mission to fulfill, and that it won't let me die--at least not until I accomplish what it desires. However, I feel also that it will, or can, do nothing concrete to prevent my being killed. It will probably aid me by convincing you that it would be better to let me live." "Do you feel that its purpose might be much the same as ours, and that it will attempt to convince us of that?" Oliver asked. "Something like that," Buckmaster answered. "At least the urge to kill Koski is so strong within me that I know I would not hesitate if I had the chance, even if it meant my own life."

We have only to lose another key dozen and Olson will have no friends here to aid." "May I offer a compromise?" Buckmaster asked. "As matters stand now, our only chance of winning freedom from Koski's savage rule is to kill him. And to do that we will
