Although it leaves much to be desired from a literary point of view, the subject of this journal--the capture of missionary Margaret Hayes by the revolutionary Simbas of the Congo--is intrinsically interesting. Her private story, of an inflexible faith no matter how strongly challenged, runs counter to the frenzied activities of the insurgents even where its doctrinaire aspects may seem intrusive. Mrs. Hayes, calm, controlled and self-effacing to a fault, naturally delimits the materials, scanting the broader aspects of the revolt and concentrating on her own tribulations. She worked by day, starved and begged for food at night, and occasionally witnessed shattering scenes--a Simba brandishing the leg of a recently murdered priest. Horror such as this is unforgettable for all concerned, and Mrs. Hayes' quiet account will take its place in the quasi-inspirational market alongside those of Lois Carlson and Angeline Tucker.
