Gurney couldn't help noticing, with a little shudder, that its mouth-parts consisted of a cutting mandible, and a long, coiled membrane like the ligula of a honeybee. Huge, compound eyes occupied the upper half of the metal insect's face. Gurney's hand had gone out, and was about to close on the little statue; but something in Langford's stare made him change his mind. As his hand whipped back he fastened his gaze on Langford's face with the ire of a peevish child denied access to a jampot. "What in blazes has that to do with your failure to obey orders?" he demanded, with explosive vehemence. "That ship must have used an interstellar space-warp drive to appear out of nowhere in the middle of the Asteroid Belt. And you deliberately let it slip away from you!" Langford shut his eyes before replying. He saw again the myriad stars of space, the dull red disk of Mars and the far-off gleam of the great outer planets. He saw the luminous hull of the alien ship looming up out of the void. An instant before, the viewpane had been filled with a sprinkling of very distant stars with a faint nebulosity behind them. The ship had appeared with the suddenness of an image forming on a screen, out of the dark matrix of empty space. Langford leaned forward, a desperate urgency in his stare. "Mere alienage doesn't justify the crime of murder, sir!" he said. "Attacking an alien race without weighing the outcome would have been an act of criminal folly, charged with great danger to ourselves." Commander Gurney shook his head in angry disagreement. "Just how would you define murder, Langford?" he demanded. "If a highly intelligent buzzsaw came at you would you bare your throat?" Langford ignored the question. "Violence breeds violence, sir," he said, with patient insistence. "Suppose the shoe were on the other foot. Suppose the inhabitants of another planet attacked you without giving you a chance to prove your friendliness?" Langford's eyes held a dogged conviction. "Remember, sir--to issue a warning is an act of forbearance. No reasonable man could mistake a warning for an aggressive act. If their weapons are superior to ours, or they are superior to us in other, truly terrifying ways, they proved their friendliness by warning us. Would you have had me attack their ship without studying that warning?" Gurney's eyes had returned to the statue. He seemed fascinated by the glitter of its folded wings. He had a sudden vision of the metal insect spreading its wings and taking off with a low, horrible droning. Suddenly there was a dull throbbing in the Patrol commander's temples. A frightful dread took possession of him, so that he could hardly breathe; in his mind's gaze he saw a vast, stationary plain that seemed to hang suspended in midair above a fiery sea. Sweeping straight toward him, dark against the glow, were hundreds of flying mantis shapes with their arms upraised in the glow.
