always there to beat him aside. A sudden motion. He reacted--but his blade just met air. His instant of panic was followed by a small sharp blow high on his chest. "_Touch!_" A world-shaking voice bellowed the word to a million waiting loud-speakers, and the applause of the audience echoed back in a wave of sound. "One minute," a voice said, and the time buzzer sounded. Brion had carefully conditioned the reflex in himself. A minute is not a very large measure of time and his body needed every fraction of it. The buzzer's whirr triggered his muscles into complete relaxation. Only his heart and lungs worked on at a strong, measured rate. His eyes closed and he was only distantly aware of his handlers catching him as he fell, carrying him to his bench. While they massaged his limp body and cleansed the wound, all of his attention was turned inward. He was in reverie, sliding along the borders of consciousness. The nagging memory of the previous night loomed up then, and he turned it over and over in his mind, examining it from all sides.
