In this tale from the golden age of science fiction, the human race has mastered the delicate art of preventing war, whittling it down to a precise mathematical algorithm. However, when signs of revolutionary skirmishes begin to appear, it becomes apparent that a traitor has been disseminating these precious scientific secrets. The task of identifying the source of the leak falls to a team of researchers.
