Flicker tried desperately to tear his mind from the agonizing rhythm of the light, to catch and hold the alien thoughts. Confusion rose in his mind, and for the first time he felt a chill of fear. His people knew that these aliens were avaricious and venal--a dozen drained and pillaged star-systems which they had overrun bore witness to that--but he had never even considered, before he started on this mission, that they might kill him without even attempting communication. Why must they kill him? All he wanted was a chance--one brief moment to convey his message to them. Five years of planning, and his own life, had been risked just to get the message to them, to gain their confidence and make them understand, but all he found in these alien minds was fear and suspicion and hate, which had become a single ever-developing crescendo: "Kill it now, while we can!" There were only three of them with him now, but he knew, from some corner of the alien minds, that five others were sleeping in a forward chamber of the ship. He saw himself clearly, alone on an unknown spacecraft with eight alien creatures, gliding through interstellar space at unthinkable speed, bound for that nebulous and threatening somewhere they called home. Their home. He caught a brief mind-picture from one of them of an enormous city, teeming with these alien creatures, watching him, picking at him, trying to question him, deciding how to kill him-- And through everything else came the intermittent burning glare of that terrible white light-- * * * * * Then suddenly the three aliens were leaving the cabin. Flicker sensed their indecision, felt them balancing the question in their minds. Soundlessly, he lifted one eyelid a trifle. The searing light burst in on his retina, blinding him for a moment; then he caught a distorted glimpse of them opening the hatch and withdrawing in their jerking, uneven gait. And still the alien thought came through with a parting jab to his tortured mind: "The only thing we can do is to kill it. The risk of tampering with it is too great. And we don't dare take it back home alive."
