Explore "The Life Watch" by Lester Del Rey on Textopian. Read with annotations and highlights.
Three hours later, he stood alone in the building that had served as a barracks for a mine crew. He watched the rockets leave, and began opening the airlocks to space. Any bacteria left by the former men would quickly perish, he felt sure. But he had to be thorough.
He had no hope of success yet. He might be keeping a death watch over the human race as the Aliens moved in -- or a life watch, since he was seeking life while they were intent on ending it. But he, at least, was no living thing, and the life detectors of the Aliens should miss him. Somehow, he'd learn enough to seek vengeance among them.
