" But then he began to harbor suspicions about his fellow soldiers. He said he thought they were muttering about him, glancing suspiciously at him all the time. One officer in particular troubled Minor, began teasing him goading him, persecuting him in ways that Minor would never discuss. He challenged the man to a duel and had to be reprimanded by the fort commander. The officer was one of Minor's best friends, said the commander---and both he and the friend later said they were incredulous that they had fallen out so badly, for no obvious reason. . . . Minor appeared to have taken a leave of his senses. It was all very puzzling, and to his friends and family, deeply distressing." Seems reminiscent of both Poe and Dostoevsky. Otto Rank once turned his attention to this phenomenon.
